Everyone has done experiments in high school laboratories,but have you ever thought about designing a satellite to explore space?

On Nov.19,a team of students from Thomas Jefferson High School for Science and Technology in the US awed peers and even scientists by successfully launching a satellite.

The first satellite designed and built by high school students was sent up into space along with a record-setting.28 other small ones on a rocket were sent from a NASA center in Virginia,CNN reported.It took the students seven years to build.

The students call their tiny satellite TJ3Sat,which is named after their school.It is just 10x10x12 centimeters and weighs only 0.89 kilograms,according to Orbital Sciences,a company which developed the rocket and supported the students’ project.It can be controlled with a smartphone.

Like most satellites,TJ3Sat can send and receive data.The small spacecraft is equipped with a voice synthesizer (合成器),which can switch text to voice and transmit those sounds back to Earth over radio waves,said Orbital officials.In this case,anyone can give it a try via the project’s website (school website) by submitting (提交) a text.The texts that get approved will be sent to the satellite,changed to voice and then broadcast back to Earth via radio waves.

“I can say ‘Go Colonials’on our ground station and when it is on the other side of the world,in India,someone can hear‘Go Colonials’over the radio,”the team explains on the website.

The satellite will stay in space for at least three months.

School principal Evan Glazer told The Washington Post that the project started in 2006 as an activity in the spare time.Later it became a research project for a select group of seniors.

At a time when American students are busy with SATs,the launch of the satellite shows what diligent teenagers can achieve when allowed to pursue their own curiosities,Glazer said.

“It used to be that kids growing up wanted to be an astronaut,” Andrew Petro,program executive (主管) for small spacecraft technology at NASA,said in a statement.“I think we might be seeing kids saying what they want to do is build a spacecraft.The idea here is that they really can do that.”

The single most important factor that contributes to success is what you do every single day.It is as simple as that.Your habits will determine whether you are successful or not.If you have strong and healthy positive habits,it does not matter whether or not you fail today because you are guaranteed to succeed in the long run.

1._______________________________

Because you repeat the same actions and the same behaviors every single day,a single positive action will not change your life,but the same action repeated 1,000 times will have a significant impact on your life.For example,if you go to the gym one time,you won’t see a big difference in your life.However,if you go to the gym 1,000 times over a five year period,you will see a big difference in your body.The same principle applies to finance,health,relationships,work,career,and school.Simple positive actions repeated every single day will have a great impact on your life in the long run.

2.________________________________

There’s nothing easier than developing positive habits.You simply have to do every single day the action you want to make a habit.If you want to develop the habit of running,run almost every day.If you want to develop the habit of eating healthy,eat healthy every day.If you want to develop the habit of reading,read every day.Habits are created by repetition.The more you do an action,the easier it becomes in the long run.

3.__________________________________

If you want to be successful in changing your habits,you should think about changing your inner beliefs about your habits.For example,your old belief was: “I love cigarette because it makes me feel good and relaxed.I need cigarette to be happy and relaxed.”If you keep this belief,you won’t be able to keep your resolution to stop smoking for very long.Instead,you should adopt this new belief: “I love yoga because it makes me feel good and relaxed.Cigarette is poisonous and destroys my body.Yoga makes me happy.” You should analyze your beliefs and make sure they won’t stop you from changing your habits.The same is true when you try to form positive habits.If you want to start eating healthy food,here are some positive beliefs you should start thinking about: “Healthy food is very good for my health.It gives me a lot of energy and I feel very good.”

4.____________________________________

It’s now time for you to develop positive habits in your life and avoid your negative habits.Write down 3 positive habits that you would like to develop and 3 negative habits that you would like to get rid of.For each positive habit,write down exactly what actions you’re going to take every single day in order to develop the new habit.For each negative habit,write down exactly what actions you’re not going to take in the next weeks.Here are some positive habits that will lead to success: exercise,healthy food,reading,saving,studying,healthy relationships,hard work,etc.Here are some negative habits to get rid of: gambling,drug and alcohol abuse,overeating,shyness,etc.

5._____________________________________

Everybody can change.All it takes is courage and commitment.Decide right now to improve your life by changing your habits.Take action right now!Don’t be afraid.Yes,you will probably make mistakes along the way.But never forget that success is guaranteed for you if you have positive habits in your life.If you refuse to quit,success will be yours.

As he took the top spot on Forbes(福布斯)28th Annual Billionaires list last year for the fourth time,he said he is pretty basic when it comes to so ending on clothes and food,but that he enjoys investing in shoes and racquets(球拍)when he plays tennis.

When asked a life lesson he had to learn the hard way,the billionaire said staying up too late is a habit he is still trying to break.‘‘Don’t stay up too late even if the book is really exciting.You will regret it in the morning.Pam still working on this problem,”he said.
