Northrop Grumman’s Cygnus provides ship set for liftoff will ship to the International Space Station the ultimate hardware for a collection of formidable spacewalks later this month to put in a brand new coolant system on the Alpha Magnetic Spectrometer, a $2 billion particle physics experiment searching for the cosmic signatures of dark matter and antimatter. The new coolant system, together with specifically-constructed spacewalking instruments, are stowed contained in the automated Cygnus cargo craft awaiting liftoff Saturday at 9:59 a.m. EDT (1359 GMT) from Wallops Island, Virginia.
The AMS restore tools are a part of some 8,200 kilos (3.7 metric tons) of cargo loaded contained in the Cygnus provide ship on top of a two-stage Antares booster. European Space Agency astronaut Luca Parmitano and NASA flight engineer Andrew Morgan will carry out the spacewalks to restore the AMS instrument. The complicated repairs are anticipated to require four or five spacewalks to finish, starting in mid-November.
Mounted on the house station’s truss on the penultimate area shuttle mission in 2011, the Alpha Magnetic Spectrometer is successfully a strong magnet that pulls cosmic rays, subatomic particles touring by means of space at practically the speed of light.
Three of the four coolant pumps on AMS’s silicon tracker, which measures the trajectory and vitality of the cosmic rays captured by the instrument, have failed, prompting NASA engineers to develop a plan to restore the coolant system.
Led by Samuel Ting, a Nobel laureate from the Massachusetts Institute of Expertise, the worldwide science staff behind the Alpha Magnetic Spectrometer is eager to obtain new knowledge from the instrument to see if tendencies from the first eight years of observations proceed. AMS has detected greater than 140 billion cosmic ray particles thus far, cataloging their mass, velocity, cost, and path of journey.
