NASA TO USE CONVERTED BOMBERS TO CHASE TOTALITY

NASA TO USE CONVERTED BOMBERS TO CHASE TOTALITY

In a classic plowed sword movement, two WB-57 aircraft piloted by the air program in the air processed NASA salute the shadow of the moon as it rushes to the contiguous US states Monday, August 21 in a daring mission of the science.

“We are going to observe the total solar eclipse with two planes, each with visible infrared cameras that take high-definition video,” said researcher at the Southern Research Institute (SWRI) in the Amir Caspi project at Universe Today.

“This is going to be the observations of the highest quality to date (solar corona) of its kind, in search of a rapid dynamic movement in the solar corona.”

Total solar eclipses give researchers a unique opportunity to study the solar corona – the ghostly glow of the Sun’s outer atmosphere seen only during the whole.

NASA offers a battery experience during the eclipse, including plans to intercept the moon’s shadow using two planes near the largest screen point in Carbondale, Illinois. After leaving Ellington Field, near Houston, Texas, and operated by the NASA Johnson Space Flight Center, NASA is the only pending operator of the WB-57 aircraft.

Flying at an altitude of 50,000 feet, the aircraft will intercept the 70-mile-wide shadow of the Moon. The shadow will move at 1400 miles per hour – twice the speed of sound – compared to the WB-57’s maximum aircraft speed at 470 miles per hour.

The flight extends the length of the screen from the 2 minute and 40 second views of the plant, up to a total of about 8 minutes between the two aircraft.

Both tactical bombers convert WB-57 Canberra follows the eclipse with dynamite (Night Airbourne Motion Imagery for terrestrial environments), two mounted tandem cardan 8.7-inch images, one for visible light and infrared. These are located on the nose of the plane and shoot at 30 frames per second.

This system was originally designed for about a decade to expel the United States space shuttle during re-entry after the Columbia disaster in 2003 and occasionally provided spectacular images SpaceX Falcon 9 Step 1 return during re-entry.

The solar corona is as bright as the full moon, and the team plans to make a “map” of the solar crown precisely in an effort to understand how the crown interacts with the solar photosphere and the chromosphere. Of particular interest is to understand how the energy of the waves and “nanoflares” heat the solar corona.

“What we expect to learn is what makes the crown so hot (with temperatures approaching a million degrees Celsius in general and regions from 4 to 10 million degrees Celsius above the sunspot regions, much Hotter than the dazzling photosphere) and keeps it under structure, “says Caspi.” Why do not we see a spiral disaster? “

In NASA simulation, people tote hardy, allergy-inducing molds to Mars

In NASA simulation, people tote hardy, allergy-inducing molds to Mars

For many terrestrial terrains, our planet is filled with pollen, spores and toxins in the air overcrowding the schnozes and turn respiratory signs. Unfortunately, space rock jumping can not help, a new NASA study suggests.

In a 30-day simulation on another planet, NASA researchers found that the fungi were following the artificial astronauts and established their own colonies. Many of these small space explorers excel at surviving in extremely difficult conditions, such as saline soils and high altitude acids of the Indian Himalayas or radioactive remains of Chernobyl.

And several fungi that survived the world in simulation are associated with allergies and asthma inside, researchers report this week in the journal Microbiology.

“The statement” where humans go, the microbes in the car with them “is true for mushrooms,” said Kasthuri Venkateswaran, lead author on Ars. He works at the Planetary Biotechnology and Protection Group at NASA’s Propulsion Laboratory.

“At present, most of our studies have been conducted to determine the dynamic changes in bacteria, not fungi,” he says. “This is the first study that examined the mushroom changes in a confined environment for at least 30 days of human presence in isolation using molecular methods.”

The NASA simulation is the first step towards understanding what may be worlds fungi – mycobiomes – our future space colonies. But so far, they seem to argue mycobiomes monitoring in the future. In addition to causing respiratory problems and allergies, fungi can cause infections and accelerate deterioration of materials.

Microbial migrants

For the essay, Venkateswaran and his colleagues had three students spend 30 days in the March lunar / analog 12-meter inflatable habitat 10 meters by 2.5 meters or ILMAH. During the test, the ILMAH was a closed system with little outlet or inlet past the air and samples (through an airlock).

Four times in the past 30 days, habitat students cleaned and cleaned eight locations at ILMAH, on days 0, 13, 20 and 30. On the outside, researchers collected swabs and attempted to grow and sequence genetic material from Swabs of fungi. In the end, 117 fungal isolates were grown and sequences were obtained from 113 of them.

Through the time points, researchers found that the total amount of mushrooms collected decreased, but the diversity – the number of different types – has increased. Fungal levels may have increased before humans did not move and were then crushed or crushed by humans during the mushrooms.

