A Dragon spacecraft just gave the International Space Station (ISS) a little boost away from Earth.
SpaceX’s Dragon cargo ship completed a test on Wednesday, September 3, successfully firing its Draco engines for just over five minutes. This maneuver helped elevate the ISS’s orbit to about 260.9 by 256.3 miles (419.9 by 412 km), according to NASA.
The ISS orbits Earth at roughly 250 miles (400 kilometers), but it gradually loses altitude due to atmospheric drag. Even at that height, stray particles can slow it down over time. Cargo missions are needed every few months to lift the station back up.
Historically, Russian Progress spacecraft have taken on this reboosting role. However, Russia plans to withdraw from the ISS program by 2028, just as the station is set to continue functioning until around 2030. NASA has turned to U.S. cargo ships, like SpaceX’s Dragon and Northrop Grumman’s Cygnus, for this critical task. The first of these reboost tests by SpaceX occurred on November 8, 2024.
The recent boost is not just about maintaining altitude; it also sets the stage for future tasks. NASA noted that this new Dragon boost kit will support planned burns which will help manage the ISS’s height through late 2025. These tests are also gearing up for a more significant challenge: safely deorbiting the ISS. NASA tasked SpaceX with this job in July 2024, aiming for a controlled descent using a larger Dragon spacecraft when the time comes.
On August 25, the Dragon spacecraft delivered 5,000 pounds (2,270 kilograms) of supplies and experiments to the ISS. This mission marks SpaceX’s 33rd journey for NASA’s Commercial Resupply Services program, known as CRS-33.
Dragon is expected to remain at the ISS until late December or early January. When it returns to Earth, it will carry experiments and waste back with it, splashing down near California’s coast. This cycle of resupply, reboosting, and eventual deorbiting highlights the ongoing collaboration between SpaceX and NASA, a partnership that is shaping the future of space exploration.
As technology evolves, experts emphasize the importance of sustainable space practices. A study by the United Nations Office for Outer Space Affairs highlights that maintaining satellite orbits is crucial as more countries enter the space race. Keeping the ISS operational and properly managed will be key in setting standards for the future of international space cooperation.
