about 1k days of terror, all of these deployments going on but really, it s all gone off without a hitch, so we couldn t ask for better. what s next, then? there are so many parts that could have gone wrong, but let s look forward to what the next milestone is. absolutely. so starting in a few days, we re going to be aligning the mirrors, so it can take clear images of space. and so, the mirror s made of 18 individual segments that can be moved individually so they will be going on for several months and we also need to cool down the telescope to very cool temperatures, 230 celsius, and we ll be able to then turn on all the instruments, make sure they work to finally start doing science. has it actually arrived at its final destination, known as l2, hasn t it? that s right not quite yet. we think around 23 january, it will be in l2, as he said. canada is one of three partners taking part in this fantastic project what is canada s contribution?
