For the first time in history, a spacecraft has landed on a comet! We are talking about the historic feat of Rosetta and its lander Philae. Here's a concise presentation about their historic journey.

2. Hi, I’m Rosetta. I’m a robotic spacecraft carefully built and launched by the
European Space Agency. I got my name from the famous Rosetta stone
whose carved inscription unravelled the history of Egypt.
Dimension:
2.8 x 2.1 x 2.0 m with two 14 metre long solar panels

3. This is Philae, my lander. It was named after
the island in the Nile River where an obelisk
with bilingual inscription was found. The
inscription helped historians decipher the
characters on Rosetta stone.

4. Yes, we were named after two greatest discoveries
in the world because we are meant to uncover
something grand. During our 12-year journey across
the solar system, we have a super cooool mission:
To study in detail the comet called 67P/Churyumov–
Gerasimenko.

5. Our adventure began in March 2004
on an Ariane 5 rocket in French
Guiana. Then we started chasing our
target comet. We crossed the asteroid
belt and travelled into deep space,
more than five times Earth’s distance
from the Sun. Whew, that far.

6. But on August 6, 2014, we finally
arrived at the comet and just last
November 12, 2014, Philae
dramatically landed on the comet’s icy
surface. What a phenomenal feat!
People celebrated, people hugged,
people partied. We were even trending
on Twitter. #cometlanding

7. We are supposed to collect as much information as we can about one
of the oldest objects in our solar system. Unfortunately, Philae’s
battery ran down a day after it landed on the comet. Now it’s taking a
long nap.
But hey, I’m still alive and kicking. I will continue to orbit the comet as
it heads towards the inner solar system. I will witness how this icy
comet will produce its coma and tail as it gets close to the sun. Up
close and personal. Cool!

8. I will update you with my discoveries and experience through the
radio link. And Twitter, of course. Follow us and let’s all prove science
rocks!
And hey, do wish me safety and success as I
continue to explore space until December 2015.
