NASA missions make it seem like the future is now – rovers exploring Mars with cutting-edge gadgets, a spacecraft venturing home with an asteroid sample, and a complex space telescope peering at the early universe. So, what's the next big thing? What might space missions in 2050 and beyond set out to discover?
One small NASA program aims to see what could be possible. The
NASA Innovative Advanced Concepts (NIAC) program, part of the agency's
Space Technology Mission Directorate, funds early-stage research into sci-fi
sounding, futuristic technology concepts. The goal is to find what might
work, what might not, and what exciting new ideas
researchers may come up with along the way.
During NIAC's annual Symposium Sept. 21-23, 2021,
researchers will present ideas that could one day be game-changers in space. Watch the event to learn more about
these four technology concepts and more.
1. Swimming micro-robots for ocean worlds.
Ocean worlds, where liquid oceans lie beneath miles of icy crust, are some
of the most likely locations in our solar system to harbor life – an enticing
prospect for scientists. Accessing and exploring these aquatic environments
present unique challenges. Ethan Schaler, a robotics
mechanical engineer at NASA’s Jet Propulsion Laboratory in Southern California,
is researching one promising idea for exploration: Using 3D printed,
centimeter-scale robots equipped with sensors and actuators. A mothercraft that
drilled through the ice and deployed the micro-bots would also wirelessly
control them using ultrasound waves.
2. Long-reach crawling and anchoring robots for Martian caves.
While swimming robots could be ideal for some destinations, others will
require something with a firmer grip. Marco Pavone, an
associate professor at Stanford University, is developing a potential solution.
His ReachBot concept could quickly crawl through caves, using extendable
booms to grasp over long distances. Its various features would allow small and
lightweight robots to move around in tricky environments, such as vertical
cliff walls or the rocky and uneven floors of caves on Mars.
3. Lightweight deployable structures that expand in space.
Getting extra-large spacecraft off Earth takes lots of planning, as the
size of what can go to space depends on how much a rocket can
fit. Multiple launches and in-space assembly have proven
successful in the past, but there could be another way. Assistant
professor at Carnegie Mellon University Zachary Manchester is
considering ways to integrate recent advances in mechanical
metamaterials into a lightweight deployable
structure design. Such a structure could be launched inside a single
rocket fairing and then deploy autonomously to a final size of the length of 10
football fields.
4. Seeding asteroids with fungi to create space soil.
Space habitat concepts come in all shapes and sizes. But all designs have a
common challenge requiring innovative thinking: How will space travelers
sustain themselves during long journeys? Jane Shevtsov,
working with Trans Astronautica Corporation, offers creating
soil from carbon-rich asteroid material. The fungi would physically break down
the material and chemically degrade any toxic substances. Similar
processes take place on Earth, like oyster mushrooms cleaning up
petroleum-contaminated soil. The NIAC research aims to find a way for future
space habitats to have ample green space and robust agricultural systems.
The 2021 NIAC symposium will kick off Tuesday, Sept. 21. A keynote
address by the Mars 2020 Planetary Protection
Lead Moogega Cooper will air on NASA Television, the agency’s website, and the NASA app.
NASA selects NIAC proposals through a peer-review process
that evaluates innovation and technical viability. All projects are still in
the early stages of development, with most requiring a decade or more of
technology maturation. They are not considered official NASA missions.
