The International Space Station is the place to be in April. Multiple arrivals and departures this month make the floating laboratory seem more like a hotel.
Russian space agency Roscosmos cosmonauts Oleg Novitskiy and Pyotr Dubrov and NASA astronaut Mark Vande Hei will launch to the space station from the Baikonur Cosmodrome in Kazakhstan on Friday.
The launch, docking and arrival of the new crew on the space station will air live on NASA’s TV channel and 网站. Launch is expected at 3:42 上午. 和.
Russian cosmonaut Oleg Novitskiy holds up a toy cat that will be used in the Soyuz capsule to help indicate the start of weightlessness. Toys are often used as “zero-G indicators” during launches.
The crew will dock to the station at 7:07 上午. 和, and the hatches between the Soyuz spacecraft and the station will open around 9 上午. 和.
This speedy trip to the space station, which includes two orbits of Earth and about three hours of travel time, is courtesy of the new Soyuz MS-18 spacecraft.
Their arrival will bring the total number of crew members on the station to 10 居民.
Astronauts on the space station have prepared for the new crew by setting up extra sleep stations and freeing up ports.
Russian cosmonauts Sergey Ryzhikov and Sergey Kud-Sverchkov, along with NASA astronaut Kate Rubins, recently relocated the Soyuz MS-17 capsule from its port to make room for the latest crew launching from Baikonur.
Ryzhikov, Kud-Sverchkov and Rubins arrived on the space station in the Soyuz capsule after launching from the Baikonur Cosmodrome in Kazakhstan in October.

The crew members moved their spacecraft from the Rassvet module, which has an Earth-facing port, and relocated it to the Poisk docking port, which faces space, 三月. This freed up the Rassvet module port for the new crew and their Soyuz MS-18 spacecraft.
Rubins, Ryzhikov and Kud-Sverchkov will return to Earth in the Soyuz MS-17 spacecraft on April 17.
Members of the historic NASA-SpaceX Crew-1, including NASA astronauts Victor Glover Jr., Mike Hopkins, Shannon Walker and Japan Aerospace Exploration Agency astronaut Soichi Noguchi, who launched from the US to the space station in November, will also return after the launch of Crew-2 next month.
This second rotation using the NASA-SpaceX Crew Dragon spacecraft will include NASA astronauts Shane Kimbrough and Megan McArthur, Japan Aerospace Exploration Agency astronaut Akihiko Hoshide and European Space Agency astronaut Thomas Pesquet.
Crew-2, which could launch April 22, will join Crew-1 on the space station before Crew-1 returns to Earth.
This is the second spaceflight for Vande Hei, the third spaceflight Novitskiy and the first for Dubrov.
Vande Hei was selected as an astronaut in 2009 and had his first spaceflight experience on the space station from September 2017 to February 2018. 在他的 168 days aboard the station, Vande Hei conducted four spacewalks. This time around, Vande Hei and the crew will work on multiple experiments, including studies about Alzheimer’s disease and portable ultrasound devices.
Vande Hei’s flight on the Soyuz spacecraft is part of a contract with Axiom Space of Houston. In return, NASA will essentially save a seat on a future commercial spacecraft launch in 2023 for a non-NASA space station crew member.
While NASA works with Boeing and SpaceX to ensure safe crew transport to and from the space station using US-based launches, grabbing one seat on the Soyuz means that there will always be at least one US crew member on the space station.
Their launch occurs just three days before the 60th anniversary of cosmonaut Yuri Gagarin’s launch as the first human in space, as well as the 40th anniversary of the first launch of NASA’s space shuttle.
