Assembling a 12 milion horsepower engine in 2 minutes

[Hog]

Shown below is the assembly of a RS-25D rocket engine, time lapsed down into 2 minutes. This engine is ME-2063 which is the only other RS-25D that has not been previously flown on a Space Shuttle. The other "rookie" engine is ME-2062.
Aside from ME-2062 and 2063 there are 14 other RS-25D engines that will be flown on NASA's new SLS (Space Launch System) rocket, with its debut launch scheduled for 2018. The mission is dubbed SLS-1(Space Launch System #1) or EM-1(Exploration Mission #1) is set to liftoff NLT(No Later Than) November, 2018.

SLS/EM-1 will use 4 RS-25D's including(all with extensive STS=Space Transportation System aka Space Shuttle experience):
ME-2045 flew on STS-89, 95, 92, 102 and 105 in Block IIA configuration and STS-110, 113, 121, 118, 127, 131 – and the final shuttle mission with Atlantis on STS-135 – in its full Block II configuration.
ME-2056 flew on STS-104 and 109 Block IIA, and STS-114 and STS-121 as a full Block II engine
ME-2058 flew on STS-116, 120, 124, 119, 129 and 133
ME-2060 flew on STS-127, 131 and STS-135

The Contingency Main Engines(or backup engines) for SLS/EM-1 are:
ME-2047 flew as a Block IIA configuration on STS 91, 96, 99,106, 98, 104, 109 and in fully evolved Block II configuration on STS 112, 115, 118, 123, 126, 128, 132, and 134.
ME-2059 flew in full Block II configuration on STS 117, 122, 125, 130, & STS 134
ME-2062 never been flown, built circa 2010(last engine built while Shuttle was still operational)
ME-2063 this "rookie" has also never been flown and built circa 2015.

And here is the 2 minute time lapsed video of ME-2063 being built by the crew at Aerojet/Rocketdyne. The 1st RS-25D that they have built since 2010.

ME-2063 is one of 4 RS5's scheduled to propel SLS's 1st "manned" mission with the new "Orion" capsule sometime in 2021.

These RS_25D engines were flown on Space Shuttles in groups of three engines. While used during the STS (Shuttle) program, these engines were referred to as SSME's or (Space Shuttle Main Engines). On Shuttle they were used as a re-useable engine. On the SLS rocket, these beauties will be used in groups of 4 engines on the "core stage" at a time and will only be used one single time before being dropped into the Indian Ocean.

There are enough RS-25 engines for 4 SLS missions, totaling 16 Main Engines. After these 16 Main Engines are used up, NASA has contracted Aerojet/Rocketdyne to build 6 more next generation RS-25 engines. These engines will have a single use design which is hoped will drop the $60 million price tag of the current RS-25D engines substantially.

Helping the SLS rocket up off the pad up to about 2000mph, there will be 2 SRBs or Solid Rocket Boosters. These Shuttle Derived Solid Boosters will use 5 segments instead 4 segments used on Shuttle. Using the current RS-25D engines producing 1,670,000 lbs of thrust, along with 2 5 segment SRBs the SLS rocket will be capable of lifting 70 metric tons to Low Earth Orbit.
These 2 boosters will deliver 7,200,000 lbs of thrust for a total 1st stage thrust of 8,870,000 lbs for the SLS 1st stage.
Shuttle made 6,780,000 lbs of thrust,
Saturn V made 7,648,000lbs of thrust during 1st stage propulsion from its five F-1
engines.
In the mid 2020's NASA will procure a next-generation SRBs along with 4 RS-25 core stage engines and 4- RL-10 second stage engines which will boost the launch mass up to 130 metric tons to LEO.

SLS evolution (Block II Cargo and Manned versions of SLS will be taller than the mighty Saturn -V rocket used for the United States Moon shots)

There are some cool things coming down the pipe from NASA. In July 14, 2015 the "New Horizons" probe (launched January 19, 2006 (2006-01-19)) will pass within 10,000 km or 6,400 miles of Pluto. It takes communications 4.5 hours to travel one way or 9 hours round trip.

Boeing and Space-X will start supplying rides to and from the
International Space Station. Instead of paying the Russian company Energia $77 million per seat to send up American and Canadian Astronauts (and other countries) into orbit aboard the Soyuz-TMA
capsules and Soyuz FG rockets.

SLS will send Astronauts to a Near Earth Object(a meteor) possibly the Moon, and eventually (after 2030) to Mars.

Plus the Space Shuttle Program, Apollo, Gemini, Mercury, Hubble Space Telescope, plus any NASA rocket and craft that has been launched since 1957.

All funded on less the 1/2 cent of every federal budget dollar. Since 1957 when NASA was started, the space agency has been budgeted less than $800 billion for all 58 years of its existence. This included all the projects
listed above, plus, the Space Shuttle Program, Apollo, Gemini, Mercury, Hubble Space Telescope, plus any NASA rocket and craft that has been launched since 1957.


This is less than 1 year of funding for the entire United States military.
