Friday Night Lights ULA launches Delta IV Richard Weakley Advertising Manager On May 16 at 8:03 p.m. EST, a United Launch Alliance (ULA) Delta IV roared to space at sunset, lofting America’s newest GPS satellite to orbit from Cape Canaveral Air Force Station’s Space Launch Complex 37B. ULA attempted to launch this vehicle the day before, but the launch countdown was halted when the weather in the area did not present conditions acceptable for launching. The weather system moving through the central Florida region produced several severe thunderstorms but did bring cooler and very clear conditions for the launch on May 16. Launch occurred on time at the beginning of the launch window. The vehicle quickly accelerated off the launch pad due to the solid rocket boosters’ flight characteristics. Mach one was reached less than a minute into the flight. The two strapon solid boosters burned for approximately 90 seconds before being jettisoned. The RS-68 main engine fueled by liquid oxygen and liquid hydrogen burned for just over four minutes into the flight before the first stage (Common Booster Core)

was separated seven seconds later. Fifteen seconds after the Common Booster Core was separated, the second stage engine ignited, propelling the satellite until a little after 15 minutes into the flight. Ten seconds after this burn was initiated, the payload fairing was jettisoned since it is not needed anymore. The payload fairing protects the satellite while the launch vehicle is propelling it through the atmosphere. Approximately 15 minutes after liftoff, the upper stage engine shutdown, placing the rocket and satellite into a three hour coasting orbit. In order to change the orbit from elliptical into circular, the upper stage burned for another minute and half with spacecraft separation occurred a few seconds later. This type of mission profile allows for the satellite to be placed into the desired orbit directly, without using a sequence of orbit changes to place the satellite into an operational orbit for the mission. The Boeing-built GPS 2F-6 satellite is the sixth satellite and the latest addition to newest constellation of satellites on orbit. The GPS 2F constellation will have twelve satellites onboard when all are launched by 2016. The

new 2F GPS satellites offer greater precision, better timing and a longer operational life than the current generation of GPS satellites. This enhanced capability will improve the functionality of the vast array of GPS devices in the world today from car GPS receivers to GPS-guided weapons. GPS 2F-6 will replace an older GPS satellite launched from Cape Canaveral Air Force Station on a Delta II. The GPS satellite constellation is operated by the United States Air Force Space Command. ULA is a joint venture between Boeing and Lockheed Martin that is responsible for engineering, integration and infrastructure for the Atlas V and Delta IV launch vehicles. The Delta IV was first launched on Nov. 20, 2002 with a commercial communications satellite from Cape Canaveral Air Force Station. The Delta IV is an evolved expendable launch vehicle that can be configured with varying numbers of solid rocket boosters, Common Booster Cores and different payload fairing sizes. The engine on the Common Booster Core, the RS-68, is an American-built engine. Continued on A2 >>

New Planes Bring New Benefits Zachary Wilkinson Editor-In-Chief The Flight Department’s fleet replenishment is scheduled to begin over the 2014 summer, and a few of the aircraft have already arrived. A contract signed by Embry-Riddle Aeronautical University with Cessna Aircraft Co. highlights the purchases of 57 Cessna 172 Nav III’s with G1000 Avionics for both the Daytona Beach and Prescott campuses. Approximately half of Daytona Beach’s new Cessna fleet, comprising 21 aircraft, will be delivered over the next two months. The remaining half will follow next summer. The Cessna aircraft on the ramp today were acquired after the Christmas Day Tornado ravaged the fleet in 2006, and are due for replacement. The new planes will arrive painted in the same scheme currently displayed by N405ER, and are configured with three seats to increase their functionality as a trainer aircraft. The third seat allows an observer to easily witness what goes on up front. Observation is a vital part of training, for it can save a student money by giving them additional

experiences at no cost. . “Our data shows that students who observe flight activities finish their flight training fast and cheaper”, said Flight Department chair, Ken Byrnes. Observation benefits a student by allowing them to see things the flight crew may not see, and in doing so they witness error trends and learn to recognize them. Specifically, It can

also make CFI applicants sharper when it comes to watching for student errors. Students in the FastTrack CFI program are paired with a partner, and observation is an element of their training. A total of five new Piper Arrows will also arrive, each with the modern paint scheme so attractively displayed by N102ER. Continued on A2 >>
