Space agency releases 1st picture of Philae lander from comet

world Updated: Nov 14, 2014 07:16 IST

The European Space Agency on Thurday published the first image taken from the surface of a comet, and said that its Philae lander is still "stable" despite a failure to latch on properly to the rocky terrain.

The lander scored a historic first on Wednesday, when it touched down on comet 67P/Churyumov-Gerasimenko after a decade-long journey through space on its mother ship Rosetta.

Scientists' jubilation was slightly dampened because the harpoons which were meant to anchor the lander to the surface failed to deploy, causing it to bounce twice before it came to rest on the comet's body, or nucleus.

The combination photo of different images taken with the CIVA camera system released by the European Space Agency ESA on Thursday Nov. 13, 2014 shows Rosetta’s lander Philae as it is safely on the surface of Comet 67P/Churyumov-Gerasimenko, as these first CIVA images confirm. One of the lander’s three feet can be seen in the foreground. Philae became the first spacecraft to land on a comet when it touched down Wednesday on the comet, 67P/Churyumov-Gerasimenko. (AP Photo)

"Philae is stable, sitting on the nucleus and is producing data," Gerhard Schwehm, a scientist on the Rosetta mission, told The Associated Press. "The lander is very healthy." The photos sent back to Earth show a rocky surface, with one of the lander's three feet in the corner of the frame.

Scientists are still analysing what effect the two bounces had on the spacecraft and plan to release further details at a news briefing at 2pm (1830 IST).

Schwehm said it may still be possible to fire the harpoons, but that this would be done only if it doesn't imperil the lander. A key question is whether Philae's drill can be used to extract samples from beneath the surface without pushing the lander into space.

Gravity on the comet is 1/100,000th that of Earth, meaning the washing machine-sized lander weighs just 1 gram (0.04 ounces) there. Philae and Rosetta will use 21 instruments to analyze the comet over the coming months. Scientists hope the 1.3 billion euro project ($1.62 billion) will help them better understand comets and other celestial objects, as well as possibly answer questions about the origins of life on Earth.
