Corn Ranch, commonly referred to as Launch Site One (LSO), is a spaceport owned and operated by Blue Origin which is located approximately 30 miles north of the town of Van Horn, Texas, United States.

The 670-square-kilometer (165,000-acre) land was purchased by Jeff Bezos in 2004.

The company uses the spaceport for testing and launch services for its New Shepard rocket. The launch site has a sub-orbital launch pad and also has a number of rocket engine test stands. The engine test cells are at the site to support the hydrolox, methalox and storable propellant engines that are used. There are three test cells for testing the methalox BE-4 engine, two of which support full-thrust and full-duration burns, and one that supports short-duration, high-pressure preburner tests.

The companies first human spaceflight launched from Launch Site One (LS1) on July 20, 2021. The flight, dubbed NS-16, carried its founder Jeff Bezos, his brother Mark Bezos, test pilot and Mercury 13 member Wally Funk, and Dutchman Oliver Daemen on a suborbital flight aboard New Shepard 4.^[1]
