Another day, another failed attempt to forward space technology. Less than a week after the Space Elevator Games concluded without a winner, the X Prize Cup followed suit. The much favored Armadillo Aerospace—the only one of nine entrants ready by the start of the event—dashed hopes when their lander exploded while still on the launch pad. Accordingly, no one walked away with the $350,000 Level 1 purse, leaving our LANDR proposition (trading in the mid-60s at the start of the competition) to close out at $0. Sorry space fans, better luck next time.—Abby Seiff
