NASA hopes a mission that is expected to launch next month will demonstrate a technique that could prevent an asteroid from striking Earth.
The mission, called the Double Asteroid Redirection Test, or DART, is led for NASA by the Johns Hopkins Applied Physics Laboratory.
The UAE aims to launch a probe to the asteroid belt between Mars and Jupiter in 2028 –
The United Arab Emirates (UAE) Space Agency will be sending a probe to the asteroid belt between Mars and Jupiter, with the aim of ultimately landing on an asteroid in the early 2030s, in a mission that will surely be a major boost for the country's private sector space companies.
Watch a video tour of NASA’s Lucy asteroid explorer – Spaceflight Now
Set for launch Oct. 16 on a flight to explore asteroids in the outer solar system, NASA’s Lucy spacecraft has been fueled and encapsulated inside the payload fairing of its Atlas 5 rocket.
The Lucy spacecraft is the centerpiece of a $981 million mission to visit eight asteroids, including seven located in swarms of Trojan asteroids ahead of and behind Jupiter in its orbit around the sun.
Highly porous rocks are responsible for asteroid Bennu's surprisingly craggy surface
New research, published in Nature and led by mission team member Saverio Cambioni, used machine learning and surface temperature data to solve the mystery.
"The 'REx' in OSIRIS-REx stands for Regolith Explorer, so mapping and characterizing the surface of the asteroid was a main goal," said study co-author and OSIRIS-REx principal investigator Dante Lauretta, a Regents Professor of Planetary Sciences at the University of Arizona.
Asteroid 16 Psyche: Shape, Features, and Global Map - SpaceRef
We develop a shape model of asteroid 16 Psyche using observations acquired in a wide range of wavelengths:
Arecibo S-band delay-Doppler imaging, Atacama Large Millimeter Array (ALMA) plane-of-sky imaging, adaptive optics (AO) images from Keck and the Very Large Telescope (VLT), and a recent stellar occultation.

Research Says Nuclear Blast Effective For Late-Stage Asteroid Impact
A new space study has revealed that using a nuclear disruption method is an effective solution in an emergency scenario where an asteroid is in the late stages of a collision course with Earth.
Another version of the strategy is sending a spacecraft into space and ramming it against the asteroid to knock it off course. NASA is actually testing this approach as part of its DART planetary defense project.
Asteroids with Highly Porous Rocks Lack Fine-Grain Regolith: Study | Sci-News.com
Planetary researchers have discovered an inverse correlation between the local abundance of fine-grain material and the porosity of rocks on the carbonaceous asteroid (101955) Bennu .
This mosaic image of asteroid Bennu is composed of 12 images collected on December 2, 2018 by OSIRIS-REx's PolyCam instrument from a range of 15 miles (24 km). Image credit: NASA / NASA's Goddard Space Flight Center / University of Arizona.

Mehdi Hoseinivand Aalipour's affectionate first film observes the tender bonds of one Iranian family
Hoseinivand Aalipour has enjoyed a lengthy career as an editor of features and television series, a documentarian and the maker of short films. That shows in a first feature that is made with the assurance of experience.
Nuking Asteroid Similar to Armageddon Could be "Very Effective" According to Report
Michael Bay's 1998 disaster-thriller Armageddon needs no introduction at this point.
In a new report featured on Science Alert, it seems that a "late-time small-body disruption" defense system of Earth is actually a viable strategy against incoming asteroids.
According to physicist Patrick King of John Hopkins University Maryland: "One of the challenges in assessing disruption is that you need to model all of the fragment orbits, which is generally far more complicated than modeling a simple deflection.
