and engineers are puzzled as the craft is still operating normally. The AACS is responsible for keeping Voyager in the right orientation and making sure that its antenna is pointing toward Earth so that the spacecraft can transmit data. But now, the AACS is sending back data that...
6、On Aug. 15, NASA's enduring Voyager 1, already Earth's farthest-flung robotic ambassador, became the first spacecraft to reach a distance of 100 astronomical units (AU) from the Sun.───在8月15日,美国国家航天局的旅行者一号,已经是地球的最遥远的机器人大使。成为第一架抵达距太阳100个...
22. ThisVoyager1 image of Jupiter's moon Callisto was taken from a distance of 217,000 miles. 旅行者1号在 217 000英里的距离上所拍摄的的木卫4的照片。 youdao 23. Launched in 1977,Voyager1 now holds that distinction at 17.5 billion kilometers from the Sun. ...
One AU is the distance from the sun to the Earth, which is about 93 million miles or 150 million kilometers. Neptune, the most distant planet from the sun, is about 30 AU. NASA's Voyager 1, humankind's most distant spacecraft, is around 125 AU. Scientists believe it entered ...
Those units come in handy soon afterward, because the record next goes through the sun and the solar system planets to give their diameters, distance from the sun, mass compared to Earth (using the "e" unit from before) and how long each planet takes to complete a full rotation, compared...
data system (FDS), which among other things is responsible for preparing the data it receives from other systems before it is transmitted back to Earth. As at this point in time Voyager 1 is at an approximate 24 billion kilometers distance, this made for a few tense days for those ...
This and more are explained in the article below, which covers the operating principle of different LiDAR scanners and explains how distance measurements are transformed and combined into 3D point clouds. These provide the basis for many 3D mapping products used for different industry applications. ...

Voyager 2 is a little less than 11 billion miles (about 17.7 billion kilometers) from Earth, or more than 118 times the distance from Earth to the Sun.
Communicating with Voyager 2 is challenging due to its location in the southern part of the solar system, and its extreme distance from Earth (roughly 120 times that between the sun and the Earth). Voyager 2 transmits with a power of just 20 watts. By the time the signal reaches Earth ...
