A web app from Neal.Fun is a choose-your-own-adventure for planetary annihilation.
Hundreds of thousands of asteroids lurk in our solar system, and while space agencies track many of them, there's always the chance that one will suddenly appear on a collision course with Earth. A new app on the website Neal.fun demonstrates what could happen if one smacked into any part of the planet.
Neal Agarwal developed Asteroid Simulator to show the potentially extreme local effects of different kinds of asteroids. The first step is to pick your asteroid, with choices of iron, stone, carbon, and gold, or even an icy comet. The asteroid's diameter can be set up to 1 mile (1.6 kilometers); its speed can be anywhere from 1,000 to 250,000 miles per hour; and the impact angle can be set up to 90 degrees. Once you select a strike location on a global map, prepare for chaos.

HAARP conducted a run-through on that date to prepare for the Dec. 27 asteroid bounce experiment.
The High-frequency Active Auroral Research Program research site in Gakona will transmit radio signals to asteroid 2010 XC15, which could be about 500 feet across. The University of New Mexico Long Wavelength Array near Socorro, New Mexico, and the Owens Valley Radio Observatory Long Wavelength Array near Bishop, California, will receive the signal.
This will be the first use of HAARP to probe an asteroid.
"What's new and what we are trying to do is probe asteroid interiors with long wavelength radars and radio telescopes from the ground," said Mark Haynes, lead investigator on the project and a radar systems engineer at NASA's Jet Propulsion Laboratory in Southern California. "Longer wavelengths can penetrate the interior of an object much better than the radio wavelengths used for communication."
Knowing more about an asteroid's interior, especially of an asteroid large enough to cause major damage on Earth, is important for determining how to defend against it.
"If you know the distribution of mass, you can make an impactor more effective, because you'll know where to hit the asteroid a little better," Haynes said.
Many programs exist to quickly detect asteroids, determine their orbit and shape and image their surface, either with optical telescopes or the planetary radar of the Deep Space Network, NASA's network of large and highly sensitive radio antennas in California, Spain and Australia.

This bright meteor was recorded in the framework of the SMART project, operated by the Southwestern Europe Meteor Network (SWEMN) from the meteor-observing stations located at La Hita (Toledo), Calar Alto, Sierra Nevada, La Sagra (Granada), and Sevilla. The event has been analyzed by the principal investigator of the SMART project: Dr. Jose M. Madiedo, from the Institute of Astrophysics of Andalusia (IAA-CSIC).
This video, which was filmed yesterday (December 15), shows a meteorite illuminating the night sky and falling on the ground like a "fireball" in Jinhua, Zhejiang province. No injury was reported.
The fireball seen from a dash cam video crossed the sky for just a few seconds and fell far away while burning, with a brightness that was brighter than a full moon. Some unburned meteorite fragments were found in Chengtou Village, Pujiang County, Jinhua.
The crater, about 8 centimeters in diameter, was later found on the concrete floor at the gate of a farmer's house in the village.

Sergei Krikalev, a former cosmonaut who is now director of crewed space flight programs at Russia's space corporation, said Thursday's leak from the Soyuz MS-22 could affect the capsule's overall coolant system but that there was "no threat for the crew" of the space station.
The leak had prompted a pair of cosmonauts to abort a planned spacewalk earlier in the day. It also raises concerns as to whether the capsule will be able to safely return to Earth next spring as planned with two cosmonauts and a Nasa astronaut, or if an emergency replacement vehicle will have to be sent up.
Comment: Note that, if this is indeed what they suspect, this follows an incident in June whereby a micrometeoroid hit the recently launched James Webb Telescope: First micrometeoroid impact hits James Webb Space Telescope just months into flight
