50 Years Ago: TIROS keeps hunting Hurricanes

TIROS Satellite

When someone asks you why we should spend money on the space program, start by telling them about TIROS. Fifty years ago, as our nation watched television breathlessly for the next manned space launches, the benefits of being able to launch satellites was paying off large dividends. On June 19 NASA launched the TIROS 5 satellite into orbit. The pictures coming from TIROS 4 had been degrading since the middle of June, and only some of its visual data was useful for forecasting. TIROS 5 was expected to relieve the aging TIROS 4 and start helping the nation prepare for the current hurricane season.

On June 15, 1962, The US Weather Bureau informed the news agencies that they believed the formation of the first hurricane of the 1962 season would be detected by "one or all of its battery of ships, planes, radar and TIROS weather satellites." In 1961, TIROS 3 had spied hurricane Esther in the Atlantic Ocean just as it was forming. The total 1961 count of watching storms from space had been 5 hurricanes and 1 tropical storm in the Atlantic, and 11 hurricanes and typhoons plus 1 tropical storm in the Pacific. By tracking these storms from space better than storms had ever been tracked before, many lives were saved, property prepared for the storms, and ships at sea diverted.

TIROS 5 was sent into space on the Thor-Able rocket from pad LC-17A just as TIROS 4 began experiencing failures. Unfortunately the launch placed the satellite into an elliptical orbit instead of a circular one; nevertheless the pictures from TIROS 5 were excellent at first. TIROS 5 would continue to work for 161 days.

When you consider all the hurricanes and ocean storms that have occurred over the last 50 years, that were tracked and watched from these remote stations in outer space, you begin to realize just how much damage and loss of life could have hit our nation without them. Think also of all the weather forecasting that has increased crop production as well as saved them and you begin to see the enormity of what the space weather satellites have achieved.
