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.
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.
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.
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.
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.
Astronauts Drew Morgan and Christina Koch floated back outside the International Space Station Friday and completed work to replace six aging batteries with three more powerful units in one of the lab’s eight solar power circuits. Three more spacewalks are planned over the next two weeks to replace another six batteries in an adjacent circuit.
Astronauts Christina Koch and Andrew Morgan floated outside the International Space Station Sunday and completed a 7-hour, 1-minute spacewalk to begin replacing batteries on the far left side of the research outpost’s solar array truss, the first of up to six excursions scheduled before the end of October.
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.
