watched a few videos today, the first was about launching the ARES shuttles. after NASA said they would stop launching shuttles, its back to square one with old style shuttles, complete with parachuting back to earth.
the part that comes back to earth is shaped and designed to fall to earth in a certain way, with about a foot thick of material that's meant to burn up on re-entry.
mr pitt told us about a few students from HAHS who have moved on to this astronomical crap, including an andrew do guy who worked on the ARES projcets. he also told us of a 19 year old guy who designed the ways of travelling to mars.
the deal is, you gotta send satellites to where mars WILL be, not where it is currently, also it has to land in an orbit around mars so not to be pulled in or fall straight on the surface.
we talked abotu how coming into the earth (in a shuttle), you'd have to be at the right angle. if the angle was too steep, it would burn up too quickly and easily. if nto steep enough, the shuttle will head back in the opposite direciton, kind of like skipping a stone on a pond, but skipping the shuttle on the atmosphere of the earth? hahaha
also.. venus' orbit is faster than ours.. but we didnt finisht aht discussion about why

ReplyDeleteDo you mean that it travels faster or takes a shorter amount of time to orbit the sun
