The Mars Science Laboratory lifts off May Chan

Staff Reporter An important step towards landing humans on Mars began at precisely 10:02am (Eastern Time) on November 26, 2011 from Cape Canaveral Air Force Station. As spectators stared nervously at Launch Complex 41, the MSL spacecraft, which carried within it NASA’s car-sized Curiosity rover was lifted into orbit aboard a United Launch Alliance Atlas V 541. The Atlas V launch vehicle that helped MSL escape Earth’s gravity is powered with a sixton Russian-built RD-180 twochamber engine that produces about 860,200 pounds of thrust at sea level. Four solid rocket boosters, manufactured by Aerojet in Sacramento, California, assists the Atlas V launch vehicle in its

heavy lifting. Each of these boosters measures about 67 feet long and 5 feet in diameter and is jettisoned after a 92-second burn. “There’s a bit of anxiety at liftoff and launch,” Aerojet’s Executive Director of Space Launch Systems Pete Cova admitted during the kickoff of the long awaited mission to explore the possibilities of existence of microbial life on the Red Planet. “It’s fun, but it’s also stressful.” The blunt-nosed cone-shaped aeroshell payload fairing that made up the upper stage of the launch vehicle brought the total vehicle height to about 197 feet. 16.5 feet-diameter aluminumhoneycombs and a graphiteepoxy structure encapsulated both the Centaur second stage, which is powered by a svelte 370-pound Pratt and Whitney Rocketdyne RL10A-4-2, and the MSL spacecraft.

The Centaur’s engine, producing 22,300 lb of thrust, fired about 10 minutes after the launch, and then burned for seven minutes and shut off as scheduled to ensure the spacecraft goes into a 19-minute coast phase, before burning for another 8-minutes to send itself into the planetary trajectory. The planetary trajectory places the MSL on its way to Mars after splitting with the Centaur booster as the spacecraft enters the 44th minute of its flight. The crowd at NASA’s Kennedy Space Center burst into euphoria, cheering and applauding as the screen capturing the MSL and its route came alive. “We are now seeing nice, clean telemetry data” said the NASA announcer. NASA finally confirmed good contact with the MSL spacecraft as it entered the 53rd minute of its flight.

EcoEagles take unique car to competition

Over the past few years, Embry-Riddle Aeronautical University (ERAU) has made huge steps toward becoming an eco-friendly university. From the added solar water heaters on the roof of the Student Center to making all new buildings on campus eco-friendly, ERAU is going “green”. But it is not just the university that is going “green,” the students are taking the initiative too. More specifically, the members of the EcoEagles have started the EcoCAR 2 competition sponsored by U.S. Department of Energy, General Motors (GM) and Argonne National Lab, to name a few.

competition, which began in August 15, universities compete to prove they have the best environmentally friendly design. The EcoEagles have received their first choice architecture and are now able to continue to the next stage of the competition which includes designing models and simulations. Due to rules of the competition, specific details of their architecture cannot be released at this time. EcoEagles team leader, Brian Harries, said, “We are very excited we got accepted for our first choice architecture and we can move on with the design.” In the first year, each team chooses three different architectures that they will propose for their design. Each team must submit monthly deliverables to the Executive Steering Committee to ensure they

are on time with the Vehicle Development Process (VDP). At the end of the first year, teams show off their designs and compete at a tradeshow. In the second year, GM will donate a 2013 Chevy Malibu to each team. Each team will modify the car to their specific design. The goal of each team is to have a working prototype by the end of year two. They will then take their prototype and compete at GM’s Yuma Proving Ground. In the third year, each team will refine their vehicle to 99 percent production ready. In the automotive world, this means the car is refined to a level where it would be suitable for a showroom. In the only competition of its kind, the EcoEagles are stepping up this year in a big way and

distinguishing themselves from the rest of the competition with their unique designs. What is different about the EcoEagles’ design that stands out from their competition? Expanding their first design in EcoCar 1, their EcoCAR2 design is a biodiesel Plug-in Hybrid Electric Vehicle (PHEV). “Only prototypes have been attempted of this design, but currently there are no cars like this on the market,” Harries said of the biodiesel PHEV. “PHEVs allow a customer to charge at their house, enabling all electric driving.” But the EcoEagles aren’t stopping with their unique design. They are taking it one step further by creating their own biodiesel fuel. Led by Mechanical Engineering Graduate student

Michelle Rodio, this project started a year ago in her Clean Energy Systems class, where her group created projects on the benefits, emissions and environmental factors of biodiesel fuel. Today, she continues to work on perfecting the biodiesel fuel, which will have about “10 percent less energy than diesel, but 100 percent less carbon emissions,” Rodio said. She said her plan is to “make B100 but put different mixes into the facilities vehicles,” which will be used primarily in tractors that are used to mow the lawn at ERAU. “I plan to start out at B20 mix, which will be used in the EcoCAR2 competition, and then gradually work my way to higher amounts of biodiesel.” Her goal is to have biodiesel in a tractor by the end of January 2012.

The EcoCAR2 competition allows students to explore different opportunities. Harries said, “There is a big learning process that you go through that comes with building something that you can’t learn in class.” ERAU is one of two private schools in the competition and Harries said it is a “big platform to display what your school can do.” Dr. Marc Compere, the faculty advisor for EcoEagles said, “We have experience, support from the school and a great team of students—we are in it to win it!” Anyone is welcome to join EcoEagles. There are engineers that work on the designs and business students that make business plans, blogs and budgets. “We have an open door policy,” said Brian Harries.
