can there be a system in the space shuttle which will enable the astronauts to eject out automatically during?

Answer 1

.... during launch? Theoretically, yes.

As violent as the Challenger explosion was, the crew cockpit was flung off intact. If the crew cockpit was outfitted with a parachute, any crewmembers surviving the accleration forces from the initial blast could also survive the descent.

There's a lot of engineering challenges that would have to be overcome. For one thing, whatever system designed to store and deploy the parachute would have to survive the initial blast. Secondly, the shuttle has already been designed and built. Adding a reasonably reliable parachute system after the fact is virtually impossible.

Designing a system for surviving during descent could conceivably be designed. The shuttle would have to be designed to disintegrate around the crew cockpit and leave the crew cockpit unharmed. That means a second layer of thermal insulation, plus a parachute system to keep the crew cockpit from plummeting into the ocean or ground as the Challenger cockpit did. It's not something that can be installed after the shuttle has been designed and built.

Additionally, adding the safety systems adds weight, meaning a more powerful launch system would need to be designed. That means designing a larger fuel tank or larger solid rocket boosters.

While both are theoretically possible, you'd basically be designing an entirely new shuttle and be pushing up against a limit where the new shuttle might be too expensive to ever launch.

Answer 2

It might have been technically possible to incorporate such a thing early in the design phase, but through most of its flight the shuttle is moving much too fast for such an ejection to be survivable. The shuttle is generally not a great design- the original idea was for a fully re-usable launch vehicle that could substantially reduce the cost of space missions, but owing to inadequate funding allocations NASA was forced to fall back on the current design, which was much less ambitious, is now over 30 years old and is frankly a big disappointment.

Answer 3

NASA's new lunar program does have a way for astronauts to abort a liftoff. They will not be using the space shuttle, though. In a complete overhaul of the vehicles that will be used in the future, NASA will be using the Ares rocket. It is similar to the original rockets used by NASA and the Apollo program. The astronauts will travel in the Orion crew exploration vehicle. There is a safety feature that will send the CEV off by itself to return to the surface if there is a problem during liftoff. These vehicles will be used to return to the Moon's surface and will carry astronauts to and from the ISS, as well as serving as an unmanned cargo transporter.

Here's a great website with some information about the Orion and Ares vehicles: http://www.nasa.gov/mission_pages/constellation/main/index.html

Answer 4

No it is not possible to do safely. At the very begining of the flight there are some things that can be done but after that it is just hang on until you get there and back.

Remember the columbia???? if they could have ejected they would have.

Anyone that gets in a space rocket must understand that it might be their last day.

Answer 5

the gap go back and forth at the same time as it replaced into nevertheless operating, landed in the global clone of a common airplane and the Astronauts walked down stairs clone of a common airplane. the gap go back and forth in no way left earth orbit. replaced into no longer designed to flow to the moon or different planets. in the course of launch on the Cape, the noise isn't that tremendous. in the course of landing mind-set the go back and forth does smash the sound barrier at the same time as it re-enters earths air, notwithstanding it really is so severe up, no consequences are felt on the floor. All area Shuttles were placed out of service. Too previous and too severe priced to keep operating.

Answer 6

No...they are travelling so quickly that just to strike the air outside the space shuttle would flatten them.

Answer 7

Since the previous events, yes the system is in place.

Answer 8

during launch? yes.

in orbit? possibly but not likely

on approach? yes (provided you are low enough where the heat that is generated by the atmospheric friction wont kill you)

Answer 9

I believe they can only separate from the SRB's and fuel tank, that may be enough

Answer 10

Yes, I think so, provided that you learn to finish your
