LEGO has teamed with NASA to sponsor the NASA Missions: Imagine and Build contest. Two categories: 1. Build a MOC based on an actual planned NASA mission. 2. Design the aircraft of tomorrow, accompanied by a technical paper. The age ranges (16+, 13-18, and 18+) and the requirement for a technical paper indicate that they're looking for some serious work here, not some kid's rainbow warrior project, so this should result in some great builds.
