1st flight of NASA's Mars helicopter Ingenuity delayed
By Meghan Bartels 11 minutes ago
The little chopper is grounded until Wednesday (April 14).
NASA has delayed the first flight of its Mars helicopter Ingenuity after the vehicle's last test ended earlier than planned.
Ingenuity will now remain planted firmly on the Red Planet's surface until at least Wednesday (April 14), according to a statement from the agency. The delay comes in response to an anomaly during a test that was meant to see the helicopters blades reach flight-like speeds of 2,400 revolutions per minute.
"During a high-speed spin test of the rotors on Friday, the command sequence controlling the test ended early due to a 'watchdog' timer expiration," NASA officials wrote in a statement published today (April 10). "This occurred as it was trying to transition the flight computer from 'Pre-Flight' to 'Flight' mode. The helicopter is safe and healthy and communicated its full telemetry set to Earth."

    美国航天局的火星直升机首次飞行推迟
    梅根·巴特尔斯11分钟前写的
    小直升机停飞至星期三(4月14日)。
    美国宇航局推迟了火星直升机的首次飞行,因为该飞行器的最后一次试验比原计划提前结束。
    据该机构的一份声明称,至少在星期三(4月14日)之前,这颗红色星球的表面仍将牢牢地种植着创造力。这次推迟是为了应对一次测试中出现的异常情况,测试的目的是让直升机的桨叶达到每分钟2400转的飞行速度。
    美国宇航局官员在今天(4月10日)发表的一份声明中写道:“在周五进行的转子高速旋转试验中,由于‘看门狗’计时器过期,控制试验的命令序列提前结束。”这是因为它试图将飞行计算机从“飞行前”模式转换为“飞行”模式。直升机是安全和健康的,并将其全部遥测设置传送到地球。”
