ALTAIR

The ALTAIR project provides a precision [0(0.1%) uncertainty] photometric reference calibration using in-situ-calibrated light sources above the atmosphere, in the optical and microwave spectra.

ALTAIR will provide the means to eliminate the largest uncertainty in measurements of dark energy using supernovae, and (via an onboard precisely-polarized microwave source) a major uncertainty in the search for gravitational waves in the CMB, and additionally provides key information on atmospheric science.


Our partner project, ORCASat, will be launching a CubeSat "version" of the optical source of ALTAIR into low Earth orbit in 2022!  (ALTAIR itself will be simultaneously continuing with calibration flights using high-altitude balloons; the two techniques are quite different and complementary!)
