With Brazil in Turmoil, Rio Counts Down to Olympics
By REBECCAR. RUIZAPRIL27, 2016
RIO DE JANEIRO- Brazil's president is facing impeachment. The country's economy is in sharp decline. Bodies of water that will be used for Olympic competitions are polluted, and global public health officials are trying to tamp down the Zika virus epidemic.
With less than 100 days before the Olympic Games come to South Amarica for the first time, Rio de Janeiro faces more than the usual challenges that bedevil host cities, like delayed stadium construction and transportation concerns. (Rio has those, too.) The mood here, however, is hardly one of panic. Officials in charge of executing the Summer Games say they feel insulated from Brazil's turmoil at this late stage. The Olympics, after all, tend to exist in their own bubble, elaborately coordinated to ensure that the multibillion-dollar operation goes off smoothly. "The machine is in place, and it's relatively stable," Ricardo Leyser, Brazil's sports minister, said in an interview this week. "My biggest concern isn't any individual issue. lt's the small demands that all come at once."
Local organizers are beginning to lay colorful comforters patterned with the silhouettes of cartoon cyclists, fencers and swimmers - on the twin beds in the athletes' village. They are monitoring the growth of 14-month-old grass that will be transplanted to Maracanã, the storied soccer stadium that will also be used for the opening and closing ceremonies. They are pulling trash from Guanabara Bay, where the Games' sailing events will be held; mopping up standing water to minimize mosquito breeding; and ramping up a round-the-clock security operation - all while publicly expressing little worry about the unrest encircling them.
On Wednesday, with the handoff of the Olympic flame in Greece and the start of a journey that in little more than a week will bring it to Brazil, the official countdown to the Aug. 5 opening ceremony began.
ln Rio, the race to be ready is intensifying, with construction workers here still laboring on mass transit projects that were key promises seven years ago in the city's bid to host the Games. Costing several billion dollars, those projects include a new subway line and express bus lanes that connect the Olympic Park in Barra da Tijuca to the rest of the city, which is expected to swell with more than half a million visitors.
As the value ofthe Brazilian real has drastically declined overthe last year, some have expressed doubt that the transit projects will materialize beyond the sleek, modernist weather shelters that have been built at various stations. At a news conference Wednesday, the city's secretary of transportation said the new routes would be ready i n ti me but did not specify when. To the vast majority of people watching the Games on television, however, such infrastructure may not matter.
The permanent venues for competitions here are mostly complete - all but those for tennis and track cycling - and athletes from around the world have competed in dozens of test events in Rio in recent months. "lt's about the filling of the cake," Mr. Leyser said. "lt's not about the stadiums; it's about the scoreboards."
As ofthe latest counts, 62 percent ofthe 5.7 million tickets on the market had been sold - roughly half of the total tickets for the Olympics - and 24 percent of tickets available for the Paralympics had been sold. But compareci with past Olympics, the buyers of those tickets may be disproportionately international, saidAndrew Parsons, the presidentofthe Brazilian Paralympic Committee.
For some Brazilians, the country's political and economic crises have cast a shadow on the celebration. President Dilma Rousseff's ouster looks increasingly likely amid a sweeping graft scandal, and those in line to succeed her have their own controversies hanging overthem.
Questions of corruption have extended to Olympics planning, particularly after a businessman who worked on many Olympic projects in Rio was convicted of corruption and money laundering related to separata contracts. Mr. Leyser said that the questions centered on irregularities at the Deodoro event site and that no publicofficial had been accused ofwrongdoing. "lt's more an administrativa issue than a corruption scheme," he said. "lt's basically a question ofthe numbers." Mr. Leyser called the devaluation of Brazil's currency an opportunity because it increases the buying power of foreign money coming into Brazil forthe Games.
But not everyone sees the event as a boon to the country. Shirlei Alves, who lives in the Santa Marta favela of Rio, criticized the government for spending on the Olympics in the face of Brazil's problems.
