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.

Detector trouble expected to delay ESA’s Euclid dark energy mission

October 23, 2017

Technical problems discovered during ground testing of U.S.-built detectors for the European Space Agency’s Euclid astronomy mission will delay the completion of the telescope’s scientific payload, jeopardizing the observatory’s 2020 launch target, the head of NASA’s astrophysics division said last week.

NASA moves forward with mission using spy satellite telescope

February 18, 2016

NASA has formally approved plans — a year ahead of schedule — for an infrared space telescope launching around 2024 to record unique wide-angle views of the cosmos, seeking answers to questions about mysterious dark energy and searching for habitable worlds around other stars.

NASA’s next flagship space telescope to get formal start

January 13, 2016

NASA officials expect to officially kick off development in February of a multibillion-dollar observatory recycling a grounded top secret spy satellite telescope capable of studying dark energy and directly resolving planets around other stars.

China sends dark matter probe into orbit

December 17, 2015

China launched the first in a series of planned space science probes Thursday, putting a satellite into orbit to study high-energy cosmic rays for signals that could hint at hypothesized clumps of dark matter that have eluded detection for decades.
