BIGGEST TEST YET FOR TINY SPACECRAFT

» A

. pair of tiny experimental satellites trailing NASA’s InSight spacecraft all the way to Mars face their biggest test yet.

Their mission: Broadcast immediate news, good or bad, of InSight’s plunge through the Martian atmosphere on Monday.

Named WALL-E and EVE after the main characters in the 2008 animated movie, the twin CubeSats will pass within a few thousand miles of Mars as the lander attempts its dicey touchdown.

If the two manage to relay InSight’s radio signals to ground controllers nearly 100 million miles away, we’ll know within minutes whether the spacecraft landed safely.

» The leader of the U.N.’s atomic watchdog on Thursday called on North Korea to allow inspectors back into the country to monitor its nuclear program.

Speaking at a board meeting of the International Atomic Energy Agency, Director General Yukiya Amano noted that Pyongyang had in September talked about denuclearization measures including the “permanent dismantlement of the nuclear facilities in Yongbyon” — a reactor where it produces plutonium.

Amano said there has been activity observed at Yongbyon, but “without access the agency cannot confirm the nature and purpose of these activities.”

IAEA inspectors were expelled from North Korea in 2009, but Amano said the agency continues to prepare for their possible readmittance.
