From the AMA with CCP Hellmar:
Can we get an update on Project Discovery, and the future of this type of mini-game?
You guys are still pounding away at exoplanet discovery and providing reams of data! I personally just crossed over 95% accuracy rating and love doing it. Mining in EVE, doing Project Discovery and listening to science podcasts is my favorite meditation activity.
We don’t have anything to announce regarding a next phase for Project Discovery right now. Once we do, we’ll let you guys know.
