This week I am going to talk about the TitanIIIE-centaur. Four of these rockets were used to launch the voyager 1,2 and Viking 1,2.These vehicles used rocket power to just get it into earth orbit and then they used RTG(Radiostope Thermoelectric Generator) to power the spacecraft and to make it function.The main engines of the rocket use liquid fuel and during the launch it used 2 other solid fuel boosters to give it enough thrust to lift off.The first stage liquid fuel rocket provides 2,340 kilonewtons of thrust and the two solid rocket boosters provide 11,698 kilonewtons of thrust for liftoff. This spacecraft has a mass of 632,970 kilograms. The Saturn V rocket is about 4 times heavier than this spacecraft so compared its pretty light. This rocket has helped make history.

Glossary:

Liquid fuel: Fuel that consists of liquid oxygen and liquid hydrogen or aerozine and nitrogen stored in different fuel tank and are ignited in the combustion chamber.

The Saturn 5 rocket is the rocket that has the heaviest launch vehicle payload ever. It’s a liquid fuel rocket that mean that it takes liquid hydrogen and liquid oxygen. The rocket is divided into 3 parts. The crew stays in the upper part, the command module and attached to this part is the service module. This part like all of the part come off at different times in the mission, the service module comes off at the end of the mission when the command module reenters earth’s atmosphere with its heat shield so it does not burn up! This rocket was designed by Wernher Von Braun. This was also the rocket that landed the first men on the Moon(Neil Armstrong,Buzz Aldrin). This presentation was brought to you by Souvik the science guy.

This is blog challenge #6. This is all about digital footprints. So what is digital footprints? They are prints you leave behind like when you post pictures or text on your Facebook account or when you email your friend about something funny, these texts/pictures/videos get filed. Now some people post different avatars that don’t at all look like them why do you think people do this? My opinion on why people do this is…because people think they can get away with doing something bad like saying something bad about your friend, teacher or parent and these people think that people won’t recognize there identity! Of course this isn’t something bad like some person might be trying to hide his personal information. So it isn’t something bad or good. I hope you learned something about digital footprints and bye for now.

GUESSING THAT THIS IS A ORGANIZED TREASURE HUNT, BECAUSE WHO WOULD PUT A SIGN THAT
SAYS “A SECRET HIDES IN THIS FOREST”, BECAUSE THEN YOU WOULD BE EXPOSING THE SECRET. I ALSO THINK THIS BECAUSE PEOPLE WHO ARE RUNNING THIS PROGRAM WANTS TO ATTRACT ATTENTION SO THAT PEOPLE WILL EVENTUALLY REALIZE THAT THERE IS MORE TO THIS FOREST THEN TREES AND OTHER ANIMALS. THIS IS TO MAKE PEOPLE REALIZE THAT THE FOREST IS THE ONLY MEANS OF CREATING OXYGEN AND CREATING A STEADY SUPPLY OF FOOD FOR MANKIND. TRUST ME, I BET THAT’S THE SECRET!

Hello and welcome to the King Souvik space channel. Today, we are going to talk about the project called the Tomato Sphere. This project is all about growing tomatoes in space!! That’s cool…right? This project is happening because scientists/astronauts want to know if or if not they can grow food in space. There are many reasons to grow plants in space. One is that the plants will take the carbon dioxide that the astronauts breath out and will convert it into oxygen for the astronauts to breath. Another reason is that they will provide food for the astronauts. I saved the best part for last.. The best part is that you can apply your school for this project and your school might be given some of the 600,000 seeds that have been in space!!! You get to touch something that has been is space. Isn’t that great? So apply for this program and be a scientist your self, because I know that I am doing it! Don’t believe me?Well then go to this link…http://www.tomatosphere.org/. Thanks for reading!!

Have you ever wondered how much electricity you are using every year? Well if you had plot it on a graph you would know, right? In our house the electricity usage is 8.3 kWh per day and say our houses usage is a example suppose this is how much electricity you use in your house. Imagine if all the people in your city used as much electricity as you, that would be a lot of electricity. Now imagine how much the whole country is using. Now again imagine how much the whole continent is using. THAT’S A LOT OF ELECTRICITY so now that you have imagined how much electricity your continent is using, think about how to lower this usage. YES, I GOT IT CELEBRATE EARTH HOUR!!!!!!!! It starts at 8:30 today and goes on until 9:30. This is to my classmates, if you celebrate Earth Hour I will not be scientific for 1 week. But you have to have prove on your blog. To prove it you have to post a picture or video of you and your family celebrating Earth Hour.

Today, Voyager 1 has left the solar system behind! This spacecraft was launched 35 years, 6 months and 15 days as of March 20. This was the first spacecraft to fly by the planets Jupiter and Saturn. Now this spacecraft is the first manmade object to leave the solar system behind. This spacecraft carries a golden record that carries sounds of the Earth and pictures of life forms on our planet Earth so if aliens intercept this spacecraft they get this information. It has traveled for 11 billion miles and is out of the heliosphere and is going into interstellar space (space between two stars). If you want to learn more about this mission go to this link…http://www.nasa.gov/mission_pages/voyager/voyager20120820.html. Stay tuned for more news on space missions!!!!!!

I recently read the book MAKING BOMBS FOR HITLER. Its a pretty sad book, mostly about a girl who is seperated from her younger sister, Larrissa. The book is set in the time period when World War II was started(1939-1945). While Lida (the girl) is captured by the Germans/Nazis, her sister is also captured while all the dangers await Lida at prison camp, torture and work. She has to prove herself useful or else….But because she is good at sewing she gets of easy, Lida gets to go to the laundry and she sews clothes damaged in war,but more danger awaits her. Her only hope that she will locate her sister fast and escape together if she is alive and well. This book is a sad story (this is not a book for people who like happy endings) but I can tell you its exciting in the end. But if you ever get to see this book and if are ok with sad endings I really recommend that you pick it up!!
