✦ Synopsis

A new type of telescope with a wide field-of-view and functions of fast zoom-in has been introduced. Two kinds of MEMS (Micro-Electro-Mechanical Systems) micromirrors, digital and analog, are used for reflectors of the telescope, placed at different focal lengths. We apply this technology to the observation from space of TLE (Transient Luminous Events), extremely large transient sparks occurring at the upper atmosphere. TLE are one type of important backgrounds to be understood for future space observation of UHECR (Ultra-High Energy Cosmic Rays). The launch of the payload carried by a Russian microsatellite is foreseen in the middle of 2008.

We report a search, at wavelengths between 402 and \(850 \mathrm{~nm}\), for anomalies in the Venus polarization curve near the \(22^{\circ}\) halo scattering angle for ice crystals (phase angle \(158^{\circ}\) ). Such anomalies, if present, can be interpreted as due to halo birefringence peaks. Ano

We report the design, space-qualification and flight performance of a 3 He refrigerator that has achieved the first sub-Kelvin temperatures in orbit. The refrigerator has been used to cool the bolometric detectors of the Far Infrared Photometer (FIRP) on the Infrared Telescope in Space (IRTS). The r
