Fungi piggybacking on space missions is dangerous to astronaut health and spacecraft equipment, but studying its behavior is also useful for long-term space missions.

NASA's Voyager 2 spacecraft had a communication breakdown with Earth, but has now resumed regular communications thanks to the agency's Deep Space Network.

NASA's Voyager 2 spacecraft is alone drifting through interstellar space after a communications breakdown left it unable to receive commands or transmit data back to Earth.

The reels are not much to look at and the quality of their recordings exists in other formats. Their pedigree, though, is unique, which is why they could be worth 10 times their weight in gold.

NASA's Interstellar Boundary Explorer (IBEX) is back to normal operations after controllers successfully reset its computer March 2, NASA said.
