Three days after arriving at the International Space Station (ISS), the Brazilian astronaut, Marcos César Pontes, has already initiated six of the eight experiments he will conduct before returning to Earth on April 9.

"The timetable is being adhered to with great precision," said Marta de Carvalho Humann, assistant coordinator of experiments on the Centennial Mission, the way Brazilians refer to Pontes' participation in the ISS.

It's been 100 years since Brazilian aviator Alberto Santos Dumont flied his 14-Bis in Paris, winning a prize for conducting the first self-sustained flight ever over 25 meters, which was observed.

One of the experiments, using bean plants, is intended to verify how plants produce chlorophyll in space. The study, which was proposed by primary school students in São José dos Campos, in the interior of São Paulo state, also wants to investigate how bean sprouts germinate in near-zero gravity environments, such as on the ISS. The latter part of the experiment is still underway and will only be completed when Pontes' mission there is over.

Another partially concluded experiment involves protein clouds. A spray is formed containing various luminescent substances, such as those found in fireflies, to determine whether they mix together better in space than on the Earth. The quality of the mixture is established by means of photographs.

Two of the five stages of this experiment, which was assembled by Aristides Pavani, a scientist at the Renato Archer Research Center in the Campinas (São Paulo state) region, have already been completed.

Another experiment that is already underway is testing heat minitubes. The purpose of this study is to try to build a kind of miniature air conditioner for satellites. Tuesday, April 4, Pontes also began another experiment that also addresses the possibility of constructing mini-refrigerators for satellites.

The mini-refrigerators are called capillary evaporators. The experiment was devised by Edson Bazzo, a scientist at the Federal University of Santa Catarina. The apparatus envisioned by Bazzo attempts to imitate the flow of sap inside trees, except that it uses water circulating inside minuscule aluminum cylinders. This experiment is expected to take three days.

Two experiments are scheduled to be performed by Pontes at the end of his stay aboard the ISS. One of them will analyze how bacteria react to the intense radiation bombardment that exists in space. The author of this experiment is Heitor Evangelista da Silva, a scientist at the State University of Rio de Janeiro.

The other experiment that Pontes will perform during his last two days on the station is a test proposed by Alessandro La Neve, a scientist at the Industrial Engineering Faculty (FEI) University Center in São Paulo. La Neve wants to find out whether weightlessness affects the reactions of certain enzymes, which are substances found in living creatures.

My gosh, you are sooooo clueless!
Of course we have central air in Brazil....not in the poor regions, Brazil is very diverse.
Read more, travel more too....

Brazzil Magazine - Since 1989 trying to understand Brazil
  • Poor Women from Northeast Brazil Learn Joy of Meeting and Helping Each Other


    Joined hands The small, coastal town of Condé is located just a twenty minute's drive from João Pessoa, the capital of Paraíba. The Northeast of Brazil has historically been a place of encounter and mixing between peoples. For millenia groups of indigenous people fished, farmed, migrated and sometimes fought along this large, fertile area.

  • Ahmadinejad's Visit: Iran, Honduras and Brazil's Hypocrisy in Dealing With Them


    Ahmadinejad and Lula The Brazilian diplo-MÁ-cia (bad diplomacy) carries on its accelerated course towards the non-acknowledgment of human rights, although sometimes it takes pleasure in saying that it does precisely the opposite. The visit of Iran's president, Mahmoud Ahmadinejad, is another example of a diplomatic omission that verges on hypocrisy.

  • Lula Is About to Fulfill His Wish of Getting His Good Friend Chavez in Mercosur


    Lula and Chavez On July 4, 2006, representatives of Argentina, Brazil, Paraguay and Uruguay met in Caracas to sign the protocol for the entrance of Venezuela into the Southern Common Market (Mercosur). After two and a half years, the protocol was approved by the legislative bodies of Argentina and Uruguay, and as of now it may be only days away from being ratified by the continent's economic megalith, Brazil.

  • Denying Education is the Other AIDS. And Brazil Is Guilty of Inflicting It


    Children from a Diadema band Some sectors of the fight against AIDS have suggested that Thabo Mbeki, the former president of South Africa, committed genocide through his absence from the fight against the illness in his country throughout his two terms.

  • Child Labor Went Down in Brazil, But 5 Million Underage Workers Are Still Way Too Many


    Child labor in Brazil One hundred and eleven years after Brazil abolished slavery, the number of workers deprived of their freedom is still huge. They raise cattle, produce charcoal, sugar cane or timber. Some of them, most undocumented Bolivians, work in basements of small apparel factories in São Paulo and other metropolis.

  • Some Humility Would Do Lula Good. On Human Rights Brazil Has Long Way to Go


    A prison in Rio de Janeiro, Brazil On November 7, 2009 a few friends and I had an opportunity to take a look inside a Brazilian jail outside the city of Rio de Janeiro. We were able to take some amateur footage of our experience on video (see link below). It's no surprise, of course, that the typical Brazilian jail lacks some of the functionality of those in North America or Europe, but our experience that day was quite shocking.

  • Brazil's Amazon Rainforest Policy Is a One-Way Road to Disaster


    Trasamazonian road in BrazilDepletion of the Amazon Rainforest is not a new concern facing environmentalists, biologists, ecologists, and a growing number of the Amazonian indigenous peoples. For decades they have feared for the fate of the world's most biologically diverse and species-rich hothouse.

  • Geisy, Brazil's Miniskirt Student, Should Try US College Next Year


    Geisy Arruda from BrazilGeisy Arruda made history this week in Brazil, but for all the wrong reasons. What began as a poorly planned fashion statement has become a worldwide tale. Geisy decided to wear a pink mini-dress to her private college in São Paulo state, and after that, all hell broke loose.

  • Vigilante Groups in Brazil Trump Drug Gangs and Become Rio's New Authority


    Brazilian favela in Rio The push of vigilante groups in Rio de Janeiro's favelas (shantytowns) in the last three years is the most important and alarming information of the just-released study by the Rio de Janeiro University's Violence Research Center (Nupev-Uerj).

  • Brazil Police Use Press Coverage as Green Light to Kill and Invade Houses in Rio


    Rio police in a favela A dispute over drug trafficking territory in Rio de Janeiro has intensified lately, leaving in its wake unprecedented acts of violence, such as the downing of a police helicopter in the northern zone of the city on October 17.  Three policemen died and another two were injured.  This event has drawn the attention of the international media, who are raising the issue of public security for the 2016 Olympics to be held in Rio.
