Mars 2020
Collaboration Among SMD, HEOMD and STMD
Mars 2020 will seek signs of past life on Mars, collect and store a
set of soil and rock samples that could be returned to Earth in
the future, and test new technology to benefit future robotic and
human exploration of Mars.
HEOMD / SMD / STMD are jointly sponsoring investigations to
address high priority strategic knowledge gaps and technology
development objectives for Human Exploration
• Mars Entry, Descent and Landing Instrumentation (MEDLI) to
refine atmospheric entry models to inform future landing
system design
46
• Exploration technology payloads that make significant progress
towards filling at least one major Strategic Knowledge Gap.

What about the costs of a Human mission
to Mars?
• $1.5 trillion?!
