MMOS are currently investigating an issue with Project Discovery.
It appears that during the evaluation phase (after the tutorial) data sets that are presented for analysis are too difficult for that stage. This has led to many players being given extremely low overall accuracy.
While this has caused some concern among players, we will not be shutting down Project Discovery. Samples are still being assessed correctly, and once past the evaluation phase players are still able to continue assessing and completing samples.
A fix will be deployed tomorrow after downtime, which will update the data sets to a more reasonable one for the purposes of evaluation, and reset to 50% all Accuracy Ratings for players who have it below 50%.
We will publish another update once the fix has been deployed.
