SKYCAL (Sky Events Calendar) will help you keep track of the sky by calculating the local date and time of all these celestial happenings.

It displays them on a convenient calendar that you can print and hang on the wall.

There is always something interesting happening in the sky.

The Moon cycles through its phases and occasionally passes near a bright planet. And sometimes the Moon itself is eclipsed as it passes through Earth's shadow.

The first frame shows an Earth-based Arecibo radar image in red overlaid on a mosaic of MESSENGER’s Mercury Dual Imaging System images, enabling for the first time the identification of the host craters for all of the radar-bright deposits.

Oxygen comes in heavy and light varieties, or isotopes, which are useful for paleoclimate research.Like all elements, oxygen is made up of a nucleus of protons and neutrons, surrounded by a cloud of electrons.All oxygen atoms have 8 protons, but the nucleus might contain 8, 9, or 10 neutrons.NASA spinoff technologies are commercial products and services which have been developed with the help of NASA, through research and development contracts, such as Small Business Innovation Research (SBIR) or STTR awards, licensing of NASA patents, use of NASA facilities, technical assistance from NASA personnel, or data from NASA research.

Information on new NASA technology that may be useful to industry is available in periodical and website form in "NASA Tech Briefs", while successful examples of commercialization are reported annually in the NASA publication "Spinoffs". Heinlein helped bring awareness to the spinoffs when he was asked to appear before Congress after recovering from one of the earliest known vascular bypass operations to correct a blocked artery; in his testimony, reprinted in the book Expanded Universe, he claimed that four NASA spinoff technologies made the surgery possible, and it was a few from a long list of NASA spinoff technologies from space development.“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.
