Escape velocity

radiation from its planet, Jupiter, because of its lack of an atmosphere. Its extreme temperature can make it even harder to colonize the surface. The temperatures can freeze liquid water in a matter of seconds. Low gravity can let astronauts reach escape velocity, which can cause them to go into space. So why haven’t we decided to travel to Europa until now? With freezing temperatures ranging around 102 Kelvin, it’s no wonder Europa is covered in ice. To avoid the frigid temperatures, the…

Dillard understands there is a world outside of Pittsburg, and outside of her family and their beliefs. “I was gaining momentum…I was approaching escape velocity.” (254). Dillard wants to explore the world, the same curiosity that burned within her when she was obsessed with the amoeba. She is aware that for the time being her immediate future is planned out, but she decides to not to let it ruin her outlook…

The Star Wars Series is a saga of films loved by just about every person in the United States. From middle-aged Sci-Fi nerds to middle school jocks, you’d be hard pressed to find somebody that “just didn’t get the hype.” The first Star Wars film, Star Wars Episode IV: A New Hope, was released in 1977 and the last film of the series (so far), Star Wars Episode III: Revenge of the Sith, was released in 2005. Though the original movie was a pop culture phenomenon and has changed film forever, the…

I’ve been on this ship with the Hesperis crew for two months now. We are somewhere in the middle of space between Earth and Venus. Travelling to Venus takes about 5 months, which means I still have three months of living (a very generous term for this situation in my opinion) in a 300 ft3 room with three other people [1, 2]. Trust me it’s not fun. It is difficult enough to live in a cramped living area by myself. The most common topic when discussing human space travel is the effects radiation…

What are Dark Matter and Dark Energy? Introduction: To start with, Dark Matter is invisible material that permeates the galaxies. It exerts a gravitational influence on the stars causing them to deviate from Newton’s and Kepler’s laws. Dark Matter also affects members of a group of galaxies. The nature and composition of the Dark Matter are unknown. In space there is a lot of totally empty space, the vacuum, which contains energy. This energy is variously called Dark Energy and also may be…

depolarization event occurs which causes the electrical potential to drop. If it reaches a threshold of (-55 mV) the fast V-gated Sodium channels activate at the axon hillock. This brings the membrane potential to +30 mV in a quick burst as the Na+ ions escape and the sodium channels inactivate. At this point the relatively slower V-gated K+ channels activate and the movement of K+ bring the membrane potential to -90 mV thus hyperpolarizing it. The V-gated K+ channel eventually closes and the…

many types of non-Newtonian fluids, as they are defined to be something that fails to obey a specific (particular) property i.e., most fluids with long molecular chains can react in a non-Newtonian way. The constant of proportionality between the velocity gradient and the viscous stress tensor is known as the…

David Wen 0277- Theory of Knowledge Sir Winston Churchill Secondary School B. Patton 21-01-2015 Reasoning with Imagination topic #1: Compare the roles played by reason and imagination in at least two areas of knowledge To what extent does reason require imagination? In the field of epistemology, the roles played by reason versus those played by imagination have been controversial. Reasoning is the action of thinking about something in a logical, sensible way whereas imagination is the faculty…

pounds, whereas the Apollo lander weighed about 36,200 pounds. That’s only 5% of the entire mass of an Atlas V rocket. So all in all, you can launch something that weighs 36,200 pounds, with 0.1% of the required force and fuel to reach lunar escape velocity. This means you can simply launch a payload from the surface of the Moon, you would no longer require a rocket to deliver…

Wall-e is a new, dare say one of the best upcoming roller coasters and it is based off of the sensational movie Wall-e made by Disney’s Pixar. In the movie, the plot takes place in 2805 where humans have abandoned Earth on the account of it was not in the ideal shape for humankind to live in. Therefore, humans left robots to clean up the mess they had made where after some time, the Earth became habitable once more. Mankind had been sending extraterrestrial vegetation evaluators or EVE to Earth…
