One big step for 3D printing tech in space


Made in Space, an extra-terrestrially focused 3D printing company, successfully completed its first extended test of its printing capabilities in a space-like environment — a huge step forward for the technology, per Scientific American.

  • What happened: Made in Space built multiple objects, including a nearly 3-foot-long beam, inside a NASA thermal vacuum chamber (think: the environment of space but with Earth's gravity).
  • The goal: This 3D printing capability is just a part of a larger Made in Space system called the Archinaut, which they hope will be able to use autonomous robotic arms to assemble structures in space.
  • Why it matters: Space exploration is currently limited by the exorbitant costs of transporting Earth-built spacecraft skyward, but Made in Space's technology would significantly reduce those barriers to entry — allowing for larger, more complicated structures to be built off-Earth.

Major U.S. cities have implemented curfews and called on National Guard to mobilize as thousands of demonstrators gather across the nation to continue protesting the death of George Floyd.

The state of play: Hundreds have already been arrested as tensions continue to rise between protesters and local governments. Protesters are setting police cars on fire as freeways remain blocked and windows are shattered, per the Washington Post. Law enforcement officials are using tear gas and rubber bullets to try to disperse crowds and send protesters home.

President Trump told reporters on Saturday evening he would postpone the G7 summit to September and expand the meeting to more nations that are not members of the Group of 7.

Details: Trump said he would invite Russia, South Korea, Australia and India to the summit, according to a pool report. "I don’t feel that as a G7 it properly represents what’s going on in the world. It’s a very outdated group of countries," he said.

George Floyd protests: What you need to know

Curfews are being imposed in Portland, Oregon, and Cincinnati, while the governors of Georgia, Kentucky, Ohio and Texas activated the National Guard following unrest in the states, per AP.

The big picture: Floyd's fatal run-in with police is the latest reminder of the disparities between black and white communities in the U.S. and comes as African Americans grapple with higher death rates from the coronavirus and higher unemployment from trying to stem its spread.
