OSIRIS-REx Exciting Mission to the Asteroid Bennu

The movie Don't Look Up was interesting if not weird. However you feel about the movie, its premise of a comet is coming to destroy Earth is low, but not impossible. That's one of the main reasons NASA launched the OSIRIS-REx Mission to explore the asteroid Bennu. It's not a comet, however, the asteroid is close enough to cause damage. "OSIRIS-REx" is an acronym that stands for Origins, Spectral Interpretation, Resource Identification, Security, and Regolith Explorer. The OSIRIS-REx mission sent a space probe to Bennu back in December 2018 to "touch down" on the near-Earth asteroid Bennu some 200 million miles away to collect a sample and return to Earth in 2023. Yes, 200 million miles is NEAR Earth. The $1.16 billion OSIRIS-REx mission will be the first American spacecraft to return samples from an asteroid if the mission is successful. Bennu is one of the millions of asteroids in our…

The Polarizing Reasons Pluto is Not a Planet Anymore

Pluto was previously considered a planet since its discovery in 1930 by Clyde Tombaugh. Pluto had little resistance to its classification as the ninth planet upon its discovery.This may have been a slight case of confirmation bias since the presence of a "ninth planet" or "planet X" was hypothesized by Percival Lowell. Lowell believed that the apparent discrepancies of Uranus were the causation of another planet beyond Neptune.Pluto was within only 6 degrees of the predicted location of the ninth planet predicted by Lowell. However, Lowell predicted that this planet would be around 6.6 the mass of Earth.As telescopes improved, we were able to learn more about Pluto. In 1950, Gerard Kuiper observed Pluto as a spherical world using a 200-inch telescope at Mount Palomar. Kuiper estimated that Pluto's diameter was around 5,900 kilometers.In 1965, Pluto passed near a star allowing astronomers to conclude that Pluto was a small body. As…

Why Saturn’s Moon Mimas is so Awesome

Mimas is Saturn's seventh moon and one of the most mysterious objects in the Solar System. One would think that Mimas inspired the Death Star from the 1977 film Star Wars Episode IV: A New Hope, but the movie was made three years before the crater's discovery by Pioneer 11 in 1979.Voyager 1, Voyager 2, the Cassini probe in 2010 have visited Mimas since its discovery. Mimas, however, did make a pop culture appearance in Star Trek: The Next Generation, Season 5, Episode 19, The First Duty. The episode featured the moon when Wesley Crusher was beamed to Mimas in an emergency after some suspect piloting Wes and pals, but that's another issue."Mimas" was derived from the "Giants" in Greek mythology. But don't confuse the Giants with the Titans. Both groups have the same mother and father, Gaia and Uranus. Although they had the same parents, how the Giants came into this world is just a tad bit…
