Looking up at the vast night sky, the wonder and excitement of space captivates many people. We wonder what is out there, or who is out there? The Pixar animated film Lifted takes our curiosity and puts it on the big screen. The story focuses on a little teen alien named Stu, as he tries to pass his human abduction exam, graded by Mr. B. Stu attempts to abduct a rural farmer named Ernie. Stu, being an overconfident teen, hilariously messes up the entire abduction, amazingly not waking up Ernie.…

When the shadow of one celestial body, the Moon or another planet in our solar system for example, moves in front of another’s shadow an eclipse takes place. There are several types of eclipses, which all depend on the shadow that is involved. There are three different types of shadows, the umbra, penumbra, and antumbra. Each type of shadow varies by its darkness and position within the full shadow. The umbra is the dark center, the antumbra is the light center, and the penumbra is the light…

“Mystery creates wonder and wonder is the basis of man’s desire to understand.” - Neil Armstrong, the man who first set his foot on the moon, then a distant object and a source of awe; and it is in this quest of surmounting the unconquered and taming the wild which denotes man’s insatiate desire to understand Nature. Evolution has been the fundamental reason for progress of life on earth and the eclectic strategies employed by Mother Nature in the eternal perpetuation of the process are simply…

discover the small planet that would be known as Pluto. Since Pluto was much small than Neptune and Uranus, the question of whether it’s mass was enough to cause the wobbles in Uranus and Neptune’s orbit. Twenty-eight years later, when Pluto’s biggest moon, Charon, was discovered they were able to conclude that both Pluto and Charon’s mass combined was what was causing the wobbles in Uranus’s and Neptune’s…

“We’ve grown used to the idea of space, and perhaps we forget that we’ve only just begun. We’re still pioneers.” On January 28, 1986, President Ronald Reagan addressed the Nation’s fears and sorrows after the explosion of the NASA Space Shuttle, the Challenger. Almost a half-century ago, man began to look past the stars and into the cosmos and planets beyond Earth. The brilliant mind behind the curtain, Wernher von Braun, “The Father of Modern Rockets”, sparked the curiosity and imagination of…

of America and the USSR were in competition with one another to see who could conquer spaceflight capability. The Space race included efforts to launch artificial satellites, unmanned space probes, sending humans into space and setting foot on the moon. The First part of the race was to launch a successful artificial satellite. The USSR beat the United States to this with the successful launch of Sputnik 1 on October 4 1957. The launch was a shock to all Americans which put them under a lot of…

years old, I was awestruck by the universe on the big movie screen. Star Wars had me hooked; I NEEDED a telescope so I could learn about what lies beyond the sky I see at night. My parents bought the telescope I yearned for and helped me look at the moon on clear nights. Together we watched shuttle launches on television and read about expeditions online. A few years later, they took me to see a shuttle launch at Cape Canaveral. We arrived just before launch because the visitor’s center was…

Without the newly developed methods and designs to reach space with the Saturn payload, the Apollo program won't be a success. In order to lift the massive payload required to reach the moon, the Saturn V rocket required millions pound of thrust. The First stage comprised of five-engine cluster for the 7.5 million pounds of thrust using liquid oxygen and kerosene fuel. The Second stage had five J-2 engines and the third with one J-2 engine all using hydrogen-oxygen fuel. Without the development…
