The Moon May Have Formed From a Molten Magma Ocean on Earth

Our moon is a strange one. Most of the moons in our solar system are captured asteroids, but ours is different. Scientists have long believed that our moon was formed when a giant asteroid crashed into the Earth billions of years ago. That impact ejected tons of debris into Earth’s orbit, where it eventually coalesced into the…

NASA Says Two of Its Rockets Failed Because of Metals Fraud

In 2009, NASA attempted to launch a weather satellite into space. Unfortunately, the rocket’s fairing failed to open and the launch failed. Now, a decade later, we finally know why: NASA says that its contractor for the fairing, Sapa Profiles, committed extensive metals fraud. Sapa Profiles was contracted to manufacture parts for the fairings on two…

Some of Earth’s Gold Came From Two Neutron Stars That Collided Billions of Years Ago

For about a century now, scientists have theorized that the metals in our Universe are the result of stellar nucleosynthesis. This theory states that after the first stars formed, heat and pressure in their interiors led to the creation of heavier elements like silicon and iron. These elements not only enriched future generations of stars (“metallicity”),…

First planetary defense technology demonstration to collide with asteroid in 2022

The Double Asteroid Redirection Test (DART) – NASA’s first mission to demonstrate a planetary defense technique – will get one chance to hit its target, the small moonlet in the binary asteroid system Didymos. The asteroid poses no threat to Earth and is an ideal test target: measuring the change in how the smaller asteroid…

NASA Is Developing ‘Soft Robots’ to Help Explore Other Worlds

Think robots are all square corners and rigid metal parts? Think again.  Two interns at NASA are part of a larger group working on “soft robots” that could be used for exploring worlds beyond Earth. This includes the moon, NASA’s next major destination for astronauts. The advantage of a soft robot is that it’s flexible and, in…

Whirling ‘Collapsar’ Stars Gave Universe Its Gold

Most of the universe’s gold, uranium and other heavy elements are generated from rapidly whirling collapsing stars, a new study finds. The universe’s three lightest elements — hydrogen, helium and lithium — were born in the earliest moments of the cosmos, just a minute or so after the Big Bang. Elements up to iron on the…

InSight Mars Lander Snaps Dusty Selfie on Red Planet

NASA’s InSight Mars lander has taken its second selfie, and the photo shows just how much has changed for the spacecraft over the past few months. InSight captured its first selfie on Dec. 6, just a week and a half after touching down on the Red Planet. In that photo, the lander looks shiny and new, and its…
