Kinetic Impactor: A way to save Earth

May 15
The principle of the kinetic impactor mitigation method is that the NEO 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 10km/s or more. The mass and velocity of the impactor (the momentum) are transferred to the NEO, causing a change in velocity and therefore making it deviate from its course slightly. The NEOShield team

Comets PanSTARRS C/2012 K1 and 209P/LINEAR will be visible on May

May 14
May is an electrifying month for sky-watchers and space enthusiasts! Two comets will be visible in the next days: comets PanSTARRS C/2012 K1 and 209P/LINEAR. The best news is that both will be visible also just with binoculars or small telescope and according to NASA both comets will be easy to find. The video below has been realized by NASA's Jet Propulsion Laboratory in Pasadena and shows how to locate the two comets.  (Credit: NASA)

Rosetta’s first glance to comet 67P Churyumov-Gerasimenko

May 09
After a 10-years-long travel through the Solar system Rosetta will finally arrive at the comet 67P/Churyumov-Gerasimenko the next August. «Finally seeing our target after a 10 year journey through space is an incredible feeling» said Holger Sierks, OSIRIS Principal Investigator from the Max Planck Institute for Solar System Research in Germany. OSIRIS is one of the 11 Rosetta’s science instruments essential to analyze the comet’s geology, gravity, mass, shape, and internal structure. OSIRIS and two

A possible meteor shower in may

(Image: NASA Science) «We have no idea what the comet was doing in the 1800s. There could be a great meteor shower or a complete dud» affirmed Dr. Bill Cooke, head of NASA's Meteroid Environment Office. The May Camelopardalis shower is caused by dust from periodic comet 209P/LINEAR. It would be the first time after more than 200 years. As Dr. Cooke said «Some forecasters have predicted more than 200 meteors per hour», so it
