Answers

  1. It's false. Messenger is the first to orbit Mercury, but Mariner 10 made several passes in the 1970s. It took more than 7,000 photos of Mercury, Venus, the Earth and the Moon.
  2. Olympus Mons - Latin for Mount Olympus - is a volcano about three times the size of Everest, making it the largest known volcano in the solar system.
  3. Voyager 6 evolves into V'Ger, a destructive alien cloud in Star Trek: The Motion Picture. Sorry about the spoiler, folks. Option one is the plot of Alien, and option three is the plot of Star Trek IV: The Voyage Home.
  4. It's "snow globe" - images from Nasa's probe Deep Impact shows the comet Tempel 1 is surrounded by fluffy ice particles. On the same mission, it also photographed the comet Hartley 2, described as a "space peanut". Last week, another probe - Stardust - photographed craters on Tempel 1.
  5. It's Phoenix, which landed in 2008 but thought to have broken apart in the Red Planet's winter. Vikings 1 and 2 were the first US probes to land on Mars in 1976 - several years after the USSR's failed probes Mars 2 and 3. Beagle 2 was the British lander lost in 2003. And Phobos 1 and 2 were Russia's failed probes in the 1980s.
  6. It's number 4. Beagle 2 successfully ejected from the European Space Agency's Mars Express on 19 Dec 2003, and was expected to land on Christmas Day. But nothing more was heard from it, and the mission was presumed lost.
  7. Akatsuki translates as "dawn". It had been due to conduct joint observations with the European Space Agency's Venus Express craft, which arrived in 2006.
