XMM-Newton scores 1000 top-class science results (http://www.physorg.com/news10218.html)


XMM-Newton, ESA's X-ray observatory, continues its quest for the unknown. This month, after five years of operations, the mission saw the publication of its 1000th scientific paper, corresponding to an equivalent number of results, in top-class scientific journals. This is not the only record-breaking figure for this X-ray 'hunter' mission.

Scientific results based on XMM-Newton data are now being published at a steady rate of almost 300 papers per year, comparable to the famous Hubble Space Telescope.

Unique in-flight upgrade for XMM ground systems

....Last year, ESA's Science Programme Committee extended operation of ESA's hugely valuable X-ray observation mission, XMM-Newton, for four years, until 31 March 2010. The decision was easy given the incredible science results that XMM has provided since launch in 1999, with over 1,000 scientific papers having been published based on XMM data.

I can think of several NASA missions that have redone their control center software while operational, including Hubble.

very true, maybe this is the first Xray mission to be upgraded in this way

Astronomers have witnessed a never-seen-before event in observations by ESA’s XMM-Newton spacecraft - a collision between a pulsar and a ring of gas around a neighbouring star.
The rare passage, which took the pulsar plunging into and through this ring, illuminated the sky in gamma- and X-rays.

It has revealed a remarkable new insight into the origin and content of ‘pulsar winds’, which has been a long-standing mystery. The scientists described the event as a natural but ‘scaled-up’ version of the well-known Deep Impact satellite collision with Comet Tempel 1.
Their final analysis is based on a new observation from XMM-Newton and a multitude of archived data which will lead to a better understanding of what drives well-known ‘pulsar nebulae’, such as the colourful Crab and Vela pulsars.
