I suggest that the space tourism leisure businessmen can give learning opportunity to every travel trip space travelers to feel that this space actual environment can bring what disadvantages or advantages to influence our earth when they are catching aircraft to fly to space to travel in every space trip. The space and earth learning knowledge can include these two aspects of space learning knowledge and experience below: On the teaching of space environment learning knowledge hand, the topics can include as below: Firstly the space learning topic can concern how space environment influences water and hydrated minerals change, they can learn what our drinking water function how is applied to space environment. For example, in the space environment, they can learn and attempt to feel that how water can be used in protecting astronauts against harmful radiation from the sun and cosmic rays by cloaking spacecraft with a thin layer of water in the actual space environment as well as the space travelers can also feel water is same as fuel when they are catching the spacecraft, they can feel the water is heavy to transport into space when they are catching the spacecraft to fly to space during their whole space tourism journey. Moreover, when their spacecraft reaches anyone of planets and it stays on the planet's space station, e.g. Moon space station. They can learn how to attempt to contact the hydrated minerals to learn and feel what they contained in some asteroids may be possible sources of water and fuel in the actual space environment. When they are walking in actual space environment, such as Moon planet, they can contact or touch this hydrated minerals to learn how water molecules can be extracted and separated chemically to produce hydrogen fuel knowledge in the actual space environment. This is one exciting space learning experience to the space travelling student passengers.Secondly the space learning topic can concern how human fights space threats, even when their whole space leisure journey, the space science teacher can let the space trip student passengers to feel that they are learning new space knowledge between the space science teacher and whose space trip student passengers. Such as how to protect our earth knowledge: Teaching them to know when will be threats to our earth from space. The space science teacher can explain how this space threating environment influences our life safety and let them to feel that a mass extinction can be triggered if an asteroid 10 kilometers across hit the earth. Even being the apex species in the food chain did not space carnivorous dinosaurs from such disaster, who knows if this terrifying scene won't happen before our eyes? So, the space travelers can image and feel how the space threating environment can influence their life safety in the actual space environment as well as the space science teacher can let whose space travelers to feel and image the actual earth disaster will possible happen suddenly to let they feel afraid in the actual space environment. Also the space science teacher can teach how our earth can fright the space stones attack to let the space traveler to know, when an impactor targets an asteroid for a controlled well-times wallop. The collision will change the asteroid's momentum, deflecting it from its original orbital path which intersects with that of the earth. So, at the moment, the space travelers can image they are a larger spacecraft near an asteroid which can also change the path. Given enough time, the gravitational pull from the spacecraft will be able to steer the asteroid away from the earth. So, every space traveler will feel that they are catching the spacecraft in the safe space environment to avoid the Earth disaster from space sudden unpredictable attack.
