NASA has made another bold bet on the nation's commercial space industry, this time asking private companies to provide a lunar rover that can survive for up to a decade near the South Pole of the Moon.

The space agency on Wednesday announced the selection of three teams, led by Intuitive Machines, Lunar Outpost, and Venturi Astrolab, to work on designs for a rover that can be used by astronauts and function autonomously when no crew is around.

Each company will work with the space agency for the next year or so to reach what is known as a "preliminary design review" for their vehicle. The initial awards are not huge; each is a few tens of millions of dollars. But this work will set the stage for a demonstration phase, which will be worth significantly more.

The number of partisan news outlets in the US masquerading as legitimate journalism now equals genuine local newspaper sites, researchers say, as so-called pink slime operators gear up ahead of November’s presidential election.

Pink slime sites mimic local news providers but are highly partisan and tend to bury their deep ties to dark money, lobbying groups, and special interests.

NewsGuard, which rates the quality and trustworthiness of news sites, has identified 1,197 pink slime sites operating in the US as of April 1—about as many as the estimated 1,200 real news sites operated by daily local newspapers.

In February, NASA celebrated the arrival of the first US-made lander on the Moon in more than 50 years, an achievement that helps pave the way for the return of American astronauts to the lunar surface later this decade. But the clock was ticking for Intuitive Machines' Odysseus spacecraft after touching down on February 22 near the Moon's south pole.

Each day and night on the Moon lasts two weeks. When the Sun sets, a solar-powered lunar lander like Odysseus is starved of energy. Temperatures during the lunar night plummet, bottoming out at around minus 280° Fahrenheit (minus 173° Celsius).

Over the course of two weeks, these cold temperatures can damage sensitive spacecraft equipment, killing a lander even if it could start generating power again at lunar sunrise. Surviving the night requires heat and electricity, and NASA officials say nuclear power is one of the most attractive solutions to this problem.
