SpaceX readies its seventh test flight of Starship, the most powerful rocket ever designed. The trial will test upgrades to the spacecraft and deploy mock satellites.

SpaceX will launch Starship for a seventh test flight on Wednesday, an experiment that will feature the spacecraft’s first payload deployment test, marking what could be the latest milestone for the Elon Musk-owned aerospace company as it develops reusable rockets.

Tonight, the rocket which is designed to be able to reach Mars will launch again, with a window starting at 10pm GMT. This will be its seventh test flight, and will be livestreamed from south Texas. At 122m tall, Starship is designed to help humans go interplanetary, colonising Mars. Nasa also intends to use it to take astronauts back to the Moon.
