The official Chinese news agency Xinhua reported yesterday that the country had postponed the launch of its first space telescope by two years, until 2012, due to cost problems. The Hard X-ray Modulation Telescope (HXMT) will be the country's first observatory, originally scheduled for launch in 2010, as part of the nation's ambitious space program, which already saw the launch of the first “taikonauts†in low-Earth orbit in 2003. The cost of the observatory is estimated to be of about one billion yuan ($146.4 million), which is not much by NASA standards, for example.The instrument is the first of its kind, designed specifically for discovering and analyzing black holes. Rather than sporting a set of lenses or mirrors to aid it in observing the Universe, the HXMT will use three or four single telescopes, each of them outfitted with hard X-ray detectors. It is essentially based on the direct demodulation (DD) method and the well-developed NaI(Ti)/CsI(Na) phoswich detect!
ing techniques. NaI(Ti) stand for sodium iodide doped with thalium. The collimated hard X-ray instrument will work with particles in the 20-to-200-keV energy range.It will scan the skies looking for X-ray sources, and the team behind the project, supported by the Ministry of Scien...
