\begin{abstract}
Tomorrow marks 5 years since the Curiosity rover's dramatic landing on
the red planet! The rover's Sample Analysis at Mars (SAM) instrument
suite onboard Curiosity is the most complicated instrument NASA has ever
sent to another planet. SAM is designed to measure the composition of
the atmosphere and solid samples inside Gale Crater on Mars, and help
scientists assess the habitability (could a certain place support life?)
of environments recorded in in rocks in Gale Crater. The SAM team has
made many amazing discoveries, including finding evidence of a habitable
environment -- a place that life (think tiny microorganisms, not
dinosaurs) could have survived if it had been in that spot on Mars,
millions of years ago. SAM also detected the first organics (building
blocks of life) on Mars, known to have originated on this planet. We're
a group of scientists and engineers from the SAM team, ready to answer
your questions about Mars and SAM. We'll be online from 1:00 to 2:00 pm
EST and we will sign our answers. Ask us anything! Paul Mahaffy, SAM
Principle Investigator, Director of Solar System Exploration Division,
NASA Goddard Space Flight Center Charles Malespin, SAM Deputy Principle
Investigator, NASA Goddard Space Flight Center Jen Stern, Planetary
Scientist, NASA Goddard Space Flight Center James Lewis, Postdoctoral
Fellow, NASA Goddard Space Flight Center Brad Sutter, Planetary
Scientist, NASA Johnson Space Flight Center Greg Flesch, Instrument
Engineer, NASA Jet Propulsion Laboratory Peter Martin, PhD student,
CalTech/NASA Jet Propulsion Laboratory Doug Archer, Planetary
Scientist/NASA Johnson Space Center We have now been on Mars for 5 years
- WOW. The first year after landing we actually played the Happy
Birthday song using our SSIT (solid sample inlet tube). You may find
this link interesting https://www.youtube.com/watch?v=uxVVgBAosqg EDIT
It has been great answering your questions, we are signing off now!%
