I think now I understand the whole thing. Orion is made for orbiting the moon and earth entry not moon entry. And this one is supossed to be better than the one they had on the apollo mission ofcourse.
c'mon... such long stairs for the lunar lander? do they really have to put it at the top of the lunar lander? nobody ever asks what happens if an astronaut falls from the top of those stairs? back in the 70's they were worried that the suit might fail if the astronaut just tips and falls from the ground level. they could just remove the ladder and provide the astronauts with some bungee cord. It would be just as safe as climbing down that long ladder in a bulky suit...
i am not an expert, but i know that in the apollo program the original design of the LEM had no ladder but a rope system. The astronaut could get down but not up again:) Remember astronauts will train many times to walk on the ladder. It will be quite safe. Astronauts know how to keep their cool you know. And i think stairs are more convenient when it comes to moving equipment and getting rocks and samples and such in to the Altair (new LEM).
I am not disputing the ability of astronauts to keep cool. I know they have a lot of training, but you know, s**t happens sometimes... and I can give you several examples... watch the NASA videos with them on the moon and you'll notice that they fell several times; just a few months ago Stephanishin-Piper lost the grip to her tool box during an EVA to ISS. And at the height of the ladder shown in these animations, you only need one small incident and it may turn into disaster...
Keep in mind that the last time were on the moon was 36 years ago, not 40 and the reason to return is not just to "do it again." We know so much more now about long-duration, manned spaceflight. This next step involves longer stays which allow for a permanent base from which future missions to Mars can be staged, astronomical observations and the possible mining of helium and other mineral products.
Airbags simulate water splashdown are retrieval is TONS cheaper!

ok, about 40 years ago. All i did was to show the tests we have done and in the near future. But youre right ofcourse.

Hey, no problem. It's a fantastic video. Very inspiring to see all these elements pulled together. Thanks.

what if they land on rocks?
culture101 3 years ago
yeah, it would problably be more safe with airbags. Because of rocks and slopes
joachim2464 3 years ago
why don't they have a landing gear on orion instead of just those airbags ?
culture101 3 years ago
i think landing bags save more space maybe
