I met Golombeck at a lecture on Mars Pathfinder in September of 1997 (note the date).
I asked him when he thought manned Mars missions would begin and if he preferred them
to robotic ones in terms of science return. He said that he did not want to see a manned
mission happen any time soon (though he knew they would happen eventually) and that
robots were both cheaper and more efficient ways to explore space.

I asked Steve Squyres and Jim Bell a similar question in 2003. They both said they
would like to see manned Mars missions, but that they thought they would be too
expensive to happen any time soon and were more than happy with robot probes.
Again, see the date.

No, I did not ask every JPL scientist, but I noted the general trend in attitude
before VSE. It was similar to the one in the days before Apollo actually started
flying to the Moon. Once it happened, a few scientists griped, but most realized
they would be getting ounces of lunar material from a few Soviet robot sample
return missions instead of the hundreds of pounds of lunar rock collected by the
astronauts if they didn't hop on board.
