Will you distinguish between missions that were planned as "landers" and "crashers"?

(Voice over a loud speaker) Attention all participants. Today we will be steering our spacecrafts onto other planets. Each participant has submitted a spacecraft that will be used in their mission today to a foreign object. You can choose from several things to visit. This list includes:Earth's moon, Venus, Mars, Asteroid Eros, Jupiter, Saturn's Moon (Titan), Comet 9P/Tempel 1, and Asteroid Itokawa. You may choose where you want to land but if your spacecraft is damaged, your money and equipment will not be refunded. This activity is not recommended for those faint of heart, "un-nerdy", not a lot of free time, and especially those that get easily bored with Physics. Please remain seated at all times unless your craft has landed or on a continuous cruise. We hope you enjoy the program we have for you this evening. Thank you and keep it nerdy.

(USA Apollo program) "Alright crew, we have come to the decision that our best place and possibility of landing in the shortest amount of time is the moon. It will only take us three days to get there, so we wont have to watch the same movie too many times. We could have when to Mars, where I suspect we would have made a significant finding, but I am not sure how long we will be able to keep in contact with the Rover and I dont thing we have the time for such a tedious misson. If only we could find a way to travel faster than the speed of light, then we wouldn't have to waste so much time floating around the universe. I wonder how the Russians are doing?"

(USSR Vega Program, translated from Russian) "Today we are going to visit Venus. I do not care how many times we have to launch spacecraft, I want to land there. Those silly Americans are thinking small, landing on the moon. We have the time, technology and money to get to Venus. I mean, what else are we supposed to do with our time? Govern our people...HAHAHAHA. Anyway, back to business. I know we will find something, one way or another."

(ESA Beagle Series) "Alright people, we are soing this because everyone else is so let's not look stupid. I know we don't really care about any of this but since we have the money, let's spend it. I like the name Beagle and Mars, they just go together. So let's send a beagle spacecraft to Mars, yeah sounds good. I don't care if we win this contest, I just don't want to lose. Let's see what kinda pretty pictures we get back."

(Japan Hayabusa, translated from Japanese) "Okay, I think we should go to Itokawa. I mean, what else are we going to do. Everyone knows we have the technology to be the best. Everyone is expecting us to turn in something great so ya know what, we will. When Hayabusa gets to Itokawa, we will be the best. I don't think anyone else is going for it anyway. Wahoooo Japan."

(Voice over loud speaker) Okay everyone, now that you have each chosen your missions, you may get started the rules are...the person to submit the best, most, and coolest information wins the contest. You may use any technology you possess to get to your site but the mission must be completed in a week good luck.

(After one week) Congratulations on all of your achievements on your missions. Thank you USA for discovering that the moon has polar ice caps and extensive research on craters. Also, than you USSR for learning that there are volcanos present and most of the atmosphere is made up carbon dioxide. Thirdly thank you ESA for your findings that Mars was once completely drenched with water. Finally, we have learned from Japan that Itokawa is not a typical asteroid and they provided a sample.

After conclusions and scoring by our judges. The winner of our contest is...the United States of America. They have sent spacecraft to almost all of the deignated areas and have the most collaborated information out of everyone. Thank you USA for all of your knowledge...and money.

Na0Na ~ Spacecraft ArticleEdit

By using different technologies, astronomers are able to build these spacecrafts to gain a better understanding of these bodies around us. However, some of these spacecrafts were not successful. The spacecrafts that were successful provided astronomers with valuable information and detailed pictures.

Each spacecraft had a destination and a duty to perform. According to documentation, spacecrafts have landed and sent information from the moon, jupiter, venus, camets, saturn's moon, asteroids, and mars. The data that was received from these machines ranged from pictures to an in-depth analysis of the substances that make up the planet.

Numerous spacecrafts have landed and flew by Earth’s Moon since the year of 1958. Many of these spacecrafts were launched from the United States, being followed by the USSR with the lunar series. The USA released Pioneer zero, one, three, and four to fly by and orbit the moon. However, it was the USSR who created the first spacecraft, Luna, which landed on the moon September twelfth of 1959. Overall, the USSR landed a spacecraft on the moon about fourteen times. The United States have four programs that are used for the purpose of the moon: Ranger, American Surveyors, Apollo, and Discovery Program. The first spacecraft landing was on January 26th of 1962 by the spacecraft Ranger.

After approximately 50 years later, Japan made its first landing on the moon with the Hiten Series. They were followed by ESA (European Space Agency) with the Smart series spacecraft. These spacecraft landings gave scientists valuable information regarding the moon. They discovered craters; ice on the north and south poles, and water vapors was not present.

Next, spacecrafts have landed or flew by the second planet from the sun Venus. Venus has acid rain and a pressure 92 times greater than the earth. Therefore, the spacecrafts that approaches Vens must be sturdy, which is shown with the USSR spacecraft, Venera. On June eight and fourteenth of 1975, Venera nine and ten landed on Venus. Another series called Vega, were spacecrafts mainly used to fly by Venus. On the other hand, the United States made one landing on Venus, in comparison to the USSR fourteen landings. The Pioneer Series transmitted signals for 67 minutes and one of the four atmospheric probes survived. Important Information about Venus was discovered from the spacecrafts. Venus’ atmosphere is made up of carbon dioxide, the surface is 875 degrees Fahrenheit, volcanoes were present, the water evaporated, and is now contained in the clouds causing acid rain.

The Viking, Sojourner, and Mars Programs are US programs used for spacecraft exploration of the fourth planet, Mars. The spacecraft Marines was the first launch of a Mars fly by spacecraft in February o f 1969. It was not until the time of 1973 when the United States released Viking in August as a Mars orbiter and a having a successful landing. The USSR also had a Mars program landing the first spacecraft in history on the planet Mars on May 19th in 1971. The total landings for the United States are six and three were made by the USSR. The information that was discovered about Mars was that at one point it was drenched with water, may have sustained life, and it’s year is 687 Earth Days.

The asteroid Eros was the next place of landing for the United States. February twelfth of 2001, the NEAR spacecraft made a controlled landing onto the asteroids surface. After a four year journey and one year of orbiting Eros, the spacecraft landed. The spacecraft used laser radar to measure the asteroid Eros. In conclusion, Eros is the second largest near earth asteroid.

Another spacecraft landing done only by the United States was to Jupiter. They were successful in sending six spacecrafts to Jupiter since 1973: the Pioneer Series, Voyager SEries, Galileo, and Ulysses. Some probes flew around Jupiter sending back images of the planet; specifically, the Great Red Spot. It was found that Jupiter's radiation by the belt affected the probes around the planet. The magnetic field of Jupiter is very large in comparison to other magnetic fields of our solar system. The atmosphere of Jupiter is thick and contains both hydrogen and helium.

The European Space Agency, or ESA, launched the Cassini-Huygens Probe to land on Saturn's largest moon, Titan. On January 14th of 2005, the probe landed successfully on Titan suppling scientists with pictures and information regarding the surface of Titan. The surface temperature is about -248 degrees Fahrenheit and that Titan has an atmosphere. Scientists consider Titan one of the most interesting bodies in our solar system. It is larger than both Pluto and Mercury, and believed to have methane lakes and other chemicals.

The spacecrafts that have visited other planets has opened more doors for the exploration of our solar system. These probes bought or transmitted valuable information concerning that planet that can be used to develop and support theories. They give scientists a better understanding of the components of a planet, moon, or asteroid.
