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.

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.

Giant asteroid apocalypse 13K years ago was witnessed by ancient humans, experts believe

by Chris Ciaccia, Fox News

The asteroid that hit Earth nearly 13,000 years ago and ended the Pleistocene era likely wiped out an ancient civilization in what is modern-day Syria, according to newly discovered evidence.

The research, published in Scientific Reports, notes that experts discovered remnants of glass that were created during a high-impact event, as well as minerals such as chromium, iron, nickel and others, all of which formed in temperatures higher than 2,200 degrees Celsius, according to a statement from the University of California-Santa Barbara.

SHOTS FIRED Jupiter is flinging asteroids at Earth ‘like a sniper’, top scientist warns

by Charlotte Edwards, The Sun

JUPITER is being accused of actively flinging dangerous objects into the inner solar system that could impact Earth.

Some space experts believe the huge planet protects Earth from comets and asteroids but new research has suggested that it may actually be doing the opposite.

The popular Jupiter Shield theory proposes that the planet acts like a giant space shield due to its huge mass causing it to suck in or deflect dangerous debris.

Mysterious Asteroid May Actually Be the Smallest Dwarf Planet in the Solar System

by George Dvorsky, Gizmodo

A new telescopic survey of Hygiea—the fourth largest object in the main asteroid belt—suggests it’s a dwarf planet, due to its surprisingly spherical shape.

Discovered in 1849 by Italian astronomer Annibale de Gasparis, Hygiea is located in the main asteroid belt between Mars and Jupiter. It’s the fourth largest object in the belt, with Ceres, Vesta, and Pallas being the only bigger ones (of the three, only Ceres is a dwarf planet). Despite its size, however, Hygiea has remained a poorly studied object, and it’s easily the most mysterious of the big four.
