NASA doing the impossible – repairs a non serviceable instrument outside ISS

On 25 th (Day before yesterday) , the astronauts aboard the International Space Station completed a 6 hour spacewalk to repair an instrument which was previously considered unserviceable. Astronauts Andrew Morgan from NASA and Luca Parmitano from European Space Agency were involved in this task to repair the Alpha Magnetic Spectrometer (AMS).

The AMS was installed back in 2011 for a cost of $2 billion. But the instrument was designed to last only 3 years. This was to be shut down after its lifetime of 3 years. So it was not designed to be serviced by anyone. But because of it’s proven value researching dark matter, NASA decided to attempt repairing it.

Since this instrument was not intended to undergo standard services , the procedure was different than the standard service or repair procedures. This required training astronauts on entirely new procedures. New tools which were different than ones used in standard spacewalks were introduced.

NASA has released a live recording of the entire 6 hours on YouTube. This video, which is a 7 hour video, can be viewed below.
