  • We had a blast at the 40th Space Symposium last week! There's nothing more energizing than talking about the future of the space industry with passionate innovators and explorers like Douglas Hurley, Bob Behnken, David Caponio, Molly McCormick, Matthew Gialich, Andrew Duggleby, Julia Black, Anna Menon, & Sarah Gillis. From developing next-gen propulsion systems to operating commercial space stations, one main theme stood out across these discussions: there's a growing need for secure cloud-based tools like Epsilon3 that help teams build, test, and execute faster and more efficiently than their competitors.

    CEO & Co-Founder @ Epsilon3 (YC S21) | 🚀 Optimizing processes for aerospace and beyond!

    Suni is 100% a badass. I first got to work with her in 2009 as she trained with Aki Hoshide for the first Dragon approach to the ISS. She was the first astronaut I got to know, and when she was one of the 4 astronauts I got to work with as part of the commercial crew development program. We were all elated to work with her, and now It's kind of poetic to see this journey come full circle after flying Doug and Bob on the first Crew Dragon mission, to now seeing my SpaceX family bring Suni home with the rest of the crew from a long-duration stay on the ISS. (I'd share a pic, but I don't want to get in trouble.)

    𝗦𝗵𝗲 𝗵𝗮𝗱 𝗶𝘁 𝗮𝗹𝗹 𝗮𝗹𝗼𝗻𝗴! 👩🏼🚀 👊🏼 Poor, Sunita Williams, 59 years old, was "stranded" in space for 9 months... (Along her fellow astronaut, Butch Wilmore.) -- 𝙔𝙚𝙖𝙝, 𝙧𝙞𝙜𝙝𝙩! Suni Williams, is a force of nature! Suni Williams flew combat missions as a Navy pilot. Over 3,000 flight hours in 30 different aircraft. She ranks among the most experienced. She walked in space nine times, spending 62+ hours in spacewalks (current record-holder for most hours by a woman and 4th overall). She ran a full, four-hour marathon 𝗶𝗻 𝗼𝗿𝗯𝗶𝘁 in 2007, the first person ever to do it. (Yes, while the ISS circled Earth at some 17,500 miles (28,163 km) per hour.) She completed a triathlon in space too, in 2012: biking, running without gravity, and swimming (strapped herself to the Advanced Resistive Exercise Device (ARED), which uses weights to imitate water resistance while swimming through anti-gravity.) In 2024, she flew Starliner’s test flight, the first woman to pilot a new spacecraft. Nine months in space, she returned safely to Earth yesterday, March 18, 2025. Sunita is a force of nature, an inspiring story and individual, and a role model of a human being. Welcome home, Suni! You inspire us all to aim higher. (BTW, they were never stranded on the space station. And their 280-day stay is now the sixth-longest mission in NASA history - so no, not the longest by far.) An emphasis on this International Women's History month, Suni has her name marked in the books of #InspiringWomen! [Additionally, edit: Suny and Butch are also the only two astronauts to have flown aboard four different spacecraft: ✨ NASA's Space Shuttle ✨ Roscosmos' Soyuz ✨ Boeing Starliner ✨ SpaceX Dragon A rare club of two! Here’s their incredible flight history: 🚀 Suni Williams' missions: Space Shuttle – STS-116 (2006) Soyuz – TMA-05M (2012) Boeing Starliner – Crew Flight Test (2024) SpaceX Dragon – Crew-9 (2024) 🚀 Butch Wilmore's missions: Space Shuttle – STS-129 (2009) Soyuz – TMA-14M (2014) Boeing Starliner – Crew Flight Test (2024) SpaceX Dragon – Crew-9 (2024)] (Incredible info in the 'aditionally, edit', thanks to Bettina Inclán for that.) #IWD25 #WomenHistoryMonth #WomeninAviation

    Welcome home, Crew-9 NASA Astronauts Nick Hague, Suni Williams, Butch Wilmore, and cosmonaut Aleksandr Gorbunov splashed down off the coast of Florida at 5:57 p.m. EDT (2127 UTC) on March 18, concluding their scientific mission to the International Space Station. Crew-9 returned to Earth in SpaceX's Dragon Freedom spacecraft, which arrived at the station with Hague and Gorbunov in September 2024. Get the details on NASA's SpaceX Crew-9 mission and today's crew return: https://lnkd.in/epVbnwnk

    🤠 HOWDY! Our Q1 company retreat was a real hoot! After a stellar engineering hackathon, some amazing BBQ, and visiting a few local customers, we two-stepped down to opening night of the Houston Rodeo. This really is the best team in the world! Shoutout to Axiom Space, Venus Aerospace, and NASA - National Aeronautics and Space Administration for allowing us to see your incredible facilities. 🚀 🛰️ 🧑🚀 #hiring
