Space probe according to the detection of object is divided into lunar probe, probe and interplanetary spacecraft, small body such as a space probe to leave the speed of the earth must be large enough to overcome or get rid of the earth's gravity, realize the deep space flight. The probe orbits the heliocentric elliptical orbit (double-cut orbit) that is tangent to the earth's orbit and the planet's orbit, and may meet the target planet; Increase speed to change the orbit, flew to target the planet can shorten the time in order to ensure the detector fly the double track to the planetary orbits and tangent with the target when the target planets also run to it, must be chosen in the earth and the target planet at a particular moment of relative position detector. Detector can fly around the star, the use of planetary gravitational fields accelerate continuous multiple planets orbit the significant characteristic of space probe is, flying in space for long time, the ground cannot real-time remote control, so must have the ability of autonomous navigation; To fly outside the solar system, away from the sun, solar arrays, and nuclear energy systems; It is necessary to adopt special protective structure to withstand very severe space environment. Landing or walking on the surface of the moon or planet requires some special form of structure

The use of solar powered energy has a positive effect inside environment because benefiting from solar power will not contribute to global warming, acid rains or virtually any pollution. When transformed from solar radiations, solar panel technology could possibly be changed to thermal energy or electrical energy. This may also are employed in numerous applications like in agriculture and analysis. At present, solar power has found in two areas namely to the output of thermal energy which could get hot water and producing of electrical power by making use of the photovoltaic cell.
But any car repair centre would do? No! We should choose the best for our cars. There are few points that should be kept in mind while choosing car repair centre.The repair centre should be well known in car repair & maintenance. It is probably a good idea to carry out a thorough research on them and also ask for recommendations from the past clients. Past clients’ testimonies will choose better. They should have worked in this field for few years and have gained their customers’ trust. For them, customer delight should be their first objective and hence they are able to get repeat business. For this, they should have excellent relations with customers and they should have a helpline to connect with the customers. If the car has met with an accident, then the car repair centre should immediately send someone to check and repair the car.  They should have experienced specialists who carry out any kinds of repairs, be it – car dent, scratch repair, accident repairs or car bumper repairs. They should be qualified enough to carry out the repair work. The car repair specialists should be able to offer honest advice to the clients and work with a lot of care. They should be able to repair and return the car on the same day if the repairs are small. If there is a car dent, car repair specialists should be able to carry out the repairs without the intention of replacing the car panel. Even if there is an average size body repair then the repairs should be carried out in 2-3 days.The repair centre should be able to give an estimate without charging any fee. A lot of repair centres also offer free pickup and drop services. This is quite helpful for the customers who are elderly or are unable to come to pick their car. A lot of good repair centres are able to help the customers for pre-sales preparation. This helps in increasing the value of customers’ cars.Also, the car repair centre should not quote exorbitant prices for the maintenance and repair of the cars. In fact, a lot of reputed centres have a very competitive pricing. This way, the repair centre will be able to retain and increase their customers.
