Water, Wind, and Fire: New Ways to Access Space
Henry Neiberlien News Editor
What’s Inside
Starfighters Aerospace, a private company based at Kennedy Space Center, maintains a fleet of antique Lockheed F-104 fighter jets capable of speeds more than Mach 2, and they want to launch satellites with them. Although the F-104 first flew in 1956, this aircraft is unique in the speed it can achieve, and that speed allows it to fly up to attitudes of 120,000 feet on a parabolic suborbital trajectory. Starfighters Aerospace has developed a small missile sized launcher for microsatellites, and the F-104 can launch it during a parabolic arc. For low weight payloads, this is a very cost-effective method for launch. The F-104 can carry a 1500-pound payload to 100,000 feet in less than four minutes, and twin seat aircraft are also available. This means that these flights can also be used for suborbital science,
suborbital human spaceflight, commercial astronaut training, and spacesuit testing. Utilizing this cold-war era plane instead of spending R&D funds to develop a vehicle of similar performance is an excellent use of existing resources, especially since most people probably did not even think it was an option. Another company, Ripple Aerospace located in Norway, wants to make use of the largest spaceport on the planet, the oceans. Ripple Aerospace has proposed a new launch vehicle called Jormungandr, or The Sea Serpent. This rocket is powered by an aerospike engine, which is a very high performance rocket engine that does not compromise aerodynamic efficiency. Its nozzle is the opposite of a conventional rocket motor. Instead of a bell, the nozzle resembles a spike; it is also where it gets its name. The motor is not the most exciting part of the vehicle. It is designed to be built in a dry-dock,

towed out to sea, the back half sunk into the ocean, and then launched vertically. Utilizing the ocean to launch rockets is revolutionary; it allows coastal nations that have shipbuilding facilities to have access to space. However, finding calm waters in the North Sea will be a challenge, not
to mention the damage salt water does to fragile components such as space vehicles. In New Zealand, the American commercial spaceflight company Rocketlab plans to tackle the cost of launching to space. They are developing a new lightweight launch vehicle made of composite mate-
rials called the Electron, and they plan to launch one every week. The high-frequency of these launches will drive the cost down for the customer and hopefully offer more companies and countries the opportunity to launch into LEO. The test program for the Electron

is scheduled to conclude this year with the first commercial flights commencing in 2017 with a starting price of $4.9million. This price seems like a lot to the average citizen, but it is drastically lower than the price offered by other launch providers. These companies are opening the door for more people to access space with innovative ideas. Everybody knows about the big players like United Launch Alliance, and SpaceX. However, the aerospace industry might want to keep an eye on these companies as small satellite technology continues to attract more and more money and attention. Perhaps innovative ideas are incubating in the minds of students here at Embry-Riddle, and our students are the future of the industry. I know we all cannot wait to see what technological innovations and industry changing events our students can provide to commercial spaceflight.
