Searching the universe for Earth-like planets is like looking for a needle
in a haystack. To further this exploration, NASA is supporting the early-stage
study of a concept for a hybrid observatory that would combine a ground-based
telescope with a space-based starshade. These devices block glare from stars
when observing planets outside our solar system, known as exoplanets, from the
ground. The Hybrid Observatory for
Earth-like Exoplanets (HOEE) would convert the largest
ground telescopes into the most powerful planet finders ever made – and the
public has an opportunity to be part of this groundbreaking endeavor.
The Ultralight
Starshade Structural Design Challenge asks participants
to develop a lightweight starshade structure that could be used as part of the
HOEE concept. The ideal design would allow for compact packaging and successful
deployment once in its Earth orbit. It must also have the lowest possible mass
so that chemical thrusters can keep it aligned during observations and
propulsion systems can change its orbit to observe different targets – all
while using as little fuel as possible.
One way to pinpoint an exoplanet in the vast darkness of space and
determine its potential habitability, is to observe the light it reflects as it
orbits its star. This light is influenced by surface minerals, oceans,
continents, weather, vegetation, and the gases that make up its atmosphere. But
the star often produces a glare when observing the planets from ground-based
telescopes, disrupting observations. Starshades cast a dark shadow over the
star without blocking the light of its planets, providing observers a better
view.
“The hybrid observatory might help us answer some of the most pressing
questions about extraterrestrial life,” said Dr. John Mather, senior
astrophysicist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland,
and senior project scientist for the James Webb Space Telescope. “Observing many systems would help answer the question of why
configurations like our own are rare and why none is quite like home. It is
truly exciting that the public can be part of this revolutionary effort. I
can’t wait to see what ideas they bring to the table.”
The top five submissions will share a prize purse of $7,000. The contest
deadline is Aug. 22. The challenge is administered by GrabCAD. For more

This contest supports the NASA Innovative Advanced Concepts (NIAC) study of the HOEE concept. The NASA Tournament Lab, part of the Prizes, Challenges, and Crowdsourcing program, manages the challenge. The program supports public competitions and crowdsourcing as tools to advance NASA research and development and other mission needs. NIAC and the Prizes, Challenges, and Crowdsourcing program are part of NASA's Space Technology Mission Directorate.
