SpaceX Raptor Engine COMPLETELY Humiliation Blue Origin BE4 Engine.

Science Of Space 1/29/2022

A few months ago spacex completed its 100th raptor engine, this extraordinary milestone was achieved in just 29 months, a little over two years blue origin's rocket engine's development started, work on the be 4 engine since 2011.

Importantly, they said the be4 would be ready for flight by 2017, but at this very moment blue origin's powerful be4 engine is more than four years late.

The first flight test of the new engine is now expected no earlier than 2022, on the vulcan rocket, this is a big problem and we need to talk about it. So how did blue origin's be4 turn into a joke, whereas spacex's raptor is the leading example of the industry.

SpaceX tests fully stacked Starship rocket for the first time

TeslaRati by Eric Ralph 3/17/2022

https://www.teslarati.com/spacex-starship-first-full-stack-cryoproof/

After rapidly stacking Ship 20 and Booster 4 the evening prior, SpaceX appears to have begun testing a fully stacked Starship rocket for the first time ever.

Though the test SpaceX subjected Starship to was by no means ambitious and in spite of the fact that it no longer appears that Ship 20 and Booster 4 will ever fly, the first test of the first fully integrated prototype of a new rocket is still an immensely significant achievement – particularly so for the largest rocket ever built.

Standing around 119 meters (~390 ft) tall, Starship is unequivocally the largest and most voluminous rocket ever built. With its 29 Raptor V1 engines, the fully assembled Ship 20 and Booster 4 (B4) stack would have likely weighed around 4000-5000 tons (9-11M lb) and been able to produce around 5400 tons (11.9M lbf) of thrust at liftoff – substantially heavier and more powerful than Saturn V or N1, the largest rockets ever successfully and unsuccessfully launched.

For its first fully-integrated test, though, SpaceX appears to have put Starship through a fairly limited cryogenic proof – a test where flammable propellant is replaced with a similarly cold (cryogenic) fluid that’s similar enough to subject a rocket to similar thermal and mechanical stresses. For Ship 20 and Booster 4’s combined debut, Super Heavy was filled maybe 10-20% and Starship around 25-50% of the way with either liquid nitrogen (LN2) or a combination of LN2 and liquid oxygen (LOx). It’s difficult to tell but it’s unlikely any methane (LCH4) fuel was involved.

SpaceX rapidly constructing Starship’s first Florida launch pad and tower

TeslaRati by Eric Ralph 4/13/2022

https://www.teslarati.com/spacex-starship-florida-launch-pad-tower-progress/

After restarting work on the project a few months ago, SpaceX appears to have gotten back up to speed and begun to make rapid progress on the construction of Starship’s first Florida launch pad and tower.

Located at NASA’s Kennedy Space Center (KSC) Launch Complex 39A facilities, SpaceX has intended to construct a Starship launch site there for several years. A serious attempt was made in late 2019 but SpaceX soon abandoned the effort and redirected its energy towards Starship prototyping and a much different launch pad design. Two years later, SpaceX’s second attempt shares only a little in common with the first. Both are to be located within the eastern half of Pad 39A’s shield-like footprint, although the specific location of the tower and launch mount has been modified. If this attempt comes to fruition, Starship’s first East Coast launch facilities will still sit just a few hundred feet away from the only SpaceX pad capable of launching Crew Dragon, Cargo Dragon, or Falcon Heavy.

Beyond those two characteristics, SpaceX’s second attempt is almost entirely different.

Instead of continuing with an older launch pad design, Starship’s 39A facilities will likely be close to a direct copy of Starbase’s first orbital launch site (OLS), which SpaceX began constructing in earnest in late 2020. It’s safe to assume that some lessons have been learned from Starbase OLS construction and that some modifications will be made to the Florida pad’s design, but no obvious changes are thus far visible.

Most of the visible work SpaceX has done this year centers around the company’s KSC-based Roberts Road facilities, where it has built a major Falcon processing facility and a staging yard for Starship pad construction and broken ground on a massive East Coast Starship factory. At that staging yard, SpaceX began assembling prefabricated sections of Starship’s Pad 39A ‘launch tower’ around March 10th after tower parts began arriving at KSC sometime in February. Within two weeks, SpaceX had completed the basic structure of two tower sections. Another two more weeks after that, around April 11th, a third section had reached a similar level of completion and SpaceX had begun assembling a fourth.

Elon Musk just SMASHED Tory Bruno & BE-4 engines on social media...

