In my latest piece for The Planetary Report, I argue that we’ve largely lost the rhetorical ability to defend the unquantifiable values of space exploration—beauty, curiosity, discovery—in the face of an unrelenting focus on utilitarian pragmatism.

A cosmic perspective worth fighting for

NASA's science budget is under threat. Here's what that could mean to the human endeavor of exploration.

The Destruction of NASA Would Be a Blow to Our Collective Imagination

As NASA grapples with major proposed budget cuts and losing some of its most brilliant minds, America’s willingness to look outward is also at risk.

Trump’s NIH cuts are hitting cancer research hard. NCI scientists say grant funding has been slashed, lifesaving trials canceled, and top researchers pushed out. It's a crisis in the making, and lives are on the line.

Listen: Some Scientists Speak Out on Deep Cuts to National Cancer Institute, While Others Flee - KFF Health News

The U.S. has made enormous progress reducing cancer mortality since the 1990s, partly due to significant investment in research at the National Cancer Institute. But scientists say the Trump administration has been hollowing out the agency in its push to dramatically shrink the federal government.

Makenzie Lystrup's departure from the Goddard Space Flight Center coincided with the release of an open letter to NASA's interim administrator signed by hundreds of current and former agency employees.

Nearly 3,000 people are leaving NASA, and this director is one of them

Makenzie Lystrup’s departure from Goddard comes soon after the resignation of the director of JPL.

What’s really at stake if NASA’s science budget gets slashed and entire science missions are canceled?

We asked the scientists leading those missions, and their stories reveal what we all stand to lose.

I cannot articulate to you how damaging this will be to NASA science and to the scientific leadership of the United States generally.

To say nothing of the precedence of the White House and NASA leadership simply ignoring Congress.

White House works to ground NASA science missions before Congress can act

“We would be turning off some fabulous missions that are doing extremely well.”…

Just thinking of the Harvard computer women a century ago, who looked at images of the universe like this by eye to make discoveries. They revolutionized astronomy, and Rubin definitely will too!

Also, wow how excited would Henrietta Leavitt and Williamina Flemming be to see this! 🤩

‼️We're just TWO DAYS from Rubin's first images! #RubinFirstLook‼️ So let's talk images📷

NSF–DOE Rubin Observatory's LSST Camera — the largest digital camera ever built — produces 3200-megapixel images... 🔭🧪

But what does that mean, exactly? 🤨

📷: J. Orrell/SLAC Lab

A view looking into the LSST Camera's huge opening. The camera opening is a large black donut shape, with reflections of ceiling light revealing the presence of glass lenses. In the center of the opening is the camera's focal plane detector, which is made of 189 square CCD chips arranged in a roughly square shape. The camera is suspended on a white metal frame with white handrails. The completely white room gives the image an overall sterile feel.

The just-completed Vera C. Rubin Observatory is set to transform astronomy. Its wide and fast survey will discover billions of dynamic objects while building up a deep map of the universe.

Learn more in this week's issue of Science: scim.ag/4n6oiak

Unlike most telescopes, the just-completed Vera C. Rubin Observatory, atop Chile’s Cerro Pachón, takes the big picture. Equipped with an 8.4-meter main mirror and a 3200-megapixel camera, it will capture the entire visible sky every 3 days before starting again. Algorithms sensitive to anything that changes will find billions of previously unidentified objects, including Earth-threatening asteroids and exploding stars called supernovae.
