In a significant achievement for NASA and SpaceX, the Dragon spacecraft has demonstrated its ability to assist in maintaining the International Space Station's (ISS) orbit through a precise burn of its Draco thrusters. This operation took place on November 8 at 12:50 PM EST, lasting 12 minutes and 30 seconds, during which the spacecraft adjusted the ISS's altitude by approximately 0.07 miles at apogee and 0.7 miles at perigee.

This successful reboost marks an important milestone, proving that the SpaceX Dragon can function similarly to the Russian Roscosmos Progress spacecraft and Northrop Grumman's Cygnus, both of which have historically provided this vital service. The ISS requires regular adjustments to its orbit to avoid the gravitational pull back to Earth, and although Europe’s Automated Transfer Vehicle (ATV) once contributed to this effort, it has been retired, leaving a gap that NASA aims to fill.

NASA aims to have multiple options for reboosting the ISS, and the Dragon's successful demonstration opens new possibilities for future missions. Interestingly, funnily enough, this technology could also play a role in the planned controlled deorbiting of the ISS when its service life concludes, with SpaceX recently securing a contract to facilitate this process. Data gathered from the recent reboost burn will be invaluable in designing a new vehicle for the safe return of the ISS to Earth.

The current life expectancy of the ISS is set for 2030; however, recent statements from ESA astronaut Andreas Mogensen suggest that an extension beyond this date is plausible, while Russia has only committed to its participation until 2028.

The Dragon spacecraft, which represents the successful culmination of SpaceX's 31st commercial resupply services mission, launched on November 4 atop a Falcon 9 rocket. During this mission, in addition to demonstrating its reboost capabilities, the freighter delivered over 6,000 pounds of scientific cargo to the ISS, further fueling ongoing research in microgravity.

As the future of the ISS hangs in balance, the ability of the Dragon spacecraft to perform reboosts combined with the strategic planning for its deorbiting paints a picture of an exciting yet uncertain era for human presence in low-Earth orbit. Will other private companies join the race to supply the ISS, or will NASA continue to rely on SpaceX? Stay tuned for more updates as this story develops!
