Astronauts finish repairs to space station cosmic ray detector

January 25, 2020

During a fourth spacewalk Saturday to wrap up repairs of the coolant system in a $2 billion cosmic ray detector, Italian astronaut Luca Parmitano and Drew Morgan discovered a leak in one of eight coolant lines that were spliced into a new pump module during three earlier excursions. But Parmitano was able to tighten a fitting on the line and the astronauts were able to complete the repair work, setting the stage for the instrument to resume science operations.

Astronauts perform third spacewalk to fix cosmic ray detector

December 2, 2019

After prepping their patient — a $2 billion cosmic ray detector — during two earlier spacewalks, two space station astronauts ventured back outside for a third outing Monday to carry out what amounted to transplant surgery, installing replacement coolant pumps in a bid to revive the costly instrument and extend its life.

Spacewalkers continue repair of cosmic ray detector

November 22, 2019

In a complex bit of orbital surgery, two spacewalking astronauts cut into a $2 billion cosmic ray detector Friday, venting away life-sustaining carbon dioxide refrigerant and then snipping eight coolant lines the size of soda straws to prepare the high-tech “patient” for a coolant pump transplant.

Astronauts complete bonus objectives in first in series of AMS repair spacewalks

November 15, 2019

Two astronauts ventured outside the International Space Station Friday for the first of four spacewalks to repair a $2 billion cosmic ray detector, breezing through work to prep the device for invasive surgery to splice in new coolant pumps and extend the instrument’s life probing the composition of the universe.

Complex spacewalk repair work begins Friday

November 14, 2019

After four years of brainstorming, custom tool development and training, two astronauts plan to venture outside the International Space Station Friday for the first of four spacewalks to repair a $2 billion cosmic ray detector. The excursions are considered the most challenging since work to service the Hubble Space Telescope.

Repair equipment for particle physics experiment aboard next station cargo launch

November 1, 2019

Northrop Grumman’s Cygnus supply ship set for liftoff Saturday will deliver to the International Space Station the final hardware for a series of ambitious spacewalks later this month to install a new coolant system on the Alpha Magnetic Spectrometer, a $2 billion particle physics experiment seeking the cosmic signatures of dark matter and antimatter.

First all-female spacewalk on tap later this month

October 4, 2019

After a spacesuit sizing problem prevented an all-female spacewalk earlier this year, astronauts Christina Koch and Jessica Meir will get a chance to make history Oct. 21 when they venture outside the International Space Station in the fourth of five excursions to install a new set of solar array batteries, NASA managers announced Friday.

Soyuz capsule swaps docking ports on space station, clearing way for new arrival

August 26, 2019

Flying by hand, Russian cosmonaut Alexander Skvortsov undocked his Soyuz space capsule from the International Space Station late Sunday (U.S. time) and maneuvered the ship to a new parking spot on the million-pound research complex, clearing the way for the arrival of a new Soyuz spacecraft Monday night after aborting its first approach.
