"Moon Express, Inc. has received official verification today of their launch contract from XPRIZE as part of the $30M Google Lunar XPRIZE, a global competition for privately funded teams to land an unmanned spacecraft on the surface of the moon by December 31, 2017. Moon Express will use a Rocket Lab Electron rocket combined with the company's "MX-1E" micro-lander as part of a 2017 mission."
Google Lunar X Prize to Verify Moon Express Launch Contract (October 2, 2015)
Here's what Chanda Gonzales, Senior Director, Google Lunar XPRIZE said on the contract issue "Our decision is based on a holistic assessment of whether the launch contract is genuine, whether there are any legal issues that might pop up, whether there are any obvious non-compliances with the rules, and whether a substantial commitment was made by both the team and the launch provider (e.g. non-refundable deposit of some certain minimum value)."
"At a press conference held in Jerusalem today, alongside Israeli President Reuven Rivlin, and Bob Weiss, vice chairman and president of XPRIZE, SpaceIL announced a significant milestone in its race to the moon: securing a "ticket to the moon" on a SpaceX Falcon 9 launcher, with a mission scheduled for the second half of 2017. With this, SpaceIL becomes the first team to produce a verified launch contract in the US$30 million Google Lunar XPRIZE competition, and aims to accomplish not only the first Israeli mission to the moon, but also the world's first private lunar mission."
Marc's note: So Moon Express announced their contract first but SpaceIL had theirs verified first. Each will claim they were first for history, but the only thing that matters at this point is that one or both and possibly more actually launch, make it to the moon, do something and build their business case.
