Zeitgeist kicked-off the first of several rideshares Exolaunch will manifest on Falcon 9 as part of a multi-launch agreement with SpaceX. On this mission, Exolaunch provided deployment, mission management and integration services to the German Aerospace Center (DLR), Dresden Technical University, ICEYE, NanoAvionics and other commercial companies for IoT, Earth observation and scientific applications.

“This Zeitgeist mission set a new standard for rideshare launches and not only was a successful demonstration of Exolaunch’s capabilities, but also paved the way for smallsat developers from around the world to participate in SpaceX’s SmallSat Rideshare Program,” said Jeanne Medvedeva, Vice President of Launch Services at Exolaunch. “We are proud to be working with so many of the world’s leading satellite and technology companies to advance the NewSpace industry, and we are already looking ahead to additional Falcon 9 launches later this year.”

Zeitgeist was Exolaunch’s 12th rideshare mission. As with previous launches, Exolaunch utilized its proprietary flight-proven separation systems – CarboNIX, the next generation shock-free separation system for microsatellites, upgraded modifications of EXOpod cubesat deployers, as well as its EXObox sequencers to flawlessly deploy its customers’ satellites into the target orbit. With this launch, Exolaunch has flown 140 smallsats on multiple launch vehicles.

Exolaunch’s manifest on the Transporter-1 mission includes the following satellites:
