Welcome to the BABB, Flimshaw
This link gives a good description of the TV camera on the MESA.:

Thanks for all the info guys. Some good reading

I have another question though. How would you develop a spacesuit for unknown conditions? Would you base it on educated guesses or just make a suit that could withstand the worst environment?

Thanks for making me feel welcome.

Depends on the range of "unknown". Making a suit that would work both on Venus and Pluto would be a hard thing to achieve.
So, can you be a little more specific?

PS: BTW, in my first post I forgot my manners ops: Welcome to the BABB, Flimshaw.

I meant the conditions of the moon. How would we know what the environment etc. are like before we have landed there?

P.S. Don't worry about not welcoming me. I was just glad not to get flammed out of the forum

Well the moon was not completely unknown. We had sent probes there as well as a few manned missions that didn't land. The moon is the same distance from the sun so we know how much sunlight it receives and it is too small to have any appreciable atmosphere so we knew to expect a vacuum. I'm sure others can go into more detail but we really knew quite a bit about the environment before setting foot there.

The space environmental had been studied and was well understood before the moon landings. If one understands the environment of space, the conditions on the Moon can be accurately predicted. Furthermore, we successfully landed five probes on the Moon prior to Apollo.

The lunar environment was pretty well known, so it was no big problem to accommodate a worst-case design for the suit. I don't know how far the design was evolved when the first Surveyors landed and if they had to change something. There was a major change for the last three missions, mainly by adding a hip-joint as it was neccesary to sit down on the seats of the rover.

Make a visit to Karl Dodenhoff's Little Space Museum. It has a very good section on the suit.

On a sidenote, when the LM was designed, there was no good data on how strong the ground will be, so they used some pretty large pads. Later they knew that they were pretty oversized and it would have saved them some problems if they would have known this from the start. But then it was too late and any design change would have caused to much work, so the pads were left as they were.

Its actually relatively simple. There are really two basic conditions a space suit must provide: temperature and pressure. The moon is in a vacuum. A vacuum is a vacuum. They are all pretty much the same. Next is temperature - even without a probe on the moon, you can read temperature simply by looking at it in infrared: the color of the light is determined by temperature.

Now there are, of course, other issues: sunlight (face shield), mobility, communications, etc., but none of those issues are specific to being on the moon.

Hi kucharek

Armstrong tethered? Tell me more!
