bfwebster writes "In a striking example of how a preliminary (but wrong!) scientific conclusion can persist for decades, Space.com has a story about how the south polar ice cap on Mars is mostly water, not mostly carbon dioxide (dry ice), as has been stated since the late 1960s. The new finding is based on analysis of Mars Observer readings that show that the souther polar ice cap is too warm at certain seasons to be dry ice. This finding has negative implications both for those claiming that liquid flow structures on Mars were caused by C02 instead of H20, as well as those who were hoping to use all that CO2 for terraforming."

They address suspected causes, foam, tile, and some of the alternatives had NASA known the ship would not be able to re-enter the atmosphere." viewstyle writes "PC Magazine has a pack of stuff put together on the space shuttle accident, as they recognized the fact that the space program inspired a lot of tech people in general. What's pretty cool is the section written by a guy there who worked on the computer components in the shuttle." And naturally, the idea of a space elevator is back in vogue again.

Thanks to all the readers who have sent links related to today's shuttle disaster. An Associated Press story carried on Salon says that an independent board (with members from the Air Force, Navy, Transportation Department and other federal agencies) has been appointed to investigate the disaster. CNN is carrying official statement from President Bush. Rediff.com has an article on the life of Indian astronaut Kalpana Chawla. borisonanovitch points to "more info on the science aboard Columbia and links to other NASA research." fabel reminds us "Most of the media is focusing on the slight damage that ocurred at takeoff (that NASA discounted at the time) but STS-107 was *delayed* for 6 months (original launch date 19 Jul 2003) Update: 02/01 23:51 GMT by T : [Note, should read "2002."] because of cracks in the propellant feed lines to the 3 main engines. A defect that could have caused catastrophic failure. Did the fix work or not?"

An anonymous reader writes "According to space.com, there are four new competitors in the X Prize competition. For those of you living under a rock, the X Prize competition is where people are competing for a 10 million dollar paycheck for creating a reusable spacecraft and using it twice within two weeks. X Prize officials are saying they expect to award the prize money within a year or two."

Slashback tonight with word on the (groan) fate of Iridium, more Speak n' Spell modding, examples of Serial ATA oozing to market, the RIAA versus mandatory DRM, and more. Read on for the updates.

In this household, we obey the laws of physics! Tuesday before last, we mentioned that two scientists had announced what they claim is the first accurate measure of the speed of gravity.

Now, Emperor_Alikar writes "In an article on Space.com, many physicists have criticized the current work on the speed of gravity, calling it 'nonsense' and 'simply incorrect.' Many of them still doubt the claims made by Fomalont and Kopeikin even before the results were even announced. Many of the physicists still hold on to the idea that gravity works instantaneously no matter what the distance, an idea that originated by Newton, but that was argued against by Einstein."

Back from the back from the back from the dead. Checkers writes "Spacedaily.com posted the following two stories about Iridium today. The first story is about the DoD committing the first of three renewal options that will use Iridium through 2005. The second story related story is about an agreement inked between Iridium and Harris Corp. that allows Iridium the right to use Harris' OS/COMET satellite command and control system for the life of the Iridium satellite network."

E.T. was also into this scene. In re: matt simpson writes "Another fantastic Speak & Spell modder is Dave Wright of the band "not breathing". You can check his work out, among other modifications to toys, at www.carrionsound.com Dave has made speak & spell/math/read for Nine Inch Nails, Meat Beat Manifesto, and many other bands. Figured you might be interested in other neat synth hackers :)"

Further evidence, never a good time to buy. SpinnerBait writes "It's seems like Serial ATA Controllers have been on the market forever but where have all the Serial ATA Hard Drives been? The wait seems to finally be over, as HotHardware shows with this review and showcase on a pair of new Seagate Barracuda V Serial ATA drives. This article covers benchmarks with the product in single drive configurations, as well as RAID 0. In addition, they show performance on two different SATA controllers, from Promise and Silicon Image. And oh, those nice thin neat little SATA cables! Gotta love 'em."

We've had a few articles about Serial ATA; I hope it lives up to its reputation.

Just to add to the confusion ... probejockey writes "A current article in the Globe and Mail claims SCO will start collecting licensing fees from some Linux users, not all Linux vendors as previously reported here."

