V BATTALION Wednesday, June 9, 1971 College Station, Texas Page 3 Computers not all bad If you are having trouble with a computer that keeps sending you your brother-in-law’s book club bills, we don’t blame you for being piqued. But we feel obliged to say a kind word about computers as they are used by the National Aeronautics and Space Adminis tration and their value to space exploration. Take the problem of calculat ing the trajectory necessary for the safe return of the Apollo 13 crew in April 1970. Using the IBM-360 computer in the Mission Control Center Real Time Computer Complex in Houston, 12 six-minute computer runs were made toward determin ing the proper return trajectory for Apollo 13. Nine of these were transferred to the Return-to-Earth Console for examination. From these, three were selected for retum- to-Earth candidates, and two ad ditional compter runs of two minutes each were made on these three before the final return-to- Earth trajectory was chosen. From the initial computer runs to the six two-minute x-uns on the final return-to-Earth candidates, a total of 84 minutes computer time was required to determine the initial return trajector for Apollo 13. Somebody (we don’t know whether he used a computer or not) figured out that those 84 minutes are the equivalent of 1,040,256 man-years of manual calculations. That’s how long it would have taken one man to calculate the correct trajectory for the burn of the Lunar Module Descent Propulsion System engine to place the Apollo 13 crew on a free re- tuni trajectory.

If all the people in the Mission Planning and Analysis Division at that time (220) had been as signed the task, it could have been manually computed in just under 4,730 years or by the year 6700. That’s a long time to wait to find the way home. So, just foi*ward that unpaid bill to your brother-in-law and don’t knock the computers too much. Houston firm donates device for training Seabek Products Inc. of Hous ton has donated a $2,000 teaching aid to the Engineering Extension Service’s Telephone Technicians Training Center here. Chief Instructor Art Blake said the cable pressurization model will be used in a training course de signed to explain recent innova tions in cable pressurization. C. B. Tinsley, a Seabek em ploye, designed the unit and in stalled it at the training center. The mobil unit, mounted on large plywood boards, can simulate nat ural telephone plant conditions. “Mr. Tinsley has designed and built a teaching aid that makes instruction to students many times easier,” Blake said. Seabek Products Inc. is a man ufacturer of cable pressurization equipment. THREE REPRESENTATIVES from the College of Engineering, Institute Technologico Y De Estudios, in Monterrey, N. L.

For information send 25 Active duty pay increased for state guard AUSTIN—Gov. Preston Smith has signed into law a bill raising the minimum pay a National Guardsman may receive while on state active duty. The law applies to only the first four low-ranking pay grades, according to Maj. Gen. Ross Ayers, Texas adjutant general. According to the bill, as author ed by Rep. John Traeger of Se- guin, the minimum pay is set at the per diem rate paid state em ployes for travel. This is now $14 a day, he indicated. The per diem rate increases to $16 daily effective in September Traeger said the law would pitch the level of pay so Guards men wouldn’t take too large a fi nancial beating while on state ac tive duty. State active duty in cludes aiding in civil disorders or natural disasters. AlXiEN OLDS. - CAD.
