The Quest for Life on Venus

Did scientists detect a signature of life in Venus' clouds? Or will the bombshell finding be proven false?

Transient hot spots on Venus: Best evidence yet for active volcanism

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.

Venus Express science mission ends; aerobraking experiment beginning

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.

LPSC 2014: The Curious Case of Active Volcanism on Venus

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.

Polar vortices across the solar system

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.

What's up in planetary missions in 2014

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.

What's up in the Solar System in August 2012

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?

What's Up in the Solar System in June 2012

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.

Venus Express star trackers recovered

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.

Good news, bad news: GRAIL science underway, Venus Express suffers storm damage

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.
