Experimental Jet Flies Mach 10

 

An experimental scramjet being developed by Australian and American scientists was successfully tested at Mach 10 over the Australian outback. That's 6,835 mph, or 10 times time speed of sound.

Scientists used a regular rocket to launch the scramjet, because scramjets need supersonic airflow and thin atmosphere to operate effectively. (Scramjet = supersonic combustion ramjet.)

Researchers hope that the general technology they're testing today leads to high speed, long range flights and low-cost satellite launches.

  Thats Too Cool  
 
*Dork Alert*
You can't break Mach 10! Or was that warp 10? lol

  that must be like,  
 
faster than ludacris speed.

  Yea seniorgato  
 
Im betting it was only 9.95 ... wonder if its Intrepid class and has dual attack mode.

  uhh  
 
Is there a person in it when it goes that fast?

its still less than escape velocity... so probably

  never quite understood...  
 
escape velocity.. could someone please explain?

Why can you not continue to apply thrust at a lower velocity and eventually pull away from earth? Escape velocity is about what, Mach 37?

What happens if you had enough fuel to maintain a sub-escape velocity indefinatly? Do you just get to a certain height and then stall out? Even if you thrust is always perpendicular to the pull of gravity? Why? Gravity isn't exerting extra force at higher altitudes is it?
