Original sentence: Advancement in solar cell technology and efficiency over the past several decades now makes it economically feasible to use solar panels of practical size to provide power 5 Astronomical Units (AUs, or roughly 460 million miles) from the Sun.Also, by using solar energy, NASA avoids the protests associated with launching RTGs into space (due to accusations of public safety risks, which NASA refutes in detailed scientific reports); however, it should be noted that NASA plans several more projects involving RTGs, and the decision to use alternate technology on this mission is more practical and economical than political.It will be the first mission to Jupiter using solar panels instead of the radioisotope thermoelectric generators (RTGs) used by Pioneer 10, Pioneer 11, the Voyager program, Cassini–Huygens, and the Galileo orbiter.The total area of the arrays is over 60 square meters.This is enough to produce over 18 kilowatts in Earth orbit, but will produce just over 400w at Jupiter
Edited sentence: Advancements made in both solar cell technology and efficiency over the past several decades makes it economically feasible to use solar panels of practical size to provide power 5 Astronomical units from the Sun.By using solar energy NASA avoids the criticisms associated with launching RTGs into space.In the past, NASA has been criticized for taking risks with public safety by using RTGs, which NASA refutes in detailed scientific reports.It should be noted that NASA plans several more projects involving RTGs, and the decision to use alternate technology on this mission is more practical and economical than political.Juno will be the first mission to Jupiter using solar panels instead of the radioisotope thermoelectric generators (RTGs) used by Pioneer 10, Pioneer 11, the Voyager program, Cassini–Huygens, and the Galileo orbiter.The total area of the arrays is over.This is enough to produce over 18 kilowatts while in Earth orbit, and just over 400 watts while on Jupiter orbit
