“Light” oxygen-16, with 8 protons and 8 neutrons, is the most common isotope found in nature, followed by much lesser amounts of “heavy” oxygen-18, with 8 protons and 10 neutrons.
The ratio (relative amount) of these two types of oxygen in water changes with the climate.
As of 2016, NASA claims that there are nearly 2,000 other spinoffs in the fields of computer technology, environment and agriculture, health and medicine, public safety, transportation, recreation, and industrial productivity.
Contrary to common belief, NASA did not invent Tang, Velcro or Teflon.

MESSENGER has provided multiple lines of evidence that Mercury’s polar regions host water ice.
Particularly high potassium concentrations were observed by MESSENGER's Gamma-Ray Spectrometer at high northern latitudes, as illustrated in the abundance map on the left side of the animation.
Spinoff is a NASA publication featuring technology made available to the public.
Since 1976, NASA has featured an average of 50 technologies each year in the annual publication, and Spinoff maintains a searchable database of these technologies.
has connected NASA resources to private industry, referring to the commercial products as spinoffs.
Well-known products that NASA claims as spinoffs include memory foam (originally named temper foam), freeze-dried food, firefighting equipment, emergency "space blankets", Dust Busters, cochlear implants, LZR Racer swimsuits, and CMOS image sensors.
