You’re in a spacecraft, on a mission to land on the moon for the first time in history, and the microphone to Earth is off. What do you say?

The 12 scientists and support staff made a slow crawl across a vast, blank stretch of East Antarctica this past austral summer for three months to study how regional climate variability relates to global climate change expected to encounter brutally cold storms and other challenges on the high polar plateau.

A team of researchers from the CSIC-INTA Astrobiology Centre in Madrid has confirmed that the type of mineralogical composition on the surface of Mars influences the measuring of its temperature.

The Review of U.S. Human Space Flight Plans Committee will hold three public meetings July 28-30. The meetings are open to news media representatives. No registration is required, but seating is limited to location capacity.

Venus Express has charted the first map of Venus’s southern hemisphere at infrared wavelengths. The new map hints that our neighbouring world may once have been more Earth-like, with both, a plate tectonics system and an ocean of water.

The outcome of the bilateral meeting was an agreement to create a Mars Exploration Joint Initiative (MEJI) that will provide a framework for the two agencies to define and implement their scientific, programmatic and technological goals at Mars.

According to findings from the Phoenix Mars Lander mission, snow and water-ice clouds play a crucial role in the exchange of water between the atmosphere and surface of Mars, which suggests that Mars is even more like Earth than previously thought.

NASA astronaut Jose Hernandez, set to fly aboard space shuttle Discovery in August, is providing insights about his training on Twitter in both English and Spanish. It will be the agency’s first bilingual Twitter.

Favorable chemistry and episodes with thin films of liquid water during ongoing, long-term climate cycles may sometimes make the area where NASA’s Phoenix Mars mission landed last year a favorable environment for microbes.
