Sadocus asperatus (on the left) and Pachylus chilensis (on the right) from Chile are one of the most archaic inverts around! They belong to Opiliones, an order of arachnids colloquially known as harvestmen, harvesters, or daddy longlegs.

Three countries are due to reach Mars in the next two weeks

A small fleet of spacecraft from the United Arab Emirates, China, and the United States will reach Mars this month after launching from Earth last year. The march to the Red Planet marks a marathon of firsts: it’s the UAE’s first foray into deep space, China’s first independent attempt to land on Mars, and NASA’s first shot at deploying a Martian helicopter.

The first image of Mars captured by China’s Tianwen-1 probe on February 5th, 2021.

While each mission has its own individual milestones, the fleet of spacecraft is collectively opening a new era in Mars exploration. With the arrival of these missions, the hunt for signs of off-world life is in full force. UAE, China, and NASA are all racing to gain a better understanding of a world believed to have held life at some point in the distant past or possibly in the present. With Tianwen-1 analyzing potential subsurface lockers of ancient life, Hope scanning the Martian atmosphere, and Perseverance scooping up dirt samples for retrieval, an answer could come soon, Nye said.

“What are the chances that someday evidence of life will be found there?” Nye said. “Very high.”

European-crafted glass beads found at three different indigenous sites in northern Alaska date back to the pre-colonial period of North America, in what is an intriguing archaeological discovery.

No that lizard didn't get caught running down the wall. It was snare on the ground and the spider used a web pulley system to hoist it up like that!

descent images, video and audio is still pending uplink as the rover hasn't unfolded it's high gain antenna yet so can't transmit that data back yet

Watch the NASA Perseverance Mars rover landing in this incredible video

https://www.slashgear.com/watch-the-nas ... -22660512/

I cannot believe that video is real... I know the second video, with the drone, isn't... I'm not saying NASA is lying, it's just that the video looks incredibly good... I know it's not real time, and a computer may have "enhanced" it, but still.

Now I want to see video from the drone

How NASA’s Evolutionary Xenon Thruster (NEXT) works. An Ion thruster creates thrust by accelerating ions using electricity.

It's weird how lava looks lightweight, thinking about the fact that it's liquid rock.

They sent a robot to mars, and it used a cellphone to take vertical video

Actually, the point is it recorded SOUND FROM MARS

The person who posted that didn't include a link to the source, but I did see an announcement it was coming, so it must be real.

I found this official source

https://www.nasa.gov/press-release/nasa ... rst-audio/

edit

The samples in the NASA link sound totally different than the video. Please note that the second recording filters out noise from the rover.
