NASA Seeks Public’s Designs to Throw Shade in Space


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 information about the challenge, visit:…

This contest supports the NASA Innovative Advanced Concepts (NIAC) study of the HOEE concept.

UFOs are real, feds’ cover-up fueled by fear: ex-Pentagon whistleblower
April 30, 2021

…Aerospace Corporation
For senior Pentagon officials, Elizondo discovered, acknowledging the very existence of UFOs was “too much of a pill to swallow.” He recalled one superior who clumsily changed the subject by asking Elizondo how the Miami Dolphins football team was doing. “Some individuals have a problem with this topic because it interferes with their philosophical or maybe theological belief system.”
In fact, Elizondo claimed one senior official “told him to ‘Stop’” investigating UFOs — and asked Elizondo if he had “read your Bible lately?”
Elizondo asked where his boss was going with the non sequitur before acknowledging familiarity with the Good Book. As per Elizondo, he was then told, “‘Well, then you would know that these things are demonic and we should not be pursuing them.’ He wasn’t kidding. That’s exactly how he felt.”
Dr. Eric Davis, Ph.D., a former rocket scientist for the Air Force Research Laboratory and currently a scientist at government contractor the Aerospace Corporation, confirmed: “They objected to UFOs as being Satanic!”
The line of thinking is not restricted to America. Nick Pope saw similar incidents of religion trumping science in the UK. “Some objections come from people in government who think the phenomenon is real — but demonic,” Pope said. “Their belief seems to be that studying UFOs would thus give energy to attention-seeking demons, which should be avoided. This view comes, in part, from the biblical description of Satan as ‘the prince of the power of the air.’”
But then, even secular government officials who accept the reality of UFOs get cornered by exactly what kind of action should be taken and who should take it. “They can’t deal with it on a legislative basis or on a military operational basis; they can’t deal with it on the basis of a presidential policy,” said Davis. “So they let a finite group of engineers and scientists and investigators work [on it] together.” And their findings “just collect cobwebs in the classified storage warehouses.”
Luis “Lue” Elizondo today.
To the Stars Academy
Some of this may have also stemmed from a fear of panicking the public. As Elizondo told Politico, many of the UFO sightings were near vulnerable nuclear facilities, ships in the water and power plants. He added, “We had never seen anything like it.”

Put your finger over the image of the star in the telescope.

July 19, 2022 5:41 am

Not a viable application until we develop sci-fi like reactionless drives to move it around in spite of orbital mechanics and the shadow it creates would disturb the atmospheric optics.

Still best to put the telescope in space and use the shade on the ground over the scientists so they can work longer.

Also, the strange feathering along the edge would instantly negate any observable details from literally any source you aimed a telescope at. In astrophotography we use a device called a “bahtinov mask” which creates 3 sets of diffraction lines so that all you have to do to achieve focus is line the I up in the middle of the X in the image and you’re done. It obliterates any starfield details while doing this.

Since the above drawing has diffractive surfaces and is NOT in an occlusion tube, it is going to be reflecting diffractive light from ALL other sources in the direction of the “science” towards the ground telescope AND since the planet turns you’re gonna maybe have a few milliseconds to try to take an image… which will be blurry anyway.

Wow! What an outstanding piece of evidence for the general lack of scientific knowledge and practical engineering that is now pervasive in press releases being issued by NASA agencies.

To work in tandem with a telescope on Earth’s surface, the proposed “starshades” (more properly called occulting discs) would have to be located in a geostationary orbit above Earth’s surface so as to enable long duration telescopic imaging to detect the faint light from exoplanets.

If not in geostationary orbit, the rate of angular speed of the occulting disk across the night sky would very likely exceed the slew rate of large ground based telescopes when in imaging mode. Furthermore, imaging at such slew rates would introduce a massive amount of “noise” around the occulting disk as background stars “crossed” the telescope’s view of view/imaging.

Furthermore, the comment about the design requirement for a starshade in the above article:
“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.”
is both sophomoric and wrong on several levels:
— Being located in a geostationary orbit limits greatly limits the stars available for disk occulting to those within a very tight band (say ± 1° declination) above/below Earth’s projected equatorial plane. The whole sphere of stars surrounding Earth could not be occulted in the manner stated.
— Given the area needed to occult any given star at geostationary orbital altitude (about 22,300 miles directly above Earth’s equator), the “lowest possible mass” occulting disk will be very susceptible to orbital displacement from the forces of impinging solar wind and solar photons. (In this regard, a more massive starshield would be more stable and therefore better.) This logically implies there will be a need for continuous attitude control on each starshield, and since the above article specifically refers to use of “chemical thrusters” (not ion thrusters) used for “alignment” during observations, any given starshield employing such propulsion will most likely exhaust all usable chemical propellant is less than a year (IMHO).
— To remain in the geostationary orbital plane (within, say, ± 1° declination) the only allowable orbital change would be what is called “E-W stationkeeping” (in terms of orbital ephemeris, adjusting the angle, or right ascension, along the equatorial plane).

