Special Events


Delta College Planetarium astronomers will say “Hi” to NASA's Juno spacecraft on Wednesday, October 9, at 2:00pm.  The public is invited to attend the event.

NASA's Juno spacecraft will fly past Earth on October 9 to receive a gravity assist from our planet, putting it on course for Jupiter. 

The Juno mission team has invited amateur radio operators around the world to say "HI" to Juno in a coordinated Morse Code message. Juno's radio & plasma wave experiment, called Waves, should be able to detect the message. 

Delta College Planetarium astronomers will be transmitting their signal on a frequency of 28.270 MHz.

The Juno spacecraft will be within a distance of 50,000 kilometers from 2:00pm to 4:40pm EDT, and the Juno science instrument team has determined that Juno has the best chance of detecting the "HI" signal at this range. 

If the activity is successful, the Juno Waves instrument data containing the message will be shared by the Juno team and the Delta College Planetarium after the flyby.

Juno was launched in August, 2011 and will arrive at Jupiter in July, 2016.  Juno's principal goal is to understand the origin and evolution of Jupiter
