I remember doing qualification and life test of Faichild CCD143A. It was wonderful to do it and get 20m resolutiion image from low earth orbit satellite.

Susequently it was more powerfull CCDs and now it is microwave remote sensing.

imaging in space

Thanks for this good article. I was reminded of something similar when I was covering a show in Yokohama, Japan last week.

I saw NEC's image compression algorithm, called StarPixel at the show. It was apparently adopted by the Japan Aerospace Exploration Agency (JAXA) for use in the Venus Climate Orbiter AKATSUKI a few years ago.

I was told that while it took 60 seconds for JPEG 2000 to do lossless compression on a very large image file, it took StarPixel one second. Various constraints working in the space certainly give opportunities for developments of new technologies.

And here's the link to the show -- ET2013 -- I covered in which StarPixel is mentioned:

I am also interested in knowing current state of CCD imagers for physical research application like spectrmeters working at 20Kelvin.

Thanks for this artilce.  I agree with everything in this article except the year of 1969.  I believe that 1968 was the year that laid down the groundwork to ensure that we were successful in 1969.  The first was that re-application of hardware developed for Apollo. This was the approach proposed for the Apollo Applications Program (AAP), which had been endorsed by President Lyndon B. Johnson in 1964-1965. Once again, wonderful article.

I don't think anyone misses those old image orthicon tubes. Thank goodness for both CCD and CMOS image sensors!

Greetings over your Orthocon Tube

I miss the quality of some of the programs that were shot using orthocon tubes.  I only occasionally watch 21st Century television, and it becomes clear within seconds that I'm "not the target demographic".

Much more amusing to see Ernie Kovacs as Percy Dovetonsils, poet laureate, saying "Greetings over your Orthocon Tiube" with that wonderfully silly voice and glasses.
