The new Kaspersky Internet Security is ready for release

I have participated in the beta testing of Kaspersky Internet Security 6.0 & been waiting for a long time for the following to happen: Finally we had reached the end of our testing cycles and development. Came about with the team, and decided to send this build for tech release. Although for widespread release, it is going to take some time (in the following month). Marketing and Sales departments will now work full force to promote this product. In the mean time, we are going to publish technical documents about the skinning engine. Also new builds for File-Servers and Workstations are on the way, which contain a lot of new and interesting features. Its a great product. They have not announced a date for the official release yet but you can visit Kaspersky.com in order to get more information. (Kaspersky has got a lot further with the application(s) then this screenshot anno 2000 make you believe...)

'My Life In The Bush Of Ghosts' enhanced & two tracks under a Creative Commons license for your remixing

One of my all time favorite albums 'My Life In The Bush Of Ghosts' (by David Byrne and Brian Eno anno 1981) has been remastered and is now being re-issued in a new package, with extensive liner notes and photos, and featuring 7 previously unreleased tracks from the original album and a film by influential artist Bruce Conner.
The idea to distribute two of the songs as multitracks under a Creative Commons license for your remixing pleasure is remarkably simple and a perfect fit for the spirit of these tracks.
This is the first time complete and total access to original tracks with remix and sampling possibilities have been officially offered on line. In keeping with the spirit of the original album,
Brian and David are offering for download all the multitracks on two of the songs. Through signing up to the user license, and in line with Creative Commons licenses, you are free to edit, remix, sample and mutilate these tracks however you like. Add them to your own song or create a new one. Visitors are welcome to post their mixes or songs that incorporate these audio files on the site for others to hear and rate.
The cd contains the following tracks of which no. 12-16 where not included on the original album: 1.America Is Waiting, 2.Mea Culpa, 3.Regiment, 4.Help Me Somebody, 5.The Jezebel Spirit, 6.Very, Very Hungry, 7.Moonlight In Glory, 8.The Carrier, 9.A Secret Life, 10.Come With Us, 11.Mountain Of Needles, 12.Pitch To Voltage, 13.Two Against Three, 14.Vocal Outtakes, 15.New Feet, 16.Defiant, 17.Number 8 Mix, 18.Solo Guitar With Tin Foil

Google patents free Wi-Fi

More evidence has emerged that Google is getting ready to blanket the U.S. with free Wi-Fi. Now, the company has filed for three patents related to offering wireless Internet access. Search Engine Roundtable points out that the patents all have to do with serving up advertising through a wireless Internet connection maintained by a third party, whose brand Google would include in the presentation of those ads. Sounds a lot like Google's latest plan to unwire San Francisco, where it has teamed up with EarthLink. By teaming up with partners who would build the actual Wi-Fi infrastructure, Google could complete a nationwide Wi-Fi network much more quickly than if it had to build it itself.
Google's Three Wireless Advertising Patent Applications is summarized as follows:
(1) Method and system to provide wireless access at a reduced rate:
Methods and system for providing wireless access at a reduced rate. In one embodiment, access to a WAP is provided to an end-user at a rate subsidized by a first entity. The first entity includes advertisements in an end-user view.

(2) Method and system to provide advertisements based on wireless access points:
Methods and system to provide advertisements in a view of an end user accessing a wireless access point. The advertisements are related to the WAP based on a predetermined criterion. This basically discusses the "integration" of the wireless ads into wireless enabled devices, their could be some geo specific ads as well discussed here.
(3) Method and system for dynamically modifying the appearance of browser screens on a client device:
In one embodiment, a connection of a client device to a wireless access point is identified. Further, the appearance of a screen presented on the client device is modified to reflect the brand associated with a provider of the wireless access point. This is basically about branding the ads with the WAP partner's logo and content.

So in short you have three patent applications from Google. One about optimizing the ads across wireless protocols. The second is about the integration of the ads and the third is about branding those ads.

