NASA Mars 'Returner'

Curiosity is making amazing progress even as we dawdle on Facebook right now. Just earlier this week, it discovered sediment that mimics deposits of what an Earth stream would leave if it were there on Mars. Hopefully this is the sort of discovery that might precede discovering remnants of microbial, or even advanced life (or even currently living organisms!).

The sad thing is that those potential samples are still anywhere between 36 - 250 million miles away (depending on orbital comparisons) from Earth. A mild hindrance for us in investigating these sedimentary samples, and even any biological samples, under clean-room laboratory conditions befitting of the potential discoveries.

This can all change in the very near-future thanks to some provisional mission plans from the great minds at NASA...

NASA's Mars Program Planning Group released on Tuesday (25th September 2012) several key mechanisms that could be employed in order to bring samples of sediment, strata and even bio-matter back to Earth for analysis and study!

Out of these options laid out, NASA have decided upon one, but refuse to commit pen to the proverbial paper until the Whitehouse release their 2014 fiscal year budget request.

One such mechanism involves the use of containment tubes, sealed several times over to protect against deep-space. These are then mounted into a supersonic rocket which relays the samples to an orbiting base-station.
Much like a carrier-pigeon, this station then passes the projectile into a larger vessel, which is propelled towards Earth. Once in proximity to Earth, it will be collected by a human-manned craft and brought down to the planet for investigation.
Quite literally a shuttle relay run!

Other options involve the use of Sky-cranes, much like how Curiosity was delivered, which drop off several collection robots which continually collect and deliver specimens.

The key thoughts and considerations here are that Mars is now potentially being 'contaminated' by Earth - what is to say that bacteria wasn't present in Curiosity or the Rover? Similarly, what is to say that specimens brought back from Mars are able to be controlled through our known methods of decontamination and bio-hazard procedures in laboratories?

Would it not be a stroke of irony, if not typical human-luck, that a newly discovered bacterium from Mars wipes out our planet, simply because we are not adapted to combat it? Well, NASA may be able to use the International Space Station to study the samples within, so we may be safe...

Water on Mars: NASA scientists are 'excited'

Mars rover Curiosity found rocks on the Martian surface that are too big to be carried by wind, so researchers suppose water must have existed on Mars at one time. Over the next two years, Curiosity will continue its search for signs of ancient microbial life on Mars.

There have been previous signs that water existed on the red planet long ago, but the images released Thursday showing pebbles rounded off, likely by water, offered the most convincing evidence so far of an ancient streambed.
There was "a vigorous flow on the surface of Mars," said chief scientist John Grotzinger of the California Institute of Technology. "We're really excited about this."

The discovery did not come as a complete surprise. NASA decided to plunk Curiosity down inside Gale Crater near the Martian equator because photos from space hinted that the spot possessed a watery past. The six-wheeled rover safely landed Aug. 5 after a nail-biting plunge through the Martian atmosphere. It's on a two-year, $2.5 billion mission to study whether the Martian environment could have been favorable for microbial life.
Present day Mars is a frozen desert with no hint of water on its radiation-scarred surface, but geological studies of rocks by previous missions suggest the planet was warmer and wetter once upon a time.
The latest evidence came from photos that Curiosity took revealing rounded pebbles and gravel — a sign that the rocks were transported long distances by water and smoothed out.
The size of the rocks — ranging from a sand grain to a golf ball — indicates that they could not have been carried by wind, said mission scientist Rebecca Williams of the Planetary Science Institute in Tucson, Ariz.
Though Curiosity did not use its high-tech instruments to drill into the rocks or analyze their chemical makeup, Grotzinger said scientists were sure that water played a role based on just studying the pictures.
It's unclear how long the water persisted on the surface, but it easily could have lasted "thousands to millions of years," said mission scientist Bill Dietrich of the University of California, Berkeley.
Curiosity chanced upon the dried-up streambed while driving to Glenelg, an intriguing spot where three types of terrain meet. Its ultimate destination is Mount Sharp, a mountain rising from the center of crater floor, but it was not expected to travel there until the end of the year.
Finding past water is a first step toward learning whether the environment could have supported microbes. Scientists generally agree that besides water and an energy source such as the sun, organic carbon is a necessary prerequisite for life.
While an ancient streambed holds promise as a potentially habitable environment, scientists don't think it's a good place to preserve the carbon building blocks of life. That's why the rover will continue its trek to the foothills of Mount Sharp where there's a better chance of finding organics.

Dyson Spheres: The Ultimate Energy Shell Game

 The world's exponential population growth will soon need to flatten out otherwise within a few hundred years every square foot of the Earth's surface will be taken up by a human. (Which reminds me of one of my favorite bumper stickers from a space advocacy group in the 1970s that read: "American Needs Space to Grow.")
With this population growth, mankind's hunger for energy has also increased exponentially. And if this continues, we will soon consume more energy than the Earth receives from the sun. Should they exist, this could be a common problem faced by burgeoning civilizations across the galaxy.
ANALYSIS: Looking for Alien 'Bubbles' in Other Galaxies
A solution to this energy demand is to become an extra-terrestrial civilization and harvest the resources of a planetary system to colonize space. A daunting yet logical step is to build solar energy-collecting structures in space and live on them.
This concept was taken to its logical extreme by British physicist Freeman Dyson who proposed in 1959 that advanced extraterrestrial civilizations might encase their stars in an artificially constructed sphere, the radius of Earth's orbit.
This so-called Dyson Sphere would provide a virtually infinite living space 600 million times larger than the surface area of the Earth. It would also trap almost all of the sun's energy output -- 400 trillion trillion watts!
Dyson was inspired by descriptions of such mega structures in two science fiction stories: "The Star Maker" by Olaf Stapledon, written in 1937, and "The World, the Flesh, and the Devil," written by scientist John Desmond Bernal in 1929. The later story describes a "Bernal Sphere" space habitat.
A rigid shell of the Dyson sphere might have a thickness of a few feet, depending on the strength of the material fabricated. It would also have to rotate to make artificial gravity. To maintain habitable temperatures the sphere would need to be bigger than Earth's orbit.
ANALYSIS: Super-Civilizations Might Live Off Black Holes
To avoid the dynamical stress a solid shell might undergo, a Dyson Sphere might be a constellation of many small independently orbiting structures -- like squares of mirrored glass on a disco ball. The energy-collecting elements would likely be very thin, while habitat segments would be thicker. Their orbital paths would be adjusted by using solar sails or ion engines.
The classic science fiction story "Ringworld" By Larry Niven, meticulously describes a spinning Hula-Hoop type structure, rather than a sphere as imagined by Dyson.
At least a partial Dyson Sphere -- or Niven's ring -- around the sun could be built from dismantling the planet Mercury and reassembling it into shell segments. The problem is that the energy required for destroying a planet is 100 billion times the U.S. annual energy consumption (sheesh! Even the Death Star probably didn't carry those kinds of batteries!).
So where would that energy come from? The sphere would have to be built piecemeal with the energy collected from the first segments being use to fuel further planetary disassembly.
ANALYSIS: Why We Don’t Need to Worry About Space Invaders
An army of robots would have to do the task. They would need to use resources to build more robots -- like the enchanted brooms in Walt Disney animation of Paul Dukas' symphonic poem "The Sorcerer's Apprentice." Even with this bootstrapping approach, the construction would take centuries because orbiting solar collectors can only capture so much energy over time.
There have already been astronomical database searches for Dyson spheres. The spheres would absorb and re-radiate the star’s energy as infrared light. As seen from Earth, a shell or partial shell would glow at a comparatively cool few hundred degrees Fahrenheit.
Galactic archeology is now being done by scouring infrared all-sky databases for sources in this temperature range. An artificial structure would need some other clues, perhaps an unusual spectral signature not found in a dust-shrouded young stellar object, or a complex, repeating fluctuation in brightness that is hard to explain by normal circumstellar dynamics.
Finding unequivocal evidence for a Dyson Sphere would tell us that there are no practical limits to the capabilities of an intelligent species, given time, perseverance, and a godlike mastery over matter and energy.

Quantum Computing

News #1:

An important step towards creating humanity's first Quantum Computer has just been made public, after being undertaken by Australian researchers earlier this year.