Birds of a feather, separate rooms. Finally, Declan McCullagh sent in a few interesting links yesterday regarding the RIAA and its announced opposition to mandated DRM technologies:

"First, here are the photos from today's press conference.

Second, the supposed news of today's announcement was that the RIAA would no longer pursue mandatory-DRM technologies like the Hollings bill. But it was the MPAA that was behind Hollings from the beginning (September 2001). And when Hollings finally introduced his bill in March 2002, it was the MPAA that endorsed it, while the RIAA pointedly did not."

Thanks to Declan for the links.

Wasn't smart enough to get in, either ... Finally, thanks to the several readers who alerted me by email and in comments that the school variously rendered Cal Tech, CalTech and other things even worse is in fact properly spelled "Caltech."

The money is set to go to the non-profit Astronomical Society of the Pacific (ASP). Looks like they're billing this as Astronomy's version of Lance Bass and the Space Station. How much would YOU pay?"

fjordboy writes "The star Rho Cas, which can be seen by the naked eye from the Northern Hemisphere, is showing signs that it may be exploding in the near future. Rho exploded in 2000, creating a cloud of gas over 10,000 times the size of earth (which isn't all that large in space scales), however, the same star is showing signs of collapsing which may point to a much larger explosion in the near future, which should be large enough to be seen by backyard astronomers with little to no specialized equipment.

LoPingHo writes "Scientists have found a ring of stars around our galaxy that has previously been undetected due to the faintness of the stars. The article says that it only amounts to 1% of the galaxies mass, but if they are just now finding those, that means there could be even fainter ones there too. Could this be part of the elusive 'dark matter' talked about so much lately?"

Makarand writes "In a study published recently in the journal Science, a team of researchers say that they are 95% sure the universe is between 11.2 billion and 20 billion years old according to this article on Space.com. The new calculations from cosmologists at Case Western Reserve University and Dartmouth College involved new information about old star clusters in our galaxy and a better understanding of how stars evolve." Which blows my theory that the Universe is predated by Zsa Zsa Gabor, but oh well.

Joe Jordan writes "Space.com is advertising the Top 10 Space Mysteries for 2003, and perhaps for all time, given the current rate of discovery." Some of them are obvious, like the origin of life, and the possibility of alien life forms, but the list is still a good compilation of space's greatest questions.

DarkKnightRadick writes "Here you can find what Space.com considers the Top 10 Space Science images of the past year." As the accompanying article points out, "Hubble, refurbished during 2002, continues to provide benchmark astrophotography. However, other telescopes, in space and on the ground, see things that Hubble cannot." DarkKnightRadick continues: "The site is filled with artists theoretical renderings and actual photographs from both ground and space based telescopes."

Woogiemonger writes "To commemorate the 200 year anniversary of the Lewis & Clark expedition, NASA and other researchers are using satellite and aircraft remote-sensing technology to accurately reconstruct the path of the Lewis & Clark expedition, down to the precise location of each encampment. Considering many parts of the landscape along the path may have changed dramatically, this is no easy task. The final result will be a 3D interactive map publicly available on the WWW."

gilgsn writes "Yahoo has an article from space.com about a satellite which will be operated by FTP over TCP/IP on the Internet! The CHIP (Cosmic Hot Interstellar Plasma Spectrometer) spacecraft will examine the stuff between stars, the so-called void of space that is actually rich with hot gas. The choice of protocol was dictated by economics. I wonder what OS it will run and if communications will be encrypted?"

rehannan writes "Saturn is now a mere 750 million miles from earth; the closest point in it's 30-year orbit. Saturn's rings are facing earth this time around, which should make for some pretty good views. For more details, check out Space.com or the CNN article."

Target Practice writes "Is it an asteroid? Is it a comet? Who cares? According to Sky and Telescope's website, 3200 Phaethon has been spewing chunks into our atmosphere for the past 150 years, and tonight, after the lan party, you can step outside at two or three A.M. and see the best light show yet - topping off at 75 meteors per hour! Be there..." Space.com has another story.

