2. Science Payload and Advanced Concept Office (SCI-A) L. Duvet SDW2005, Taormina, Sicily 22/06/05 Evolution of APS for space application at ESA Active Pixel Sensors have been identified during assessment studies as reference technology for the remote sensing imaging payload on board: -Bepi Colombo (2012): mission to Mercury -Solar Orbiter (2013): sun observation So far the use of APS for space applications has been restricted on: -STAR tracker: STAR 250, IRIS3, STAR 1000 sensors (soon in the EPPL). -VMC (Visual Monitoring Camera): separation phases Soyouz, Ariane V Recent progress + Mission constraints Star1000 chip

3. Science Payload and Advanced Concept Office (SCI-A) L. Duvet SDW2005, Taormina, Sicily 22/06/05 Bepi Colombo Bepi Colombo mission: take-off in 2012 toward Mercury with two orbiters (MPO, Mercury Planetary Orbiter, MMO (Mercury Magnetospheric Orbiter) The 4 instruments are APS based (CCDs as backup). Two developments funded by ESA will be initiated in the industry in the following months: - optical APS: 2k 2, 10 um, 400 nm to 900 nm, high QE, built-in 12 bit ADC, snapshot, < 15 e- read noise, 100 krad TID, SEU/SEL immune.  ITT publication imminent (DOPODOMANI!) - optical-IR APS: 512 2, 20 um, 500 nm to 2200 nm, operating temperature 200-230 K, 100 krad TID, SEU/SEL immune.  ITT published on the June 10 th, 2005. SYMBIO-SYS (PI: E. Flamini, ASI) is the Remote Sensing Imaging consortium on board MPO. It consists in: HRIC (High Resolution Imaging Channel): 5 m/pxl @ 400 km, 400-900 nm STC (Stereo imaging Channel): 100 m/pxl, 500-900 nm HIRIS (High Resolution Imaging Spectrometer channel): Fourier Transform spectrometer, 588.5-590 nm VIHI (Visual and Infrared Hyperspectral Imager channel): 100 m/pixel at 400 km, 400- 2200 nm

4. Science Payload and Advanced Concept Office (SCI-A) L. Duvet SDW2005, Taormina, Sicily 22/06/05 Solar Orbiter Solar Orbiter will be launched in Oct. 2013 for an 8 year extend mission, observing the sun as close as 45 sun radii, with increasing inclination. The preliminary payload is also based on APS and at least two dedicated technological developments are foreseen (Q1 2006), they will focus on: - Radiation hardness (nominal environment equivalent to modest storm encountered by SOHO). - Increased EUV sensitivity (Hybrid or backthinned monolithic) as replacement to intensified CCDs. - Solar blindness. - Pixel size down to 8 - 5 um. - Low dark current & low temperature operation (typ : -80 Celsius). The preliminary remote sensing payload consists in: VIM (Visible Light Imager and Magnetograph): 400-700 nm EUS (Extreme Ultraviolet Spectrometer): 17-100 nm EUI (Extreme Ultraviolet Imager): 13.3 nm, 17.4 nm, 30.4 nm COR (Coronograph): 450-600 nm( 121.6 and 30.4 nm optional)
