NASA has expelled a breathtaking image of Earth and a moon taken from a spacecraft in circuit around Mars from 205 million kilometres away.
The picture is a combination of 4 sets of images taken on Nov. 20, 2016 by NASA’s High Resolution Imaging Science Experiment (HiRISE) booster that has been in circuit around Mars given 2006.
The sketch shows Australia nearby a centre, with Antarctica as a bright white mark in a bottom left.Â
In sequence to acquire a image, a satellite total information from a red and blue-green spectrum (the camera can also picture in a infrared) and processed them as red, green, and blue.
The booster also had to take dual apart exposures: one for a moon and one for Earth, as they change in brightness.
The booster has been holding high-resolution images of Mars from an altitude that varies from 200 to 400 kilometres. The images are so minute that they can uncover features just one to two-and-a-half metres across.Â
HiRISE took a picture as partial of the calibration process.
