More on Venus:

"On 14 September 2020, a study published in Nature suggested that traces of
phosphine in Venus' atmosphere could be an indication of a biological process:
that is, of microbial alien life. If confirmed, such a finding could completely
change the way we think about the universe, which has us taking a serious look
at what it would take to get human explorers to Venus in the near future. This
article was originally published on 16 December 2014."


"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.

To put NASA’s High Altitude Venus Operational Concept (HAVOC) mission in
context, it helps to start thinking about exploring the atmosphere of Venus
instead of exploring the surface. “The vast majority of people, when they hear
the idea of going to Venus and exploring, think of the surface, where it’s hot
enough to melt lead and the pressure is the same as if you were almost a mile
underneath the ocean,” Jones says. “I think that not many people have gone and
looked at the relatively much more hospitable atmosphere and how you might
tackle operating there for a while.”"
