Mini Hubble天文一号观测卫星 - 業餘天文的太空望遠鏡

可能十多年後很多人都可以擁有自己的太空望遠鏡!

Just found the above info. A mini Hubble telescope designed for amateur astronomers. It is a very interesting project!

According to the very brief info, it is a 300mm aperture telescope which amateurs can hire for remote observations. The theoretical resolution of a 300mm telescope is ~0.4". This is roughly equivalent to the seeing at the best sites on earth (eg Mauna Kea). So with such a telescope in orbit, you should be able to take images with resolution close to the best telescopes on earth.

For comparison, Hubble has a 2.4m aperture which has a resolution of ~0.05".

Originally planned for launching this June, but it has just been suspended. Hope it will come to live soon. It seems that it has encountered some technical difficulties. Not sure what it may be.

快舟一号甲 (KZ-1A) just launched this Monday (9-Jan-2017) has a cost of ~100,000RMB per kg. The above mini-hubble scope weights 35kg. So the launching cost should be about 3.5m RMB. Not really that expensive for a commercial project. KZ-11 is planned for later this year which will bring the cost down further to below U$10k per kg. The planned launch of KZ-21 is 2025, with expected cost of ~U$1k per kg! By that time, launching your own space telescope may become a reality! Sit tight!!!

Yes, perhaps even more interesting than a large telescope project on earth. :wink:
