Beyond Apollo: Saint 浪花直播 University Is Training Students for Tomorrow鈥檚 Challenges

07/18/2019

As the world looks to the sky to remember man鈥檚 first steps on the moon, students and faculty from Saint 浪花直播 University鈥檚 Parks College of Engineering, Aviation and Technology are looking ahead to their next mission 鈥� the launch of Argus-2 this fall.

Michael Swartwout, Ph.D., associate professor of aerospace and mechanical engineering at Parks, said SLU鈥檚 Argus-2 will be launched in October to the International Space Station (ISS). The Argus-2 is going into space as part of NASA鈥檚 Educational Launch of Nanosatellites (ELaNa) program.

鈥淭he best training for spacecraft engineers is to get something built and flying,鈥� Swartwout says. 鈥淚t鈥檚 to take an idea, get it engineered, to get it built and to get it into space.鈥�

The team will fly with the spacecraft down to the NanoRacks facility in Houston around Aug. 12. NanoRacks is the private company that handles the spacecraft ejection system on the space station.

Earlier this week, the team did an environmental test in Indianapolis, putting the spacecraft into a demonstration version of the ejection tube.

NanoRacks will take SLU鈥檚 spacecraft, load it into the ejection system with 10 others and deliver the whole stack for launch. An NG-12 cargo rocket will launch to the ISS in mid-October from NASA鈥檚 in Virginia.

鈥淭he ejection system will be brought into the ISS, put in storage and, eventually be moved into the airlock, where the will grab it and pull the ejection system into position outside the ISS,鈥� Swartwout said. 鈥淔rom there, individual spring-loaded doors are opened and the spacecraft inside are spring-ejected into orbit, away from the ISS.鈥�

That release is currently slated for January 2020.

NASA calls the 4-by-8-inch, 6-pound satellite Argus-2. The original Argus was lost to rocket failure in 2015.

Around SLU, students and faculty have taken to calling the Cube-Sat 鈥淢VP,鈥� because in their quest to create a more efficient spacecraft the Space 浪花直播 Lab decided to keep things simple and built the Minimum Viable Product that could still do something useful in space.

鈥淚t鈥檚 also our MVP or Most Valuable Player because after the loss of COPPER and Argus -1, our lab really wants a successful mission,鈥� Swartwout said.

Argus-2 first takes on some of the original Argus mission; the satellite will fly with a commercial SD memory card, and SLU鈥檚 lab will be routinely checking it for errors.

鈥淪pace radiation can damage/change the memory,鈥� Swartwout explained, 鈥淪uch that a 1 becomes a 0 or vice versa. We want to understand how often those errors occur, so we can determine things like how many copies of critical data do we need to store in memory to ensure that we have at least one good copy.鈥�

A camera will be capturing pictures of the Earth, and on-board software will identify 鈥渋nteresting鈥� features in those images. 浪花直播ers will then train the system in what is actually interesting, so it can learn to do it better on its own.

The second objective of Argus-2 is to take a baby-step towards SLU鈥檚 next space project, called DORRE. DORRE will be a small constellation of two or more spacecraft and two or more ground systems (telescopes). AI techniques will be used to automatically detect and sense natural events, such as auroras, thunderstorms or meteors.

鈥淭he long-term goal of DORRE is to demonstrate that we can move control of the mission from the ground (where all major decisions are made by people) up to the spacecraft,鈥� Swartwout said. 鈥淪uch a move is needed to enable better use of the limited communications resources and round-trip light delays for deep space missions to let the spacecraft more rapidly detect and respond to interesting, short-term science events.鈥�

A Storied History, A Bright Future

SLU students get hands-on learning experiences to prepare them for careers in innovation.

鈥淲e鈥檙e giving students the opportunities and experiences necessary to jump into a career in space,鈥� Swartwout said. 鈥淭hat in terms of the big SLU picture has been happening all along.鈥�

Parks alumni have participated in the launch of every NASA manned mission. In 2018, Fernando Abilleira (Parks 鈥�99, Madrid 鈥�01), worked on the Mars Insight Mission. In 2017, Apollo 11 astronaut Edwin 鈥淏uzz鈥� Aldrin thanked the SLU alumni who helped put America鈥檚 astronauts in orbit.

Aldrin spoke at SLU as part of the University鈥檚 student-run Great Issues Speakers Series. He told the SLU crowd that 鈥淪t. 浪花直播 has always played a major part in NASA activities,鈥� giving a special nod to members of the 鈥淥ld Mac Club鈥� 鈥� former employees of McDonnell Douglas 鈥� who helped get NASA crews to the moon.

SLU鈥檚 Space Systems 浪花直播 Laboratory has been actively working since 2009. Members of the lab have gone on to work for Boeing and other space contractors, including Space X.

Saint 浪花直播 University is a Catholic, Jesuit institution that values academic excellence, life-changing research, compassionate health care, and a strong commitment to faith and service. Founded in 1818, the University fosters the intellectual and character development of more than 13,000 students on campuses in St. 浪花直播 and Madrid, Spain. Building on a legacy of now more than 200 years, Saint 浪花直播 University continues to move forward with an unwavering commitment to a higher purpose, a greater good.
