Opportunity, now moving to another target 1.5 miles away, has found evidence of drinkable water on Mars.
Opportunity, now moving to another target 1.5 miles away, has found evidence that some of the water on Mars was once drinkable.
Before trekking off last month, Opportunity used a grinder to scrape away the top layer of a light-colored rock for a peek inside. The rock was so lumpy and covered with crud that it took the rover several tries to crack open its secrets. Unlike other rocks that Opportunity inspected during the past nine years, the latest told a different story: It contained clay minerals, a sign that water coursed through it, and formed in an environment that might have been suitable for microbes. Previous rock studies by Opportunity pointed to a watery past on Mars, but scientists said the water was acidic.
“This is water you can drink,” said mission chief scientist Steve Squyres of Cornell University.
More details here, noting that this water comes from an earlier time on Mars, when the planet’s environment was more benign.
So the rover has now sampled both sides of the momentous planetary transition from a wet, benign environment more than 4 billion years ago to a colder, drier, harsher one since then
Readers!
My annual February birthday fund-raising drive for Behind the Black is now over. Thank you to everyone who donated or subscribed. While not a record-setter, the donations were more than sufficient and slightly above average.
As I have said many times before, I can’t express what it means to me to get such support, especially as no one is required to pay anything to read my work. Thank you all again!
For those readers who like my work here at Behind the Black and haven't contributed so far, please consider donating or subscribing. My analysis of space, politics, and culture, taken from the perspective of an historian, is almost always on the money and ahead of the game. For example, in 2020 I correctly predicted that the COVID panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Every one of those 2020 conclusions has turned out right.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.
3. A Paypal Donation or subscription:
4. Donate by check, payable to Robert Zimmerman and mailed to
