Messenger to Mercury

Tonight at 12.45am [GMT] Nasa’s Messenger spacecraft will begin a 15 minute engine burn timed to take it into orbit around Mercury – the first spacecraft to do so.  (All images credit: NASA/Johns Hopkins University Applied Physics Laboratory/Carnegie Institution of Washington) Launched on 3 August 2004, Messenger’s taken a circuitous route to the innermost planet. It’s second, and final, look at the Earth was in August 2005. Twice past Venus, the second time in June 2007 Before not one, not two fly-bys, but …
