Ares 3 Landing Site: The Martian Revisited
This close-up from the Mars Reconnaissance Orbiter's HiRISE camera shows weathered craters and windblown deposits in southern Acidalia Planitia. A striking shade of blue in standard HiRISE image colors, to the human eye the area would probably look grey or a little reddish. But human eyes have not gazed across this terrain, unless you count the eyes of NASA astronauts in the scifi novel The Martian by Andy Weir. The novel chronicles the adventures of Mark Watney, an astronaut stranded at the fictional Mars mission Ares 3 landing site corresponding to the coordinates of this cropped HiRISE frame. For scale Watney's 6-meter-diameter habitat at the site would be about 1/10th the diameter of the large crater. Of course, the Ares 3 landing coordinates are only about 800 kilometers north of the (real life) Carl Sagan Memorial Station, the 1997 Pathfinder landing site.

7 passos para ter uma dieta balanceada e saudável
Nós sabemos da importância de termos uma dieta balanceada, rica em nutrientes que trazem mais saúde e energia para nossas vidas. A questão que nos resta é: "Como conseguir ter uma alimentação balanceada com a minha vida corrida desse jeito?"
Nós fizemos uma lista com 8 maneiras bem simples de pensar em uma refeição para que ela tenha tudo o que precisamos e seja saborosa!
Como ter uma dieta balanceada?
- Procure consumir grãos integrais, como arroz e massa. Eles são ricos em vitaminas e ainda dão uma sensação de saciedade por mais tempo. Você come menos e sente menos fome!
- Prato colorido! Cada cor das frutas e legumes traz um nutriente e um benefício para nossa saúde. Por exemplo, alimentos vermelhos são ricos em antioxidantes e os verde escuro possuem ferro e vitaminas essenciais. Quanto mais colorido, mais completo é o prato.
- Proteína não animal. De vez em quando troque a carne por uma proteína não animal, como o grão de bico ou a quinoa. Elas possuem menos gordura e são mais leves.
- Sim para a gordura saudável. Vivemos fugindo dela, mas nosso corpo precisa de gordura para funcionar direito, principalmente o nosso cérebro. O abacate, as sementes oleaginosas, o salmão e o azeite de oliva são ótimas opções.
- Água! Este líquido transparente que muitas vezes achamos sem graça ajuda a desintoxicar o organismo e é essencial para nossas funções fisiológicas. O ideal é beber cerca de 2 litros por dia.
- Evite alimentos processados, que são ricos em sódio, açúcar e produtos químicos. Na dúvida se comprar ou não, leia o rótulo e se a maioria das palavra for enorme e você não entender o que é, não leve!
- Reduza bebidas alcóolicas e refrigerantes, que são cheios de açúcar e só fazem mal. Ao invés, opte por chá gelado, suco ou a boa e velha água.
Com essas dicas para uma dieta balanceada você já consegue escolher melhor o que comer para almoçar, mesmo se for em um restaurante por quilo. Outro fator importante é não encher o prato. Faça pequenos lanches entre as refeições para não sentir tanta fome e conseguir comer menos no almoço. Frutas e nozes são opções fáceis de levar para qualquer lugar.

ageBorn In Slavery: Interviews with Freed Slaves
from the Federal Writers’ Project, 1936-1938. By this point, the American Civil War had been over for seventy years. Most of the former slaves interviewed barely remembered their time enslaved. The Federal Writers’ Project set out to record their memories before it was too. There are more than 2,300 first-person accounts of slavery and 500 black-and-white photographs of former slaves, available online here.

May 16th 1770: Wedding of Marie Antoinette and Louis XVI
On this day in 1770, the French noble Marie Antoinette married the heir to the French throne, Louis Capet, at Versailles. The former was the daughter of the Austrian archduchess and the Holy Roman Emperor, and the marriage was arranged to strengthen the relationship between former rivals Austria and France. Their lavish wedding was attended by 5,000 guests, with 200,000 watching the fireworks display which capped the festivities. Perhaps due to their young ages - Marie was fourteen and Louis was fifteen - the marriage was not consummated for seven years. In 1774, after four years of marriage, French King Louis XV died, and his son ascended to the throne as King Louis XVI, with Marie crowned as queen. The monarchs proved controversial figures, with Louis struggling to deal with the affairs of the crown, and Marie drawing criticism for her extravagant tastes (earning the nickname ‘Madame Déficit’) and devotion to Austrian interests. Both opposed monarchical reform, a stance which spelled their doom as the French Revolution began. In the midst of the unrest, Marie and Louis attempted to flee to Austria in 1791, but were apprehended and returned to Paris. The royal couple were imprisoned in 1792, and the monarchy was abolished in the same year. For his efforts to thwart the revolution, King Louis XVI was tried for treason and executed by guillotine in January 1793. In October of that year, Marie Antoinette was also convicted of treason and faced death at the guillotine. Their deaths were turning points in the French Revolution, and indeed in the history of France.
