SpaceX is preparing for the 12th test flight of its Starship rocket, scheduled for Thursday with a launch window opening at 3:30 p.m. PT and lasting 90 minutes. This is the official debut of the Starship V3, which the company has been actively testing since November 2025. The rocket will launch from the Starbase test site in South Texas, ascend into low orbit, coast and then splash down. The entire test is expected to take about one hour. The booster will fall into the Gulf of Mexico, and the upper stage into the Indian Ocean. This test flight also features a satellite launch: two modified Starlink satellites will analyze the spacecraft‘s heat shields. Several tiles have been painted white to simulate missing tiles, and one panel has been removed to measure aerodynamic differences. This article covers the launch details, satellite mission, IPO plans and what is at stake for SpaceX.
Starship V3 Test Flight Details
| Aspect | Detail |
|---|---|
| Launch Date | Thursday (May 21, 2026) |
| Launch Window | Opens at 3:30 p.m. PT, lasts 90 minutes |
| Launch Site | Starbase, South Texas |
| Flight Profile | Ascend to low orbit, coast, splash down (approx 1 hour) |
| Booster Splashdown | Gulf of Mexico |
| Upper Stage Splashdown | Indian Ocean |
| Payload | Two modified Starlink satellites |
| Primary Mission | Analyze heat shield tiles, aerodynamic differences |
SpaceX intends to eventually land the Starship for reuse, but for this test, everything will end up in the water.
Starlink Satellite Mission
The Starship V3 is carrying two modified Starlink satellites. Their mission is to analyze the spacecraft‘s heat shields to ensure they are functioning correctly.
- Several of the Starship‘s tiles have been painted white to simulate missing tiles. These will act as targets for satellite imagery.
- One panel has been removed to measure the aerodynamic differences between adjacent tiles during spaceflight.
This is the first time Starship has carried a payload other than itself.
SpaceX IPO Plans
The biggest underlying story is SpaceX‘s plans to go public. In a filing dating back to April, SpaceX says it wants to raise 75 billion USD. This would surpass Saudi Aramco‘s previous record of 29.4 billion USD (2019) and become the largest IPO in stock market history.
| IPO Detail | Information |
|---|---|
| Amount to Raise | 75 billion USD |
| Record Beaten | Saudi Aramco (29.4 billion USD in 2019) |
| Use of Funds | AI, space exploration, satellite ventures |
| Potential Valuation | Approximately 1.75 trillion USD |
| IPO Timing | June 2026 |
SpaceX plans to use the money raised to fund AI, space exploration and satellite ventures.

Why This Test Flight Matters
SpaceX test launches are fairly common. The company has done thousands of engine hotfires and hundreds of full scale flight tests. It launched over 160 missions to orbit in 2025, setting a company record for most production flights in a single year.
However, the Starship V3 test flight has extra weight behind it for several reasons:
- It is the rocket expected to carry the Artemis IV crew to the moon‘s surface and back to Earth in 2028.
- It is the rocket that SpaceX plans to use to deploy Starlink‘s V3 satellites into orbit in the second half of 2026.
- Wall Street investors see this test as a make or break scenario ahead of the IPO.
- If the Starship V3 fails, it could shake shareholders.
- If everything goes off without a hitch, including the IPO next month, SpaceX could become one of the most valuable companies of all time, with a possible valuation around 1.75 trillion USD.
