Private company proposes commercial airlock for ISS
The competion heats up: The private company NanoRacks has proposed building a large airlock for ISS which could be used to launch private cubesates while also allowing NASA to eliminate spacewalks by bringing faulty equipment inside for repairs.
For commercial opportunities, NanoRacks has a small satellite launcher, and it is also designing a “haybale” system to launch as many as 192 cubesats at a time. After the airlock is configured, it would be depressurized and sealed. Then a station robotic arm could grab it, move it away from the vehicle, and deploy its payloads.
NASA is also interested in the opportunity to potentially fix large, external components of the space station. Before the space shuttle’s retirement, NASA used the sizable delivery vehicle to stash dozens of replacement pumps, storage tanks, controller boxes, batteries, and other equipment on the station, known as ORUs. When one of these components broke, astronauts would conduct a spacewalk to install a replacement unit.
However sometimes the problem with a broken unit is relatively minor, such as a problematic circuit card. With a larger airlock, damaged components could be brought inside the station, assessed, and possibly fixed, saving NASA the expense of building and delivering a new unit to the station—or losing a valuable spare. Finally, the space agency could use the airlock to dispose of trash that accumulates on station and can be difficult to get rid of.
It is exactly this kind of technology, spurred by the lure of profits, that interplanetary spaceships need if they are going to be maintainable far from home.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon or from any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

When I first read about NanoRacks, I thought they had a good idea. I didn’t realize that they would be one of the most important lessons to commercializing space.
NASA can be a horrible bureaucracy to deal with when doing something with them. NanoRacks’ initial mission was to be the go-between for small experimenters, such as universities, and NASA’s ISS program. They provided a service that made sure the bureaucrats were satisfied and that the scientists were not turned off or turned away by the bureaucracy.
It is clear that they are very successful. From the article: “We started thinking about it and realized we have enough business now where we could actually self-fund an airlock.”
Over time, they learned other important lessons, such as the proper training of astronauts in the operation of the experiments. Now they seem to have improved ideas for other operations.
This is part of the learning experience that we are gaining from the ISS. Expensive though ISS is, what is learned here can be incorporated into Bigelow’s space habitats and any other proposed space stations.
Combine this with Made In Space’s zero-G 3D printing technology then we get, as Robert noted, ease of maintainability for future spacecraft, especially those travelling far from home and spare parts.
