SpaceX is starting to get the ball rolling on its Florida launch card with its fourth mission of the year coming less than two days since the last launch setting a record for its Cape Canaveral

An astronaut in need of medical care is on the way back to Earth. The ailing astronaut departed the International Space Station with three crewmates on Wednesday.

A member of the Crew-11 SpaceX mission suffered a medical event, prompting an early return to Earth for the four-person crew including NASA members.

SpaceX early Sunday morning launched its first Twilight rideshare flight from California, launching satellites for NASA, an Internet-of-Things services company and an experiment to 3-D print a boom in space.

Instead of remaining at the International Space Station (ISS) for the full duration of their mission, the four crew members are coming home a month early due to a medical issue with one of the astronauts.

A Falcon 9 rocket carrying about 40 payloads, including NASA's Pandora exoplanet satellite, is scheduled to lift off from California's Vandenberg Space Force Base during a 57-minute window that opens at 8:19 a.m. EST (1319 GMT and 5:19 a.m. local California time).
