2025, China Siap Tempatkan Astronot di Bulan

2025, Chna Siap Tempatkan Astronot di Bulan


Beijing's ambition to put an astronaut on the moon in 2025 and began an investigation to explore Mars and Venus in the five years from now.

Director of the China Space Agency, Ye Peijian, said China could make the first manned aircraft landing on the moon within 15 years from now. They even claimed to be able to send probes to Mars in 2013 and Venus in 2015.

"China has full capacity to achieve the exploration of Mars in 2013," he added, as quoted by The Guardian, Tuesday (21/09/2010).

Indeed in the last seven years China's ambitions to become the third country to put one of its citizens in space. Astronaut Yang Liwei, became the first astronaut into orbit in 2008.
Confirmed later this week, China plans to build the first space station around the year 2020.

"Space program has been developing very fast but of course, China still lags far when compared with the United States and Russia because they have the most advanced technology," said Professor Fu Song, deputy dean of Tsinghua University School of Aerospace in Beijing.

"This is clearly a very difficult task but I think in terms of technology, China can do it. The United States is technically capable of doing it almost half a century ago," he added.

Added as well, the moon is a world that is foreign to humans and there are many things waiting to be explored. He said there might still waiting for the energy resources found.

Ilmuwan Bisa ‘Baca’ Rahasia Otak di Komputer

Ilmuwan Bisa ‘Baca’ Rahasia Otak di Komputer
The human brain is like a maze that is difficult to predict. However, scientists have managed to change the code, the brain signals into a computer that can read human minds.

In recent years, a series of interesting and surprising experiment has been done to dismantle the labyrinth of the human brain. Far exceeded the limits, we seem very open mind on something new and interesting to watch as part of the human body functions.

The scientists in Utah announced that they successfully transformed brain signals into code words that will be interpreted in the computer.

Using sensors embedded in the brains of volunteers, scientists managed to record the electrical signals produced by the brain when someone reads ten words, like 'yes', 'no', 'hungry' and so forth.

After a few moments, the team was able to distinguish the signals the brain that correlate with certain words. The implication is that, someday, this technique can be used on paralyzed patients and people who are isolated due to brain damage.

Most people suffer difficulty communicating with their loved ones due to brain systems disrupted. Utah experiment is a series of recent studies involving "electronic telepathy 'where brain signals has been read by a password that is defined through a computer device.

For example, several years ago, scientists using a brain-scanner to monitor brain activity when volunteers are shown pictures of everyday scenes. The scanner has been studying how the brain reacts to thousands of images and patterns generated when the volunteers saw a picture.

Basically, the way the brain works is part of the human mind. This is nothing more than a twitch separate sides, like a muscle and the human heartbeat. However, the implications of mind reading can be a matter of controversy, related to the practical side and legality.

This allows devices such as soldiers or pilots to control and create a policy concerning the aircraft or tanks, with the power of the mind. Therefore, this technology will offer tremendous advantages for each country by expanding it.

Boeing 787 Tawarkan Kemewahan

Boeing 787 Tawarkan Kemewahan
In addition was made in the biggest building in the world, the Boeing 787 aircraft was also the first commercial use of carbon composites. This revolutionary aircraft passengers certainly will not suffer adverse effects in long-distance flights.

Boeing 787 not only appeal concerning the structure or size of similar houses, but also what is contained therein. Initially, Boeing designed the plane as an ordinary aircraft, but Boeing factory in Everett adds some phase of construction in the wings, tail and other parts of the fuselage.

Boeing 787 aircraft named and given a price of around U.S. $ 150 million (Rp1, 3 trillion), up to U.S. $ 200 million (Rp1, 8 trillion). Boeing 787 Rolls-Royce engines built in England although it is still a choice. Approximately 25% of the aircraft was built in England.

Boeing 787 is also the first commercially built aircraft centered on the composition of carbon. Boeing 787 inaugural flight was made in December last year with a short trip from Everett to Boeing Field, south of the airport in Seattle.

Build a new aircraft is a big job, so that the whole program could cost stunning, U.S. $ 45 billion (Rp409, 5 trillion). Design 787 takes 800 thousand hours on supercomputers.

Carbon composite technology has been present for decades and regularly used in test flights and military interests. But this 787 is the first passenger plane that uses 70% of carbon.

Yarn fibers are arranged in a particular layer, and woven into different directions. This technique creates a very lightweight material and very strong, at least four times stronger than steel.

A plane, usually consisting of a rectangular panel which tied together with tens of thousands of nails. However, with this carbon composite, the entire aircraft body parts can be made in a section that basically burned a giant oven called an autoclave.

What is unique, systems, cables and electronic materials limy in one section. Besides saving money, this will result in assembly time per aircraft is only four days.

Part 50 aircraft coming from different places divided in 17 U.S. states and ten countries, including England. Outsourcing systems needed to create a unique fleet of aircraft to transport.

