Planetary Defense Has New Tool in Weather Satellite Lightning Detector

NASA’s efforts to better understand asteroid impacts has found unexpected support from a new satellite sensor designed to detect lightning. New research published in the journal Meteoritics and Planetary Science finds that the new Geostationary Lightning Mapper, or GLM, on two weather satellites is able to pick up signals of meteors in Earth’s atmosphere.

Capture an asteroid, bring it back to Earth?

Next time when your kids ask you to bring them a star from the sky, you don’t have to shrug and walk away. Tell them to wait, instead.

A group of Chinese scientists are mulling a bold idea to capture a small near-Earth asteroid, which might be a potential threat,

Twenty Years of Planetary Defense

NASA’s Center for Near-Earth Object Studies Enters Third Decade. On March 11, 1998, asteroid astronomers around the world received an ominous message: new observational data on the recently discovered asteroid 1997 XF11 suggested there was a chance that the half-mile-wide (nearly one kilometer) object could hit Earth in 2028.

The message came from the Minor Planet Center,

Cosmic Double Take: Rare Binary Asteroid Discovered Near Earth

Surprise — it’s twins!

That’s the realization that struck astronomers in June after they set out to study a near-Earth asteroid called 2017 YE5, which NASA today (July 12) announced is actually two asteroids, a pair of objects orbiting each other.

The bouncing-baby asteroids were revealed by three radar telescopes,

Two asteroids zipped by Earth hours before anyone noticed

By Eric Mack

The bus-sized pieces of space debris whipped by us at relatively close range over the weekend.

They almost snuck by undetected, but two small asteroids were discovered over the weekend just hours after they whizzed past us about 72,000 miles away — about one-third the distance to the moon.

Fragment of Impacting Asteroid Recovered in Botswana

A meteorite was found in Botswana’s Central Kalahari Game Reserve (CKGR) that is a fragment of asteroid 2018 LA. This small asteroid was discovered in space by the University of Arizona’s Catalina Sky Survey on June 2, 2018, eight hours before hitting Earth. The asteroid burst through the upper atmosphere and resulted in a meteor fireball.

New Mystery Discovered Regarding Active Asteroid Phaethon

Based on a new study of how near-Earth asteroid Phaethon reflects light at different angles, astronomers think that its surface may reflect less light than previously thought. This is an exciting mystery for the recently approved DESTINY+ mission to investigate when it flies past Phaethon.

The way an object reflects light depends not only on its albedo (the percentage of light it reflects) but also on the illumination angle.

Mapping the Threat of Small Near-Earth Asteroids

Just recently, a small asteroid lit up the sky over Botswana – having been discovered mere hours before it hit the Earth. Near-Earth objects (NEOs) like asteroids were the focus of a four-week conference at the Munich Institute for Astro and Particle Physics (MIAPP) in Garching.

Dr. Detlef Koschny,

Meteor explodes unexpectedly over Russia

A fireball lit up the sky above the city of Lipetsk in western Russia last week. This week, videos of the exploding meteor emerged and small meteorite fragments were found on the ground.

NASA and its scientists are part of an international effort to identify and track potentially dangerous near Earth objects,

Japan space probe reaches asteroid in search for origin of life

A Japanese probe has reached an asteroid 300 million kilometres away to collect information about the birth of the solar system and the origin of life after a more than three-year voyage through deep space.

The Hayabusa2 probe successfully settled into an observation position 20 kilometres (12 miles) above the Ryugu asteroid,
