Stanford’s 2021 NIAC fellows working to bring sci-fi concepts to real space exploration

Two “out there” tips from Stanford college acquire NASA funding in hopes that they could substantially advance space exploration.

A mothership that emits electrical power with a laser beam to manipulate a probe craft in deep space. A robot that extends its arms to climb in Martian caverns and grasp objects.

These are improvements you may possibly hope to see in a science fiction movie – just one where the hero embarks on interplanetary journey throughout the photo voltaic program. But they are also are visionary tips from the minds of Stanford University scientists that have already received funding from the NASA Ground breaking Advanced Principles (NIAC) System.

As 2021 NIAC fellows, Sigrid Close and Marco Pavone – each associate professors of aeronautics and astronautics – are currently being given the likelihood to show the feasibility of their creative concepts, regarded as SCATTER and ReachBot. Shut and Pavone are among 14 other NIAC Stage I recipients who are obtaining $a hundred twenty five,000 to fund nine-month experiments on their research tips. Nevertheless their tips may possibly seem to be out of this entire world, should they thrive, they’d substantially effects space exploration.


In excess of the class of her funding, Shut is doing the job on proving her principle SCATTER, which stands for Sustained CubeSat/CHIPSat Action By means of Transmitted Electromagnetic Radiation. The plan is that a spaceship on a mission to deep space will be in a position to electrical power and manage a probe with a transmitter.

SCATTER focuses on a mission to Uranus, but in accordance to Close’s collaborator Nicolas Lee, a research engineer in the Division of Aeronautics and Astronautics, it can be utilized to other deep space missions as very well.

“In standard, smaller spacecraft have been powered by possibly photo voltaic or batteries,” explained Lee. But on a mission to a planet much out in the photo voltaic program, like Uranus, working with the Sun’s rays is not feasible. “In terms of the other alternatives with batteries, you have confined everyday living so you can use that for incredibly limited-expression missions.”

By beaming a laser from the mothercraft onto a probe, which can then change the vitality from the laser into electrical vitality, the group believes they can sustain prolonged-expression missions, particularly with smaller, lower mass probes.

“A several several years back, we commenced imagining, ‘Well, we’re constantly speaking about safeguarding satellites from the space natural environment,’ ” explained Shut. Then, they wondered, What if we can harness some of that vitality?

“Even nevertheless it’s distinctive from how it commenced, we commenced hunting at distinctive ways to power spacecraft working with the space environment and then just kind of extended it from there,” she described.

In the coming months, Shut and Lee will be doing the job on figuring out how smaller and basic they can make the deployable spacecraft so that they can use the laser to not only electrical power the spacecraft but converse and manage pointing with it.

According to Lee, the funding they acquire will actually allow the scientists to examine the mission principle side of SCATTER.

“It’s an honor,” explained Shut. “I’m actually grateful to NASA and the NIAC committee for offering us this option.”


When requested about the inspiration guiding ReachBot, Andrew Bylard, a graduate college student in aeronautics and astronautics who performs in Pavone’s lab, is brief to cite an unlikely couple: Spider-Person villain Health practitioner Octopus and lovable Star Wars sidekick BB-eight.

“The plan of ReachBot was born from this kind of technological hole that exists in robotics right now,” explained Stephanie Schneider, who is also pursuing her PhD in aeronautics and astronautics when a member of Pavone’s lab.

In microgravity environments like the Global Place Station or when climbing beneath gravity on Mars or the moon, crawling robots have to seize anchor factors to transfer and manipulate objects without the need of floating away or slipping. If anchor factors are several and much between, the robots are confined by how much they can arrive at.

ReachBot increases its arrive at working with “extendable booms,” which extend out from its sides, like measuring tape. The booms can be rolled up compactly and, when unrolled, they are sturdy cylinders with lightweight grippers on the finishes – which can seize objects, be made use of to anchor the bot to a selected place or press off of surfaces like a leg to transfer ReachBot close to.

A single persuasive use for a bot like this is the exploration of Mars. While the Mars rovers are excellent at rolling along the area, ReachBot would be able of climbing on cliffs and by means of caves.

Right now, the group is in the early stages of doing the job on a hardware prototype of the bot. In excess of the class of their NIAC Stage I funding, they program to focus on proving the feasibility of ReachBot principle, like doing the job with mechanical engineering professor Mark Cutkosky and geological sciences professor Mathieu Lapôtre to design and style new lightweight spiny grippers and to refine the science goals for a climbing mission on Mars.

The major problem to prevail over will be doing the job on the motion and maneuvering of ReachBot’s “arms.” But the rewards for a robot that masters mobile manipulation beneath these complicated gravity restraints are higher.

“The best pay-off for space robotics is actually to empower your science,” explained Pavone.

Rethinking results

Not all NIAC fellows make it earlier Stage I. The assignments are often described as “high-threat, higher-reward”: tips that may possibly seem to be technologically out-there, but should they thrive, they’d have a massive effects on space exploration.

“I imagine it’s actually crucial that, as a neighborhood, we fund these forms of reducing-edge tips and get people pitfalls,” explained Shut, whose principle for a smaller satellite to characterize asteroid surfaces received NIAC Stage I funding in 2018.

Pavone, who was formerly awarded a NIAC Stage I fellowship in 2011 for his principle of a hopping robot for navigating on asteroids and comets, thinks it’s crucial to have a distinctive outlook on what “failure” suggests.

“Even if we fail – or in standard just one of these concepts fails – commonly what comes about is that in the course of the system you learn some other things, or some pieces of the principle that you develop could be useful for other needs,” explained Pavone.

“So yeah, quite a few of these concepts fail in the perception that the precise proposed mission is often in no way flown but if you search at the broader picture, I would really argue that most of the concepts thrive.”
