They say, "In light of the recent observations and the available facilities in Bochum, additional studies about the economic feasibility to add a suitable uplink are being done." Unfortunately, I think this comes a little too late. Why didn't AMSAT-DL got active years earlier? Didn't they know of this opportunity?

A plot of the trajectory of ICE from January 2013 until 11 August 2014, with the Earth fixed at 1,0. The red square is the position of the probe today.

From the JPL Horizon data, the closest approach will be on 9 August at 11.44 UTC at about 404,000 km.

it looks like an 18-meter satellite dish at the Johns Hopkins Applied Physics Laboratory still has the right hardware. "And so NASA has given them the approval to be able to try that out," Green says.

Great article, thanks. It's amazing (to me) that I can read the thing and think, "oh yeah, 1978 launch, clearly amazing/impossible/jawdropping." And then I recall that the Voyagers were launched in 1977, though they are RTG powered. I can't seem to find the longevity record for solar power.

There are some people in Germany try to get in contact with ICE.

The article contains links to some technical documents of ISSE-3/ICE:

Quite a way to go from receiving a signal to commanding a probe in the correct language.
Hopefully the teams will together be able to build kind of backup DSN for ISSE-3/ICE.

I have contributed, although it is a longshot. It would be a great story.

Latest news at http://spacecollege.org/isee3/isee-3-reboo...st-contact.html. Sounds like they're making good progress, considering the challenge.

They've now exceeded their initial fundraising goal, which is a good sign.

Note that this was simply a detection, something that was done by other groups back in March. If they transmit and get a response, then that will be news.
