That is the inquiry confronting the NASA group answerable for assembling the destinations for 2020 wanderer mission to Mars.

"We're still on the journey to answer the terrific inquiry: Is there life some place else in the universe?" John Grunsfeld, NASA's copartner director for science, told news people Tuesday in a video chat.

Past missions to Mars have discovered absolute signs that water once streamed in a cavity and rock examines that hint at earth minerals.

"We truly would have been wise to about-face to the surface, and head off to the following stage. ... Did Mars ever have life?" Grunsfeld said as he saw a 160-page report ready by the Mars 2020 Science Definition Team, an assembly collected by NASA to diagram the targets of the mission.

As a major aspect of the readiness for the mission, NASA plans to direct an open rivalry. It is arranged by NASA for the space innovation and deductive instruments that will be conveyed by the meanderer and utilized as a part of the mission, consistent with the report.

Notwithstanding the 2020 mission, NASA is planned to start the Mars Atmosphere and Volatile Evolution mission in November 2013. That mission is situated to investigate the mixes of the Martian climate, which researchers say will offer a sight into the planet's atmosphere and tenability.

In 2016, a joint effort between the European Space Agency and Russian Federal Space Agency is relied upon to start an Exomars Trace Gas Orbiter --a mission to guide methane and different gases on Mars.

The European and Russian space organizations want to start the Exomars wanderer in 2018.

"What we have through the following 10 years is an exceptionally complete arrangement of universal missions to Mars," said Jim Green, executive of NASA's Planetary Science Division in Washington.
