Curious, he asserted it was likely or at least feasible that these four questions may be answerable within two decades given the course of research at the time in 1997.
I believe they were something along these lines:
Was there ever life on mars?
Is titan a laboratory for the origin of life (big moon of saturn)?
Is there intelligent life elsewhere?
What is the origin and fate of the universe?
The last two sound more lofty than the first two but he briefly discussed these questions in an early chapter of his book. I don't stay informed enough to know what has been found with regards to these questions but does anyone know?
Hello, I have an astrophysics question that I'd like some help with for a story I'm writing.
Neptune's two largest moons are Triton and Proteus. Proteus orbits Neptune once every 26.9 hours and Triton orbits Neptune once every 141.05 hours. The odd thing is that Triton orbits in the opposite direction as Proteus. Triton is the only moon in the solar system to do this.
My question is this, how many hours would Triton be behind Neptune if the observer was on Proteus?
Assume the following for easier calculations:
Alternatively, if anyone knows of a web based orbit simulator that can handle multiple moons of a planet, then I'd love to know where that is located to avoid any assumptions. THANK YOU!
Edit: Crossed out the second assumption because it didn't make any sense.
I'm currently studying business engineering, which is an interdisciplinary field combining aspects of technical engineering with business management and economics, covering a broad spectrum of knowledge. I'm contemplating pursuing another master's degree, specifically a Master of Science in Space Studies. This program only takes one year and appeals to me greatly due to my interest in space (I’m mostly thinking about it because I want to study an extra year and this seems to be the most interesting). However, I have several questions and would greatly appreciate your insights:
4)The space studies program at my university offers specializations in social sciences (a mix of economics, laws, etc.), science, and technical aspects—all related to space. Considering my background and interests, which specialization do you think would be most beneficial? While I have a solid foundation in economics, I find all three areas intriguing and am somewhat knowledgeable about each.
I've received mixed feedback so far searching online and really value honest opinions. Your insights could help me make a more informed decision.
Thanks in advance for your help! (I’m willling to delete this if this is the wrong subreddit for this)
I‘m 33 years old now and just wondering: will I ever go to space? I mean real space, not just a hop above 100km, but getting into orbit and staying there for a couple of days.
My earning is decent. So I could „easily“ spend something like 100-200k for such a trip. But how likely is that? Will there be a private space hotel soon? And what kind of rocket would be even able to offer a launch into LEO for less than 100k per person?
I put 25 years into the title because I guess it will be probably impossible to do such a trip in your 60s or 70s.
