After launching Mangalyaan in a blaze of publicity last week, the Indian space agency is now under pressure to deliver a successful mission. A transfer to mars requires the probe to fire its engine several times pushing itself further and further from Earth with each step. But in the fourth of these engine burns, the spacecraft achieved only 25% of the expected distance.______________________________ No one is yet raising the alarm over the status of Mangalyaan. But engineers all want to see a perfect maneuver from their probe to settle any nerves. 在上周广受关注地发射了曼加里安号火星探测器之后,印度航天局面临着成功地完成一项太空任务的压力.向火星传送的过程中需要探测器数次点燃携带的引擎,从而逐步将其推向离地更远的轨道.不过在引擎第四次点燃时,太空船仅仅推进了其预期距离的25%._________________________________尚无人就火星探测器的情况发出警报.不过工程师们都希望看到他们的探测器完成一项完美的任务,以安抚任何紧张的神经.
