Protecting astronauts from cosmic radiation is one of the key challenges facing future missions to Mars, and Nasa believes it may have a solution.
The space agency, which is planning to send explorers to the red planet in the 2030s, is considering the use of drugs that alter the DNA code of its crews.
One of the techniques currently under development that it is following is NMN, a compound expected to enter clinical trials after it was shown to rejuvenate elderly mice in laboratory tests.
It is also considering making more advanced tweaks or alterations to the DNA of its astronauts, although the moral implications of such a radical step will need to be addressed
Using such a technique would allow Nasa's scientists to turn up the volume on one genetic instruction or mute another.
This may help to prevent cancers, dementia and other radiation related illnesses from developing, as well as boosting the body's resilience to its effects.