AllOfmp3 releases AllTunes

AllofMP3 has released its latest desktop music library and download tool AllTunes. Although the name is an obvious play on iTunes, those farmiliar with AllofMP3 will know that they are infamous for extremely cheap, high quality and quasi-legal music downloads on the web. AllTunes is a windows desktop or smartphone interface to the AllofMP3 library, allowing users to find and download high quality music easily. The model is simple, download the application, signup for an account, find music (amongst the 45,000 albums they have) click and download. The price is 2c per megabyte downloaded, which works out to be around $0,9-1.40 per album, much better than the $0.99c a song at iTunes.
The reason the prices are so low is because AllofMP3 and AllTunes operate in Russia, where they claim to comply with all local copyright law and paying royalties back to artists and labels. The legality of the service has been questioned several times. The European Union & record industry has brought the AllofMP3 to court but has lost in all instances on their efforts to shut down the service. However customers from outside Russia(the United States, EU and possibly other countries) may be violating the law of their home country when using this service.
The catalog is very broad, You can also find some rare international music as well as all the usual classics. The preview feature is just awesome, it allows you to listen to a low-quality version of each song from within the player - not just a snippet but the full song (as long as you have credit in your account). For sophisticated audiophiles, AllTunes allows you to download your songs in a variety of codes and bitrates, from almost-lossless through to 64kbps mp3. AllofMP3 has been a service I have constantly used for years now, and AllTunes has made it even better. I am certain these guys get a lot of business, I hope that instead of being shut down it forces the record labels to re-think their pricing strategies.

Another roundup about AllOfmp3.com:
  • Pricing: By traffic - 20 US dollar for 1 gigabyte
  • Platform(s): AllTunes.com utility for PC & Smartphone or via Browser for all platforms
  • Downloading: Unlimited
  • Burning/Copying: Unlimited
  • Streaming: Samples
  • Format(s): MP3, Ogg Vorbis, MPC, Windows Media, MPEG-4, various lossless audio codecs
  • Digital Rights Management: None
  • Preview: Full-length at 24 kbit/s
  • Catalog: about 600,000 songs
  • Features: Guestbook for each artist, lyrics, charts, advanced search
  • Warning: This is a Russian site, which apparently complies with Russian law. Customers in other countries may be violating the law of their home country.

A Bird Flu Vaccine

A trial of an H5N1 bird flu vaccine has shown that this vaccine would probably be acceptable for licensure, if needed. However, the need for a vaccine with a total dose of 180 µg would pose a considerable barrier to rapid production of a supply that would be adequate to meet the world's requirements should a pandemic occur.
Like earlier trials with a similar preparation, the vaccine elicited a significant immune response only when given as two doses of 90 micrograms each. This is twelve times the amount needed in standard flu vaccines. And even that worked only in about half the people tested.

Because only limited amounts of vaccine virus can be grown in the short time available at the start of a pandemic, the smaller the dose needed to immunise someone, the more people can be vaccinated in time to benefit. Scientists are beginning to suspect that something about the chemical nature of the H5N1 surface proteins used in the vaccine, possibly the strategic placement of a sugar group, keeps the human immune system from responding as it usually does to flu proteins. Some teams are now investigating what might make the proteins more immunogenic. Read the original article here...

Computer games reduce pain

In my previous post 'Absence makes the heart grow weaker' I promised you more about wacky & useless studies (OK - I didn't use this wording but thats pretty much what I ment) and this one from New Scientist does the trick too:
Computer games can reduce pain, researchers say, and a high speed virtual death-match is more effective at dulling discomfort than an arcade classic like space invaders.
The discovery raises the prospect that trips to the dentist or painful injections could be made easier by providing patients with the right kind of computer game to distract them.
Bryan Raudenbush and colleagues at Wheeling Jesuit University in West Virginia, US, tested the effects of playing different genres of videogame on subjects receiving painful stimulus. They compared six genres of game - action, puzzle, arcade, fighting, sport, and boxing.
Half of the participants in the study were a total of 15 minutes to practice and play each game under normal conditions. Then one of their feet was placed in ice cold water and they were instructed to play for up to five minutes more. The control group underwent the same treatment but without having any computer games to play. On average, those subjects playing games were able to withstand the painful icy water for longer than the control group. Furthermore, those given sports or fighting games were able to withstand more pain than those playing any other genre.

