ESA's Hera spacecraft inaugurated use of its science instruments to image the smaller of the planet's two moons, Deimos.
The Red Planet and its tiny moon Deimos were recorded at a very near distance as the asteroid-chasing spacecraft completed a flyby on Wednesday.
The vernal equinox occurs as Mercury stands still in Pisces and several of Jupiter’s moons transit in the sky this week.
"If the moon and a planet are near Castor and Pollux you have an impressive show." From our earthly perspective, the moon and Mars will appear closest to each other at around 8 p.
