ROCHESTER, NY — Cade Cavalli, Cole Henry and Matt Cronin are on the Rochester Red Wings’ official roster, which means the next stage of the Washington Nationals’ rebuild is happening just south of Lake Ontario at Frontier Field. But even though their names have sparked excitement in the ballpark lately, this week has been a reminder that rebuilding is incremental.

Cavalli, Henry and Cronin are three of the Nationals’ top prospects. By early June, after Henry and Cronin had been promoted through the club’s Class AAA affiliate, all three were one step away from the majors. Still, the size of this step, and what it would take to complete it, will vary by player. Cavalli, 23, returned from a two-week break Wednesday night and worked three innings against the Worcester Red Sox. Cronin, a 24-year-old reliever, is resting for a bit, with Washington using a break plan now to kick off the season for many of its best arms. And Henry, 22, is in West Palm Beach, Fla., to get his shoulder treated.

Before going on the injured list, Henry recorded his only difficult outing of the year. Against Worcester, Cavalli needed 29 pitches to complete the first, threw two batters in the second and struggled to command his breaking balls throughout. Cronin has not pitched for Rochester since June 17. These are, in theory, the next big-name pitchers who might have a chance in Washington. It’s just going to take patience and time.

“You’re starting to see guys who hopefully will be pieces of the puzzle and bring us another championship,” Red Wings manager Matthew LeCroy said Wednesday afternoon. LeCroy also has Joan Adon, the 23-year-old right-hander who made it to the opening day lineup before arriving in Rochester with a 6.95 ERA in 12 starts with the Nationals.

“But what you have to understand is that the jump from AA to AAA is huge,” LeCroy continued. “And then maybe it will help you see what kind of leap it is from AAA to the big leagues. This is where it gets hard.”

As a boy, Cade Cavalli wrote down his goals and ambitions. Now his dreams are coming true.

Many within the organization believe the Red Wings have the right pitching coach for the job in Rafael Chaves. Players young and old love it. Three months into its first season here, it’s also received rave reviews from Washington’s pitching coordinator Sam Narron and others in the front office. Chaves, 53, has spent his entire 12-year playing career in the minors. Outside of his two years as the Seattle Mariners pitching coach, he has always been a minor league coach.

For the past three seasons, he served as director of pitching development for the Philadelphia Phillies. After being ousted during a player development overhaul, the Nationals hired him while remodeling their staff. Chaves is soft-spoken and smiles quickly. He is originally from Puerto Rico and bilingual, which helps him overcome language barriers. And his delivery – calm, measured, each word spoken as if balanced on the one before it – has its pitchers gripped.

“My job is to develop players. If I don’t do this, then why am I here? Chaves said. “I must be proud of their development. When they’re doing well, they’ve done a good job. When it’s not, I have to think, ‘Okay, where am I failing?’ It’s something that kept me in this game for a long time. I think it’s important that you care about your players and show them that.

Midway through the interview, Chaves was interrupted by Matt Lipka, one of Rochester’s outfielders, who yelled, “You put in this article this guy needs to get to the show!” And I love him.” About 30 seconds later Lucius Fox, an infielder, stopped to say, “The best coach! Put that in there!” At Lipka, Chaves paused and whispered, “I love you too.” To Fox, he only laughed, saying his goal is to get players to the majors, not himself.

Chaves has constantly evolved as a coach, learning technology and analysis, proving that curiosity can hide beneath an old-school exterior. He sees these tools as the best way to reach this generation.

“I had to be willing to learn and not be closed-minded,” Chaves explained. “The first step to solving a problem is that you have to accept it, right? Like people who have an addiction, they have to admit that they have an addiction. It’s no different with the people who resist change in this sport. I realized that if I don’t adapt to the game, the game is going to go over my head and go on without me.

Svrluga: Four outs in one inning? It was also a surprise for the Nationals.

Sitting in the Red Wings dugout, he discussed the rotational efficiency of Cronin’s high-end fastball and then the granular relationship between the fastball and Cavalli’s change. Did he come to like that side of the game?