Elon Musk just SMASHED Tory Bruno & BE-4 engines on social media...#STARSHIPFANS

Elon Musk has just officially destroyed Tory Bruno with only a picture of his powerful Raptor 2 engines.
How exactly does this happen?
Everything will be exposed in today's episode.
Ok! Let's get started...
"Where are my engines, Jeff?"
After a long time of delay, ULA finally had this question here.
On Apr 26, the CEO of United Launch Alliance, Tory Bruno shared this picture of the BE-4s engines.
He said" Engines!!  Vulcan Flight BE-4s heading to the build stand".
This means Blue Origin now nears the critical point of delivering flight-ready BE-4 rocket engines to United Launch Alliance.
But this is only the combustion chamber and the nozzle, and the pumps are in assembly elsewhere in the factory.
"We all know they still don’t work", a Twitter named Scotty B questioned.
Bruno seems to be annoyed and replied immediately: "No. Thousands of seconds of run time. Full throttle range. dozens of starts. Performing better than my expectations"
But when being asked:" Are these flight ready?"
He only can answer: "Not yet.  Still being assembled."

In fact, except for having a real photo of BE-4 engines, Tory Bruno has repeatedly asserted his confidence with Vulcan and BE-4.
During a panel at the Satellite 2022 conference last month, Tory Bruno announced that he expected the first launch of the Vulcan “later this year".
That schedule is driven by the completion of testing of the BE-4 engine that powers the first stage of Vulcan and the delivery of the first flight units from Blue Origin. “The engine is in great shape,” Bruno said. “It is performing better than I anticipated.”
Bruno said he expected to receive the first two flight models of the BE-4 in the middle of the year, “which supports me flying before the end of the year.” He added that testing of the engine is also going well, including the firing of the engine three times a week “on a sustained basis” at a Blue Origin test site.
“We’re very pleased with where the BE-4 is and we expect to fly this year as a result,” he said.
While Vulcan remains publicly on schedule for the first launch in 2022, Jones ruled out any chance that New Glenn will launch before the end of the year, a schedule that the company had previously cast doubt on. “The runway is closing on 2022”
Blue Origin has to balance New Glenn development with the completion of the BE-4, which will be used by both New Glenn and Vulcan.
“It’s fair to say you’re focusing on your most important customer, delivering BE-4s so I can fly this year,” quipped Bruno.
Anyway, this seems really good news for ULA.

 New SpaceX Booster, Starship and FAA Approval Tracking to Possible July Orbital Launch

Next Big Future by  Brian Wang May 11, 2022   

https://www.nextbigfuture.com/2022/05/175857.html

SpaceX COO and President Gwynne Shotwell says the orbital launch of Super Heavy Starship should be June or July from Boca Chica, Texas, pending FAA approvals. Shotwell said SpaceX views human #Mars exploration and nuclear propulsion systems as “inevitable”.

The FAA has revealed that SpaceX has completed four out of five processes for the Environmental Assessment. However, even with all Environmental Assessments complete this will not guarantee that the FAA will issue a launch license. SpaceX’s application must also meet FAA safety, risk, and financial responsibility requirements.

Once Section 4(f) is behind them, the FAA and SpaceX and the Final PEA completion needs the approval of all relevant paperwork. The FAA’s targeted completion date, currently May 31st, 2022, may be achievable.

SpaceX continues Super Heavy Booster 7 testing at Boca Chica Village

Tesmanian  by Evelyn Janeidy Arevalo May 11, 2022

https://www.tesmanian.com/blogs/tesmanian-blog/cryo-booster-7

SpaceX is rapidly developing its next-generation launch system designed to revolutionize space travel. SpaceX founder Elon Musk aims to design a fully-reusable Starship, capable of transporting tons of cargo to and from Mars. This ambitious endeavor has never been achieved in the aerospace industry. Building a fully-reusable launch system is the "holy grail" of rocket technology, says Musk. Reusability is crucial to decrease the cost of spaceflight enough to actually be able to send thousands of humans to the Red Planet, as well as megatons of cargo for survival on the rough Martian environment.

SpaceX feels ready to launch the first Starship to orbit at the sandy beach at Boca Chica Village located at the southernmost tip of Texas, along the border with Mexico. This week, SpaceX is putting its gigantic Super Heavy Booster 7 rocket prototype to the test at the Starbase launch site. Booster 7 is the first that will be used to propel a Starship prototype to orbit. The 230-foot-tall Booster 7 was transported to the launch pad on May 6 after engineers repaired an internal propellant tank structure that got damaged during the first test campaign last month.

This week, engineers resumed the booster’s test campaign and completed a pair of cryogenic proof tests on May 10 and May 11. The tests gather data about the stainless-steel rocket's structural integrity by filling it up with liquid nitrogen to simulate the pressure of propellant. The pressure test(s) allows engineers to assess if the stainless-steel vehicle is strong enough to withstand the stress of spaceflight; It also serves to check if there are any leaks in the propellant tanks and overall structure. Local space enthusiasts, Spadre and NASAspaceflight, shared photographs and short videos of the cryogenic proof tests, shown below. Testing is expected to continue throughout the month.

