ISEE-3 Reboot Project Update: We Have Telemetry Data and an Engine Firing Date

300px-ISEE3-ICE[1]If we can maneuver the spacecraft by June 17th we get the very small delta V number for the maneuver above. However, this starts to climb rapidly as the spacecraft gets closer to the moon. Also we cannot at this time rule out a lunar impact.

It is imperative that we get a ranging pass as soon as possible. We also need time to not only evaluate the health of the spacecraft, but to test the systems, the catalyst bed heaters for the propulsion system, the valve heaters, analyze the rest of the propulsion, power, and attitude control system as rapidly as possible.

This will be a lot of commanding so we have to move into high gear next week. This is a very fluid situation and we have made amazing progress, thanks to the support of those who believed in us in our crowd funding and the support of our NASA sponsors at NASA Ames and NASA headquarters. More to come soon!!”

Good luck on one of the more interesting space efforts going.

I had some command, control, and telemetry experience with Intelsat III geosync communication satellite in the late 1960s..t’was a bit nerve wracking for me at times as I remember. ..

Excuse me if this seems a bit dense, but why isn’t Bruce Willis or Keir Dullea up there trying to fix it, instead of all this crazy radio stuff?

The suspense is delicious.

I hope NASA gives you all the support you need in this unique space effort.
Better than chasing global warming fairies…

Wow! This is such a nifty project! It’s an engineer’s dream. Godspeed.

So cool. I know a 4th grade student who would just die to know about this. He can’t write but he knows what goes into a computer chip. I love kids like that.

I’d be very careful to miss the Moon. On top of the very expensive hole you’d create, the EPA would be on your back for not handling hazardous waste properly….(sarc)
Seriously though keep up the good work nice to see ingenuity, knowledge and hard work still pay dividends.

Sleep is overrated. Keep up the amazing work.

They’re decoding bits and bytes Commodore 64 style. That’s awesome. I remember the disk drive would have its own CPU (same as in the C64 itself) and would be used to decode the data coming from the disk. 5 bits were encoded for every 4 bits stored in memory. This meant certain combination were impossible and if you reached those, you knew you had an error. There were also header and footer indicators. The streams from the satellite seem to use a similar technique.

It keeps getting better and better!
Best of luck, simple prayers, and high praise to your team!

Keith and Dennis,
I am very pleased to see you making so much progress on such a great endeavor!!!!
I would be willing to make another larger contribution should you guys decide to tackle the misdirection of the USA. I am sure you could do the impossible with very little… 8>)~

Another step towards world domination.

Incredible stuff. I’m glad that NASA seem to realised that they’d to better being associated with this kind of work that climate modelling.
It’s great that you are able to tap into the excellence that prevailed at that time.

“I would be willing to make another larger contribution should you guys decide to tackle the misdirection of the USA. ” LOL
I’m not sure that there enough natural resources left on the planet to put the US of A back on course !

Spiralling spacecraft headed for moon.
Spiralling moon in June sweet lovely tune.
Spiralling both do not kiss.

Also we cannot at this time rule out a lunar impact.
What mass and speed and angle would be needed for a suitable object that impacts the Moon, to throw up enough ejecta of the right sort for a sun-shielding “dust belt” around our planet, that will allow this overheated sphere to cool?
I’m wondering as I’m getting bored waiting for this interglacial to end, and for the mile-thick ice to once again cover this land. Then I won’t have to mow this grass.

What are the applicable laws regarding lost or abandon spacecraft? Do the laws of the seas apply, if a spacecraft is lost or abandon then found or salvaged, does it then become the property of the the finder in control? Are there any legal controlling authority in Space? Considering all the precious metal and valuable electronics on a spacecraft the salvage, reuse or conversion to another use could be a lucrative business.