“I think it’s very productive, yes, because it gives you objective information and they want to see that,” Chaves said. “It’s not rocket science. I didn’t have to build the machine, I just have to learn what the machine reads. It’s doable.

Between Chaves, Narron and LeCroy, the balance sheets of Cavalli, Cronin and Henry are emerging. Cavalli needs to refine his fastball control inside and outside the area. Southpaw Cronin, who had a 0.00 ERA in AA before a few bumps in Rochester, needs to refine his curve and throw more shots with it. Henry must stay on the mound.

In early August, once the trade deadline passes, the Nationals will likely pull a small handful of replacements from Rochester. But if Cavalli, Cronin or Henry aren’t among them – whether for health or performance reasons – it won’t be alarming. They are the opposite of palliatives in a lost season. They are supposed to be the future of the Nationals, bit by bit.

“We probably don’t talk enough about what the covid year meant for young players,” said Tyler Clippard, now a veteran Rochester reliever. “My 22-year-old season was literally where I learned the most of my career. So if Cade is what, 23, I really see him as 22. That goes for all those guys. They missed a year full of development and it’s no joke.

“I hope the organization gives them the time to grow and understand that. It will end up being better for everyone in the long run.

ESA’s contribution to NASA’s Orion on the return to the Moon • The Register https://stlouisrocketry.org/esas-contribution-to-nasas-orion-on-the-return-to-the-moon-the-register/ Tue, 28 Jun 2022 09:53:00 +0000 https://stlouisrocketry.org/esas-contribution-to-nasas-orion-on-the-return-to-the-moon-the-register/ Interview NASA has set late August as the launch window for its much-delayed Artemis I rocket.

Interview NASA has set late August as the launch window for its much-delayed Artemis I rocket. Already perched atop the booster is the first ready-to-fly European Service Module (ESM). Five more are in preparation.

The industrial director of Airbus, Siân Cleaver, who The register met at the Goodwood Festival of Speed’s Future Lab, is tasked with managing the assembly of the spacecraft, which will provide propulsion, power, water, oxygen and nitrogen to the Orion capsule.

Appearing to the world as an evolution of the European Space Agency’s (ESA’s) International Space Station (ISS) ATV freighter, the ESM is unpressurized and approximately 4 meters long, including Orbital Maneuvering System Engine (OMSE), which protrudes from the base.

The OMSE will also look a bit familiar: “We took those straight from the old space shuttles,” Cleaver told us, which gives a nice symmetry considering the mission.

The Space Shuttle Orbital Maneuvering System has the legacy of the Apollo Service Module and although those used by the EMS will not return to Earth, the technology has proven itself.

Unfortunately, old space shuttle bits are a limited commodity. “We’ll fly them up to ESM-6,” Cleaver said, “beyond that, we’re starting to think about using a new engine developed based on that.”

Currently, Airbus is contracted to build six ESMs. The first awaits this first launch, without a crew. The second is already in Florida, awaiting integration with the next Artemis rocket and the third, which may well welcome the first astronauts to set foot on the Moon since the days of Apollo, is gathering in Bremen, Germany .

The first batch of ESM evolved as the work progressed. Lessons learned from the ESM-1 filter into the ESM-2 and so on (and no doubt whatever is learned from that first critical test flight will also be mixed in the pot.) “There’s there were a lot of changes between the ESM-2 and the ESM-3,” Cleaver said. “…ESM-3 was a slightly different size than ESM-1 and 2 because they were thinking of pushing a gateway module with it…”

Plans by NASA and its international partners to launch modules for the Gateway, a space station intended for near-rectilinear halo orbit (NRHO) around the Moon, have been somewhat fluid over the years. A plan called for the launch of the European Supply, Infrastructure and Telecommunications System (ESPRIT) and Housing and Logistics Outpost (HALO) on Artemis 3, but has since been scrapped in favor of commercial launches separated.

Things should calm down somewhat after ESM-3, although project management of such a spacecraft continues to be a challenge. “I have a spreadsheet,” Cleaver said, “that has all the different equipment and all the different subcontractors, and I track all the delivery dates that way.”

