We can't know anything right now. This is when smart people are silent and wait.

Man am I on a massive space video binge. The past few days have really re-ignited my interest in space. thank you for playing a part in that bro!!

Some interesting history that you didn't cover here is that the Space Shuttle orbiters were originally supposed to have a LES of their own and that design was kept well up until when the vehicle was to go into production, but like other features it was dropped to save weight, complexity, and most importantly money. The system was referred to as the Abort Solid Rocket Motors or ASRM. It could be described as a pusher-type since it was comprised of twin rockets attached to the sides of the orbiter's aft fuselage and when fired would carry the orbiter away from a malfunctioning stack. The ASRM's weight was initially considered acceptable since when the Shuttle reached a point where it was no longer usable, it could be fired off, the thrust boosting the stack and countering the dead weight, then jettisoned. So what's the big deal? Aside from cost there was another problem that kept rearing its ugly head; an abort scenario where the ASRM was used invoked heavy stresses on the orbiter airframe and so to keep the vehicle from breaking apart due to the aerodynamic load, the frame had to be beefed up structurally to the tune of a whopping 9 metric tons! In addition, this would not save the orbiter or its crew and payload in the advent of an exploding SSME, so its usefulness was limited to failures of the ET or SRBs. Since NASA was under a great deal of pressure to make the Shuttle meet the DoD, CIA, and NRO's payload requirement of 65,000 lbs (29 tons) to LEO, and with costs for the program rising, ASRM was deleted from the design. Skip over two decades later and the design of the HL-20 lifting body that was the inspiration for SNC's Dream Chaser was also going to use a pusher type abort system. However this was a separate system not directly integrated into the craft and was a part of the cone-shaped launch vehicle adapter. The crewed variant of Dream Chaser, HL-20's successor, uses an integrated pusher system that also doubles as the orbital maneuvering system. Cargo Dream Chaser could in theory use this, but being stuck under a fairing makes its use impossible.

PROPULSIVE LANDING by SpaceX: My guess is that P-L is their long term goal and what happens in short run (i.e. parachutes) is just whatever it takes to keep NASA happy without compromising what they believe to be the best ultimate path.

@HiyuMarten

5 жыл бұрын

There are a couple issues with propulsive landing such a capsule: 1. It's important to have a central centre of mass when the engines are active, but during reentry, the opposite is true - having a controllable, offset centre of mass is required to steer the vehicle during its unpowered descent. 2. Is it worth the development cost? It's clear from some renders and talks that SpaceX intended to scale up Crew Dragon's landing system for use with BFR (later Starship), but when Starship's reentry profile changed to an improved design, developing it for Crew Dragon wouldn't have as much R&D benefit anymore. Development on Starship is now in full swing, so you're right that propulsively landing crew is their goal - it's just that it's shifted to their new vehicle. That said, it's been hinted at by Elon that Crew Dragon is still capable of propulsive landing in the astronomically rare event that all of its parachutes fail.

@DairyLife

5 жыл бұрын

I'm not sure that NASA (and probably SpaceX's enigneers) are incorrect in being circumspect about Crew Dragon's propulsive landing, since it relies on 8 engines and the landing legs properly operating after being subjected to a full flight regimen. How many of those can fail (and in what configuration)? And is there enough time to deploy backup parachutes if there is a failure? If a skycrane crashes landing a rover on mars because of an engine failure, it's an expensive embarrassment . If a capsule with a full crew crashes because of an engine failure, it's a horrific tragedy.

NASA wanted additional verification that it'd be safe to have holes in the heat shield for the landing legs to pop out of.

(Even if your cap is experiencing a Boeing angle of attack issue along with a yaw trim misalignment.. :p j/k) Seriously, nice to hear some level headed discussion of why Engineers do what they do and less "OMG it blew up, huge setback to program". *Pats your back - Well done.

Awesome video. Really well explained and your presentation is enjoyable to watch. One question: is your left eye glass?

12:47 but there are already solid rocket motors on the iss,the soyuz capsule uses solid rocket motors just a second before they touch down

I love the new intro. It may have been around for awhile but it's the first time I’ve seen it.

These emergency thingy are useless... Just revert the flight, right? It works in ksp...

Great video thanks so much! After the SpaceX anomaly I had questions about why they were using the hypergolic fuels and this type of abort system. Your video certainly answered all of my questions. Thanks again keep up the great work up

i’ve been recommended so many space videos since the dragon capsule docked with the iss

Towers used solid rocket motor fuel, less chance of explosions with a non-volatile liquid fuel. They pondered that question back in the day cuz that system has to work "first time, every time, all the time",... "Failure", as they used to say in NASA, in the 1960's, "was Not an Option"!

