msl sky crane?
Hi,
I've been searching for video's and information on testing of the msl sky crane system. Apparently I've been looking in all the wrong places because I have found nothing but nice pictures about how it should work on mars. Turning to the wisdom of the group here. Have test articles been built and tested? Are video's and information available? TIA Roland |

*snip* Have test articles been built and tested? Are video's and information available? TIA Roland There's a basic drop test of the teather system: http://www.universetoday.com/82679/v...ars-rovers-sky -crane-landing-system/ It is typical that everything was tested in component and major assembly levels, but as far as the total system... I think that's simulation. Each of the major bits except the teather have been used at some point, just adding the teather and not landing the lander is a new twist. The retro-fire and lower bit seeks to remove many problem modes encountered with heavier craft in a direct landing. Releasing the chutes early to have a higher probability of not landing on the craft and the skycrane should have released the vehicle before the chutes could foul the skycrane. Dust on landing is greatly reduced and the vehicle acts like a big curb feeler, in that the weight on the wheels will confirm actual touchdown. Just, flying the skycrane away seems a little vague to me. Much prefer a phrase like: 200 meters South before cutting thrust. RB |

I hope I am wrong.... Nasa does NOT need another high profile failure!!!!! ======================================= MODERATOR'S COMMENT: Allowing, but minimally Very little actual technical content in reply. -GdM |