As you may be aware  there are huge inroads being made towards developing the next generation of super computer. Whilst there are other variations, the one we are concerned with the most, is the Quantum Computer.

Current scientists have faced huge problems - firstly in the fabrication of a stable base for a Quantum Computer to exist from, the isolation of the qubits, but also in the avoidance of certain unfortunate side-effects of Quantum behaviour - Quantum Decoherance.

As previously mentioned, Quantum Decoherance is where the 'computation' is lost to the localised environment. Physically, this could be external influence (poor isolation of source), the electrons being relocated outside of the 'CPU' wafer or other far more complex quirks of quantum interactions.

The research team in Australia's University of New South Wales have managed to make substantial progress down the Quantum route however by managing to bind phosphorus atoms into a piece of silicon wafer used in the Quantum Computer assembly. The key difference here is that the traditional Quantum Computer was always assumed to use a vacuum to store the superposition - however as stated above, this leads to the particles having the freedom to leave the computation area; whilst this procedure essentially stores and retains the particles within the silicon wafer - making for a more stable and controlled environment.

You can read more about this article here: http://www.abc.net.au/science/articles/2012/09/20/3593847.htm

News #2:

Whilst silicon has been explored by Australian researchers (as above), another team are experimenting using Diamond. The beauty with Diamond in Quantum Computing is that it is never 100% pure. There will always be unwanted atoms of other elements present within it's crystalline structure which devalue the Diamond and detract from it's appeal. This is the key area that makes Diamond so useful to Quantum researchers though!

Having a rogue atom suspended in Diamond is a huge bonus, as the particle will be held in place by the Carbon of the Diamond, minimising on Decoherance. Plus, what an amazingly robust processor - a Diamond chip; who knows what could be done with such a component if it went mainstream!

Testing so far has revealed that Diamond Quantum Computers can retain data for 1.4secs before losing the information; currently only at room temperature. Cooling down to near-absolute freezing would allow the particles to slow down to an extent that they would be able to store data (i.e. with minimal movement) for vastly extended periods of time.

Occupy Mars: History of Robotic Red Planet Missions

Every 26 months there is an opportunity to send a vehicle from Earth to the planet Mars along an efficient, low-energy trajectory. The trip can take six months or more. Probes to Mars often fail; as of July 2012, the success rate was 47 percent.
The Soviet Union was first to attempt to send unmanned space probes to Mars. Several failed, but in 1971 the lander Mars 2 became the first object from Earth to reach the surface of the Red Planet. Unfortunately Mars 2 crashed rather than landing softly. Its sister probe, Mars 3, did manage to land on Dec. 2, 1971. The Mars 3 lander transmitted data for a few seconds before falling silent.
The first truly successful Mars surface probes were the Viking 1 and 2 landers, sent from the United States, which touched down in 1976. The landers gathered soil samples for analysis using their robotic arms, and they thoroughly photographed the area surrounding their landing sites.
Another milestone was reached in 1997, when the Mars Pathfinder was landed by the United States. Pathfinder released a tiny remote-controlled rover, called Sojourner, which explored the Martian surface for nearly three months before contact was lost.

The Theory of Special relativity and Time Travel.

Time travel is one of my favorite topics! I have posted some time travel concepts before on this very page, and I have continued to study this fascinating concept as the time have passed by.

We all travel in time. During the last year, I've moved forward one year and so have you. Another way to say that is that we travel in time at the rate of 1 hour per hour.

But the question is, can we travel in time faster or slower than "1 hour per hour"? Or can we actually travel backward in time, going back, say 2 hours per hour, or 10 or 100 years per hour?

It is mind-boggling to think about time travel. What if you went back in time and prevented your father and mother from meeting? You would prevent yourself from ever having been born! But then if you hadn't been born, you could not have gone back in time to prevent them from meeting.
Albert Einstein

The great 20th century scientist Albert Einstein developed a theory called Special Relativity. The ideas of Special Relativity are very hard to imagine because they aren't about what we experience in everyday life, but scientists have confirmed them. This theory says that space and time are really aspects of the same thing—space-time. There's a speed limit of 300,000 kilometers per second (or 186,000 miles per second) for anything that travels through space-time, and light always travels the speed limit through empty space.

