The European Space Agency (ESA) released a photograph of the washing machine-sized robot lab on the comet's rough surface, one leg thrust into the air.
The image, captured with the Rosetta orbiter's OSIRIS narrow-angle camera on Friday last week, were downloaded two days later -- just weeks before the official end of the ground-breaking science mission to unravel the mysteries of life on Earth.
The 1.3-billion-euro (USD 1.4-billion) mission, saw Rosetta launched into space in March 2004, with Philae riding piggyback.
The pair travelled some 6.5 billion kilometres to enter comet 67P/Churyumov-Gerasimenko's orbit in August 2014.

Three months later, Rosetta sent the 100-kilogramme probe down to the comet surface, starting a deep-space saga closely followed around the world via cartoon recreations of the pioneering pair.
Until now, nobody knew exactly where.
"This remarkable discovery comes at the end of a long, painstaking search," said Rosetta mission manager Patrick Martin.
"We were beginning to think that Philae would remain lost forever. It is incredible that we have captured this at the final hour."
Philae's nail-biting exploits earned it a loyal Twitter following.
It managed to send home data from 60 hours of experiments, before its batteries failed and it entered standby mode.