"The world is just getting worse here," Ms. Alves said, noting that she was without medication and electricity. "The government is making a mistake. l'd like if they'd take a better look at the poor people and not help people who are already rich." Eduardo Paes, the mayor of Rio, said Wednesday that the city had a "comfortable financial situation" and had spent on stadium construction 1 percent ofwhat it spent on health education. "I know people are skeptical," Mr. Paes said, citing the "huge deliverables" for the Olympics. "Of course the situation here has been difficult. But there is a commitment of the Brazilian state to deliverthe Olympics."
Perhaps the most vexing issue for local organizers-the one that may stir anxiety among athletes and spectators - is the mosquito-borne Zika virus, which has been linked to birth defects and temporary paralysis. Zika is of greater concern outside Rio, in the far north part of Brazil, but the World Health Organization has declared the virus a global public health emergency and has advised pregnant women notto travei anywhere in Brazil.
"The Olympics is a pretty effective way of taking whatever disease is local and making it global," said Ashish K. Jha, director ofthe Global Health lnstitute at Harvard.
Some scientists have suggested that by the time the Olympics start in August - wintertime in Brazil, when mosquitoes are less numerous - the virus might be more prevalent in the southern United States.
"Zika's been spreading effectively on its own, but there's very good reason to think the Olympics will accelerate the spread," Dr. Jhasaid.
But the virus poses a unique problem because it isso far beyond the contrai of local organizing officials, and so many questions about it remain unanswered. Few athletes have publicly expressed concern, but it is unclear how many might withdraw as the Games draw closer.
"At this point you just keep going," David Wallechinsky, an Olympics historian, said. "You have to continue as if everything's going to be fine. These are real concerns - Zika, the water quality. But even if Dilma is forced out of office, it's not going to stop the Olympics."

LARGEST AIRCRAFT IN THE WORLD

We have lift-off. The world's largest aircraft has taken to the skies for the first time.The Airlander 10 spent nearly two hours in the air, having taken off from Cardington Airfield in Bedfordshire. During its flight, it reached 3,000 feet (914 meters) and performed a series of gentle turns all over a safe area.
The aircraft is massive – as long as a football pitch and as tall as six double decker buses and capable of flying for up to five days. It was first developed for the US government as a long-rangesurveillance aircraft but was scrapped following cutbacks.
Each one cost 25 million pounds and can carry heavier loads than jumbo jets while also producing less noise and emitting less pollution. The makers, Hybrid Air Vehicles, believe it‟s the future of aircraft, and that one day we'll be using them to get places.
But we're a while away yet. The Airlander
will need to clock up 200 hours‟ flying time before
beingdeemed airworthy by aviation bodies. If it passes though, we can hope we'll all get some
extra leg room.

Mount Roraima, a Mystified Hiking Experience
Hiking here is not hard and you can also get help from the indigenous population, as they organize tour guides in exchange for a small sum of money. If you are on your own however, try to reserve at least four days for this fantastic journey, as there are plenty of things to see and enjoy up there. Mount Roraima is said to have some of _____________________ hiking trails in the world.
You should not leave after 2 p.m. from the village as trekkers are no longer allowed after this hour. At the beginning of your climb, your baggages will be strictly checked and you can not take more than 15 kilos with you. So careful how you organize things. Being given that this is a national park , you are not permitted to take rocks or plants along the way.
The top of the mountain measures 2772m, it offers amazing landscapes and establishing a tent around here is possible. However, you should know the weather changes suddenly in this area so be prepared.

Individually, the two phenomena are not uncommon, but they do not align often. NASA Researchers Studying Advanced Nuclear Rocket Technologies
January 9, 2013
By using an innovative test facility at NASA’s Marshall Space Flight Center in Huntsville, Ala., researchers are able to use non-nuclear materials to simulate nuclear thermal rocket fuels - ones capable of propelling bold new exploration missions to the Red Planet and beyond. The Nuclear Cryogenic Propulsion Stage team is tackling a three-year project to demonstrate the viability of nuclear propulsion system technologies. A nuclear rocket engine uses a nuclear reactor to heat hydrogen to very high temperatures, which expands through a nozzle to generate thrust. Nuclear rocket engines generate higher thrust and are more than twice as efficient as conventional chemical rocket engines.
