Mars is still a distant objective and space agencies need to make major advances in technology before they're ready for the red planet. More and more experts are suggesting a stopover at the moon is the necessary next step to develop the technology and experience required for Mars. Plans for Nasa's Lunar Gateway are already in the works. It'll likely be similar to the International Space Station but orbiting the moon instead. At only three days away from the Earth, a lunar space station could become the mid-point between the Earth and Mars to stock supplies. The station could also serve as a training site for astronauts to prepare for the long journey to Mars.
India could be only fourth to send humans to spaceOnly three countries currently have active human space programmes: US, Russia and China. But new nations, including Japan, Iran and Malaysia, are entering the space race. India has set its sights on a 2022 manned mission into space aboard the Gaganyaan.
Up to$82 million for a space trip
Nasa's space shuttle programme started in the 1970s, cost $209 billion or nearly $1.6 billion per flight. Most astronauts headed to space use the Russian Soyuz spacecraft. Russia sells round-trip rides for anywhere between $21 million and $82 million.
