Spacecraft clocked fastest launch speed,recorded first video of volcanic eruption off Earth and carries the ashes of the man who discovered the dwarf planet
• recent Horizons clocked the fastest launch ever recorded when it blasted off in January 2006, exceeding 36000 miles per hour. The spacecraft passed the Moon after just nine hours and reached Jupiter the following year. It took just three minutes to cross the diameter of Pluto.• The first images beamed back expose that, and at 2,370km (1473 miles) in diameter, Pluto is slightly larger than previously believed. This makes it undisputedly the largest dwarf planet in the solar system. For the past decade astronomers had been undecided about whether this title belonged to Pluto or Eris, or another planetary thing beyond Neptune,although Eris still has a bigger mass.
