Cosmos 1 was a project by Cosmos Studios and The Planetary Society to test a solar sail in space. As part of the project, an uncrewed solar-sail spacecraft named Cosmos 1 was launched into space at 19:46:09 UTC (15:46:09 EDT) on 21 June 2005 from the submarine Borisoglebsk in the Barents Sea.

Aug 11, 2004 · Cosmos 1's mission goal is to perform the first controlled solar sail flight. Solar sailing is the only known technology that may someday enable interstellar flight. Most spacecraft are launched from land, but Cosmos 1 will launch on a Volna rocket from a Russian submarine beneath the Barents Sea.

Mar 18, 2025 · Physical AI systems need to perceive, understand, and perform complex actions in the physical world. In this paper, we present the Cosmos-Reason1 models that can understand the physical world and generate appropriate embodied decisions (e.g., next step action) in natural language through long chain-of-thought reasoning processes. We begin by defining key capabilities for Physical AI reasoning ...
