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.
Interstellar travel is the ability to travel between stars in the exploration of space. In science fiction, interstellar travel is often depicted as faster-than-light, such as warp drive on "Star Trek" or light speed in "Star Wars," but research is underway to build robotic probes for Alpha Centauri (as in the Breakthrough Starshot project), and to develop hibernation systems, generation ships and other long-duration space technology needed to one day send astronauts to other stars.

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.
NASA's Interstellar Boundary Explorer (IBEX) reset its flight computer Feb. 18 and has been unresponsive to commands ever since, agency officials said Friday (Feb. 24).
Reference Interstellar space is filled with atoms and molecules, 99% of which is gas, and just 1% is cosmic dust.
Two NASA astronauts will float outside the International Space Station today to prepare the orbiting lab for new solar wings and you can watch it live online.
Space.com's editors present a reading list for space and sci-fi lovers, as well as children who are interested in astronomy and spaceflight.
Launching an interstellar probe sounds exceedingly lofty, ambitious, and tough to do. But there's no need to wait for new technology, say advocates.
The community ponders about the most important questions in space exploration and interrogates dark matter.
Space is big — really big. And if you want to successfully navigate the interstellar depths of our galaxy, you're going to need some sort of reliable system.
The first people to colonize a world in another star system may have trouble describing their new home to the folks back on Earth, a recent study suggests.
Sending scientific instruments to the edge of the heliosphere, or the sun's region of influence, is like going to the edge of the fish bowl.
'Oumuamua is long gone, but it's still leaving scientists guessing. A new explanation proposes that the strange object was a "monstrous fluffy dust aggregate" produced by a busted-up comet.
The proposed "Interstellar Probe" mission would aim to reach 90 billion miles (145 billion kilometers) from the sun, pushing the limits of engineering know-how and space technology.
