The record-breaking Solar Impulse plane will be grounded in Hawaii for at least two weeks because of battery damage.The record-breaking Solar Impulse plane will be grounded in Hawaii for at least two weeks because of battery damage.
The solar-powered plane over-heated its electrical storage units during the historic, five-day crossing from Japan. The solar-powered vehicle overheated its electrical storage units during the historic, five-day crossing from Japan.
Engineers are trying to fix the lane but are not sure yet if new parts will be needed to get the vehicle back up into the air again. Engineers are trying to fix the plane but are not sure yet if new parts will be needed to get it back up into the air again.
The delay makes it less likely that Solar Impulse will complete its round-the-world quest this year.The delay makes it less likely that Solar Impulse will complete its round-the-world quest this year.

If Solar Impulse cannot get to the US East Coast soon, the project team may find meteorological conditions for an Atlantic crossing in 2015 will have passed it by. If Solar Impulse cannot get to the US East Coast soon, the project team may find that the correct meteorological conditions for an Atlantic crossing are no longer available in 2015.
The vehicle's slow speed, light weight and 72m wingspan put significant constraints on the type of weather it can handle. And beyond August, the windows of opportunity to cross the second biggest ocean on Earth become few and far between.The vehicle's slow speed, light weight and 72m wingspan put significant constraints on the type of weather it can handle.

Pilot Andre Borschberg smashed aviation records when he steered Solar Impulse from Nagoya to Kalaeloa at the beginning of the month.Pilot Andre Borschberg smashed aviation records when he steered Solar Impulse from Nagoya to Kalaeloa at the beginning of the month.
Flying just on the power of the Sun, he completed the 7,200km in 118 hours.Flying just on the power of the Sun, he completed the 7,200km in 118 hours.
Not only did this set several new marks for manned solar aeroplanes, but it surpassed with ease the absolute aviation record for the longest solo flight in an un-refuelled vehicle.Not only did this set several new marks for manned solar aeroplanes, but it surpassed with ease the absolute aviation record for the longest solo flight in an un-refuelled vehicle.
But in achieving this mammoth feat, Mr Borschberg's plane experienced damaging overheating in its lithium-ion battery system. Although the units performed as expected, they had too much insulation around them, making temperature management very difficult.

The Solar Impulse team says it will issue another bulletin in the next few days when engineers have had time to assess the problems. If new parts are needed, it is not certain they will immediately be available.The Solar Impulse team says it will issue another bulletin in the next few days when engineers have had time to assess the problems.
