Are we on the verge of a paradigm shift?
Access to Space will get Cheaper
Nearly a dozen space faring countries US, Russia, Europe China, Japan, India, Israel, In development: Iran, S. Korea, Brazil,
Taiwan…Entry of private players

Some Trailblazars
CHIPSAT
“Cosmic Hot Interstellar Plasma Spectrometer” The only UNEX mission to date
63 kg satelliteEUV spectrometer for diffuse ISM2003-2008 (death due to budget)
MOST (Canada)
60-kg satellite dedicated to precision photometry
Demonstration of lightweight attitude system
Official cost $10M(Launch cost $1M?)
Brite-Constellation
Nano-satellites (20-cm cube)Large FOV CCD camera (24 sq degree)Photometry of bright stars (4 mag)Expected launch date is 2011
In the works: (nano)Jasmine
20 kg satellite5-cm telescope3-axis stabilized1-micron imaging and astrometryLaunch is now August 2011 (Cyclon-4)
Challenge & Opportunity<60 kg in LEO
X-ray monitors (always a winner)An instrument in support of ground facilties
(PTF) UV Photometer NIR Photometer
Precision Photometry on Demand Transit Eclipse
Stare at Galactic Center, LMC, SMC, M31 etc
Sub-orbital Ops: UVA/Drones
Great advance in Unmanned Aerial Vehicles (UAVs, “drones”).
No pilot and so reduced cost (and mass)
“Eclipse-on-Demand”“Fly-to-suit Transit”
