Mars loses water to space during warm, stormy seasons

Mars loses water to space during warm, stormy seasons

Science
Jan. 10 (UPI) -- All kinds of geological formations on Mars, alluvial fans, dry lake beds and eroded river valleys, suggest the Red Planet once hosted an abundance of water. Today, the water is mostly gone. What's left is largely locked up in the planet's polar ice caps. Scientists have been trying to figure out where all the water went and how fast it disappeared. New research, published this week in the journal Science, suggests Mars' seasonality may have dictated the rate at which water vapor was able to escape from the atmosphere and into space. In addition to the water trapped in the Red Planet's ice caps, trace amounts of water vapor persist in the Martian atmosphere. If these tiny water crystals rise high enough into the atmosphere, they can dissipate into space. To better underst...

New engine tech that could get us to Mars faster

Science
If we're ever to make regular journeys from Earth to Mars and other far-off destinations, we might need new kinds of engines. Engineers are exploring revolutionary new technologies that could help us traverse the Solar System in much less time.Because of the orbital paths Mars and Earth take around the Sun, the distance between them varies between 54.6 million km and 401 million km. Missions to Mars are launched when the two planets make a close approach. During one of these approaches, it takes nine months to get to Mars using chemical rockets - the form of propulsion in widespread use.That's a long time for anyone to spend travelling. But engineers, including those at the US space agency (Nasa), are working with industrial pa...

Nasa probes oxygen mystery on Mars

Nasa probes oxygen mystery on Mars

Science
The oxygen in Martian air is changing in a way that can't currently be explained by known chemical processes.That's the claim of scientists working on the Curiosity rover mission, who have been taking measurements of the gas.They discovered that the amount of oxygen in Martian "air" rose by 30% in spring and summer.The pattern remains a mystery, but researchers are beginning to narrow the possibilities.While the changes are most likely to be geological in nature, planetary scientists can't completely rule out an explanation involving microbial life.The results come from nearly six Earth years' (three Martian years') worth of data from the Sample Analysis at Mars (Sam) instrument, a portable chemistry lab in the belly of the Curio...

China has invited observers to a test of its Mars lander as it pushes for inclusion in more global space projectsBy SAMUEL McNEIL Associated PressNovember 14, 2019, 8:01 AM3 min read China invited observers to a successful test Thursday of its Mars lander as the country pushes for inclusion in more global space projects. The demonstration of hovering, obstacle avoidance and deceleration capabilities was conducted at a site outside Beijing simulating conditions on the Red Planet, where the pull of gravity is about one-third that of Earth. China plans to launch a lander and rover to Mars next year to explore parts of the planet in detail. China's burgeoning space program achieved a lunar milestone earlier this year by landing a probe on the mysterious far side of the moon. It has developed r...
