3-ring Venn Diagram
- launched in 1999
- launched in 2000
- will be launched in 2008
- 1.5 million miles above Earth
- superior apertures
- consists of four telescopes
- detects broader range of x-ray wavelengths
- collecting areas 3 square meters which will detect x-ray sources
100x fainter
- more quantitative data on abundance, velocity, temperature
- data collected in hours instead days
- focus on smaller areas which will exclude picking up signals from
external medium of hot gas
- superior ability to discriminate amongst different x-rays
wavelengths
- 45 feet long
- flies more than 1/3 of the way to the moon
- exquisitely shaped for pairs of mirrors
- 2,000 watts electrical power generated by solar power same power
as hair dryer
- deployment of observatory commanded by woman
- images will be 25x sharper than previous x-ray telescopes
- focusing power equivalent to the ability to read a newspaper a
half a
mile away
- detailed studies of blackholes, supernovas, dark matter, origin,
evolution, and destiny of the universe
- X-ray telescopes are one way to observe extremely hot matter with
temperature of millions of degrees
- observatory must be placed high above Earth's surface because
Earth's
atmosphere absorbs X-rays
- 32 channel array of microcalorimeters
- 10X HIGHER SPECTRAL resolution power in the Fe-K region
- incorporates a three stage cooling system capable of operating the
array at 60 mK for about two years
- designed to study the universe in x-rays
- a high resolution X-ray spectrometer based on a microcalorimeter
array, four CCD X-ray cameras, and a hard X-ray telescope
- uses high resolution camera and CCD imaging spectrometer
- detects and images X-ray sources billions of light years away
