Simulation Expectation

Erkenntnis
AbstractI present a new argument that we are much more likely to be living in a computer simulation than in the ground-level of reality. (Similar arguments can be marshalled for the view that we are more likely to be Boltzmann brains than ordinary people, but I focus on the case of simulations.) I explain how this argument overcomes some objections to ...

Pitot survey of exhaust flow field of a 2-D scramjet nozzle at Mach 6 with air or freon and argon used for exhaust simulation [PDF]

A pitot-rake survey of the simulated exhaust of a half-span scramjet nozzle model was conducted in the Langley 20-Inch Mach 6 Tunnel to provide an additional data set for computational fluid dynamics (CFD) code comparisons. A wind-tunnel model was tested

Spirulina supported plant growth in regolith simulants and elevated levels of CO2

Frontiers in Space Technologies
IntroductionA key element for sustainable off-world habitation is the ability to grow food through in-situ resource utilization (ISRU). Growth substrates are required to overcome the challenges of ISRU in the space environment, including the use of ...

ISRU Soil Mechanics Vacuum Facility: Soil Bin Preparation and Simulant Strength Characterization [PDF]

, 2012
Testing in relevant environments is key to exploration mission hardware development. This is true on both the component level (in early development) and system level (in late development stages).

Surface Energy of Insoluble Organic Matter Simulant: Evaluation Based on Adhesive Force Measured by Centrifugal and Impact Separation Methods

The Planetary Science Journal
In protoplanetary disks, organic mantle is regarded as promoting the collisional sticking of rocky dust grains. However, the surface energy, which is one of the primary factors determining collisional sticking, has not been well quantified.

Patch Plate Materials Compatibility Assessment [PDF]

Lunar dust proved to be a greater problem during the Apollo missions than was originally anticipated. The highly angular, charged dust particles stuck to seals, radiators, and visors; clogged mechanisms; and abraded space suits.
