Science: Life on Mars, ocean found, gases

Unveiling Mars: The Mysterious Ruins and the Quest for Ancient Life (MSN)
(Popular Mechanics) In its ancient past, Mars likely contained many of the necessary ingredients for microbial life to flourish on its surface. Now, a new discovery by NASA’s Perseverance rover shows a trifecta of compelling evidence — including the presence of water, organic compounds, and a chemical energy source — all on one rock located in the Jezero Crater.
Although this is the best clue yet that microbial life existed on Mars, there are still other explanations that could explain account for this geologic display without the existence of microbes.


“Is there life on Mars” is a question that has vexed astrobiologists and [Buddhist rockstar] David Bowie [who almost became a Vajrayana Buddhist monk rather than a human-alien hybrid pop singer] alike.

Playing with reptilian monsters on earth

While the latter imagined some macabre collection of arachnids on the Red Planet [Spiders on Mars], NASA scientists are fixated on finding evidence that microbial life once flourished on the fourth rock from the Sun.

They are so fixated, in fact, that the space agency has spent more than $5 billion getting two immensely complicated robotic rovers — Curiosity and Perseverance — onto the Martian surface with this specific microbial mission in mind.

Now, one of those rovers might have discovered one of the most compelling pieces of evidence for Martian microbial life.
Located on an arrowhead-shaped, three-foot-long rock nicknamed “Cheyava Falls” in the Jezero Crater (the 28-mile-wide crater that Perseverance has called home for the past three years), this “piece of evidence” is actually a trifecta of data points that suggest the presence of past microbial life.

The rock in question features two vertical veins of calcium sulfate that likely formed from past water, and these stripes both flank a red band of rock filled with “leopard spots.”

NASA has discovered evidence of past water on Mars before, but it’s this narrow band of rock that brings new meaning to this discovery.

Using its SHERLOC (Scanning Habitable Environments with Raman & Luminescence for Organics & Chemicals) and PIXL (Planetary Instrument for X-Ray Lithochemistry) instruments, Perseverance determined the existence of organic compounds within the rock.

What's in Area 51, Groom Lake, Dreamland?

Oh, and those “leopard spots?” Those likely indicate chemical reactions that could’ve supplied energy to ancient microbial Martians.

While each of these discoveries — the presence of water, organic compounds, and chemical reactions — would be notable even if discovered separately, NASA has never seen all three in one location, meaning the geological chemistry of Cheyava Falls is possibly our best clue yet that Mars once hosted life.

Partner Yoga, Monday nights in L.A.

Holly in Partner Yoga with Anthony
Weekly Partner Yoga classes are taught by Holly every Monday night at 7:30 pm at Kinship Yoga in Highland Park.

What would be better to develop skill in yoga than sharing the practice with a partner? Develop balance, enthusiasm, strength, and trust twice as fast as trying to go it alone. Partner yoga goes deeper than a solo practice can get, and with guided Thai yoga massage, each partner will be happy to have participated.

Grab a friend, relative, or even a romantic partner to be introduced to the most intimate of all yoga styles. These modalities help develop awareness, strength, flexibility, and relaxation. Mutual practice also encourages trust and communication.

What is "Partner Yoga" between friends?
Classes begin with light partner stretching, using one another to assist in simple poses. The Partner Yoga naturally progresses into fun exercises, organically evolving into some acrobatics in a fun and safe way.

The session is completed with a cool down of assisted Thai Yoga, diving deep into a full body relaxation with some caring massage techniques.

The session is 90 minutes. Bring a mat, BUT a partner is not required. One will be assigned. Prior sign up online is encouraged:

Climbing Mount Rainier with a guide Disappointment Cleaver Route
(Helen and Tim Travel)  Ever wonder what it's like to climb Mount Rainier with a guide service? Join us as we climb Mt. Rainier with RMI Guides. We signed up for an end-of-July 4th day climb to summit the tallest mountain in the state of Washington, USA. Find out if we made the summit.

ABOUT: Welcome! We’re Helen and Tim Travel, a husband and wife duo with a goal to see the world one mountain at a time. We live in the PNW and enjoy all outdoor adventures. On the weekends, we can be found on the mountains, the sea, or somewhere on a hiking trail.

Forecast: manmade drought to continue (video)

Associated Press (ap.org); Crystal Quintero, Seth Auberon (eds.), Wisdom Quarterly

Sandbars fill the Rio Grande north of Albuquerque, N.M. Forecasters said April 23, 2018, that drought conditions across southwestern states are contributing to a wildfire threat.
After brief relief, forecasts indicate drought will continue


Dry weather will prolong the wildfire threat through summer in the Southwestern US, even though weekend showers temporarily relieved drought conditions in parts of the area, forecasters said today.


The drought is rooted in a dry spell that began in October and is considered "extreme" from southern California to central Kansas.

Conditions are even worse in the Four Corners region and the Oklahoma and Texas panhandles, warranting their description as "exceptional."

"The proverbial spigot shut off," said Brian Fuchs, a climatologist at the National Drought Mitigation Center at the University of Nebraska in Lincoln. "Drought isn't necessarily a signal for wildfires, but it can exacerbate the conditions that do take place." More
