Russian spacewalk will prepare space station for new module

That's right; both bear the first name Sergey, spelled exactly the same way.

Mr Ryzhikov and Mr Kud-Sverchkov have been at the ISS for the past 35 days, after launching from the Baikonur Cosmodrome in Kazakhstan, along with Nasa astronaut Kate Rubins.

During the spacewalk, the cosmonauts are expected to carry out maintenance tasks on Russia's Poisk, Zvezda, and Zarya modules and dismantle parts of a Soyuz spacecraft outside the ISS.

Are you anxious about the two astronauts telling each other?

Russian space agency Roscosmos Sergei Ryzhikov and Sergei Kud-Sverchkov make space walk installations that prepare the station for the new module.

Ryzhikov will be designated EV1 and Kud-Sverchkov will be designated EV2 - which is less confusing than when they were referred to as "Sergey 1" and "Sergey 2" during a press conference appearance aboard the space station in October. You can watch it live here, on, courtesy of NASA TV, or directly via the agency's website.

Two Russian cosmonauts wearing bulky spacesuits used the International Space Station's poisk docking compartment for the first time on Wednesday as an airlock on a spacewalk to prepare the almost identical Pirs module for removal next year.

Because this will be the first time that anyone has used the Poisk module as an airlock for a spacewalking excursion, the cosmonauts will first spend some time checking out the hatch and inspecting it for leaks.

The new Russian multipurpose laboratory module, called "Nauka" in Russian for "science", will be replaced by the Russian Birs module. Birs will be fired, unopened and removed in the future.

Nauka will be launched next year from Kazakhstan. The Russians are preparing to remove and discard the almost identical Pirs module on the opposite side of the station to make room for a new laboratory.

"We welcome any and all units, especially if they have storage space", Robins said in October.

NASA SpaceX Crew-1 took off from the space station on Tuesday, bringing the total number of astronauts on the station to seven (except one).

Zero Gravity Indicators, usually cute toys, let the crew know when they reach space after launch. Once the game starts to float, they know they're in space. Each crew must choose their own indicator, according to NASA.

Crew-1 took NASA astronauts Victor Clover Jr., Michael Hopkins and Shannon Walker and Sochi Nokuchi of Japan to the space station for a six-month stay.

NASA's Commercial Crew program could expand the number of astronauts on the space station - which means more science, and even new types of experiments, can happen in the unique microgravity environment.

All seven groups held a reception on Tuesday.

It is a historic moment for the space station. It will be the first long-term pilot of the space station with seven members in 20 years. November 2 marks 20 years of continuous human presence on the space station.

Earlier, the space station catered to 13 people, but only a few days later the crew arrived.