One revolution of the passenger plane Boeing is certainly not going to suffer adverse effects in long-distance flights. So far most of the aircraft cabin pressure while flying at an altitude of eight thousand feet above sea level.

On the other hand, the 787 will have pressure, but the conditions are like at an altitude of six thousand feet. This can improve the comfort and help reduce the effects of jet lag (excessive dizziness tired of air travel).

Not only that, most systems that rely on hydraulic elements have now been replaced with electronic equipment. The computer will detect the problem, so the land can be alert to any event automatically, even when the aircraft is in flight.

This will enable more rapid turnover between flights and ensure airlines can minimize delays. When flying through turbulence, the software reacts quickly to make adjustments on the control plane.

Bumi Terbentuk dari Ledakan Bintang

Bumi Terbentuk dari Ledakan Bintang
A meteorite that landed on Earth almost 150 years ago was found to contain microscopic pieces of the exploded star, when our solar system was born.

Chemical composition of the Orgueil meteorite that hit France in 1864 showed that a nearby star explodes as a supernova about 4.5 billion years ago, just as the planets from the sun formed.

This research could solve the mystery of why the level of the metal element, chromium, and varies from one planet to another meteorite.

Studies of meteorites known as embedded role in grain Chondrite, researchers led by University of Chicago's Nicolas Dauphas.

These findings are reported in detail on the issue of Astrophysical Journal September 10.

Previously, scientists believed that the chromium 54, which is an isotope of the element, along with other chemical elements evenly distributed throughout the cloud of gas and dust from our solar system that collapses.

"This is very mixed, but apparently some of the material got there and not entirely homogeneous, and that the results are quite interesting," Bradley said Meyer, a professor of astronomy and astrophysics at Clemson University who do not work on the study.

For four decades, scientists hypothesize supernova explosion occurred about 4.5 billion years ago that might trigger the birth of the sun.

"Apparently at least one big star to contribute material to the solar system before birth," Meyer said in a statement.

UFO di Pedesaan Kanada Bukan Meteor

UFO di Pedesaan Kanada Bukan Meteor
Mysterious objects in the skies of rural Manitoba, Canada successfully immortalized in a photograph. Specialists assess the UFO was not a meteor.

Chris Rutkowski, an astronomer and expert UFO sightings, said the pictures taken by Brad Korponay on Sunday night at the Steep Rock, Manitoba, marking the first report UFO sightings in the area for a long time, Winnipeg Free Press reported.

"This is definitely not a bolide (meteor), because it looked very old," said Rutkowski.

"It does not look like an airplane. If I had to guess, it looks like a lantern China. I've never seen anything like this before ... although how lantern China exist in the steep rock, I do not know."

China flying lanterns consist of paper with a candle like a small hot air balloon.

UFO experts say, the possibility of foreign body origin was from an alien "is nil."

Satelit NASA Dibakar di Atmosfir Bumi

Satelit NASA Dibakar di Atmosfir Bumi
NASA satellite that spent seven years studying polar regions, successfully ended its mission on Monday (30 / 8). The satellite falls to Earth and burned up in the atmosphere.

Some debris from the Ice, Cloud, and land Elevation Satellite (ICESat) fell into the Barents Sea north of Norway and Russia at around 5 am local time, according to the orbital debris program office at NASA's Johnson Space Center in Houston.

The institute is lowered ICESat orbit in July and formally interesting to prepare the satellite back into Earth.

Survival of this plane will be very useful for understanding the dynamics of ice sheets and sea ice, NASA officials said.

ICESat mission has been to promote science in measuring changes in ice mass of Greenland and Antarctica, sea ice thickness, and height of vegetation canopy height of clouds and aerosols.

"ICESat is very useful for science," said Jay Zwally, ICESat project scientist at NASA's Goddard Space Flight Center in Greenbelt.

"This satellite is providing detailed information on how the Earth's polar ice mass changes over global warming and for the determination of government policy."

ICESat data showed thinning of Arctic sea ice very quickly, and shows the level of Greenland ice loss that contributed to the high increase in the sea, Zwally said.

"Thanks to the ICESat we know that the Antarctic ice sheet is not reduced as much as mentioned the current study," says Zwally.

Using ICESat data, scientists can identification lake network under the Antarctic ice sheet.

"ICESat team has done an excellent job ensuring the aircraft is not a threat to other aircraft or potential sources of orbital debris in the future," said Nicholas Johnson, Cief Scientist orbital debris at NASA's Johnson Space Center in Houston.

Although the ICESat mission has ended, NASA's research related to the polar regions of Earth will continue, officials said the agency.

NASA began to develop the ICESat-2 is planned to be launched in 2015 by including the far more advanced instruments into it

Mars Sebesar Bulan Purnama Hanya Hoax

Mars Sebesar Bulan Purnama Hanya Hoax

Jakarta-News Mars will look at the full moon back in circulation via email. But the news hoax (hoax) and has done every year, since 2003.

