It's Alive! Comet Lander Philae Phones Home After Months of Silence
The European Space Agency's Philae comet lander is seen by the Rosetta spacecraft in this image captured on Nov. 12, 2014 as Philae headed for its landing on Comet 67P/Churyumov-Gerasimenko. The probe went silent 60 hours later and reawakened on June 13, 2015.

     A European probe that made a bouncy landing on a comet last year, and then slipped into a silent hibernation, is alive again and phoning home.

The European Space Agency's Philae comet lander, which dropped onto Comet 67P/Churyumov-Gerasimenko from the Rosetta spacecraft last November, beamed an 85-second wake-up message to Earth via Rosetta yesterday (June 13), ESA officials announced today. It was the first signal from Philae in seven months since the probe fell silent on Nov. 15 after its historic comet landing. . . .

Are Organic Molecules Found on Philae Comet Ingredients for Life?

Philae Lander 'Sniffed' Organic Molecules on Comet's Surface

     BERLIN — The European Space Agency's Philae comet lander "sniffed" organic molecules before its primary battery ran out and it shut down, German scientists said. They said it was not yet clear whether the molecules included the complex compounds that make up proteins. One of the key aims of the mission is to discover whether carbon-based compounds, the basis of life as we know it, were brought to early Earth by comets.

Philae landed on Comet 67P/Churyumov–Gerasimenko after a 10-year journey through space aboard the Rosetta spacecraft, on a mission to unlock details about how planets and perhaps even how life evolved. It wrapped up a 57-hour marathon of scientific experiments on the comet's surface on Saturday as its batteries ran out. Philae's COSAC gas-analyzing instrument was able to sniff the comet's ultra-thin atmosphere and detect the first organic molecules after landing, the DLR German Aerospace Center said. The lander also drilled into the comet's surface, although it is still unclear whether Philae managed to deliver a sample to COSAC for analysis. . . .

Comet Probe Finds Elements of Life

    The Rosetta spacecraft has discovered all the elements of life in the gases jetting from a comet as it approaches the Sun.

The ingredients that make up amino acids, life’s building blocks, are all contained in the tail of the comet 67P/Churyumov-Gerasimenko (67P/C-G). Among them are methane, methanol, CO2, ammonia and water. All proteins are made of amino acids.

If Rosetta’s lander, Philae, discovers complete amino acids when it reaches the comet’s surface in November, it would support the hypothesis that life on Earth was seeded by comets with complex organic molecules as well as water. . . .
