L’Italia e l’esplorazione dello spazio.
L’Italia, insieme ad altri
paesi europei, ha contribuito alla realizzazione della missione spaziale
Rosetta.
Vedi anche l'articolo di settembre 2015 che descrive in dettaglio la missione nello spazio di Rosetta.
Philae's final resting place has been found
ESA's comet lander missed its mark
two years ago. Last Monday, its parent craft Rosetta found the probe finally.
After not knowing the exact location of the Philae lander
for almost two years, the cameras on the European Space Agency’s Rosetta
orbiter picked up images on Friday of Philae tucked into a crack on Comet
67-P/Churyumov-Gerasimenko.
Philae was attached to Rosetta during its 10-year journey
through space to catch up to the comet and was released to touch down in
November 2014, making it the first spacecraft to land on a comet. It sent data
to Earth for three days before its battery died, causing Philae to go into
hibernation. When the comet came closer to the sun, though, it helped charge it
enough to communicate with Rosetta briefly in 2015.
Thanks to radio signals between Rosetta and Philae, the
general area of where Philae landed was known, but it had bounced after its
initial touchdown and the exact location couldn’t be found until now.
Rosetta was 1.7 miles from the comet’s surface when it
captured the images that show Philae’s body and two of its three legs.
Rosetta will join Philae on the surface of Comet 67P, as it
is scheduled to crash into the comet on September 30 to investigate the comet
from close up and complete its mission.
The
data recovered from Philae has already immensely helped scientists to
understand the nature of comets and the role they play in universe.
