I wrote about what we'll see during Juno's year of Io flybys, and why the proposed IVO mission would tell us even more about Io planetary.org/articles/juno-…
Looks like Ingenuity saw Perseverance's tracks during its 40th flight on Jan. 19

Tidal forces can bulge the surface of Io up to 100 meters. On Earth, the biggest difference between low and high tide is 16 meters, and that's water, not a solid surface!
All of that stress makes Io the most volcanically active world in our solar system.

Good spacecraft, good mission, good people. Thanks LightSail 1 and 2, for letting me follow you around the past eight years. planetary.org/articles/light…

On Sept. 15, 2017, almost five years ago, @NASACassini plunged into Saturn's atmosphere.

NASA hopes to reduce the price of exploring Mars with a mission called ESCAPADE.
This week on @PlanRad, we talk to principal investigator Rob Lillis whose team at @UCBerkeley will send two probes to Mars in 2024 for less than $80 million.

Honored to have the cover story for the new issue of @exploreplanets The Planetary Report, and perfect timing too! My magazine arrived today, the day @NASAWebb launch date was announced. (Currently targeting Dec 18). Thanks to @jasonrdavis for the opportunity!

Liquid water under the Martian polar ice? Maybe not.
Jeffrey Plaut and Isaac Smith are among the researchers who have found that a form of clay may be a better explanation. They join us this week on @PlanRad to discuss their findings.

NASA: The data show that you are totally hard-core.
Asteroid Psyche: Are you making a joke about me being the core of a protoplanet or —?
NASA: Yes, but you also just give off that vibe.
Here's your guide to @NASA's @MissionToPsyche: planetary.org/space-missions…

Testing complete ✅
#NASAWebb has completed testing at @NorthropGrumman, demonstrating that it can survive its journey into space. Engineers are now preparing to ship Webb to its launch site of Kourou, French Guiana: go.nasa.gov/3gCAW0h
