SUP?! Happy World Space Week! Special shout out to friends & colleagues at the 2026 @iafastro IAC. Sorry I wasn't able to attend the 4/6am committee meetings, but at least I attended a board meeting today. Follow @WorldSpaceWeek#WorldSpaceWeek and find events near you.
On Oct. 31, 1936, a group of Caltech students and enthusiasts began rocket propulsion tests in Arroyo Seco, north of Pasadena, CA.
Their work 90 years ago marked the beginning of @NASAJPL, now a vital part of NASA's exploration of the solar system and beyond. Happy 90th JPL!!
