The Centennial Challenges website has been updated a bit. The changes I noticed are in the detailed page for all of the Challenges. Each Allied Organization that actually runs the competitions has their own style of website, and it appears that the Centennial Challenges page is providing a consistent way to find similar types of information, as it becomes available, across all of the Challenges. For example, the NASA page has "Competition Venue" and "Venue Directions" links in cases where this has been determined.
The 2007 Astronaut Glove Challenge and 2007 Regolith Excavation Challenge are fast approaching. The first event is scheduled on May 2-3, at the New England Air Museum, and the second is scheduled on May 11-12, at the Santa Maria Fairpark.
