In chemistry, a singlet refers not to a single atom, but to a configuration with equal numbers of “spin up” and “spin down” electrons. This is the case for the ground state of many molecules (such as H2), but not all molecules. O2 is probably the simplest and most well-known example, with the electron configuration being most stable in the triplet state.

(This is a downrange distance record for fairing recovery by ~110 km) The previous record was ViaSat-3.1 at 1955 km.
