    The James Webb Space Telescope Mission

    Twenty-six years ago a small committee report, building on earlier studies, expounded a compelling and poetic vision for the future of astronomy, calling for an infrared-optimized space telescope with an aperture of at least 4m4m. With the support of their governments in the US, Europe, and Canada, 20,000 people realized that vision as the 6.5m6.5m James Webb Space Telescope. A generation of astronomers will celebrate their accomplishments for the life of the mission, potentially as long as 20 years, and beyond. This report and the scientific discoveries that follow are extended thank-you notes to the 20,000 team members. The telescope is working perfectly, with much better image quality than expected. In this and accompanying papers, we give a brief history, describe the observatory, outline its objectives and current observing program, and discuss the inventions and people who made it possible. We cite detailed reports on the design and the measured performance on orbit.Comment: Accepted by PASP for the special issue on The James Webb Space Telescope Overview, 29 pages, 4 figure

    Costs of Producing Potatoes: 1980 and 1981 with Projections for 1982

    Costs of production for fresh potatoes will increase only slightly for 1982; substantially reduced seed costs should offset other operating cost increases. Processing potato costs should range from almost unchanged in the Red River Valley to a 4.2-percent increase in western Idaho. Central Wisconsin showed the lowest total cost for producing fresh potatoes, while Maine had a cost advantage over other producing areas for supplying fresh potatoes to northeastern U.S. markets. Eastern Idaho showed the highest cost per hundredweight for fresh potatoes. Washington's Columbia River Basin had the lowest cost for growing, harvesting, and storing processing potatoes, while the Minnesota/North Dakota Red River Valley had the highest. This study estimates costs for producing, storing, and packing potatoes in major U.S. production regions during 1980 and 1981 with projections for 1982
