After a grueling number of hours and a 10-year journey, the Philae lander has successfully arrived on its target. The probe will relay information back to Earth about the ancient comet 67P and hopefully unravel secrets about our universe and Earth’s creation.

The spacecraft Rosetta was launched almost 10 years ago from the European Space Agency’s spaceport in French Guiana, according to ABC News. The spacecraft's mission was to follow comet 67P and orbit around the space rock.

The spacecraft was scheduled to land at around 8:30 a.m. Eastern Time. Sometime after 11 a.m, it was expected to be clear if the spacecraft landed and is working from over 300 million miles away.

Both Philae and the ESA confirmed via Twitter that the landing proved to be a success.

Philae tweeted the news in various languages, announcing to the world its new home address.

However, it was not a simple process.

According to the Wall Street Journal, scientists at the ESA’s headquarters in Germany were worried the probe’s faulty thrusters may endanger the landing.

“The cold gas thruster on top of the lander does not appear to be working, so we will have to rely fully on the harpoons at touchdown,” Stephan Ulamec, the Philae lander manager, said.

Tthe landing happened without many problems, reports CNN. Philae’s harpoons fired properly and screws on each of the lander’s feet attached to the comet.

The ESA confirmed via Twitter:

The washing machine-sized probe will use its various cameras and equipment to analyze the comet. The probe is outfitted with drills and ovens to retrieve and test material from the comet, which some scientists believe may have contributed to the creation of life on Earth.

Rosetta will continue to orbit around 67P for a year as the comet nears the Sun, when it will release “hundreds of kilograms of material every second.”
