Sunset: as seen from Earth and from Mars. To wit:

For comparison, two images of our common star were taken at sunset, one from Earth and one from Mars. These images were scaled to have same angular width and featured here side-by-side. A quick inspection will reveal that the Sun appears slightly smaller from Mars than from Earth. This makes sense since Mars is 50% further from the Sun than Earth. More striking, perhaps, is that the Martian sunset is noticeably bluer near the Sun than the typically orange colours near the setting Sun from Earth. The reason for the blue hues from Mars is not fully understood, but thought to be related to forward scattering properties of Martian dust. The terrestrial sunset was taken in 2012 March from Marseille, France, while the Martian sunset was captured in 2015 by NASA‘s robotic Curiosity rover from Gale crater on Mars. Last week a new rover and a helicopter — onboard Mars 2020launched for Mars.

A rocket trail (captured from a small plane) against the morning sky above Florida’s ‘Space Coast’ yesterday. To wit:

It was July’s third launch of a mission from planet Earth bound for Mars. The Atlas V rocket left Cape Canaveral Air Force Station from Space Launch Complex 41 at 7:50am EDT carrying NASA’s Mars 2020 Perseverance Rover. The car-sized Perseverance is headed for a landing at Jezero Crater on the Red Planet in February 2021. On board the sophisticated rover is the Ingenuity Mars Helicopter.

A 360 degree panorama of Perseverance Valley on Mars taken last year by the Opportunity Rover. To wit:

The scene is composed of 354 individual images recorded through 3 different colour filters by the rover’s panoramic camera from May 13 through June 10, 2018. A few frames remain in black and white at the lower left though. Those were obtained through only one filter just before a dust storm engulfed Mars in June 2018, ultimately ending the solar-powered rover’s trailblazing 15 year mission. Just right of center, the annotation identifies Opportunity’s entry point to Perseverance Valley along the Endeavor crater’s western rim. The rover’s tracks begin there, extending from over the horizon toward the far right and its final resting spot on the Red Planet.

Every month, the Mars Reconnaissance Orbiter (MRO), launched in 2005, sends images back to Earth.

A recent batch of more than 1,000 photographs coincided with the Martian equinox when the sun shone directly onto the planet’s equator, revealing clear views of a surprisingly diverse, multicoloured terrain normally shrouded in darkness.
