I think most Apollo missions left small memorials on the moon - to both fallen astronauts and cosmonauts. <br />(sorry I have no list)<br /><br />Mars the Columbia astronauts are memorialized on Mars. Not sure who else. <br /><br />(That's kind of amazing, and very sad- to think about those astronauts on Columbia - from that day they launched in January 2003 - less than a year later, a plaque bearing their names would be sitting on Mars, who could imagine that?)
The only memorials on Mars I know of are Soviet pennants that were placed on (at least) one of the Mars landers that reached the planet in 1971 (Mars 2 & 3), and a "microdot" on the Viking landers that is just a list of everyone who worked on the mission written in microscopic print.
I am wondering what craters on the moon are named after astronauts?<br /><br />There are alot of craters on the moon but do you have any idea which ones are named after astronauts aside From Armstrong,Aldrin and Collins?<br /><br />http://en.wikipedia.org/wiki/List_of_craters_on_the_Moon
Actually I am really curious now what features on the moon and mars are named after astronauts/cosmonauts. So far I have only found the Crews of Challenger and Columbia as well as the crew of Apollo 1. I thought there would be a bunch on the Moon
