Message to Edit: HTML is ON UBB Code is ON Smilies Legend	Originally posted by Robert Pearlman on 09-10-2011 12:37 PM [QUOTE]Originally posted by Fezman92: [b]Why will it take so long for GRAIL to get to the moon?[/b][/QUOTE] From NASA's GRAIL launch blog: <BLOCKQUOTE>[i]The GRAIL spacecraft will not go directly to the moon, but instead are taking a circuitous route that calls for them to loop out deep into space on a journey that will cover about 2.6 million miles and take three-and-a-half months. By taking the longer path, the spacecraft don't have to use much fuel to slow down and go into lunar orbit. Apollo capsules carrying astronauts took three days to reach the moon, but they had to fire their braking rocket to go into lunar orbit.[/i]</BLOCKQUOTE>
