Ranger 3: Facts, Discussion Forum, and Encyclopedia Article

Ranger 3: Facts, Discussion Forum, and Encyclopedia Article

Above link is for a 60's spacecraft program called Ranger. Ranger missions crashed into the moon while making live television transmissions toward the end. Idea being that even "standard definition" TV (I don't have frame rates and resolutions for this yet) was superior to the earth-based telescopic observations of the day.

Now, Ranger 3 carried a "hard lander" built of -- get this -- ordinary balsa wood.

I am going to have to check this out.

10m net

10m Fred's Memorial Net, Wed 8:pm 28.446 MHz USB K5JVS Jack

I saw this net listing on the OK Section ARRL website.

Anyone worked it ?

Propagation Alert

This from Radio Cuba's resident Ham Radio / SWL expert... 73 Scott

Special Sporadic E layer openings alert !!!

The Earth's transit right trough the debris left by Halley Comet will very likely enhance the possibilities of highly ionized clouds forming at altitudes between 90 and 150 kilometers during late May 5 , the whole day May 6 and part of May 7.
The "cometary dust origin theory of sporadic E clouds" , may see a great chance
of been confirmed, especially in the Northern Hemisphere, where the number of expected visual meteor sightings will be up to 30 an hour during the peak times on May 6, but , I must add that the chances of enhaced ionization at E layer altitudes are much higher than what can be expected from the optical observations, because small size meteors, are much more likely to create ionized patches that may combine blown by the high altitude ionospheric winds and turn into compact highly ionized clouds capable of returning back to Earth radio waves on frequencies as high as the 2 meters of 144 to 148 megaHertz amateur band.
