A few hours ago, Northrop Grumman’s Cygnus XL spacecraft blasted off atop a SpaceX Falcon 9 rocket from Cape Canaveral on its NG-24 or CRS NG-24 mission. After about 15 minutes, it successfully separated from the rocket’s last stage and set on its course. This is the 4th resupply mission to the International Space Station with various payloads launched using the Falcon 9 rocket while waiting for the new version of Northrop Grumman’s Antares rocket to be ready. It’s also the 2nd to see the use of the new version of the Cygnus cargo spacecraft.
The first launch of the new version of the Antares rocket is still scheduled for this year, but in the meantime, Northrop Grumman must complete further resupply missions to the International Space Station with its Cygnus cargo spacecraft. For this reason, this was the fourth launch that used SpaceX’s Falcon 9 rocket, and Northrop Grumman’s next mission may begin in 2027 on the Antares.
This Cygnus spacecraft was named S.S. Steven R. Nagel (1946 – 2014) after the NASA astronaut who participated in four Space Shuttle missions. This cargo spacecraft carries a total of nearly 5,000 kilograms (about 11,000 pounds) of cargo, including various supplies for the crew, hardware, equipment, and various components. The XL version of the Cygnus cargo spacecraft can carry 33% more cargo than the previous version.
A module called the Science Module-3X (SM-3X) for the Cold Atom Lab (CAL) aims to increase the number of atoms for this experiment. These atoms are in clouds cooled to temperatures extremely close to absolute zero, reaching about one-tenth of a billionth of a degree Kelvin. In the microgravity of the International Space Station, this allows for the study of certain quantum effects in ways impossible on Earth.
The Hematopoietic Stem Cell Expansion in Space (InSPA-StemCellEX-H2) experiment will also receive an expansion in the form of new hardware to produce a greater quantity of stem cells for medical research on blood diseases and cancer.
Organisms for the C. elegans Biological Investigation on Microbiome Effect in Space (CBIOMES) experiment will help study the interactions between the microbiome and its hosts. Studies on the link between the health of the gut microbiome and its hosts prove the importance of what is a real ecosystem. This experiment will help develop techniques to improve astronaut well-being during their missions and also address some diseases on Earth.
The Ionospheric Topside Sounding from ISS (Nanoracks-ITSI) will help study space weather by providing useful information on the effects of energetic particles on the ionosphere. The potential effects on radar, communications, and navigation systems make these studies important.
The Cygnus XL spacecraft is scheduled to reach the International Space Station next Monday to be captured by the Canadarm2 robotic arm around 16.40 UTC. If there are no problems, the day after the arrival of the Cygnus, the crew will open the hatch and can start the unloading operations.
