Spacecraft Juno arrives at Jupiter after FIVE YEAR flight
Spacecraft Juno is in the orbit of JupiterNASA launched spacecraft Juno into space about five years ago, and it just breached the orbit of Jupiter this week. You probably saw the auroras on Jupiter already, as a result of Juno getting closer.
The Atlantic - Scientists and space enthusiasts celebrated late Monday night as the spacecraft Juno successfully entered Jupiter?s orbit after five years and 1.7 billion miles of space travel.
?We just did the hardest thing NASA?s ever done,? Rick Nybakken, Juno?s project manager, could be heard telling his colleagues amid cheers in the moments after the spacecraft completed its task.
The successful maneuver, known as an orbital insertion, was executed via a series of pre-programmed commands that engineers transmitted hundreds of millions of miles to the outer solar system. The move, which represented the riskiest moment in the mission since Juno launched in August 2011, involved firing the spacecraft?s main engine so that the probe could slow down enough to leverage the planet?s gravity for a shift into its orbit.
How did Juno get there?
Juno was able to travel for five years thanks to solar panels and nuclear power. NASA equipped Juno with numerous mechanical data recording devices, including a camera. Maybe we'll see a selfie with an alien.? This is going to be very exciting to monitor.
If you forgot about how big space is, then consider this quote about Juno from the main source.
The Atlantic - at a speed of 165,000 miles per hour, it?s five times faster than New Horizons, seven times faster than Apollo 11, and 122 times faster than the Concorde. In January, Juno broke the record to become humanity?s most distant solar-powered envoy. ?Prior to Juno, eight spacecraft have navigated the cold, harsh under-lit realities of deep space as far out as Jupiter,? NASA wrote at the time.
You read correctly. Juno traveled 165,000 miles per hour while probably dodging space debris and meteors. Even going that fast, it still took five years to arrive at the orbit of Jupiter. It's not even on the planet, it's just in the area. That's how big space is, and that's not even a big example of space. There's places we won't ever reach in our lifetime, or maybe not ever. In addition, NASA turned Juno into the fastest man-made object in history.
Do you know anything faster than 165,000 mph?
