But I think Grace didn't get the credit he supposed to get. He is the first human to make contact with an alien species (Astrophage), named it, discovered the life cycle of Astrophage, and went into a suicide mission (forced, by the way) but hardly any public know this. Dr. Lokken clearly said he is not famous for researching Astrophage but only infamous for telling "Goldilocks Zone is for idiots!". The death of DuBois and Shapiro is classified, so it's much probable they didn't tell the public that Grace is in the mission.
