The average American has three friends.
The friends: Curiosity Mars rover, Perseverance Mars rover, Ingenuity Mars helicopter.

Trump is saying the quiet part out loud: he sent a $20B taxpayer-financed bailout to help his far-right buddy Milei cling to power.

Meanwhile our government is shut down, public servants aren't getting paid & we're barreling toward a Trump-made health care crisis. Sounds like Argentina First to me.

Trump on Milei: "If he loses, we will not be generous with Argentina."

Whelp, survived the JPL layoffs. Thankful, but oof, we lost serious, irreplaceable talent. Call your Congress folks and let them know what an unforced error this was because of the current criminal administration who don’t have a 🤬 clue what this country does or can do.

If Mike Johnson is refusing to call the House back into session during the shutdown, then we’ll do the work right here the Bronx.

The New York Essential plan is being eliminated entirely next year due to the GOP healthcare cuts. People’s lives are at stake.

And that’s why we’re fighting back.

My internship at Goddard Space Flight Center was focused on assessing the effects of extreme urban heat on vulnerable populations. NASA research does so much for us here on Earth — but not without funding. 🧪

A lot of comments on Mars rovers or Moon landings, but it's important to remember that the planet NASA studies most is Earth. This is less about cutting flashy things like moonwalks and more about keeping communities in the dark on climate, weather, agriculture, pollution, natural hazards, and more.

That was too disgusting to finish, reading all the hyper-male 🤡💩 from our criminal president.

‪🆕 Researchers combed through images from ESA's #MarsExpress and #ExoMars spacecraft to find 1039 swirling dust devils 🌪️

Using these dust devils to track raging winds on Mars, their findings include that the strongest winds blow much faster than we thought!🧪🔭

This new catalogue of dust devils gives us a much clearer picture of the Red Planet’s weather and climate.

But besides pure science, it will also be useful for planning future missions, like dealing with the irksome dust that settles on the solar panels of our robotic rovers.

Western Alaska was hit hard by the recent storms. Houses floated away in Kipnuk, houses flipped over, people lost everything from the flooding that came with the storms. Please donate if you can. This group has a long history of supporting AK communities.

Hanging onto every bit of good news

The river has come alive in the Klamath with wild Chinook salmon. The wider ecosystem is healing.

This most powerful story of Indigenous-led #rewilding after the largest dam removal in US history keeps getting better.

Solar-powered airships for high altitude (18-20 km) long-endurance surveillance and early warning:

6 of these could cover the entire US east coast with 500 km range radar, but they'd need to be 185m long and generate 300 kW.
