Haunting the Web Since 1999
After traveling 4 billion miles, accomplishing an exhilarating landing on a 84,000-mph moving target, and, after 57 hours of work in an unfortunately dark location, successfully sending a valedictory round of data, the ESA’s history-making Philae probe falls into slumber. “We still hope that at a later stage of the mission, perhaps when we are nearer to the Sun, we might have enough solar illumination to wake up the lander and re-establish communication.” Rest well, little lander — ya did good.
This came out while I was in Seattle and I’ve been meaning to catch up: By measuring the cosmic background radiation still extant from the Big Bang, the ESA’s Planck satellite gives us our most detailed map of the universe yet.
“[T]he new satellite data underscored the existence of puzzling anomalies that may yet lead theorists back to the drawing board. The universe appears to be slightly lumpier, with bigger and more hot and cold spots in the northern half of the sky as seen from Earth than toward the south, for example. And there is a large, unexplained cool spot in the northern hemisphere.”
I find these maps particularly fascinating because, as I said when NASA’s WMAP returned its data in 2003 (and here in 2002), I spent the summer of 1992 poring over the original COBE DMR version of this map for my high school senior thesis, in order to determine whether the radiation exhibited a fractal distribution. (And, honestly, how early 90’s is that?)
“‘A.M.S. has confirmed with exquisite precision and to high energy one of the most exciting mysteries in astrophysics and particle physics,’ said Justin Vandenbroucke, of the University of Wisconsin and Stanford’s SLAC National Accelerator Laboratory.” In related news, NASA’s recently-installed Alpha Magnetic Spectrometer on the ISS is helping physicists and cosmologists get to the bottom of the dark matter mystery.
The A.M.S. has “confirmed previous reports that local interstellar space is crackling with an unexplained abundance of high energy particles, especially positrons, the antimatter version of the familiar electrons that constitute electricity and chemistry…’Over the coming months, A.M.S. will be able to tell us conclusively whether these positrons are a signal for dark matter, or whether they have some other origin.’“
“The European Space Agency is seeking volunteers for a 520 day mission to Mars. The trip will begin in early 2010 and include 30 days on the surface of the red planet. The only requirements are that candidates must be 20-50 years old, in good health and no taller than six feet. You must be able to speak English or Russian and have experience in medicine, biology or engineering. You also must be a resident of one of the ESA Member States, which rules out Americans, but not our Canadian brothers & sisters.“
Down and Out in Paris or London (or Toronto)? Well, if you’re short of cash and heavy on free time, it seems the ESA is running a 520-day Mission-to-Mars simulation. Please don’t be alarmed just because this is how Capricorn One starts. “If you’re interested in volunteering, more information can be found here.” (RT @Joe Hill.)
Europa, Enceladus…Titan? The ESA’s Cassini-Huygens probe discovers a liquid lake on Saturn’s largest moon, although it’s definitely not water. ““Detection of liquid ethane in Ontario Lacus confirms a long-held idea that lakes and seas filled with methane and ethane exist on Titan.” [Via Quiddity.]
ESA’s Mars Express sends back some impressive postcards from Mars. “Over the last five years its stereo, high resolution camera has taken thousands of images of the surface, revealing the planet’s awe inspiring beauty in unprecedented detail.”
The European Space Agency releases the first new pics from their recent “Express” mission to Venus. The Venus Express probe entered Venusian orbit on Tuesday.
The LA Times examines the beginnings of the second lunar space race, which will involve, among others, the US, Europe, China, and India. “Some researchers even have a name for the first lunar city: Jamestown, in honor of the first English settlement in the New World.“
Some intriguing new finds right here in our neighborhood: The ESA posts some very nice images of a frozen Martian lake, and astronomers have found a large object (and its moon) orbiting our sun outside Pluto.
“I’d give it a 50-50 shot that you could find it somewhere underground. But then that’s a guess.” The NYT surveys the current thinking about prospects of Martian life, and how astrobiologists plan to go about proving or disproving its existence. (To wit, the European Space Agency plans to send an tricked-up rover to the red planet after 2011…hopefully, it’ll get past the Dubya Pentagon’s rash of Moonraker weapons.) Update: In somewhat related news (to the second story), Slate‘s Fred Kaplan assesses the Pentagon’s overly enthusiastic vision for ground-based future tech.
