Casting Shadows on the Moon

Story

Much of the Moon is blanketed by a thick layer of dust, built up from the rocky surface over billions of years by the impacts of small meteorites. Hidden beneath the dust is evidence of ancient geologic activity – great volcanic eruptions, tectonic shifts in the crust, and vast deposits of once-molten material hurled outward during the formation of the giant impact basins.

Keeping Watch on Venus

Story

Venus has almost the same diameter as the Earth and is the next closest planet to the Sun. The similarity ends with the weather report, however. The surface temperature is more than 465 o C (870o F) and atmospheric pressure is 90 times that of Earth. The surface is hidden from view by a dense blanket of clouds, so we must use radar systems to “see” the landscape below.

Blazing the Trail in Space

Story

Able and a squirrel monkey named Baker were the first American animals to enter space and return safely. On May 28, 1959 at Cape Canaveral, Able was placed in the nose cone of Jupiter AM-18 secured by a contour cradle made of fiberglass with sponge rubber lining specifically built for her body. Included in the cradle were multiple electrodes used to collect information on Able’s reaction to noise, acceleration, deceleration, vibration, rotation, and weightlessness. The cradle was then placed in a capsule with a life support system that included oxygen, moisture and CO2 absorbers, and electrical heating and cooling systems to keep the monkey alive. Baker was placed her in own separate capsule in the nose cone.

Germs in Space

Story

When Space X launched the Dragon Spacecraft on Friday, April 18, it was carrying nearly 5,000 pounds of supplies and payloads, including critical materials to support more than 150 science investigations planned for International Space Station (ISS) Expeditions 39 and 40.  Among these materials are some that weigh hardly anything at all—microbes—of which one type was collected right here at the National Air and Space Museum in Washington, DC.

An Out-of-This-World Program

Story

How do you bring together two orbiting astronauts and more than 12,000 students scattered around the U.S. and Canada?  It’s not rocket science, but it's close.  First you have to find some very dedicated partners with a common purpose, like the Smithsonian National Air and Space Museum, the National Aeronautics and Space Administration, the U.S. Department of Education, and the National Center for Earth and Space Science Education.  Second you have to ensure an audience; which isn’t very difficult because who wouldn’t jump at the chance to talk to astronauts while in space?  Third, and most challenging, you have to put together the technology capable of linking 24 sites scattered around North America and Hawaii with something moving at 28,163 kph (17,500 mph) 354 km (220 miles) above the Earth’s surface.
