Mars or the Red planet is 5.46 crores kilometers away from Earth. You can compare this with the distance from Earth to the moon, which is only about 3,84,400 km.
NASA has planned to send humans to the Mars in the 2030s. Preparations for that journey are already well under way. NASA is developing the capabilities needed to send humans to an asteroid by 2025 and Mars in the 2030s.
After the Earth, Mars is the most habitable planet in our solar system due to several reasons:
It is believed that it’s soil contains water to extract
It isn’t too cold or too hot
Gravity on Mars is 38% that of our Earth's, which is believed by many to be sufficient for the human body to adapt to
It has an atmosphere that offers protection from cosmic and the Sun's radiation
The day/night rhythm is very similar to ours here on Earth: a Mars day is 24 hours, 39 minutes and 35 seconds
For decades, the agency and its partners have sent orbiters, landers and rovers, dramatically increasing our knowledge about the Red Planet and paving the way for future human explorers. The Curiosity rover has gathered radiation data to help us protect future astronauts, and the upcoming Mars 2020 rover will study the availability of Martian resources, including oxygen.
International Space Station
Astronauts on the International Space Station are helping us prove many of the technologies and communications systems needed for human missions to deep space, including Mars. The space station also advances our understanding of how the body changes in space and how to protect astronaut health.
Asteroid Mission in 2020s
Our next step is deep space, where NASA will send a robotic mission to an asteroid. Astronauts aboard the Orion spacecraft will explore the asteroid in the 2020s, returning to Earth with samples. This experience in human spaceflight beyond low-Earth orbit will help NASA test new systems and capabilities, such as Solar Electric Propulsion, which we’ll need to send cargo as part of human missions to Mars.
Indian Woman in Mars Mission 2030
After Kalpana Chawla, Jasleen Kaur Josan has become the 2nd Indian Woman and first Sikh women to be selected by NASA for the Mars Expedition happening in 2030. The Orion Mission will be the first man mission to Mars, which is on track to take place in 2030. Born in Kurukshetra, Haryana, Jasleen Kaur Josan is now based in Huntsville, Alabama. She is pursuing an integrated degree of master and Ph.D in space science from the University of Alabama.
