This Engine Could One Day Save Us From Planetary Disaster

by Jennifer Leman, Popular Mechanics

Didymos, a 2,650-foot-wide asteroid, has an atypical cosmic companion— a 535 foot-wide satellite named Didymoon (10). These new two celestial bodies are not making a dangerous rendezvous with Earth, but they do provide an interesting opportunity for an apocalyptic dress rehearsal.

NASA and ESA’s Double Asteroid Redirection Test (DART) will head to Didymos, to knock Didymoon off course. Along with its six picture-snapping Italian Space Agency cubesats, the mission will also send a follow-up ESA spacecraft named Hera to definitively answer if we can manipulate the trajectory of Earth-bound asteroids.

Scientists Find a Superconductor in Bits of Meteorite

by Ryan F. Mandelbaum, Gizmodo

Scientists have detected trace amounts of superconducting material inside one of the world’s largest meteorites, according to a new study.

Superconductors are materials that can conduct electrical current without resistance, and they’re coveted by researchers who study quantum computers and companies hoping to transfer energy more efficiently. The superconductor inside the Australian meteorite is a known material, but the discovery itself comes as a shock.

Giant Freshwater Reserve Discovered Deep Under The Seabed Off New Zealand

by David Nield, Science Alert

A rare freshwater reserve has been discovered underneath the sea off the coast of the South Island of New Zealand, which could help head off future droughts and mitigate the impact of climate change in the coming years.

The offshore freshened groundwater (OFG) was discovered through a combination of seismology and electromagnetic wave scanning techniques, which were used to build up a 3D map of the aquifer under the sea.

Earth’s Mini-Moon Has Stopped Orbiting And Started Chasing Our Planet Instead

by Eric Mack, Forbes

For a short time, our planet was orbited by a second, tiny natural satellite. But now one veteran observer says that Asteroid 2020 CD3 has been “tossed back into orbit around the sun” and is tailing us on our annual journey around our star.

The small asteroid is probably only about the size of a large appliance or a compact car and it was first spotted in February, but astronomers think it was probably stuck in orbit around Earth for at least a year, if not longer.

Using Zoom while working from home? Here are the privacy risks to watch out for

by Rae Hodge, c|net

Don’t let tattle-tale software features disrupt your remote workflow.

Now that you’ve finished choosing your custom Zoom background, mercifully sparing your fellow workers-from-home the sight of a growing pile of gym socks behind your desk, you might think you’ve got a handle on the conference call software du jour. Unfortunately, there are a few other data security considerations to make if you want to hide your dirty laundry.
