Virgin Orbit and Poland-based satellite manufacturer SatRev have announced a follow-on launch services agreement for the latter’s satellites.

The deal gives SatRev “the flexibility to launch 500 kg over multiple launches to a variety of different orbital planes from the Mojave Air and Space Port in California, USA and/or from other international launch sites as they come online with mission requirements”, according to the joint statement by the companies.

The announcement came after four satellites built by SatRev were delivered to low earth orbit by Virgin Orbit’s LauncherOne system onboard missions Tubular Bells and Above the Clouds.

The team at SatRev continues to advance the frontiers of what is possible to accomplish with a constellation of smaller, more affordable satellites. SatRev has been a great collaborator, and we are excited by what the future holds as they expand their constellation and continue to bring top-notch space services to their international customer base,” said Dan Hart, chief executive of Virgin Orbit.

“Today marks a major milestone for SatRev as we officially announce our Launch Service Agreement with Virgin Orbit. This three-year partnership further solidifies our commitment to providing reliable and cost-effective access to space for our customers,” said SatRev chief executive Grzegorz Zwoliński.
