Starship — the spacecraft that Elon Musk says will one day take people to Mars — is preparing for its eighth test flight.

This trip to space, on Monday, will largely be a do-over of the seventh flight, which launched in January. In that test, Starship’s mammoth booster, or the bottom of the rocket, successfully returned to the launchpad, but the upper-stage spacecraft disintegrated over the Caribbean, with some debris landing on the Turks and Caicos Islands.

The latest flight aims to come to a less explosive conclusion. Here’s what you need to know about Monday’s flight.

When is the launch and how can I watch it?

The launch is scheduled to occur during a one-hour window beginning at 6:30 p.m. Eastern time from Starbase, SpaceX’s launch site in South Texas. SpaceX will provide coverage on its website beginning about 40 minutes before liftoff.

Whether the weather is favorable might be more uncertain because of gusty winds. The last Starship launch took place during similar conditions.

What is Starship?

The Starship rocket system is the largest ever built. At 403 feet tall, it’s nearly 100 feet taller than the Statue of Liberty atop its pedestal.
