SpaceX Starship Test Flight

CNBC reported Friday that SpaceX successfully launched its Starship rocket on the second attempt, one day after scrubbing the mission to resolve technical problems. The rocket lifted off at precisely 6:30 p.m. ET from the company’s Starbase facility in South Texas, marking the 12th overall test flight for the vehicle.

Starship Test Flight Deploys Mock Satellites

The flight used the updated Starship V3 configuration and carried simulated Starlink satellites rather than people or paying cargo customers. SpaceX managed to place those dummy payloads into orbit and transmitted live video footage of the vehicle’s systems operating in space. No crew was aboard for this mission.

However, the company fell short on several propulsion benchmarks. Those targets are considered critical before SpaceX can certify Starship as safe to carry human passengers on crewed missions. The shortfall means further development work remains before the rocket is cleared for operational flights with people on board.

Background on Starship’s Development

The Starship system pairs a Super Heavy booster with an upper-stage vehicle, powered by Raptor engines. It is the largest rocket ever constructed or flown. SpaceX designed it to carry up to 100 metric tons to low Earth orbit in a fully reusable format, with rapid turnaround times comparable to commercial aviation.

Friday’s mission was the first Starship flight in seven months. A series of vehicle explosions in early 2025 grounded the program and, in at least one instance, caused debris to scatter across flight paths, forcing airline diversions. The program has had to rebuild credibility since those incidents.

IPO Timing Adds Pressure to Every Launch

The test carries unusual commercial weight. SpaceX publicly filed its IPO prospectus earlier this week and is targeting a public market debut next month. The company is widely expected to seek roughly $75 billion in proceeds, which would rank among the largest offerings in history. SpaceX was last valued at $1.25 trillion in February after merging with Elon Musk‘s AI venture xAI.

NASA Administrator Jared Isaacman traveled to Starbase ahead of liftoff and appeared on the company’s livestream. Isaacman led two private SpaceX missions in 2021 and 2024 before taking the top role at the space agency. NASA is counting on Starship to return astronauts to the lunar surface by 2028. Starship’s higher payload capacity also underpins SpaceX’s ambitions to expand its Starlink internet constellation beyond the 3,000-plus satellites already in orbit.
