Dale Arney and Chris Jones, from the Space Mission Analysis Branch of NASA’s Systems Analysis and Concepts Directorate at Langley Research Center, in Virginia, have been exploring that idea. Perhaps humans could ride through the upper atmosphere of Venus in a solar-powered airship. Arney and Jones propose that it may make sense to go to Venus before we ever send humans to Mars.</I></BLOCKQUOTE></FONT></TD></TR><TR bgcolor="#333333"><TD valign=top><FONT SIZE="2" FACE="sans-serif">Robert Pearlman</FONT></TD><TD><FONT SIZE="2" FACE="sans-serif">More information about the NASA's High Altitude Venus Operational Concept (HAVOC) mission can be found on the Space Mission Analysis Branch <A HREF="http://sacd.larc.nasa.gov/branches/space-mission-analysis-branch-smab/smab-projects/havoc/" TARGET=_blank>website</A>. <BLOCKQUOTE><I>The atmosphere of Venus is an exciting destination for both further scientific study and future human exploration.

A recent internal NASA study of a High Altitude Venus Operational Concept (HAVOC) led to the development of an evolutionary program for the exploration of Venus, with focus on the mission architecture and vehicle concept for a 30 day crewed mission into Venus's atmosphere. Key technical challenges for the mission include performing the aerocapture maneuvers at Venus and Earth, inserting and inflating the airship at Venus, and protecting the solar panels and structure from the sulfuric acid in the atmosphere.

With advances in technology and further refinement of the concept, missions to the Venusian atmosphere can expand humanity's future in space.
