ESAHerschel: Exactly 4 years ago today @ESAHerschel's first instrument - SPIRE - was switched on after launch. SPIRE is the last instrument operating now
最初に点いて、最後に消える

ESAHerschel: The post-cryogen tests are going well and @ESAHerschel is moving gradually away from the Earth-Moon system in its disposal orbit.
ESAHerschel: There is still one, final burn of the thrusters to come. This will drain them of all remaining fuel after all tests are completed.

ESAHerschel: After that, who knows? Maybe Herschel will be recovered one day & end up as an exhibit in an Air & Space Museum.
ESAHerschel: Herschel is now 1.0242AU from the Sun and almost 1.9 million kilometres from Earth, moving south in the constellation of Libra.
回収する気があるならもっとこっちに持って来ようよESA。でもL2点よりは近いのか？
