China releases images of Earth and Moon, taken by its Tianwen-2 asteroid probe
For original images go here and here.
According to a report today in China’s state-run press, its Tianwen-2 asteroid sample return spacecraft is operating normally, and has successfully taken pictures of both the Earth and the Moon to test its instrumentation.
Those images are to the right, cropped, reduced, and sharpened to post here.
The CNSA [China National Space Administration] said that the narrow-field-of-view navigation sensor equipped on the probe recently captured the images of Earth and the moon, demonstrating good functional performance.
The images released include a photograph of Earth obtained by Tianwen-2 when it was approximately 590,000 kilometers away from the planet, as well as a new photograph of the moon captured when it was about the same distance from the moon. After the images were transmitted back to the ground, they were processed and produced by scientific researchers.
The Tianwen-2 probe has currently been in orbit for over 33 days, at a distance from Earth exceeding 12 million kilometers, and it is in good working condition, the CNSA said.
The probe will take about a year to reach asteroid Kamo’oalewa, where it will fly in formation studying it for another year, during which time it will attempt to grab samples by two methods. One method is a copy of the touch-and-go technique used by OSIRIS-REx on Bennu. The second method, dubbed “anchor and attach,” is untried, and involves using four robot arms, each with their own drill.
