  • Mars
  • InSight's objective is to place a stationary lander equipped with a seismometer and heat transfer probe on the surface of Mars to study the planet's early geological evolution. (wikipedia.org)
  • Since knowing how the settling of dust out of Mars's atmosphere would affect solar cell performance would be critical to subsequent solar-powered missions on Mars, the MAE was included aboard the Sojourner rover to measure the degradation in performance of a solar cell as dust settled. (wikipedia.org)
  • Measurements taken by the MAE at local noon for the first 24 days of Pathfinder's operation on Mars showed that atmospheric dust obscured the test solar cell at a rate of 0.28% per day. (wikipedia.org)

  • exposure
  • The complex composition of secondhand smoke (SHS) provides a range of constituents that can be measured in environmental samples (air, dust and on surfaces) and therefore used to assess non-smokers' exposure to tobacco smoke. (bmj.com)
  • samples
  • Since these grains are direct samples from the moons' icy surfaces, determination of their composition will help to define and constrain the geological activities on and below the moons' surface, the exchange processes with the deeper interior, and assess its internal ocean habitability potential.

  • As the mission progressed, atmospheric dust would settle on the glass cover plate, blocking increasingly more sunlight from striking the solar cell, causing it to produce less power. (wikipedia.org)
  • material
  • The authors conclude that surface active material on the cotton dust leached onto the lecithin films, affecting surface tension properties. (cdc.gov)
  • At the equator the stable layer of ice might lie under as much as 1 kilometer of material, but at higher latitudes the ice may be just a few centimeters below the surface. (wikipedia.org)

  • relative
  • We believe the change in the relative scale heights of the dust and stellar disks is likely associated with the increased stability of the ISM against vertical collapse and the thin nature of the stellar disks. (wisc.edu)
