t-minus 10 9 8 7 and we have been in
dart 5 4 3
one zero and liftoff
one of NASA's largest ongoing projects
is the Space Launch System or SLS which
will one day allow us to explore deep
space destinations like asteroids and
eventually Mars in order to make the SLS
a success NASA centers must collaborate
with one another to accomplish mission
goals and reach major milestones two of
the center's collaborating on the SLS
project are Marshall Space Flight Center
in Huntsville Alabama and Stennis Space
Center in Hancock County Mississippi
while Marshall is a home to the SLS
program in the liquid engines office
Stennis Space Center has long been known
as the agency's largest rocket testing
facility and they have been extremely
busy with the testing of the upgraded
rs.25 engines in fact all rs.25 engine
testing happens exclusively at Stennis
Space Center
if these engines look familiar to you it
may be due to the fact that they were
used as a space shuttle main engine for
the last 30 years compared to the three
rs.25 engines that the Space Shuttle had
the SLS will utilize four of them to
produce 2 million pounds of thrust the
thorough testing of the rs.25 plays an
essential role in upholding NASA's high
standards of efficient and reliable
engines did you know in 1985 several of
the rocket complex test stands currently
being used to test these engines at
Stennis Space Center were deemed
national historic landmarks due to their
significance in the development of the
Saturn 5 rocket used for the Apollo
missions for more detailed information
about NASA's rs.25 engines you can find
the conference paper titled next
generation rs.25 engines for the NASA
space launch system on the nasa
technical report server or NTR s the NTR
s is one of the world's largest
repositories of aerospace STI and
features records ranging from the NACA
era to today's cutting-edge research
that's all for today thanks for watching
and we'll see you next time
