How NASA is remodeling the International Space Station, 15 years after moving in

Immediately marks the fifteenth anniversary of that first moving-in day for spacefliers residing on the International Space Station – and like many locations which were lived in for 15 years, the ISS is in the midst of renovations.

This isn’t your typical “reno,” nonetheless: There’s no different place the place the doorways have to get replaced whereas the development web site is moving at 18,000 mph, 225 miles above Earth’s floor. That’s principally what’s concerned in getting the station prepared for the arrival of Boeing and SpaceX crew transport ships in the 2017 timeframe.

“To implement it on orbit is extraordinarily complicated, and should be orchestrated very fastidiously,” John Vollmer, Boeing’s chief engineer for the house station challenge, says in a video marking the anniversary. Boeing is the prime contractor for the station’s U.S. phase.

The primary items of the house station were put together in 1998, but it surely took till Nov. 2, 2000, to get the orbital outpost prepared for occupancy. That’s when NASA’s Invoice Shepherd and Russia’s Sergei Krikalev and Yuri Gidzenko moved in to function the first live-aboard crew. The station has been occupied ever since, setting the document for steady orbital habitation. (Shepherd says there are in all probability nonetheless some issues “hidden away in various parts of the original modules” that haven’t been discovered by the crews who adopted.)

Immediately’s station has as a lot residing house as a six-bedroom home (or a Boeing 747), and spreads as large as a soccer area when its photo voltaic arrays are included. Proper now, its occupancy is restricted to 6 spacefliers, as a result of that’s the most seating for the two Soyuz lifeboats which can be connected to the station. However as soon as Boeing’s CST-100 Starliner capsule and SpaceX’s crew-capable Dragon V2 capsule are flying, the crew complement might go up to seven.

When these business crew taxis go into service, it could get America again into the enterprise of launching spacefliers into orbit from U.S. soil for the first time since the retirement of the house shuttle fleet in 2011. However first, the station’s docking ports should be reworked with new tools designed to accommodate the taxis. That’s going to require sending up two International Docking Adapters, often known as IDAs, and having them put in onto the ports throughout a fancy collection of spacewalks.

The primary docking adapter was misplaced in June when a SpaceX resupply mission failed, however NASA is nonetheless aiming to have each entryways put in in time for the taxis’ check flights to the station in 2017. As soon as that’s performed, NASA can scale back its reliance on the Russians, who’re being paid greater than $70 million per seat to move America’s astronauts to and from the station.

The present plan requires the station to stay in operation till 2024, however there’s an opportunity that its lifetime will likely be prolonged even additional. In September, Boeing stated it was awarded a five-year, $1.18 billion NASA contract that features wanting into the risk of retaining the station in service by means of 2028. That may be 30 years after development started – matching the house shuttle program’s 30-year run.
