There's Water on Mars. We'll Harvest Oxygen From It.
This development could lead to resources that may benefit future expeditions.
NASA has been teasing us with a “big announcement” concerning Mars since last week. This morning we got our answers. A team of researchers confirmed the Mars Reconnaissance Orbiter (MRO) has found water.
After years of methodical study, researchers noticed dark streaks appearing on the slopes of Mars. These streaks seemed to ebb and flow during the warmer seasons on the red planet, indicating water.
“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, Associate Administrator of NASA’s Science Mission Directorate in Washington, in a press release. “This is a significant development, as it appears to confirm that water — albeit briny — is flowing today on the surface of Mars.”

This development could lead to resources that may benefit future expeditions. The water itself is pretty salty, saltier than the world's oceans, according to scientist Alfred McEwen. The researchers estimate at least 100,000 cubic meters of water. But it's wet soil, rather than standing water, which means researchers will have to develop ways to extract it from the ground.
However, it seems NASA's researchers are already on it — developing some "MacGyver" solutions to prepare for a Mars mission: Diane Linne, a senior research engineer at NASA’s Glenn Research Center, demonstrates one such solution in how astronauts might harvest oxygen on Mars.
This will help in our ultimate goal to become a space-faring species, which is necessary for the long-term survival of the human race, according to Stephen Petranek, author of How We'll Live on Mars.
Famous physicists like Richard Feynman think 137 holds the answers to the Universe.
- The fine structure constant has mystified scientists since the 1800s.
- The number 1/137 might hold the clues to the Grand Unified Theory.
- Relativity, electromagnetism and quantum mechanics are unified by the number.
Younger Americans support expanding the Supreme Court and serious political reforms, says new poll.
- Americans under 40 largely favor major political reforms, finds a new survey.
- The poll revealed that most would want to expand the Supreme Court, impose terms limits, and make it easier to vote.
- Millennials are more liberal and reform-centered than Generation Z.
A 2020 study published in the journal of Psychological Science explores the idea that fake news can actually help you remember real facts better.
- In 2019, researchers at Stanford Engineering analyzed the spread of fake news as if it were a strain of Ebola. They adapted a model for understanding diseases that can infect a person more than once to better understand how fake news spreads and gains traction.
- A new study published in 2020 explores the idea that fake news can actually help you remember real facts better.
- "These findings demonstrate one situation in which misinformation reminders can diminish the negative effects of fake-news exposure in the short term," researchers on the project explained.

How does misinformation spread?

Research on this effect (referred to as "continued-influence") has shown that information presented as factual that is later deemed false can still contaminate memory and reasoning. The persistence of the continued-influence effect has led researchers to generally recommend avoiding repeating misinformation. </p><p>"Repetition increases familiarity and believability of misinformation," <a href="https://engineering.stanford.edu/magazine/article/how-fake-news-spreads-real-virus" target="_blank" rel="noopener noreferrer">the study explains</a>.</p><p><strong>What is the "familiarity-backfire" effect?</strong></p><p>Studies of this effect have shown that increasing misinformation familiarity through extra exposure to it leads to misattributions of fluency when the context of said information cannot be recalled. <a href="https://journals.sagepub.com/doi/10.1177/0956797620952797#" target="_blank" rel="noopener noreferrer">A 2017 study</a> examined this effect in myth correction.
