Reasons to Land on a Comet: What the Rosetta Mission Can Learn

After a journey that took more than a decade, the world is scheduled to witness a first when the European Space Agency’s Rosetta mission attempts to land a small spacecraft on the surface of a comet. The attempt will take place on Wednesday, at speeds of about 34,000 miles per hour.

The mission is a potential breakthrough in the study of comets. These chunks of ice and dust are leftovers from the formation of planets, often considered space “icebergs” given their age and distance from the sun. The water that resides in comets is likely the key to sustaining future deep-space missions—a celestial gasoline station, in a sense. Beyond water, comets such as the now-famous 67P are thought to harbor complex organic molecules, some of the ingredients needed for the formation of intelligent life.

“I think that humans have to go into space more and take ownership of the solar system,” says Denton Ebel, chairman of the division of physical sciences at the American Museum of Natural History, calling efforts such as Rosetta “the logical next step” of human space exploration.

There is yet another reason underlying the space agency’s financial and engineering feat: to prove it’s possible. Before attempting to land on the comet, the spacecraft will have whipped around the earth three times, followed by Mars, to obtain the necessary gravitational acceleration to rendezvous with a comet. The Rosetta craft will discharge a 220-pound landing probe, called Philae, to settle in a relatively clear spot only about 1/3-mile square.

“It’s technically one of the most difficult missions ever,” Ebel says. “This mission is amazingly ambitious.”

Other reasons to visit a comet include getting a better understanding of how massive space rocks are constructed, which could prove crucial if future earthlings ever need to intercept and prevent a doomsday scenario. There is also the issue of manned deep-space exploration and using the abundant resources found in comets and asteroids, mainly water and noxious gases but also precious metals. “How is the water locked up in a comet? We don’t really understand that at all,” Ebel says.

Future space explorers will almost certainly need to stop for water en route. Bring water from earth into space costs about $23,000 per pound, according to Planetary Resources, which plans to mine asteroids. The hydrogen and oxygen in water is also the basis for rocket fuel that will be produced in space.

The Rosetta mission was launched in March 2004 and reached Comet 67P/Churyumov-Gerasimenko on Aug. 6, where it has been orbiting about 14 miles from the surface. The comet is about 2.5 miles across at its widest point.

Confirmation of the Philae lander’s fate is expected to arrive at about 10:36 a.m. EST at the mission control in Darmstadt, Germany, following a seven-hour descent to the comet. The agency has deployed a full array of social media to chronicle the landing, including collaborating with a futuristic film dramatization starring Game of Thrones actor Aidan Gillan and a soundtrack of the sub-audible magnetic emissions from the comet, sped up so they can be heard. Come Wednesday, there will be tweets.

COSMIC RADIO

Hearing the silence… I have often wondered if humans, and other creatures, might not just be sensitive to these sounds (though not as sounds, but as electromagnetic vibrations, similar to being sensitive to a powerful magnetic field) through their brain and body, and if it would not be worthwhile to invent a miniaturized for-home-use radio telescope that could detect, discriminate, and convert these sounds for human listening and recording.

This device would have to be programmable, it would have to be sensitive enough to detect and track specific “sound sources and frequencies,” within the given and desired detection ranges, and it might even later lead to a in-home Cosmic TV (which could convert such sounds and vibrations into visual images similar to the way TV converts radio waves into visual images) for viewing such signals.

 

NASA releases actual recordings from space — and they’re absolutely breathtaking

on October 20, 2014, 10:45am
Earlier this year, Lefse Records released The Space Project, in which acts like Beach House, Spiritualized, The Antlers, and more used actual recordings from the Voyager space probe to create songs and soundscapes. Though a neat gimmick, with some intriguing submissions, the resulting album didn’t necessarily reflect the true sonic aesthetic of our solar system. For that, we turn to NASA, who has shared actual electromagnetic recordings taken from throughout our very own solar system.No one may be able to hear you scream in space, but that whole great, black abyss miles above our heads is just teeming with noises. From the brooding, slightly ambient rumblings of Saturn and its rings to the more romantic Neptune, which sounds like sitting on a back porch in Tennesse in mid-July, our solar system’s soundtrack is as emotionally-nuanced as it is almost cinematic. Just wait till you hear what Uranus sounds like, though.Listen in below. Or, enjoy live, 24-hour sounds via Radio Astronomy.

NOW YOU’RE GETTING IT…
