Less is More S. R.Kulkarni Director, Caltech Optical Observatories Chairman, SIM-Lite Science Team
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 Russia US
Satellites by countries
Telemetry is Inexpensive And the price will fall ….
CHIPSAT “Cosmic Hot Interstellar Plasma Spectrometer” The only UNEX mission to date 63 kg satellite EUV spectrometer for diffuse ISM (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 satellite 5-cm telescope 3-axis stabilized 1-micron imaging and astrometry Launch 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”
