Tag Archive: Juno space probe orbit


This month the NASA space probe Juno completed its tenth science orbit around the planet Jupiter.  The spacecraft came as close as 2,100 miles from the planet’s clouded surface, and sent back to Earth what must be the most beautiful images of any celestial orb ever captured.  Just take a look at these images above and below and see if you agree.  The most astounding are the images from the southern hemisphere of the planet (as shown above), providing a new vantage of our view of the planet.

Juno collects scientific data and records it until Jupiter is free of “solar conjunction” and can safely transmit the data back to the science team on Earth.  Juno was launched August 5, 2011, and arrived at Jupiter on July 4, 2016.  Its “JunoCam” camera has produced some of the best images of any scientific instrument to date.  During these flybys, the spacecraft is probing beneath the obscuring cloud cover of Jupiter and studying its auroras, seeking to learn more about the planet’s origins, structure, atmosphere, and magnetosphere.  When Juno arrived at Jupiter, it moved faster than any human-made object has ever gone: 165,000 miles per hour.  This month’s photographs were taken at about 130,000 miles per hour.

The clarity is phenomenal and the imagery nothing but spectacular.  With the exception of the Sun, Jupiter is the most dominant object in the solar system.  Because of its size and the fact that it was the first of the gas-giant planets to form, it has profoundly influenced the formation and evolution of all the other planets.  In studying Jupiter, NASA hopes to learn more about the origin of the universe.  The cloud features, which appear like something from Vincent Van Gogh’s Starry Night, primarily consist of hydrogen and helium.

Our borg.com Best of 2016 list continues today with the Best in Print and a bonus wrap-up of other year’s bests.  If you missed it, check out our review of the Top Picks and Best Movies of 2016 here, the Kick-Ass Heroines of 2016 here, and the Best in Television here.

Without further ado, this year’s Best in Print:

Best Comic Book Series – Old Man Logan (Marvel).  With just enough backstory from prior series focused on the future world version of Logan/Wolverine, writer Jeff Lemire and artist Andrea Sorrentino took us through the struggle of the superhero that survived all his contemporaries, only to be plunged into a parallel world where everything is familiar but nothing is the same.

Best Graphic NovelWonder Woman: The True Amazon, Jill Thompson (DC Comics).  Writer/artist Jill Thompson is probably the best creator in comics today.  Her origin story of Wonder Woman is vibrant, and she presents a flawed, complex, and ultimately strong and fearless heroine.  The best Wonder Woman book we’ve ever read.

Batman TMNT 1 Williams

Best Comic Book Limited Series/Best Crossover Comic Book Series – Batman/Teenage Mutant Ninja Turtles (DC Comics/IDW).  James Tynion IV and Freddie Williams II pulled together an impossible team-up of characters that ended up working great together.  An action-packed, nostalgic fun trip.

DeptH cover 1

Best Comic Book Writing – Matt Kindt, Dept.H (Dark Horse).  Kindt pulls together an incredibly nostalgic assemblage of the best action concepts: classic science fiction of the H.G. Wells variety, G.I. Joe Adventure Team-inspired characters, and a fun character study and whodunit that will have you searching out your old game of Sub Search.  We just hope he makes a prequel at some point so we get to see a similar quest with an old fashioned copper-helmeted deep sea diver.  A fun read month after month and the best writing comics have to offer.

After the cut we continue with the best in comics, books, and more from 2016:

Independence Day wasn’t only linked to outer space in theaters this weekend with the release of Independence Day: Resurgence.  A real-life five-year mission ended this week with a new look at an old celestial friend.  Following U.S. missions that sent the Pioneer 10 spacecraft past Jupiter in 1973, and Galileo into its orbit between 1995 and 2003, NASA maneuvered a spacecraft named Juno into Jupiter’s orbit Monday, July 4, 2016, providing new, never before seen views of the solar system’s largest planet.  “Independence Day always is something to celebrate, but today we can add to America’s birthday another reason to cheer — Juno is at Jupiter,” said NASA administrator Charlie Bolden.

“And what is more American than a NASA mission going boldly where no spacecraft has gone before?  With Juno, we will investigate the unknowns of Jupiter’s massive radiation belts to delve deep into not only the planet’s interior, but into how Jupiter was born and how our entire solar system evolved,” said Bolden.

The burn of Juno’s 645-Newton Leros-1b main engine began at 10:18 p.m. Central Time, decreasing the spacecraft’s velocity by 1,212 miles per hour (542 meters per second) and allowing Juno to be captured in orbit around Jupiter.  Juno then turned so that the sun’s rays could once again reach the 18,698 individual solar cells that give Juno its energy.

“The spacecraft worked perfectly, which is always nice when you’re driving a vehicle with 1.7 billion miles on the odometer,” said Rick Nybakken, Juno project manager from the Jet Propulsion Laboratory.

Juno’s scientific purpose is to understand the origin and evolution of Jupiter.  Juno will investigate the existence of a solid planetary core, map Jupiter’s magnetic field, measure the amount of water and ammonia in the atmosphere, and observe the planet’s auroras.  The Juno spacecraft launched on Aug. 5, 2011 from Cape Canaveral Air Force Station in Florida.  Lockheed Martin Space Systems in Denver built the spacecraft.
