Antares lifted off Tuesday from Pad-0A at NASA’s Wallops Flight Facility in Virginia, carrying the space agency’s Cygnus cargo spacecraft to bring hardware, science experiments and crew supplies to ISS.
Dubbed the S.S. Laurel Clark, Cygnus carries over 20 experiments sponsored by the ISS National Laboratory, including technology demonstrations to evaluate Earth-monitoring sensors, material science investigations and space antenna upgrades.
The spacecraft will also transport to ISS biological research experiments focused on human health.
Cygnus is scheduled to arrive at the orbiting station on Aug. 4.
The launch mission marks the final flight of the Antares 230 series developed with Russian and Ukrainian components.
In August 2022, Northrop teamed up with Firefly Aerospace to build a new first stage for an upgraded Antares 330 series rocket scheduled for launch in the second half of 2024.
