#514233 — NASA's shuttle-era engines have one last job

NASA's shuttle-era engines have one last job

"If it isn’t broken, don’t fix it. That’s the mentality at NASA, 
which is test-firing the RS-25 rocket engines that will serve as 
the main engines for the Space Launch System. (Video via NASA)

These are the same engines that powered the Space Shuttles — 
literally. The design has proved so reliable NASA has been 
refurbishing and reusing the same rockets for 34 years. Of the 
16 RS-25s standing by for SLS duty, 14 of them have already been 
to space. (Video via NASA)"

This sounds like they are severely behind the schedule lol.

   That was also the case with the Saturn Rocket during the Apollo
   program.

Hmm, not Wernher von Braun once again, please. Since you are so 
knowledgeable, how many black men landed on the moon? Are there blacks in 
the system right now? Can they not just float in zero gravity like the 
others, or what?

None.  How well you know.

But the implicit assumption is wrong, as it takes years to find and train an 
astronaut for such a mission.

> Are there blacks in the system right now?

Try, for one of many examples, the current NASA Administrator Charles 
'Charlie' F. Bolden, jr., former Space Shuttle astronaut.

See also: <https://en.wikipedia.org/wiki/List_of_black_astronauts>

You can find their work status in the individual articles.

So you are a racist, too.  One more reason to killfile you for good.

Are we racists because you are not able to understand questions?
