Water ice found near Mars’s equator could entice colonists and life-seekers

Science (8/16): Based on re-assessed data from NASA’s Mars Odyssey, which has been orbiting Mars since 2001, scientists believe there is ice in the subsurface near the Martian equator. It’s a finding, reported in the journal Icarus that could provide a water resource for future human explorers. It also contributes to discussions over possible Martian life and red planet climate change.

Mars sample return: Scientists debate how to bring Red Planet rocks to Earth

Space.com (8/16):  NASA’s upcoming Mars 2020 mission, a rover like Curiosity that would reach the red planet’s surface in February 2021, is to collect, preserve and cache samples of soil and rock for eventual return to Earth. The journey back to Earth becomes complex, requiring a Mars Ascent Vehicle, time in Mars orbit and a journey back that could include a stop at a lunar orbiting Deep Space Gateway. There astronauts could accompany the samples back to Earth aboard an Orion capsule, all in an effort to determine if Mars hosts or once hosted some form of life.

Why NASA is sending bacteria into the sky on balloons during the eclipse

Verge (8/15): Dozens of high altitude balloons are to soar Monday, August 21, during the rare total solar eclipse. Riding along will be samples of bacteria. Can they survive at altitudes of up to 100,000 feet? The answer may help to explain if the microbes could survive on Mars as well. Temperatures and solar radiation exposures will be a close match.
