SpaceX Targets Starship's First Orbital Flight Today: The Crucial Test the Rocket Has Yet to Pass

SpaceX is targeting Monday, 28 September, for Starship's first flight into Earth orbit, a milestone that would move the rocket beyond its earlier suborbital tests and towards deploying working satellite payloads.

SpaceX is targeting liftoff from Starbase in Texas during a 75-minute window opening at 7:15am CDT (1:15pm BST) on 28 September. The 75-minute window runs until 2:30pm BST, although the published schedule remains a target rather than a guarantee of liftoff.

Reaching Space Is Not the Same as Reaching Orbit

The distinction behind the headline is speed and trajectory. A spacecraft can reach space without travelling fast enough to remain in orbit. On a suborbital flight, its path brings it back into the atmosphere instead of allowing it to keep circling Earth.

NASA explains that an orbiting object is continually falling towards the planet while moving sideways fast enough to keep missing the surface. Gravity still acts on it; being in orbit does not mean escaping Earth's gravitational pull.

For Starship, the next step is more than another high-altitude flight. Entering orbit would establish a capability needed for missions that must remain above Earth rather than return on their initial trajectory.

What the Previous Flight Already Proved

SpaceX's account of Flight 13, which launched on 24 July, describes an upper stage that completed its planned ascent, deployed Starlink satellites and demonstrated an engine restart in space.

Those satellites followed a trajectory intended to bring them back into the atmosphere. SpaceX said they were expected to burn up approximately 20 minutes after deployment. Their release was a development test, rather than the start of an operational satellite mission.

The company also reported that the upper stage survived re-entry and completed a soft splashdown in the Indian Ocean, providing views of its intact heat shield.

That history matters when assessing Flight 14. Starship has already demonstrated several individual flight capabilities; sustained orbital operations represent a further step.

The Return Burn Is a Critical Check

SpaceX says Flight 14 will carry 26 Starlink V3 satellites for orbital deployment. However, entering orbit is conditional on checks confirming sufficient backup capability in hardware needed for the subsequent deorbit burn.

That burn changes the spacecraft's trajectory to begin its return. The safety check links the decision to stay in space with the ability to leave orbit deliberately.

It also makes liftoff only the opening milestone. An orbital insertion, successful payload release and controlled return are separate outcomes, each requiring confirmation during the mission.

Why NASA Has a Stake in Starship's Progress

Starship's development also feeds into NASA's Artemis programme. The agency is working with SpaceX on a lunar lander derived from the vehicle, with orbital testing forming part of preparations for future Moon missions.

NASA's July mission outline describes an Artemis III demonstration in 2027 involving rendezvous and docking between Orion and commercial lander test vehicles. Its Starship test article would use Version 3 hardware with an added docking system.

Astronauts would not enter the Starship test vehicle during that mission. Flight 14 is a separate launch, but developing reliable orbital operations is a necessary foundation for such later tests.

For Monday's attempt, the immediate question is whether Starship can turn that first orbital objective into a demonstrated capability.
