Carl Sagan Presents Six Lectures on Earth, Mars & Our Solar System … For Kids (1977)

The Roy­al Insti­tu­tion Christ­mas Lec­tures for Chil­dren — it’s a tra­di­tion that began back in 1825 when the inven­tor Michael Fara­day orga­nized an annu­al lec­ture series for kids, hop­ing to instill in a younger gen­er­a­tion a love for sci­ence. Almost two cen­turies lat­er, the tra­di­tion con­tin­ues. Emi­nent fig­ures like Sir David Atten­bor­ough and Richard Dawkins (watch here) pre­sent­ed lec­tures to young­sters in 1973 and 1991 (respec­tive­ly). And the great astronomer Carl Sagan took his turn in 1977, offer­ing six lec­tures on our solar sys­tem. The first two talks offer a broad overview of the plan­e­tary sys­tem, set­ting the stage for three pre­sen­ta­tions (see below) ded­i­cat­ed to Mars, a top­ic that holds spe­cial inter­est this week. With NASA just hav­ing land­ed its rover Curios­i­ty on the sur­face of Mars, it’s par­tic­u­lar­ly inter­est­ing to watch Sagan talk about the knowl­edge gained from ear­ly NASA orbiters, par­tic­u­lar­ly the Mariner and Viking mis­sions. In a rather time­ly way, Sagan’s lec­tures put the Curios­i­ty mis­sion in a grander his­tor­i­cal con­text, a deep­er his­to­ry of space explo­ration.

Sagan’s talks assume no spe­cial­ized knowl­edge and run rough­ly 60 min­utes each. You can find more Christ­mas lec­tures on the RI web­site here.
