The company will continue supporting the International Space Station through 2030 but plans to retire Dragon afterward. SpaceX has also told private space station developers including Axiom Space, Voyager Space and Vast Space that it will not provide Crew Dragon missions. The shift follows SpaceX earning most revenue from Starlink, with future plans centered on Starlink and orbital data centers. NASA spent $3.1 billion through its commercial crew program, yet SpaceX has already flown 13 crewed missions beyond the original six-mission contract. SpaceX told NASA it has no current interest in developing Starship for crewed low Earth orbit launches. Crewed ascent and re-entry raise additional safety and regulatory issues that Starship has not yet addressed. NASA would have limited ability to require continued Dragon flights beyond the existing contract commitments. Source: digitaltoday.co.kr
Community BuzzThe CounterpointOne thing worth watching is that SpaceX has told NASA it has no current interest in developing Starship for crewed low Earth orbit launches. Source: digitaltoday.co.kr AI & ComputeEngineering Deep DiveThe engineering angle on Hanwha Aerospace's demonstrator centers on proving throttleable staged combustion cycle operation in a vertical takeoff and landing profile. The single engine must vary thrust across the full flight envelope while the vehicle maintains attitude control through a 90-second ascent to 500 meters. That requirement forces the turbopump and injector design to handle rapid mixture ratio changes without combustion instability, a constraint that grows harder at larger scales. The 12.2 meter height and 1.5 meter diameter keep structural mass low enough that the engine can land the stack on a single throttle setting rather than requiring multiple engines or grid fins. Once the 2028 test confirms guidance loop closure and engine restart reliability, the data directly informs first-stage reuse on Korea's mid-2030s vehicle, where recovering only the booster can cut per-kilogram launch cost by roughly half compared with expendable designs. The same throttle authority also reduces the Idiot Index on the engine itself: raw turbopump and chamber materials represent a small fraction of finished engine cost, yet the control software and test campaign multiply that number several times until reuse amortizes the investment across dozens of flights. Staged combustion cycle engines achieve higher specific impulse than gas-generator cycles by routing all propellant through the turbine before injection, yet they demand precise valve timing to avoid hard starts or chugging during throttle transients. The 500-meter target altitude keeps the vehicle inside visual range for telemetry validation while exposing it to enough dynamic pressure to test attitude authority without requiring full orbital energy. Vertical landing at that scale validates the same guidance algorithms later needed for booster recovery, where the vehicle must null both horizontal and vertical velocity within a few meters of the target pad. The 2028 flight therefore serves as a low-cost risk-reduction step before committing to the larger first stage planned for the mid-2030s vehicle, where the economic payoff of reuse becomes material only after the engine demonstrates repeated ignition and throttling without refurbishment. Market WatchSPCX is at $149.24, -0.2% versus the previous close. One-sentence sign-off |
