Flight preview

About this launch

Katalyst Space Technologies' robotic space vehicle NEXUS-1 will dock with other satellites to install hardware, reposition spacecraft, and extend mission life, offering a faster, lower-cost alternative to replacement of satellites. NEXUS-1 will begin delivering these services through initial government missions before supporting commercial operators. Initial operations include installing a sensor on a Space Force satellite to detect and identify nearby spacecraft and conducting additional rendezvous and proximity operations to support space domain awareness. Following these missions, NEXUS-1 will transition to commercial servicing operations for communications satellite operators seeking to maintain and upgrade spacecraft already in orbit.
