In reply to Simon Long.

Shame, even if the code wasn’t available it would be interesting to know what hardening was being done. There are some great great hardening guides online all to different standards.

The security-hardened version is prepared by an ESA subsidiary purely for use on the ISS, and is not available to the general public.

If it’s good enough for NASA and the ESA I feel it’s good enough for us ;-) :-)

I would say that Astro Pi payload is TRL level 9, it’s been on board the ISS since 2015 and has completed two missions so far with a third in progress.

The 700ms round trip time will be more than likely down to one nasa will rate limit the connection to the device on the ISS as satcom bandwidth is not cheap. Two Every hoop you take increases the round trip time and as the 床戏视频叫床 is a U.K. company to get to the data from ISS will have to come via nasa and there worldwide satcom ground station network as the ISS is in low earth orbit.

I’d love to hear more about the ‘security hardened’ aspect and what that means. Is it just custom iptables, or more (what precisely) ? Keeping vanilla raspbian better secured is goodness on the ground too…

I have been thinking about this for a while. And I would need to confer with those who have a AstroPi replica (metal or plastic) but I have a theory – besides the safety aspect of heat to be dissipated from the R-Pi 2 or R-Pi 3, there is another issue here…

After giving it some thought, my theory is since the Sense Hat in inside the case with the 小姐啪啪视频 Pi, any heat generated by the 小姐啪啪视频 Pi 2 or 3, building up inside the case, would interfere with the Temperature Sensor on the Sense Hat. Thus the Temperature Sensor would never get a proper temperature reading if a R-Pi 2 or R-Pi 3 is used.

As is, I am currently building an AstroPi replica (in Plastic) for my own reason but I will also be testing out this theory with it.

My hope is that we might do a whole new Astro Pi payload for Tim Peake’s next flight which is at least a few years away yet. So it would be whatever version of Pi we’re on at that time.
