text: # Zenith Star
  
  Zenith Star was a Directed-energy weapon that started development as part of the US Strategic Defense Initiative.
  
  It included the Alpha laser, a high energy hydrogen fluoride chemical laser, and the LAMP mirror which was a 7 segment adaptive optics mirror.
  
  Zenith Star was never put in orbit, but the Alpha LAMP Integration (ALI) project carried out some ground-based $tests.^{:20}$
  
  ## Legacy
  
  Around 1998 Space-Based lasers were reconsidered and led to the Space Based Laser - Integrated Flight eXperiment (SBL-IFX) project 2000-2002.
