Cosmic dust, not 'alien megastructure,' veils mysterious star

  Cosmic dust, not 'alien megastructure,' veils mysterious star It's been called the "most mysterious star in the universe," bigger than the sun and yet brightening and dimming in an odd way that suggested to some an alien megastructure might be circling it. But a study out Wednesday, compiled by more than 100 scientists who have been observing the star named KIC 8462852, puts the alien rumors to rest.

The water they contain could be a useful resource for future astronauts.

Massive ice sheets have been discovered on Mars that could potentially be a resource for astronauts to harness for exploration of the planet.

According to a report published on Friday in the journal Science, scientists examined eight areas on Mars where erosion has occurred. Researchers discovered massive ice sheets in the planet’s mid-latitudes that are believed to extend up to 100 meters deep and contain distinguishable layers that, “could preserve a record of Mars’ past climate,” the report says. “They might even be a useful source of water for future human exploration of the red planet.”

NASA’s Curiosity Rover On Mars Finds Weird Squiggles

  NASA’s Curiosity Rover On Mars Finds Weird Squiggles The Curiosity Rover rolling around on Mars sent photos to NASA of strange stick figures lying on Martian rocks.The rover transmitted images back to Earth of what look like squiggles left on top of a rock formation, where sand is dusted around. The space agency is looking into how they got there.

In 2005, the Mars Reconnaissance Orbiter (MRO) was launched to explore Mars. A few years ago, the $720 million spacecraft returned images and data that showed a pale sliver of blue amid the terracotta-colored dust. These images helped Colin Dundas, a geologist at the U.S. Geological Survey, and teamdiscover eight steep cliffs of what appears to be almost pure ice.

“This kind of ice is more widespread than previously thought,” Colin Dundas, a geologist at the U.S. Geological Survey, told Science.

This is not the first time ice has been found on Mars. Ice covers its poles, and the MRO has detected “signatures of thick, buried ice across the planet’s belly,” according to Science. Millions of years ago, Mars span on a different axis and in a different orbit, so some scientists say these signatures may be remnants of glaciers from then.

NASA tests small nuclear reactor that could power a habitat on Mars .
Everyone from Elon Musk to Donald Trump wants to send a manned mission to Mars in the not too distant future, but there are quite a few problems that need to be solved before we can achieve that goal. Kilopower is a small nuclear reactor that can generate a reliable power supply. Versions range from 1 kilowatt -- enough to power a basic toaster -- to ten kilowatts and Kilopower project researchers said in a Space.com article that around four or five of the latter would be needed to power a habitat on Mars.
