Boeing and Lockheed Martin have been awarded NASA Launch Services (NLS) contracts to place planetary, Earth-observing and science payloads into space over a 10-year period.

The indefinite delivery/indefinite quantity contracts could involve up to 70 launches with a potential value of $5 billion.

Boeing has been awarded three missions and five options, with a potential value of $417 million. At this stage it is not known which Delta models, the Delta II, III or IV, will be used for each launch.

The NLS includes a clause which allows emerging launch service providers to introduce qualified launch vehicles unavailable when contracts were signed.
