[Answer] Olympus Mons, the largest volcano in the solar system, was found where?

Step 1 : Introduction to the question "Olympus Mons, the largest volcano in the solar system, was found where?"

...NASA’s robotic space probe Mariner 9 has made some amazing contributions to space discoveries. Among the most interesting was its confirmation of Olympus Mons in 1971. The probe mapped 85% of the Martian surface, sending back over 7,000 of the Red Planet’s landscape, including Olympus Mons, Valles Marineris (one of the largest canyons in the solar system), and Phobos and Deimos, the two small moons of Mars. Olympus Mons is a shield volcano that stands around 72,000 feet high (over twice the height of Everest) and is as wide as the state of Arizona.

[Answer] Who first described and published 48 ancient constellations?

Step 1 : Introduction to the question "Who first described and published 48 ancient constellations?"

...Ancient civilizations across the world have studied and mapped the stars for centuries. In the second century C.E., Roman astronomer Claudius Ptolemy cataloged many of these ideas in the “Almagest,” an influential astronomy text that described 48 ancient constellations, including the traditional zodiac signs. Ptolemy collected these constellations from various sources including Mesopotamia, Babylon, Egypt, and Greece. Along with the constellations, he listed apparent motions of the stars and planetary paths. The "Almagest" served as a guide for Islamic and European astronomers until the beginning of the 17th century. Astronomers have been adding to Ptolemy’s original list for centuries, leading to the 88 recognized constellations of today.

[Answer] First discovered in 1831, what is Jupiter’s “Great Red Spot”?

Step 1 : Introduction to the question "First discovered in 1831, what is Jupiter’s “Great Red Spot”?"

...Amateur astronomer Samuel Heinrich Schwabe first observed the giant storm on the surface of Jupiter nearly 200 years ago. Twice the size of Earth, the storm is essentially a massive hurricane, whirling around Jupiter’s southern hemisphere with wind speeds up to 425 mph (twice as strong as an EF5 tornado). Jupiter doesn’t have a solid surface, so there is nowhere for the storm to “break” as a hurricane does on Earth, which scientists believe is partially to blame for the ongoing storm.

[Answer] What major discovery did Galileo make with his telescope in 1610?

Step 1 : Introduction to the question "What major discovery did Galileo make with his telescope in 1610?"

...Italian astronomer Galileo Galilei was an early pioneer of space exploration. Though all he had was a telescope, he made some of astronomy’s most important early discoveries. He discovered the four largest moons of Jupiter (Io, Europa, Ganymede, and Callisto) which are now referred to as the Galilean moons. Galileo discovered that the Milky Way was made up of individual stars, and he was the first to see lunar craters, sunspots, the phases of Venus, and Saturn’s rings. Thanks to his discoveries, the theory that everything in our solar system revolves around the sun and not the Earth grew in popularity.

[Answer] What was the goal of NASA’s Apollo Program?

Step 1 : Introduction to the question "What was the goal of NASA’s Apollo Program?"

...One of NASA’s most famous space race-era programs, Apollo, was active from 1969 to 1972, and was the first program in the world to land humans on the moon. During its course, Apollo landed six flights on the moon and supported 12 different astronauts’ moonwalks. While these moonwalks typically stole the show, the program also provided groundbreaking research, including detailed studies of the lunar surface, moon rock samples that were brought back to Earth, and the development of lunar rovers.

[Answer] What was the first satellite to launch, starting the space race?

Step 1 : Introduction to the question "What was the first satellite to launch, starting the space race?"

...Launched by the Soviet Union on October 4, 1957, Sputnik I was the first human-made object to be sent into space. “Sputnik” originally meant “fellow traveler” but now means “satellite” in modern Russian language. Sputnik I provided crucial data for future space travel, including how to place things into orbit, the density of Earth’s atmosphere, orbital tracking, and aspects of radio waves and pressurization in the atmosphere. The basketball-size satellite orbited for three weeks until its batteries died, and it eventually burned up in the atmosphere a few months later.
