FYI Greg Autry @GregWAutry at @UCF @UCFBusiness @ucfspacebiz really wants to be the next @NASA Administrator. With #Project2025 & the #ScheduleF loyalty test how many people at #NASA will be defined in the same way? Is this any way to explore space? No. https://t.co/vIZTlkXMTS

I last launched from Pad 39A in 2009 aboard Space Shuttle Atlantis in 2009 to @NASAHubble. Today a mission I helped to start, the @EuropaClipper, departs for Jupiter and its rendezvous with #Europa. Go Clipper! Watch here https://t.co/rnCSFtJE83

[John Grunsfeld @SciAstro]

Are we alone in the Universe? Today is game time for the Europa Clipper which can look for signs of life and habitability on this icy moon of Jupiter. Launch from pad 39A at Kennedy Space Center is an hour away. Go Clipper! https://t.co/aCoq3B8UDB

@StephenAtHome please join us tomorrow night at https://t.co/6vo4pDI5vD We have a long list of great Star Trek and space luminaries supporting science, exploration and STEM. That will get under Trumps skin as well.

[Headquarters @HQNewsNow]

.@StephenAtHome: The fact that Kamala Harris is drawing bigger crowds than Donald Trump is really getting under his skin. All this happiness is really hard on a man who is incapable of joy

[Dr. Graham Lau @cosmobiologist]

Many of us in the space industry, from scientists and engineers, astronauts and Star Trek actors, and more will be speaking tomorrow night for @space4harris.

Join me along with @BillNye, @RobertPicardo, @TheGalacticGal, @Laur_Ly, and others as we share our vision for where space exploration and realms of study (like astrobiology) can go with @KamalaHarris and @Tim_Walz as our next U.S. President and VP.
