NASA launches the Kepler telescope looking for planets similar to Earth

The U.S. space agency NASA launched from Cape Canaveral on Friday Kepler telescope mounted on a Delta II rocket, on a three-year mission to find planets similar to land in areas near the Milky Way.

.
The rocket blasted off from Cape Canaveral, Florida (southern U.S.) at 22H49 (03h49 GMT on Saturday), according to a report from NASA and 62 minutes later entered into orbit successfully.

.
The separation of the third stage of the Delta II rocket as it was planned to 721.53 km in altitude.

.
Kepler will observe the same point in space for three and a half, or about 100,000 stars in the constellations Cygnus and Lyra in the Milky Way.

.
At a cost of nearly $ 600 million, will be the star of the first NASA mission to find Earth-like planets orbiting at distances similar soles able to hold water and therefore high chances of there life.

.
"This mission seeks to answer a question that is as old as time - are there other planets like ours out there?" Said Ed Weiler, associate administrator of the board of NASA missions.

.

"It is not only a scientific mission is a historic mission."

.
The telescope will look in particular relatively small planets, which are neither so hot nor so cold that are rocky and have liquid water, which are conditions for life to exist eseciales said William Borucki, principal investigator for the Kepler project research center NASA Ames, in California (West).

.
"Kepler is a key element in NASA's efforts to discover planets that can be found similar to Earth's atmosphere," he said last month at a press conference Jon Morse, director of the Astrophysics Division of the agency space.

.
Equipped with the largest camera ever launched into space-a set of equipment of 95-megapixel CCD-known as the Kepler telescope can detect faint glow stars, barely perceptible, seen with the passage of the planets.

.
The device weighs 1.03 tons and has a primary mirror 1.4 meters in diameter and opening of 0.95 meters.

.
"If Kepler looked a little town on Earth at night from space, could detect a porch lights if someone passes in front," said project manager James Fanson.

.
astrophysicist Alan Boss believes that Kepler or the French satellite COROT, which has been in orbit since 2006, can find planets the size of Earth in the coming years.

. COROT
and discovered the smallest alien planet yet. With a little more than twice the diameter of Earth, the planet is very close to its star and is very hot, astronomers reported this month.

.
The astronomer Debra Fischer of San Francisco State University, said the NASA mission is a cornerstone in understanding what types of planets formed around other stars.

.

The information as required by Kepler said, "will help us to the day when we can see a pale blue dot as our planet, orbiting another star in our galaxy."

tickets already sold here for $ 200,000 space

There are 10 recorded
Argentine plan.

With a little imagination, in about three years could receive an Argentine tumbling in space.

.

Maybe it does, according to local custom, with the team jersey or your favorite football club on.

.
not yet know the name of fellow who will be the first to cross the threshold of the atmosphere, but we do know that Sergio Durante, Byblos Travel, will sell the ticket.

.

travel agent, 68, was selected in the country to market the services of Virgin Galactic, which now performs the world premiere of the base Spaceport America, located in New Mexico, USA From there depart to space the mother ships WhiteKnight 2, with the ferry SpaceShip 2.

.
Flights for the public begin to take place in the third quarter of next year, on a weekly basis and cost $ 200,000 per person.

.

Although the value seems too high, there are 250 prospective passengers from around the world noted, and in Argentina, according to the travel agent, there are about 20 people in a position to do so.

. Already

ten consulted, but can not reveal during their names.

.

"It is estimated that by the third year of the first trip rate will drop to about $ 50,000, that is a landmark in the history of travel ...

.

is unthinkable to the average human level, but there are people who care for the mere fact that he traveled into space.

.

addition, at some point, a TV cost $ 5000 or more, and now in every home, "said Durante, elated, to the nation.

.
By way of comparison, said a high-end travel Europe, for four people, can easily cost $ 60,000, which believes that space as a destination - lo and behold! - end becoming a boom.

.

"Like, I think that will not happen before the first flight departure and return smoothly, "he said, against any obvious question in this regard.

.
How has the trip? Well, after paying the fare, the tourist astronaut base should be moved to Spaceport America, which really works as a luxury hotel, to receive a three-day training.

.

Tourists can go with his family, which is included in the fare, and once surpassed that stage would be conditions aboard.

