KSC-06-S-00047

You're watching NASA Direct. Music. My name is Garrett Skrobot of the Launch Service Program, and I'm the mission integration manager for ST5. My role as the ST5 mission integration manager is to lead the integration team. The integration team consists of four members: myself, the mission manager; the integration engineer; the program integration manager; and last, the launch site integration manager. ST5 is a constellation of three spacecraft, each weighing about 50 pounds. The three spacecraft will perform three functions on orbit. It will have new technologies. It will conduct formation flying and also study the Earth's magnetic fields. My name is Julie Schneringer. I'm the lead launch site integration manager from Kennedy Space Center's Resident Office at Vandenberg Air Force Base. Jeff Ehrsam is the assigned launch site integration manager for the ST5 mission. A launch site integration manager works with the spacecraft customer to provide the facilities and services they require for final processing of their satellite and integration to the launch vehicle. I'm James Wood, one of the two chief engineers of NASA's Launch Services Program. We're principally responsible for the technical decision-making that goes on while we integrate a unique NASA mission on a commercial launch service. One of our big challenges is to ensure that we have good, well-qualified designs for each of the unique modifications that we need to make to the launch vehicle in order to accommodate each NASA spacecraft's special needs. Let's meet some of the talented engineers that make this happen. My name is Bob Henry. I'm the Pegasus XL vehicle systems engineer. The Pegasus XL vehicle is the smallest vehicle that NASA uses to place spacecraft into orbit. With the aerodynamic lift generated by its unique, delta-shaped wing, Pegasus typically delivers satellites into orbit in a little over 10 minutes. As the vehicle systems engineer, it is my job to ensure our hardware, software and mission-analysis pieces come together for a successful launch. It is a challenge. There is never a dull moment, because each mission profile and spacecraft is unique. I'm Bill Benson. As controls, flight software and flight design analysts, Jon Bauschlicher, Rob and Mary and I work with our counterparts at the Orbital Sciences Corporation to design the launch vehicle trajectory for the ST5 mission. We create and run computer simulations of the Pegasus guidance, navigation and control system to make sure that it will fly the rocket to the correct orbit and will maintain control of the vehicle throughout the flight. Our goal is to make sure that the Pegasus rocket has enough performance margin so that the ST5 mission will have a high probability of success. Hi. I'm Chuck Dovale, launch director for the ST5 mission. You've just met key individuals that have been working the ST5 mission and, actually, it's taken hundreds to get to this point. Now, we're close to drop. So, sit back, relax and enjoy the mission. Pegasus, away_
