HUNTSVILLE, Ala. NASAs Super Guppy aircraft made an appearance in Huntsville earlier this weekarriving July 10 and departing July 11at the Redstone Arsenalairfield, adjacent to the agencys Marshall Space Flight Center (MSFC). The aircraft was in town to retrieve the MSFC-manufactured Space Launch System (SLS) Orion Stage Adapter (OSA) structural test article (STA) and transport the hardware to Lockheed Martinin Colorado.

MSFC recently completed integrated structural testing on the OSA STA, along with the Launch Vehicle Stage Adapter (LVSA) STA, the Interim Cryogenic Propulsion Stage (ICPS)STA, and other SLS / Orion test components.

Brent Gaddes, NASAs OSA Manager, explained that Lockheed, Orions primary contractor, will use the OSA STA for structural testing, for acoustic testing, [and for] . . . loadal testing, that has to do with how it vibrates when its excited at certain frequencies,to confirm the soundness of the spacecraft design.

The flight version of the OSA will connect the SLS Exploration Mission 1(EM-1) ICPS tothe integrated Orion spacecraft / service module.

The Super Guppy hasa cargo compartment 25 feet (7.62 meters) in diameter and 111 feet (33.83 meters) long. The aircraft is capable of transportingup to 45,000 pounds (20,412 kilograms). However, its most unique feature is a hinged nose that can swing open up to 110 degrees, allowing frontal loading.A lock and disconnect system at the fuselage break allows the nose to be opened and closed without disrupting the flight / engine controls.

Retired astronautGregory C. Ray J Johnson, a member of the STS-125 crew, and current Super Guppy commander / pilot, explained some of the difficulties in flying the aircraft:Guppy has no autopilot. One pilot flies for an hour, and the other pilot flies for an hour, and then you switch off and eventually land it. Very high stick forces. Frankly, quite a beast to land in crosswinds, so a lot of effort is done in the landing phase.

Flying the aircraft can be fatiguing and tiring, stated Tom Ryan, also a Super Guppy pilot, Sometimes its dancing with a lady and other times its wrestling a dragon.

SLS is NASAs new super-heavy-lift launch vehicle, which, among other capabilities, will carry astronauts to orbit in the Orion spacecraft for missions to the Moon, Mars, and beyond. Its first flight, Exploration Mission One (EM-1), an uncrewed flight around the Moon, is expected to take place in 2019.

Scott earned both a Bachelor's Degree in public administration, and a law degree, from Samford University in Birmingham, Alabama. He currently practices law in the Birmingham suburb of Homewood. Scott first remembers visiting Marshall Space Flight Center in 1978 to get an up-close look at the first orbiter, Enterprise, which had been transported to Huntsville for dynamic testing. More recently, in 2006, he participated in an effort at the United States Space and Rocket Center (USSRC) to restore the long-neglected Skylab 1-G Trainer. This led to a volunteer position, with the USSRC curator, where he worked for several years maintaining exhibits and archival material, including flown space hardware. Scott attended the STS - 110, 116 and 135 shuttle launches, along with Ares I-X, Atlas V MSL and Delta IV NROL-15 launches. More recently, he covered the Atlas V SBIRS GEO-2 and MAVEN launches, along with the Antares ORB-1, SpaceX CRS-3, and Orion EFT-1 launches.
