Big thank you to Lara Waldrop of @ECEILLINOIS for the talk at SSL. Lara leads the Carruthers Geocorona Observatory. It will orbit the Sun to capture UV images of Earth’s exosphere. SSL built many of the instruments and will contribute to the research and operate the spacecraft.
Thank you to Aurora Guy @Vincent_Ledvina for stopping by @ucbssl to tell us about your efforts to engage citizen scientists and aurora chasers in space weather research.
America needs the strongest possible NASA, commercial space and university network to remain safe, growing, and inspiring. Space science underpins our national security, boosts local economies, develops new technologies/resources and reveals where we stand in the cosmos.
This radio telescope will soon be sent to the moon. 🚀🌕 With all major components complete, we've finished a critical project phase for LuSEE-Night, and the telescope is now undergoing final assembly. @ucbssl @BerkeleyLab @NASA @ENERGY bnl.gov/newsroom/news.…

We got confirmation: The NASA CubeSat PADRE is alive and all systems look good 📡🛰️📞🔊🔉
The Solar Polarization and Directivity X-Ray Experiment (PADRE), led by SSL, launched today. PADRE will measure polarization and directivity of hard X-rays emitted during solar flares with the aim of developing better prediction models for solar emission events.
PADRE CubeSat taking off 🚀✨💪🏻🛰️
John Bonnell, project physicist at SSL, describes @NASA's @TRACERSMission, led by @uiowa. TRACERS will study the magnetopause (the boundary between the Earth's magnetosphere and the solar wind) with the aim of better understanding space weather.
