The term "hypervelocity" refers to velocities in the range from a few kilometers per second to some tens of kilometers per second. This is especially relevant in the field of space exploration and military use of space, where hypervelocity impacts (e.g. by space debris or an attacking projectile) can result in anything from minor component degradation to the complete destruction of a ...
In late 2019 the Kiso Observatory added a new instrument to the telescope, "Tomo-e Gozen", designed to detect fast moving and rapidly changing objects. It has a wide field of view (20 square degrees ) and scans the sky in just 2 hours, far faster than any other survey as of 2021.
An asteroid that crashed into the Earth’s atmosphere over the UK and France was spotted just hours before it crashed. The world was given only seven hours warning that it was being approached by ...
After having been slowed by the Earth's atmosphere, the meteorite was traveling at approximately 164 miles per hour (264 km/h) at impact. The Peekskill meteorite smashed through the trunk of a red 1980 Chevrolet Malibu [ 10 ] and narrowly missed the gas tank, finally coming to rest in an impact pit beneath the car.
This mosaic image shows the asteroid Bennu, composed of 12 PolyCam images collected on December 2, 2018 by the OSIRIS-REx spacecraft from a range of 15 miles (24 km).
A newly discovered asteroid named 2024 YR4 now has a 2.2% chance of affecting Earth in 2032 after recent observations.
A meteorite crashed in the area of Mission, Texas, Wednesday night causing a loud boom that startled residents, authorities said. Meteorite crashes in South Texas causing startling boom ...
The average velocity of micrometeoroids relative to a spacecraft in orbit is 10 kilometers per second (22,500 mph). Resistance to micrometeoroid impact is a significant design challenge for spacecraft and space suit designers ( See Thermal Micrometeoroid Garment ).
