Jul 09, †Ј Step One: Know What Your Rocket Needs to Do. In order to know what kind of rocket youТre going to build, you need to know its requirements. For the sake of this hypothetical example, letТs say the new rocket you need to build is to be designed .
Well, what kind of rocket are you going to create? All rockets, after all, are not created equal Ч the world is full of a variety of rockets, all designed for different purposes. A bold mission requires a bold rocket.
Step Two: Establish Mission Parameters. Over history, there have been numerous studies of how to get to Mars, so you take the best data you can get and figure out what it takes to execute those missions.
Many engineers think your lander may measure up to how to shift gears in a 10 speed truck feet across, so you need a payload volume big enough to carry it.
Step Three: Call in Experts. You work with other rocket designers, in both the government and commercial spaceflight worlds. You listen to a lot of ideas. And I mean, a LOT of ideas. Step Four: Start Drawing. You start creating rocket designs.
You work from a blank sheet of paper. In fact, you get a lot of blank sheets of paper. Reams of paper, really. Step Five: Whittle Down the Possibilities. The challenge, it turns out, is not to design a rocket capable of supporting human missions to Mars. The challenge is designing the BEST rocket for the mission. And the real challenge of doing that is knowing which rocket is best. Once you have enough power, more power makes less difference. As you probably guessed, this question is not completely hypothetical; four years ago, this exact scenario led to the birth of Space Launch System.
Engineers were tasked with designing the metric-ton Mars rocket described above. They called in government and industry experts. They reviewed more than 1, possible designs for the vehicle. In the case of the SLS, some concepts were easy to reject: there were clearly better choices, for example, than the rocket that was too wide to fit out of the giant how to insulate a garage ceiling with living space above of the Vehicle Assembly Building at Kennedy Space Center.
But which was best? External constraints had to be considered Ч in addition to the guideline that the rocket had to support human deep space exploration, national policy said it had to use, where possible, resources from the then-about-to-end shuttle program and earlier Constellation development effort. Any of the designs could have met this guideline; NASA worked to pick the design, and then identify existing resources that could facilitate its development. NASA chose three additional standards to measure the rockets Ч any qualified design would be judged by how well it met standards of safety, affordability and sustainability.
Each of the three had strengths and weaknesses; engineers studied and debated the pros and cons of each. Ultimately, while the Saturn-like rocket was a good design, the time and cost needed to design, build, and launch it was too great.
The smaller-rocket-derived design, in contrast, offered development advantages over the kerosene vehicle since the existing hardware and support systems provided a head start, but its complexity counted against it in the safety measurement.
The remaining design, based on a combination of upgrades to how to build a real rocket ship systems and new developments, provided advantages in shortening development time and reducing costs, and offering safety advantages through the use of proven propulsion systems. Step Six: What you can take through customs the Best Design.
And so from the thousands, one remained Ч the design that could not only carry out the mission to Mars, but could do so most safely, affordably and sustainably. Join in the conversation: Visit our Facebook page to comment on the post about this blog.

One of Langley's jobs is to create new and innovative technologies to meet the challenges of space flight and lower the cost of future space missions. With technological advances in many areas and expanded needs and capabilities of space missions, NASA researchers face unlimited possibilities.
As they work through a series of steps from concept inception to full-scale design, they may hit stumbling blocks and be forced to retrace their steps and sometimes even start over.
At every turn, however, they are pioneering their way through science and engineering, turning theories into reality. Their designs must pass final qualification tests and be proven cost efficient. Only then will they be considered for service. This personnel transporter has made it to the mock-up stage and awaits further approval before being built.
What is the purpose of the mission? That question begins the avalanche of other questions which lead toward design requirements. What is the payload, how big is it, how much acceleration and entry heating must it take? Once these, and many more requirements are decided, a study is done to determine whether the mission performance requirement can be met. Step 1. The HL was designed by NASA Langley to carry astronauts back and forth to the space station and to serve as an emergency return vehicle while they are there.
The nature of the payload and its special needs help determine the design - shape, size and configuration - of the space vehicle. If people are going, there are obvious unique requirements, such as seating capacity, entrance and exit hatches and access to certain systems. The configuration of the spacecraft must provide for all of the support systems, such as communications, electrical systems and life support.
Step 2. Researchers considered various configurations for the HL External access to subsystems, to allow for easy maintenance, and enough room for eight passengers were two top priorities. NASA Langley engineers must determine the craft's general operation before launch and upon its return. They must analyze the aerodynamic, or air flow, characteristics of the configuration, as well as monitor structural stress, effects of high speed, heat tolerances and the performance trajectory, or course it flies to space and back.
Engineers must consider appropriate new materials for the spaceship that could minimize cost and weight. Every pound of extra structure may take up to 10 pounds more in total launch weight to get it into space - and back. And every pound of structure raises the cost of the mission. Step 3.
The HL design was analyzed for aerodynamics in wind tunnels and by computer, to understand how the air would flow around it and would affect its flight into space and back.
Once the spaceship has been designed, it must be certified for flight through a series of performance, vibration and thermal tests. It is now time to test the actual structure with models of the design. It is not necessary to build an entire spaceship for initial testing. Instead, engineers build and test the individual components. A wing, for example, may be subjected to tests that are not appropriate for any other part of the vehicle. After initial testing, any parts of the spaceship structure or internal systems which do not meet performance requirements are then redesigned and retested.
Step 4. Water entry tests using a small-scale model of the actual design. Once a final design passes initial tests, a full-scale model, or mock-up, is fabricated in fiber glass or other inexpensive materials. Afterward, an actual prototype, called the flight model, may be built and then tested to assure the quality of design. If it passes many hours of tests including a series of experimental flight tests, it is ready for production and operation.
Step 5. A mock-up of the interior design of the HL enables real astronauts to determine if they can move and function as planned. Current space missions require a launch vehicle with rocket stages to get a spaceship such as the HL into space.
As we approach the new millennium, NASA Langley is using its experience to help industry develop and introduce the next generation of space vehicles. One of its top priorities is a fully reusable spaceship, a launch vehicle, which would fly to space and back as a single unit or single stage.
Depending on the mission, the reusable launch vehicle could support sophisticated, high-precision, deployable instruments for specific scientific research. A prototype of this vehicle, the X, is slated to fly in NASA Langley engineers also have an active role in the design of the International Space Station, the components of which are currently being built. NASA Langley's current development of next generation launch vehicles follows a systemized course from inception to prototypes to flight vehicles.
With the goal to reuse vehicle components and eliminate multi-stage rockets, NASA Langley researchers have brought us into the 21st Century and will continue to meet the ever changing and expanding requirements of space missions. There's a problem with your browser or settings.
