Teenaged Space Station Thriving After 15 Years Of Science, Extreme Construction And Tricky Repairs

Extreme conditions surround the International Space Station’s scientific work, to say the least. It takes a rocketship to get there. Construction required more than 1,000 hours of people using spacesuits. Astronauts must balance their scientific work with the need to repair stuff when it breaks (like an ammonia coolant leak this past spring.)

But amid these conditions, despite what could have been show-stoppers to construction such as the Columbia shuttle tragedy of 2003, and in the face of changing political priorities and funding from the many nations building the station, there the ISS orbits. Fully built, although more is being added every year. The first module (Zarya) launched into space 15 years ago tomorrow. Humans have been on board continuously since November 2000, an incredible 13 years.

The bulk of construction wrapped up in 2011, but the station is still growing and changing and producing science for the researchers sending experiments up there. Below are some of the milestones of construction in the past couple of decades. Did we miss something important? Let us know in the comments.

From time to time, astronauts are called upon to perform tricky repairs to the International Space Station. This October 2007 spacewalk by NASA astronaut Scott Parazynski during shuttle mission STS-120 repaired tears to one of the station’s solar panels — while the panel was powered. Spacewalks have also addressed ammonia leaks, among other things. Credit: NASA
European Space Agency astronaut Hans Schlegel works on installing the ESA Columbus laboratory in 2008. The ten racks on board Columbus can be worked on by astronauts or controlled remotely from a center in Germany. NASA is trying to position the station as an orbiting laboratory that can perform experiments that are impossible on Earth, but astronauts must balance science work with maintenance tasks aboard the station.

Space station construction is still ongoing. In 2015, the Bigelow Expandable Activity Module (BEAM) will be attached to the station as a sort of inflatable room. The test will examine the viability of inflatable structures in space. Pictured in front are NASA Deputy Administrator Lori Garver and Robert T. Bigelow, president and founder of Bigelow Aerospace in 2013. NASA/Bill Ingalls

    1. I guess they would rather choose to give up the initiative to the Russians, Indians, and the Chinese. They are to busy pouring money down the drain on the military, and looking for new wars to start.
