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.
如果宇航局要控制来自地球的信号，他们可能需要16分钟去观察每条轨道。
The crew's time would be slowed down by half. For every 16-minute orbit, they'd only experience eight minutes of time.
太空船的时间将滞后一半，16分钟的轨道，他们仅需要8分钟。
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避开了这个故障，负载整流罩保护着卫星与推进器分离，保证卫星进入轨道。

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.
