Hopefully that RTG will make sure we get a nice, long life out of it

Whoa.. New Perseverance's Mastcam HI-RES panorama image is out

Perseverance's Mastcam-Z First High-Resolution Panorama - NASA Science

Stitched together from 79 individual images, this Mastcam-Z right-eye 110-mm zoom mosaic is from the camera's first high-resolution panorama imaging sequence.

The asteroid Apophis is due to make a close approach to Earth this week, and scientists are preparing to observe the flyby.

The space rock, thought to be between 310 and 680 meters (1,017 ft to 2,230 ft) in diameter, is going to coast past the Earth at 8:15 p.m. ET on March 5. It will pass at a distance of around 10,225,000 miles—equivalent to around 43 times the distance from the Earth to the moon. The distance may seem large, but it is small in astronomical terms.

God of Chaos Asteroid to Pass Earth This Week Before 2029's Close Approach

Apophis is deemed potentially hazardous because of its size and occasional proximity to our planet.

Can't wait to see the helicopter fly. When the rover deploys that little helicopter, it's like it's laying a robot egg.

Experts recreate a mechanical Cosmos for the world’s first computer

Researchers at UCL have solved a major piece of the puzzle that makes up the ancient Greek astronomical calculator known as the Antikythera Mechanism, a hand-powered mechanical device that was used to predict astronomical events.

Just shows that throughout history we sure have had some geniuses to balance out the fools. What a piece of engineering that is.

An Gigapixel image of milkyway by Finnish hobbyist astrophotographer. Project took only 12 years

Milky Way, 12 years, 1250 hours of exposures and 125 x 22 degrees of sky

This blog is all about astrophotography and it works mainly as an imaging diary. J-P Metsavainio is a Finnish astrophotographer,

Wow, thanks for sharing that. What an impressive image. To think in those 12 years from start to finish, so many things change. Especially technology. It's impressive that the tech that he started using 2014 he was able to use up to the end and not have something that was outdated. The crossover from 2009 to 2014 tech must also of been seamless. And the result is just amazing.

Yeah, final mosaic image is 100 000 pixel wide.. Just wondering the size of file in Mb

 

[CurtisOliver]

Well, at 100000 pixels wide and a ratio of 125:22 that would make the image 17600 pixels tall.
100000*17600=1760000000 or 1760 MP / 1.76 GP!!!
In lossless JPEG form that would be a single 2.64 GB image apparently.
Crazy

Even more impressive is that the image is so large that a 10 DPI billboard would be as large as 254m x 44.7m

For anyone who would like to learn more about space, the universe, and everything in it I suggest you check out the PBS Space Time youtube channel with Dr. Matt O'Dowd, I highly recommend it!

Can a full rez image be downloaded? I can't seem to find it there, I can only find one that can only be zoomed in on a bit before it gets pixelated?

A 2.65GB size image would be fine as I have many terabytes of storage space...

 

[CurtisOliver]

It looks like he is reserving his best copy so he can sell prints. The 7000x1300 pic is very impressive in its own right. Just it is 193.4x smaller than the full size picture.
