Following a successful launch of NASA’s Northrop Grumman 21st commercial resupply mission, new scientific experiments and cargo for the agency are bound for the International Space Station.

Northrop Grumman’s Cygnus spacecraft, carrying more than 8,200 pounds of supplies to the orbiting laboratory, lifted off at 11:02 a.m. EDT Sunday on a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida.

Shortly after launch, the spacecraft missed its first ***** due to a late entry to ***** sequencing. Known as the targeted altitude *****, or TB1, it was rescheduled, but aborted shortly after the engine ignited due to a slightly low initial pressure state. There is no indication the engine itself has any problem at this time.

Cygnus is at a safe altitude and

at 2:21 p.m. Northrop Grumman engineers are working a new ***** and trajectory plan and aim to achieve the spacecraft’s original capture time on station.

If all ******** on track, live coverage of the spacecraft’s arrival will begin at 1:30 a.m., Tuesday, Aug. 6, on

NASA astronaut Matthew Dominick will capture Cygnus using the station’s robotic arm at approximately 3:10 a.m., and NASA astronaut Jeanette Epps is backup.

The resupply mission will support dozens of

These are just a sample of the hundreds of investigations conducted aboard the orbiting laboratory in the areas of biology and biotechnology, physical sciences, and Earth and space science. Such research benefits humanity and lays the groundwork for future human exploration through the agency’s Artemis campaign, which will send astronauts to the Moon to prepare for future expeditions to Mars.

The company’s 21st mission to the space station for NASA is the 10th under its Commercial Resupply Services 2 contract.

Cygnus will remain at the orbiting laboratory until January before it departs and disposes of several thousand pounds of trash through its re-entry into Earth’s atmosphere where it will harmlessly ***** up. The spacecraft is named the S.S. Francis R. “*****” Scobee after the former NASA astronaut.
