We spent all day yesterday with space propulsion experts. We have identified a series of options including hydrazine tank heating and a long series of pulse attempts to (possibly) clear the lines….

We have a crowdsourced research project for our ISEE-3 Reboot fans. One of our volunteers, Karl-Max Wagner from Germany has an interesting idea. Did the Nitrogen pressurizing gas dissolve in the Hydrazine…

Our troubleshooting today eliminated some suspected causes of propulsion system problems. We do not think any of the valves are malfuctioning. Right now we think there is a chance that the Nitrogen…