“So it’s pretty basic in that sense,” she laughed.

One of the challenges is the international aspect of the business. “We work all over Europe,” she said, “and we also work with American suppliers, who do things very slightly differently than what we are used to doing in Europe in terms of documentation. and process.

“So it’s really about making sure everyone’s on the same page, everyone’s working the same way, and everyone’s meeting everyone’s deadlines.”

Cleaver is looking forward to the next batch of ESMs, which will move further to a mass production line compared to ESMs 1-3. Tendering is underway for ESMs 7-9 and the intention is that things get cheaper and faster as batches of starships are ordered.

But there remain those crucial first flights, the first unmanned and the second (hopefully) with. “We had to change everything in the ESM,” Cleaver said of the ATV comparison, “to make it completely crew safe.”

“With ESM-1, it’s a test: ‘Let’s try this, let’s try that.’ With ESM-2 you can’t do that – people’s lives are at stake here.”

Therefore, Cleaver isn’t too concerned about the ongoing delays with Artemis 1. “We can’t take any chances,” she said. “I think we’d rather be delayed than have catastrophic failures and errors that can result in the loss of the mission. That’s just not an option for us.”

“We have to make sure it’s right, and it’s right the first time, which is why it pays to be careful when talking about launch dates.”

And as for when can breathing resume on the ground after Artemis 1? “I think for the guys on the European Service Module team,” Cleaver laughed, “it will be when the Orion module separates from the ESM right at the end of the mission.”

Or maybe a bit later, once all sensor data from the ESM-1 has been confirmed as returned. After all, unlike the space shuttle from which its big engine is derived, the European service module certainly won’t make a runway landing on Earth. ®

‘Elvis’ debuts at $31 million as ‘Black Phone’ earns $23 million https://stlouisrocketry.org/elvis-debuts-at-31-million-as-black-phone-earns-23-million/ Sun, 26 Jun 2022 15:25:36 +0000 https://stlouisrocketry.org/elvis-debuts-at-31-million-as-black-phone-earns-23-million/ Austin Butler and Tom Hanks in “Elvis” Warner Bros.

Elvis opened strong this weekend with a $30.5 million Friday-Sunday debut right next door Top Gun: Maverick’s shockingly huge (also $30.5 million) fifth weekend gross. Whichever movie tops the domestic box office when the final numbers drop tomorrow, they’re both winners. I’ll talk about the Tom Cruise-directed sequel later, but Tom Hanks’ co-starring musical biopic benefited from the premiere. One of the best marketing pieces a movie can have is a good trailer that airs before a smash hit aimed at similar demographics. Think about the deep impact teaser attached to Titanic or the zootopia DMV spot aired before the force awakens. With all the pre-summer concerns that older, erratic audiences (Elvis Presley isn’t exactly huge with kids yet) wouldn’t show up, Warner Bros. was shot in the arm at the last minute when Top Gun: Maverick topped domestic $520 million thanks in part to older, erratic moviegoers. Guess Which Trailer Played Before Most Theatrical Screenings Of Top Gun 2.

WBD still sold the Baz Luhrmann-directed movie hell. Elvis got center stage treatment at the studio’s CinemaCon presentation, and its IMAX-compatible trailer has been streaming ahead of big movies since President’s Day weekend, including The Batman, Doctor Strange in the Multiverse of Madness and yes, Top Gun: Maverick. Additionally, the film’s performance suggests a pre-Covid normality whereby live-action musicals (including biopics and music-centric melodramas) were among the safest theatrical subgenres since it was about “event films”, even in the era of VOD/streaming. Before Covid we had the likes of (casual and not full) Mamma Mia: Here We Go Again, Pitch Perfect 2, La La Land, The Greatest Showman, Straight Outta Compton, A Star Is Born and Bohemian Rhapsody. Over the past year, we have had, alas, West Side Story, In the Heights and Dear Evan Hanson. Even the Disney ones Encanto (comparatively) stumbled with $250 million worldwide while Universal although Illumination’s Sing 2 soared to $400 million.

