Philae wake-up

The European space probe Philae woke up earlier this month after nearly seven months in hibernation as it hurtled towards the Sun on the back of a comet. The tiny robot lab may be ready to resume science work, adding a fresh chapter to its extraordinary voyage, excited officials said. The mission seeks to unlock the long-held secrets of comets -- primordial clusters of ice and dust that scientists believe may reveal how the Solar System was formed.VIDEOGRAPHIC
