'Alien' encounter: ISS crew member plays joke as SpaceX team arrives

Even astronauts have a sense of humor, as shown during NASA's Crew-10 docking on the International Space Station (ISS), when they were met by an "alien" early Sunday morning.

Russian cosmonaut Ivan Vagner wore an alien mask while welcoming four newcomers after their SpaceX Crew Dragon capsule docked to the station at 12:04 a.m., about 29 hours after launching at 7:03 p.m. on Friday from NASA's Kennedy Space Center in Florida.

While ISS crew members were preparing the capsule for deboarding, Vagner could be seen floating around while wearing a mask, a hoodie, pants and socks during the "lighthearted moment," a NASA spokesperson said in a statement to Fox News Digital. 

"NASA astronauts Anne McClain and Nichole Ayers, JAXA (Japan Aerospace Exploration Agency) astronaut Takuya Onishi, and Roscosmos cosmonaut Kirill Peskov entered the International Space Station shortly after opening the hatches between the space station and the SpaceX Dragon spacecraft at 1:35 a.m. EDT," NASA said in a statement.

Following the hatch opening by Suni Williams, the ship's bell was rung as the new arrivals floated in, shook hands and hugged the Expedition 72 crew after Vagner's practical joke. 

"It was a wonderful day. Great to see our friends arrive," Williams told Mission Control.

Williams and Butch Wilmore are expected to show the new arrivals the ins and outs of the space station before they finally return home after nine months. Their mission was only scheduled to last one week after the launch of Boeing's first astronaut flight, but they were stuck in space after issues forced NASA to bring the Boeing Starliner back empty.

Crew-9 commander Nick Hague and Russian cosmonaut Aleksandr Gorbunov are scheduled to depart the station on Wednesday as early as 4 a.m. before splashing down off Florida's coast.
