IMAGES: NASA’s Mars InSight Lander Captures Sunrise and Sunset on Mars

(NASA) – NASA’s InSight lander captured a series of sunrise and sunset images.

A camera on the spacecraft’s robotic arm snapped the photos on April 24 and 25, the 145th Martian day, or sol, of the mission.

In local Mars time, the shots were taken starting around 5:30 a.m. and then again starting around 6:30 p.m. As a bonus, a camera under the lander’s deck also caught clouds drifting across the Martian sky at sunset.

These images are available as both “raw” and color-corrected versions. It’s easier to see some details in the raw versions, but the latter more accurately show the images as the human eye would see them. Much farther from Mars than it is from Earth, the Sun appears only about two-thirds the size that it does when viewed from Earth.

This is actually the second time InSight has captured these daily events.

The camera took practice shots on March 2 and 10.

“It’s been a tradition for Mars missions to capture sunrises and sunsets,” said Justin Maki, InSight science team co-investigator and imaging lead at NASA’s Jet Propulsion Laboratory in Pasadena, California.

“With many of our primary imaging tasks complete, we decided to capture the sunrise and sunset as seen from another world.”

NASA’s InSight used its Instrument Context Camera (ICC) beneath the lander’s deck to image these drifting clouds at sunset. This series of images was taken on April 25, 2019, the 145th Martian day, or sol, of the mission, starting at around 6:30 p.m. Mars local time. (NASA Image)

The first mission to send back such images was the Viking 1 lander, which captured a sunset on Aug. 21, 1976; Viking 2 captured a sunrise on June 14, 1978.

Since then, both sunrises and sunsets have been recorded by the Spirit, Opportunity and Curiosity rovers, among other missions.
