SpaceX is targeting August 4 for Falcon 9’s launch of Northrop Grumman’s 21st Cygnus mission (NG-21) to the International Space Station from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida. The instantaneous launch window is at 11:02 a.m. EDT, 1502 UTC, 17:02 CEST with a backup launch opportunity available on Sunday, August 4 at 11:02 a.m. ET.
This is the tenth flight of the first stage booster supporting this mission, which previously launched Ax-2, Euclid, Ax-3, CRS-30, SES ASTRA 1P, and four Starlink missions. Following stage separation, Falcon 9 will land on Landing Zone 1 (LZ-1) at Cape Canaveral Space Force Station.
Aboard the Cygnus spacecraft are tests of water recovery technology, a process to produce stem cells in microgravity, studies of the effects of spaceflight on microorganism DNA, liver tissue growth, and live science demonstrations for students.
NG-21 is the twenty-first planned flight of the Cygnus robotic resupply spacecraft and its eighteenth flight to the International Space Station (ISS).
It is planned to launch in August 2024. Northrop Grumman is contracted to NASA under the Commercial Resupply Services II (CRS-2) contract. The capsule is scheduled to be launched aboard a SpaceX Falcon 9 rocket.
Orbital ATK (now Northrop Grumman Innovation Systems) and NASA jointly developed a new space transportation system to provide commercial cargo resupply services to the International Space Station (ISS). Under the Commercial Orbital Transportation Services (COTS) program, Orbital ATK designed, acquired, built, and assembled the Cygnus, an advanced spacecraft using a Pressurized Cargo Module (PCM) provided by industrial partner Thales Alenia Space and a Service Module based on the Orbital GEOStar satellite bus.
NG-21 is the second launch of a Cygnus spacecraft after the exhaustion of the supply of Antares rockets, due to the Russian invasion of Ukraine, losing both the Russian rocket engine supplier and the Ukrainian booster stage supplier.
A Northrop Grumman replacement for Antares will later come about for later missions. The next Cygnus missions will also use Falcon 9, and subsequent mission will use the next-generation Antares 300 series that does not depend on Ukrainian or Russian parts.

NASA didn't leave their comments up... So many interesting questions
