Astronauts make complex spacewalks to fix cosmic ray detector

Two International Space Station (ISS) astronauts are completing a spacewalk today to correct a dark matter experiment and you can do the live repair operation on NASA TV.

At 6:39 am, Expedition 61 commander Luca Parmitano (European Space Agency) and NASA flight engineer Andrew Morgan left the space station to replace a cooling system on the Alpha Magnetic Spectrometer (AMS), a lightning detector. cosmic. This is the first spacewalk in a series of many that will fix the experiment, which was built to find dark matter in space, noted.

Parmitano is wearing the red-striped suit and helmet camera # 11, while Morgan is wearing the non-striped suit and helmet camera # 18.

The first spacewalk will involve the two astronauts, positioning materials, removing debris cover in AMS, and placing the handrails in preparation for the next spacewalks. Astronauts are expected to complete tasks in approximately six and a half hours.

According to NASA, AMS is a joint effort between NASA and the Department of Energy's Office of Science. AMS has been capturing high-energy cosmic rays so researchers can answer important questions about antimatter, the invisible "dark matter" that makes up most of the mass of the universe, and the strange dark energy responsible for the expansion of the cosmos.

NASA has not yet shared a date for the second walk in the AMS repair space.
