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.
The head-on impact of the 500 kilograms (1,100 lb) [74] DART spacecraft at 6.6 kilometres per second (4.1 mi/s) [75] or 22,530 kilometres per hour (14,000 mph) [76] likely imparted an energy of about 11 gigajoules, the equivalent of about three tonnes of TNT, [77] and was expected to reduce the orbital velocity of Dimorphos between 1.75 cm/s ...
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 ...
A Belgian-Dutch team of scientists says it has created the first “treasure map” showing where meteorites may be found On the hunt for meteorites, researchers look to a data-based 'treasure map ...
The Grand Canyon in Arizona is one of Earth's natural wonders, carved out over millions of years by the gradual erosion power of the Colorado River. Close to the moon's south pole are two canyons ...
The principle of the kinetic impactor mitigation method is that the NEO or Asteroid is deflected following an impact from an impactor spacecraft. The principle of momentum transfer is used, as the impactor crashes into the NEO at a very high velocity of 10 km/s (36,000 km/h; 22,000 mph) or more.
Velaidum reports that he was standing at that location minutes before the meteorite struck it; he considers the event "a near-death experience". [4] The meteorite came from the asteroid belt, according to the University of Alberta researcher, and would have traveled at least 200 kilometres per hour (124 mph) just prior to impact. [4] [2]
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 ...
