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 $4m$. With the support of their governments in the US, Europe, and Canada, 20,000 people realized that vision as the $6.5m$ 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

Eisenhower's disarmament dilemma: from chance for peace to open skies proposal

President Eisenhower's image as a promoter of ‘peace and nuclear disarmament’ was established through speeches he made such as ‘Atoms for Peace’ (December 1953) and ‘Open Skies’ proposal (July 1955). However, Eisenhower's approach to the subject cannot be grasped without an understanding of his attitude towards the relationship between arms, war and disarmament. As he saw it, not only would the mere existence of nuclear weapons not trigger a war, they were actually the best guarantee against the eruption of a global conflagration. The real threat to world security was the repressive, closed, totalitarian and expansionist Soviet regime. War could be prevented only by a dramatic change in the competing ‐ and threatening ‐ ideology and social structure embedded in the Soviet system. Until then, the existence of nuclear weapons would ensure the free world's safety
