If you have yet had the chance to make that dream a reality, well, the time has come, friend.

NASA has tweeted that they're now accepting new applications for the next batch of astronauts. Now, to apply, you must have the following qualifications:

1.) You must be a U.S. Citizen

2.) You must have a Master's degree in a STEM field.
In case you're ignorant to the meaning of the STEM acronym, it stands for science, technology, engineering, and math. So, if your Master's is in any of the aforementioned realms of study, then you're good to go.

3.) Two years of professional experience in your field.

And finally...

4.) You must pass the NASA physical. Basically, you can't be an astronaut and a couch potato, sorry.

Good luck!