My bottom line takeaway: the above-cited NASA PR with associated Ultralight Starshade Structural Design Challenge (and $ prize money) is a great way for NASA to excite young people about space and astronomy—a very good thing—but has almost no chance of being practical long-term from scientific or engineering points of view.

Nevertheless, with extraordinary luck, NASA just might possibly be able to image an exoplanet that lies within the above defined telescope-starshield view restrictions. Is the possible payoff of such worth the certain high cost of implementing such a system?

To all readers of my above post:

Sorry, folks, I totally blew my above arguments with my very own sophomoric mistake! To wit:

Although a geostationary starshade would remain at a fixed position in the sky with respect to ground based telescopes, it would NOT remain fixed with the line of sight from any ground telescope to any given star. The Earth rotates through 360 degrees about its spin axis every 24 hours, so the stars NEVER would appear to be in a fixed position relative to Earth’s surface.

I am well aware that ground based observing telescopes have “clock drives” that continuously slew the telescopes so as to counteract any star’s apparent motion across the sky so that they appear to be “stationary” in the telescope’s eyepiece/imaging system . . . I totally spaced out in overlooking this obvious fact in my above reasoning.

Mea culpa. Mea maxim culpa.

What this really means is that any given starshade could not possibly be in orbit around the Earth but instead must be “hanging” in free space. Even an starshade in orbit around the Sun becomes problematic in this regard.

To occult any given star, the sunshield must be maneuverable to be along the Earth-star line of sight as the Earth revolves in its orbit around the Sun. Given that we can’t feasibly locate a starshade outside of our solar system, a stupendous amount of propellant will be required to PREVENT any starshield from going into orbit around the mass of the Sun.

Yes, it took me alittle thought to how it would work.

A starshade would IMHO best be in some L point — not reasonable to try preventing it from orbiting the sun. The surface telescope(s) using it would have to take multiple exposures over many days/weeks of a target in a very limited field of view. Best to have a space telescope(s) in similar L point placements where orientation/separation between them/starshade would be fairly constant. The telescopes and starshade(s) would obviously have to be able to change orientations (and positions to a small extent). I understand the Webb rotates slowly in its L point orbit — not sure if there are any truly “dead” points in the L points.

Gordon A. Dressler
Reply to  beng135
July 20, 2022 8:16 am

Indeed, the above NASA PR on the proposed concept of using a starshade is misleading because its second paragraph has this specific statement:
“The ideal design would allow for compact packaging and successful deployment once in its Earth orbit.”

That is what first set me off on the wrong path toward my (now seen as) initial bonehead explanation that only a geostationary orbit would work for the starshade.

If used in conjunction with ground-based telescopes, as proposed, the starshade could not be in any possible orbit . . . one around the Earth, one around the Moon, one around a Lagrange point, one around the Sun . . . because such orbital motion would always result in relative motion of the starshade relative to the Earth-star/exoplanet line of sight.

Given the very small angular separation between a potential exoplanet and its home star, as seen from Earth—on the order an arcsecond at best, typically milli-arcseconds or less —any orbital motion by the starshade would result in useful occultation times being on the order of milliseconds or less, far too short a time to take one image, or even hundreds of successive occultation images, to accumulate sufficient light to reveal the presence or absence of a exoplanet.

Even putting a telescope into space to use with a separate, remote starshade is not feasible (IMHO) because the space telescope, just like the starshade, must not be experiencing from any orbital motion when conducting such imaging. And like the starshade, the space telescope would require continuous precisely-variable propulsive thrusting to counteract the gravitational attraction of the Sun (as well as that of Earth and the Moon) that would otherwise cause it to move in inertial space.

I won’t even go further to address the necessity of precisely adjusting the starshade’s position in inertial space, as would be required to offset the stellar parallex that results from Earth’s orbit around the Sun, so as to obtain long duration occultation of any given star in the celestial sphere.

Bottom line: I do not see any possible way that the concept proposed by NASA could be made practical.
