WHERE IS JUNO?

As of September 8, 2014, Juno is approximately 416 million miles (670 million kilometers) from Earth. The one-way radio signal travel time between Earth and Juno is currently about 37 minutes. Juno is traveling at a velocity of approximately 33,400 miles per hour (15 kilometers per second) relative to the sun, and 83,400 thousand miles per hour (37 kilometers per second) relative to Earth. Juno has now travelled 1.42 billion miles (2.3 billion kilometers, or 15.28 AU) since launch. The Juno spacecraft remains in excellent health and is operating nominally.

DID YOU KNOW?

Did you know that Juno’s most sensitive electronics are housed inside of a vault that reduces their radiation exposure by a factor of 800?

The space around Jupiter is filled with energetic subatomic particles spinning around the planet at high speed, creating a lethal, radiation-filled environment. In order to keep the spacecraft functioning as long as possible in this intense environment, Juno carries a radiation-shielding vault that encloses Juno’s most sensitive electronics. This 500-pound (200-kilogram) titanium box the size of an SUV’s trunk is the first of its kind for a NASA planetary mission. What we learn from its performance will be useful not only in the design of other robotic explorers, but also in the development of shielding to protect future astronauts as they venture into the radiation-filled space outside Earth’s protective magnetic field.
