A NASA spacecraft is scheduled to slam into an asteroid, in an unprecedented test designed to prevent potentially devastating collisions with Earth.
NASA’s Double Asteroid Redirection Test (DART) spacecraft will hit the asteroid Dimorphos about 11 million kilometres from Earth on Monday, attempting to slightly alter its trajectory in a test of the world’s first planetary defence system.
“This is a challenging test, and this is why we’re taking these first steps now to develop this technology before we need it,” Nancy Chabot, the mission coordination lead, told Al Jazeera just hours before the scheduled impact.