Heartbreak writes "According to 'Last Wake-Up Calls to CONTOUR', mission operators at Johns Hopkins University Applied Physics Laboratory will try for the last time to contact whatever is left of NASA's CONTOUR comet probe next week. In case you've forgotten, the probe never checked in after its escape burn in August. A leading theory for the failure is that the solid-fuel booster engine (mostly buried in the body of the probe) exploded near the end of its burn. They will probably never be certain about what happened, since the burn occurred while the probe was out of contact with ground stations. Astronomers later found three objects near the expected course of the probe, presumably its remains. The plan of action for the attempted contact---aim for the biggest piece."

Cujo writes "This article in space.com discusses what the actual costs of the space station have been since it was first proposed by President Reagan in 1984. Depending on how you account for the cost of shuttle launches, the number is well over $40 billion in the U.S. alone. It begs the question of what else could have been done with the same money and far superior management."

XNormal writes "Elon Musk, founder of Zip2 and PayPal is planning to build a launcher for small satellites. Much of his personal fortune come from the IPO of PayPal and subsequent sale to eBay. The amount of money he plans to spend on this project is not much more than Denis Tito spent on his space station visit. The difference is that this venture actually tries to do something productive. Elon is also behind the Life to Mars mission."

Earendi1 writes "Space.com has an article indicating that it's possible to "listen" to the Leonid meteor shower on radio and television. Basically, it explains that meteors can cause reception of weak, distant radio stations in the FM band and TV stations between channels 2 & 6."

Astronomers predict that the height of the storm over North America in 2002 could possibly generate 40 meteors every minute -- over 2,400 per hour!' Space.com has plenty of information available. I wanted to submit it early so you could plan ahead. It'd make for a long work or school day, but it's not something I'd care to miss."

HobbySpacer writes "At this week's 1st Int. Symposium on Beamed Energy Propulsion in Huntsville a wide range of laser and microwave propulsion schemes are being presented. The big news so far is the announcement by Gregory Benford of plans for a test of microwave propulsion with the Cosmos Sail, due to fly early next year. The possibilities of using lasers to deflect incoming asteroids & comets are also under discussion."

RedWolves2 writes "Today is ISS's second anniversary of Operations. Two years ago today NASA astronaut Bill Shepherd and Russian cosmonauts Yuri Gidzenko and Sergei Krikalev first boarded the ISS. In two years the station has grown to more then 200,000 pounds and has had 112 visitors."

sckienle writes "Space.com has an article on using anti-matter for propulsion in space. It isn't true Star Trek warp stuff, in fact it is a variation on an fusion based pellet design I saw in the late 70's, but interesting concept. The concept is still somewhat of a dream, as stated in the article: 'The real hub is the storage [of antimatter]. There's a lot of technology between here and there.' Later on it also mentions that we can't produce a lot of antimatter efficiently yet. Still it might be worth the effort if the theoretical acceleration proves out." The BBC has a story about studying antimatter in a lab.

Apparition writes "CNN is reporting that the star at the center of our galaxy is actually a super-massive black hole. The article then claims that it occupies a volume of space about 3 times that of our solar system. If my math is correct, about 230 million suns could fit into that same volume, so it doesn't impress me that the claimed mass of the black hole is only between 2.6 and 3.7 million times that of the sun. So what is up here? Since when do black holes occupy so much space (I thought they were points)? And how can something with a density only 1/100 of our Sun be called super-massive?" I think the article is talking about a maximum possible size of the object, due to limitations on the resolution of our instruments. Nature has a no-registration story about the research. Update: 10/16 23:44 GMT by M : There's an article with more information on space.com, and a press release from the European Southern Observatory.

Illuminati Member writes "Space.com has an article that shows off new, high quality pictures, from the Mars Global Surveyor, that shows what Inca City truely is. In 1972 the Mariner 9 took some snapshots of Mars and one picture showed ridges formed in a peculier manner. This was eventually dubbed 'inca city' for its unusual formation. Now, the MGS has given us the true picture of this anomaly. Interesting thing was how the formations could possibly be more proof of the existance of water. The intensity as the picture was beamed to us from the satellite was high, and the excitment at what it showed was grand."

Professor_Quail writes "Space.com reports that SETI@home is planning to transfer it's operations from Arecibo to another telescope in Australia, where they say lies an increased chance of finding extra-terrestrials. The Australian telescope is more powerful, with a wider view of the sky; scientists are betting that this new telescope will also help find signs of 'shriveling' black holes."