Over time, species of the genera Epiccocum, Alternaria, Pleosporales, Davidiella and Cryptococcus increased. Epiccocum and Alternaria, part of the family Pleosporaceae, were also the most abundant.

These are common home molds that can colonize the human body and produce toxins, volatile organic compounds and enzymes that can cause respiratory irritation.

The researchers also found a small increase in members of the family Cladosporium davidiellaceae Aurobasidium and in the family of Dothioraceae, some of which can survive in extreme conditions, such as the Antarctic ice. These fungi can feel right at home on any new planet they are.

NASA reveals space weapon to stop asteroids but what happens if it fails?

NASA reveals space weapon to stop asteroids but what happens if it fails?

NASA unveiled a space weapon that could prevent an apocalyptic land of asteroids hitting hidden but if the plan fails, Armageddon could be more real than we think.
Even theoretical physicist Stephen Hawking says it is only a matter of time until Earth, as we know, can be destroyed by an asteroid.

“This is not science fiction. It is guaranteed by the laws of physics and probability,” Professor Hawking said in a speech at the Starmus science festival this year.
He affirmed that if the human race did not begin to leave the Earth to another planet, that ran the risk of “annihilated”.

“Reclining in space will completely change the future of mankind. One can also determine if we have a future,” said Professor Hawking.
Science Daily reports Professor Alan Fitzsimmons astrophysicist also warns if an asteroid hits the earth, could destroy an entire city.

“More than 1800 potentially dangerous objects have been discovered so far, but there are many more waiting to find,” he said.

“Astronomers find the asteroids close to Earth every day and most are harmless. However, it is still possible that the next Tunguska surprise us, and although we are much better at finding the larger asteroids, it does us no good if We are not willing to do something about it.

The last major asteroid to collide with Earth was in 1908. The asteroid or comet of Tunguska exploded in a zone of forest in Siberia, flattening 2,000 square kilometers.

According to the source book of the Tunguska event, it was the largest impact event on Earth, with the estimated comet size between 60 and 190 meters wide. It is believed that the explosion would hit more than 80 million trees and have registered a magnitude of 5.0 or higher on the Richter scale.

Research on the event by the Italian researcher Giuseppe Longo, physicist at the University of Bologna, found that the explosion was able to destroy a city.

This year’s research from the University of Southampton has revealed that there would be winds and tsunami killers if an apocalyptic asteroid hits the ground.

Researchers say the winds caused by the asteroid could be more damaging than the asteroid itself and could eliminate millions.

The university said winds and shockwaves account for 60 percent of deaths if an asteroid struck Earth.

The researchers examined seven different asteroid impacts of the end of the world, such as heat, pressure, shockwaves, debris, tsunamis, wind gusts, seismic quake and crater, and shockwaves and gusts of wind were the More deadly.

“Shock waves from a peak of atmospheric pressure and can rupture internal organs, while gusts of wind have enough energy to make the human body work and flatten the forests,” the research said.

The investigation examined a number of different scenarios if an asteroid hit Berlin and London. If an asteroid was 50 meters wide and a blast of air traveled 20 kilometers and hit the two cities, it kills 1.2 million people in Berlin and more than 2.8 million people in London.

Scientists Discover Solar Cell That May Be The Most Efficient In The World

Scientists Discover Solar Cell That May Be The Most Efficient In The World

WASHINGTON: Scientists have developed a new solar cell that converts direct sunlight into electricity at 44.5 percent efficiency and could become the most efficient solar cell in the world.

The prototype incorporates several cells stacked in a single device capable of capturing almost all of the energy in the solar spectrum, the researchers said.

The approach developed by researchers at George Washington University (GWU) in the US Is different solar panels that could be seen on the roofs or in the fields.

The new device uses photovoltaic concentrators (CPVs), which use lenses to focus sunlight on tiny microscale solar cells.

Because of their small size – less than a square millimeter – solar cells using more sophisticated materials can be developed in a cost-effective way, according to the researchers.

The stacked cell is almost like a sieve for sunlight, materials specialized in each energy layer of a specific set of absorption wavelengths.

When the light circulates in the battery, a little less than half of the available energy is converted into electricity.

In comparison, the most common solar cell makes today only a quarter of the energy available in electricity.

“Approximately 99 percent of the power contained in direct sunlight reaches the earth’s surface falls between wavelengths of 250 nanometers (nm) and 2500 nm, but conventional materials for multi-junction high efficiency solar cells It can not capture the entire spectral range, “said Matthew Lumb, lead author of the study published in the journal Advanced Materials Energy.

