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

Co-evolution of Firms, Industries and Networks in Space

Ter Wal A. L. J. and Boschma R. Co-evolution of firms, industries and networks in space, Regional Studies. The cluster literature suffers from a number of shortcomings: (1) it often neglects that cluster firms are heterogeneous in terms of capabilities; (2) it tends to overemphasize the importance of geographical proximity and underestimates the role of networks; and (3) it hardly addresses the origins and evolution of clusters. The authors propose a theoretical framework that brings together the literature on clusters, industrial dynamics, the evolutionary theory of the firm, and network theory. It is described how clusters co-evolve with: (1) the industry with to they adhere; (2) the capabilities of the firms they contain; and (3) the industry-wide knowledge network of which they are part.

La documentation sur les clusters souffre d'un nombre de points faibles: (1) elle ne tient compte du fait que les clusters d'entreprises sont heterogenes en termes de leurs capacites: (2) elle a tendance a souligner l'importance de la proximite geographique et a ne pas donner assez d'importance au role des reseaux; (3) elle aborde a peine les origines et l'evolution des clusters. On propose un cadre theorique qui reunit la documentation sur les clusters, la dynamique industrielle, la theorie evolutionniste des entreprises et le theorie des reseaux. On presente comment les clusters evoluent simultanement avec: (1) l'industrie a laquelle elles s'adherent; (2) les capacites des entreprises concernees; et (3) le reseau de connaissance a l'echelle industrielle dont elles font partie.

Koevolution von Firmen, Branchen und Netzwerken im Raum, Regional Studies. Die Literatur uber Cluster leidet unter einer Anzahl von Mangeln: (1) Es wird oft vernachlassigt, dass Cluster-Firmen hinsichtlich ihrer Fahigkeiten heterogen sind; (2) die Bedeutung der geografischen Nahe wird in der Regel zu stark betont, wahrend die Rolle von Netzwerken unterschatzt wird; und (3) auf den Ursprung und die Evolution von Clustern wird kaum eingegangen. Wir schlagen einen theoretischen Rahmen vor, in dem die Literatur uber Cluster mit der Literatur uber Branchendynamik, die evolutionare Theorie der Firma und die Netzwerktheorie zusammengebracht wird. Wir beschreiben, wie sich Cluster gemeinsam mit den folgenden Faktoren weiterentwickeln: (1) der Branche, der sie angehoren; (2) den Fahigkeiten der in ihnen enthaltenen Firmen; und (3) dem branchenweiten Wissensnetzwerk, dem sie angehoren.

La literatura de aglomeracion adolece de varias deficiencias: (1) ignora con frecuencia que las empresas de aglomeracion son heterogeneas en lo que afecta a las capacidades; (2) tiende a poner demasiado enfasis en la importancia de la proximidad geografica y subestima el papel de las redes; (3) apenas considera los origenes y la evolucion de las aglomeraciones. Nosotros proponemos una estructura teorica que agrupe la literatura sobre aglomeraciones, dinamicas industriales, la teoria evolucionaria de empresas y la teoria de redes. Describimos como se desarrollan las aglomeraciones con: (1) la industria a la que pertenecen; (2) las capacidades de las empresas contenidas en ellas; y (3) la red de conocimiento industrial de la que forman parte.
