There’s no denying that there are many important issues facing humanity that need fixing. But solving these problems doesn’t depend on defunding space programs.
Was Mars home to microscopic life in the distant past?
An intriguing rock spotted by @NASAPersevere has qualities that fit the definition of a possible indicator of ancient life. But what did we find, and how will we know for sure? https://t.co/vMJScXhqYy
*Cronch* I ran over a rock and found crystals inside!
It's pure sulfur. (And no, it doesn’t smell.) Elemental sulfur is something we’ve never seen before on Mars. We don't know much about these yellow crystals yet, but my team is excited to investigate. https://t.co/Am07DuXpPX
Ethan Siegel's wonderful write up on our new measurement of the Cosmic Optical Background. Our conclusion in one line is:
The light we see is from the galaxies we counted, and in between them, darkness there, and nothing more...
We're preparing a mission to rendezvous with the asteroid #Apophis. ‘Ramses’ will be designed to accompany Apophis through its close and incredibly rare flyby of Earth in 2029.

Our #OSIRISREx mission went to asteroid Bennu to learn more about the early solar system. Early analyses of the returned sample reveal organic molecules and surprisingly, phosphates, which indicate that Bennu may have once been part of a wet world. https://t.co/MjmF8pUCCS
We have selected @SpaceX to develop and deliver the U.S. Deorbit Vehicle and prepare for a safe and responsible deorbit of the @Space_Station after the end of its operational life in 2030. Learn more: https://t.co/ogAhEazBpt
Moving in for a closer look! 🔎

Starship’s fourth flight test launched with ambitious goals, attempting to go farther than any previous test before and begin demonstrating capabilities central to return and reuse of Starship and Super Heavy.
The payload for this test was the data.

The @ESA_Euclid space telescope has found a nest of free-floating planets -- born alone, without a parent star. And just look where they are floating!

🌋 On Feb. 3, the #JunoMission captured two volcanic plumes rising above Jupiter's moon Io – either two vents from one giant volcano, or two volcanoes near each other. The team will be analyzing this against additional data from Juno and other missions to get a better understanding. See the latest at https://t.co/C6GNLxBVQT
Ingenuity was groundbreaking in two significant ways that will ripple through the culture of NASA and its exploration efforts for decades. Both of these impacts seem overwhelmingly positive for our efforts to divine the secrets of our Solar System.
