1 . Four astronauts headed to the International Space Station (ISS) on Sunday where they will oversee the arrivals of two new rocketships during their half- year stay.

SpaceX’s Falcon rocket was launched from Kennedy Space Center, carrying NASA’s Matthew Dominick, Michael Barratt and Jeanette Epps and Russia’s Alexander Grebenkin. The astronauts should reach the orbiting lab on Tuesday. They will replace a crew from the US, Denmark, Japan and Russia, who have been there since August.

“When are you getting here already?” space station commander Andreas Mogensen asked via Twitter, after three days of delay due to high wind. SpaceX Launch Control termed it “fashionably late”. There was almost another postponement Sunday night. A small leak in the seal of the SpaceX capsule’s hatch caused a last- minute flurry (忙乱) of reviews, but it was thought safe for the whole mission.

The new crew’s six- month stay includes the arrival of two rocketships ordered by NASA．Boeing’s new Starliner capsule with test pilots is due in late April. A month or two later, Sierra Space’s Dream Chaser, a mini shuttle, should arrive. It is for delivering supplies to the station, but not passengers yet.

Epps, who is from New York, is the second Black woman assigned to a long station mission. She said before the flight that she was especially proud to be a role model for girls, especially for Black girls, demonstrating that spaceflight “is an option for them, and that this is not just for other people”.

Also new to space are Dominick, a Navy pilot, and Grebenkin, a former Russian military officer. Barratt, a doctor on his third mission, is the oldest full- time astronaut to fly in space. He turns 65 in April. As for his age, he said before the flight, “As long as we stay healthy and fit and engaged, we’re good to fly.”

An exhibition titled “Learn from the Past and Know the Future: China’s Archaeological (考古学的) Achievements in the New Era” is taking place at the National Museum of China.

It is also worth noting that the design of the exhibition hall was inspired by the unique spatial (空间的) structures of the archaeological sites, offering audiences the chance     10     (understand) the relationship between archaeological work and its outcomes better.
