NASA's Northrop Grumman-built Aura satellite was launched by Boeing Delta II on 15 July, joining the Aqua and Terra Earth observing system (EOS) spacecraft. Aura is expected to begin measuring atmospheric gases from its 705km (440 mile) -high Sun-synchronous orbit within three months. Launch of NASA's Mercury probe, Messenger, has been scheduled for 2 August. The radar-imaging craft will not enter orbit until March 2011.
