The Philae robot sends signals from comets to Earth

The exploration robot Philae has reestablished contact with Rosetta and sent data to the earth after two days landing on a comet surface.

"Philae has now reestablished stable communication - scientific and scientific data is transmitted from the surface of comet 67P / Churyumov-Gerasimenko" , BBC quoted the European Space Agency's (ESA) announcement on Twitter last yesterday.

After a bounce when landing, scientists could not determine the exact location of the robot on the comet. However, according to the photos sent, it is under a cliff.

The news ended ESA's stressful wait for the past few days, fearing that Philae's battery is about to run out. Limited sunlight has affected its solar panels.

Philae landed on the comet on November 12 after separating from the Rosetta spacecraft. This is the first time the world space science has achieved this achievement. However, engineers believe that with the current position, Philae only has enough energy to maintain operations today.

The biggest concern now is whether Philae will get the specimen from the comet surface with its drill. The exhausting energy source has led the control team to deploy drilling yesterday.

The torque of this tool poses a risk of robot instability. However, according to the latest communication, Philae seems to have no major problems in drilling and drilling tools are transmitting scientific data about the earth.

Engineers are trying to improve the energy state for Philae by passing commands to change its body configuration. Its main body is being raised and rotated 35 degrees to maximize the ability to receive sunlight for the panels.

Even if robots stop contacting this weekend, the researchers say they are still very pleased with the amount of data collected to learn more about the origins of the Solar System. About 80% of the basic goal was achieved before Philae performed the task of drilling the surface of the comet.
