A rocket made almost entirely of 3D-printed parts remained on the pad Wednesday after its debut launch attempt was aborted at the last minute.

California-based Relativity Space was attempting to launch the rocket to orbit from a former missile site at Cape Canaveral Space Force Station.

Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory are leading a new effort to land a radio telescope on the moon. If successful, the project will mark the first step towards exploring the Dark Ages of the universe.

The Dark Ages are an early era of cosmological history starting about 380,000 years after the Big Bang. There were no stars or planets in the Dark Ages. It's a point in time that scientists have never been able to observe.

An ensemble of microscopes, medical-style equipment, and other 3D scanners is providing insights that could help human and robotic explorers survive the harsh environments of deep space, the moon, Mars and beyond.
