With three probes on their way to Mars, NASA’s Curiosity rover will celebrate its eighth year on Mars 6 August as it continues to explore the lower regions of Mount Sharp in Gale Crater. This frame from a panorama captured on 13 October 2019 shows Mount Sharp in morning sunlight.

Curiosity landed on Mars in 2012 and has collected data showing the environment in Gale Crater, at least, was habitable in the distant past. NASA’s Perseverance rover will land in Jezero Crater next February to search for signs of past microbial life. The Hope orbiter, built by the United Arab Emirates and currently on its way to Mars, will slip into orbit that same month as will China’s Tianwen-1 probe. The Chinese mission features an orbiter and a rover, which is expected to descend to the surface a few months after arrival.
If clear skies persist, observers in the UK can view four naked-eye planets between now and the end of the month. Brightest planet Venus is visible low in the west some 45 minutes after sunset, while the waxing Moon is your celestial pointer to Jupiter, Saturn and Mars between 21 and 28 July at midnight.
