Explanation: In this recent HiRISE view from the Mars Reconnaissance Orbiter, the little green dot indicated on the surface of the big Red Planet is the Perseverance Mars rover. Recorded on June 13, the car-sized, six-wheeled robot was imaged a day before completing a Martian marathon, traveling a total distance of 26.218 miles (42.195 kilometers) since it began exploring the surface of Mars. That equivalent marathon distance was achieved by Perseverance on its mission sol (Martian day) 1,890, after about 5 Earth years and 4 Earth months of driving. Perseverance is continuing to hunt for biosignatures. In the HiRISE image, the Mars rover's tracks can be seen leading to its location in an area west of its landing site in Jezero crater near an ancient river delta.

Mel Brooks is turning 100 years old tomorrow. Everyone knows and loves his comedy. Not everyone knows he served as a US Army combat engineer in WWII and was in the Battle of the Bulge.

Happiest of birthdays to the GOAT of mocking Nazis. ❤️

With its 39 m primary mirror, our Extremely Large Telescope (ELT) will deliver incredibly sharp images of the Universe.

How? Enter the M4, the fourth mirror in the ELT's optical path. This extremely thin levitating mirror will deform up to 1000 times per second, counteracting atmospheric turbulence in real time and yielding crisp images of astronomical objects.
