Did scientists detect a signature of life in Venus' clouds? Or will the bombshell finding be proven false?
A new issue of The Planetary Report brings you our pride in the success of LightSail 2 and our gratitude to our members for making it happen. Plus Venus science from Akatsuki and Venus Express, and the status of planetary defense.
Javier Peralta plumbs the depths of Venus’ atmosphere through the eyes of the Venus Express and Akatsuki orbiters.
There are two types of atmospheric waves that are critically important on Earth and other planets: gravity waves and planetary waves.
In a paper released in Geophysical Research Letters today, Eugene Shalygin and coauthors have announced the best evidence yet for current, active volcanism on Venus. The evidence comes from the Venus Monitoring Camera, which saw transient hot spots in four locations along a system of rifts near Venus' equator. They saw the hot spots in two distinct episodes in 2008 and 2009.
Daniel Scuka describes the impending demise of the Venus Express spacecraft.
Venus Express is still alive and talking to Earth, but may fall into Venus' atmosphere in January.
Venus Express is nearly out of fuel. Any day could be the last of its long mission to Venus.
The two spacecraft currently orbiting the two innermost planets are both flying low in their orbits in the final phases of their missions. MESSENGER just performed a rocket burn to raise its orbit slightly, while Venus Express did the opposite.
Venus Express, currently the only spacecraft orbiting our nearest planetary neighbor, will soon meet a fiery end in Venus' atmosphere. But its work isn't over yet. ESA will maneuver Venus Express to dip into the uppermost Venus atmosphere and study how the spacecraft responds to atmospheric pressure, giving ESA valuable experience in aerobraking.
She’s alive! She’s alive! Or is she? A little more than a week ago, at the Lunar and Planetary Science Conference 2014, evidence was presented that Venus was geologically active, not in the recent past, like 100,000 years ago, but right now.
Earth's polar vortex has been in the American news all week. But we're not the only planet that has one; basically every world that has an atmosphere has a polar vortex. Here are lots of pretty pictures and animations of polar vortices.
With the New Year upon us, what can we look forward to in 2014? For me, the main event of 2014 is that ESA's Rosetta mission finally -- finally! -- catches up to the comet it has been chasing for a decade. We will lose LADEE, gain two Mars orbiters, and launch Hayabusa2. The year begins with an amazing 24 spacecraft exploring or cruising toward various planetary destinations.
Humans face the consequences of our own knowledge about the cosmos in this latest episode recap and analysis of Carl Sagan's classic series.
What Venus Express' Visual Monitoring Camera images of Venus have taught us about the motions of Venus' atmosphere.
Dispatches from five different worlds--all sent by robotic spacecraft on the same day.
Welcome to the monthly roundup of our solar system's envoy of electronic explorers! All eyes are on Curiosity as it approaches Mars this weekend. Who will lend support at the Red Planet?
This month, Opportunity is roving again, while Curiosity approaches Mars; Cassini's finally seeing rings, and will fly by Mimas, Titan, and Tethys; GRAIL has completed its primary mission and is journeying toward the second; Dawn is climbing to the HAMO2 orbit; and a rare transit of Venus is coming up on June 5/6.
Just a quick note because I didn't want to let the weekend go by without telling people that Venus Express' star trackers are back online.
Two brief mission updates. First, the good news: NASA announced yesterday that the twin GRAIL spacecraft have begun the science phase of the mission, transmitting precisely timed signals to each other in order to map the Moon's gravity field. The bad news: according to ESA, since the recent solar storm passed Venus, both of Venus Express' star trackers are suddenly unable to detect stars.
