Northrop Grumman’s Cygnus Spacecraft Successfully Resupplies ISS After Overcoming Software Glitch
After a day of delays due to an unexpected software issue, Northrop Grumman’s Cygnus XL cargo freighter finally reached the International Space Station on Thursday, bringing with it over 5 tons of essential supplies and experiments for the station’s crew.
The resupply mission, which began with an on-time launch from Cape Canaveral, Florida, aboard a SpaceX Falcon 9 rocket on Sunday, encountered trouble early Tuesday when the ship’s main engine shut down earlier than planned during two burns to fine-tune its approach to the space station. The premature engine shutdowns were caused by onboard software designed to protect the spacecraft from a potential problem.
Data transmitted from the spacecraft back to Northrop Grumman’s mission control center in Northern Virginia confirmed that the engine itself operated normally, but the software glitch had triggered an early shutdown of the main engine. The issue prevented the spacecraft from reaching the ISS as scheduled, forcing NASA to announce on Wednesday that the mission would be delayed.
However, after analyzing the data and updating the software parameters, Northrop Grumman’s engineers were able to adapt and continue with the mission. On Thursday morning, the Cygnus spacecraft flew itself to within 30 feet of the space station, close enough for NASA astronaut Jonny Kim to use the robotic arm to reach out and grapple it.
The successful docking of the Cygnus XL spacecraft was a major milestone for the Northrop Grumman team, who were eager to see their upgraded spacecraft in action. The new Cygnus XL is 5.2 feet longer than its predecessor, with a capacity to carry 33 percent more cargo. This mission is the first flight of the upgraded spacecraft, and it brought a total of 10,827 pounds (4,911 kilograms) of supplies and experiments to the ISS.
Among the critical cargo items delivered by the Cygnus XL are food, oxygen, and nitrogen for the station’s crew, as well as spare parts for the urine processor. The urine processor is an essential component of the space station’s life support system, helping to convert waste into fresh drinking water for the astronauts.
In addition to these vital supplies, the Cygnus XL also carried a new navigation aid designed to be mounted outside the space station. This innovative technology will help future crew and cargo ships guide themselves toward the ISS with greater accuracy and precision.
The resupply mission was also notable for its research payload, which includes cutting-edge experiments aimed at advancing our understanding of microgravity and long-duration spaceflight. Among these experiments is a study on the production of semiconductor crystals in microgravity, which could have significant implications for future technological advancements on Earth and beyond.
