SpaceX’s latest Dragon mission will breathe more fire at the space station

SMRTR summary

SpaceX's Dragon mission will add a reboost kit to the International Space Station, featuring engines for optimal propellant efficiency. The system can increase the station's speed by about 20 mph, providing roughly one-third of the ISS's annual orbit maintenance needs. Periodic burns will begin in September through fall 2025 to maintain the station's altitude. This is SpaceX's 50th Dragon mission to the ISS, having delivered over 300,000 pounds of cargo and supported more than 1,000 research projects. The reboost kit design will also inform development of the $843 million US Deorbit Vehicle for the ISS's atmospheric reentry in the 2030s.
