A asteroid bigger than Egypt's Great Pyramid of Giza is due to fly by Earth for the first time in over 100 years on August 20.
The asteroid, named 2019 AV13 , is estimated to measure between around 330 feet and 750 feet in diameter—making it about the size of the 455-foot Great Pyramid.
How scientists spotted 9th target for NASA's Lucy asteroid mission | Space
In preparation for the Lucy mission to explore a distant class of asteroids called the Trojans, astronomers have been monitoring the targeted space rocks.
By comparing observations from many different locations on Earth , scientists can precisely measure the shadow an asteroid casts on a star during such an event, allowing them to precisely study the size and shape of the space rock.
Asteroid Ryugu Reveals Ancient Grains of Stardust Older Than The Solar System : ScienceAlert
A new analysis of samples of asteroid Ryugu has revealed the presence of mineral grains forged in the outflows or explosions of old stars before our own Sun formed.
As identified by previous research, these presolar grains reveal Ryugu is very similar to a class of meteorites known as Ivuna-type carbonaceous (CI) chondrites. However, the presence of some fragile grains indicate that parts of Ryugu may be unchanged since the asteroid formed.
NASA will deliberately crash a spacecraft into an asteroid next month | TweakTown
NASA is scheduled to collide a high-speed spacecraft with an asteroid in an attempt to change its orbit using a technique called a "kinetic impactor".
The mission is called the Double Asteroid Redirection Test (DART) and launched on Nov. 23, 2021, atop a SpaceX Falcon 9 rocket.
The Renaissance Of Main Belt Asteroid Science - SpaceRef
The NASA Dawn spacecraft took off from Cape Canaveral in September 2007 atop a Delta II rocket starting an ambitious journey to Vesta and Ceres, the two most massive worlds in the largest reservoir of asteroids in the Solar System, the Main Belt.
Prior to the Dawn launch, Earth-bound observations of Vesta and Ceres revealed intriguing features–from Vesta’s rugged shape to Ceres’ tenuous water exosphere–, but these objects remained fuzzy speckles of light even through the lenses of the most powerful telescopes.
Presolar Stardust In Asteroid Ryugu - Astrobiology
Image: a) Backscattered electron (BSE) image of Ryugu thin section A0058-2. Every black area consists of ~20 NanoSIMS maps measured. b) An area in section C0002 with a less-altered lithology than the surrounding Ryugu matrix ("clast 1"; BSE image).
We have conducted a NanoSIMS-based search for presolar material in samples recently returned from C-type asteroid Ryugu as part of JAXA’s Hayabusa2 mission.
NASA Has New Astronaut Trainees for Mars and Asteroid Explorations | iTech Post
NASA has eight space trainees who will train in space facilities and remote locations for missions to Mars, asteroids, and low-Earth orbit.
NASA has a new set of possible astronauts who will assist the agency explore an asteroid and Mars. Eight individuals have been chosen as NASA's latest astronaut trainees.
