re: Some recent EML-1 Comments
SEL2 isn't actually in Earth's shadow.
It could be kept away from it all the time.
If a platform orbits SEL2 (like SOHO orbits around SEL1-Halo orbit), then it will never be in Earth's shadow.
Besides, the Earth is about as large as the Moon is from here, from SEL2.
And solar eclipses only involve a 120 km wide shadow.
I wonder about servicing a telescope in ESL2... If it's through an ion engine, it's going to take a very long time to return it closer to Earth (or L1). But then, it could go on achieving science, even if not in SEL2 anymore. However, if the engine runs continuously, this might not be the case.
