NASA has two new Centennial Challenges:

The space agency is challenging innovators to build an autonomous aerial vehicle to navigate a tricky flight path or robots capable of building complex structures with only limited guidance from their human handlers, NASA officials said.

I hope that a few of these start to pay off soon, to provide incentive to start spending a lot more money on them. Right now, by my count, they’re spending about a hundredth of a percent of the agency’s budget on them.

Leonard David also has a report on a recent space tourism roundtable in California. The giggle factor continues to dissipate.
