Water on Mars–Where Do We Go From Here?

Water on Mars–Where Do We Go From Here? Today’s exciting NASA press briefing confirmed what we suspected: Mars has water flows, at least intermittently. Where water flows, there is a good possibility of life, but what exactly do these conditions signify? “Our quest on Mars has been to ‘follow the water,’ in our search for life in the universe, and now we have convincing science that validates what we’ve long suspected,” said John Grunsfeld, astronaut and associate administrator of NASA’s Science Mission Directorate in Washington. “This is a significant development, as it appears to confirm that water — albeit briny —...

BREAKING: Present-Day Running Water on Mars Confirmed!

Present-Day Running Water on Mars Confirmed As the European Planetary Science Congress 2015 (EPSC) prepares to start in Nantes, France, today, it quietly carries news that NASA may shout tomorrow at the Mars press briefing: present-day water flow has been confirmed on Mars! An abstract from the conference proceedings by Lujendra Ojha et al confirms spectral evidence for hydrated salts–briny, salty water–in four different locations on Mars. This work has been ongoing, and has been documented throughout its study by NASA. The dark, seasonal streaks, frequently growing on the warmer slopes of Martian craters, were long thought to possibly indicate water...

NASA Announcement on Mars Mystery

 NASA Announcement on Mars Mystery Upcoming Press Briefing NASA has scheduled a press briefing for Monday, 28 September 2015, to detail a “major science finding” about Mars. Is it confirmation of water on the planet? Microbial life? Or something more unexpected, perhaps concerning the spectacularly odd rock formations Mars claims? There has been much speculation on the nature of the finding, with everyone scrambling for clues from discussions of recent findings. Inverse agrees that the composition of the press briefing contingent may give a clue: it includes Dr. Alfred McEwen, the principal investigator of HiRISE (High Resolution Imaging Science Experiment), and...

Technical Overview: ‘Stonehenge’ Discovered on Mars?

‘Stonehenge’ Discovered on Mars? This year has seen an abundant amount of mysterious discoveries both here on Earth and in outer Space; from a Superhenge in Britain to countless geological formations of interest discovered across our tiny solar system. Recently, the internet has turned its attention to a peculiar grouping of rocks on the red planet which appear uncannily similar to the visible portions of the ever-famous Stonehenge back here on Earth. Mars anomaly hunters spotted what was subsequently dubbed as “Marshenge” in a photograph, estimated to have been taken by the HiRISE instrument on-board the Mars Reconnaissance Orbiter in the same grouping of photos listed on University...
