Latest Chris McKay Stories
NASA's Phoenix Mars Lander discovered a surpise chemical in 2008, which suggests that carbon-based chemicals found in 1976 by Viking Mars landers could be from the Martian soil and not from cleaning fluids.
Searching for clues to the potential for life on Mars, NASA scientists recently explored microbial communities in some of the worldâ€™s oldest, driest and most remote deserts, in Chinaâ€™s northwest region, and found evidence suggesting that conditions there may be similar to those in certain regions of Mars.
The launch of the Mars Phoenix Lander is just a year away. The spacecraft will be aiming for the martian north pole, and if it lands successfully it will dig in snow and ice in one of the few places on Mars where scientists think life could be preserved.
Chris McKay, a planetary scientist at NASA Ames Research Center, recently gave a public lecture, sponsored by the Planetary Society, about what scientists have learned about Titan from the Huygens probe. In this, the final part of a four-part series, McKay talks about the unsolved mystery of Titan's ice rocks.
Saturn's moon Titan is notable both because it is the largest moon in our solar system and because it is the only moon in the solar system with a significant atmosphere. Early this year, NASA's Cassini orbiter, currently orbiting Saturn, released the European Space Agency's Huygens probe, which descended through Titan's atmosphere and landed on the moon's surface. Recently, Chris McKay, a planetary research scientist at NASA Ames Research Center, gave a public lecture, sponsored by the...
Earth, Mars and Venus all have greenhouse effects. So does Saturn's giant moon Titan. But unlike any other world in our solar system, Titan also has an anti-greenhouse effect. Recently, Chris McKay, a planetary research scientist at NASA Ames Research Center, gave a public lecture, sponsored by the Planetary Society, in which he talked about the scientific results of the Cassini-Huygens mission to Saturn and Titan. In this, the third in a four-part series, McKay explains why Titan's...
Planetary scientist Chris McKay asks one of the most interesting questions in astrobiology: how would one know an organic relic when it appears?
Planetary scientist Chris McKay describes one of the driest place on Earth and how one might test for the equivalent of a bacterial 'treeline', a region so harsh in the Andes Mountains where even microbes cannot thrive.
