Come meet the head of NASA’s Planetary Science Division, Dr. Lori Glaze. (Find out more about how her path to NASA started with a volcano, why it’s important for her to step out of her comfort zone, and her heavy metal claim to fame:

Along with a tiny, but mighty, team of NASA communications folks, she’s ready to answer your questions about the solar system, and the NASA spaceships and people who explore it… without a bunch of jargon. It’s not rocket science, it’s an AMA. Let’s go!
Participants will initial their answers:
– Dr. Lori S. Glaze, Director, NASA’s Planetary Science Division (LSG)
– Alana Johnson, NASA Senior Communications Specialist (AJ)
– Laurance Fauconnet, Public Engagement, Educational Technology Specialist, NASA’s Jet Propulsion Laboratory (LF)
– Jessica Stoller Conrad, Web Producer, NASA’s Space Place (JSC)
– Lyle Tavernier, Educational Technology Specialist, NASA’s Jet Propulsion Laboratory (LT)
– Brice Russ, NASA Social Media Reddit Lead (BR)
– Stephanie L. Smith, NASA Social Media Manager (SLS)
We’ll be answering questions from 3-4 p.m. ET (2000-2100 UTC) on March 8.

Most exoplanets discovered so far are exotic and hostile to life – “Hot Jupiters” so to speak, but – as I understand it – that’s only because such planets are the easiest to detect. They’re big and close to their stars so they can block more of their stars’ light.
With JWST, will we soon be able to detect Earth-mass planets in the habitable zones around Sun-like stars? Or would such planets still be too small / too washed out by the starlight for even JWST to detect? According to our best models, do we expect such planets to be common in our galaxy, or rare?
Even if JWST is sensitive enough to detect such planets, would any of its sensors be sensitive enough to tell the composition & thickness of their atmospheres?
What are the protocols for ensuring we’re not contaminating other celestial bodies with Earth junk when we send missions there? If we ever find evidence of life on another body, how can we be sure it’s not a false positive because some microbe hitched a ride on our ship? How does this change between crewed vs uncrewed missions, and how does it affect the decision of whether to send a crewed mission or a robot to achieve some task?