"One Of The Biggest Improvements": Elon Musk Fixes Starship Rocket After YouTuber's Query

NDTV by Bhavya Sukheja May 17, 2022

https://www.ndtv.com/world-news/one-of-the-biggest-improvements-elon-musk-fixes-starship-rocket-after-youtubers-query-2982535

Improvement to the new ship is to use excess gas from the Starship's main engines for manoeuvring thrusters instead of separate cold gas thrusters.

A YouTuber's intelligent question helped Elon Musk to make a vital change to a new SpaceX rocket.

Everyday Astronaut, a YouTuber with around 1.25 million subscribers, was first invited to SpaceX's Starbase facility at the end of last year. However, after being invited back earlier this month, Elon Musk revealed that a question the YouTuber had asked actually led to changes being made on one of the newest rockets.

One of the improvements to the new ship is to use excess gas from the Starship's main engines for manoeuvring thrusters instead of separate cold gas thrusters. This correction was made after Everyday Astronaut's query asked of Musk.

SpaceX Starship SN24 passes cryogenic proof test –Full-stack is 'only a few weeks away,' says Elon Musk

Tesmanian by Evelyn Janeidy Arevalo June 02, 2022

https://www.tesmanian.com/blogs/tesmanian-blog/sn24-testing

SpaceX aims to accomplish launching the first Starship to orbit this year. An orbital flight test will provide engineers with vital insight to advance Starship's development. The two-stage launch vehicle which consists of the spacecraft and the enormous Super Heavy rocket that is destined to become the world’s most powerful operational launch vehicle, right next to NASA's retired Saturn V rocket that launched Apollo astronauts to the Moon over half a century ago. NASA has awarded a contract to SpaceX to develop a lunar-optimized Starship Human Landing System (HLS) to return astronauts to the lunar surface by 2025.

Starship is actively under development since 2019, SpaceX has launched and landed the spacecraft multiple times but has never launched a Starship to orbit. The company planned to conduct the debut orbital flight attempt in 2020, however, the U.S. Federal Aviation Administration (FAA) delayed SpaceX’s plans due to the ongoing environmental assessment at the Starbase launch site in Boca Chica Beach, Texas. The assessment is expected to be completed by June 13th, after roughly 11 months. If the FAA approves, SpaceX will be able to apply for a spaceflight license to launch the first full-stack Starship/Super Heavy to orbit this year.

SpaceX plans to use the Super Heavy Booster 7 prototype to propel the Starship SN24 prototype to orbit. Engineers have been manufacturing and ground testing the vehicles to prepare for the orbital flight. The rocket will be equipped with 33 methane-fueled Raptor V2 engines capable of generating over 16 million pounds of thrust. On Tuesday, May 31st, SpaceX founder Elon Musk shared that engineers would fully-stack SN24 and Booster 7 soon. He said a full-stack is “only a few weeks away” and “all Raptor 2 engines needed for first orbital flight are complete & being installed,” he wrote via Twitter on May 31. Local Boca Chica residents have captured photos of the Raptor V2 engines arriving at the rocket factory for installation.

Elon Musk reveals 33 Raptor 2 engines on Super Heavy rocket that will power Starship

https://www.aroged.com/2022/06/13/elon-musk-reveals-33-raptor-2-engines-on-super-heavy-rocket-that-will-power-starship/



Aerospace company SpaceX is gradually approaching the first orbital test launch of the Starship, which will be conducted from a site in Boca Chica, Texas. This will happen after the US Federal Aviation Administration (FAA) completes an environmental review. In anticipation of this event, the head of SpaceX Elon Musk published An image showing 33 Raptor 2 engines mounted on the Super Heavy launch vehicle of the Starship system.

The message accompanying the picture says that each of the 33 Raptor 2 engines develops 230 metric tons of thrust. Previously, Musk also reported that the Raptor 2 developed a record pressure of 300 bar in the working chamber. Since SpaceX installed all 33 engines on the launch vehicle, this means that they have all been tested and the company’s engineers have not identified any problems.

The installation of the engines was the next step on the way to a full-fledged test of the rocket, during which the fuel and propulsion systems will be tested. Unlike other rockets that use 2-4 engines, Starship’s super-heavy system is significantly more complex. However, SpaceX has considerable experience in this, since it was Elon Musk’s company that was the first to create a reusable system, the first stage of which is equipped with 9 engines and is successfully used in multiple launches.

Elon Musk fathered two children last year with Shivon Zilis, a top executive at his artificial intelligence company Neuralink, new court documents show.

The world’s wealthiest man now has nine known children, including five children with his first wife, Justine Musk, and two with the singer Claire Boucher, known professionally as Grimes.

Court documents obtained by Insider and published on Wednesday showed that Elon Musk and Zilis filed a petition to change their twin babies’ names to “have their father’s last name and contain their mother’s last name as part of their middle name”.

The petition was filed in Austin, Texas, where the babies were born, and was approved by the judge. Zilis reportedly gave birth in November, weeks before Musk and Boucher had their second child via a surrogate.