“Our new device is able to unlock the energy stored in them long-lasting photons, which are lost in conventional solar cells, and thus provides a path to the achievement of the final multiunion solar cell,” said M. Lumb.

Although scientists have been working towards the most efficient solar cells for years, this approach has two new aspects.

Firstly, it uses a family of materials based on gallium antimonide substrates (GaSb), which are normally found in applications of infrared lasers and photodetectors.

The new GaSb-based solar cells are assembled into a structure stacked with solar cells at high efficiency grown on conventional substrates that capture solar photons shorter wavelength.

In addition, the stacking procedure uses a technique known as transfer printing, which allows for a three-dimensional assembly of these small devices with a high degree of accuracy.

Although this particular solar cell is very expensive, researchers believe it is important to show the upper limit of what is possible in terms of efficiency.

Despite the current costs of the materials involved, the technique used to create the cells is very promising, according to the researchers….

Scientists in China teleport first object 300 miles into space!

Scientists in China teleport first object 300 miles into space!

New Delhi: Terrestrial and space experiments are carried out around the world. With the race to reach zenith ever stronger by the second, innovative strategies to achieve the same are deployed by space agencies around the world.

In the most recent development, Chinese researchers have successfully teleported a photon with Earth’s orbit.

The photon has traveled all the way from the Gobi desert to a satellite under the name ‘Micius’, in orbit 500km in total.
Researchers owe their success to quantum entanglement, a process in which two particles react as no physical connection exists between them.

According to the Deccan Chronicle, “Micius” is described as a high sensitivity image receiver that is equipped with the ability to detect single photon quantum states thrown from the ground.

The satellite was developed to allow scientists to test with quantum entanglement, cryptography and teleportation.

“Long-distance teletransport has been recognized as a key element in protocols such as quantum networks and distributed large-scale quantum computing,” said the Chinese team in the MIT Technology Review.

“Past experience teleportation between distant places is limited to a distance of about 100 km due to the loss of photons in optical fibers or free terrestrial channels,” said Deccan Chronicle.

Quantum teleportation could be exploited to produce a new form of communication network, in which information is encoded in quantum states entangled photons, rather than strings of 0s and 1s.

The huge safety advantage would be that it would be impossible for a listener to measure photon states without disturbing them and revealing their presence.

According to The Guardian, Ian Walmsley, professor of experimental physics Hooke at Oxford University, said the latest work was an impressive step to fulfill this aspiration.

“This indicates palpably that the field is not limited to the scientists sitting in their laboratories thinking about strange things. Quantum phenomena actually serve a purpose and can really bring important new technologies.”

The advantage of using a satellite is that it particles light through space for much of your trip. Last month, the Chinese team has shown to send interwoven photons from space to Earth.

The latest work done the opposite: they sent photons from the base of the mountain to the satellite as it passed directly overhead, he told The Guardian.

At present, many similar analog satellites are being developed by various teams, including the European Space Agency and Canadian scientists. However, the latest results suggest that China opens the field.

Moon Express Set to Launch Robotic Lunar Spacecraft by Year-End

Moon Express Set to Launch Robotic Lunar Spacecraft by Year-End

A private company plans to use a robotic spacecraft to launch a series of commercial missions to the moon, some 45 years after NASA’s latest lunar landing, authorities said Wednesday.

Luna Express is developing a low-cost fleet of robotic spacecraft that can be assembled as Legos to handle increasingly complex missions, said Bob Richards, founder and CEO.

The initial spacecraft, known as MX-1E, must be controlled before the end of the year in a rocket-powered electron lab actuator, launched in New Zealand. Luna expressed the hope that the effort would receive a $ 20 million prize in Google, but Richards said victory was not essential.

Luna Express has raised more than $ 45 million from private investors to build its first spacecraft and purchase launch services.

“The Google Lunar X award wins … the cake,” said Richards.

Google offers a first prize of 20 million for the first privately funded team to land a spacecraft on the moon (about Rs 128 million rupees.); Ask him to fly, drive or jump at least 1,640 feet (500 meters) and transmit images and video to Earth. The second prize of 5 million.

The occupants until December 31 to launch their spacecraft.

Google also provides additional money for other measures, such as 5-km navigation (5.1 miles), touching near an Apollo landing site or searching for evidence of water.

Richards introduced the spacecraft design in Washington on Wednesday.

In addition to competing for the X Prize, Luna Express will conduct scientific equipment and payloads for at least three paying customers, including Celestis, based in Houston, which offers space-commemorative remains ashes.

Richards said the company would pay the initial mission, customers would finance them.

The company plans to establish a permanent robot base at the south pole of the moon to explore water and other materials. In 2020, the Moon Express plans to return lunar samples to the Earth for research and commercial sale.

