A photo shoot of the Rover Curiosity from Mars was what gave rise to several images that show Earth and Venus with “the naked eye”.
In the images captured by the NASA robot, both planets are seen aligned as simple points of light, due to a combination of distance and dust in the air that allows them to be seen as very bright stars.
“Curiosity’s plan was to study the brightness of twilight , because during this time of year on Mars, there is more dust in the air to reflect sunlight, making it particularly bright”, said Mastcam co-researcher Mark Lemmon of the Institute for Space Sciences in Boulder, Colorado.
Curiosity pointed its Mast Camera, or Mastcam, at the sky about 75 minutes after sunset on June 5, 2020, on the 2,784th Martian day, or Sol, of the mission, the mission report indicates.
“Even the moderately bright stars were not visible when this image of Venus was taken,” Lemmon reported. “Earth also has bright twilights after some major volcanic eruptions.”
NASA’s Rover Curiosity has been on the red planet since 2012. Despite the fact that its mission was planned for only 2 years, the scientists decided to indefinitely extend the stay of the space apparatus on Mars, where it has captured sunsets.
