Weekly Update 8.6.2012 - Space Florida for the Nanosatellite Launch Challenge, with a brief note on rule changes and sponsors. There isn't much activity on the forum, but there is now an effort to make an external forum for the competition: Nano Sat Launch Pad. SpaceRef posted the following RFI from NASA on the challenge: NASA Request for Information: Centennial Challenges Nano Satellite Launch Challenge. Here is an excerpt discussing possible big changes to the competition, which started as a $2M competition, and is currently for $3M:
Several approaches to the NSL Challenge are being considered by NASA. In
one approach an initial competition would require delivery of payloads
to LEO twice within a one-week period using a launch system sized to
deliver up to 10Kg to LEO. The competition would be for one year and a
$3M prize purse would be divided between all successful competitors.
Subsequently, a second competition would be held that would require
successful competitors to deliver payloads to LEO at least ten times
within a one-year period using a launch system sized to deliver up to
10Kg to LEO. A total prize purse of $6M would be offered for at least 10
successful payload deliveries: 1st Place receiving $3M for most
deliveries; 2nd place, $2M for next most deliveries; and 3rd place, $1M
for next most deliveries. ... An alternative approach to the NSL Challenge would be initially to focus
on component and subsystem technology development. In particular the
avionics for small launch vehicles is considered a significant cost item
and novel approaches will be required to achieve a launch cost that is
attractive to most nano-satellite developers. This phase would be
followed by launch vehicle demonstration competitions along the lines of
the approach described above.

Lockheed Martin Launches Innovation Contest - SpaceRef:
The "Innovate the Future" contest creates a global forum for interested
participants to share their ideas on how innovation can enable a more
secure future for the planet. Participants are invited to submit their
thoughts on a range of topics facing the world community, including the
need for sustainable energy, cyber security, and healthcare. ...
There will be up to one $25,000 grand prize, one $10,000 second place
prize, and three $5,000 third place prizes. The grand prize winner will
also receive an incubation contract with the Maryland Technology
Enterprise Institute at the University of Maryland to help validate and
develop the idea.