Elvis Presley, like Freddie Mercury, Elton John and Ice Cube before him, qualifies as a “brand figure” alongside Deadpool, Michael Myers or Pete “Maverick” Mitchell. Tom Hanks *as* Colonel Tom Parker qualified as a star + character concept cast. That the role was skewed to Hanks’ on-screen/off-screen persona was a calculated gamble (Hanks is usually the strongest commercially when playing real-life American heroes) that paid off. Add generally positive reviews, in which even some of the pans made the film a can’t-miss hallucinogenic acid trip, while Austin Butler (a Disney Channel/Nickelodeon vet who will star alongside Timothée Chalamet and Zendaya in Dune part 2) received the “star is born” media treatment in the weeks leading up to its release. None of this is rocket science, but it’s refreshing to see that it still works in our current theatrical environment. Elvis just landed the biggest opening for a (non-action) drama in over two years.

Let it happen a decade later magic mike opened with $39 million is a happy coincidence. Warner Bros., when it’s on its game, is better than anyone else in Hollywood at turning relatively unconventional biggies into throaty theatrical hits. Supposing Elvis doesn’t drop dead after this opening, and decent reviews, an A- from Cinemascore, and a lack of adult biggies for the rest of the summer suggest it won’t, its strong debut stands alongside Gravity, American Sniper, San Andreas, It, Crazy Rich Asians, Joker and (on a Covid curve) Dunes. If it’s like legs Mama Mia: here we go again (121 million dollars on debut at 35 million dollars), Elvis cracks 100 million dollars in the domestic market. If it’s (less likely but we’ll see) legs like Rocketman ($96 million/$26 million) or Bohemian Rhapsody ($217m/$52m), it will end with $112-125m. Conversely, the legs like Straight outta Compton ($161 million/$60 million) gets the movie from $85 million to $80 million domestic.

universal, including Ted opened with $54 million right next door magic mike ten years ago had the other big start to the weekend. Acclaimed Blumhouse The black phone opened with $23.3 million in its Friday-Sunday domestic debut. Scott Derrickson and C. Robert Cargill’s ’70s chiller, about a kidnapped boy who receives help from the killer’s previous victims, was slated to open in early 2022. However, heavy festival buzz and reviews led Universal to keep the film, adapted from a Joe Hill short story, until this weekend. Credit reviews and word-of-mouth (a solid for B+ Cinemascore horror), plus the Blumhouse brand name and “marquee value” of Scott Derrickson (who helmed Strange, Sinister Doctor and The Exorcism of Emily Rose) and Ethan Hawke (who has been a go-to for all sorts of genre films for decades). Its sinister fantasy horror and gruesome child murders are seen as the kind of fantasy escape we need to distract us from the horrors of the real world.

Legs equal to those of David Sandberg Curfew ($67 million from a debut of $21 million in July 2016) get the movie from $18 million to $70 million domestic, while legs are on par with Fede Álvarez don’t breathe ($89m/$26m) brings it closer to $80m. Guess it could be preloaded like Blumhouse’s terrific (and appreciated) happy day of the dead (which outperformed the opening weekend thanks in part to the Friday the 13th opening and ended with $56 million after a $26 million launch), but I won’t cry The black phone “only” grossing $50 million. It has already grossed $35 million worldwide. It might have been the first weekend since July 2016 where the top five movies all grossed $20 million, but since Pixar Light year crashed and only made $18 million, it’ll have to settle for being the first weekend with four $20 million earners since Thanksgiving weekend in 2018. That’s a problem from Disney, not from Hollywood.

A24 launched Marcel the shod shell in six rooms. The charming and poignant feature adaptation of Dean Fleischer-Camp and Jenny Slate’s YouTube short film series, for which Nick Paley and Elisabeth Holm also receive feature writing credit, grossed $169,606 over the week. -end of opening. That’s an average of $28,267 per theater for the live-action/animated coming-of-age family film. It’s going wide on July 15, and that’s great (my 11-year-old dug it too). I’m curious if it gets a Cinemascore rating when it widens, if only for the comedic value of that real crowd pleaser that sounds like an A and ‘clash’ with the usual mark of A24 (often quite good) “Haven’t you seen an A24 Logo before this feature? ” horror films. My local Regal was packed Friday night with a variety of moviegoers waltzing through various auditoriums. Crazy theory: But if studios release movies in theaters, audiences will go to those theaters and watch those movies.