The MX Series spacecraft can also be extended to move to other places, such as the moons of Mars. The company expects to complete the first spacecraft in September.

Ex-NASA Scientist, Businessman Held In Hyderabad Drug Racket

Ex-NASA Scientist, Businessman Held In Hyderabad Drug Racket

Hyderabad: A former NASA aerospace engineer was detained today with a businessman by authorities over the consumption of Telangana for his alleged involvement in a high-end narcotics racket ran here last week.

With the two new arrests, the total number of people detained in the painting was 12.

Aerospace engineer, Dundu Anish, a United States citizen, would have been found in possession of 16 units of LSD, a high-quality drug, authorities said the district ban and Special Taxes.

Anish had studied at Doon School, Dehradun, they said, adding that he previously worked with the US space agency NASA.

The probe revealed that the 29-year-old engineer had, in the last month, entered the ‘Darkness’ website at least eight times and ordered various amounts of narcotic drugs and psychotropic substances or NDPS (such as cocaine, LSD, MDMA), officials have said.

In the information he gave, the Special Task Force of the department arrested Ritul Agrawal, a businessman in charge of steel. The 26-year-old student graduated in Business Administration with a major business school based in the city, they said.

“He (Angrawal) also found himself in possession of narcotics.” He and Anish would order the equipment online and pay with bitcoins / encryption currency. “The defendant said NDPS substances are delivered by mail Said officials.

With the arrest of Anish and Ritul, the number of people behind bars for their alleged participation in the racket arrested on July 2 has exceeded 12 years.

The racket is based on drug trafficking such as LSD (lysergic acid diethylamide) and MDMA (methylenedioxy-methanethylem).

Five of them are B Tech graduates who had good jobs in multinationals.

The department had previously seized 800 “squares” of LSD, which each cost. Rs 3000 and 35 grams of MDMA over Rs. 1.4 lakh.

LSD, which is sold as a pill or liquid, is known to be one of the most potent chemicals in mood changes, while MDMA, commonly called “Molly” or “ecstasy” is mainly used as recreational drugs Or partial.

Trillion-tonne iceberg breaks off Antarctica, poses huge risk to ships

Trillion-tonne iceberg breaks off Antarctica, poses huge risk to ships

A billion tonnes of iceberg – one of the largest ever recorded – has moved away from Antarctica after many months of anticipation and can now pose a serious danger to ships across the South Pole, scientists said on Wednesday.

The birth of the 5800 square kilometer iceberg outside the Larsen C ice shelf reduced by more than 12% in the region and the landscape of the Antarctic Peninsula has changed forever.

Icebergs in Antarctica soak up the sun all the time, but because this one is particularly large, you have to be careful your way across the ocean as it could endanger sea traffic.

The event took place sometime between July 10 and today, researchers said they monitored the growing gap in the West Antarctic ice shelf for years.

Iceberg, probably called A68, weighs more than a trillion tons. Its volume is twice as large as Lake Erie, one of the Great Lakes.

The final advance of the fault has been detected in NASA MODIS MODIS instrument data, images contained in thermal infrared at a resolution of one kilometer and confirmed by the VIIRS Suomi NASA instrument.

The development of the fault over the past year has been monitored with data from Sentinel-1 satellite of the European Space Agency – part of the European Copernican space component.

Sentinel-1 is a radar imaging system capable of acquiring images regardless of cloud cover and during the current winter polar darkness.

Tone billions of icebergs from Antarctica Glacier The image published by the European Space Agency ESA shows a photo taken by the mission Copernicus Sentinel-1-July 12, 2017, when a piece of ice more than twice the size of Luxembourg has been Broken the Larsen, C platform of ice in Antarctica, causing one of the largest recorded icebergs and changing the outline of the Antarctic Peninsula ever.

Although the remaining ice shelf will naturally continue to push, “researchers have already shown that the new configuration is potentially less stable than it was before the crack.

There is a risk that Larsen C may follow the example of his neighbor, Larsen B, who disintegrated in 2002, following a similar failure of labor induced in 1995.

“We expected this event for months and we were surprised to see how long it took to her as the fault crosses the last kilometers of ice,” said Professor Adrian Luckman of Swansea University in the UK-a.

“We will continue to monitor both the impact of this birth event on the Larsen C ice shelf and the fate of this huge iceberg,” said Luckman, principal investigator of the MIDAS project that oversees the crack.

The iceberg is one of the largest recorded and future developments are difficult to predict.

It can remain in one piece, but is more likely to break into fragments. Some of the ice can remain in the region for decades, while parts of the iceberg can move northward into warmer waters.
