April 29, 2022 — When NASA’s Blue Origin rocket launches in January 2023, its cargo will embrace a 4-by-4-by-8-inch container that weighs somewhat greater than a pound.
Inside that container will likely be two sponges, a syringe, a motherboard, two cameras, LED mild strips and the intelligence and curiosity of six college students at Arizona State College’s Preparatory Academy Polytechnic STEM Excessive College.
These six college students — Deaglan Salado, Hafsa Kaysan, Samantha Llagas, Elijah Linman, Ryan Robinson and Sawyer Ganes — have been winners in NASA’s TechRise Problem and are being given $1,500 to design an experiment that can happen through the January flight.
The experiment, as titled within the three-page written presentation despatched to NASA: “How will Hydrophobic and Non-Hydrophobic Sponges React with Water in Microgravity?”
Earlier than entering into sponges and area, it ought to be famous what the six college students already achieved simply by having their challenge chosen. 600 colleges from throughout the nation despatched in entries, and colleges might ship in multiple entry. (ASU Poly submitted greater than a dozen). Of these tons of of entries, solely 57 have been chosen.
Robinson: “We submitted it, after which I used to be pondering nothing was going to occur after that.”
Ganes: “All of us submitted it only for our grade for our class, and once we have been chosen, we have been like, ‘How did this occur?’”
Llagas: “It’s simply so bizarre.”
Talking of bizarre, how does a highschool pupil provide you with the thought to see if sponges soak up water in area like they do, properly, in your toilet?
Trainer Irvin Goutcher mentioned every of his courses had a brainstorming session, concepts have been tossed round, somebody talked about sponges, after which the project-based studying class, which the six college students attend, created the plan and wrote the paper and diagram submitted to NASA.
The experiment, whereas sounding a bit intimidating — Non-hydrophobic sponges? Microgravity? — actually isn’t. Hydrophobic means waterproof. Hydrophobic sprays for, say, waterproofing sneakers could be discovered on Amazon.
One of many sponges that goes into the container will likely be sprayed. (And, sure, we’re speaking a couple of sponge you may buy at Walmart). The opposite sponge will likely be non-hydrophobic. The experiment will decide how the completely different sponges react in microgravity.
“We simply wish to know what the impact of gravity is on that,” Goutcher mentioned. “Is the gravity what’s pulling the water into the sponge, or is it the impact the sponge has with some form of capillary motion the place it is going to soak up the water whether or not there’s gravity or not?”
The outcomes of the experiment might have sensible functions in future area missions.
“We all know that storing water in area is without doubt one of the issues NASA needs to attain for future journey as a result of folks want water,” Kaysan mentioned. “It might have many makes use of, even for rising vegetation.”
Whereas the premise of the experiment is straightforward sufficient, the execution of it’s exceedingly troublesome. All the objects which have to suit into the container — the cameras, sponges, lights, syringe, and so forth. — can’t weigh greater than a pound due to the burden restrict set by NASA. The scholars are pondering of utilizing micro-cameras that match onto a canine’s collar.
The experiment will likely be programmed robotically so it is going to detect the launch, after which activate when the 11- to 16-minute flight hits microgravity.
“We’ve one shot,” Salado mentioned.
The syringe will likely be powered by an actuator that controls the timing of the injection. The scholars will watch the experiment from ASU Poly, assuming the cameras within the container work, and file it on a micro-SD reminiscence card. As soon as the rocket returns to Earth, NASA will ship the container to the scholars — hopefully.
“They mentioned that half, they don’t know, as a result of typically rockets land good and typically they don’t,” Goutcher mentioned.
Through Zoom, the scholars met with NASA officers for the primary time on Monday. Their accomplished container field needs to be shipped to NASA by the tip of September, however Goutcher is hoping the scholars could have it completed by the tip of Could, to coincide with the tip of the semester.
Till then, the six college students will write code for the motherboard, discover sponges appropriate for the experiment, take a look at pressurized syringes and recognize day by day that NASA is taking their thought into area.
“Yeah,” Robinson mentioned. “That’s cool.”