The team recently used Marshall’s Nuclear Thermal Rocket Element Environmental Simulator, or NTREES, to perform realistic, non-nuclear testing of various materials for nuclear thermal rocket fuel elements. In an actual reactor, the fuel elements would contain uranium, but no radioactive materials are used during the NTREES tests. Among the fuel options are a graphite composite and a “cermet” composite - a blend of ceramics and metals. Both materials were investigated in previous NASA and U.S. Department of Energy research efforts.
Nuclear-powered rocket concepts are not new; the United States conducted studies and significant ground testing from 1955 to 1973 to determine the viability of nuclear propulsion systems, but ceased testing when plans for a crewed Mars mission were deferred.
The NTREES facility is designed to test fuel elements and materials in hot flowing hydrogen, reaching pressures up to 1,000 pounds per square inch and temperatures of nearly 5,000 degrees Fahrenheit - conditions that simulate space-based nuclear propulsion systems to provide baseline data critical to the research team.
“This is vital testing, helping us reduce risks and costs associated with advanced propulsion technologies and ensuring excellent performance and results as we progress toward further system development and testing,” said Mike Houts, project manager for nuclear systems at Marshall.
A first-generation nuclear cryogenic propulsion system could propel human explorers to Mars more efficiently than conventional spacecraft, reducing crews’ exposure to harmful space radiation and other effects of long-term space missions. It could also transport heavy cargo and science payloads. Further development and use of a first-generation nuclear system could also provide the foundation for developing extremely advanced propulsion technologies and systems in the future - ones that could take human crews even farther into the solar system.
Building on previous, successful research and using the NTREES facility, NASA can safely and thoroughly test simulated nuclear fuel elements of various sizes, providing important test data to support the design of a future Nuclear Cryogenic Propulsion Stage. A nuclear cryogenic upper stage - its liquid- hydrogen propellant chilled to super-cold temperatures for launch - would be designed to be safe during all mission phases and would not be started until the spacecraft had reached a safe orbit and was ready to begin its journey to a distant destination. Prior to startup in a safe orbit, the nuclear system would be cold, with no fission products generated from nuclear operations, and with radiation below significant levels.
“The information we gain using this test facility will permit engineers to design rugged, efficient fuel elements and nuclear propulsion systems,” said NASA researcher Bill Emrich, who manages the NTREES facility at Marshall. “It’s our hope that it will enable us to develop a reliable, cost-effective nuclear rocket engine in the not-too-distant future."
The Nuclear Cryogenic Propulsion Stage project is part of the Advanced Exploration Systems program, which is managed by NASA’s Human Exploration and Operations Mission Directorate and includes participation by the U.S. Department of Energy. The program, which focuses on crew safety and mission operations in deep space, seeks to pioneer new approaches for rapidly developing prototype systems, demonstrating key capabilities and validating operational concepts for future vehicle development and human missions beyond Earth orbit.
Marshall researchers are partnering on the project with NASA’s Glenn Research Center in Cleveland, Ohio; NASA’s Johnson Space Center in Houston; Idaho National Laboratory in Idaho Falls; Los Alamos National Laboratory in Los Alamos, N.M.; and Oak Ridge National Laboratory in Oak Ridge, Tenn.
The Marshall Center leads development of the Space Launch System for NASA. The Science & Technology Office at Marshall strives to apply advanced concepts and capabilities to the research, development and management of a broad spectrum of NASA programs, projects and activities that fall at the very intersection of science and exploration, where every discovery and achievement furthers scientific knowledge and understanding, and supports the agency’s ambitious mission to expand humanity’s reach across the solar system. The NTREES test facility is just one of numerous cutting-edge space propulsion and science research facilities housed in the state-of- the-art Propulsion Research & Development Laboratory at Marshall, contributing to development of the Space Launch System and a variety of other NASA programs and missions.