2023 Chevy Corvette Z06 Exhaust Rating Explained In A Short Video https://stlouisrocketry.org/2023-chevy-corvette-z06-exhaust-rating-explained-in-a-short-video/ Wed, 22 Jun 2022 23:51:00 +0000 https://stlouisrocketry.org/2023-chevy-corvette-z06-exhaust-rating-explained-in-a-short-video/ The expectation for the 2023 Chevrolet Corvette Z06 continues to grow.

The expectation for the 2023 Chevrolet Corvette Z06 continues to grow. We’ve seen countless videos and frankly, the wilder C8 couldn’t get to the metal soon enough. Chevy wants to add to that anticipation by releasing a short Corvette Academy video on one of the most talked about aspects of the new Z06: its exhaust note.

The video, embedded at the top of this page, attempts to explain the Science behind the glorious Corvette Z06 exhaust note, seen and heard at the recently concluded 106th Indianapolis 500. It’s not rocket science, should we say, but it’s not far from amazing.

Chevy stresses that it wants Corvette C8 Z06 owners to feel like they’re in an exotic car based on the vibrations they feel and the sound they hear. To accomplish this, the Z06’s exhaust goes into center-mounted tips (not available outside the US) or bezels that are part of the car’s rear fascia, designed to reflect sound back to the cockpit for this visceral experience.

It should be noted that the engine of the Z06 is the largest flat-crank V8 in the world. As Chevy says, it’s something that doesn’t exist in any other type of engine the company has had in the past.

Chevy also explains that there are two sets of valves that help alter the exhaust note depending on use – intake manifold valves and variable exhaust valves. These gates allow for adjustments in 2-degree increments, which translate to four exhaust note modes in the Z06. In contrast, the previous configuration was simply open and closed.

There are four exhaust modes: Weather, Tour, Sport and Track. The weather is the calmest of the four, made to make your neighbors always love you. The tour is a bit louder than the weather, while the sport is even angrier. For maximum aural pleasure, Track Mode opens all the floodgates so the driver can feel the maximum potential of the new Corvette Z06.

With Corvette’s configurator still not showing the Z06, we’re pretty sure aspiring owners are worried about when they’ll be able to get their hands on their glorious-sounding future supercar.

Apple TVs are a hugely popular item with smart TV fans, but the brand is known to have audio issues that can hamper the viewing experience.

Just imagine settling down to have a good time watching a highly anticipated movie or your favorite TV show until your Apple TV sound fails.

Luckily, many issues with no sound on Apple TVs are caused by setup and installation issues.

So before you call a pro and shell out big bucks for simple repairs, check out this list of solutions for Apple TV no sound problem.

We’d love to know it saved you time and money. Let’s see how to fix an Apple TV that has no sound.

Make sure your Apple TV is not muted

Sometimes people give up on the most obvious solutions thinking that there’s just no way the problem could be that obvious.

The TV can simply be muted or reduced to a minimum volume, which makes the sound inaudible.

Before taking any of the more advanced steps, just make sure your volume is at a normal level that you’re used to watching your shows and movies. Sometimes the answer is as simple as that.

Check the HDMI cable

Often it is the connection that is the problem. Often the hardware connection of the HDMI port ends up not fully transposing all the intended signals, such as the audio channel.

Incorrect audio connections may be due to a problem with the HDMI cable itself or its connection to the TV. Before replacing the HDMI cable, a recommended tip is to disconnect the cable from the TV and then reinsert it.

If that doesn’t fix the problem, disconnecting the HDMI cable on both sides and reversing the HDMI port connections may also do the trick.

If not, it might be a good idea to just completely replace the HDMI cable. Make sure the replacement is a new wire to avoid any old issues with the wiring being used.

