There's a lot to process on Day 8 of the @NASAArtemis II mission. With Earth in view from Orion's windows, the astronauts are packing up and reflecting on their lunar journey.

Three days until launch! Yesterday our families arrived and we had some very welcome family time on the beach in the Florida sunshine. My daughter’s rocketry skills are on point! Let’s light this rocket! CREW-12!

That’s a wrap on the Q&A with Crew-12. Take a deep dive into the human health studies planned during their long-duration science mission aboard the @Space_Station, including adaption to low gravity and a new study examining subtle changes in blood flow. go.nasa.gov/4qqvJK2

ASGSR: Defend NASA Biological and Physical Sciences Division Science Call to Action
The President’s Budget Request was recently released and includes severe cuts to NASA’s Science Mission Directorate. More specifically, NASA’s Biological and Physical Sciences Division, which funds a lot of our research, faces a draconian 72% reduction in funds from $87.5M to just $25M. This budget includes only $13M for Physical Sciences research, $4M for Space Biology, and $4M for the CERISS initiative. More: <astrobiology.com/2025/06/asg…

Lol the arabidopsis database is paywalled and just using the website services docs points. Imagine if Genbank had a similar model. Wtaf? They cant possible have so much traffic that they need to charge $500+ for a handful of access tokens, right? What am I missing here?

The NASA Open Science Data Repository (expansion of @NASAGeneLab) has enabled biological & health discoveries helping humanity become multi-planetary by helping life thrive in deep space on Mars and 🌘 OSDR stores precious data anyone can use and analyze, plus a community of collaborative users anyone can join, and several public tools/trainings (including AI/ML) for space biology available 🧵

Laurie Leshin has led JPL through the fires, funding cuts, and has to deal with tightening DEI rules.
She was the FIRST JPL Director to secure 8 weeks paid leave for parents.
A fierce advocate for science and people.
Her leadership will be deeply missed.

Nobody is perfect, not even close. Stop berating yourself for that which cannot be attained. Focus instead on reasonable goals towards continued learning and growth. Push yourself, but not over a cliff.

They found that drought leads to stomatal closure, which in turn suppresses VOC emissions.
This altered VOC profile makes attracts potato tuber moths but repels T. chilonis, a beneficial parasitoid that controls the pest.
