Simplify's Take

What believers are saying

  • NASA extended TEST3 on April 24, 2026, preserving Sierra Lobo's White Sands presence.
  • SpaceDOC III at Glenn began February 27, 2024, with up to $282.1 million.
  • Revelio counts 532 employees in March 2026, up 16.5% since 2023.

What critics are saying

  • The April 24, 2026 TEST3 extension is sole-source and contestable by February 7.
  • Sierra Lobo still depends heavily on NASA contracts, especially Glenn and White Sands.
  • Losing NASA Glenn and White Sands primes would threaten Sierra Lobo's survival.

What makes Sierra Lobo unique

  • Sierra Lobo specializes in NASA and AFRL test-facility operations, not generic engineering.
  • It holds prime roles at Glenn, White Sands, Stennis, and Edwards simultaneously.
  • Its staff embeds inside government labs, making switching costs high.

Eco-Friendly And Efficient: How Thermoacoustic Stirling Engines Are Changing The Aerospace Game

Thermoacoustic Stirling Engines (TASE) might sound like a lot to digest in one go. But, in principle, they are acoustic equivalents of Stirling engines. Therefore, before delving deeper into TASEs, we must start with Stirling Engines.What is a Stirling Engine?The name comes from its inventor, Reverend Robert Stirling, who came up with an external heat engine vastly different from the traditional internal combustion engines used in cars. It is different in its use of the stirring cycle, which has three core features.Gasses used inside a Stirling engine never leave the engine. Unlike gasoline or diesel engines , these engines do not have exhaust valves to vent high-pressure gasses. It does not have explosions taking place, either
