View Full Version : Rovers on mercury

Is it an idea to send rovers to mercury? Like the marsrovers(spirit and opportunity)? And let the rovers explore the surface on mercury,and takes a lot of pictures. The only problem is the Extreme sunheat and radiation but it must be (protected) rovers ,i think that will be a great step for our spaceexploration,because we have never landed on mercury. But i think that putting a man on mercury is a dangerous thing,because of the intense heat and radiation of the sun,because it is the planet in our solarsystem that is closest to the sun of all the 9 (maybe 10) planets. What do you think? If we ever will put humans on mercury,then we need heatproof and solarproof suits,i think a little bit different than the suits we have used for the apollo missions on the moon.

BepiColumbo (http://sci.esa.int/science-e/www/area/index.cfm?fareaid=30), the ESA mission to Mercury, was originally supposed to include a lander, but it was cut due to budget issues. A rover would be nice, but a lander would probably come first.

Humans would need very special suits to work on Mercury's surface, though I daresay if they do show up they will tend to work either on the night side or right on the edge between day and night, since producing suits capable of handling full daylight would be a challenge.

That would be the least interesting planet to visit anyways...

Well, you never know.
So far, we've not gone anywhere without ending up completely flabbergasted.

One issue with rovers is that the surface of mercury is significantly rougher than the surface of Mars. It is not an insurmountable obstacle, but would certainly require different designs than the existing rovers.

A rover would definitely need a sun shade of some kind, and probably well-insulated wheels--same deal for its underbelly. It could be solar-powered, though I'm inclined to think that even if it were nuclear, the long nights would make any rover / lander virtually useless without some powerful onboard spotlight.

Barring that, it looks like any long term will either have to pack a lot into a single Mercurian day, or face long alternating cycles of activity and inactivity. It would be an interesting mission to staff. :)

Why not just slap some IR cameras onto it for night use?

Mars rovers went there to check for evidence of life on mars. As far as we know no life can evolve on mercury so it holds very little interest.

Unlike Venus and Earth the planet Merucry has next to no atmosphere, so it has no greenhouse-effect meaning Mercury can be very hot at day but the nightside of Mercury gets cold, really cold. The nightside is really dark and things cool down very quick on the nighttime area, temperatures drop to a frozen -290 F or -180 C so I'm not sure how well even the best-of Infrared-Cam's would work here.

They went to look for past signs of water, actually (there have been no biology experiments on Mars missions since Viking), but the same thing holds - probably not much water on Mercury, either.
