NASA engineers end second super pressure balloon flight early

Flight path of second super pressure balloon test
Due to an issue with its power system, NASA engineers today decided to end its second super pressure balloon flight this year after only nine days, when the balloon crossed over South America and thus allowing them to recover it safely.
Although the balloon performed well and the mission successfully met its minimum requirements toward qualification of the balloon system, an issue with the power system aboard the balloon gondola prompted the team to terminate the mission early as a precaution. The team had been monitoring a power failure in one of the redundant charging systems since May 8. “Despite the loss of one of the redundant charging systems, the remaining power system was performing very well and still able to sustain the batteries and electrical equipment over the course of the mission,” said Hamilton. “However, to be cautious, the team opted to end the flight early to get the equipment back, so we can do a full failure analysis.”
After identifying a safe area and coordinating with Argentinian officials, the flight was safely terminated. Recovery of the balloon and payload is in progress.
The first flight flew for seventeen days, circling the globe at the high southern latitudes. In that case issues with the balloon caused the flight to be terminated while it was over the ocean, preventing recovery. As the goal with both flights was to fly for 100 days, neither came close to that target.
