SpaceX Dragon Completes Successful Reboost Test for ISS, Advancing NASA’s Long-Term Plans
SpaceX’s Dragon spacecraft has successfully conducted a reboost test for the International Space Station (ISS), marking a significant advancement in its operational capabilities. The test adjusted the ISS’s orbit, demonstrating that Dragon can now help maintain station stability, a role previously handled only by Northrop Grumman’s Cygnus and Russia’s Progress spacecraft. This test is part of NASA’s strategy to enhance ISS flexibility as it approaches its planned deorbiting in 2031. NASA has awarded SpaceX an $843 million contract to develop a deorbit vehicle for the ISS, with data from this test informing that vehicle’s design. The achievement highlights SpaceX’s expanding role in NASA’s objectives, including future deep-space missions.
SpaceX Dragon Completes Successful Reboost Test for International Space Station
The SpaceX Dragon spacecraft has successfully conducted a reboost test for the International Space Station (ISS), showcasing an important enhancement in its operational capabilities. During the test, Dragon’s Draco thrusters fired for approximately 12.5 minutes, adjusting the ISS’s orbit by raising the apogee by 0.07 miles and the perigee by 0.7 miles.
This reboost demonstration is part of NASA’s broader efforts to increase ISS operational flexibility as it approaches its planned deorbiting in 2031. Previously, only Northrop Grumman’s Cygnus and Russia’s Progress spacecraft have performed these reboosts, making this a significant upgrade for Dragon. Bill Spetch, NASA’s ISS operations manager, highlighted the test’s importance, noting that it expands the range of vehicles able to maintain the ISS’s stability.
NASA has tasked SpaceX with a critical role in the ISS’s end-of-life planning, awarding the company an $843 million contract to develop a specialized deorbit vehicle that will safely guide the ISS back to Earth, reducing risks to populated areas during re-entry. Data from this reboost test will be vital for designing the deorbit vehicle and for understanding the performance of Dragon’s Draco thrusters under these conditions.
This successful reboost also underscores SpaceX’s expanding role in NASA’s future plans. With the Artemis program targeting lunar and Mars missions, SpaceX’s support for ISS operations is a promising step toward broader ambitions in deep-space exploration.
