NASA HIGH-FIVE FAIL

The NASA engineers went NUTS when the new Mars rover touched down on Sunday. You've probably seen the video by now, but there's something you might have missed: Two engineers in the background tried to high-five and FAILED.

It happened really fast, but the video's online. Obviously it's ironic, since they'd just help land something on Mars, 154 million miles from Earth.

NASA also had high-five issues back in 2009, when they shot a rocket into the moon to look for water. There's video of an engineer who tried to high-five someone, but they left him hanging.
