Philae batteries are exhausted. He had to take a sample! – Polish Radio

Connection indicated that the lander, which is located at the distance of 511 million km comet 67P / Churyumov-Gerasimenko, still had energy.

Data transfer started on Friday at 23:29 Polish time.

The ESA still do not know the exact location of the lander, but the data received from him.

WHAT HAPPENS WITH PHILAE? REPORT PRESS CONFERENCE after Friday & gt; & gt; & gt;

It lasted a race against time. Agency wanted to do as much research comet’s surface before the original equipment batteries are exhausted. Philae is located in a shady spot and it is highly doubtful to obtain power from the solar battery back-up.

Scientists ESA launched all research instruments lander. They worked apxs, MUPUS, drill and SD2, which provided the sample to the analyzer COSAC and Ptolemy.

After midnight the night from Friday to Saturday, the ESA has confirmed on his Facebook account that has managed to make drilling and sample. This is the first in the history of the sample, which was collected from a comet! Experts from ESA ground teams analyze data that have been released from the lander to make sure that the drilling was complete.

They were made:

– research with the help of Ptolemy instrument designed for the analysis of elements light on the surface of a comet.

– At least 3 photos from a camera to a new position Rolis lander

– downloaded the data from the experiment CONSERT “screener” comet

Exciting night in the Mission Control Center in Darmstadt and the Lander Control Centre in Cologne, Germany.

We already know that studies have been done with the help of Ptolemy instrument, designed for the analysis of light elements on the surface of a comet. At least three images made Rolis camera in the new position of the lander. Also downloaded the data from the experiment CONSERT “screener” comet.

The batteries have run out of Philae on Saturday. May be able to wake the lander when lighting conditions change on a comet, and she approaches the sun.

Rosetta probe, which revolves around a comet, still performs his research without any interference, so the Rosetta mission continues.

About one in the morning – an ongoing links with the Philae – ESA said in the blog that the battery level dropped to near 21.5 V. Below this level, the battery does not provide power supply unit.

About 1:30 Polish time Philae instruments excluded because of a lack of energy. Since then, the lander is in sleep mode and sends only basic data.

ESA managed to download all data collected during the first drilling (First Sequence Science).

On Friday around midnight Philae rotated about 35 degrees to a more “expose” him at the sun. Maybe even in the near future to regain connectivity. ESA does not lose hope.
