Apollo 8 astronaut Bill Anders, who snapped one of the most famous photographs taken in outer space, has died in a plane crash at the age of 90. Officials say a small aircraft he was flying crashed into the sea off Washington state. Anders' son Greg confirmed that his father's body was recovered on Friday afternoon. "The family is devastated. He was a great pilot. He will be missed," a statement from the family reads. Anders - who was a lunar module pilot on the Apollo 8 mission - took the iconic Earthrise photograph, one of the most memorable and inspirational images of Earth from space.

Astronauts Tracy C. Dyson and Matt Dominick will exit the ISS' Quest airlock to perform a number of tasks in the 90th spacewalk for the U.S., including removing a faulty electronics box from a communications antenna on the starboard side of the station. According to NASA, the astronauts will also collect samples for "analysis to understand the ability of microorganisms to survive and reproduce on the exterior of the orbiting laboratory."

USA TODAY is providing live coverage of the spacewalk, which is scheduled to begin around 8 a.m. ET and will last for about 6 hours from the International Space Station, orbiting above Earth.

But as of Tuesday, mission officials were targeting June 18 for Starliner's undocking from the station. Roughly six hours later the spacecraft would land in the desert of White Sands Missile Range in New Mexico, Willcox Playa in Arizona or other similar predetermined locations, pending weather conditions. Dina Contella, NASA's deputy program manager for the ISS, told reporters on Tuesday that NASA had detected a new issue on Starliner while it remained docked to the station - a "sticky" oxidizer valve.
