It’s Not Just The Astronauts That Are Getting Older

Universe Today - Wed, 03/10/2010 - 7:47am

Representing what may be the first long term lunar environmental impact study, recent laser ranging data from the Apache Point Observatory in New Mexico suggests the Lunar Ranging Retro Reflectors (LRRRs) left on the Moon by Apollo missions 11, 14 and 15 are beginning to shows signs of age.(...)

Scientists have found evidence of a catastrophic event they believe was responsible for halting the birth of stars in a galaxy in the early Universe. According to their findings, just 3 billion years after the Big Bang, a massive galaxy exploded in a series of blasts trillions of times more powerful than any caused by an atomic bomb. The blasts happened every second for millions of years. "We are looking into the past and seeing a catastrophic event that essentially switched off star formation and halted the growth of a typical massive galaxy in the local Universe," said lead author Dr. Dave Alexander from Durham University.

Updated at 9:40 EST Tuesday:

SpaceX just released the official word on what happened with Tuesday's 3.5 second test-fire of the Falcon 9 rocket. The test aborted immediately after it started, and a a spin start system failure forced the early shutdown. The Falcon 9 sits on Launch Complex 40 at Cape Canaveral Air Force Station, and from the Kennedy Space Center press site, (about 4 miles away) a muffled bang was heard at the time of ignition, 1:41 pm EST. "Today SpaceX performed our first Static Fire for the Falcon 9 launch vehicle," said Emily Shankin from SpaceX in a press release. "We counted down to an T-2 seconds and aborted on Spin Start. Given that this was our first abort event on this pad, we decided to scrub for the day to get a good look at the rocket before trying again. Everything looks great at first glance."

Step right up — you can now get your very own jetpack. That's right, a real, not-science-fiction-honest-to-goodness jetpack. New Zealander Glenn Martin has been working on perfecting his jetpack for 30 years, and in 1998 created the Martin Aircraft Company to develop and market his idea. Now, the jetpack has become a reality. The 200-horsepower, dual-propeller is designed to fly average-sized person for 48 km (30 miles) in 30 minutes on 18 liters (5 gallons) of gas. The newest model can also reach heights of 2,400 meters (about 1.5 miles). Price? $100,000. "They are a helluva lot of fun to fly," said Martin.

Possibility of Past Water on Mars Takes a Hit

Universe Today - Tue, 03/09/2010 - 1:47pm

Details from the Ascraeus channel (red), meandering across the surface of Mars. The insets in the black boxes show close-ups of some of the structures that lava can form: (left) branched channels, (middle) a snaking channel and (right) rootless vents; the rootless vents are also marked by yellow spots on the main image. Credit: Jacob Bleacher

Images of Mars taken from orbit show a massive system of riverbeds and canyons etched by water. Or maybe not. A new study of one channel shows that it was formed by lava flow and not water, and the results make "a strong case that fluid lava can produce channels that look very much like water-generated features," said Jim Zimbelman from the Smithsonian Institution in Washington, one of the researchers. "So, we should not jump to a water-related conclusion when we see such channels on other planets."

Universe Puzzle No. 4

Universe Today - Mon, 03/08/2010 - 9:54am


As with last week's Universe Puzzle, something that cannot be answered by five minutes spent googling, a puzzle that requires you to cudgel your brains a bit, and do some lateral thinking. This is a puzzle on a "Universal" topic – astronomy and astronomers; space, satellites, missions, and astronauts; planets, moons, telescopes, and so on.

What's the next number in the sequence? 401, 172, 85.2

There are no prizes for the first correct answer – there may not even be just one correct answer – posted as a comment (the judge's decision – mine! – will be final), but I do hope that you'll have lots of fun.

Post your guesses in the comments section, and check back on Wednesday at this same post to find the answer. Good luck!

UPDATE: Answer has been posted below.

Taking The Pulse Of A Supernova – NGC 4490

Universe Today - Sun, 03/07/2010 - 4:43pm


NGC 4490/4485 – T. Grossman, D. Hager and R. Johnson

Way out yonder some 40 to 50 million light years away in the constellation of Canes Venetici is a pair of interacting galaxies sometimes referred to as "The Cocoon". These two mis-shaped blobs of star stuff have already made their closest approach to each other and are now parting ways. Between them stretches a trail of stars that spans some 24,000 light years as they face each other showing off their numerous star-forming regions. But where there is life… There is death. Let's put our finger right on the pulse of a supernova. (...)