Restart your Apple TV

If turning off and on again doesn’t do the trick, nor does the set of HDMI troubleshooting tips, the problem may be due to a recent audio driver installation or other firmware changes that occurred during the Last update.

If these changes haven’t had a chance to process properly, the best solution is to restart the Apple TV itself.

This involves navigating to the system menu and going down to the “Restart” option. This action will restart the TV and include refreshing all apps.

Set your Apple TV’s audio mode to Auto

One thing people often forget is that their TV is hooked up to a home theater system or soundbar. When these devices are set to default, the TV may not output sound because these devices are turned off.

If not, in some cases, the audio streaming itself may require a particular bitrate to stream the audio.

The TV can detect the best audio mode if one were to navigate to the video and audio settings section, and set the audio mode to “Auto” after verifying that the desired speakers are the correctly selected audio.

Change your Apple TV audio format to stereo

It is also possible that the TV is not picking up an adequate signal to output the audio, in which case go to the Settings menu and select the Audio and Video option, then set the Dolby Digital Out setting to “Off”.

This should allow the signal to be stronger. Some firmware versions offer the option to select a format type from Dolby Digital 5.1 to “Stereo”.

Change your Apple TV’s audio output to PCM

If after changing the audio format of your Apple TV, you still get no sound, you will change the audio settings to PCM.

PCM stands for Pulse-Code Modulation and is the standard form of digital audio in computers.

Here’s how to change your Apple TV sound to PCM.

  • Hurry Settings on your TV remote control.
  • Go to the Sound Settings option.
  • Select audio and access audio format.
  • Choose the PCM format.

Keep in mind that these steps may be different depending on your TV brand. Either way, it should be easy to find the PCM option on your TV once you go to the audio format settings.

Soft reset your Apple TV Box

If turning something off and on again isn’t your first attempt at troubleshooting a technical issue, you’re troubleshooting it wrong.

Most problems are easily fixed by simply turning off the electronics in question and turning them back on a few seconds later.

This extremely simple action takes care of a vast majority of common issues with the Apple TV, including any audio issues it might experience.

To reset your Apple TV, turn everything off, then unplug your Apple TV box from the wall outlet.

Wait about 60 seconds before plugging it back in. If your Apple TV still does not play sound, you may need to perform a hard reset. Follow the next section for step-by-step instructions.

Hard reset your Apple TV Box

Please note that a hard reset will reset your Apple TV to its original settings and erase all data, including your accounts and configuration.

Make sure to keep your Apple TV plugged in and have an uninterrupted internet connection until the hard reset process is complete.

1. Select Menu on your Apple TV remote.

2. Enter the Settings application.

3. Scroll to System.

4. Then click on Reset under Maintenance.

Apple TV reset option

5. Then select Reset and update.

6. Finally, select Reset and update to reset your Apple TV.

This will return your Apple TV to its factory settings and also update it to the latest version of tvOS.

After the reset process is complete, make sure to set the audio format to Stereo.

Contact Apple Support

If at this point you still can’t hear sound from your Apple TV and you’ve tried all the suggestions above, it might be time to contact Apple Support.

They may have other tips or steps for diagnosing and fixing audio issues. If they can’t fix it, you might want to find a reputable TV technician.

Many electronics stores have a support team that will come to your home and fix your TV.

You can let them know about all the steps you’ve already tried to make their service visit as efficient as possible and save everyone time.

Final Thoughts on Apple TV No Sound Issue

As you can see, fixing your Apple TV with no sound problem is not rocket science provided you know what to look for.

Usually, a simple power cycle can fix the problem when your Apple TV is not working. Other times, you may need to follow all of the tips above in order until you find the solution that works for you.

We hope you found the troubleshooting tips in this guide helpful in resolving sound issues on your Apple TV.

Let us know if this helped resolve this issue. If you managed to do anything else, leave me a comment below!

