d orbit

基本解释

If a space agency were controlling the mission from Earth they'd observe that each full orbit took 16 minutes.
如果宇航侷要控制來自地球的信號，他們可能需要16分鍾去觀察每條軌道。
The crew's time would be slowed down by half. For every 16-minute orbit, they'd only experience eight minutes of time.
太空船的時間將滯後一半，16分鍾的軌道，他們僅需要8分鍾。
But Aquarius/SAC-D steered clear of that problem, and the payload fairing protecting the spacecraft separated and fell away as planned, allowing the craft to enter orbit.
水瓶/SAC-D避開了這個故障，負載整流罩保護著衛星與推進器分離，保証衛星進入軌道。

This week we saw new horizons dawn for green transportation as NASA's Nanosail-D became the first solar sail spacecraft to orbit the earth and President Obama issued a call for one million electric vehicles in his State of the Union Address.
