A SpaceX Dragon cargo ship will depart space station today with a 'cytoskeleton' on board. Here's how to watch.

The NASA TV broadcast will begin coverage at 10:15 a.m. The time is 1515 GMT.

You can watch the live stream on Saturday as the Dragon ship gets ready to send the science back to Earth.

The coverage will start at 10:15 a.m. NASA TV, the agency's website, agency social media and here at Space.com are all on the same day. The Dragon cargo ship will leave the dock at 10:40 a.m. Return to Earth on Monday.

There will be a "cytoskeleton" that uses cell signaling to understand how the human body changes in microgravity and a 12-year-old light microscope that is retiring from studying the structure of matter and plants in space.

There are some good videos for you. It was created with a sketch.

There will be no live coverage of the splashdown, but the current target calls for Dragon to arrive somewhere off the coast of Florida around 12:44 a.m. On Monday, the time is 0552GMT. There will be updates on the space station.

The International Space Station's space-facing docking port will be unlatched from the Dragon cargo ship on January 22, 2021. The image is from NASA.

Poor weather conditions caused the procedure to be delayed from Friday to Saturday.

On December 21st, the Dragon spaceship blasted off on its cargo mission, and two days later it delivered both science and Christmas gifts to the space station.

Dragon is the only cargo ship that can fly scientific experiments back to researchers on Earth, as all other cargo ships burn up in the atmosphere. Dragon is often used to carry back biological samples that need to be transferred to a scientific facility quickly, and splashing down in the Atlantic Ocean will allow for rapid transfer of samples to NASA's Kennedy Space Center in coastal Florida.

The crew of the space station has been packing up and organizing Dragon supplies for at least the last two weeks.
