TESS and its solar transit 16.8Mpixel camera

TESS's four identical cameras consist of a lens assembly with seven optical elements, and a detector assembly with four CCDs and their associated electronics mounted onto a single plate. where its 16.8 Mega Pixel CCD low-noise, low-power detector, I'm looking for the surface area of its CCDs, as its not the pixels but its size with TESS's 400W power unit, its running on fresh air as a comparison to Nikons full frame D850 45.7 Mega Pixel 36x24 CCD drains that power in a hour, TESS has to supply it for ten years of more. The D850 45.7 Mega Pixel 36x24 CCD puts TESS's 16. 8 Mega Pixel cameras in perspective https://tess.gsfc...ent.html Just think what Nikons D850 45.7 Mega Pixel 36x24 CCD camera is capable of mounted on top of TESS's camera assembly! and it only costs £3500,
£3500 is not even farthings in comparison to the cost of TESS's cameras!

An economic version of TESS launched every year for 1600 years

The point being, that I would say as a ball park figure the cost of TESS's is in the $$$Billions, this could be a way of getting of getting an economic version of TESS staying only a year of more in orbit with cameras of the calibre of the D850 45.7 Mega Pixel camera available on the high street round the corner in Cambridge for £3500, which would enable a commercially produced economic version of TESS costing bellow a million pounds sterling, and we could put one up every year at 1.6 dollars to pound is $1.6Blillion, that is an economic version of TESS launched every year for 1600 years!
