Nasa Definition and 304 Threads

Can graphite be used as a catalyst to break down ozone into oxygen without serious oxidization? The applied use for this is to break down ozone at the output of an ionic wind "fan". Similar operation to an ion thruster used by NASA but instead of using stored gasses and propelling them into...

Hello, I am a Chemical Engineering major and a sophomore. When I first got to college I hoped to work in Pharma, but lately I'm becoming more and more interested in working for either the Space industry (SpaceX, NASA, etc) or in the alternative energy field (mainly Nuclear, but also Solar)...

From a "design" viewpoint, a missile (see: Saturn V) has a very high center of gravity and a very small base. It can therefore be expected that the least disruption of the location of the center of gravity relative to the base, will result in the missile to tilt and fall over, especially in...

I did my undergrad in mathematics, and I really enjoyed studying that subject. After graduating, I've been continuing my study in Real Analysis with one of my undergrad professors, and I really feel like I'm blooming into a decent analysis student. This week I'm going to start learning...

Hello all, so I'm just finishing up my basics in undergrad school and am starting to take math and introductory physics classes, and just wanted to clear something up to make sure that I'm not wasting my time. My goal is a PhD in astrophysics. Now I know that in order to get into a good grad...

I'm rather new here so please forgive me if this is answered somewhere else, but I was unable to find it while searching around. For some calculations I'm looking to perform I need to know the geocentric equatorial coordinates of the sun on a given date. However, the only place I know they...

Hi everyone I am a layman at physics am would be very grateful if someone could assist me with a question about propulsion. The question arises from an article I recently saw discussing NASA's testing of a Cannae Drive...

An article at NASA talks about a way to generate thrust without shooting something out the back. http://ntrs.nasa.gov/search.jsp?R=20140006052 From the article: Approximately 30-50 micro-Newtons of thrust were recorded from an electric propulsion test article consisting primarily of a...

NASA confirms ‘impossible’ thruster actually works, could revolutionize space travel http://www.digitaltrends.com/cool-tech/nasa-confirms-impossible-space-drive-actually-works-revolutionize-space-travel/#!btQgmZ Is there any explanation for why this produces a thrust? Does it have to...

Hi, I am a recent high school graduate, and my whole life I have been interested in astronomy. I have always stared in marvel at the night skies and read various books about constellations, etc. When my parents bought a telescope, that only spiked my interest further! I have, also, gained an...

If you guys still haven't heard by now, Earth narrowly missed a solar storm by a week on July 2012. Let's say the storm happened earlier on July 16th, in which we'd be directly hit. How different would our lives be? Where would we be today...

I could not find a thread about this (and I hope I don't start a duplicate one :smile:). I got a mail from a friend today about this: Detection of An Unidentified Emission Line in the Stacked X-ray spectrum of Galaxy Clusters Esra Bulbul, Maxim Markevitch, Adam Foster, Randall K. Smith...

He was a NASA official whose boyhood interest in science fiction and later friendship with Arthur C. Clarke led to his becoming Stanley Kubrick's chief technical and scientific advisor during the production of "2001: A Space Odyssey." http://www.nytimes.com/2014/07/14/us/14ordway.html?_r=0

Hello everyone, I have a question regarding aerospace technology civil engineering. What are the chances that you get to work with companies such as NASA and SpaceX? In case it is low, what do you do otherwise with the degree you have been working on? I might want to pursue a degree in...

Homework Statement As part of a NASA experiment, golfer Tiger Woods drives a golf ball on the moon, where g = 1.60 m/s2. He ‘launches’ a golf ball with a speed of 285 km/h, at an angle of 42o with the horizontal. What horizontal distance will his drive travel before landing back on the...

