PAGE TWELVE Flight Into Space ONTARIO TODAY 1) hen the first manned rockets go up into space, the unmanned rocket . will not become out-of-date. In fact, the demand for the unmanned rocket will at once increase. The building of space stations will require a whole fleet of unmanned rockets to be sent up into orbit, carrying prefabricated parts for assembly. A fleet of tanker-rockets will also be sent into orbit. These will supply fuel for the earth-return rockets to carry man back from the satellite to earth when necessary. A rocket on a round trip to the moon or the planets would need to be an enormous size to carry fuel for the trig both ways. Much ° smaller manned rockets can be used if tanker-rocRets are sent out by remote control to provide fuel for the homeward voyage. The illustra- tion at top right shows spacemen connecting a pipeline to the fuel valve of a remote-controlled tanker-rocket. Methods of refuelling air- craft in mid-air have been known and practised for many years now. The same operation will be no harder in space. In fact, Msence of gravity could make it easier. Tanker - rockets and _ long layovers will be necessary when Man takes trips to Mars. 4 CHILDREN DO HAVE WORMS Ever since Grandmother's day > parents have relied on 'Mother Graves' to give rellef from worms.

OT CY 4 CURL LURES Effective Use r Graves : Mother bro for ay A trip froftEarth to Mars will need hardly any more fuel than a trip to the Moon, even though it will be nearly 1500 times the mileage, The reason is that on both trips most of the distance is covered while "coasting" after the rocket has built up to the escape velocity of 25.000 miles an hour. But a trip to Mars needs careful calculations. When Earth passes Mars it is 35-63 million miles away (the distance varies because the orbits of the two planets are elliptical). When Earth and Mars are on opposite sides of the Sun they are sometimes as much as 248 million miles apart. Clearly the spaceship leaving its base satellite above Earth must set off for Mars at just the right moment. If it mises the planet, it will be at the mercy of the Sun's gravity-pull. Morover, though the dis- tance between the planets is 35-63 million miles "as the crow flies", the curved route the spaceship has to take on its transfer orbit will be about 370 million miles. The outward trip will take about 260 days. But it will be no use the Mars travellers trying to get back straight away. If they did, they would reach Earth's orbit again only to find the Earth had passed that space in space six months before. Instead they will have to wait 450 days on Mars, or on an artificial satellite over Mars, until the two planets are near enough together to make the homeward run possible. Confident Living By Dr. Norman Vincent Peale SAFE,-THRILLING ADVENTURES I spent an evening not too long ago with a successful young man of ninety, IN SCIENCE ! Open the door to science for them, with a safety-tested Gilbert Chemistry set that provides excite- ment and fun while it shapes young minds and helps to start careers. Each set a complete laboratory with generous supply of chemicals, equipment and apparatus.

LRA ERI YEAST OM, BC TLL, NDg hf RS Sebastian S. Kresge, who founded the S. S. Kresge chain of stores. He asked me my opinion of a certain political issue that had just hit the headlines. I hadn't yet read about it and so I re- plied, "Why, Im sorry Mr. Kresge, I don't know anything about it." "What's the matter with you?" he asked smilingly. "Don't you keep up with current events?" : : It was obvious that, even at ninety, Mr. Kresge was up-to-date and attuned to the issues of the day. He's alive. I asked him how he kept his zest for life and he told me simply that he gets it from "waiting on the Lord.' His reference was to the Bible passage, "They that wait upon the Lord shall renew their strength; they that mount up with wings as eagles; they shall run, and not be weary; and they shall walk and not faint." I thought about that when a man wrote to me recently and asked if I could recommend any beoks corresponding to the Horatio Alger books I recommended Conrad Hilton's book "Be My Guest." This is a kind of modern Horatio Alger story. Whenever any trouble came, his mother SATURDAY, DECEMBER 12 OF EARTH A ROCKET | REACHES MARS y POSITION | OF EARTH AS ROCK ET LEAVES MARS would say to him, "Connie, pray your way through it and never give up." At one point, when he was broke and hundreds of thousands of dollars in debt, his mother told him, "I've saved two thousand dollars I want to invest in your business." He advised her not to endanger her savings in this way. But she insisted. "Don't you ever give up," she told him. "I believe in you. Keep on praying." His father, who was equally hard- headed, added another important word of advice. "Work. Just keep on working; don't stop trying," was his advice. Waiting on the Lord. Praying. Working. Standing up to things. These are the prin- ciples of success--success 'in business and success in life. : 0 Have you instilled these prificiples of successful living in your own life? Have you discovered that when you wait upon the Lord, you can run and not grow weary; walk and not faint? Have you learned to count on the guidance that prayer can bring you? Have you learned how to keep on working until what you work for comes. to you? And, most important, have you learned to stand up to your problems and not be defeated by them? If you can do these things, you will have learned the principles of success.
