Mars Space Exploration This Day in Science, Technology, Astronomy, and Space Exploration History

The first soft Mars landing was performed on December 2, 1971

On December 2, 1971, Soviet Union’s Mars 3 robotic space probe performed the first soft Mars landing. But, just 110 seconds after the landing, and 20 seconds after the transmissions has begun, it failed and transmitted just a gray image with no details. Although having no scientific value, this was the first transmission ever from the surface of Mars.

Mariner 9 became the first spacecraft to maintain an orbit around another planet [Mars] on November 14, 1971

On November 9, 1971, NASA’s Mariner 9 spacecraft entered Mars orbit and became the first spacecraft to maintain an orbit around another planet than Earth. Mariner 9 beat Soviet Union’s Mars 2 by 13 days despite being launched 11 days later than its Soviet counterpart.

In about 11 months, the orbiter mapped 85% of the Martian surface and sent back more than 7,000 pictures, including images of Olympus Mons (the highest mountain in the Solar System), Valles Marineris, and two natural satellites of Mars, Phobos, and Deimos.

Super blue blood moon explained [What is it and how Super blue blood moon occurs]

The Super blue blood moon is a rare celestial phenomenon. It is made up of three coinciding events. A supermoon is a full moon when our satellite is at its closest (hence it appears bigger in the sky). A blue moon refers to an “extra” full moon, whereas a year that usually has 12 full moons has 13 instead. The “blue moon” reference is applied to the third full moon in a season with four full moons.

In addition to these two phenomena, during a lunar eclipse, when the moon passes through Earth’s extended shadow, it looks reddish, and that is a “blood moon”. When all those three phenomena occur at the same time, it’s called a Super blue blood moon.

Unfortunately, this trend of severe hurricanes will likely continue due to climate change unless action is taken.

World’s largest living cat: Hercules, the liger

Ligers are the largest cats on Earth. A liger can be more than 900 pounds (about 408 kg) in weight and 12 feet (about 3.65 meters) long, weighing almost 100 times more than house cats and almost twice as much as either Panthera tigris (tiger) or Panthera leo (lion).

The liger, the largest of all known extant felines, is a hybrid cross between a male lion and a female tiger.
