US rocket company Astra Space seeks to raise $250 million in comeback bid

Astra Space is seeking to raise $250 million at a $1 billion valuation in a funding round expected to close in Q3 2026, according to CEO Chris Kemp. The raise would support expansion of its mobile-launch Rocket 4 program (targeting launches from 2027) and satellite propulsion business after the company was taken private in 2024 at $11.25 million and raised $80 million the prior year for legal costs and refinancing.