.
The total duration of the voyage, since the passenger boards the SpaceShip and return to Earth, takes about three hours, four minutes of which (yes, read well: "Four Minutes") is living the experience of a "world without gravity" outside the orbit of the Earth.

. The tourists

astronauts are allowed, at that point of the journey, give up their seats to fulfill the dream of floating and observed through panoramic windows, the curvature of the Earth.

.

The ship has a capacity of six seats, plus the location of the pilots, and return to Earth on its own.

.
The entire ship, designed by Burt Rutan, creator of Voyager, an airplane with which in 1986 turned the world without refueling, is a work of unparalleled aeronautical engineering.

.

glider is like a triple, composed of carbon alloys, which goes beyond any imagination of science fiction.

.
The only option to make space tourism, so far, were the Russian Soyuz spacecraft at a price that was about $ 20 million.

.
The galactic journey begins well.

.

Once the WhiteKnight 2 amounts to 12 miles high, let go of the SpaceShip 2 so that it can deploy the wings and through self-propelled, can reach a speed of 4000 km per hour.

.

That little ship, which travels six tourists, reaching some 110 kilometers of the earth's crust to dive, finally, in the suborbital area.

.

The return to Earth takes about 45 minutes [in http://www.youtube.com/ is very convincing simulations].

. SpaceShip 2
The hostess has no food or bathroom. Tourists can not carry hand luggage, let alone cellular phones.

.

The only accessory allowed the camera.

.
"Among the queries I received, there were some comical. Someone asked me if we were going to the moon I never thought in 30 years of work, who would sell travel into space," During said.

.

And among the FAQ also appears the issue of documentation.

.

"They have to forget the history to be able to start training, because there are some physical requirements while traveling at 4000 km per hour," said travel agent.

.

Preparation includes a ride on a machine "extractor" that subjects the body to a gravity six times higher than normal.

.
Moreover, according to Durante, just need your passport and visa to enter the U.S.

.

"To enter the stratosphere is not need anything like that, "he added.

.
- When do you think you can embark on the first Argentine?

.
-Argentines love to travel. I think that in three years will make the first.

Nanomedicine. 14/25. Disease and poverty in the Global South

"bag of tricks of nanotechnology, with inventing new molecules and manipulating existing course could marvel at its potential to improve health care ... nanotechnology may enable better early warning systems in the diagnosis of cancer and heart disease, cures for progressive diseases like cystic fibrosis, techniques for making implants like artificial hips more effective, even artificial kidneys. " "Barnaby J. Feder, "Doctors Use Nanotechnology to Improve Health Care", New York Times, November 1, 2004

Although nano-enabled medicine may provide benefits, it moves very fast in the absence of public debate to address economic and social impacts of long range.

Executive Summary This report examines the applications medical drugs, devices and nanotechnology-enabled diagnostic tools. What impact will the Nanomedicine in the pharmaceutical industry? Respond "nano-enabled medicine to the health needs of marginalized communities, especially in the global South? What role play? Medical applications of nano-scale technologies have the potential provide powerful new tools to detect, diagnose and treat disease at the molecular level. Nanotechnology enthusiasts argue that Nanomedicine will revolutionize health care.

developments include, for example:

• Nano-sensors that circulate within the body to monitor glucose levels, cholesterol or hormones. • Nano-gold shells are white in cancer cells, and that once identified the tumor cells can be destroyed with a laser is not invasive. • Nano-particles "smart" looking for a specific location within the human body and then accurately deliver a scheduled dose of medication.

• Luminescent Quantum dots that track a particular protein within a living cell.

• Nano-particles of silver to kill germs resistant to antibiotics. • Frames dimensional nano-structured to grow new tissue and organs.

Medical applications of nanotechnology may sound like science fiction, but they are a handful of drug-and nano-enabled devices are already here, and there are many more to come soon through technology of the minuscule. By mid 2006, 130 drugs and delivery systems, more than 125 devices or diagnostic tests, all based on nanotechnology have entered into a development phase preclinical, clinical or commercial.

The market for nano-enabled medicine (including supply of medicines, therapy and diagnostics) will jump from just over a billion dollars in 2005 to nearly ten billion dollars by 2010. Governments, not corporations, are those who take the lead in research and development in nanomedicine.

