SpaceX will attempt the first U.S. splashdown of returning astronauts in darkness since the Apollo 8 moonshot in 1968.

NASA and SpaceX are promising more Coast Guard patrols and fewer pleasure boaters for this weekend's splashdown by four astronauts.

An American astronaut and two Russians have returned to Earth after six months aboard the International Space Station.

AdPresident Joe Biden is making good on his promise to end a policy that Trump said was critical to reversing a surge of asylum-seekers, which peaked in 2019. Authorities can process up to 300 a day at the San Diego border crossing, but Hopkins said it's not known when they will change the target of 25 a day. In San Diego, even asylum-seekers who tested negative will quarantine for seven days in hotels under U.S. Centers for Disease Control and Prevention guidelines. A coalition of nongovernmental groups called the San Diego Rapid Response Network will provide hotel rooms, arrange transportation and perform health screenings, Hopkins said. Ad“Who thought this day would come?” Gomez, 36, said Wednesday in Tijuana, Mexico, at a border crossing with San Diego.

The Progress MS-16 cargo ship, which blasted off Monday from the Russia-leased Baikonur launch facility in Kazakhstan, has delivered water, propellant and other supplies to the orbiting outpost. The space station is now operated by NASA’s Kate Rubins, Michael Hopkins, Victor Glover and Shannon Walker; Japan Aerospace Exploration Agency astronaut Soichi Noguchi; and Russian Space Agency Roscosmos’ Sergey Ryzhikov and Sergey Kud-Sverchkov.

(NASA TV via AP)CAPE CANAVERAL, Fla. – SpaceX’s newly launched capsule with four astronauts arrived Monday at the International Space Station, their new home until spring. The Dragon capsule pulled up and docked late Monday night, following a 27-hour, completely automated flight from NASA's Kennedy Space Center. “Oh, what a good voice to hear,” space station astronaut Kate Rubins called out when the Dragon's commander, Mike Hopkins, first made radio contact. And so it will go, with SpaceX — and eventually Boeing — transporting astronauts to and from the station for NASA.

The three Americans and one Japanese should reach the International Space Station late Monday for a five- to six-month stay, following Sunday's liftoff from NASA's Kennedy Space Center. A brief look at each:—Crew commander Mike Hopkins, 51, is an Air Force colonel and former space station resident who grew up on a hog and cattle farm in Missouri. He played football for the University of Illinois and, before becoming an astronaut in 2009, worked at the Pentagon. —Shannon Walker, 55, a Houston-born-and-raised physicist, also has lived before on the space station. She worked as a flight controller at NASA’s Johnson Space Center and then behind the scenes in the space station program, before becoming an astronaut in 2004.

With COVID-19 still surging, NASA continued the safety precautions put in place for SpaceX’s crew launch in May. Even the two astronauts on the first SpaceX crew flight stayed behind at Johnson Space Center in Houston. “I didn’t start breathing until about a minute after it took off,” Pence said during a stop at SpaceX Launch Control to congratulate the workers. Similar pleas for SpaceX’s first crew launch on May 30 went unheeded. The first-stage booster is expected to be recycled by SpaceX for the next crew launch.

Here are answers to five questions about what “basic” life is like for astronauts on the ISS. As if they are going to a restaurant, astronauts can choose which food items they want off of a menu. On the ISS, astronauts use liquid soap, water and no rinse shampoo. Given the microgravity means, there is no up or down, and astronauts can sleep in any orientation, according to NASA. The station has small crew cabins with sleeping bags that astronauts sleep in.
