The successful rideshare mission brings the total count of satellites deployed by Rocket Lab to 104

LONG BEACH, Calif.--(BUSINESS WIRE)--$VACQ--Rocket Lab, a leading launch provider and space systems company, has successfully launched its 19th Electron mission and deployed six spacecraft to orbit for a range of government and commercial customers. The mission, named �They Go Up So Fast,� also deployed Rocket Lab�s latest in-house manufactured Photon spacecraft to build flight heritage ahead of the upcoming CAPSTONE mission to the Moon for NASA.

The mission launched from Rocket Lab Launch Complex 1 on New Zealand�s Mahia Peninsula at 22:30, March 22, 2021 UTC, successfully deploying an Earth-observation satellite for BlackSky Global through Spaceflight Inc; two Internet of Things (IoT) nanosatellites for Australian commercial operators Fleet Space and Myriota; a test satellite built by the University of New South Wales (UNSW) Canberra Space in collaboration with the Royal Australian Air Force; a weather monitoring CubeSat for Care Weather Technologies; and a technology demonstrator for the U.S. Army�s Space and Missile Defense Command (SMDC). The mission took the total number of satellites deployed to orbit by Rocket Lab to 104.

After Electron successfully launched to an initial 550km circular orbit, the rocket�s integrated space tug or Kick Stage deployed its first five satellites to their individual orbits. The Kick Stage�s Curie engine was then reignited to lower its altitude and deploy the final small satellite to a 450km circular orbit. With its relightable Curie engine, the Kick Stage is unique in its capability to deploy multiple satellites to different orbits on the same small launch vehicle.

Following the deployment of the final customer payload on this mission the Kick Stage was reconfigured to Photon, Rocket Lab�s in-house built spacecraft. Photon Pathstone is equipped with new power management, thermal control, and attitude control subsystems that will be utilized for the CAPSTONE mission to the Moon for NASA later this year. Photon Pathstone is also testing on orbit new deep-space radio capability, an upgraded RCS (reaction control system), and sun sensors and star trackers.

Rocket Lab founder and CEO, Peter Beck, says: �Congratulations and welcome to orbit for all of our customers on Electron. Reaching more than 100 satellites deployed is an incredible achievement for our team and I�m proud of their tireless efforts, which have made Electron the second most frequently launched U.S. rocket annually. Today�s mission was a flawless demonstration of how Electron has changed the way space is accessed. Not only did we deploy six customer satellites, but we also deployed our own pathfinding spacecraft to orbit in preparation for our Moon mission later this year.�

Details about Rocket Lab�s 20^th Electron launch will be announced shortly, with the next mission scheduled to take place from Launch Complex 1 within the next few weeks.
