Nasa Definition and 304 Threads

I recall that a few years ago NASA awarded a contract for a "new" kind of propulsion, the details of which I have forgotten, and I would like to find any old news announcement about this from about the time of this award. My memory includes that the NASA contract to study this "new" method of...

NASA did a study how to investigate the surface of Europa. It is separate from the Europa Multiple-Flyby Mission, which has a small lander as well, but only with a small budget. Confusingly, the same artist's impressions are used for both. There is also ESA's Jupiter Icy Moons Explorer...

There has been a lot of controversy surrounding the EmDrive and it supposedly being a reaction-less drive Many have pointed out that this goes against the conservation of momentum I have seen videos of a couple people dismissing the notion and outlining the apparent issues with the physics I am...

It is hard not to hear that NASA has just published paper claiming confirmation of "impossible drive" - closed resonant chamber: http://arc.aiaa.org/doi/full/10.2514/1.B36120 http://www.sciencealert.com/it-s-official-nasa-s-peer-reviewed-em-drive-paper-has-finally-been-published...

for those interested: http://www.sciencealert.com/nasa-s-holding-a-press-conference-about-surprising-activity-on-europa-on-monday Any speculations as to what they will announce? I was thinking plumes like on Enceladus but then I realized they've already been seen on Europa. So my guess it'll be...

"Are you currently serving (or have previously served) as PI, PD, Co-PI, or Co-PD on any federally funded project?" Hey, y'all! I'm applying for a grad school fellowship, and I'm not sure how to answer this question. Would this include being an NSF REU fellow, or not? I believe not, but I want...

Its always been a dream of mine to work for NASA but so many people (whether they've worked for them or not), have said that it takes so long to work towards and it isn't even that satisfying of a job...

For how long will we still be able to communicate with the amazing Voyager 1?

Hi, just came across a video on CNN showing how to make water behave like it would in space: <link to video deleted> My question about that video is: what height do i need to get a free fall time of 10 sec? best regards

Getting into NASA would be my greatest achievement. Presently, I am a chemistry graduating student. Do I need to study something to get qualified there? (I am not a US citizen)

Caltech astronomers have published evidence recently of a possible new planet. You can read about the full story here. I have also submitted a video on what NASA says about it. What do you guys think? I think it'd be cool to see a new ninth planet come out. Also, I wonder what it will be named...

Does JWST has any significance in fundamental physics research? What kind of questions would we get answers to?

So I always see in the news that the curiosity rover or some NASA study of previous data discovered evidence of water like its actually news. Wasn't it shown a decade ago that there is conclusive evidence that lots of water existed on mars? I don't get why they're still spending so much time...

This is really amazing. Can you imagine just how long these jets are? image compliments of http://www.usatoday.com/story/tech/sciencefair/2015/12/17/nasa-spies-lightsaber-space/77478854/

http://www.iflscience.com/space/nasa-announce-key-findings-fate-martian-atmosphere I think 'huge' may be a gross overstatement. I think they're going to announce how recently Mars' atmo was thick and how soon it will be gone, and that's about it.

Hi everyone! I'm at the end of the second semester in an mechanical engineering undergraduate course. I love spacecraft s, rocketry, aircraft and all that aerospace stuff, so I'm decided that, so long I finish my undergraduate, I'm going to pursue a major in aerospace (maybe something related...

Hi everyone I am currently a freshman in college planning on applying to the School of Engineering next fall. I want to be an Astronautical Engineer but my school doesn't even have Aerospace so I was planning on doing Mechanical. I would like to work for NASA as an Astronaut but I would also be...

That's the title of the NASA press release (I added the date). 8 a.m. PDT = 3 p.m. UCT = 5 p.m. CEST (Central European Summer Time) The panel includes an expert for the HiRISE experiment, a high-resolution telescope in Mars orbit. Whatever they have, apparently images of some area are highly...

Hi! So I'm a college student and I was looking at trying to get together a group to compete in NASA's student launch initiative. However I don't really know anything about rocketry and don't know where to start. I'm currently studying mechanical engineering and planning on emphasizing in...

