New Mars crater exposes mysterious darker material

New Mars crater exposes mysterious darker material The Red Planet was hit by an asteroid sometime within the past three years and the resulting crater has exposed a "darker material" underneath Mars' reddish dust that is currently perplexing scientists. The image was captured by the High-Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter on April 17, 2019. The black-and-blue area on the Martian landscape highlights the area that was hit. University of Arizona scientist Veronica Bray told Space.

Reactor for Mars Colony Could Be Ready in 3 Years . “We want a power source that can handle extreme environments,” said Lee Mason, NASA’s principal technologist for power and energy storage in January 2018, when a Kilopower passed a test with flying colors.

"I think we could do this in three years and be ready for flight," McClure said late last month during a presentation with NASA's Future In-Space A crewed Mars outpost will have considerably higher energy demands than that: around 40 kilowatts of continuously available electrical power (40 kWe)

An experimental miniature nuclear reactor known as Kilopower, meant to power manned outposts beyond Earth, could be ready for an in-flight test as early as 2022, says a project lead project at the Department of Energy's (DOE) Los Alamos National Laboratory in New Mexico.

In a recent NASA Future In-Space Operations (FISO) Working Group weekly teleconference, Kilopower lead Patrick McClure spoke for himself and not the government when he said, "I think we could do this in three years and be ready for flight."

A single Kilopower, which is part of NASA's Game Changing Development (GCD), could proffer 10 kilowatts of electrical power, which is enough to power multiple average homes. NASA predicts that 4 Kilopower units could be the energy source for a manned outpost continuously for at least 10 years.

In July this year , the Earth and Mars will come closer than at any other point in the last 15 years . Fake mission to Mars leaves astronauts spaced out . So, will we be ready in 15 years ? There will be no way to truly know until we do it. But these could still easily be penetrated by any high- powered rays.

“We want a power source that can handle extreme environments,” said Lee Mason, NASA’s principal technologist for power and energy storage in January 2018, when a Kilopower passed a test with flying colors. “Kilopower opens up the full surface of Mars, including the northern latitudes where water may reside. On the moon, Kilopower could be deployed to help search for resources in permanently shadowed craters.”

The prototype, known as KRUSTY (yes, it's really a Simpsons reference), held within it a solid, cast uranium-235 reactor core and was around the size of a roll of paper towels. "Passive sodium heat pipes transfer reactor heat to high-efficiency Stirling engines, which convert the heat to electricity," NASA explained at the time.

On the teleconference, McClure went into detail about the knowledge gained from the KRUSTY tests. The Kilopower's main competition comes from current space power generators known as radioisotope thermoelectric generators (RTGs), which powered spacecraft as far back as the Voyager missions. RTGs, which are also mini-nuclear reactors, are able to convert around 7 percent of fission heat they give off into electricity.

The KRUSTY, on the other hand, was able to give off 30 percent. "This was an extremely successful test," McClure said.

Of course, projects can get delayed for a variety of reasons, from accidents to poor construction. NASA need not look any further than the James Webb Space Telescope to see how a complex project can become a delayed slog.

Currently, NASA's official roadmap to manned outposts on other worlds has the timeline set for the 2030s. If both timelines hold, then one of the biggest challenges facing life on Mars—power—could have an answer soon.
