Who Will Win the Google Lunar X PRIZE?

Thu, 06/24/2010 - 15:54

Twenty-one teams are hard at work trying to win the Google Lunar X PRIZE, a $30 million international competition to safely land a robot on the surface of the Moon. The GLXP folks released a video this week as an update on how the teams are progressing. The challenge is not only to land a robot on the Moon, but it also must complete a few tasks – and none of this is easy: travel at least 500 meters over the lunar surface, and send images and data back to Earth.

From a JPL press release.

NASA has released the first-ever airborne radar images of the deformation in Earth's surface caused by a major earthquake — the magnitude 7.2 temblor that rocked Mexico's state of Baja California and parts of the American Southwest on April 4, 2010. The data reveal that in the area studied, the quake moved the Calexico, Calif., region in a downward and southerly direction up to 80 centimeters (31 inches).

Cosmologists Provide Closest Measure of Elusive Neutrino

Thu, 06/24/2010 - 01:33

Slices through the SDSS 3-dimensional map of the distribution of galaxies. Earth is at the center, and each point represents a galaxy, typically containing about 100 billion stars. Galaxies are colored according to the ages of their stars, with the redder, more strongly clustered points showing galaxies that are made of older stars. The outer circle is at a distance of two billion light years. The region between the wedges was not mapped by the SDSS because dust in our own Galaxy obscures the view of the distant universe in these directions. Both slices contain all galaxies within -1.25 and 1.25 degrees declination. Credit: M. Blanton and the Sloan Digital Sky Survey.

Cosmologists – and not particle physicists — could be the ones who finally measure the mass of the elusive neutrino particle. A group of cosmologists have made their most accurate measurement yet of the mass of these mysterious so-called "ghost particles." They didn't use a giant particle detector but used data from the largest survey ever of galaxies, the Sloan Digital Sky Survey. While previous experiments had shown that neutrinos have a mass, it is thought to be so small that it was very hard to measure. But looking at the Sloan data on galaxies, PhD student Shawn Thomas and his advisers at University College London put the mass of a neutrino at no greater than 0.28 electron volts, which is less than a billionth of the mass of a single hydrogen atom. This is one of the most accurate measurements of the mass of a neutrino to date.

Likely, future interstellar flights will not include the exoplanet HD209458b as a featured get-away destination. Not only is this extrasolar planet a scorchingly hot world where the poisonous carbon monoxide atmosphere is being evaporated, but new observations show this gas giant also has superstorms with winds of 5,000 to 10,000 km per hour. "It's definitely not a place for the faint-hearted," said Ignas Snellen, from Leiden University in the Netherlands who led a team of astronomers using the Very Large Telescope (VLT) to observe HD209458b, one of the most-studied planets orbiting around other stars. But Snellen told Universe Today that being able to detect this superstorm is extremely exciting and bodes well for finding possible life on other, more Earth-like planets.

Tip number one on "How to impress your classmates:" Find a mysterious cave on Mars. A group of 16 seventh-graders at Evergreen Middle School in Cottonwood, California, USA found a dark pit that appears to be an opening to a cave on Mars. Dennis Mitchell's science class were examining Martian lava tubes as their project in the Mars Student Imaging Program offered by NASA and Arizona State University, which takes advantage of the huge database of images taken by the Mars Odyssey spacecraft. The students found the skylight pit on the slope of an equatorial volcano named Pavonis Mons, and it appears to be an entrance to an underground lava tube. Similar 'cave skylight' features have been found elsewhere on Mars, but this is the first seen on this volcano.

John Glenn: Keep the Space Shuttles Flying

US spaceflight legend John Glenn has weighed in on the current human spaceflight debate, releasing an 8-page paper outlining his feelings and a potential plan to allow US astronauts to keep launching on US vehicles. While Glenn supports President Barack Obama's plan to extend operations of the International Space Station and to forego returning to the Moon for the time being, he thinks retiring the space shuttles at this point is a mistake.

"The world's only heavy lift spacecraft and the U.S.'s only access to space should stay in operation until suitably replaced by a new and well tested heavy lift vehicle," Glenn wrote. "The Shuttle system is working extremely well, has had systems upgrades through the years, and has had "the bugs" worked out of it through many years of use. The Shuttle is probably the most complex vehicle ever assembled and flies in the harshest of environments. Why terminate a perfectly good system that has been made more safe and reliable through many years of development?"

Gulf Oil Leak: Day 62 Update

Mon, 06/21/2010 - 23:05

Here's the latest satellite image of the BP oil leak in the Gulf of Mexico. The oil keeps spreading towards the northeast, and appears as a maze of silvery-gray ribbons in this image from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite. The MODIS team said that the spot of black just north of the location of the oil well may be smoke; reports from the National Oceanic and Atmospheric Administration say that oil and gas continue to be captured and burned as part of the emergency response efforts.

