Comet Lander's Unexpected Final Position

BERLIN (AP) — The European Space Agency says its comet lander appears to have come to rest in the shadow of a cliff, posing a potential problem for its solar panels.

Potential Power Issues for Philae

Mission scientist Jean-Pierre Bibring says ground controllers will see whether it’s possible to adjust the lander to make sure its solar panels can catch the sun and charge the batteries.

Landing Stability and Lander Condition

Bibring said Thursday that the lander, called Philae, also appears to be standing on just two of its three feet.

He stressed that — apart from the unplanned alignment — the lander’s scientific instruments are operating normally.

Historic First for Space Exploration

The landing Wednesday was the first time a spacecraft has ever landed on a comet.

Key Takeaways

  • The Philae lander ended up in shadow next to a cliff on Comet 67P, limiting sunlight on its solar panels.
  • Despite the awkward positioning on two legs and lack of full anchoring, Philae’s instruments functioned initially.
  • Ground controllers considered adjusting its orientation to catch more sunlight and extend mission life.
  • Philae’s primary battery power was limited, making solar recharge critical for longer operations.

Frequently Asked Questions

What problem did Philae face after landing?
It landed in the shadow of a cliff, limiting solar panel exposure and reducing its ability to recharge its batteries.
Is Philae stable and operational?
Despite landing at an awkward angle and only on two of its three legs, its scientific instruments were operating normally at first.
Can engineers adjust Philae to improve solar exposure?
Mission scientists said ground controllers planned to evaluate whether it’s possible to adjust the lander’s orientation to enhance sunlight on the panels.