Artemis II engine section proceeds to final assembly

New Orleans LA (SPX) June 10, 2022

Greenland’s isolated polar bear population adapts to climate change

An isolated population of polar bears in Greenland have ably adapted to the decline of the sea ice on which they depend as a sealing platform, offering a glimmer of hope for this species in at least some places of global warming. Arctic. This population of several hundred bears, inhabiting part of the southeast coast of Greenland in the Denmark Strait, survived with only brief access to the ice formed from frozen seawater by instead hunting chunks of freshwater ice breaking away from the massive Greenland Ice Sheet, researchers said on Thursday.

South Korean aerospace and defense company Innospace will be the first private company to send a rocket from the Alcantara launch center in northern Brazil in December, the president of the Brazilian Space Agency told Reuters on Friday. Carlos Moura. Innospace, which plans to make small, low-cost satellite launches more accessible from multiple locations around the world, is still developing its rocket and will test it with an experimental launch from Alcantara, Moura said in an interview.

China finds signs of water in Moon’s ‘ocean of storms’

Chinese scientists have found signs of water in samples recovered by China from a lava plain on the moon, bringing them one step closer to understanding its origin there – a crucial question for future lunar exploration. In a paper published in Nature Communications this week, scientists said they analyzed remnants of solidified lava recovered by an unmanned Chinese mission from the plain known as the “Ocean of Storms” and found evidence of water under form of hydroxyl locked in a crystalline mineral known as apatite.

Later this year, the United Launch Alliance will end its workhorse rocket, the Atlas V, and begin the era of the Vulcan rocket.

Atlas V has had an impressive 93 launches in its nearly 20-year history, making it the longest active launcher in the United States. Additionally, Atlas V had only one partial failure, when the rocket was unable to insert a payload for the National Reconnaissance Office into its intended orbit – but after the satellites were able to compensate for the problem, the NRO considered it a mission success.

With 23 launches remaining, Atlas V’s impressive run is over – but why? There are many reasons, but Russian aggression in Ukraine plays a major role.

Vulcan: Vulcan-Centaur setup and specs

Replacing a primary launch vehicle is no easy task, and ULA has every reason to stick with Atlas V. Despite this, the company is confident of replacing it with a bigger and better rocket. Enter Vulcan. Vulcan has a more complicated “modular” upper stage, and the entire rocket is built on a completely different system than Atlas V.

Currently, ULA will launch Vulcan with a “Vulcan-Centaur” configuration. This “Centaur” upper stage is equipped with two RL10C engines, which marks nearly 60 years of use for this engine model. The RL10 series has been fired nearly 700 times in space and represents a continuation of ULA’s “play it safe” attitude. Similarly, Vulcan Centaur can be fitted with up to 6 solid rocket boosters, similar to the variants found on Delta II and Delta IV rockets.

In stark contrast, the lower stage is powered by a pair of controversial BE-4 engines, made by Jeff Bezos’ aerospace company Blue Origin. Originally planned to be custom built for Blue Origin’s New Glenn launcher, ULA eventually agreed with the company to use these engines for Vulcan Centaur.

Blighted by constant development and production delays, Blue Origin initially claimed the engines would be “ready to fly” by 2017, but this has been repeatedly pushed back. Apparently, the relationship between ULA and Blue Origin has been rocky due to the five-year delay. The BE-4 has never been flight tested, so Vulcan’s first launch later this year will mark its first real use – a possible risk point for a risk-averse company like ULA.

Atlas V customers and launch history

The Atlas V rocket was a workhorse not only for ULA but also for its customers. In particular, the Atlas V has been a favorite launcher for the military, thanks to its near-perfect track record. The ULA has launched several payloads, including “military comsat” satellites, reconnaissance satellites for NRO, and GPS satellites operated by the Department of Defense.

It is also the launch vehicle of choice for the Boeing Starliner, which has just completed its first mission to the International Space Station.

Atlas V is no slacker when it comes to science missions either. In 2005, an Atlas V rocket launched the coveted Mars Reconnaissance Orbiter, which continues to return beautiful images and conduct valuable research into the geology of Mars.

