Evidence of water movement found in meteorites that recently hit the earth

Evidence of water movement found in meteorites that recently hit the earth

A team of international researchers has discovered evidence of recent water movement in meteorites that recently impacted the earth. The researchers looked at carbonaceous chondrite (CC) meteorites that impacted the surface of the planet within the past 100 years. The discovery of evidence of recent water movement is significant because many scientists believe water present on the Earth came from meteorites.

NASA Lucy mission integrates its second scientific instrument

NASA Lucy mission integrates its second scientific instrument

The first NASA mission to the Trojan asteroids is called Lucy. The spacecraft is closer to launch after the Lucy team integrated its second scientific instrument called L'TES, or Lucy Thermal Emission Spectrometer. When complete, the spacecraft will have three scientific instruments, and Lucy project manager Donya Douglas-Bradshaw says having two of the three instruments integrated is an exciting milestone.

Harvard professor believes bizarre asteroid from 2017 was alien technology

Harvard professor believes bizarre asteroid from 2017 was alien technology

A Harvard professor named Avi Loeb, the chair of Harvard's Department of Astronomy, believes the first sign we will get of an alien intelligence won't be spacecraft. Rather he thinks the first sign we will get of extraterrestrial life will be the civilization's trash. Loeb has a book being published on January 26 that lays out a case for why a bizarre asteroid that entered our solar system in 2017 was a piece of alien technology.

Unique meteorite hints at parent asteroid lurking in our solar system

Unique meteorite hints at parent asteroid lurking in our solar system

Researchers have been conducting a study on a mysterious meteorite that exploded over Sudan in 2008. The meteor was estimated by NASA to weigh about nine tons and to be nearly 13-foot in diameter when it was spotted before impact. After the meteorite entered the atmosphere and impacted the planet's surface, researchers went to the Sudanese desert to collect its remains for study. One of those fragments suggests that the meteor likely broke off from a massive asteroid approximately the size of the dwarf planet Ceres.

Scientists discover a superhighway network to travel the solar system

Scientists discover a superhighway network to travel the solar system

Researchers have discovered what they describe as a new superhighway network to travel the solar system much faster than previously thought possible. Scientists say that these routes can push comets and asteroids close to the distance between Jupiter and Neptune in under a decade. The speedy paths can also move comets and asteroids 100 astronomical units in less than a century.

JAXA’s Hayabusa2 successfully delivers Ryugu asteroid dust to Earth

JAXA’s Hayabusa2 successfully delivers Ryugu asteroid dust to Earth

Over the weekend, the Japan Aerospace Exploration Agency (JAXA) successfully delivered asteroid dust to Earth, a milestone mission that will help scientists explore the origins of the 'ancient grains,' according to NASA. JAXA's Hayabusa2 spacecraft successfully landed on the asteroid Ryugu in 2019 and collected dust samples later that year.

JAXA’s Hayabusa2 will return its samples to Earth today

JAXA’s Hayabusa2 will return its samples to Earth today

The Japan Aerospace Exploration Agency (JAXA) has been working on its Hayabusa2 mission for a long time. Late last month, we mentioned that the spacecraft was nearing home and preparing to drop off its samples from on and under the surface of an asteroid called Ryugu. Today is the day samples will be returned.

Hayabusa2 is getting close to home with its samples

It's been a long time since we talked about the Japanese spacecraft Hayabusa2. About a year ago, Hayabusa2 landed on the asteroid Ryugu about 180 million miles away from Earth. The spacecraft is now very close to returning home with samples for further analysis.

Scientists can’t eliminate the possibility that asteroid Apophis will hit the Earth

Scientists can’t eliminate the possibility that asteroid Apophis will hit the Earth

Many asteroids are floating around in space that NASA and other organizations are tracking. One of those asteroids is about the size of the Eiffel Tower and is called Apophis. Scientists recently said that they couldn't rule out that Apophis might impact the Earth in 2068.

Earth has captured a new satellite for at least a few months

Earth has captured a new satellite for at least a few months

The Earth has captured something interesting in its gravity that will orbit our planet for a few months before it escapes and ultimately ends up in a solar orbit. The object it has captured isn't an asteroid. It's believed to be the Centaur upper stage rocket booster that helped pushed Surveyor 2 toward the moon in 1966. The object was first detected by the Pan-STARRS1 survey telescope on Maui in September.

The telescope noticed that the object followed a slightly but distinctly curved path in the sky, which was a sign of its proximity to the earth. The observed curvature is due to the observer's rotation around the Earth's axis as the planet spins. Initially, the object was believed to be an asteroid orbiting the sun and was given a standard designation by the Minor Planet Center of 2020 SO.

NASA says OSIRIS-REx Bennu sample collection effort is finally over

NASA says OSIRIS-REx Bennu sample collection effort is finally over

After a few days of effort, NASA has confirmed that its OSIRIS-REx spacecraft has secured its Bennu asteroid sample payload, meaning that scientists will eventually get their hands on a pure few ounces of asteroid regolith. The news follows NASA's statement that though the Bennu touchdown and sampling event had been a success, some of the sampled material was leaking from a gap in the collection vessel.

Asteroid 16 Psyche is possibly worth $10,000 quadrillion dollars

The Hubble Space Telescope discovered an asteroid in the main asteroid belt between Mars and Jupiter called 16 Psyche. The asteroid is approximately 230 million miles from Earth and is 140 miles across. Those dimensions make the asteroid roughly the size of West Virginia.