"Red Planet will be spectacular."

"Earth to Mars will be very close between two planets in history."

"On August 28th ... Mars will look as large as the full moon."

"PEOPLE ARE NO LIVING WILL NOW SAW AGAIN."

Each year, e-mail like that kept recurring like a virus. This trick comes from events that occurred on August 28, 2003 when Mars closest to Earth in 60,000 years.

The incident makes people don `t want to look at the red planet. But with a distance of 55.7 million kilometers, Mars just looks a little bigger and brighter than usual. Hubble telescope also managed to immortalize it.

But Mars will never look at the full moon. Astronomer Neil deGrasse Tyson, director of the Hayden Planetarium in New York stated: "Mars and the Earth is closer to 2003 in the past 60,000 years. But it was not more meaningful by telling me to swim a hundred yards on the California coast and then declare to the world, I've never swam this close to China before. " "

This week, Mars looks faint and barely visible at night in the western sky after sunset

Kamera HD NASA Rekam Es di Mars

Kamera HD NASA Rekam Es di Mars

Images from the camera of NASA Mars Reconnaissance Orbiter HiRISE is showing ice on crater 20 feet (6.1 meters) in the surface of Mars, SPACE.com reported on Friday as quoted from UPI.

Researchers suspect, the crater in the northern part of Mars was formed no later than April 2004, said Nathan Bridges, HiRISE science team member at the University of Arizona. The crater appeared in photos taken on June 6 and July 7.

"It showed that we can find ice in the far south," said Bridges. "Along with our research, this will be useful in determining where the shallow ice on Mars," he said.

Closing this ice covers an area of approximately 20 square feet (6.1 square meters). "Maybe this crater has the same depth as we dug in the ground at Phoenix in 2008 and then," he said.

NASA's Phoenix Mars Lander landed on the Martian arctic in May 2008 and found evidence of ice below the surface. During the next Martian summer "HiRISE team will probably take additional images to examine the crater," said Bridges.

Badai Matahari 2012-2013 = 100 Bom

Badai Matahari 2012-2013 = 100 Bom

This week, several U.S. media also reported the NASA warning about the tsunami that causes the sun rays in the earth's spectacular early this month. The incident is considered as the beginning of a potentially large solar storm damaged power lines across the surface of the earth

Even so, NASA has denied that the effects of solar storms will appear soon. They say, "This could have happened 100 years or 100 days to come '. But Australian astronomers are betting that this incident will be faster than expected.

NASA itself has been watching the solar storm since 2006 and reported that the storm peaks can occur in the most horrific years in Hollywood movies, in 2012.

Similar storms actually happened in 1859 and 1921 that caused various disorders in the world. This natural occurrence has deleted a large-scale communications network.

On the other hand, hurricanes in 2012 is estimated to have a greater potential for damage. "Based on the general consensus of astronomers, the Sun cusp storms expected in 2012 and 2013 will be the most violent phenomena in the last 100 years," said astronomy professor at the same time columnist Dave Reneke.

Basically, no one knows with certainty the impact of solar storms peak in 2012-2013.

Dr Richard Fisher, director of the division Heliofisika at NASA, said that super storms will strike like 'shock of lightning', thus affecting a disaster for health care, emergency services and national security throughout the world.

NASA said that the latest report from the National Academy of Science states that the solar storm could cause losses of more than U.S. $ 2 billion (Rp18, 2 trillion) involving high-tech infrastructure damage. Overall recovery process will take about four to 10 years.

The staff at the Space Weather Prediction Center, Colo., which hosted this exercise say that reliance on satellite technology is the same danger of causing damage to the global earthquakes and storms.

Based on the book description Guilty of Apocalypse: The Case Against 2012 by Lawrence F. disaster experts Joseph, this disaster will not cause paralysis in the world immeasurably.

Not only that, there was a theory that says that the trip point of the sun into the sun will pass through a kind of belt that controls weather on Earth. This belt will carry through the solar magnetic field. Point the sun is going to explode and thus affects the Earth's weather conditions.

"This always happens in cycles with a period of 40 to 50 years," says solar physicist David Hathaway of the National Space Science and Technology Center, USA.

Hathaway said that when the sun belt is moving, most will be gathered so that the magnetic field affects the activity in the future. "The belt continues to move in 1986 and 1996," Hathaway said again.

Some experts believe that the peak of this storm will attract the attention of almost all parties. In fact, scientists estimate that this storm will destroy any GPS technology and the solar storm of energy expenditure equivalent to 100 million hydrogen bombs.

"We know that this will happen soon but we can not be sure how bad the impact of what happened," said Fisher. "These systems will not work. This is the impact of solar storms. "
