Will NASA's Space Launch System be ready to launch a Europa mission in 2022?
Explore spinnable Saturn and Jupiter moons with Google Maps
Google Maps released several new map products that allow you to see the locations of named features on many solar system planets and non-planets, spinning them around in space with your mouse.
Voyager 40th anniversary: Revisiting the Voyagers' planetary views
Björn Jónsson argues that even now, 40 years after Voyager 1 and 2 were launched, a lot of the data they returned is still of high interest.
Voyager 40th Anniversary: Watching an Alien World Turn
In 1979, both Voyager missions captured thousands of photos of Jupiter as frames of movies of the giant planet spinning among its moons. In honor of the mission's 40th launch anniversary, Ian Regan has reprocessed the data to produce stunning new movies.
Voyager 40th anniversary: The transformation of the solar system
The Voyager missions transformed most of the large worlds of the solar system from points of light into places to be explored.
Congress gives NASA's planetary science division some love (and a Mars orbiter)
The House of Representatives proposed $2.1 billion for NASA's planetary science budget, which would be an all-time high. Part of the increase would be used to start work on a new reconnaissance and communications orbiter.
Jupiter from New Horizons
Using new image processing techniques, Alex Parker brings new life to an old image of Jupiter captured by the New Horizons mission on its way to Pluto over a decade ago.
A journey to Jupiter: Amateur astronomers create 1,000-image video of planet in motion
Peter Rosén shares an amazing animation of Jupiter made from more than 1,000 images taken by 91 amateurs from around the world.
Juno just flew past Jupiter for the fifth time. What have we learned from the mission so far?
There's no verdict quite yet on the giant planet's core, and scientists are still gathering clues about the accuracy of our current solar system formation models.
New treasures from Juno: Jupiter dazzles during fourth close approach
Image processor Björn Jónsson shares some of his latest stunning images of Jupiter, created using data from NASA's Juno spacecraft.
NASA's audacious Europa missions are getting closer to reality
Today, NASA announced progress on a spacecraft that would assess whether Jupiter's Moon Europa is habitable, and earlier this month, an agency-sponsored science team released a report on a separate lander mission that would directly search for signs of life.
Planetary discovery over the past quarter century
2016 marks the 25th anniversary of the creation of what has become one of the primary venues for the publication of research in planetary science: the Journal of Geophysical Research: Planets. This occasion is a good opportunity to look back at what we have learned in this era of expanded exploration and to try to take a peek at the future.
Great whirling Jupiter
Damian Peach's marvelous Jupiter photography, endlessly rotating in GIF form.
Juno to delay planned burn
The Juno mission posted a status report late Friday afternoon, indicating that they will not perform the originally planned period reduction maneuver during their next perijove (closest approach to Jupiter) on October 19. The delay changes the start date of the science mission and also all the future dates of Juno's perijoves.
New Findings are Conclusive: Europa is crying out for exploration
New scientific findings add to the evidence that Europa is spouting its liquid ocean into space. NASA has a mission to Europa in the works, but it wouldn't launch for at least a decade. Congress can make it faster, but it all depends on whether they can pass a budget this year.
Juno and Marble Movie update at Apojove 1
Juno is on its second of two long orbits around Jupiter, reaching apojove (its farthest distance from the planet) today.
A deep dive into the highest-resolution Voyager Jupiter data
A few weeks before the first Juno high resolution imaging, I decided to take a look at Voyager color images at various resolutions, with particular attention to high-resolution mosaics.
Juno's instruments return riches from first perijove
On August 27, Juno soared across Jupiter's cloud tops from pole to pole, with all instruments operating. NASA posted some terrific first results from several of the instruments today. And the JunoCam team released all 28 raw images taken during the close encounter.
Will Juno’s Instruments Observe the Moons of Jupiter?
It is not easy to observe Jupiter’s moons as more than points of light with Juno, because Juno will never get very close to any of the moons, but as its orbit shifts there will be opportunities to collect data on some of the moons.
Juno's first Jupiter close approach successful; best JunoCam images yet to come
NASA announced this afternoon that Juno passed through its first perijove since entering orbit successfully, with science instruments operating all the way. This is a huge relief, given all the unknowns about the effects of Jupiter's nasty radiation environment on its brand-new orbiter.
