Journey into Space

Space Tourism• Orbital space

tourism opportunities have been limited and expensive, with only the Russian Space Agency providing transport to date.

Space tourism is space travel for recreational, leisure or business purposes. A number of startup companies have sprung up in recent years, such as Virgin Galactic and XCOR Aerospace, hoping to create a sub-orbital space tourism industry.

• Russia halted orbital space tourism in 2010 due to the increase in the International Space Station crew size, using the seats for expedition crews that would have been sold to paying spaceflight participants.Orbital tourist flights are planned to resume in 2015.

As an alternative term to "tourism", some organizations such as the Commercial Spaceflight Federation use the term "personal spaceflight". The Citizens in Space project uses the term "citizen space exploration".

As of September 2012, multiple companies are offering sales of orbital and suborbital flights, with varying durations and creature comforts

How much does it cost to go to space?

• The publicized price for flights brokered by Space Adventures to the International Space Station aboard a Russian Soyuz spacecraft have been US $20–40 million, during the period 2001–2009 when 7 space tourists made 8 space flights. Some space tourists have signed contracts with third parties to conduct certain research activities while in orbit.

• The company has already signed up more than 600 people who aim to fly to suborbital space aboard SpaceShipTwo, at a current price of$250,000 per seat. "For Galactic, 2015 is the year that we plan to go to space, and start operating commercialy," said Virgin Galactic CEO George Whitesides.

How much is a day on the moon?

• A day on the Moon lasts 29.5 of our Earth days. In other words, if you were standing on the surface of the Moon, it would take 29.5 days for the Sun to move entirely through the sky and return to its original position.

• Depends on where in space and the speed of the aircraft … The shortest trip to the Moon took place in January 2006 by the NASA Pluto probe New Horizons. With the speed of 58,000 km/hr, it only took 8 hours and 35 minutes to get to the Moon from Earth.

• Earth is the third planet from the Sun, the densest planet in the Solar System, the largest of the Solar System's four terrestrial planets, and the only astronomical object known to harbor life.

• According to evidence from radiometric dating and other sources, Earth was formed about 4.54 billion years ago.[ Earth gravitationally interacts with other objects in space, especially the Sun and the Moon. During one orbit around the Sun, Earth rotates about its own axis 366.26 times, creating 365.26 solar days or one sidereal year.
