T+ 394 Days Engineering Log

Our Lunar Orbit insertion burn was performed using a combination of 8 EHEs over the course of 2 hours. It was decided not to use any EHE for more than 30 minutes at a time for a long duration burn. Exactly why our EHEs failed during the Earth Closest Approach burn is still under investigation but preliminary analysis shows that the initial 4 EHEs overheated during the long burn and this caused some sort of explosive event which caused damage to nearby EHEs. This information will be critical to know...

Early this morning we made our closest approach to Earth and with it our Earth Capture burn. This was by far the longest EHE burn of this mission and we had a few issues with 2 of the 4 EHEs chosen for the burn. We were only able to complete the burn by switching to alternate EHEs in mid burn. Currently we have 5 EHEs out of 17 unavailable for future use in this mission due to damage caused by the 2 EHEs failing. Determining exactly what damage was caused and how to fix it will have to wait until...

The easiest things to do...

... Are the hardest to compute. And that truth hit me hard. So hard when I went to the barber the other day, she had a look at my hair and said "Whoa, you're losing your hair already, baldness is getting to you!" (true story). The thing was I knew that already. Because that thing made me pull my hair out.


That thing, is Tile Maker. It's an idea I have over a year and a half ago, that I started coding,...

Linux + ZFS

Posted 02-25-2016 at 07:26 PM by Lisias

Preamble
I can't find a more convenient and relevant place to save this article than here, on the other hand given the results of the last Forum thread I was involved about the issue, I'm reluctant to do it openly in a way that would trigger another flame-fest.

So this post will be blocked from comments, and I will not engage in any public discussion about the matter.

The issue
Apparently, there's a licensing issue on the planned ZFS support for Ubuntu....

Phasing burns began today and will continue until we make our lunar insertion burn in 2 weeks time. We are cycling through our collection of EHEs using a different set each burn. After 1 day of burns we have had no issues with any of the EHEs.

These phasing burns are a practice of sorts for the burns that will be made by SSTV-02 when it arrives at Pluto after a 100 day transit from LEO and when it arrives back to the Earth-Moon system again after a 100 day transit from Pluto. The...
