The launch of a Landsat environmental monitoring satellite Monday from California’s Central Coast will be the first liftoff of a United Launch Alliance Atlas 5 rocket since the company confirmed there will be 29 more Atlas 5 flights before the Atlas family’s retirement.

The Landsat 9 satellite is set for launch Sept. 27 from Vandenberg Space Force Base in California. These photos show the encapsulation of the environmental monitoring spacecraft inside the payload fairing of its Atlas 5 launcher.

The head of NASA’s space operations division said this week an unpiloted test flight of Boeing’s Starliner crew capsule to the International Space Station, delayed from August by valve problems, will likely not launch until next year.

The next Landsat observatory has been mounted on top of a United Launch Alliance Atlas 5 rocket in California for liftoff Sept. 27, continuing an unbroken record of Earth observations to track urban sprawl, water usage, tropical deforestation, retreating glaciers, and more over the last half-century.
