The European Space Agency has a successful launching of an Ariane 5 rocket bearing the XMM Telescope. This telescope, named the X-Ray Multi Mirror, could be as important to astronomy as the Hubble Space Telescope (currently inoperational, with the Space Shuttle repair mission delayed yet again). Besides the X-Ray receiver, there are optical instruments on board as well. I do take issue with the following line: with its sensitive cameras it will see infinitely more than any previous X-ray satellite. “Infinite” is a mighty big word to be throwing around, especially in the space sciences.
