Where is space exploration headed

During the s, NASA also carried out Project Viking in which two probes landed on Mars, took numerous photographs, examined the chemistry of the Martian surface environment, and tested the Martian dirt called regolith for the presence of microorganisms.

Since the Apollo lunar program ended in , human space exploration has been limited to low-Earth orbit, where many countries participate and conduct research on the International Space Station. However, unpiloted probes have traveled throughout our solar system. In recent years, probes have made a range of discoveries, including that a moon of Jupiter, called Europa, and a moon of Saturn, called Enceladus, have oceans under their surface ice that scientists think may harbor life.

Meanwhile, instruments in space, such as the Kepler Space Telescope , and instruments on the ground have discovered thousands of exoplanets, planets orbiting other stars.

This era of exoplanet discovery began in , and advanced technology now allows instruments in space to characterize the atmospheres of some of these exoplanets. Also called an extrasolar planet.

Others say paying for human space flight pumps money into the economy, arguing that spin-off companies from space research and a growing commercial space industry generates seven to 14 times the cost of missions. And Nasa, the most significant global player, is not spending nearly as much as it used to. The first space race was part of the chest-beating of the cold war, but since then human space exploration has been more about countries working together than against each other.

A big exception to this is China, which has gone it alone with its space ambitions, never sending an astronaut to the ISS. However, the future of any effective human space flight is certainly likely to be cooperative rather than antagonistic. Since , national spaces agencies in 14 countries have attempted to coordinate their dreams into a single vision. To get to Mars, most people in the human space flight community feel we need to first go back to the moon.

The moon has several advantages. From their celestial laboratory, scientists could study the impact of radiation exposure and near-weightlessness on the body at a closer distance to Earth, but still within deep space, all while preparing for trips further afield.

Not quite either. The Global Exploration Roadmap suggests first building a space station as an orbital base from which to send astronauts back and forth to the moon. This will look similar to the ISS except, instead of rushing around the Earth, it will orbit the moon.

It is a mammoth feat and it would be wise to expect serious delays. If you read the policies, it is clearly a long-term vision without a date. But we probably are still lacking the technology to keep people for a long time in deep space. The US and Russia have been giving way to new players.
