The NASA New Horizons probe, which is flying to Pluto, failed on July 5 and lost contact with the Earth Control Center for more than an hour, but then resumed communications. At this time, there is only about 10 days left before the historic spacecraft flies over Pluto.
Beijing time on July 6th news, comprehensive NASA related reports, NASA New Horizons probe that is flying to Pluto failed on July 5, lost contact with the Earth Control Center for more than an hour, but then resumed Communication contact. At this time, only about 10 days left before the historic spacecraft flew over Pluto, the fault was of great concern.
At 13:54 on July 4th, US Eastern Time (01:54 am on July 5th, Beijing time), the New Horizons Detector lost contact with the Earth, and then at 15:15 EST (Beijing time, July 5, early morning 03) :15) Resume communication links.
In the status update, the New Horizons Detector project team wrote: "At that time, the spacecraft's automatic navigation system identified a problem and automatically switched from the host computer to the backup computer according to the preset program." The project team indicated that the current state of the new horizons spacecraft is still in good condition. The project team stated: “The automatic navigation program puts the spacecraft into 'safe mode' and instructs the backup computer to restart communication with the Earth. The new horizon detector then begins transmitting signals to the Earth so that ground engineers can diagnose the problem. ."
At present, a “fault assessment committee†is investigating the problems that have occurred, and at the same time, the New Horizons spacecraft is released from safe mode and resumes normal work. The mission official said that the recovery work may take several days, because it takes up to 4.5 hours for the signal to travel one-way from the spacecraft to the Earth. At present, the distance between the New Horizons detector and the Earth is more than 4.8 billion kilometers. The project team wrote in the status update announcement: "In the meantime, the new horizon number will not be able to collect scientific data. Once new information is available, we will announce it in time."
The New Horizons detector project cost more than $700 million and was launched in January 2006 with the goal of becoming the first Pluto detector for humans. On the 14th of this month (July 14, 2015), the spacecraft will fly for only the first time from Pluto, about 12,500 kilometers away, which is nearly 30 times longer than the distance between the Earth and the Moon.
As the Pluto system gets closer and closer, in the past few weeks, the New Horizons Detector has sent back a lot of wonderful images, unraveling the mystery of Pluto, a distant planet, and flying at close range. The vast amount of valuable scientific data that will be collected during Pluto is even more exciting. Scientists are eager to know a lot of things, such as what the image shows on the surface of the dwarf planet near an apparently circular dark area near the equator. According to the latest image, Pluto shows a reddish tint, and its largest satellite, the Guardian Card, has a gray tone. (
