Scientists made an antimatter qubit made from an antiproton that is in a state of quantum superposition. This breakthrough will allow the strength of the particle's magnetic moment to be measured with unprecedented precision.
From an engineering perspective, space is surprisingly hot. Or, more specifically, solar energy can make systems that need to be kept at a very cold temperature heat up much more quickly than expected, given the reputation that space has of being cold. In some cases, this heating causes issues with long-term missions, which is why NASA is actively testing a two-stage active cryogenic system to keep one important consumable as cold as possible - fuel.