I know some folks may get tired of questions about the finite/infinite scope of the universe. Sorry for that. But as you know, many concepts are hard to wrap one's head around. Let me make my question as clear as possible from the outset: -I am NOT asking whether the universe is infinite or...

http://svs.gsfc.nasa.gov/vis/a010000/a011500/a011537/ This is so confusing. If light travels at the speed of light, c, then how can it take 40,000 year to get out from the sun? Photons undergo fusion? hahaha. I never knew that

I'm only a freshman in college, but I am always thinking about the future. I plan to earn my Bachelor's in Physics or Astrophysics, and then continue onto graduate school. I'm at Penn State University, so I plan to stay here for all of my degrees unless a better, more valuable opportunity...

I was going to do a double major at penn state with aerospace engineering and either physics or astronomy and astrophysics. Which one would better help me get a job at NASA? physics or astronomy and astrophysics

Homework Statement What is the maximum time and the minimum time it takes for communication from the space shuttle to reach the Director of NASA who is seated 20 meters away from the communication radio at Mission Control at the Johnson Space Center in Houston, Texas. You may assume that room...

Ok. Let's start from the beginning I guess... I am 14 years old, turning 15 next month. I'm a freshman in high school. I love math and science. Ever since 5th grade I have been 2 grades ahead in math. I'm taking Alg. 2 right now. I do consider myself very smart. I love physics and astronomy...

If I were to take published data from public NASA reports and printed Journal articles and sell the data (after doing some processing to it), would that be grounds for a lawsuit against me? I'm wouldn't be selling the article itself, but taking important data from articles over a span of 40...

Hello everyone! My name is Christian and I'm in 8th grade (2 weeks until schools out!) Ever since 5th grade I've loved astronomy, and its been just recently that I've actually began to think about my future. When I was in 5th grade I was already taking 7th grade math so I would consider my self...

I will get to pick some non ME electives corresponding to a semesters coursework, and my interests lies in these fields. Which will be more useful? I know the former is more physics focused and the other is more hardcore maths. I want to work for NASA after college, building or designing...

Hello Everyone, I am new to this forum and am actually just curious to hear if you can help me with something? The reason I joined this forum is because I am interested in finding out about being able to get some of that material, which NASA uses for its space shuttles...the heat-absorbing...

Is it possible to be a theoretical physics and astrophysicist and still do independent research while working for NASA?

Via the Uncertain Principles blog, the NYT reports: Although the Obama administration has made effort to make science central in policy, it has so far struggled with what long-term strategy to take with NASA. It has yet to name a NASA administrator; and during the transition engaged in a...

Hi, I am wondering why is it so important to put people on Mars? It is very dangerous and Nasa does not have the technology to do this safely without endangering lives. Why can't they wait for proper technology to do it correctly? In my opinion you need similar to following; 1) ability to...

I think this is too damned funny! :smile: http://www.google.com/hostednews/ap/article/ALeqM5hVxsBGs7scxZSkcCE1cL2B4BlECAD974D8800

Very cool image. Does anyone know, is anything in the information we got from this so far at all surprising? Is it likely we will learn anything about gamma ray bursts from this or is more information

Nasa is facing more problems with it's Shuttle replacement. following Ares-I being too small to lift anything the Ares-V looks like it is too heavy for the road to the launchpad. http://www.flightglobal.com/articles/2008/08/21/314931/nasa-faces-budget-busting-crawlerway-rebuild-for-ares-v.html...

While on NASA Glen research website this morning I came across their page about warp drive. In the first few lines they say they are not sure if faster than light travel is possible. Not sure? So does that mean NASA thinks it may not be impossible to travel fater than light either then. I was...

A NASA satellite has uncovered evidence that a sea of neutrinos, almost weightless elementary particles that zip around at nearly the speed of light, permeates the universe. The discovery is part of a treasure trove of findings gleaned from data collected by the Wilkinson Anisotropy Probe...

I want to work for NASA. As a physics major, what is the best way to get a job as a physicist at NASA?

I don't know much about Nasa or their shuttles but i am wondering once they get into space can't they go as fast as they want, or is there something i don't know about.

Not sure what to make of this one. Its a very popular recent story on various websites. obviously its a quite far fetched sounding story, but it is being made by people who acually worked at NASA. The fact there is a book being written on this does not help his cause either. But that is no...