Special Relativity also says that a surprising thing happens when you move through space-time, especially when your speed relative to other objects is close to the speed of light. Time goes slower for you than for the people you left behind. You won't notice this effect until you return to those stationary people.

Say you were 15 years old when you left Earth in a spacecraft traveling at about 99.5% of the speed of light (which is much faster than we can achieve now), and celebrated only five birthdays during your space voyage. When you get home at the age of 20, you would find that all your classmates were 65 years old, retired, and enjoying their grandchildren! Because time passed more slowly for you, you will have experienced only five years of life, while your classmates will have experienced a full 50 years.

Time traveler

So, if your journey began in 2003, it would have taken you only 5 years to travel to the year 2053, whereas it would have taken all of your friends 50 years. In a sense, this means you have been time traveling. This is a way of going to the future at a rate faster than 1 hour per hour.

Time travel of a sort also occurs for objects in gravitational fields. Einstein had another remarkable theory called General Relativity, which predicts that time passes more slowly for objects in gravitational fields (like here on Earth) than for objects far from such fields. So there are all kinds of space and time distortions near black holes, where the gravity can be very intense.

In the past few years, some scientists have used those distortions in space-time to think of possible ways time machines could work. Some like the idea of "worm holes," which may be shortcuts through space-time. This and other ideas are wonderfully interesting, but we don't know at this point whether they are possible for real objects. Still the ideas are based on good, solid science. In all time travel theories allowed by real science, there is no way a traveler can go back in time to before the time machine was built.

I am confident time travel into the future is possible, but we would need to develop some very advanced technology to do it. We could travel 10,000 years into the future and age only 1 year during that journey. However, such a trip would consume an extraordinary amount of energy. Time travel to the past is more difficult. We do not understand the science as well.

Actually, scientists and engineers who plan and operate some space missions must account for the time distortions that occur because of both General and Special Relativity. These effects are far too small to matter in most human terms or even over a human lifetime. However, very tiny fractions of a second do matter for the precise work necessary to fly spacecraft throughout the solar system.

Have Aliens Left The Universe?

Recently, renowned scientist Stephen Hawking stated that he too believes aliens exist: “To my mathematical brain, the numbers alone make thinking about aliens perfectly rational.”

Hawking thinks we should be cautious about interacting with aliens — that they might raid Earth’s resources, take our ores, and then move on like pirates. “I imagine they might exist in massive ships, having used up all the resources from their home planet. Such advanced aliens would perhaps become nomads, looking to conquer and colonize whatever planets they can reach.”

But where are they all anyhow?

For years, NASA and others have been searching for extraterrestrial intelligence. The universe is 13.7 billion years old and contains some 10 billion trillion stars. Surely, in this lapse of suns, advanced life would have evolved if it were possible. Yet despite half a century of scanning the sky, astronomers have failed to find any evidence of life or to pick up any of the interstellar radio signals that our great antennas should be able to easily detect.

Some scientists point to the “Fermi Paradox,” noting that extraterrestrials should have had plenty of time to colonize the entire galaxy but that perhaps they’ve blown themselves up. It’s conceivable the problem is more fundamental and that the answer has to do with the evolutionary course of life itself.

Look at the plants in your backyard. What are they but a stem with roots and leaves bringing nutriments to the organism? After billions of years of evolution, it was inevitable life would acquire the ability to locomote, to hunt and see, to protect itself from competitors. Observe the ants in the woodpile — they can engage in combat just as resolutely as humans. Our guns and ICBM are merely the mandibles of a cleverer ant. The effort for self-preservation is vague and varied. But when we’ve overcome our struggles, what do we do next? Build taller and more splendid houses?

What happens after life completes its transition to perfection? Perhaps across space, more advanced intelligences have taken the next evolutionary step. Perhaps they’ve evolved beyond the three dimensions we vertebrates know. A new theory — Biocentrism — tells us that space and time aren’t physical matrices, but simply tools our mind uses to put everything together. These algorithms are the key to consciousness, and why space and time — indeed the properties of matter itself — are relative to the observer. More advanced civilizations would surely understand these algorithms well enough to create realities that we can’t even imagine, and to have expanded beyond our corporeal cage.