Here's an Idea: Let Everyone Have Ideas

Like many top executives, James R. Lavoie and Joseph M. Marino keep a close eye on the stock market. But the two men, co-founders of Rite-Solutions, a software company that builds advanced — and highly classified — command-and-control systems for the Navy, don't worry much about Nasdaq or the New York Stock Exchange.
Instead, they focus on an internal market where any employee can propose that the company acquire a new technology, enter a new business or make an efficiency improvement. These proposals become stocks, complete with ticker symbols, discussion lists and e-mail alerts. Employees buy or sell the stocks, and prices change to reflect the sentiments of the company's engineers, computer scientists and project managers — as well as its marketers, accountants and even the receptionist.
"We're the founders, but we're far from the smartest people here," Mr. Lavoie, the chief executive, said during an interview at Rite-Solutions' headquarters outside Newport, R.I. "At most companies, especially technology companies, the most brilliant insights tend to come from people other than senior management. So we created a marketplace to harvest collective genius." That's a refreshing dose of humility from a successful C.E.O. with decades of experience in his field. (Mr. Lavoie, 59, is a Vietnam War veteran and an accomplished engineer who has devoted his career to military-oriented technologies.)
Most companies operate under the assumption that big ideas come from a few big brains: the inspired founder, the eccentric inventor, the visionary boss. But there's a fine line between individual genius and know-it-all arrogance. What happens when rivals become so numerous, when technologies move so quickly, that no corporate honcho can think of everything? Then it's time to invent a less top-down approach to innovation, to make it everybody's business to come up with great ideas.
That's a key lesson behind the rise of open source technology, most notably Linux. A ragtag army of programmers organized into groups, wrote computer code, made the code available for anyone to revise and, by competing and cooperating in a global community, reshaped the market for software. The brilliance of Linux as a model of innovation is that it is powered by the grass-roots brilliance of the thousands of programmers who created it. According to Tim O'Reilly, the founder and chief executive of O'Reilly Media, the computer book publisher, and an evangelist for open source technologies, creativity is no longer about which companies have the most visionary executives, but who has the most compelling "architecture of participation." That is, which companies make it easy, interesting and rewarding for a wide range of contributors to offer ideas, solve problems and improve products?
At Rite-Solutions, the architecture of participation is both businesslike and playful. Fifty-five stocks are listed on the company's internal market, which is called Mutual Fun. Each stock comes with a detailed description — called an expect-us, as opposed to a prospectus — and begins trading at a price of $10. Every employee gets $10,000 in "opinion money" to allocate among the offerings, and employees signal their enthusiasm by investing in a stock and, better yet, volunteering to work on the project. Volunteers share in the proceeds, in the form of real money, if the stock becomes a product or delivers savings.
Mr. Marino, 57, president of Rite-Solutions, says the market, which began in January 2005, has already paid big dividends. One of the earliest stocks (ticker symbol: VIEW) was a proposal to apply three-dimensional visualization technology, akin to video games, to help sailors and domestic-security personnel practice making decisions in emergency situations. Initially, Mr. Marino was unenthusiastic about the idea — "I'm not a joystick jockey" — but support among employees was overwhelming. Today, that product line, called Rite-View, accounts for 30 percent of total sales.
"Would this have happened if it were just up to the guys at the top?" Mr. Marino asked. "Absolutely not. But we could not ignore the fact that so many people were rallying around the idea. This system removes the terrible burden of us always having to be right."

Tastier Tomatoes in the Future?

Tomatoes are good for you. They strengthen the immune system and can prevent heart and circulatory disease. Now, researchers from the Max Planck Institute of Molecular Plant Physiology, in co-operation with Israeli scientists, have identified DNA fragments in tomatoes that make their contents both healthy and tasty. The researchers crossed wild tomatoes with cultured ones, then investigated the contents and genetic make-up of the hybrid. The results could allow tomato growers to use wild tomatoes to produce cultured tomatoes with the characteristics they desire (Nature Biotechnology, March 12, 2006). Tomatoes are a major nutrient for humans. In 2004, 120,000 tonnes of tomatoes were harvested worldwide - and every year this number increases. Numerous medical studies have shown the health value of tomatoes. Lycopen, the pigment that makes tomatoes red, can for example prevent heart disease. Tomatoes furthermore contain a lot of vitamins C and E, indispensable for human nourishment. But after centuries of cultivation for shape, colour, and other useful qualities, our cultured tomatoes today are of small genetic diversity, in comparison with wild types. This has affected the taste and health value of the fruits. To cultivate tomato strains with particular characteristics, researchers have to increase the genetic diversity of cultured tomatoes. This can be done either by cross-breeding them with wild tomatoes, or changing their genetic make-up technologically. Scientists from the Max Planck Institute for Molecular Plant Physiology in Golm, and their Israeli colleagues at Hebrew University in Jerusalem, chose the second option. They investigated strains of tomatoes created from the crossing of cultured and wild types. Their goal was to identify the biochemical composition of fruits and determine which factors control their development. The researchers’ findings could make it possible in the future to develop tomatoes in a targeted way to make them more nutritious & tasty. Read more about the tastiness of the future... ;-)