Other NASA missions launched on an Atlas V include:

  • The Pluto-flyby New Horizons mission, currently on its way out of the solar system
  • The Solar Dynamics Observatory, which constantly monitors our home star
  • Juno, a Jupiter orbiter that studies the interior of the largest planet in our solar system
  • The Curiosity rover, a nuclear-powered workhorse that surveys Mars for signs of past water activity
  • Its successor, the Perseverance rover, which is looking for signs of ancient life
  • Solar Orbiter, an ESA mission to investigate the polar regions of the Sun
  • And most recently, Lucy, a mission that will study a group of asteroids in front and behind Jupiter called the Trojans, which could represent some of the most pristine material in the solar system.

With such a comprehensive catalog, Atlas V has allowed NASA to accomplish a lot.

ULA Vulcan cost and first launch

The first launch date of the Vulcan is set for this year, although there is no official date yet. SpaceflightNow, which keeps a solid schedule of space launches, has the flight listed for “late 2022.” A launch date of 2022 was reiterated by ULA chief executive Tony Bruno in March.

The payload for this first mission would be the Peregrine lunar lander, a private vehicle built by Astrobotic. It will take with it a secondary payload from Celestis containing the ashes among other things, star trek creator Gene Roddenberry and his wife, Majel Barrett Roddenberry, who played many roles in the franchise. Roddenberry died in 1991, while Barrett Roddenberry died in 2008.

Reuters reported in 2020 that Vulcan would cost around $100-200 million per launch, depending on the configuration. The Atlas V can cost up to $153 million per launch, but with a lighter lift capacity.

Launch capabilities between Atlas V and Vulcan (and Starship)

As its mission history shows, Atlas V is quite a flexible rocket. It is capable of sending payloads to a wide variety of locations, including low Earth orbit (LEO), medium Earth orbit (MEO), geostationary transfer orbit (GTO), orbit heliocentric, etc. This diversity of orbits is possible thanks to the launch capabilities of the rocket. In its 551 configuration, Atlas V placed up to 18,800 kg in LEO. Likewise, he threw 8,900 kg in GTO.

Vulcan, an even more powerful rocket, could theoretically launch up to 27,200 kg towards LEO if equipped with six solid rocket boosters. This Vulcan Centaur VC6 configuration could also lift 13,600 kg to GTO. (A proposed Vulcan Centaur Heavy has the same LEO/GTO launch capability as Vulcan Centaur VC6.)

Notably, it would still put ULA behind SpaceX in launch capability should SpaceX’s Starship dreams come true. The company estimates that its giant rocket could lift at least 100,000 kg to LEO and 21,000 kg to GTO. Of course, massive rockets like Starship are faced with the question of whether anyone needs such payload capacity. Both Atlas V and Vulcan are designed to launch the payloads of the present, which are also designed with the limitations of these rockets in mind.

How Russia’s annexation of Crimea prompted the switch to Vulcan

Like anything else, Atlas V can’t stay in the spotlight forever. The rocket is based on Russian-made RD-180 engines. Russian-made engines are a significant security issue for the US military. Problems arose even before Russia’s current invasion of Ukraine. Particularly after the Russian annexation of Crimea to Ukraine in 2014, the United States government began to pursue contingency plans in the event of sanctions being imposed on the Russian Federation. Shortly thereafter, a ban on the purchase of RD-180s was passed—and overturned the following year—by Congress.

In response to the uproar caused by Russia’s capture of Crimea and the reaction of Congress, ULA announced that it would contract Blue Origin for its BE-4 engines. Since the BE-4s rely on oxygen-rich liquefied natural gas (LNG) that is less dense than the RP-1/LOX mixture of the RD-180, the engines require much larger fuel tanks. This is one of the main reasons ULA decided it was time to develop a new rocket to replace Atlas V.

Reverse analysis – In the wake of Russia’s unprecedented invasion of Ukraine, it appears the ULA made the right call in choosing to move away from the RD-180s when they did. Given that recent sanctions have deemed “normal business relations” with Russia null for the foreseeable future, ULA is relying on Blue Origin more than ever to supply its BE-4 engines.