I am not a US national but I'm really interested to graduate in Astronomy and work with NASA. So I've heard a lot of rumours that non US nationals cannot get job in NASA. Is it true.? If yes then which of the other space agencies offer job to outsiders (someone not national of that country)

So, I did a little searching around on these forums before I posted this, and I do see lots of threads about working for NASA but not something about my specific situation. I'm currently attending a college working on my AA. After that, I'm probably going to transfer to a University, where I'll...

I am very interested in the Astronautical area of science; however I am still in high school so I don't get a lot of time to read up on the latest news about this future mission. This is why I am eager to be filled in on the latest news about the mission. I am looking to know about the...

I am for second year of dental & is interested in working in NASA . so please help me ?

From what I understand, our Hubble's sphere is just relative to Earth and has a diameter of 93 billion light years putting the edge of the observable universe at 46-47 billion light years away. So every object in space will essentially have it's own Hubble's sphere and objects near the edge of...

http://www.nasa.gov/keplerbriefing0723 As I type this, NASA is announcing discovery of a new planet Kepler 452b that is - small and (probably) rocky like Earth - orbits a G2 star - is in the star's habitable zone This is the first candidate that meets all three criteria. (Most Earth-twins so...

Can someone please give a step by step explanation of an orbital rendezvous by a spacecraft for a target that is orbiting the body it launched from? And if possible, can you explain how mission control is involved and what part computers play? When the RCS is active is it changing the...

I think I am going crazy because i could have sworn i remember a press conference with NASA displaying rocks from Mars with worm fossils in them. and this was about 12-10 years ago. Any reference to this on the internet seems to have been wiped out...Am i crazy?

Is a warp drive actually possible to create? If so, how long until we can develop one? Is it at all possible that they could be developed during our lifetimes? I'm asking because of this article...

I'm guessing folks have seen this... but if not. Pretty awesome. I have the annual Astronomy Magazine Calendar, and it never get's old. But this is a step up. Probably a better site for the vid...

Not kidding http://mysteriousuniverse.org/2015/04/nasa-may-have-accidentally-developed-a-warp-drive/ Astounding, is it true?

Hi all, I'm currently an applied mathematics student in my third year, and I plan to attend graduate school for pure or applied math. Physics and engineering deeply interest me, so I'm naturally drawn to the aerospace industry. Dazzling leaders like NASA and SpaceX are truly inspiring, and it...

http://www.nasa.gov/press/2015/march/nasa-s-hubble-chandra-find-clues-that-may-help-identify-dark-matter/index.html The take away seems to be that some ideas about dark matter may have problems. The possibilities checklist of dark matter interactions has been shortened. There are some really...

So I was reading this article about http://www.wired.com/2013/09/plutonium-238-problem/all/ and it got me thinking about possible substitutes. This is what I came up with. You make thin sheets of beryllium mixed with some kind of alpha particle emitter. You also make thin sheets of some...

From Google news, http://www.theregister.co.uk/2015/02/18/meteor_explodes_over_Earth's_beaver_in_hot_nasa_video/ Simple question, if you play the video in the link above the light from the meteor flairs up into a very large ball of light. Why don't we continue to see a relatively small point...

Can anyone point me in the direction of any published scientific work involving the study of Earth to Mars flight trajectories? I am thinking of researching this topic for a project and I would like to know about the work that has already been done.

Hi I have some questions for you people. My friend believes the first moon landing was faked, among a lot of other conspiracy's apparently proven all over the internet. The purpose of this post is to question his thoughts with some logical answers to some of the questions he has asked me. One...

Hi everyone, I am a High School student (final year) and am doing an extra-curricular project. Having complete autonomy on what we do the project on, I choose to design a High-Altitude Long-Endurance (HALE) UAV, such as the QinetiQ Zephyr [http://www.airforce-technology.com/projects/zephyr/] or...

http://www.cnet.com/news/nasa-wants-to-build-a-floating-city-above-the-clouds-of-venus/ This is something I've been hoping they would do for a long time. Let's hope it gets approved. What are your thoughts?

Hey guys, Lately I have been getting really really into the moon landings, and I want to take a look at some of the image archives to get a better look at what all they did and saw on the moon. Unfortunately, no mater how much I search, all I can seem to find is the same hundred or so photos...
