Ants Crew Anxious to Compete

All systems are go for SDSU’s ANTS project.

This is no picnic pest but one of three projects coming out of the Jerome J. Lohr College of Engineering that has been selected as a finalist in a NASA competition.

ANTS, short for Artemis Navigating Transporter System, is one of 15 finalists in the 2023 RASC-AL competition, which is short for Revolutionary Aerospace Systems Concepts – Academic Linkage. Five mechanical engineering majors and their adviser, associate professor Todd Letcher, built a lunar surface transporter vehicle. There were four different RASC-AL challenges this year, and SDSU was one of four finalists selected in the lunar vehicle contest.

Breaking the Ice Lunar Challenge

SDSU engineering students are competing against the best of all possible competition to build a product to operate in the worst of all possible conditions.

Space Trajectory, a team of mechanical and electrical engineering students, was one of 15 finalists selected for NASA’s Break the Ice Lunar Challenge, which is designed to develop new technologies that could support a sustained human presence on the moon by the end of the decade. With NASA scheduled to send astronauts to the surface of the moon in 2024, this has taken increased priority.

 

NASA has identified several technology gaps related to harvesting and moving large quantities of resources on the moon.

Those gaps include having hardware capable of operating in extreme cold and in permanent to near-permanent darkness. “Robotic systems for excavation will need to withstand the harsh environments inside permanently shadowed regions at the lunar South Pole, where ice has been observed and is the targeted landing site for crewed Artemis missions,” NASA reported while announcing the challenge.

“Technologies and hardware from the Break the Ice Lunar Challenge will get us one step closer to excavating icy regolith on the lunar surface, providing critical water resources and excavation activities needed to build the infrastructure on the moon,” according to Denise Morris, acting Centennial Challenges program manager at NASA’s Marshall Space Flight Center in Huntsville, Alabama.

Project Jack Drop is tethering its hopes in a NASA contest to a helium-filled balloon in a remote South Dakota field.

The project is one of three entries submitted by SDSU teams that have advanced to the finals of three different NASA contests. Project Jack Drop is entered in NASA’s FLOATing DRAGON Challenge. That’s NASA’s simplified title for the Formulate, Lift, Observe, And Testing; Data Recovery And Guided On-board Node (FLOATing DRAGON) Balloon Challenge.

 

If you think that is complicated, try autonomously detaching a 1-kilogram (2.2-pound) data recovery vault from a large balloon 120,000 feet in the stratosphere and safely steering that 3- by 4-inch box back to a designated landing spot undamaged. That’s what NASA is asking of the SDSU team and five other finalists from around the nation.

 

Six mechanical engineering students started working on Project Jack Drop at the start of school in late August. Conceptual designs were due Jan. 8. Notification of finalists was Jan. 30. The finalists were sent their $5,000 project stipend Feb. 9. Software design review is May 18. Mission readiness review is July 2. Testing is Aug. 15 at Fort Sumner, New Mexico.

 

Since being named a finalist, the team has been ordering supplies to turn their concept into a contraption and then seeing if their idea can fly, or at least float.
