Elon Musk's SpaceX is gearing up for its biggest launch yet, with the maiden flight of its Starship rocket. You can watch the launch streamed live above. SpaceX is set to send its Starship rocket into near orbit for the first time at 1300 GMT today – that's 1400 BST in the UK and 0800 CDT in Boca Chica, Texas, where it will lift off. The largest and most powerful rocket system ever built. SpaceX says it will eventually ferry astronauts to the moon and Mars, if all goes according to plan.

This afternoon, SpaceX is slated to launch its latest cargo mission from Florida for NASA, sending about 5,000 pounds of supplies to the crew on the International Space Station. For this mission, the company is employing a Dragon cargo capsule that's already been to space twice before. If successful, it'll be the first time the same Dragon has gone on a third trip to space. Packed inside the Dragon's main storage compartment are some interesting goodies and science experiments for the crew to work with over the next few months. These include a printer designed to create 3D organ-like tissues in space, as well as an experiment to culture cells taken from patients with multiple sclerosis and Parkinson's disease. The launch will also be carrying a key piece of hardware for the station itself.
