Two Russian cosmonauts took care of a host of scientific and maintenance choreson the exterior of the International Space Station, including cleaning windows from the outside, during a spacewalk that lasted just a minute over six hours.
They also wished the world’s first spacewalker, Alexei Leonov, a happy birthday. Leonov, a pioneer of the Soviet space program who made history with his 1965 orbital outing and took part in the Apollo-Soyuz Test Project a decade later, turns 85 on May 30.
In his honor, cosmonauts Oleg Kononenko and Alexey Ovchinin wore orange placards praising Leonov on their spacesuits during today’s extravehicular tasks. They also showed off a photo of Leonov that they carried outside with them.
“Mr. Leonov, please accept our heartfelt birthday wishes,” one of the spacewalkers said. “You’re with us here and now in outer space, and for the entire duration of this spacewalk you will be here with us.”
