A critical time for commercial launch providers, The Space Review
"For a time last week, it looked like we would be in the midst of an unusually concentrated period of critical launches. In the span of less than a week, four launches of new, nearly new, or returning to flight vehicles were on global launch manifests: the inaugural launch of Japan's Epsilon small launch vehicle, the first launch of SpaceX's upgraded Falcon 9 v1.1, the second launch of Orbital Sciences Corporations Antares rocket carrying the first Cygnus cargo spacecraft, and the first Proton launch since a dramatic launch failure in early July.
Launch manifests are subject to change, of course, and that's what happened. While the Epsilon launch went off on schedule, and successfully, on Saturday, Orbital slipped its Antares launch a day, from this Tuesday to Wednesday, while the Falcon and Proton launches have been delayed until at least late this month. Nonetheless, all three upcoming launches remain critical in separate, but often interrelated, ways."
