The organization of the command system in Operation Oluja took place via two levels of command relations: full command deriving from legal authority and operational command or operational control as delegated authority of command of assigned forces. Full command was executed according to the organizational structure of the armed forces, all deriving from legal authority of the appointed commanders. Operational command or operational control as delegated authority of command of assigned units was…

Joshua Connolly 08 August 2015 NCAS2015FALL Evolvable Mars Campaign Essay Question # 4 The question of how to effectively plan a mission to Mars is multi-faceted. To convey the idea of the best mission, every portion of the mission must be discussed. The spacecraft must be designed to meet all mission and safety specifications. The testing must recreate possible scenarios encountered for the duration of the mission. The actual spaceflight plan must account for every action the mission is to take…

white dwarf is created after a smaller star dies. The only way for a star to become a black hole is if the star was 10-15 times more massive than the sun. The diameter of a black hole is approximately the diameter of New York City. A black hole’s gravitational pull is so strong that not even light can escape. The idea of black holes existed for centuries, but the name black hole was given to them in 1967 by a physicist named John Wheeler. Scientists can’t study black holes via telescopes that…

Black holes are thought to be born from stars or other massive objects that collapse from their own gravity to form an object whose density is infinite. Once all the dying stars’ fuel for nuclear burning has run out, what’s life is the core; In a black hole, otherwise known as a singularity. The space surrounding the singularity…

CYGNUS One of the most prominent constellations in the night sky, and one of the most involved and eventful regions of space, the Cygnus constellation and its surrounds are fascinating, and a worthwhile talking point for many a topic. Occupying an area of 804 square degrees, Cygnus is the 16th largest constellation in the night sky; it lies in the fourth quadrant of the northern hemisphere, with right ascension at 20.62, and declination at +42.03: in other words, if you were in the northern…

Recent revelations in the news over NASA finding “liquid” water on Mars has gotten many people excited about the possibility of sending humans to live on the planet, without much insight into the actual reasons why that idea is still not currently feasible. A planet must have much more than just water in order to be a habitable place, and these factors are often overlooked, in fact the same factors affecting the water supply on Mars are also the factors that factors behind the other reasons it…

J. Robert Oppenheimer had a very interesting life that undoubtedly influence his works in science. He was born on April 22, 1904 in New York City, New York. The Oppenheimers were Ashkenazi Jews. In his childhood, J. Robert Oppenheimer moved to Manhattan. Early on, Oppenheimer attended Alcuin Preparatory School. However, in 1911, he switched and began attending the Ethical Culture Fieldston School. His family was a part of the Ethical Culture Society. The Ethical Culture Society was an outgrowth…

Messier 81 also known as NGC 3031 or Bode's Galaxy) is a spiral galaxy about 12 million light-years away in the constellation Ursa Major. Due to its proximity to Earth large size and active galactic nucleus] or supermassive black hole), Messier 81 has been studied extensively by professional astronomers. The galaxy's large size and relatively high brightness also make it a popular target for amateur astronomer. Messier 81 was first discovered by Johann Elert Bode in 1774.Consequently, the galaxy…

simulations have shown us an estimate of what would happen amidst a merging such as this. The Hubble Space Telescope; in measuring the motions of the Andromeda galaxy, now tells us that Andromeda is falling toward the Milky Way galaxy due to the gravitational pull of both galaxies. (6). Because the collision is said to be head-on, many stars will most likely be thrown into different orbits as an effect of the new galactic center. Andromeda is currently moving toward the Milky Way at about…

Isaac Newton was an English natural philosopher, scientist, mathematician, chemist and physics that influence modern studies and society. His studies and discoveries laid a foundation to many present-day science, math and technology. Newton have a rough childhood, dealing with neglection that left him emotionally unstable. With that said, Newton was a brilliant person that mark his footstep in the field of Science and Math. Isaac Newton was prematurely born on Christmas day in 1642 in…
