"Northrop Grumman Secures $2.03 Billion Contract for 138 Satellites from SDA and Pentagon"

The Space Development Agency (SDA) has awarded Northrop Grumman a $732 million contract for 38 communications satellites as part of the U.S. military's low Earth orbit space architecture. These satellites will be part of the Transport Layer Tranche 2 Alpha, which aims to create a tactical network for transmitting classified data. The contract includes ground systems, five years of operations and sustainment, and an incentive payment for on-time delivery. The Alpha satellites are expected to launch in late 2026. Northrop Grumman has now won orders for a total of 132 satellites for the Transport and Tracking Layers of the SDA's network.

Lockheed Martin and Northrop Grumman secure $1.5 billion contract for satellite development

The Pentagon's Space Development Agency (SDA) has awarded contracts worth $1.5 billion to Lockheed Martin and Northrop Grumman for the development of prototype communications satellites. The 72 satellites will be part of the Tranche 2 Transport Layer constellation, aimed at providing encrypted communications for the U.S. military. The satellites are scheduled to launch by September 2026. The SDA's network also aims to provide missile warning and tracking capabilities, contributing to the Department of Defense's Joint All-Domain Command and Control project.

Europe bids farewell to Ariane 5, its trusted workhorse rocket

Europe's Ariane 5 rocket, the European Space Agency's "workhorse" rocket, successfully launched for the final time, carrying Germany's Heinrich Hertz (H2Sat) and France's Syracuse 4b military communications satellites into geostationary orbit. The launch marks the end of a 27-year era for Ariane 5, which played a crucial role in establishing Europe's presence in the communications satellite market. The rocket's final mission was delayed twice due to technical issues and bad weather.

Final Ariane 5 launch delayed due to technical issue.

Arianespace has postponed the final launch of the Ariane 5 rocket due to a potential problem with pyrotechnical systems. The company discovered a "nonconformance" in pyrotechnical transmission lines during acceptance testing for another program. The launch was carrying two government communications satellites and was scheduled for June 16 from Kourou, French Guiana. Arianespace has not set a new launch date for the mission, which marks the retirement of the Ariane 5.

SpaceX experiences mixed results with back-to-back launches and lightning strike.

SpaceX successfully launched a Falcon 9 rocket carrying two commercial communications satellites from Cape Canaveral Space Force Station, while a Falcon Heavy rocket launch from Kennedy Space Center was scrubbed due to an abort during the countdown. The Falcon Heavy rocket will attempt another launch on Saturday, April 29, to deploy communications satellites for ViaSat and Astranis.

"Uncertain weather threatens SpaceX Falcon Heavy launch"

SpaceX is set to launch a Falcon Heavy rocket from Kennedy Space Center's Pad 39A on Thursday, April 27, carrying ViaSat-3 Americas and Arcturus communications satellites. The launch window extends just over an hour to 8:31 p.m. EDT, with a 60% chance of favorable weather. The Falcon Heavy will fly on an east trajectory, and SpaceX will not attempt to retrieve boosters due to the weight of the satellites and trajectory. This will mark the first time Falcon Heavy flies with the deliberate goal of expending all boosters.
