Este é um caderno didático sobre os satélites artificias e a sua importância para as pesquisas científicas. Por meio de estudos os quais foram introduzidos por diversos conhecimentos, principalmente, a física em geral, são apresentados a tecnologias que tornaram sinais de TV, de GPS e de rádios importantes para o dia a dia.
Temos a proposta de apresentar o que é de fato está máquina, suas características e uma curiosidade da diferença deste para um satélite natural, assim como a realização de um experimento que simula o movimento rotacional dos satélites artificiais no espaço.

Simplesmente Hubble
O telescópio havia sido concebido de modo que pudesse sofrer manutenção regular, mas depois que o problema com o espelho veio à tona, a primeira missão de manutenção assumiu uma importância muito maior, e os astronautas teriam que realizar um extenso trabalho no telescópio para instalar a óptica corretiva.

Os 60 Anos do Sputnik-1 - Space Today TV Ep.889
4 de Outubro, um dia histórico para quem gosta de qualquer coisa relacionada com o espaço, e na verdade deveria ser um dia comemorado por todos, pois toda a tecnologia que temos hoje no bolso teve sua origem no dia 4 de Outubro de 1957 (Space Today).

The Summer Solstice Has Arrived!
This year’s summer solstice for the northern hemisphere arrives at 11:54 a.m. EDT, meaning today is the longest day of the year! The number of daylight hours varies by latitude, so our headquarters in Washington, D.C. will see 14 hours, 53 minutes, and 51 seconds of daylight. A lot can happen in that time! Let’s find out more.
If you’re spending the day outside, you might be in the path of our Earth Science Satellite Fleet (ESSF)! The fleet, made up of over a dozen Earth observation satellites, will pass over the continental United States about 37 times during today’s daylight hours.
These missions collect data on atmospheric chemistry and composition, cloud cover, ocean levels, climate, ecosystem dynamics, precipitation, and glacial movement, among other things. They aim to do everything from predicting extreme weather to helping informing the public and decision makers with the environment through GPS and imaging. Today, their sensors will send back over 200 gigabytes (GB) of data back to the ground by sunset.
As the sun sets today, the International Space Station (ISS) will be completing its 10th orbit since sunrise. In that time, a little more than 1 terabyte-worth of data will be downlinked to Earth.
That number encompasses data from ground communications, payloads, experiments, and control and navigation signals for the station. Approximately 330 GB of that TB is video, including live broadcasts and downlinks with news outlets. But as recently-returned astronaut Serena Auñón-Chancellor likes to point out, there’s still room for fun. The astronauts aboard the ISS can request YouTube videos or movies for what she likes to call “family movie night.”
Astronauts aboard the station also send back images—LOTS of them. Last year, astronauts sent back an average of 66,912 images per month! During today’s long hours of daylight, we expect the crew to send back about 656 images. But with Expedition 59 astronauts David Saint-Jacques (CSA), Anne McClain (NASA), and Oleg Kononenko (RKA) hard at work preparing to return to Earth on Monday, that number might be a little less.
Say you’re feeling left out after seeing the family dinners and want to join the crew. Would you have enough daylight to travel to the ISS and back on the longest day of the year? Yes, but only if you’re speedy enough, and plan your launch just right. With the current fastest launch-to-docking time of about six hours, you could complete two-and-a-half flights to the ISS today between sunrise and sunset.
When returning from orbit, it’s a longer ordeal. After the Expedition 59 trio arrives on Earth Monday night, they’ll have to travel from Kazakhstan to Houston to begin their post-flight activities. Their journey should take about 18 hours and 30 minutes, just a few hours longer than the hours of daylight we’ll see today.
Happy solstice! Make sure to tune in with us on Monday night for live coverage of the return of Expedition 59. Until then, enjoy the longest day of the year!

It’s almost launch day! On Monday, June 24, the launch window opens for the Department of Defense’s Space Test Program-2 launch aboard a SpaceX Falcon Heavy. Among the two dozen satellites on board are four NASA payloads whose data will help us improve satellite design and performance.
Our experts will be live talking about the launch and NASA’s missions starting this weekend.
🛰 Tune in on Sunday, June 23, at 12 p.m. EDT (9 a.m. PDT) for a live show diving into the technology behind our projects.
🚀 Watch coverage of the launch starting at 11 p.m. EDT (8 p.m. PDT) on Monday, June 24
Join us at nasa.gov/live, and get updates on the launch at blogs.nasa.gov/spacex.

satellite emoji ratings
by yours truly
im rating these on… Satellite
a very nice boy! the gradients make it look a little earthly for a satellite, but it’s okay, because i love how reflective his solar panels are. 7.9/10 a good
google keeping it simple today with some blue colors, very sleek solar panels, with a dash of yellow. the curved edges make it look like a very chill young bro. 8/10 very cute
microsoft giving us a spunky boy with Very sharp edges. a design that’s vaguely reminiscent of a soyuz module, but not quite enough i can tell. 7/10 very good but a little pale.
i’m not sure how i feel about this one. on the one hand, i love all satellites, but this one has a cryptid feel to it. with its solar panels facing the same way as the antenna, isn’t it just proadcasting directly into the sun? i don’t know how i feel about that. also, facing towards the sun when it shouldn’t have is how the mars global surveyor died, so i have… negative feelings about this little buddy. 4/10 :/
simple, shiny, gets the idea across without too many clashy colors or ideas. sleek. i like it. 8.2/10
another simple sat, with a BIG thingy and SOLAR PANELS which are BLUE. stylized, but i like it. 7/10
WHY SO SIMPLIFIED? WHY SO STRIPEY?????????????? 0/10 NEEDS MORE LOVE
this one’s hard to see against the white background, but it’s got a very nice look and i love it. it’s got some dimension. it really pops. 17776/10 i love this child and i will hug it
