The ISS is about to receive a new doorway to space

Nanoracks Bishop Airlock Module - Concept of Operations

The International Space Station (ISS) is about to take delivery of what NASA describes as a new “doorway to space.”

The Bishop Airlock Module, that’s its official name, was built by Texas-based Nanoracks and will arrive at the space station early next month as part of SpaceX’s next supply mission. Astronauts currently serving as the station’s Expedition 64 crew will then fit the module to an available port.

Nanoracks’ Bishop Airlock Module is special in that it’ll be the first permanent, commercial addition to the space station. Also, with a height of 1.8 meters and a diameter of 2 meters, it’ll offer fives times the volume that can currently be moved in and out of the orbiting laboratory.

A new doorway to space is coming to the @Space_Station! ????✨

Launching on the 21st commercial resupply mission, @Nanoracks #BishopAirlock Module will allow more researchers and companies to move larger payloads inside and outside the station. Learn more:

Japan provides the only other airlock on the station used for sending equipment into space. The Japanese Experimental Module Airlock was added in 2008, but the larger Nanoracks module paves the way for a greater variety of scientific work involving bigger payloads that can be sent through the doorway into space, while larger payloads will be able to be more easily brought in as well.

“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 quipped in an article about the Bishop Airlock Module.

On a more serious note, the agency says the new module will help to alleviate “a bottleneck slowing down the deployment of new small satellites and CubeSats from the space station. Bishop will also significantly increase the amount of research that can be done in low-Earth orbit — research that helps us better understand the space environment but also has implications for Earth imaging, medical research, and biomanufacturing.”

It added: “Once operational, the new door will mean more access for NASA and everyone else — private companies, academic institutions, public agencies, even citizens.”

While Nanoracks came up with the module’s initial investment and the physical structure, NASA will provide necessities such as power, space-to-ground communications, and astronauts to deal with cargo and carry out experiments.

As we look forward to seeing how the module will be used by private companies and researchers, NASA notes that the space agency itself has already booked multiple slots for use of the airlock for more banal activities, namely the disposal of larger pieces of trash that will later burn up on entry into Earth’s atmosphere.

How NASA’s astronaut class of 1978 changed the face of space exploration
Sally Ride NASA

When you look back on the long history of crewed spaceflight, one group stands out for its radical challenge to the conventional wisdom of who could become an astronaut. NASA's astronaut class of 1978 saw not only its first women and people of color working as astronauts such as Sally Ride and Guy Bluford, but also the first Asian American astronaut, El Onizuka, the first Jewish American astronaut, Judy Resnik, and the first LGBT astronaut, once again Sally Ride.

A new book, The New Guys: The Historic Class of Astronauts That Broke Barriers and Changed the Face of Space Travel, chronicles the story of this class and its impact on both NASA and the wider world’s perceptions of who could be an astronaut. We spoke to the author, Meredith Bagby, about this remarkable group of people and how they changed the face of human spaceflight.
Breaking the mold
Throughout the 50s and 60s, NASA almost exclusively chose fighter pilots for its early human spaceflight program, Project Mercury. That meant that not only were astronaut groups like the famous Mercury Seven entirely composed of white men, but they also came from very similar military backgrounds.

A spacecraft at the ISS is about to take a very short trip
The Soyuz MS-23 spacecraft is seen approaching the Poisk module of the space station prior to docking at 7:58 p.m. EST as the space station was flying 260 miles above northern Mongolia.

Three astronauts at the International Space Station (ISS) are about to take a very short ride aboard a Soyuz spacecraft.

In a maneuver designed to make room for the arrival of the Roscosmos Progress 84 cargo spacecraft later this year, astronaut Frank Rubio of NASA, and Roscosmos cosmonauts Sergey Prokopyev and Dmitri Petelin, will this week hop aboard the Soyuz MS-23 capsule and pilot it from the Poisk module on the space-facing side of the complex to the Prichal module on the Earth-facing side of the outpost.
