Space Debris

Space | Analysis 2 September 2021 By Jonathan O’Callaghan The growing space junk problem could get worse with anti-satellite weapons Frame Stock Footage/Shutterstock Today there are an estimated 18,000 pieces of trackable space junk in Earth’s orbit, which includes anything larger than a tennis ball. The largest group of these…

WHEN AMATEUR IRISH astronomer John Flannery first took an interest in the hobby as a child, space was a much cleaner place than it is in 2021. Thanks to human activity, there are now hundreds of thousands of man-made objects ranging from satellites — some ‘live’ and some ‘dead’ —…

Fujitsu’s…

Teaching and learning English creates an opportunity for the U.S. to foster interaction among foreign audiences about American values and culture. For this reason, English language is the focus of one of the five core programs that support the vision of American Spaces to connect the world with the U.S.…

Astroscale hit a major milestone Wednesday, when its space junk removal demo satellite that’s currently in orbit successfully captured and released a client spacecraft using a magnetic system. The End-of-Life Services by Astroscale-demonstration (ELSA-d) mission was launched in March, with the goal of validating the company’s orbital debris removal tech.…
