Europe has fixed on a concept for its next mission to land on the Red Planet.

It aims to send a single robot rover to the Martian surface along with another, stationary, science package.

Has anyone proposed a manned mission for the purpose of controlling one or more rovers from orbit but without attempting to land human beings on the surface? I'd think we'd be able to get a lot more out of the rovers if they were controlled from no more than a few light seconds distance.

I could imagine this working for Mars or Venus, and I'd think that the cost would be a lot less than a mission that aimed to put people on the surface, but I've never seen it discussed anywhere.

That is one of the weakest point of NASA's research fund programs which is to improve the capability of robots for unmanned explorations. We are still using Pentium III alike for MSL and MRO. That is still backward. No much work on the interface between smart sensors, computer and software. Now, the Japan is leading on that field. We might send the Asimo, Honda's Humanoid Robot. That robot can walk and salute as any human.

Excitement fills the theater as guests witness ASIMO maneuver through a home nvironment using its amazing mobility capabilities such as walking forward and backward, climbing and descending a flight of stairs and even dancing!


However, the objective of Asimo design is to imitate as close as possible to humanoide action. Later, there were others incorporations such as the reasoning to solve problems.

Actually the CPU's in most modern spacecraft are more like 1/10th the performance of a Pentium 3....and what's more, there's not much requirement for anything better.

Now - you could argue that it's cyclical - the need for more on orbit computing power has not arisen because people have programmed for what is available and that's tended to be 'enough'. Also - spacecraft are tending to become little centres for distributed computer, with each instrument having it's own processor dedicated to the aquisition, compression and storage of it's own data - it leaves the CPU of most spacecraft doing the comparatively simple task of attitude control, data management, and streaming stuff through to telecoms etc.

I'm sure if there were something 10x faster availabel for on orbit computing, it would be utilised...but the fact that such a processing system isn't in place perhaps suggests it isn't really that necessary.

You drop the bloated OS, the graphics and so forth, dedicate the use of your CPU to on orbit computing, and actually, the mathematics behind a spacecraft are comparatively simple.