Like breathing, we take for granted how our mind puts everything together. I can recall a dream I had of a flying saucer landing in Times Square. It was so real it took awhile to convince myself that it was a dream (that I was actually at home in bed). I was standing in a crowd surrounded by skyscrapers when a massive spaceship appeared overhead. Everyone started running. My mind had somehow generated this spatio-temporal experience out of electrochemical information. I could feel the vibrations under my feet as the ship started to land, merging this 3D world with my inner thoughts and sensations.

Although I was in bed with my eyes closed, I was able to run and move my arms and fingers. My mind had created a fully functioning body and placed it in a virtual world (replete with clouds in the sky and the Sun) that was indistinguishable from the one I’m in right now. Life as we know it is defined by this spatial-temporal logic, which traps us in the universe of up and down. But like my dream, quantum theory confirms that the properties of particles in the “real” world are also observer-determined.

Other information systems surely exist that correspond to other physical realities, universes based on logic completely different from ours and not based on space and time as we know it. In fact, the simplest invertebrates may only experience existence in one dimension of space. Evolutionary biology suggests life has progressed from a one dimensional reality, to two dimensions to three dimensions, and there’s no scientific reason to think that the evolution of life stops there.

Advanced civilizations would certainly have changed the algorithms so that instead of being trapped in the linear dimensions we find ourselves in, their consciousness moves through the multiverse and beyond. Why would Aliens build massive ships and spend thousands of years to colonize planetary systems (most of which are probably useless and barren), when they could simply tinker with the algorithms and get whatever they want?

Life on Earth is just beginning to send its shoots upward into the heavens. We’ve even flung a piece of metal outside the solar system. Affixed to the spacecraft is a record with greetings in 60 languages. One can’t but wonder whether some civilization more advanced than ours will come upon it. Or will it just drift across the gulf of space? To me the answer is clear. But in case I’m wrong, I have a pitch fork guarding the ore in my backyard.

Nexi robot

Nexi robot helps Northeastern University track effects of shifty body language (video)

MIT's Nexi robot has been teaching us about social interaction for years, and has even done a stint with the US Navy. Its latest role, however, involved

studying those moments when society falls apart. Northeastern University researchers made Nexi the key ingredient of an experiment where subjects were asked to play a Prisoner's Dilemma-style game immediately after a conversation, whether it was with a human or a machine. Nexi showed that humans are better judges of trustworthiness after they see the telltale body language of dishonesty -- crossed arms, leaning back and other cues -- even when those expressions come from a collection of metal and plastic. The study suggests not just that humans are tuned to watch for subtle hints of sketchy behavior, but that future humanoid robots could foster trust by using the right gestures. We'll look forward to the friendlier machine assistants that result... and keep in mind the room for deception when the robots invariably plot to take over the world.

Top 10 Lies Of Science Your Teachers Told You In School

1. Law of Gravity was Discovered because of an Apple.
From Eve’s mistake to the proposition of law of gravity; apple enjoys exalted position among all other fruits. But the real stor

y of Isaac newton founding the law of gravity has nothing to do with the fruit.
In fact the story was tailored long after the discovery of law of gravity. Newton never mentioned the incident anywhere himself. So for now this tale is regarded as the biggest lie told to us in school.
 

 

 

 

 

2. Seasons are caused by varying distance of sun from the Earth
Here again, the reasons provided to us for having four seasons was the distance between earth and the sun. The part of

earth experiencing summer is supposed to be closer to sun, but it has been proved otherwise. Seasons are due to angle of earth on its own axis, it is due to this reason that many cities experience summer even when distance between sun and the earth is elongated.
Most radiations are received by the earth when it is perpendicular to sun, i.e. at an angle of 90 degrees on its axis. It is this angle which is responsible of variations in seasons

3. Black holes suck all the matter in environs
We have been told about the existence of a mysterious black hole in space which sucks in itself everything around it. But as the discoveries say, the hole does not necessarily suck in everything. The stars which collapsed in the black hole owe it to some exclusive processes. Its mass and gravitational pull is quite low to attract objects to itself. Rather, misconceptions are caused due to the stronger gravitational forces on its outer surface only

