NASA shifts mission competitions toward science-first proposals

NASA's Competition Model 2.0 will defer detailed engineering, cost, and implementation work until it is needed, prioritizing the science case in initial proposals. For its accelerated two-step route, NASA says the changes will remove roughly half the initial proposal material and cut the interval from solicitation to step-two selection from 35 months to about 19.5 months. [5]

Why it matters

Preparing a mission proposal consumes researchers' time and resources before they know whether their idea will advance. NASA says a lighter initial submission should give investigators without major institutional backing fair consideration, while later implementation studies are intended to expose risks before final selection. [5]

Key insights

  • The initial submission will ask for a science case, a science implementation plan, and a proof-of-concept mission design—not the full engineering package required later. [5]
  • For the accelerated two-step route, implementation studies will involve NASA centers, with JHU/APL a possible participant for New Frontiers or Discovery depending on the selected science. [5]
  • The change is not universal: NASA says its largest missions will retain their previously reformed management approach, and the broader rollout will happen in stages. [5]

NASA runs Artemis engine test for full launch duration

NASA ran developmental RS-25 engine No. 10001 for 500 seconds, matching the firing duration during an SLS launch, and reached the 111% power level required of new production engines. The test targeted acceptance testing of future Artemis flight components and validation of a new nozzle thermal-protection system, although the developmental engine itself will not fly. [7]

Why it matters

The test exposes hardware to launch-relevant operating conditions before flight. Four RS-25 engines provide up to 2 million pounds of combined thrust on each SLS launch, making component acceptance and thermal protection directly relevant to the rocket's propulsion system. [7]

Key insights

  • Duration and power tested different requirements: 500 seconds matched launch firing time, while 111% matched the thrust level needed from new production engines. [7]
  • The new thermal-protection system is intended to shield the engine nozzle from the thermal environment around SLS during launch. [7]
  • NASA describes the run's objectives and operating conditions, but the supplied account does not provide detailed component acceptance results or thermal-performance measurements. [7]
