ISRO prefers woman fighter test pilots or female scientists for its much-awaited human space flight programme Gaganyaan mission and it is possible to send them in the future, the space agency chief S Somanath said on Sunday.

He also said ISRO would send a female humanoid - a robot that resembles a human - in its unmanned Gaganyaan spacecraft next year. The ambitious mission aims to send humans into space on a Low Earth Orbit of 400 km for three days and bring them safely back to the Earth.
