SpaceX Set to Test Raptor Engine Components at NASA Stennis

Nearly six months after announcing that SpaceX would be testing Raptor engine components at NASA's Stennis Space Center, a ribbon cutting ceremony this past Monday officially unveiled the newly refurbished E-2 test stand.

SpaceX has been working on the Raptor methane-fueled rocket engine since 2009. The new engine, a reusable engine is destined to be used in future versions of the Falcon Heavy and in the long term for the notional SpaceX Mars Colonial Transporter.

Testing is set to begin within the coming days after the E-2 test stand activation is completed a spokesperson for SpaceX confirmed to SpaceRef.

SpaceX will test Raptor injectors and combustion chambers during the initial phase at E-2 Cell 1. According to SpaceX they are still in the very early stages of the Raptor engine development program and this initial test phase will last 12 to 24 months with larger components to be tested afterwards presumably at their rocket engine development facility in McGregor, Texas.

"This is a great partnership between NASA and SpaceX," Stennis Center Director Rick Gilbrech said. "These types of activities are opening new doors of commercial space exploration for companies. SpaceX is another example of the outstanding progress America's commercial space industry is making, and we are happy to welcome them as our newest commercial test customer."

"SpaceX is proud to bring the Raptor testing program to NASA's Stennis Space Center and the great state of Mississippi," said Gwynne Shotwell, President and COO of SpaceX. "In partnership with NASA, SpaceX has helped create one of the most advanced engine testing facilities in the world, and we look forward to putting the stand to good use."

The ribbon cutting ceremony comes just a few days after SpaceX revealed it had completed the first test flight of the Falcon 9 Reusable (F9R) at their rocket development facility in McGregor, Texas.

Raptor is the first member of a family of methane-fueled rocket engines under development by SpaceX. It is specifically intended to power high performance lower and upper stages for SpaceX super-heavy launch vehicles. The engine will be powered by methane and liquid oxygen (LOX),[2] rather than the RP-1 kerosene and LOX used in all previous Falcon 9 upper stages, which use a Merlin vacuum engine. Earlier concepts for Raptor would have used liquid hydrogen (LH2) fuel rather than methane.

The Raptor engine will have over six times the thrust of the Merlin 1D vacuum engine that powers the second stage of the current Falcon 9, the Falcon 9 v1.1.

The broader Raptor concept “is a highly reusable methane staged-combustion engine that will power the next generation of SpaceX launch vehicles designed for the exploration and colonization of Mars.”[3]

Thrust (vac.) 4,400 kilonewtons (1,000,000 lbf)[1]
Isp (vac.) 363 s
Isp (SL) 321 s

Aerojet-Rocketdyne better get busy.

A methane-fueled heavy lift engine is, without doubt, the wave of the future for space beyond earth orbit.

When SpaceX has an IPO I will be buying.

Wow, very interesting! “Get your ass to Mars”!

No one will be able to compete with the Raptor engine. It outclasses everything.

SpaceX maintains proprietary knowledge of rocket engines even the government doesn’t know. Stuff that Russia and China would love to get their hands on. You can bet that if Obama knows something, so do the Muslims, and so do the Chinese.

Mars Colonial Transporter
http://en.wikipedia.org/wiki/Mars_Colonial_Transporter

Mars Colonial Transporter (MCT) is the name of the privately funded development project by U.S. company SpaceX to design and build a spaceflight system[1] of reusable rocket engines, launch vehicles and space capsules to transport humans to Mars and return to Earth.

As of 2014, SpaceX has begun development of the large rocket engine for the Mars Colonial Transporter, but the MCT is not projected to be operational until the mid-2020s.

Mars Colonial Transporter has been notionally described as being a large interplanetary spacecraft capable of taking 100 people at a time to Mars,[10] although early flights are expected to carry fewer people and more equipment.[4] The spacecraft has been notionally described as using a large water store to help shield occupants from space radiation and to possibly having a cabin oxygen content that is up to two times that which is found in Earth’s atmosphere.[4]

The Mars colony envisioned by Musk would start small, notionally an initial group of fewer than ten people. With time, Musk sees that such an outpost could grow into something much larger and become self-sustaining, perhaps up to as large as 80,000 people once it is established. Musk has stated that as aspirational price goal for such a trip might be on the order of US$500,000, something that “most people in advanced countries, in their mid-forties or something like that, could put together [to make the trip].”[4]

Before any people are transported to Mars, a number of cargo missions would be undertaken first in order to transport the requisite equipment, habitats and supplies.[11] Equipment that would accompany the early groups would include “machines to produce fertilizer, methane and oxygen from Mars’ atmospheric nitrogen and carbon dioxide and the planet’s subsurface water ice” as well as construction materials to build transparent domes for crop growth.[4]

Super-heavy lift launch vehicle

The super-heavy lift launch vehicle for MCT will consist of one or three 10-meter (33 ft)-diameter cores and use nine Raptor LOX/methane engines to power each core.[10][1] The rocket has not yet been named by SpaceX.[12] As of March 2014, no launch site has been selected for the super-heavy lift rocket, but SpaceX has indicated that their leased facility in Florida at Launch Pad 39A is not large enough to accommodate the vehicle, and that a new site would be built in order to launch the 10-meter diameter rocket.[12]

The MCT launch vehicle is intended to be reusable—making use of the SpaceX reusable technology that is currently being developed for Falcon 9 and Falcon Heavy[1]—and producing approximately 40 or 120 meganewtons (9,000,000 or 27,000,000 lbf) of thrust at liftoff.[1][10]

Kickstarter or another fundraising website could be used to fund a Mars colonist.

Methane fuel makes a Mars rocket. Carry along a little hydrogen, and you can make methane from the Mars atmosphere. Hmmm.

At least SpaceX figured out a few years back that a LOx- RP1 upper stage was a non-starter for heavy GEO missions. The Isp trade-off between LOx-LH2 and LOx-RP1 is huge.

Unfortunately, Rocketdyne kind of screwed the pooch back in the 80s with a poorly designed injector on an unstable LOx-Methane engine. To their credit, companies like XCOR and SpaceX have figured out that methane was not the bad actor, rather the poorly designed injector. Took ‘em long enough.

I'd go, too, if I had long enough to live. If I was 10 years old right now, I'd be saving paper route money for a ticket.
