US launches missile-detecting satellites into orbit as concerns about Russia in space grow

The U.S. launched multiple satellites capable of detecting global missile launches into orbit on Thursday, less than a day after new concerns came to light regarding Russia's space-based weapons capability.

The launch, handled by billionaire Elon Musk's SpaceX, includes six satellites in total. Two belong to the U.S. Missile Defense Agency (MDA) and four others are with the Space Development Agency (SDA).

The MDA's pair of Hypersonic and Ballistic Tracking Space Sensor (HBTSS) satellites, coupled with the SDA's Tracking Layer satellites will "detect hypersonic, ballistic, and other advanced threats earlier than terrestrial radars," according to the Pentagon.

"This launch represents a pivotal time for MDA as we enter a new phase of missile warning, tracking and defense," said Lt. Gen. Heath Collins, director of MDA. "These HBTSS satellites are an essential step forward in our efforts to stay ahead of our adversaries."
