I\u2019ve heard it my whole life, or what feels like my whole life anyway: Apollo 11 landed on the moon with less software than is in a typical high school graphing calculator. So I had to laugh when I read what SNC Space Systems corporate VP Mark Sirangelo said about the space shuttle: \u201cI have more software power in my laptop than the space shuttle had.\u201d<\/P><\/p>\n

Mark explains that the space shuttle was not a software-driven vehicle.<\/P><\/p>\n

He had plans to change this when Sierra Nevada Corp.<\/A> decided to reinvent the shuttle as part of an initiative from NASA. The goal? Develop low orbital spacecrafts that can carry cargo or\u2014as the case was with SNC\u2014people.<\/P><\/p>\n

To accomplish this, SNC decided to cross a spaceplane that had almost a decade of engineering development with an Atlas V rocket. Thus, the Dream Chaser was born.<\/P><\/p>\n

The Dream Chaser<\/A> is a reusable crewed suborbital and orbital spaceplane designed to carry up to seven people to and from low Earth orbit. This spaceplane launches vertically as you would expect with a spacecraft, but it can land horizontally on normal runways thanks to its lifting body.<\/P><\/p>\n

When it came to making the Dream Chaser a reality, SNC recognized the importance of collaboration. \u201cWe take the track that we\u2019re not experts in everything,\u201d Mark says in a Desktop Engineering<\/A> article. So to bring the project to completion, they took experts from across industries.<\/P><\/p>\n

Among those involved in the project are Lockheed Martin, United Launch Alliance, nine NASA centers and U.S. universities respectively, and Siemens PLM Software<\/A>.<\/P>
\n

While a multitude of companies makes for better innovation and collaboration, it can also complicate an already complex work environment. Just imagine all the different systems and data they\u2019d be working with!<\/P><\/p>\n

This is where Siemens PLM Software\u2019s role becomes evident. SNC could easily integrate with a multitude of companies using different software because NX<\/A> is open, so it works with multi-CAD data.<\/P><\/p>\n

SNC chose NX CAD<\/A> largely based on its ability to handle the large, complex models inherent in the Dream Chaser project without crashing. \u201cIn other products, CAD models took forever to load, save and manipulate,\u201d John Roth, SNC Space Systems vice president of Business Development says.<\/P><\/p>\n

Switching to NX resulted in time savings of 20% for SNC, John adds. Time savings are important, because of the Dream Chaser\u2019s increased complexity over the original space shuttle due to the amount of software it contains.<\/P><\/p>\n

The Dream Chaser is about more than just great software though. The key to its success, according to Mark, is great relationships and a common view.<\/P><\/p>\n
