The effect of
long - term travel in interplanetary space is unknown, but scientists estimate an added risk of between 1 % and 19 % (one estimate is 3.4 %) for men to
die of cancer because of the radiation
during the
journey to Mars and back to Earth.
And yet more PS4 exclusives appeared: famed game maker Suda51's Let It
Die, a bloody brawler launching in 2015; Giant Squid's Abzu, an underwater tapestry from the artist who created the beautiful
Journey; a
long - awaited re-release of Tim Schafer's beloved PC adventure game Grim Fandango; and No Man's Sky, a gorgeous space exploration game that debuted
during last December's Spike TV VGX broadcast.
