Cheyenne Bottoms is the largest inland wetland in the United States. Water normally diverts from rivers into the vast marshland. The wetland water level changes with precipitation and surface flows. For example, 2007 was a wet year. And 2013 was a dry year.

We wouldn't have seasons here on Earth if not for the planet's 23.5 degree axial tilt. Axial tilt is also known as obliquity. Earth's obliquity and its relationship with the sun give us two solstice points and two equinox points. As we orbit through each solstice and equinox, the amount and angle of daylight change.

While the best soccer players in the world show off their footwork skills, the best Earth observation satellite program in the world displays its skill at detecting change over time. Landsat images show the rapidly growing city of Doha in Qatar. It's the country's capital and the location of the 2022 men's World Cup.

Two decades of drought are contributing to low water levels in reservoirs along the Colorado River, including Lake Powell.
Lake Powell’s highest recorded water level was in 1983. In this 1984 Landsat 5 image, the lake’s elevation was 3,702 feet above sea level.

Lake Mead and the Mega Drought.
Image of the Week.
Drought over the past 20 years in the Colorado River Basin, and a growing demand for water, have brought Lake Mead to historically low levels.
In 1972, the year Landsat 1 captured its first images, Lake Mead’s elevation was 1,155 above sea level.

50 years of teamwork. 50 years of innovation. 50 years of resilience. In 1966, Secretary of the Interior Stewart Udall announced his vision to create a program aimed at gathering facts about the natural resources of the Earth from Earth orbiting satellites. It was a bold proclamation. It was also an idea that worked and continues to work 50 years on.

The Landsat program conceived of in the 1960s, has been running longer than any remote sensing program. The idea was simple: position a satellite in a nearly polar orbit fixed to the solar angle so that each daytime pass would cross the equator at roughly the same local time.
