It is very unlikely right now. We have 1.5 hours [of sunlight] at less than 1 watt, and 20 minutes of 3 or 4 watts. The lander needs 5 watts to boot….In order to charge the secondary battery, we have to heat it to 0 degrees Celsius. We need about 50-60 watt-hours a day in order to reach 0 degrees and still have daylight left to charge the battery. So it doesn’t look that great. What we could hope for is if we are closer to perihelion, near 1 AU, maybe we could have enough energy on our one solar panel, maybe every once in a. Having [a communication] link requires additional power again.
Q: Why no nuclear battery?
A: RTGs have many issues. Plutonium has many safety and political implications. Europe doesn't have the technology to produce RTG, mostly due political reasons.
