QUESTION:
Are there any plans to grow vegetation using martian soil?

ANSWER from Mark Adler on July 6, 1997:
No, not yet.  Eventually we will be returning a small amount of Martian dirt
to Earth, and we could do a small experiment of that type here.  Of course,
we'd have to at least add water since there won't be any water in dirt from
Mars' non-polar regions.  Also we may find out from data collected overnight
(5-6 July 1997) by the Sojourner rover what may be lacking in the dirt for
plant growth, and what may be present in the dirt that would inhibit plant
growth.
