DARMSTADT, Germany — Europe’s comet-bound Philae probe released from its Rosetta orbiter mothership Wednesday, and the two spacecraft snapped farewell photos as they went separate ways for the first time after a ten-year journey from Earth to comet 67P/Churyumov-Gerasimenko.

The imagery showed each spacecraft backdropped by the velvety void of space.

The images were taken minutes after ground controllers confirmed the oven-sized spacecraft flew away from Rosetta at 0903 GMT (10:03 a.m. EST) flew away from Rosetta to make the first landing attempt on a comet.

“We took an image 60 seconds after release, and it worked perfectly well,” said Jean-Pierre Bibring, Philae’s lead scientist and principal investigator for the lander’s CIVA infrared and visible camera suite.

“We won’t see the orbiter any more,” Bibring said. “We said bye-bye to him.”

The imaging system is made of seven micro-cameras and was developed by the Institut d’Astrophysique Spatiale in Paris.

Once Philae lands on the comet, the probe’s cameras will take a series of photos for a panorama and 3D stereoscopic imagery.

Rosetta’s main camera system, led by the Max Planck Institute for Solar System Research, also took images of Philae soon after its deployment.

A zoomed-in photo from Rosetta’s OSIRIS camera showed the lander’s three legs, camera and instrument booms extended as planned.

Confirmation of Philae’s touchdown is expected around 1600 GMT (11 a.m. EST) Wednesday.
