To achieve 98 days total above Peru, the balloon made nearly 20,000 adjustments. Google's new wind-predicting algorithms have kept one of its internet-beaming air balloons aloft in Peru's airspace for a total of 98 days. Google's measure for success when it comes to Project Loon isn't just keeping balloons flying for 100 days, but ensuring they're not carried out to sea by air currents where they can't deliver wireless internet to the public. Project Loon, which sits in the X unit of Google's parent Alphabet, has used human-coded algorithms to determine how high or low in the stratosphere the air balloons need to be to catch a current that will take them in the desired direction. However, as Wired reports, updates to Loon's navigational system apply machine-learning techniques to the roughly 17 million kilometers of flight data it's collected to predict wind directions at different altitudes.
