Watch the ISS attach its new doorway to space

NEW AIRLOCK ATTACHED TO THE SPACE STATION

The International Space Station (ISS) now has a new doorway to space.

A video (top) posted by NASA on Monday shows the station’s robotic arm — operated by folks at Mission Control in Houston — detaching the Bishop Airlock from the trunk of SpaceX’s recently docked Cargo Dragon capsule and then connecting it to the station’s Tranquility module.

Built by Texas-based Nanoracks, the new bell-jar-shaped airlock is the first permanent, commercial addition to the space station in the orbiting outpost’s 20-year history.

NASA said the new airlock will be used by commercial customers for payload deployments, as well as for moving equipment from one location to another outside the station. It will also be used to jettison trash that accumulates aboard earthlings’ home away from home

The Bishop Airlock is 8 feet in diameter and 7 feet high, weighs more than a ton, and will be robotically detached from Tranquility and reattached each time it’s needed.

Up until now, the station’s only module for sending items into space has been Japan’s Experimental Module Airlock, which was added to the ISS 12 years ago.

With a size five times that of the Japanese airlock, Nanoracks’ module offers new opportunities to carry out a wider range of scientific work using more sizable payloads that can be sent through the doorway into space, while larger payloads can now be brought in more easily, too.

“Anyone who has gotten a sofa stuck in a doorway on moving day knows how frustrating it is when there’s no other way in or out,” NASA joked in a recent article as a way of explaining some of the advantages of the new module.

Importantly, the agency says the Bishop Airlock will help to speed up the deployment of small satellites and CubeSats from the space station. It will also help to increase the number of research projects undertaken in low-Earth orbit aimed at giving scientists a greater understanding of the space environment, while also helping to advance developments in Earth imaging, medical research, and biomanufacturing.

The Bishop Airlock also gives private companies, academic institutions, public agencies, and even citizens, the chance to carry out their own experiments and research in space.

That 8-day Starliner space mission is now 233 days in
Butch Wilmore and Suni Williams.

Just before NASA astronauts Butch Wilmore and Suni Williams headed to the Starliner spacecraft on the launchpad at Cape Canaveral in Florida in June last year, they will have probably said something to their family and friends along the lines of: “See you next week.”

That's because their stay aboard the International Space Station (ISS) was scheduled to last eight days in what was the first crewed flight of the Starliner. But the mission took an unexpected turn when the spacecraft developed several technical issues on the way to the ISS. Fortunately, the capsule managed to dock, and Wilmore and Williams were able to safely board the ISS. However, after weeks of trying to resolve the issues, it was eventually decided that, out of an abundance of caution, the Starliner would be brought home empty.

Astronaut’s ‘glowing fingernail clipping’ is actually the moon
A waning crescent moon as seen from the space station.

Don Pettit is on a roll. Just days after sharing a breathtaking shot of Earth, the American astronaut has followed up with an equally stunning shot of a waning crescent moon, or, as Pettit put it: “a glowing fingernail clipping in the sky.”

With 16 sunrises a day, when does it become 2025 on the space station?
The International Space Station.

Life on the International Space Station (ISS) is anything but ordinary. The microgravity conditions mean you spend most of your time floating around the place, and the views from the windows are special, to say the least. Popping outside requires donning protective clothing, and going to the bathroom is a more complicated process than back on terra firma.

And due to the ISS orbiting Earth at around 17,000 mph, astronauts stationed there witness 16 sunrises and 16 sunsets in every 24-hour period. So how will the current crew -- NASA astronauts Suni Williams, Butch Wilmore, Don Pettit, and Nick Hague, together with Russian cosmonauts Aleksandr Gorbunov, Alexey Ovchinin, and Ivan Vagner -- know when to celebrate the arrival of 2025?
