This robot constructs buildings from moon dust, ice and dirt

A new robot designed by a research affiliate at MIT can digitally construct buildings out of local materials ranging from ice to dirt to moon dust.

Why it matters: The Digital Construction Platform (DCP) is revolutionizing construction by proving that new technology can source local energy and materials to autonomously manufacture buildings — all while adapting to local conditions. This is particularly helpful in disaster relief situations and hazardous environments.

How it works: DCP is basically a giant, solar-powered, four-ton robotic arm (that you'd typically see on an assembly line) that sits atop tank tracks. It zips around collecting data about its surroundings, like radiation levels and topography, using the sensors in its technology. The arm has a nozzle that can mix various local, viscous materials and spray them to create structures.

The timing: Because of the DCP's solar panels, it can operate for eight hours after one charge. It can be powered up and ready to go in just minutes.

The results: The DCP constructed a 50-foot wide dome from stock-insulating foam spray in 13.5 hours.

Who it could replace: This robot could change architects' jobs by replacing contractors who would typically do things like wiring or HVAC before the building construction could begin.

One fun thing: Steven Keating, the DCP's creator, wrote that the technology would aid in "autonomous construction systems" for use in "extraterrestrial exploration," like building things from ice on Mars. "We've shown how we could do [it]," Keating told Fast Company. "And NASA is very excited to use ice for printing on Mars because ice absorbs a lot of cosmic radiation."

Esper catches White House off guard with opposition to military use, photo op

Defense Secretary Mark Esper said at a press briefing Wednesday that he does not currently support invoking the Insurrection Act, an 1807 law that permits the president to use active-duty troops on U.S. soil, in order to quell protests against racial injustice.

Why it matters: President Trump threatened this week to deploy military forces if state and local governments aren't able to squash violent protests. Axios reported on Tuesday that Trump is backing off the idea for now, but that he hasn't ruled it out.

Updates: George Floyd protests continue for 9th day

Largely peaceful protests over the death of George Floyd and other police-related killings of black people continued Wednesday, marking nine straight days of demonstrations.

The latest: As several major cities moved to lift curfews, NYPD officers "aggressively" dispersed large crowds in Brooklyn and Manhattan beyond New York City's 8 p.m. curfew, per the New York Times. The National Guard was stationed outside many protests Wednesday night, including in Hollywood and Atlanta.

Trump hits back at Mattis: "I gave him a new life"

President Trump unloaded on his former defense secretary via Twitter on Wednesday, hours after James Mattis condemned him for making a "mockery of our Constitution" in his response to mass protests in the wake of George Floyd's killing.

What he's saying: "Probably the only thing Barack Obama & I have in common is that we both had the honor of firing Jim Mattis, the world’s most overrated General. I asked for his letter of resignation, & felt great about it. His nickname was 'Chaos', which I didn’t like, & changed it to 'Mad Dog'"
