(SeaPRwire) – By: James Vance. NASA astronauts were shifted to a Dragon spacecraft Friday after an air leak hit the ISS. Russian cosmonauts worked to fix leaks in the Zvezda module’s PrK. Roscosmos found two leaks; one was sealed with sealant. Leak rate doubled to nearly 1 kg/day. Pressure stayed stable. Later, astronauts left the Dragon and resumed station ops.
