You can monitor a variety of flight aspects at the SolarImpulse.com website. On Monday however, during the first leg of a planned global circumnavigation, the website went offline.
You can check the Solar Impulse 2's battery status, including whether they're charging in the sun or discharging to power the plane's four electric motors.
The first trip in the round-the-world effort heads east from the United Arab Emirates to Oman. The batteries charge en route, a key part of the technology necessary to carry the plane through the night.
