A solar-powered plane has been grounded by damaged batteries for at least a few weeks after completing its record-breaking five-day journey from Japan to Hawai'i.
The Solar Impulse 2's team says the batteries were over-insulated and became overheated on day one of the Japan-Hawai'i leg.
The team said on Saturday that it monitored the situation throughout the flight but could not decrease the temperature.
The plane won't fly before the beginning of August as the team works to replace and repair damaged parts.
Solar Impulse landed in Hawai'i on July the 3rd after completing a 118-hour voyage that broke the record for the world's longest nonstop solo flight.
It's next headed to Phoenix as part of an around-the-world flight aiming to highlight the importance of renewable energy.
