Rockets, Racecars, and the Physics of Going Fast

When our Space Launch System (SLS) rocket launches the Artemis missions to the Moon, it can have a top speed of more than six miles per second. Rockets and racecars are designed with speed in mind to accomplish their missions—but there’s more to speed than just engines and fuel. Learn more about the physics of going fast:

Take a look under the hood, so to speak, of our SLS mega Moon rocket and you’ll find that each of its four RS-25 engines have high-pressure turbopumps that generate a combined 94,400 horsepower per engine. All that horsepower creates more than 2 million pounds of thrust to help launch our four Artemis astronauts inside the Orion spacecraft beyond Earth orbit and onward to the Moon. How does that horsepower compare to a racecar? World champion racecars can generate more than 1,000 horsepower as they speed around the track.

As these vehicles start their engines, a series of special machinery is moving and grooving inside those engines. Turbo engines in racecars work at up to 15,000 rotations per minute, aka rpm. The turbopumps on the RS-25 engines rotate at a staggering 37,000 rpm. SLS’s RS-25 engines will burn for approximately eight minutes, while racecar engines generally run for 1 ½-3 hours during a race.

To use that power effectively, both rockets and racecars are designed to slice through the air as efficiently as possible.

While rockets want to eliminate as much drag as possible, racecars carefully use the air they’re slicing through to keep them pinned to the track and speed around corners faster. This phenomenon is called downforce.

Steering these mighty machines is a delicate process that involves complex mechanics.

Most racecars use a rack-and-pinion system to convert the turn of a steering wheel to precisely point the front tires in the right direction. While SLS doesn’t have a steering wheel, its powerful engines and solid rocket boosters do have nozzles that gimbal, or move, to better direct the force of the thrust during launch and flight.

Racecar drivers and astronauts are laser focused, keeping their sights set on the destination. Pit crews and launch control teams both analyze data from numerous sensors and computers to guide them to the finish line. In the case of our mighty SLS rocket, its 212-foot-tall core stage has nearly 1,000 sensors to help fly, track, and guide the rocket on the right trajectory and at the right speed. That same data is relayed to launch teams on the ground in real time. Like SLS, world-champion racecars use hundreds of sensors to help drivers and teams manage the race and perform at peak levels.

Knowing how to best use, manage, and battle the physics of going fast, is critical in that final lap. You can learn more about rockets and racecars here.

let me talk about SpaceX and rockets for a second

because while I don't give a flying fuck about musk

yesterday's (20/04/2023) launch was a succes. The point was to get it in the air, anything more was extra. It was a test flight. Every rocket goes through this process.

SpaceX is not bad at making rockets, there are a lot of very skilled scientists involved and rockets are constantly being reused etc. technology has been rapidly improving this field.

This is new technology and it is being tested. As I have said before, this happens and has happened for every rocket. With NASA, with Rocketlab with SpaceX, any company you can think of.

The scientists now have a lot of data they can use to improve the rocket where things went wrong.

This was a test flight, nothing was on board, this is a testing phase and this is new development. This was the first time that the full stack was tested in flight. I am speaking for the scientists here because they are the actual key to this. They've (scientists in this field in general) made some incredible forward steps in the last years.

It's probable that the explosion was planned to some extent and likely that it was absolutely expected to happen.

Yes you can laugh at the explosion, yes it looks hilarious I can appreciate the memes a lot please continue.

But do realise that this did not go wrong and this is a positive for the scientists that work on it.

#spacex #science #rockets #space #starship #scientists #because no one seems to get it #this is a rocket in testing phase #and i am not praising musk #i hate the man

SpaceX Launches Starship Rocket Into Space on 3rd Test Flight

SpaceX's Starship megarocket, the world's largest and most powerful rocket, reached orbital speed for the first time Thursday in a historic third test flight from South Texas.

Hundreds of Spring Break spectators, rocket launch chasers and SpaceX fans gathered along the southern shores of South Padre Island and surrounding areas to witness the third test flight of the biggest rocket ever built. About 5 miles (8 kilometers) south of the crowds, SpaceX's massive Starship vehicle lifted off this morning (March 14) at 9:25 a.m. EDT (1325 GMT) from the company's manufacturing and test launch facilities near Boca Chica Beach.

"Starship reached orbital velocity," SpaceX founder Elon Musk announced on X (formerly Twitter) after liftoff. "Congratulations SpaceX team!!" The launch occurred on the 22nd anniversary of SpaceX's founding in 2002, the company said.

Neither the Starship vehicle nor its Super Heavy booster survived all the way through to their intended splashdown, but SpaceX officials said the test flight achieved several of its key goals during the flight.

"Caught: Party Miku | Pac | Chip | Leddy"

Super lucky!

Chip belongs to @trinkerichi

Leddy belongs to @akfamilyhome

I made a few more of these to iron out some of the kinks in the base, namely having a mirrored version and offering a "doll" and "plush" version of the base. They're honestly not *that* different, but for reference, Kun3h0, Pac, and Chip are using the "doll" base while Miku and Leddy are using the "plush" base.

Speaking of characters I've never drawn before, since I don't have that many OCs to test with, I decided to draw some fellas that I've been wanting to draw for a while now, but just haven't had a good opportunity to. So, two birds, one stone~

Def check out both of those creators if you have some time~

solaris was crazy for not testing the rocket chair before she installed it into the madrid facility btw. zor could have literally blown up. did they know that she didn't test it?? i don't know whether it's funnier to assume that she's so confident in her ability that she didn't feel the need to test it for lethal malfunctions, or if zor getting in some horrible pyrotechnics incident was her fantasy from the start.

#ieytd #commander solaris #or secret third option: zor stretched her so thin she did not physically have the time to properly test it #which. admittedly. seems most plausible when you consider the fact she seems disappointed that SHE couldn't have tested it #which. in itself flows back into theory one. because i don't think she would test her rocket chair if she thought it would have blowed up #still its CRAZY that she got away with that shit. ieytd could have been one game #zor could have been horribly mangled in some freak chair incident and that would have been it no more video games

“Fuck Animal Testing” by @manueljiniesta_art Digital art with @procreate #fanart of #rocketraccoon from @guardiansofthegalaxy Esta ilustración va dedicada a todas las Lyllas, las Floor (Suelo), Teefs (Dientes) y por supuesto a todos los Rockets. Os merecéis un mundo mejor y pelearemos por conseguirlo. Para erradicar a todos los Altos Evolucionadores que no quieren hacer cosas perfectas, sino simplemente odian las cosas tal y como son.
