Learning About Satellites on an Historic Day
Today marks the 50th anniversary of human space flight.
In honor of this historic day, Dr. Igor Geogdzhayev, NASA scientist and dad of Masha in 3rd grade, came in to teach the students about Earth Observing Satellites including his most recent project, GLORY.
Here are just a few of the new bits of information we learned from Igor:
- The A-Train doesn’t just take you from Inwood to the Rockaways, it’s also an orbital pathway in space. The Afternoon Constellation, also known as the A-Train, is a series of Earth-observing satellites flying in close formation. The A-Train orbits the Earth once every 100 minutes.
- Aerosols, or dust found in the atmosphere, can have an effect on global climate. The aerosols can range from salt from evaporated sea water to soot from volcanic eruptions or factory emissions. Aerosols can reflect or absorb sunlight in our atmosphere.
