Think of law as software. State agency budgets and staff are hardware. We have been stripping the copper for the past forty years, making software updates questionably useful, without durable fixes to the hardware. For constitutional environmental rights to make a difference, state natural resource departments need to be adequately funded and staffed.

Along the western coast of Southern Thailand, a series of bright tan beaches lines the Andaman Sea. These sandy expanses fill the gaps between the myriad other features touching the sea, from limestone karst towers to mangroves to built-up areas.

Often we are the only indoor public space in our communities and provide the only accessible public bathroom. We provide broadband internet to people who can't access it otherwise, and assistance with the email addresses and online forms required to access public welfare programs. Extreme poverty, unaddressed mental illness, the opioid crisis?--?all of it walks through our doors and makes itself at home.

I've been learning over the last few months how to make better use of the cornucopia of remote sensing data, satellites flying overhead snapping our picture, Instagram writ large. It offers a helpful reframing of my thinking about how water is spread across the landscape of New Mexico's Middle Rio Grande Valley.

Capt. William Shepherd, USN (Ret.), graduated from the U.S. Naval Academy in 1971 and served with U.S. Navy Special Warfare units in the Pacific and European theaters. In 1984, he was selected as a NASA astronaut and flew on three space shuttle flights carrying satellites and scientific payloads to space. In 2000, Capt. Shepherd and two Russian cosmonauts launched from Kazakhstan on a Soyuz rocket, docked with the International Space Station, and started Expedition One's 141-day mission in orbit. Capt. Shepherd retired from the space program in 2001 and is currently on staff as a senior researcher at Stevens Institute in Hoboken, N.J., where he lectures on applied system engineering and project management.

The start of spring 2026 brought bouts of heavy rain to much of Michigan. Above-normal levels of precipitation in March and early April--exacerbated by snowmelt in the northern part of the state--saturated soils and caused damaging flooding along multiple rivers. A flood watch spanned the entirety of both the upper and lower peninsulas as rain continued to fall in mid-April.

In a remote part of northern Mauritania on the Adrar Plateau lies a desert landscape rich in human history. This region of northwestern Africa is sprinkled with Paleolithic stone tools, Neolithic cave paintings, and the remains of medieval towns once used by caravans crossing the Sahara Desert.

Early spring around Hudson Bay in northern Canada is largely indistinguishable from winter. Sea ice still clings to land, and the boggy lowlands remain frozen. In the dulled tones of the boreal landscape, however, snow helps accentuate the area's subtle topography. In late March 2026, an astronaut aboard the International Space Station captured this photo of frozen channels feeding Hannah Bay--a southern offshoot of James Bay, which is itself an extension of Hudson Bay.
