Hi! I'm curious what your take on this is. I'm taking an introduction to U.S. Government course and my professor was discussing the inefficiencies of the public sector; the discussion on politics isn't relevant here but he did make an interesting point about space travel. He argued that the...

The following is a five-year-old post on one of NASA's websites. https://www.nasaspaceflight.com/2015/04/evaluating-nasas-futuristic-em-drive/?fbclid=IwAR02ifoAVrPGa0StAxsTjIuS3b08fUOyMcPh1-nBjeiwgwWkI3H7jnA0Has It exposes the holes in the state of affairs at that moment -- first, the article...

It's common knowledge that it takes about 3 days to get to the moon. With a Hohmann transfer, I get a transit time of 5 days, not 3. I see NASA used something called "trans-lunar injection". Is this distinct from a Hohmann transfer, and more time efficient? What makes this trajectory different...

Press release The Concorde could only fly supersonic while over the open ocean - the sonic boom was too loud. NASA is looking for aircraft designs that are much quieter. While the X-59 itself isn't very practical for passenger transport it might have some direct military applications and help...

NASA has proposed a mission to Alpha Centuri: https://en.wikipedia.org/wiki/2069_Alpha_Centauri_mission This mission would involve a spacecraft traveling at 10% of light speed and therefore relativistic effects could be somewhat significant. Let's assume this spacecraft is carrying a...

Yup. Newspapers have it. Again. Note the example "news" article with a very tiny disclaimer. Here are wikipedia's take, some NASA information, and a news article. They are all links and therefore are transient and could change. https://en.wikipedia.org/wiki/2018_LF16...

I was wondering, how does NASA actually calculate their super exact Ephemerides?

One idea for a moon base would be reinforced concrete domes, but is pouring concrete in a total vacuum even possible? Wouldn't the water just evaporate, or is there another material we could use instead of water? Are the ingredients of concrete plentiful on the moon, or could we synthesize them...

NASA decided to stop *WFIRST and concentrate on Mars project (send humans to Mars). What do you think about it? In my opinion, since a lot of ventures have begun space developments such as SpaceX and this proves that rockets make money, NASA should tackle WFIRST. Generally, we cannot earn...

Hi, Please could someone kindly explain how zero weightlessness is achieved in this aircraft. I have tried to use my own understanding and what I have read online. My ideas are: To experience weightlessness the plane must be in freefall so the only force acting on it must be gravity. Since...

What can we learn from a solar eclipse that the NASA IRIS program doesn't tell us? (and why)

How accurate do you think NASA's eclipse calculations are? Will that aircraft provide accurate moon trajectory?

Trying to figure out how many particles would bombard an astronaut during a solar proton event. Given that the most possible is around 43,000 particle flux units (pfu) according to NASA. First calculating steradians, assuming a person is 1m^2, 1/(1E9)^2=1E-18. My calculation yields (43000...
