Trip to Mars    

Did you ever think that there is a trip to Mars that takes 30 minutes?? (14)

Because a trip to Mars today takes six to eight months to realize, the technique that could reduce that space journey is called directed energy propulsion. It consists of a high power laser shot between 50 and 100 gigawatts.(39)

NASA to send helicopter to Mars in 2020

First Space Helicopter

His name is "Mars helicopter," and the small, stand-alone drone will be sent to Mars in just two years, taking advantage of the Mars 2020 mission ride.

The small helicopter is considered a high-risk mission, for its novelty. After all, having a helicopter get support in an atmosphere as rarefied as that of Mars is not a trivial challenge. What counts in favor is that the gravity of Mars is about 40% smaller than that of Earth.
The development of the Mars helicopter began in 2013, when NASA realized that the view of robots, comparable to that of a standing human, limits the choice of interesting targets to be studied. A low-flying helicopter can get a detailed, high-resolution map of the region, helping to chart routes better.

The vehicle weighs just 1.8 kilograms, is 60 centimeters high, and its double counter-rotating wings of 1.1 meters in circumference will try to take advantage of the fine Martian atmosphere spinning at almost 3,000 rpm - about 10 times the wings' rotation of a helicopter on Earth.

Solar cells are expected to recharge the lithium-ion batteries that feed the motors of the small drone, which also has a heating system to keep its instruments at operating temperature - the average temperature on Mars is around -60 ° C.

The helicopter will go to Mars hanging on the bottom of the Mars 2020 robot, which will leave it in a safe place and then pull away so that the vehicle can be put into operation and show its worth.

In its first flight, the helicopter will make a brief vertical ascent until 3 meters of altitude, where it will be for about 30 seconds. The initial testing campaign, scheduled to last 30 days, will include five flights at increasing distances, up to a few hundred meters, and durations of up to 90 seconds.

"We do not have a pilot and the Earth will be several light-minutes away, so there is no way to control this mission in real time. Instead, we have an autonomous capability that will be able to receive and interpret commands and then fly by own account, "Aung said.

Scientist turned mother

                                                           Mothers Day

The São Paulo-born Ligia Moreiras Sena, founder of the site "Scientist Who Became Mother", wanted to be an aeronautical engineer. At the age of 15, his professional aspirations included a degree in ITA, Institute Technological of Aeronautics . But at the time, the institute did not accept women.

"This was the first impact that I, as a girl, found on being a scientist," said the biologist, now a PhD in Sciences and Collective Health from the Federal University of Santa Catarina (UFSC). "Although I did not identify this as I understand it today, ie as a consequence of structural chauvinism and the patriarchy of society, it was already a major impact for me at that time."

With the desire to be a scientist since adolescence, she changed her plans and graduated in Biology from Paulista State University (Unesp). His work in the biological sciences began with research on neuroscience and neuropharmacology, an area where he devoted his productions both to the master's degree in science by the University of São Paulo (USP) and his first doctorate, also in science, by UFSC. But everything changed when Sena became pregnant with Clara, now seven years old.

                                                           My holiday
Hi everyone, I did a lot of things on my holiday and one of them I went by car  to a shop in the silva bueno street and bought it a rubber. I went to the cashier and the girl passed my eraser through the bar code reader (also known as a scanner that emits a red light that traverses the bars making their recognition through the color or the absence of it, then the optical reader of the code bars captures the product information in a few seconds and passes the information to the computer). After that I went to my house for dinner and sleep.