The past of Gene Hackman as an propagandist for Homeland Security unearthed by 'Conelrad'

A couple of years after his scene stealing performance as the piggish Norman in Robert Rossen's LILITH (1964) and mere months before his first Academy Award-nominated role as Buck Barrow in Arthur Penn's BONNIE AND CLYDE (1967), Gene Hackman brought his considerable, Broadway-honed acting skills to a 16mm, 22 minute U.S. government Civil Defense instructional film dynamically entitled COMMUNITY SHELTER PLANNING (1966). When Conelrad first learned of the existence of this film in 2000, we launched a no-holds-barred effort to locate it. After a six year search in which we annoyed scores of government archivists, public librarians and private film collectors, we are very pleased to announce that we have finally obtained a print of this elusive motion picture.
Unfortunately, our efforts to secure an interview with the film's star were unsuccessful. Mr. Hackman's agent at Creative Artists Agency, Fred Specktor, dismissed our formal request for such an opportunity by stating the following in a telephone call to Editor Bill Geerhart: "Gene really doesn't have time for this. It was a long time ago and it doesn't really matter to him anymore. Thanks for your interest."
Please read the full story at Conelrad, it is really fun.

Absence makes the heart grow weaker

Loneliness is bad for the heart, suggests a new study. It shows that loneliness increases the blood pressure of those nearing retirement age to the same degree as smoking or a sedentary lifestyle.
Chronic feelings of social isolation are associated with as much as a 30 mmHg rise in a person’s systolic blood pressure by the age of 65, which could easily push their systolic blood pressure over 150 mmHg, the medical definition of hypertension.
The study showed that this is independent of other confounding variables such as smoking, drinking, socioeconomic status and body mass index. “While we haven’t conclusively proven why this happens, the pieces are starting to fall into place,” says John Cacioppo, a psychologist at the University of Chicago, US, who conducted the research.
“This shows that how we deal with isolation changes as we age on both emotional and physical levels,” says Sarah Pressman, a health psychologist at Carnegie Mellon University. “This is not something that’s all in your head.” Read more...

Stanislaw Lem died at the age of 84

One of mine & Robin's favorite authors, one of the world's leading science-fiction writers Stanislaw Lem, died on Monday in his home city of Krakow at the age of 84.

Lem, whose books have sold more than 27 million copies and have been translated into more than 40 languages, won widespread acclaim for The Cyberiad, stories from a mechanical world ruled by robots, first published in English in 1974. Solaris, published in 1961 and set on an isolated space stations, was made into a film epic 10 years later by Russian director Andrei Tarkovsky and into a 2002 Hollywood remake shot by Steven Sodebergh and starring George Clooney. Lem, born on September 12, 1921 in what is now the Ukrainian city of Lviv, studied medicine before World War Two. After the war, communist censorship blocked the publication of his earliest writing. After the fall of communism in 1989 Lem ceased writing science-fiction, instead devoting himself to reports on near-future predictions for governments and organizations. He wrote essays on computer crime, as well as technological and ethical problems posed by the expansion of the Internet.

6 quotes of
Stanislaw Lem:
  • A dream will always triumph over reality, once it is given the chance.
  • Cannibals prefer those who have no spines.
  • Do not trust people. They are capable of greatness.
  • To torture a man you have to know his pleasures.
  • Where do consequences lead? Depends on the escort.
  • You climb to reach the summit, but once there, discover that all roads lead down.

Recruiting Robolobsters and Mind-Controlled Sharks.... Oh My!

March 23, 2006 -- From the use of war dogs and horses by the Romans to Hannibal's elephants to modern naval programs involving dolphins and beluga whales, animals have long played a role in mankind's feuds. In the quest to conquer the enemy, humans have looked to Mother Nature for help and inspiration for thousands of years. And today is no different. "Animals have been part of military operations since there have been military operations," said Noah Shachtman of DefenseTech.org. "They have been the fighting man's best friend for generations and in modern-day warfare that's still the case."

