What NASA claimed for years it couldn’t do—use solar power as an energy source on a space probe going beyond the orbit of Mars—it plans to do on Friday.

That’s when NASA intends to launch a space probe it has named Juno to Jupiter. Juno is to make 33 passes of Jupiter while all along getting power from three solar panels.

“It is quite interesting that NASA is going to use solar to travel to Jupiter—they once claimed it was not possible,” comments Bruce Gagnon, coordinator of the Global Network Against Weapons & Nuclear Power in Space. “I think it just goes to show that they needlessly put people and the planet in grave danger during past plutonium launches. It surely shows that our claims they could use solar in deep space were not wrong as NASA claimed during the Galileo, Ulysses, and Cassini launches.”

Solar Arrays: length of each solar array 29.5 feet (9
meters) by 8.7 feet (2.65 meters). Total surface area of
solar arrays: more than 650-feet (60-meters) squared.
Total number of individual solar cells: 18,698. Total
power output (Earth distance from sun): approximately 14 kilowatts;
(Jupiter distance from sun): approximately 400 watts.
