The reconstruction of what a massive asteroid caused on Earth

Apr 11

Scientists reconstructed the consequences that 3.26 billion years ago a massive asteroid had on Earth. It was almost 37 km wide and hit an area vast like South Africa. The energy arose from its impact caused a half-hour-long earthquake, boiled the oceans and colored the sky of deep red.

This 2001 QC34 earth encounter is a relatively shallow close approach, because of the geometrical relationship and movements of the sun – asteroid – earth phase


One step closer to Mars: sending humans to an asteroid

Apr 08

Another challenging mission planned by NASA: sending humans to an asteroid. Just after the announcement of the ambitious project of capturing an asteroid and redirect it to an orbit around the Moon, the space agency communicated the intention to send astronauts to an asteroid during a forum which took place on March 26, 2014.

Asteroid 2007 VK184 crossed out as potential menace for the planet

Apr 07

Since asteroid 2007 VK184 was discovered in November 2007 by the NASA-funded Catalina Sky Survey (CSS) at the University of Arizona has been added in the NASA´s asteroid impact hazard list. It was considered a real threat for a number of years with an estimated size of 130 meters and a rating of 1 on the 10-point Torino Impact Hazard Scale.
