NASA's Starling mission has overcome early challenges as the spacecraft forms and prepares for advanced constellation technology experiments. The mission team spent the past two months troubleshooting various issues and debugging the four spacecraft, nicknamed "Blinky," "Pinky," "Inky" and "Clyde."
Pinky, Inky and Clyde have successfully completed propulsion system debugging and performed operations to enter swarm operation configuration, maintaining a distance of 50-200 kilometers. The three also successfully demonstrated two-way communications using cross-link radios at such close ranges.
After launch, ground operators discovered a leak in Blinky's propulsion system, causing the spacecraft to enter a slightly lower orbit. The problem was solved, but it left the spacecraft lagging far behind other spacecraft. To correct this problem, the other three spacecraft made some maneuvers to catch up with Blinky. Now that the constellation has been reunited, the Stirling team will continue to test Blinky's propulsion system.
Testing and commissioning the spacecraft is an important step in preparing for swarm experimental operations and understanding the challenges that future spacecraft swarms may encounter. The next mission phase will focus on developing and testing key collaboration technologies.
NASA's Stirling mission represents a major leap forward in space exploration technology, especially in the field of CubeSats. The mission revolves around a group of small spacecraft named Stirling CubeSats, which includes four units with unique nicknames: Blinky, Pinky, Inky and Clyde. The CubeSats are designed to operate in a swarm configuration, a pioneering method of spacecraft formation flying.
The main goal of the Stirling mission is to demonstrate and validate the technologies required for autonomous formation flying of spacecraft. This involves complex maneuvers to maintain a specific formation, in this case keeping the spacecraft within 50-200 kilometers of each other. This formation will be critical for a range of future space exploration missions and experiments, including advanced Earth observation and deep space exploration.
The Stirling program is funded by NASA's Small Spacecraft Technology Program, located at NASA's Ames Research Center in Silicon Valley, California, and NASA's Space Technology Mission Directorate in Washington.