The MODIS team is putting out about two satellite images of the region a day, which can be seen at this link.

Below is a video from reporter David Hammer from the Times-Picayune newspaper in New Orleans, Louisiana, who is covering the BP oil spill, explaining the latest developments as of June 21,2010. Apologies for the 15 second ad at the beginning, but Hammer provides a good overview of what has been happening.

Maybe ET's Calling, But We Have the Wrong Phone

Mon, 06/21/2010 - 21:48

The search (xkcd)


To date, SETI (Search for ExtraTerrestrial Intelligence) has focused on ETs who 'phone home' using the radio part of the electromagnetic spectrum, and even a very small region within that.

But what if ET's phone doesn't use radio waves? Sure the xkcd comic, is funny, but maybe it points to a deep flaw in our attempts to contact, or hear from, an ETI?

When Giuseppe Cocconi and Philip Morrison suggested the possibility of interstellar communication via electromagnetic waves in a 1959 paper in Nature, only radio was feasible, as we then had the ability to detect only artificial radio signals, if produced by ETIs with 1959 human technology. Since then we've developed the ability to detect a laser signal, brighter than the Sun (if only for a nanosecond) if it came from a source several light-years away … but lasers weren't invented then.

What might ET's equivalent of ants' pheromones be?

Another stunning image from the Cassini spacecraft, suitable for wallpaper on your desktop. Click image for larger version, or click here for a large 1.125 MB version.

This is Saturn's moon Dione, in crisp detail, against a hazy, ghostly Titan. Simply stunning.

The "wispy" terrain on Dione is visible, and on Titan are hints of atmospheric banding around Titan's north pole. This view looks toward the Saturn-facing hemisphere of Dione (1123 kilometers, 698 miles across) and Titan (5150 kilometers, 3200 miles across), and was taken on April 10, 2010.

No images available yet from Cassini's extremely close flyby of Titan over the weekend where it buzzed the hazy moon at an altitude of just 880 kilometers (547 miles) above the surface. (...)

Stunning Sunrise and Aurora, As Seen from the Space Station

Sun, 06/20/2010 - 21:30

Sunrise as seen by Doug Wheelock (Astro_Wheels on Twitter) from the ISS.

Expedition 23 astronaut Soichi Noguchi took and shared so many amazing images during his 6-month stay on board the International Space Station, and I was a little worried that his return to Earth would result in a bit of a let-down in the space imaging department. I now see I had nothing to fear: Three new members of the Expedition 24 crew arrived at the ISS late last week and Doug Wheelock seems to have filled Soichi's shoes (or socks, since they don't wear shoes on the ISS) quite nicely. He posted two new images today on his Twitpic page that are nothing short of stunning. This image, above of an orbital sunrise provides a great look at the ISS bathed in "morning" light.

"A stunning sunrise aboard the International Space Station, as seen from the Russian MRM1 Module. We're blessed with 16 sunrises each day!" Wheelock, a.k.a Astro_Wheels wrote.

See below for an aurora he captured over the South Pole.

Astronomy Without A Telescope – SETI 2.0

Sun, 06/20/2010 - 00:22

Credit: SETI Institute

Fifty years of eerie silence in the search for extra-terrestrial intelligence has prompted some rethinking about what we should be looking for.

After all, it’s unlikely that many civilizations would invest a lot of time and resources into broadcasting a Yoo-hoo, over here signal, so maybe we have to look for incidental signs of alien activity – anything from atmospheric pollution on an exoplanet to signs of stellar engineering undertaken by an alien civilization working to keep their aging star from turning into a red giant.(...)

Occultation Reveals Distant Kuiper Belt Object is Surprisingly Icy Bright

Fri, 06/18/2010 - 22:12

How do you study an extremely small planetary body in the dim outer reaches of our solar system? Get all your friends from around the world to wait for a very elusive – if not short-lived – special event. And in doing so, you may find something completely unexpected. Enter James Elliot from MIT, who worked with dozens of observatories and astronomers across the globe, including Jay Pasachoff from Williams College in Massachusetts, in an attempt to make observations of the Kuiper Belt Object 55636, (also known as 2002 TX300) a small body orbiting about 48 AU away from the Sun. Since this KBO is too small and distant for direct observations of its surface, the astronomers tracked and plotted its course, figuring out when it would pass in front of a distant star.

The KBO occulted, or passed in front of a bright background star, an event which lasted only 10 seconds. But in that short amount of time, the astronomers were able to determine the object's size and albedo. Both of these results were surprising.
