NASA's historic Mars helicopter Ingenuity grounded for good after 72 flights

NASA said on Thursday its Mars robot helicopter Ingenuity, the first vehicle to achieve powered, controlled flight on another world, has been grounded for good after flying dozens of times over three years, ending a landmark mission that far exceeded all expectations. The fate of Ingenuity was...

Most of their equipment up there has issues eventually with Martian dust covering the solar panels - I'm surprised that a the helicopter kicking up dust lasted as long as it did.
 
The "Night Sky" during the day...

2024 will see 2 High Priority Bucket List Items ticked off, and only one of them involves a few hours of travel. Fortunately we'll be going "upta Camp" with friends who's house is in the "Totality" bullseye for the eclipse.

Even if we get rained/clouded out, normal April Maine Weather, it will definitely be cool to watch it become night at 15:30 EDT. You folks can "shuffle off to Buffalo" for a peek!!

The other Bucket List item is 5400 miles from here and current international conditions may force us to cancel... :(

Saturn's 'Death Star' moon has a hidden secret - a subsurface ocean​


WASHINGTON (Reuters) - Saturn's moon Mimas is known for its uncanny resemblance to the dreaded Death Star in the original "Star Wars" movie. But it has another intriguing distinction as well, according to researchers - a subsurface ocean hidden under its icy and crater-scarred outer shell.

Astronomers said on Wednesday that data obtained by NASA's Cassini spacecraft on the rotational motion and orbit of Mimas confirm the presence of an ocean of liquid water beneath an ice layer 12-19 miles (20-30 km) thick. This ocean, they said, appears to have formed recently, in cosmic terms - less than 25 million years ago and likely between 5 and 15 million years ago.


The findings make Mimas a compelling site for exploration into the conditions that could lead to the formation of life, considering Earth's first living organisms arose in our planet's primordial seas billions of years ago.

As I posted above, I have very little expectation of clear skies for the eclipse. Anyone who knows Maine April weather should expect clouds that day. Now, multiple media outlets are showing historical data for cloud cover. Maybe I'll try to find a Sacrificial Virgin to offer up to Zeus for clear skies, but the sourcing and/or the offering will probably be met by deaf ears...

Marker on map below is where we will be on April 8th...

so the excrement will be that a speck of light as bright as the north star will be visible where usually, no star isS visible?

We have many folks around here who like to channel Shakespeare, Much ado about nothing. I bet few, if anyone, will be looking to see this supernova. I will, just for giggles so I can knock "Supernova sighting" off the astronomy bucket list...

Now if this supernova was in our galaxy, it would definitely be an event. The Crab Nebula, M1, is the remanent of a supernova. The star that created the Crab Nebula exploded in 1054 when it was recorded as a "guest star" in the sky by Chinese astronomers. Even non-astronomers probably noticed its appearance, since the supernova explosion was so bright it was comparable to the full moon, six times brighter than Venus. That was probably something people could see during the day. I've seen Venus during the day when she's at her brightest, just have to know where to look.

But that's nothing, SN 1006 was a supernova that is likely the brightest observed stellar event in recorded history, reaching an estimated −7.5 visual magnitude, and exceeding roughly sixteen times the brightness of Venus. That's something ANYONE could see during the day.

FYI, in star magnitude talk, MINUS numbers are brighter than positive ones. Polaris, the North Star, has a magnitude of 1.98...

Explosive green 'Mother of Dragons' comet now visible in the Northern Hemisphere

The green comet 12P/Pons-Brooks is now visible in the night sky in North America. Here's how to see it.
www.yahoo.com www.yahoo.com

A rare, formerly-horned comet that astronomers have dubbed the "Mother of Dragons" is now visible after dusk in the Northern Hemisphere.

This "Halley-type" comet, officially known as Comet 12P/Pons-Brooks, completes a single orbit around the sun once every 71 years. The last time it passed by Earth was in 1954, according to a statement from the European Space Agency (ESA).

The city-size comet has a nucleus measuring 10.5 miles (17 kilometers) wide and orbits the sun in an elliptical shape. Recent observations of the comet have revealed a hidden spiral of light surrounding its frigid heart.
 
this just seems like it is something we SHOULD be funding.......................

What Happens When NASA Loses Eyes on Earth? We’re About to Find Out.

Sometime in the next few years — no one knows exactly when — three NASA satellites, each one as heavy as an elephant, will go dark. Already they are drifting, losing height bit by bit. They have been gazing down at the planet for over two decades, far longer than anyone expected, helping us...

After living in Maine for 15 years, tonight we had the Perfect Solar Storm, that is great solar activity on a early new moon, cloudless night. So guess what we saw for the first time??

It started humbly...

Here's a video. I've brightened it as far as possible so make sure you watch it in dark surroundings. Was very cool to see the Aurora "dance"
