Next week, Planetary Society members will be in Washington, D.C., walking the halls of Congress to defend NASA science and tell their representatives why NASA matters to them. The proposed FY2027 budget would cut the Science Mission Directorate by nearly half. Here's how to get involved: planetary.org/action-center

The Integrity spacecraft just entered the lunar gravitational sphere of influence, at 0438 UTC Apr 6. Wiseman, Glover, Koch and Hansen are now the 25th to 28th humans to have left terrestrial space.

The White House budget office just announced their proposal to cut NASA Science by 47% in FY 2027, as the Artemis II astronauts are on their way around the Moon.
Here’s our statement and what you need to know: planetary.org/press-releases…

We see our home planet as a whole, lit up in spectacular blues and browns. A green aurora even lights up the atmosphere. That's us, together, watching as our astronauts make their journey to the Moon.

From about 8 to 9 o'clock, a large brown landmass is Africa, with the Iberian peninsula twinkling with lights just where the planet curves. At the 1 o'clock spot, aurora glow in a thin green glow, just barely separated from the planet's surface. Earth is set against the black of space. Credit: NASA/Reid Weisman

A 2.5-second rocket flight that heralded decades of discovery in space!
Today marks 100 years since the first successful test of a liquid-fueled rocket. Robert H. Goddard's achievement would have appeared unimpressive by most measures: His rocket flew just 41 feet in the air, landing in a nearby cabbage patch. Liquid-propelled rocketry has been the backbone of spaceflight ever since.

A wooden door is propped up at an angle next to the frame where Goddard\u2019s assistant, Henry Sachs, later sheltered after lighting the rocket.

IT IS OFFICIAL! The President just signed the H.R. 6938 budget bill securing NASA funding in 2026 🎉 It is officially law, meaning that we successfully defeated the budget cuts in FY 2026. There’s still a lot of work to do, but let’s celebrate this collective accomplishment!
Advocacy works! I'm proud of the work we did, and pleased to see the results – at Emeryville, CA
You just saved NASA science. 👏
Congress just overwhelmingly passed a bill that protects NASA’s science programs and the National Science Foundation.
It rejects a proposal to cut NASA science by nearly half and cancel more than 40 missions.
This win is so important as the last year did real damage.
Over 4,000 NASA civil servants were lost, along with thousands of contractors.
Research was disrupted.
Grants were cut.
Mission teams were forced to plan shutdowns instead of doing science.
Students and early-career researchers lost critical opportunities.
But Americans (and international friends who care deeply about NASA) didn’t stay quiet.
➡️ You signed letters.
➡️ You shared posts.
➡️ You talked to friends and coworkers.
➡️ During our Day of Action this past October, hundreds of advocates showed up to meet with members of Congress and their staff. Tens of thousands of people from every state also contacted Congress, where nearly 100,000 messages were sent.
All that led to Congress listening.
🚀 The House passed this bill 397–28.
🚀 The Senate passed it 82–15.
This kind of bipartisan vote sends a clear message: science is still a national priority.
So what happens next? This bill helps stabilize NASA science and protect the future of discovery. But it’s important to note that the work isn’t done.
You don’t just flip a switch and recover from losing 4,000 people. NASA now has to rebuild teams, restart research, and repair trust across the workforce. But this vote gives science a path forward.
Thank you to everyone who spoke up, shared, wrote, and cared enough to act. That’s what made this possible.

a video taken by the eyewitness, Emily Heller, shows agents denying a self-identified physician access to the victim and telling bystanders to “just relax.”

At 0:55 a man identifies himself as a physician and tell ICE someone needs to “stop the bleeding.”
When he decides to intervene himself 40 seconds later, ICE pull their guns on him, threatening to shoot him too if he doesn’t “back the fuck up.”
🚨BREAKING — Content Warning: Disturbing
ICE/Border Patrol agents have shot a woman, who was a legal observer, in the face and killed her in a Minneapolis neighborhood. Details are still emerging, and the exact circumstances have not yet been officially confirmed.
According to video from the scene, a man heard gunshots and ran outside. The wife of the victim, who was in the car, is sitting on the ground nearby with a dog, visibly distressed. In the video, she is heard saying they had stopped to film, she yelled something, and moments later agents fired, fatally shooting the woman.
What happens next is even more alarming.
A man identifying himself as a physician attempts to approach the scene to provide medical assistance. He repeatedly tells agents that someone medically trained needs to intervene, that the victim is bleeding, and that a doctor is required to assess or pronounce death. Instead of allowing aid, agents point guns at him, threaten him, and force him to back away… leaving the woman shot inside the car without assistance.
Eventually, medics arrive and remove the woman from the vehicle.
This is an active, developing situation. More verified information is needed, but the video raises serious and urgent questions about use of force, denial of medical aid, and accountability.

Fire departments love to brag on their apparatus, like how this (100% custom-built!) ladder for their downtown station is 80,000 lbs.
A single passage of this truck exerts the same pavement damage as 37,000 passenger vehicles. Each time it rolls out for the ~98.5% of calls that aren’t fires, or it’s acting as basic medical response (~85% of calls) with 4 firefighters and 500 gallons of water - 37,000 passenger vehicles in damage, each way.
Every 100 calls is the equivalent cost for repair, resurfacing, etc as 3.7 million passenger vehicle trips, before adjusting expenses even higher for the wider streets fire departments demand and increased stormwater management this must be sized for on every street and parking lot, across a city.
The variety of ways in which failing to right-size apparatus and properly allocate equipment to actual need drives up costs in our cities is almost never-ending.
If you believe in smart fiscal governance, you are pro fire truck reform.
If you advocate for street safety, you’re pro fire truck reform.
If you want more urban housing variety, you’re pro fire truck reform.
If you’re a YIMBY or an urbanist, you’re pro fire truck reform.
If you’re pro transit, you’re pro fire truck reform.
If you want more sidewalks or bicycle networks, you’re pro fire truck reform.
The tent is almost as big as the trucks.

On this day in 1972, NASA astronauts Eugene Cernan and Harrison Schmitt lifted off from the surface of the Moon onboard Apollo lunar module Challenger's ascent stage, docking to Apollo command and service module America, piloted by Ronald Evans, approximately two hours later.
No humans have visited the Moon since then, 52 years ago. The Apollo 17 Command Module is on display at Space Center Houston.
The video was taken using a camera on the Lunar Roving Vehicle (LRV), and was remotely controlled from Earth.