An anonymous reader writes "Five years ago today, on September 27, 1997, NASA and the Jet Propulsion Laboratory began to lose communication with the Mars Pathfinder and ended its highly successful mission. The interview with Matt Golombek, Project Scientist, highlights Mars' warm and wet past. The still remarkable landing sequence, with first signal only 3 minutes after touchdown, seemed a rare combination of luck (bounced 16 times and landed on its base petal). Not mentioned, it cost less than the making of even a medium-sized Hollywood movie." NASA is getting ready to publish their future plans for deep-space missions.

MojoT writes "There's an interesting piece over at Space.com regarding the current renewed interest in returning to the Moon. Quoting: 'Earth's scuffed up and trampled Moon is once again targeted for high- tech visitors. Robotic spacecraft from several nations, as well as NASA and the U.S. Department of Defense, will be first to chalk up lunar return mileage.'"

tetrad writes "The BBC reports that a new object has been discovered orbiting Earth. It's possible that it's just a piece of space junk, but more likely it is a rock that has been recently (in the last year) captured by our planet's gravitational field. If the object is confirmed to be natural, this would be Earth's third moon. (Did you know there were two already?)" Here's our earlier mention of Earth's alleged second moon. Update: 09/12 04:52 GMT by T : Reader cscx adds a link to an article running on space.com which says this newfound object may be some trash from the Apollo missions.

An anonymous reader writes "The computer system that launches the Space Shuttle is an old, but important, computer system. It is built from mid 70's technology and features SSI chips like 7400's...which are getting hard to find. It has 64k of memory and no room to repair any software bugs. NASA started the CLCS project in 1996 which uses state of the art computer languages, OO methodologies, and hardware. Everything that you could actually hire people off the street for. However, NASA is in a budget crunch with the Space Station cost overruns. It is looking to trim costs to keep the Space Station going. There are stories about CLCS getting cancelled here and these guys say its already cancelled."

ke4roh writes "NASA reports that they're readying Atlantis for a launch "no earlier than October 2". STS-112, space station assembly flight 9A (the 15th) will add to the truss on the station. To get the station from the vehicle assembly building to the launch pad, they transport it in launch position - on one of the 37-year-old crawlers that travels at just 1 mile per hour. Each 6 million pound vehicle transports a big rectangle - the Mobile Launch Platform - to the launch pad. The crawler is 40 by 37 meters, has two steering wheels and two mufflers the size of a car. The crawlers have received minimal service to date, and an inspector noticed a cracked bearing shortly before a crawler took Atlantis out for the launch. A few folks are enjoying the opportunity to work on the crawlers before they make their journey. Will N-Sync's 23-year-old singer Lance Bass be space tourist number three - and the youngest person to ever fly in space? Corporate sponsors get to decide. Telescopes show Contour, short for "Comet Nucleus Tour", in three pieces. Unfortunately, it's only supposed to be one. The craft was to visit three comets to investigate their contents. They're murmuring about a replacement which would cost about $15M less (than the $154M price tag) thanks to much of the engineering being done already. The AP has more."

tanveer1979 writes "Space.com has an interesting photo feature from the voyager craft. For the uninformed voyager is the most distant man made object. For the first time we are recieving photos of distant parts of the solar system. Currently voyager is about 12 light hours away. Wonder how far is that? Well Sun is 8 light minutes away from Earth. In case you are wondering what is this all about, check out the current location of voyager. The voyager spacecraft are about to cross heliopause, which is the limit of the rule of the sun, after which inter steller winds take over, and for the first time scientists can get the feel of what lies outside the solar system."

finally writes "Space elevator news is being reported on Space.com and Yahoo. I, for one, am really excited about the project. I was wondering if any of the broad range of talents and skills that we have here have thought of doing a sort of open source assistance to this project by means of donating time and knowledge." We did a big story last week on this space elevator conference.

At its peak as many as 60 or more shooting stars can be visible per hour from the Northern Hemisphere. This year's viewing should be especially good since the 'Earth is expected to encounter the core of the Perseid swarm, where meteoroid concentration is densest, next Monday.'