Mother Nature as Muse
When researchers at the Defense Advanced Research Projects Agency look for innovations to keep the U.S. military at the top of the technology heap, they need only look out their windows. "Over the centuries, biological systems have evolved unique capabilities to find a mate, find food, basically the things they need to do to sustain life," said Jan Walker, spokeswoman for DARPA. Walker said that the beings that walk, crawl, fly and swim across our planet have developed ways to survive and to accomplish tasks, and we can learn from them. "In some cases, biological systems have developed unique abilities," she said. "There's a beetle whose life cycle includes laying eggs in the bark of a burned tree. It has the ability to sense a forest fire from huge distances away so that it can get there to lay its eggs, and we want to know, how do they do that?" Though it may sound like science fiction, DARPA at one point sponsored research to understand more about how sharks detect things that don't belong in the water. "Sharks have a unique ability to track chemical plumes in the water," she explained. "We sponsored research that studied that ability, and so we implanted electrodes so that we could learn what part of the brain was active as the animal sensed the plume." DARPA doesn't talk too much about applications, but the idea of remote-controlled shark spies was widely reported as one possible application. Read more...

Skull discovery could fill gap between Homo Erectus & Homo Sapien

ADDIS ABABA (Reuters) - A hominid skull discovered in Ethiopia could fill the gap in the search for the origins of the human race, a scientist said on Friday.
The cranium, found near the city of Gawis, 500 km (300 miles) southeast of the capital Addis Ababa, is estimated to be 200,000 to 500,000 years old. The skull appeared "to be intermediate between the earlier Homo erectus and the later Homo sapiens," Sileshi Semaw, an Ethiopian research scientist at the Stone Age Institute at Indiana University, told a news conference in Addis Ababa. It was discovered two months ago in a small gully at the Gawis river drainage basin in Ethiopia's Afar region, southeast of the capital.
Sileshi said significant archaeological collections of stone tools and numerous fossil animals were also found at Gawis. "(It) opens a window into an intriguing and important period in the development of modern humans," Sileshi said. Over the last 50 years, Ethiopia has been a hot bed for archaeological discoveries.
Hadar, located near Gawis, is where in 1974 U.S. scientist Donald Johnson found the 3.2 million year old remains of "Lucy," described by scientists as one of the greatest archaeological discoveries in the world. Lucy is Ethiopia's world-acclaimed archaeological find. The discovery of the almost complete hominid skeleton was a landmark in the search for the origins of humanity. On the shores of what was formerly a lake in 1967, two Homo sapien skulls dating back 195,000 years were unearthed. The discovery pushed back the known date of mankind, suggesting that modern man and his older precursor existed side by side.
Sileshi said while different from a modern human, the braincase, upper face and jaw of the cranium have unmistakeable anatomical evidence that belong to human ancestry."The Gawis cranium provides us with the opportunity to look at the face of one of our ancestors," he added.

Giant Aldabra Tortoise Dies at Age 255

CALCUTTA, India, March 23 (UPI) -- Adwaitya the tortoise, once owned by the man whose British East India Company helped colonize India in the 18th century, has died at the age of 255. Adwaitya, or "The only one," was one of four giant Aldabra tortoises given to Robert Clive by British seamen who caught them in the Seychelles Islands, reports The Times of London. The other three died soon after they arrived in India. In recent years, Adwaitya had numerous illnesses. "Our records show the tortoise was born in 1750, but some have claimed he was born in 1705," said the Calcutta zoo's director. "Adwaitya, who delighted the zoo visitors for 131 years, died (Wednesday) morning. His shell will be preserved in the zoo." Clive, who became known as the "Conqueror of India," arrived in South Asia 1743 as a clerk in the East India Company. But it was his military skill that helped him lay the foundation for eventual British rule of India. Clive died in 1774.