Houston We are screwed Again

A point on hypergolic fuel engines - the Apollo 13 Lunar Module throttleable descent stage engine, designed entirely for landing on the Moon, was effectively adapted to get the three astronauts home by doing a timed burn to return to Earth. I'm not sure any other rocket engine category would have been capable of such adaptability.

2 videos in... already subscribed

Tim, that was just excellent. Very well done.

2:50 Man can you please do a video on China and India's Crew vehicles and the rockets they are gonna be using for their upcoming manned missions to LEO?

Your Knowledge of engineering has definitely improved, I remember in your early videos You were dodging a lot of key terms. But now the Quality and depth of content is good. Keep it up. Keep it Engineeringy. Remember most people watching this type of stuff are probably into science.

@D.O.A. "I love the orange suit" The suit itself is great. It was the combination of the way hoses were left dangling and the way the information was presented in one of his early videos that turned me off. I may well have been too harsh and quick with my judgement.

0:51 "liquid rocket motors" 😄

Do we know the parameters of the escape systems such as the velocity required to separate the capsule from the booster and what the system start up time requirements for time of anomaly to escape system sequence start up?

@Everyday Astronaut Tim, make a video on all the calculations the Falcon 9 boosters do to land! It would be very helpful if other people want to make a reusable booster.

Last October when Soyuz MS-10 accident happened escape tower was already ditched and crew was saved using SRMs built into fairing

"Abort to orbit" Sounds badass

In a pusher style abort scenario (Starliner or Dragon) do the abort engines actually utilize thrust differential to steer? Are the crew module RCS thrusters used at all for additional guidance?

is it possible to have the dragon capsule use parachutes above land but when they get very close to the ground turn on the engines at low thrust so the capsule has a soft landing we can see the astronauts in the space x space suit and it will be easier to certify for human preflight and for the landing as it uses some parachutes.

I really appreciate the insightful info you have provided on these crewed space capsules, keep up the good work Erdayastronaut....

Tim, Dragon 2 uses helium tanks to pressurise the super draco system. The hypergolics are not self-pressurised.

That was a great explanation; If you could make a video on mechanism of staging process that would be greatly helpfull

The metaphor being used is the same either way the only difference being the implied relationship between the questioner and the respondent.

Tim you should check out the video footage from Reds Rhetoric and Astronomy Live. They are the best amateur rocket filmers there is.

I would like to see SpaceX later on revisit and try to work on landing the dragon capsule. It would be a another frist.

Hey, really loved this video... 3:48 the inside of the Blue Origin capsule 11:20 the "Orion" solid rocket attitude control test.

The great thing about this is because now I know that the Starliner has an abort system

Anyone know if the crew dragon flight computer will attempt a propulsive landing if it detects that the parachute failed to deploy? Or does the new design no longer have the fuel for propulsive landings?

but isn't the whole point of propulsive landing to enable soft landing on land. Because landing in water (propulsve or not) exposes capsule to salty water and damages it. Propulsive landing in water wouldn't fix that. By using parachutes they are coasting the capsule in water, so landing speed is not such a problem, water is. Anything that enters the sea is extremely hard to refurbish for another flight, moreso for human flight.

I think they will, I mean the effort is rather small to configure the thrusters for that and I think the have like fuel to run theses thrusters a good amount of time. brachypelmasmith, I think you don't get the original question. It was can the flight abort systems original landing capabilities be used to emergency land when the parachutes fail. If that happens, the landing on land or the reusablity of the capsule is irrelevant. The only important thing then is to land the crew save.

@brachypelmasmith

in that case, I dont know. I am sad that NASA forbade them to go with that propulsive landing, so m sceptical about them proceeding with implementation of that system with all the hussle with approval/licencing process by NASA. It seems like a waste to design something that you aren't supposed to have or use.

Question, I didn't have a question. You put the question in my head but.... nice channel EA :) very solid sharp images and vids not cutting them dozens of times because they can't remember a single line to say it in once.

Love your channel man. Learning lots of cool stuff.

14:28 - except now we are seeing humans in the dragon capsule!!

Not a comment on the video, cool as it was, this is about something in the background ... I first knew about MovaGlobes from one of your videos. You had several lined up and a quick image, pointing to them stating Mova Globes. (MovaGlobes.com btw) I now have one of them spinning upon my cubicle at work. Even though I know how they work, when people ask about it's operation, I say "Magic."

BRAVO, TIM. Just a BRILLIANT video! I'm so ancient (67) that I remember the news bulletin announcing that the Soviets had put a man in space. I've been a rabid space junkie since that day, (I know my stuff) but I'll tell you... your video just taught me four things I never knew! Guess I'm not as smart as I thought I was...
