Sculpture Puts You In Orbit With Satellites

Want to hear the rush of a satellite going by? Step inside this sound-filled interactive sculpture.

An entire fleet of satellites is out there right now circling our planet, but we earthlings don't tend to notice.

Now a light-filled interactive sculpture is making those NASA satellites feel real by assigning them unique sounds. Want to hear the rush of a satellite zipping by? Step right in.

Exquisite Exoplanetary Art: Photos

NASA commissioned the Orbit Pavilion sculpture to transform the trajectories of their usually invisible satellite fleet into a tangible experience for the public. Normally their 19 satellites pass by unseen as they gather crucial scientific data about our planet including weather patterns, ocean currents, and air quality.

The architects at StudioKCA in Brooklyn agreed to take on the challenge. "The satellites are collecting data streams," principal Jason Klimoski told Co.Design. "That doesn't really lend itself to good representation, so we had to think of a new creative way to do it."

Inspired by listening to a shell to hear the ocean, they decided to produce a similar effect for space. Shaped like a shell, the large sculpture contains 3,500 square feet of curved aluminum panels fitted together and bolted to an aluminum tube frame, representing orbital paths.

Each satellite was given a unique nature-inspired sound by composer and acoustics consultant Shane Myrbeck. The Orbit Pavilion uses real NASA tracking data. That means visitors who stand inside the sculpture's 3-D sound chamber get to "listen to the sounds of NASA's satellites as they fly over, under and around them, in real time," according to StudioKCA's project overview.

Here's what it's like:

After the nautilus-shaped sculpture debuted last year at the World Science Festival in New York City, the pavilion moved to NASA's Jet Propulsion Laboratory in Pasadena. It will stay there for a few more months before moving to the Huntington Botanical Gardens, a 120-acre space in San Marino, Calif.

The hope is that, by the time visitors step outside the Orbit Pavilion again, they've gotten to know the satellites better - sort of like social networking on a different level. And we should recognize them. After all, they're always keeping an eye out for us.

Exquisite Exoplanetary Art

Sept. 19, 2011 --

They're alien worlds orbiting distant stars far out of reach of detailed imaging by even our most advanced telescopes. And yet, day after day, we see vivid imaginings of these extrasolar planets with the help of the most talented space artists. The definition of an extrasolar planet -- or "exoplanet" -- is simply a planetary body orbiting a star beyond our solar system, and nearly 700 of these extrasolar worlds have been discovered so far (plus hundreds more "candidate" worlds). With the help of NASA's Kepler space telescope, the ESO's High Accuracy Radial velocity Planet Searcher (HARPS), French COROT space telescope and various other advanced exoplanet-hunting observatories, we are getting very good at detecting these worlds, but to glean some of the detail, we depend on artist's interpretations of fuzzy astronomical images and spectral analyses. That's the way it will be until we build a vast telescope that can directly image an exoplanet's atmosphere or physically travel to an alien star system. So, with the flurry of recent exoplanet discoveries, Discovery News has collected a few of the dazzling pieces of art born from one of the most profound searches mankind has ever carried out: the search for alien worlds orbiting other stars; a journey that may ultimately turn up a true "Earth-like" world.

The Transit

As an exoplanet passes in front of its star as viewed from Earth, a very slight dip in starlight brightness is detected. Observatories such as NASA's Kepler space telescope use this "transit method" to great effect, constantly detecting new worlds.

Hot Jupiters

Some exoplanets orbit close to their parent stars. Due to their close proximity and generally large size, worlds known as "hot Jupiters" are easier to spot than their smaller, more distant-orbiting cousins.

Habitable Worlds

The primary thrust of exoplanet hunting is to find small, rocky worlds that orbit within their stars' "habitable zones." The habitable zone, also known as the "Goldilocks zone," is the region surrounding a star that is neither too hot nor too cold. At this sweet spot, liquid water may exist on the exoplanet's surface. Where there's water, there's the potential for life.

A Phantom

Usually, exoplanet hunters look for the slight dimming of a star or a star's "wobble" to detect the presence of an exoplanet. However, in the case of Kepler-19c, its presence has been detected by analyzing its gravitational pull on another exoplanet, Kepler-19b. Kepler-19c is therefore the Phantom Menace of the exoplanet world.

Keeping Warm

The habitable zone seems to be the pinnacle of extraterrestrial living. If you're an alien with similar needs to life on Earth, then you'll need liquid water. If your planet exists outside your star's habitable zone, well, you're in trouble. Either your world will be frozen like a block of ice, or boiling like a kettle. But say if your world had the ability to extend your star's habitable zone? There may be some atmospheric factors that might keep water in a comfy liquid state. Even better, if you like deserts, a dry world could even be oddly beneficial.

Crazy Aurorae

Planets with a global magnetic field, like Earth, have some dazzling interactions with the winds emanating from their stars. The high-energy particles bombard the planet's atmosphere after being channeled by the magnetism. A wonderful auroral lightshow ensues. But say if there's an exoplanet, with a magnetosphere, orbiting really close to its star? Well, stand back! The entire world would become engulfed in a dancing show, 100-1000 times brighter than anything we see on Earth.

The "Candidates"

"Candidate" exoplanets are often mentioned, especially when talking about detections by the Kepler space telescope. But what does this mean? As a world passes in front of its star, slightly dimming the starlight, this isn't considered a "confirmed" exoplanet detection. To make sure that signal is real, more orbital passes of the exoplanet need to be logged before a bona fide discovery can be announced. Until then, these preliminary detections are called exoplanet candidates.

Angry Suns, Naked Planets

Exoplanets come in all sizes and all states of chaos. Some might have wonky orbits, others might be getting naked. Other times, they're simply being ripped apart by X-rays blasted from their parent star. Bummer.


Super-Earths get a lot of press. Mainly because "Earth" is mentioned. Sadly, most of these worlds are likely completely different to anything we'd call "Earth." And you can forget calling the vast majority of them "Earth-like." It's simply a size thing -- they're bigger than Earth, yet a lot smaller than Jupiter, hence their name, "super-Earth." Easy.

Let's Go!

For now, we have to make do with artist's renditions of exoplanets for us to visualize how they may look in their alien star systems. However, plans are afoot to send an unmanned probe to an interstellar destination. Although these plans may be several decades off, seeing close-up photographs of these truly alien worlds will be well worth the wait.
