In the late 1950’s and early 1960’s the US was in the midst of the cold war. At that point, the American space program had fallen far behind Soviet rocket technology. Desperate to upstage the Soviets, the US began to pour funding into seemingly crazy technological research. One of these projects being Project Orion. In … Continue reading Project Orion: Blasting Off to the Stars → Continue reading → Continue reading
All satellites in low Earth orbit will eventual fall victim to orbital decay. Over time, a satellite will lose orbital energy through drag caused by friction with the atmosphere. Many large satellites, such as the ISS, employ small thrust to counter out the effects of orbital decay. However, as shown by China’s space station, … Continue reading Orbital Decay and China’s Space Station → Continue reading → Continue reading
While the search for life on Mars is still ongoing, another planet may be the first world to where extraterrestrial life is found: Europa. Europa is a rocky moon of Jupiter, and it is known to have vast oceans of liquid water under thick sheets of water ice. Given it’s substantial size, it … Continue reading Europa And The Search For Life → Continue reading → Continue reading
The Telegraph As time progresses, the sun will eventual expand, engulfing the rocky worlds of our solar system. With Earth vaporized, evidence of human life on Earth will disappear with the planet. Long after Earth’s demise the Voyager probes will continue to roam the cosmos, caring evidence of human life, waiting to be discovered … Continue reading Voyager; Humanity’s Furthest Trace → Continue reading → Continue reading
Last Tuesday, SpaceX successfully launched the Falcon Heavy rocket. Excluding the Saturn 5 rocket, this is the most powerful rocket system ever developed. The goal of the launch was test the Falcon Heavy’s ability to deliver a payload to orbit and land safely to earth. Then rocket launch commenced at 2:45 PM CST on Tuesday, … Continue reading SpaceX Falcon Heavy Launch → Continue reading → Continue reading
Up until recently, the only way we have been able to gather information about stars, galaxies, and the universe around us has been through the study of light. However, as of the last few years, the discovery of gravitational waves provides a new method of collecting information about the universe. Although gravitational waves were first … Continue reading Gravitational Waves → Continue reading → Continue reading
Sir Isaac Newton lived from January 4, 1643 to March 31, 1727. He is commonly hailed as the father of classical mechanics and one of the most influential scientists and mathematicians of all time. Beyond developing calculus, which serves as the infrastructure for modern astronomy, he discovered the fundamental laws that govern bodies of terrestrial and astronomical … Continue reading Newton: the Father of Modern Physics and Astronomy → Continue reading → Continue reading
The Universe is an unbelievably vast entity. Earth’s radius is about 6.4*106 meters. In overwhelming contrast to this, the radius of the observable universe is approximately 4.4*1026 meters. That is a difference of 20 orders of magnitude. If the earth’s radius, and the universe as a whole, was scaled down such that the earth was the size of … Continue reading Earth Measured Relative to the Cosmic Scale → Continue reading → Continue reading
