Unexpected Discoveries: NASA Planetary Radar Images Reveal Asteroid As It Approaches Earth

  • No comments
During asteroid 2008 OS7's final approach to Earth on February 2, 2024, the agency's Deep Space Radar collected the first detailed images of the stadium-sized asteroid
When the DART spacecraft crashed into the dimorphous asteroid, the body of the spacecraft hit between two large rocks and the two solar panels hit the rocks themselves. The yellow surface is a digital ground model of the impact site prepared from DART images, and the image of the DART spacecraft shows its position a few tens of milliseconds before impact. The white line coming out of the back of the spacecraft shows the trajectory of the spacecraft. The length of the spacecraft's body was about 1.30 meters from front to back.

In a scientific article published this week in the journal NATURE there is a detailed report on the successful demonstration of the kinetic impactor technology by DART: a reconstruction of the impact itself, a report on the timeline until the impact, detailing the location and nature of the impact site, and the documentation of the size and shape of Dimorphus

When cinema and reality come together in the mission of dropping an asteroid: the DART spacecraft is launched

  • No comments
The DART spacecraft that will try to change the orbit of a double asteroid will be launched on 24/11. The producers of Netflix's space disaster film "Don't Look Up," about the discovery of an Earth-threatening asteroid, have scheduled its arrival on Netflix for its scheduled launch day

One of the researchers responsible for the discovery tells how an asteroid similar to the one that caused the incident in Tungaska in Siberia in 1908, hit a city in Jordan northeast of the Dead Sea. The city was abandoned afterwards, and the echoes of the explosion hit other cities in the vicinity, including Jericho

From the artist's illustration above, you can get an impression of how nearby objects will look to the NEO Surveyor. Their faint heat signatures will appear as a band of dots that appear in red in this image, for our convenience. That way they will look different from the stars in the background, which are painted blue in the picture. Hunting for near-infrared objects will also allow scientists to determine not only the location and orbit of the objects but also their size. And it is the size that determines the extent of their destruction if they hit the Earth. Image: NASA
