Mission Length:? Why is the mission Length so Short? It is my understanding that the telescope is still operating. Did the initial 4 days have a cooled detector for calibration that is no longer present? —Preceding unsigned comment added by 220.127.116.11 (talk) 17:10, 16 September 2008 (UTC)
That length refers to the shuttle mission that launched the telescope. --Etacar11 03:28, 17 September 2008 (UTC)
The article says Chandra has a resolution 1000 times better than the earliest x-ray telescope. However, according to NASA at , it has a resolution 8 times better. This might need to be changed. —The preceding unsigned comment was added by 18.104.22.168 (talk • contribs) 01:59, March 10, 2007 (UTC)
The NASA ref says "It has eight-times greater resolution and is able to detect sources more than 20-times fainter than any previous X-ray telescope." rather than the earliest so there's no conflict. Just need to add which was the earliest and which was the best prior to 1999. - Rod57 (talk) 14:15, 17 May 2017 (UTC)
werent' the detectors damaged during spacecraft checkout?--Patbahn (talk) 15:48, 18 February 2011 (UTC)
Proposed automatic updating of orbital elements
I've proposed that this article be included in a trial involving using a bot to update orbital elements automatically on a fortnightly basis. I've started a discussion at WikiProject Spaceflight regarding this article and nine others, and would welcome some input from the users involved in maintaining the pages in question. --W.D.Graham 20:59, 24 July 2013 (UTC)
> Chandra is sensitive to X-ray sources 100 times fainter than any previous X-ray telescope, enabled by the high angular resolution of its mirrors.
Sounds intersting. What means the "angular resolution of mirrors?" I wouldn't mind a little technical talk. 22.214.171.124 (talk) 15:06, 21 June 2015 (UTC)
It means how small an angular size an object can have and be resolved by the telescope's optics. Here's a quickie about angular size: From Earth, the Moon has a certain angular size, about 1/2 of one degree. The planet Jupiter, from Earth, has a much smaller angular size. In terms of kilometers (or miles, or whatever), Jupiter has a diameter very much larger than does the Moon. If they were side-by-side at the same distance, Jupiter would look enormously bigger than the Moon. But since the Moon is much closer than Jupiter it can have a larger angular size.
The angular resolution of a telescope has to do with whether it can resolve Jupiter as a recognizable disc or just a fuzzy blur. The larger the diameter of the telescope's objective mirror, and the more precisely its surface is shaped like a paraboloid, the better its angular resolution. Put another way, it's like whether or not you can read the words on a billboard from some distance.
