Whoa. As many people noted on Twitter: Didn't see this one coming. Time Magazine named NASA's Ares rocket as the 2009 Invention of the Year. Ares beat out the what has been billed as the world's best paper airplane, the bladeless fan, rubber made from dandelions, and, my favorite, teleportation. I don't know who Time had for their judges, but obviously Buzz Aldrin wasn't among them. Check out his Huffington Post article where he says although the Ares I-X launched looked spectacular, Ares I needs to be scrapped.

Video Preview of Next Shuttle Mission

Nancy Atkinson — Thu, 12 Nov 2009 21:35:12 +0000

The next space shuttle mission STS-129, slated to launch next Monday Nov. 16, is a "spare parts and stock-up" mission. And the needed extra parts and supplies delivered to the International Space Station by Atlantis will mean spare years on the station’s life once the space shuttle fleet is retired. The mission is a landmark of sorts — not sure if it is a good landmark or bad — but STS-129 is scheduled to be the last space shuttle crew rotation flight. From here on out, crew rotation will be done by the Soyuz and any future commercial vehicle that may come online. Besides the crew, a payload of spiders and butterfly larvae will be on board Atlantis for an experiment that will be monitored by thousands of K-12 students across US. Find out more about the flight with a video preview of the mission, below.

Unusual Massive White Dwarf Stars Have Oxygen Atmospheres

Nancy Atkinson — Thu, 12 Nov 2009 21:14:40 +0000

White dwarfs are strange stars, but researchers recently discovered two of the strangest yet. However, these two oddballs are a missing link of sorts, between massive stars that end their lives as supernovae and small to medium sized stars that become white dwarfs. Somehow, these two once-massive stars avoided the core collapse of a supernova, and are the only two white dwarfs known to have oxygen-rich atmospheres. These so-called massive white dwarfs have been predicted, but never before observed.

Suborbital Could Be 'Next Big Thing' for Space Science

Nancy Atkinson — Thu, 12 Nov 2009 17:27:23 +0000

Upcoming commercial space flights are no longer only about rich, adventure-seeking space tourists. Researchers hope to capitalize on the prospect of quick, low-cost and frequent access to the micro-gravity environment of sub-orbital space. "We’ve got these great vehicles coming online and most of the discussion about them so far have centered on the tourism market," said Erika Wagner, member of SARG – the Suborbital Applications Researcher Group. "As researchers we felt this was a fantastic opportunity to do both science and education, as well."

Shedding Light on the Sun's "Lithium Mystery"

Nancy Atkinson — Wed, 11 Nov 2009 20:31:30 +0000

For decades, astronomers have known our Sun contains a low amount of lithium, while other solar-like stars actually have more. But they didn't know why. By looking at stars similar to the Sun to study this anomaly, scientists have now discovered of a trend: the majority of stars hosting planets possess less than 1% of the amount of lithium shown by most of the other stars. “The explanation of this 60 year-long puzzle is for us rather simple,” said Garik Israelian, lead author on a paper appearing in this week's edition of Nature. “The Sun lacks lithium because it has planets.”

This finding sheds light not only on the lack of lithium in our star, but also provides astronomers with a very efficient way of finding stars with planetary systems.

Up, Up and Away! Helium Balloon Telescope Explores the Sun

Nancy Atkinson — Wed, 11 Nov 2009 19:02:01 +0000

Exploring the Sun via helium balloon almost sounds like an adventure for an animated movie, but the SUNRISE balloon-borne telescope has captured data and images that show the complex interplay on the solar surface to a level of detail never before achieved. As in the video above, SUNRISE shows our local star to be a bubbling, boiling mass where packages of gas rise and sink, lending the sun its grainy surface structure. Dark spots appear and disappear, clouds of matter dart up – and behind the whole thing are the magnetic fields, the engines of it all.

Stunning Cassini Image to Knock Your Socks Off

Nancy Atkinson — Wed, 11 Nov 2009 14:07:26 +0000

What a way to start the day! This image is one of the first things I saw online this morning. The moon Rhea hangs like a pendant against Saturn and its rings. Amazingly, this is a raw image straight from Cassini; it has not been calibrated or enhanced in any way. This is art in its purest form and evidence of the phenomenal and enchanting beauty of the Saturn system, as well as confirmation of what an amazing spacecraft Cassini is.

Vatican Holds Conference on Extraterrestrial Life

Nicholos Wethington — Wed, 11 Nov 2009 03:31:39 +0000

Though it may seem an unlikely location to happen upon a conference on astrobiology, the Vatican recently held a "study week" of over 30 astronomers, biologists, geologists and religious leaders to discuss the question of the existence of extraterrestrials. This follows the statement made last year by the Pope's chief astronomer, Father Gabriel Funes, that the existence of extraterrestrials does not preclude a belief in God, and that it's a question to be explored by the Catholic Church. The event, put on by the Pontifical Academy of Sciences, took place at the Casina Pio IV on the Vatican grounds from November 6-11.(...)