 

 

4. Great Wall of China is visible from the moon
The rumor basically spread by Richard Halliburton and endorsed by teachers and syllabus setter. Literature has many instances mentionin

g the great wall being the only man made thing visible from the moon. There is no evidence found in observations made by Apollo astronauts, nor any account by the astronauts orbiting the earth. There are somehow, some images taken from upper space showing some thing of the “city lights” sort. The rumor has now been busted by Jay Apt


 

 

5.There are only 5 senses
This is the most common myth taught to children since early ages that we have five senses. Which means our brain can interpret five types of signals i.e. si

ght, smell, touch, sound and taste. But this myth has been busted by the discovery that our brain can actually sense 9 to 20 different types of signals: surprising isn’t it??
Scientist have expanded the theory to include that our bodies have some other senses as well such as sense of equilibrium and speed, nociception to feel pain, proprioception to sense positioning, thermoception for sensing temperature etc. the list also includes hunger, itching sense of time, sense of stomach need, nature call and a lot more

6. Carbon dioxide (CO2) is an injurious pollutant
The environmental societies with the mission of saving our habitat, reducing greenhouse effects always proclaim the production and co

nsumption of carbon dioxide to be injurious. In the pollutants section of our science book, CO2 topped the list. But this isn’t true. In fact, the presence of carbon dioxide is inevitable for life. It is taken in by plants and without this one gas, our existence would be impossible. The main culprit is basically nitrogen which is a major component our atmosphere; 80% of air is composed of nitrogen. If the ratio was 100% we won’t be able to breath. Though the toxic materials of industrial waste mixed with CO2 are liable for pollution

7. Bats can’t see
I still remember my science teacher; inspiring our awes and oo’s when she revealed the apparent fact about bat’s blindness, but alas, it wasn’t really true. The trut

h is that most of the scientist initially believed that the bats did not have eyes, since the primary sense they used to locate objects was bio sonar. Bio sonar is the ability by which bats produced sounds which echo back to tell them about the hindrances in their way and how far they may be. But bats do have eyes and that too can sight objects the same way as others, but they aren’t used as a primary sense

8.Eight glasses of water necessary for healthy life
Teachers and parents both emphasize on the apparently “proper” intake of water which according to them is eight glasses and is qui

te necessary for life. But the truth is, to keep ourselves hydrated not only water but other liquids such as juices as well as fruits and vegetables play their part too. In fact it has been observed that people survived without in taking water for several months while using juices and other substitutes. So the next time your mommy compels you to drink water, show her the facts

9. Everyone is different
We have always been taught that each of is different and have distinctive behavioral patterns. But this isn’t true in its sense. Experiments have proven that we humans only differ in outlook, but if exposed to similar situations we will behave on similar patterns. The reactions and responses might be different for different age groups and professions but even then, they are groups after all. This myth is false and we only believed in it because we were taught so

10. Duck’s Quake does not Echo
When inquired about the inaudibility of ducks’ quack, I was told that unlike other sounds it does not echo and thus does not reach our ear drum for us to sense that. But science has now proven it otherwise. It’s not about the quake being special not to echo but our ears who cannot respond to the particular frequencies the sound has due to some external conditions. This fact was proved after performing series of experiments in which the duck was allowed to quack in a room specially designed to reflect sound waves. The echo was then heard which put to rest the myth about its uniqueness

HOW TO SURVIVE A HEART ATTACK WHEN ALONE.

Since many people are alone when they suffer a heart attack, without help, the person whose heart is beating improperly and who begins to feel faint, has only about 10 seconds left before losing consciousness.
However, these victims can help themselves by coughing repeatedly and very vigorously.

# A deep breath should be taken before each cough, and the cough must be deep and prolonged, as when producing sputum from deep inside the chest.
# A breath and a cough must be repeated about every two seconds without let-up until help arrives, or until the heart is felt to be beating normally again.
# Deep breaths get oxygen into the lungs and coughing movements squeeze the heart and keep the blood circulating.
# The squeezing pressure on the heart also helps it regain normal rhythm. In this way, heart attack victims can get to a hospital.
