NSW ATMOSPHERIC PRESSURE MEASUREMENT ..BYÂ· SKYLARK ROCKET

Statement by the.Minister for Supply (Hon. Allen Fairhall)

The Minister for Supply (Mr. Allen Fairhall) said today

that the Skylark rocket fired to a height of 78 miles at Woomera

this morning had carried a new experiment. Â·

The experiment was a measurement by Phillips vacuum gauge

of the surrounding pressure in the atmosphere above 60 miles ~

the first time this method of measuring pressure had been used r

in Skylark. Ã¢ÂÂ

Other experiments - for the Sheffield University and the

University College,, London - including examination of the

properties of the D layer of the ionosphere (about 4-0 to 50

miles altitude);~

1Ã¢ÂÂ By observing the transmission and reflection of low

frequency radio waves by rocket-borne receivers;

2, Study of the distribution of atomic hydrogen in the

atmosphere and beyond;

3. Measurement of the density profile of positive ions

in the ionosphere,

Mr. Fairhail said that all experiments had been successfulÃ¢ÂÂ