Good News for Science News

Nancy Atkinson — Wed, 11 Nov 2009 01:32:20 +0000

Here's some refreshing news! In an era when mainstream media is cutting back on their science departments and science reporting, the Discovery Channel has just made an investment to step-up their science news with the re-launch of their new and improved news website, Discovery News. In the middle of it all is our very own Ian O'Neill, who is also the producer for Discovery News Space. The "new" part of Discovery News is that Ian's work on the space side is now integrated into a higher profile, redesigned news site. Ian and I had a chance to talk today about this good news for science news.

Bluffer's Guide to the Cosmos

The English language continually evolves. Just see Ambrose Bierce's definition of dictionary. New concepts call for new words that often evolve from a new dictum. Astronomy has made its fair share of contributions to this cause. But, Daniel Hudon's book "The Bluffer's Guide to: The Cosmos" belies such augmentations. Within, the language is as common and everyday as what you used around the gas pump or barber shop. Yet, the science and information is as exact and appropriate as needed to communicate an idea.

Finding the Mama Bear of Black Holes

Nancy Atkinson — Tue, 10 Nov 2009 18:22:19 +0000

While astronomers have studied both big and little black holes for decades, evidence for those middle-sized black holes has been much harder to come by. Now, astronomers at NASA's Goddard Space Flight Center in Greenbelt, Md., find that an X-ray source in galaxy NGC 5408 represents one of the best cases for a middleweight black hole to date. "Intermediate-mass black holes contain between 100 and 10,000 times the sun's mass," explained Tod Strohmayer, an astrophysicist at Goddard. "We observe the heavyweight black holes in the centers of galaxies and the lightweight ones orbiting stars in our own galaxy. But finding the 'tweeners' remains a challenge."

Great Observatories Combine for Stunning Look at Milky Way

Nancy Atkinson — Tue, 10 Nov 2009 17:33:58 +0000

All we can say is, "Wow!" In celebration of the International Year of Astronomy 2009, NASA's Great Observatories — the Hubble Space Telescope, the Spitzer Space Telescope, and the Chandra X-ray Observatory — have collaborated to produce an unprecedented image of the central region of our Milky Way galaxy. This is a never-before-seen view of the turbulent heart of our home galaxy. The image is being unveiled by NASA to commemorate the anniversary of when Galileo first turned his telescope to the heavens in 1609. NASA provided this image and the individual images taken by each of the Great Observatories to more than 150 planetariums, museums, nature centers, libraries, and schools across the country.

Hard-Luck Hayabusa In More Trouble

A problem-plagued Japanese mission to an asteroid just may have received its final blow. The Haybusa mission, which went to asteroid Itokawa in 2005 is currently trying to return to Earth, but now has suffered a breakdown in the third out of four ion thrusters. The cause was a voltage spike due to problems with a neutralization vessel, which previously caused the failure of two other thrusters. The fourth and only remaining thruster was shutdown earlier by engineers after signs that it also might succumb to high voltage damage. Engineers are now testing that engine, Thruster C, to determine if it is capable of long-duration firings. Hayabusa, which landed on Itokawa (possibly several times – mission managers aren't sure) might contain samples, but due to a malfunction of the sample collection device, JAXA has acknowledged that it cannot be sure Hayabusa actually managed to take samples from the surface of the asteroid.

A new module for the space station blasted off today from the Baikonur Cosmodrome, Kazakhstan at 9:22 a.m. EST. The Poisk (which means "explore" in Russian) is a combination docking module/airlock/future research module. It will meet up with the ISS on Thursday at 10:44 am. Poisk is the first permanent pressurized module to be added since May of 2008, when the Japanese "JEM" research module became part of the ISS, and is the first major Russian addition to the station since the Pirs docking compartment was launched in 2001. The new module will be used as an additional docking port for Russian vehicles, as an airlock for Russian-based spacewalks and as a platform for external science experiments.

Here are the first images of the Apollo 11 landing site since the Lunar Reconnaissance Orbiter dropped into its 50 km mapping orbit. The sun is almost straight overhead on this image so there's no real shadows visible. What's great about this image is that we can actually see the footpads on the Lunar Module from which Armstrong made his giant leap for mankind! See the closeup below for more details. The other great thing about this top image is that we get a good look at West Crater, which is the rocky area that Neil Armstrong saw as the LM neared the surface. The computer trajectory would have taken them right in the middle of that boulder field, so Armstrong flew manually to change the flight plan to fly westward to find a safe landing spot. This image is 742 meters wide (about 0.46 miles). North is towards the top of the image.

On the 75th anniversary of astronomer Carl Sagan's birth, the Planetary Society announced their plans to sail a spacecraft on sunlight alone by the end of 2010. Called LightSail, the project will launch three separate spacecraft over the course of several years, beginning with LightSail-1, which will demonstrate that sunlight alone can propel a spacecraft in Earth orbit. LightSails 2 and 3, will travel farther into space.

Sagan, co-founder of the Planetary Society was a long-time advocate of solar sailing.
