Astronautas reparan espectr metro

Two astronauts installed new cooling pumps on a cosmic ray detector outside the International Space Station. This was the third spacewalk in three weeks for Luca Parmitano and Andrew Morgan, culminating years of work to repair the magnetic spectrometer. The spectrometer, valued at $2 billion, has been in space for over eight years searching for antimatter and dark matter. NASA likened the series of spacewalks to heart surgery due to their complexity. A fourth spacewalk is planned to check for leaks and install a thermal cover.

What was the primary task of the astronauts during the spacewalk?

• Installing new solar panels

• Repairing the space station's communication system

• Installing new cooling pumps on a cosmic ray detector

• Conducting a spacewalk for training purposes

How long has the spectrometer been in space?

• Five years

• Twelve years

• Eight and a half years

• Ten years

What is the primary purpose of the spectrometer?

• To study the sun's radiation

• To search for antimatter and dark matter
