With sadness and gratitude, we honor George F. Smoot III—Berkeley Lab scientist since 1974 and 2006 Nobel Laureate in Physics—who has passed away at 80. His “baby picture” of the universe changed cosmology. https://elements.lbl.gov/news/honoring-the-legacy-of-george-smoot/ @nobelprize.bsky.social

The Carruthers mission and SSL were featured by KQED. Of the mission, our director Lindy Elkins-Tanton said, “Our big strength over time has been space weather...How does it affect our Earth’s atmosphere?... And that’s exactly what we’re going to be looking at." www.kqed.org/science/1998...

Scenes from our Mission Operations Center during launch of NASA's Carruthers, IMAP and SWFO-L1 on Sept 24. SSL operates Carruthers, built the instrumentation and contributes to the science. We also built an instrument for SWFO-L1 and lead an experiment on IMAP.

NASA's Carruthers mission launched this morning and is communicating with the Mission Operations Center at the @UCBerkeley Space Sciences Laboratory. Read more 👇 ssl.berkeley.edu/nasas-carrut...

Carruthers and ESCAPADE were featured in this @berkeleyside.org story on SSL's many contributions to space science and exploration.

It's a big week here at SSL. We built instruments for all three of the spacecraft that are scheduled to launch this week and expand our understanding of harmful space weather (IMAP, SWFO-L1 and Carruthers). www.nasa.gov/news-release...

Space science benefits every American. University space science programs are part of a vast aerospace economy that boosts local economies in every state in the country. #SpeakUp4Science #StandUpForUC

Space science is important for all Americans. Private aerospace ventures benefit immensely from the training pipeline made possible by university space science programs. #SpeakUp4Science

NASA's PADRE mission, led and built by SSL, measures X-rays emitted by solar flares at a fraction of the cost of previous missions. Its launch marks 45 years of SSL missions aimed at understanding the Sun and harmful space weather. #SpeakUp4Science www.ssl.berkeley.edu/padre-aims-t...

Big thank you to Lara Waldrop 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.

Our next #MFAUM25 speaker is Zack Gainsforth from the UC Berkeley Soace Sciences Laboratory, telling us about their work at the Foundry studying samples from the OSIRIS-REX mission to the asteroid Bennu! @ucbssl.bsky.social @ucberkeleyofficial.bsky.social

Thank you to "Aurora Guy" @vincentledvina.bsky.social for stopping by @ucbssl.bsky.social 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.

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.

John Bonnell, project physicist at SSL, describes NASA's TRACERS Mission, which will study the magnetopause (the boundary between the Earth's magnetosphere and the solar wind) with the aim of better understanding space weather.

Join SSL researcher and mission specialist Martin Sirk for an observational astronomy class far from city lights in the Sierra Nevada this summer. sierra.sfsu.edu/astr-216-pra...

Congratulations to former SSL undergrad Corina Dunn for being a finalist for the 2025 University Medal! Corina worked with SSL from 2022-2024. news.berkeley.edu/2025/05/08/i...

Big thanks to @edwinkite.bsky.social whose talk on prospects for terraforming Mars filled our conference room and elicited lively discussion.

SSL's designate director, Lindy Elkins-Tanton, discusses her research, leadership style and NASA's Psyche mission.

Planetary scientist Lindy Elkins-Tanton heads to UC Berkeley to lead the Space Sciences Laboratory, effective July 1. Welcome, Lindy! news.berkeley.edu/2025/05/06/p...

Our amazing undergraduate interns staffed SSL's table at Cal Day on Saturday, April 19th. They talked up SSL's undergraduate opportunities with admitted students and parents who posed for selfies with our out-of-this-world photo accessories.

The Auroral Acceleration Symposium in Honor of Charles W. (Chuck) Carlson wrapped up on Thursday, April 10th. The event included 24 talks on auroral investigations.

John Tomsick, research scientist at SSL, explains how Compton telescopes make gamma-ray images of the sky. Tomsick is principal investigator on NASA’s Compton Spectrometer and Imager (COSI) mission which hopes to learn more about element formation and antimatter at the center of our galaxy.

John Tomsick, research scientist at SSL, discusses gamma-ray bursts. Tomsick is principal investigator on NASA’s Compton Spectrometer and Imager (COSI) mission. COSI will search the skies for gamma-rays in hopes of learning more about black holes and neutron stars.

John Tomsick, research scientist at the Space Sciences Laboratory and principal investigator on NASA’s Compton Spectrometer and Imager (COSI) mission, discusses the mysterious fountain of antimatter at the center of our galaxy. COSI will search for gamma-rays in hopes of solving the mystery.

NASA’s SPHEREx space telescope launched on Tuesday. The spacecraft, built by @caltech.edu and NASA JPL includes an instrument control electronics box designed and built by the SSL.
