According[1] to NASA's Richard J. Burley, as of just after midnight UTC Jan 25 2018, they haven't yet attempted communication using DSN, but they're working on it:
> I have attached the TLE I got this morning from JSPoC/CARA. Looks like a close match. We are in the process of engaging the Deep Space Network to see if they can get a signal lock. They (JPL/DSN) are in the process of digging up 13-year old configuration files for that attempt. The DSN has evolved since then so some adjustments to their system setups will be required.
> I have no schedule estimate yet for when that first attempt will be made. If we are able to get signal lock and verify that it is IMAGE, we will setup a MINIMAL ops setup to verify telemetry/command and make an initial assessment of the health and viability of the spacecraft bus. I don't have a credible schedule prediction yet for that step either.
> Thank you for all of your efforts for IMAGE. IMAGE made ~39 new discoveries about the Earth's magnetosphere and plasma-sphere. At the time it stopped radiating, NASA HQ ranked IMAGE as the 2nd most valuable space-physics mission flying. A follow-on mission called MMS, with a 4-spacecraft constellation is currently flying, in part, to follow up on these discoveries.

- Maxious 9y agoFollow up! > I just received official confirmation from NASA that IMAGE is indeed alive! See Below! > Engineers at GSFC have acquired the suspect S-band source using the 4m CTA (Compatibility Test Antenna) here at GSFC (.jpg attached and no I’m not in the picture). They acquired the signal while the target was on ascent at about 2RE. Center frequency (CF) was between 2272.478 and 2273.418. The difference between IMAGE documented CF of 2272.5Mhz can be attributed to expected Doppler. Subcarriers are visible as well 1.7Mhz from CF as expected. The signal strength was oscillating. Plots will be forthcoming. The oscillation is not unexpected given IMAGE’s loss of spin balance. > All indications so far suggest that this is, in fact, IMAGE. http://www.satobs.org/seesat/Jan-2018/0203.html http://www.satobs.org/seesat/Jan-2018/0203.html
