Comet probe Philae has started drilling into the surface of the comet which it landed on this Wednesday.
But there may not be enough power left in the craft's depleting batteries to obtain scientific data from the samples it collects.
Philae is believed to be tilted to one side in the shadow of a crater wall and is not getting enough light to recharge its batteries using electricity generated by its solar panels.
With less than 24 hours before the craft's primary battery power runs out, scientists are actively considering taking a last-ditch gamble and "hopping" the lander to a sunnier spot. Read: Scientists debating whether to 'hop' Philae to new spot
Just two years ago a group of Cambridge engineers created the Raspberry Pi - their aim was to make a very cheap computer that youngsters could programme - and learn how it works.
They've since sold almost 4 million of them... And now they've brought out a new version -"the A plus." At just under 20 pounds it's the cheapest computer they've produced.

Scientists have confirmed that Philae, which was built with the help of scientists from our region, is on the surface of a comet more than 300 million miles from earth.
Members of the European Space Agency said the Rosetta probe was operating well, but they don't know for how long.

Rosetta’s lander Philae is safely on the surface of Comet 67P/Churyumov-Gerasimenko, as these first images confirm. One of the lander’s three feet can be seen in the foreground.
Hello! An update on life on #67P - Yesterday was exhausting! I actually performed 3 landings,15:33, 17:26 & 17:33 UTC. Stay tuned for more
The European Space Agency has thanked its Twitter followers for their enthusiasm and support during today's Rosetta space mission.
Posting on it's official Twitter account the ESA said "You make 24-hr-long-days worthwhile!"
Scientists at the European Space Agency say they have concerns over the fate of the Philae Lander.
As the anchors did not fire they cannot say "with 100% certainty that we are on the comet and are staying there." They are observing the movement of the lander to confirm it is stationary on the comet rather than "still in movement."
I’m on the surface but my harpoons did not fire. My team is hard at work now trying to determine why. #CometLanding
Earlier reports had said the harpoon anchors had fired.
More analysis of @philae2014 telemetry indicates harpoons did not fire as 1st thought. Lander in gr8 shape. Team looking at refire options
The Philae Lander is almost ready to start its landing on the comet.
The spider-like craft separated from its orbiting Rosetta mothership at 9.05am, to touch down on comet 67P/Churyumov-Gerasimenko, a 2.5 mile-wide rugged lump of ice and dust hurtling through space at around 40,000 mph.
The two space craft which journeyed to a comet chronicled their journey with an intimate back and forth like old friends on a road trip.Read the full story ›
