Solar panels power production: 4 out of 6 are producing.

Onboard computers (main & redundant)

Panel 6 (roof)

Internal lander temperature at sunrise is already -35°C (minimum operating temperature is -45°C)

Sunrise Not enough power Sunset

Typical comet day

Needed for drill and ovens (analysis)

Save data to permanent memory before switchoff, waiting for next available upload slot.

Enough power

Did not reach the ground

Did not collect samples

Possible Philae location.Closer flybies needed for confirmation. Rosetta currently at 250 km from comet due to dusty environment.Closest approach in past months was 8 km.

Planned landing site: northern emisphere, 9 hours of light out of 12.4.

Actual landing site: southern emisphere during winter, hence mostly in shadow until june 2015.

Energy increment due to 22° lander rotation on 14/nov/2014: +20%

Philae wakes up (jun 13): +320%

Perihelion (shortest distance from Sun): +480%

Solstice (longest daytime): +210%

Equinox (day starts being longer than night): +50%
