And Gaia also has a downlink speed of approx 3Mbps. So it will process as much as possible on board and just send down less than 20 pixels per each star imaged. That is why you can not get a direct image out of it.

It takes about 14 pictures of each star during orbit (which is quite close to Earth’s orbit around the Sun), so approximately once per month, and then compares those to calculate the star’s distance from the parallax.

The direction of flow is reversed every 30s. The cycle is short enough that due to the thermal mass there is thermal gradient within the heat-exchanger. So it effectively works as counter-flow heat exchanger. Same principle (but continuous

5110 was fantastic. I did not realize this before, but about 10 years ago needed a replacement phone quickly and had an old 5110 in storage. Charged up, powered up, switched on and in less than 10 seconds could make a call. Fantastic bootin

Have used that JFET trick on large area photodiode amplifiers in a satellite based radiation detector. Works quite well. Also quite similar is actively driving the shield used in many high impedance sensor circuits (most notably capacitive

If the computer here is 20 years old, then we are talking about PowerPC based Mac. So two transitions over this devices lifetime: PowerPC -> Intel -> ARM.

You are correct. 22*1.4 + 10 is, my bad.

22 dB/cm/MHz, 1.4cm, 10 MHz gives ~40dB, which happens to be 4-orders of magnitude difference in power. Not sure how they got 14 orders of magnitude for the attenuation.