In the near future, the technologies that are intended to be used in the body-enabled by nanotechnology, erased any distinction between "therapy" and "improvement" and may alter, quite literally, the definition of what it means to be human. The industry and analysts predict that nanotechnology will increase profit margins, expand the range of intellectual property and discourage competition. New medical technologies are irrelevant to the poor if not made available or are unaffordable. Scientific innovation is useless if marginalized people lack access to technologies or existing treatment.
The researchers, funded by public funds and companies innovative nano-biotechnology, have become major players. Big Pharma remains on the margins, but the analysis predicts that will soon enter the game. Although nano-enabled medicine may provide benefits, it moves very fast in the absence of public debate to address economic and social impacts of long range. Some nanoscale products that you intend to use in the human body can be therapeutic, but there are still many unanswered questions regarding the impact of nanotechnology on health and the environment. Products incorporating nano-engineered materials could accidentally enter the body through the environment or food chain.

developments in nanomedicine could result in even healthy people when new nanoscale materials released into the environment can make people sick. No one is sure how to distinguish between benign nano and dangerous products and the emerging field of nanotoxicology is tinged with uncertainty.


technologies converging at the nanoscale (including biotechnology, neurotechnology and information technology) will reach far beyond the tiny devices to deliver drugs or diagnostic reagents at the cellular level, typical for sick people . The convergence technology make it possible, theoretically, alter the structure, function and capabilities of the
bodies and human brains. In the near future, the technologies that are intended to be used in the body-enabled by nanotechnology, erased any distinction between "therapy" and "improvement" and could alter the definition of what it means to be human.

Some argue that nanotechnology will help extend the range of human life far beyond a century ("eliminating premature death") and allow us to transfer information directly a nuestros cerebros. En última instancia, la amplia aceptación de las ecnologías de mejoramiento del desempeño humano —suponiendo que funcionen según su diseño— crearán una brecha basada en las “habilidades”, entre quienes pueden pagarlas y quienes no pueden (o aquéllos que decidan resistirse a ellas).

Se proclama que las tecnologías nanoescalares son las herramientas tecnológicas que nos ayudarán a lograr los Objetivos de Desarrollo del Milenio: los objetivos de Naciones Unidas para promover el desarrollo humano e impulsar la sustentatibilidad social y económica en el Sur global.1 Sin embargo, las innovaciones de la medicina nanológica Northern emerge and are designed primarily for OECD markets.

New nanoscale technology interventions that we now offer our bodies

claim will be stronger, more skilled, more durable. The core interventions that lead to improvements in housing and health, access to clean water and education, for example, may ultimately lead to major improvements in human health-edge medical technologies. But it is not unique. Emphasize medical solutions diverts attention and resources were channeled to non-medical aspects such as health and welfare Community.

drugs and nanotechnology-enabled devices will play a role in ensuring and lavigencia extend monopoly patents covering medicinal compounds and older drugs are not as effective. The industry and analysts predict that nanotechnology will increase profit margins, expand the range of intellectual property and discourage competencia.2 is quite possible that the companies engaged in business "as usual" medical innovations of nanotechnology further concentrate the power of the pharmaceutical industry and are not relevant enough to meet the health needs and poverty of marginalized communities.

The development of nano-enabled medicine (and its potential to meet global health needs) should be considered in a political context and social context. The global health crisis arises not from the absence of a medical technology or a lack of innovation. Despite decades of stunning advances in the ability to save or extend lives through technology, a third of the world's population can not stably access to medicines esenciales.3 There are parts of Africa and Asia this figure rises to more half of the population. According to published reports in 1988 and 2004 by the World Health Organization (WHO), the number of people without access to essential medicines remained fixed during the period of 16 years between the report and report. New medical technologies are irrelevant to the poor if not made available or are unaffordable. Scientific innovation is useless if marginalized people lack access to technologies or existing treatments.

In the current political and social context, a significant investment in research and development of Nanomedicine may not be the right prescription to address human health needs, especially in the global South. History shows that new technologies do not solve the complex problems rooted in social inequities and poverty. Since the beginning of the century, life expectancy fell in 38 countries around the world. Even in North America and Europe, where mortality rates decreased in a stable manner throughout the twentieth century, studies show that these declines were largely independent of medical interventions and should be attributed more correctly, to improve in nutrition and hygiene. The nano-enabled drugs and zeal in promoting the refinement of performance technologies threaten to remove the essential health needs of scarce research funds and development of medicine.
