On July 30, 2020, the National Aeronautics and Space Administration—better known as NASA—launched its latest vehicle into space. The Perseverance rover is on its way to Mars, where it will land in February 2021 to search for signs of ancient life and collect rock and soil samples for future study.
The Perseverance rover is NASA's most recent excursion into the cosmos. Since Oct. 1, 1958, this American institution has contributed much to the dense knowledge of astronomy and space science. Whether it’s through direct space exploration with drones or manned spaceflights, astute observations through a telescope, or satellite images of our world and solar system, NASA pushes the boundaries of aeronautics, aerospace research, and continues to make new inroads with civilian space exploration.
Topics of space and space exploration have always fascinated people. Constellations allowed early sailors to chart their way across oceans and explorers to find their way across giant, unexplored landmasses. The mysteries of space, the heavens, and the expansiveness of our world have inspired religions, literature, and pushed the boundaries of where people believe they fit in the universe. With the advent of rockets and other technologies in the 20th century, public interest in what might be out there beyond our own planet and solar system has only grown.
To celebrate the launch of the Perseverance rover, Stacker compiled a list of real “Jeopardy!” clues about space. The show often acts as a gauge for public interest and curiosity, and its clues have been meticulously catalogued at the , where every show is listed up through early 2020. For this gallery, we’ve expressed each clue along with the “Jeopardy!” category in which it was found, the monetary value of the clue, and the date in which it aired on television. The following slide will then reveal the answer in the form of a question (of course), along with some additional information and trivia about the subject in question.

Answer #11: What is a comet?
Comets are icy, small solar system bodies that warm and release gas upon passing by the sun, producing a visible tail. Russian amateur astronomer Leonid Elenin spotted such a comet in December 2010, and it became more visible during 2011. During that time, it began to disintegrate and was no longer visible by October of that year.

The British ship HMS Endeavor still had influence long after its time, being the name inspiration for two different spacecraft in the 20th century. Apollo 15 had the command and service module CSM-112, which was given the call-sign Endeavor. Also sharing the name was the Space Shuttle Endeavour, which first launched in 1992 and had its final mission in 2011 before its decommissioning.

Answer #14: What is Saturn?
The second-largest planet in the solar system is Saturn, best known for its distinctive ring system. Its rings are mostly made up of ice, dust, and debris. The Cassini spacecraft has since informed astronomers and scientists of the many visual and physical properties of the planet, along with many natural phenomena occurring on it. The Cassini completed its mission shortly after this "Jeopardy!" episode aired, disintegrating as it plunged into Saturn's crushing atmosphere.

Answer #15: What is a meteor?
Meteoroids are generally small rocky or metallic bodies in space, some being formed from debris and most coming from asteroids and comets. Upon entering Earth’s atmosphere, meteors leave a visible trail that leads meteors to be nicknamed “shooting stars.” Meteors originating from the same point and appearing close in time to each other make up meteor showers.

Answer #22: What is Saturn?
Named after the Roman god of wealth and agriculture, Saturn can be easily identified from its distinctive ring system. Its rings are mostly made up of ice, dust, and debris. As the planet itself is mostly made up of gas, it is less dense and lighter than water, and therefore could float in water—should there be a large enough container to fit it in.

Answer #23: What is Halley's Comet?
Named after English astronomer Edmond Halley, Halley’s Comet was the first to be realized and recognized as a periodical comet. It is visible to Earth roughly every 75 or 76 years, roughly once or twice in a lifetime. Author Mark Twain wrote about how his birth was near a passing of Halley’s Comet and accurately predicted that the comet would pass yet again near his death.

Answer #24: What is zero gravity?
Weightlessness, or zero gravity or “zero-G,” is the phenomenon where the sensation of weight is absent. When a gravitational field is zero or near zero, as it is in most of known space, those off-Earth will essentially float. The Neutral Buoyancy Laboratory near the Johnson Space Center features a large pool of water meant to simulate the effects of zero gravity.
