In short: The Orbital-2 mission is preparing to deliver over 3,000 pounds of essential cargo to the International Space Station. Beyond simple provisions, this resupply flight carries complex experiments designed to expand the research capabilities of the Expedition 40 crew members currently living in microgravity.

The Orbital-2 mission utilizes Orbital Sciences Corporation’s Cygnus cargo spacecraft to ferry critical supplies to the International Space Station. Scheduled to launch from Launch Pad 0A at the Mid-Atlantic Regional Spaceport within NASA’s Wallops Flight Facility in Virginia, the mission serves as a vital component of commercial cargo resupply efforts. These flights are designed to bolster national capability for delivering science research to orbit, enhancing NASA's ability to conduct investigations in the only microgravity laboratory available. The launch is slated for Friday, July 11, at 1:40 p.m. EDT. This mission represents a key part of a broader strategy to ensure a steady flow of materials to orbit.

The cargo manifest includes a diverse array of hardware, ranging from crew provisions and spare parts to sophisticated scientific equipment. Notable payloads include a flock of Earth-imaging nanosatellites developed by Planet Labs of San Francisco, and TechEdSat-4, a project from NASA’s Ames Research Center in California. TechEdSat-4 is specifically designed to develop technology that may eventually allow small samples to be returned from the station to Earth. The payload also contains various student experiments. These are being flown in partnership with the National Center for Earth and Space Science Education.

Once the Cygnus reaches the station, NASA and European Space Agency crew members—Commander Steven Swanson and Flight Engineer Alexander Gerst—will use the station's robotic arm to capture the craft. The installation process will conclude with the spacecraft being attached to the Earth-facing port of the Harmony module. The capture and docking procedure is expected to take place on Tuesday, July 15. During this phase, the crew will monitor the process from the station's cupola.
