Probing the Planets

Mars and Venus are the

planets nearest the earth.For many

centuries,men have been eager to learn more aboutthese close neighbors in our solar system.Since the

Space Age began,scientists have built new tools toincrease their knowledge of Mars and Venus.Themost improtant of these tools are unmanned space-craft called planetary probes.

American space scientists announced plans forthe Mariner series of planetary probes in 1961.Thelaunchings had to be made on certain days,deter-mined by the positions of the earth,the sun,and

Mars or Venus.Each probe would radio back toearth information collected by sensing instrumentsinside the spacecraft.

The first probe to return information about Venus

hundred and nine days later it passed within 22,000miles of Venus.Mariner 5 was launched on June 14,阅

1967.It passed within 2,500 miles of Venus.On读

October18,1967,the Russian planetary probe Venus高

4 planted an information -transmitting capsule on thesurface of Venus.

版

Information radioed from the probes indicatedthat the surface temperatures on Venus may be ashigh as 800F.The pressure of the atmosphere maybe between 20 and 100 times that of the earth.The

Venusian atmosphere is probably mostly carbondioxide,with little water or oxygen.

The first probe to return information about Marswas Mariner 4,launched on November 28,1964.

Eight months later it passed within 6,200 miles of

Mars and sent to earth twenty-one TV pictures of thesurface.The photos showed a dry surface coveredwith many craters.Other radioed information indi-cated a thin atmosphere and no magnetic field orradiation belt.More information was collected on July31,1969,when Mariner 6 flew within 2,130 miles of

Mars sending back photographs and radio signals.

Future planetary probes,even more carefullyplanned than the Mariner series,will help us livebetter in the universe of the future

Jupiter C be ready to boost a new satellite into orbit?版

About eight weeks later.on January 31,1958,a Jupiter C rocket successfully placed in earth orbitthe first United States artificial satellite,Explorer 1.

Packed with scientific instruments,Explorer 1 hadbeen hastily constructed and weighted only 30pounds.Yet Explorer 1 sent back to earth more im-portant information than had Sputnik 2,launchedabout the same time but thirty-six times heavier.

The most important information provided by Ex-plorer 1 indicated that a belt of intense radiationsurrounded the earth.Dr.James A.Van Allenstudied this information.He soon began mappingthe radiation belt that now bears his name.

The fiery accident on the launch pad had made

Explorer 1,rather than Vanguard,America's firstsatellite.Even more surprising,Explorer 1 discov-ered the Van Allen radiation belt.