High-Speed Surprise for Lying Eyes

By Ingrid Wickelgren
ScienceNOW Daily News
21 March 2006

The next time you drive in the fog, check your speedometer. You may be speeding and not know it. That's because--when the visual landscape lacks contrast--people perceive objects moving much slower than they actually are. A new study debuts the first convincing, quantitative explanation for this potentially dangerous visual mistake.In 1982, psychologist Peter Thompson of York University, United Kingdom, first noticed that when two objects of different contrast are moving at the same speed, people always say the higher contrast object is moving faster. Researchers brushed off this misperception, dubbed "the Thompson effect," as a kink in an otherwise precisely tuned visual machine. But a few years ago, Eero Simoncelli, a computational neuroscientist at New York University in New York City, and his colleagues wondered if they could explain this phenomenon using basic principles of human vision.
Simoncelli knew that the eye does not simply record light patterns like a camera does: Instead, what people see depends greatly on past experience (a cloud looks like a boat to one person and a truck to another, for example). So he and colleagues suspected that, when real information is sketchy (as it is in low-contrast situations), people rely even more heavily on their expectations. In a 2002 paper, the researchers used Bayesian statistics--a branch of mathematics that shows the ideal way to combine expectations with new information--to prove that this was indeed the case. It could also account for the Thompson effect, they argued.
Now Simoncelli and postdoc Alan Stocker have confirmed their theory with a real-life experiment. They asked each of five people to judge which of a pair of gratings on a computer screen appeared to be moving faster. Each person did this about 6000 times with the speed and contrast levels of the gratings changing from one trial to the next.
Stocker and Simoncelli then used Bayesian math to work backwards from each person's speed perceptions to determine what his or her expectations must have been. They confirmed that people expect slow movement over fast, and the team measured just how much more probable people expect slower speeds to be than faster ones. Simoncelli, whose findings appeared online Sunday in Nature Neuroscience, says that the findings might someday be used to devise better treatments for stroke victims who have trouble seeing motion or to build better driver-defense systems.
Matteo Carandini, a computational neuroscientist at Smith-Kettlewell Eye Research Institute in San Francisco, California, thinks the work's greatest import may be for basic research. "This opens the door” to finding the location of speed perception in the brain, he says.

How Whales Write Number One Hits

By Elizabeth Pennisi
ScienceNOW Daily News
22 March 2006

Humpback whales have long been celebrities for their intricate songs; tracks of their melodic moans, whistles, and clicks could fill a dozen CDs. How in the world do they do it? According to a new study, whales compose their ballads by stringing together these sounds into a grand series of repetitive patterns. Although the findings aren't proof of a cetacean language, they do indicate that the sea-faring giants use a kind of syntax, a feature thought to be unique to humans.Each year, male humpbacks devise new songs. And each year, a number one hit emerges that catches on among the whales. Because the songs are so complex, researchers have spent decades trying to figure out how whales compose new ones every year--and how they manage to remember them. One idea, first proposed 30 years ago, is that whale sounds are grouped into short units, which in turn form the components of longer phrases.
To test for such an underlying structure, Ryuji Suzuki, a neuroscience graduate student at the Massachusetts Institute of Technology in Cambridge, wrote a computer program to detect individual combinations of sounds. The program translates sound combinations into symbols--"AAABBB" or "ABACC", for example--that enable both the computer and human analysts to pick out specific patterns. Based on these patterns, the program derived "rules" of whale-song writing. The sets are arranged in a hierarchy of ever-larger repeating segments. It's a bit like human music: If you consider the seconds-long sets of whistles and clicks as musical notes, the notes combine into melodies, and the melodies into veritable sonatas, Suzuki and his colleagues report this month in the Journal of the Acoustical Society of America. This hierarchical structure allows for mixing and matching elements on several levels for easy repackaging and memorization of a tune, he says.
"What this tells me is that humpback whales have evolved a surprisingly sophisticated way of remembering the complexity of structure in their songs," says Phillip Clapham, a marine biologist at the National Marine Mammal Laboratory in Seattle, Washington. "The results challenge the idea that some of the properties of human language are unique to humans."

Hopping probe may hunt for ice on the moon

The entire future of human space exploration may rest on a patch of lunar ice. For the past two years NASA has focused on designing a new crew vehicle and launch system that could return astronauts to the moon by 2018. The agency's ultimate goal is to establish a permanent lunar base and use the program's technology to prepare a human mission to Mars. But the grand plan hinges on a risky prediction: that NASA will find water ice in a permanently shadowed crater basin at one of the moon's poles. Plentiful ice deposits would be a boon for lunar colonists, who could use the water for life support or convert it to hydrogen and oxygen rocket fuel. And two orbiters sent to the moon in the 1990s, Clementine and Lunar Prospector, found evidence of ice in perpetually shadowed polar areas where consistently frigid temperatures would preserve the water carried to the