Classify this one under the same nonsense as the "Bigfoot on Mars" the wooden plank on Mars, or perhaps even the "Face on Mars." Just an optical illusions, folks from a very, very zoomed in image from the Mars rovers. The Sun newspaper seemingly started this foolishness on what must have been a slow news day.

Bolden: There is No "Plan B" In Development

Several news sources reported Thursday that NASA Administrator Charlie Bolden had asked senior managers to come up with an alternate plan for the newly proposed NASA budget after members of Congress indicated they wanted to reject a White House proposal to cancel the Constellation program and hire private companies to bring astronauts to the ISS. But today, Bolden issued a memo saying there is no "Plan B" and that he only asked two agency directors to help develop an accelerated plan for research and development on a heavy lift launch vehicle. The lack of heavy lift capability is one of the big sticking points for many on the new plan.

"I have not asked anyone to develop an alternative to that budget and plan," Bolden wrote, "and I don't want anybody to do so. Rather, I have asked – and am asking – for input on how the exceptional talents and capabilities we have developed in our organization can best be applied going forward to advance the elements of our new plan."

Could Phobos Be Hollow?

Back in the 1950s and 1960s, there was some speculation that Mars' moon Phobos could possibly be hollow due to the its unusual orbital characteristics. While scientists now agree that the moon is very likely not hollow, vast caverns may exist within the moon, and it might be a porous body instead of solid. The Mars Express spacecraft made a close flyby of Phobos on Wednesday to help provide more data on the interior of Phobos, and all indications are the event was a big success. The spacecraft skimmed smoothly over the odd-shaped moon at just 67 km, the closest any manmade object has ever been. No images were taken from this flyby. Instead all the instruments were turned off so that ground stations could listen for a pure radio signal of how Phobos "tugged" on the spacecraft. Scientists say the data collected could help unlock the origin of Phobos and other ‘second generation’ moons.

Listen to the audio of this podcast at this link.

You can also read the interviews below.

Hi, this is Nancy Atkinson from Universe Today. Right now I'm at Kennedy Space Center, and I've had the opportunity to see a couple of launches and cover other events that normally, I'd be back home watching on NASA TV. Since NASA TV is part of my daily diet of space media, I was very interested to see the newsroom, step in the auditorium where all the press conferences are held, and also talk with some of the people who work at NASA TV at Kennedy Space Center, or KSC TV as they call it, to find out about the work that they do, and also what it's like to provide some of the most unique and exciting coverage anywhere on — and off — the planet. I chatted with producers, directors, technicians and other people who work behind the scenes, plus I also had the good fortune to talk with one of the voices of NASA TV, George Diller.

Here are some of our conversations.

A Delta IV rocket rumbled and roared off launch pad 37B at Cape Canaveral Air Force Station in Florida Thursday evening, sending the GOES-P satellite soaring into a crisp and clear night sky. With liftoff at 6:57 p.m. EST, the rocket could be seen for several minutes after launch, and booster separation was clearly visible to observers on the NASA Causeway. The Geostationary Operational Environmental Satellite-P, or GOES-P, is the latest in a series of meteorological satellites designed to watch for storm development and weather conditions on Earth as well as detect hazards with its emergency beacon support and Search and Rescue Transponder. It will take ten days for the satellite to maneuver to its geostationary equatorial orbit at 35,888 km (22,300 miles). Once there, GOES-P will get a new name: GOES-15.

Scientists Come to a Conclusion: Asteroid Killed the Dinosaurs

Universe Today - Thu, 03/04/2010 - 6:38pm


Over the years, scientists have debated the cause of the mass extinction that wiped out the dinosaurs 65 million years ago. Now, a panel of 41 international experts says it's official: a massive asteroid around 15 kilometers wide slamming into Earth at Chicxulub, Mexico is the culprit. After surveying a wide variety of evidence for the competing theories, the panel said the telling evidence was the structures preserved in the interior of the crater. Computer models predicted how much rock was vaporized or ejected by the impact. "Our work lets us visualize the astonishing events of the few minutes after impact," said Dr. Penny Barton, who led the group. "The front of the asteroid hit the Earth while the far side was still out in the upper atmosphere, punching a hole though the Earth's atmosphere."
