Itokawa: a rare collision of two different objects
Itokawa is partly compact with relatively high specific density, while the other is rather porous, which means low specific density. These are the findings of an international team of scientists, including researchers from the Max Planck Institute for Solar System Research in Göttingen. This is the first time that scientists managed to catch a glimpse into the inner life of an asteroid. (Image: ESO/JAXA) Itokawa is a peanut-shaped asteroid of about 600 m longest dimension.
On the importance of prevention

The video shows the places where NEAs impacted and it has been released in occasion of the Earth Day on April 22, 2014. Luckily, many asteroids exploded in the atmosphere without injuring people. This clip displays how intense the energy generated by asteroids was and inform us on the potential menace they represented for
Another objected exploded in Russian skies
Just one year since a meteorite blasted above Chelyabinsk, a suspected meteorite explosion has been filmed by citizens of Murmansk in Russia on April 19, 2014. Luckily, nobody has been injured. Different hypothesis on the object has been done: it could be a meteorite or just space debris re-entering the atmosphere. (Image: @RussiaToday) Chelyabinsk celebrated the birthday of the “17-meter celestial boy” with a festival. On that occasion scientific conferences took place and a memorial
Go-Ahead for OSIRIS-REx Mission
Several experts from NASA and external organization worked at the mission system design. On April 2, the Mission Critical Design Review (CDR) for NASA’s Origins Spectral Interpretation Resource Identification Security Regolith Explorer (OSIRIS-REx) communicated the news. OSIRIS-REx will be sent into space in the fall of 2016. It will reach the asteroid Bennu and then return a sample of it to Earth in 2023 for scientists to study.
