While the winds of Martian spring blew through Meridiani Planum in September, Opportunity reformatted its Flash memory then continued exploring Wdowiak Ridge on the western rim of Endeavour Crater. Even though the Flash-related issues soon returned, the robot field geologist hardly seemed to notice as it sent home two spectacular panoramas, presented the scientists with a rocky Martian mystery, and delivered yet another September to remember for the mission. And that's not all.

ESA announced today that Philae will be landing on November 12, 2014. What time the landing occurs depends on which landing site they use. If they go to the prime landing site,

On Sepember 22 at 02:24 UTC, Earth received word that MAVEN had ended its orbit insertion burn on time, completing its journey to Mars. Today MAVEN has released some of its very first data, taken by the Imaging Ultraviolet Spectrograph just eight hours after arrival.

Here are a few links to what will hopefully be working video feeds watching India's first-ever attempt to place a spacecraft into orbit around another planet. Begin watching in just a few hours, at 6:15 IST / 00:45 UT / 17:45 PDT for an orbit insertion burn scheduled to begin at 07:30 IST / 04:00 UT / 19:00 PDT!

There was celebration in the Mars mission control room in Bangalore on Monday following the success of the crucial four-second test firing of the Mars Orbiter Mission’s (MOM) 440-Newton liquid apogee motor. MOM will now go ahead with the nominal plan for the Mars orbit insertion on September 24 at 07:30 IST (02:00 UT / September 23 19:00 PDT).

Today's the day that MAVEN enters orbit at Mars, bringing the number of Mars orbiters up to four. So far everything looks good. The orbit insertion burn should begin tonight at 18:50 PDT / 01:50 UTC. I'll be on stage with Mat Kaplan and Rich Zurek at Planetary Radio Live, keeping up to date with the latest news from the spacecraft; here is a timeline in PDT, UTC, CEST, and IST to help you follow along.

ESA Mars Express Team

The Mars Express Flight Control Team at ESOC have been actively preparing for the flyby of comet C/2013 A1/Siding Spring on October 19. Initial estimates gave the possibility that Mars Express might be hit by 2 or 3 high-speed particles. Happily, additional observations by ground and space telescopes have shown the risk to be much lower – and perhaps even as low as zero. In today's blog post, the team explain how this (happy!) real-life, real-time development is affecting their preparations for fly-by.

Mars Orbiter Mission's fated arrival day is approaching fast! Here is the timeline of orbit insertion events, converted from India Standard Time to Universal, European, and Pacific time zones, and corrected for the 12.5 minutes it will take signals to reach Earth from Mars.

The countdown for the crucial and nerve-wracking Mars orbit insertion of India's Mars Orbiter Mission (MOM) on September 24 has kicked off. At ISRO's telemetry, tracking and command network (ISTRAC) in Bangalore, the mood among the scientists is right now a mixture of optimism, excitement, and nervous apprehension.

This morning, the European Space Agency announced the selection of a landing site for little Philae on the head of comet Churyumov-Gerasimenko. Although a primary site has been selected, landing Philae successfully is going to be tough, and the mission is now working to manage people's expectations.

A lot has happened behind the scenes on the Curiosity mission in the last few weeks. The mission received a pretty negative review from a panel convened to assess the relative quality of seven different proposed extended planetary science missions. Then, just a week later, the mission announced big news: they have arrived at Mount Sharp.

Comet Siding Spring is going to make a very close approach to Mars in October. Any comet dust that reaches Mars has the potential to inflict significant damage on the spacecraft orbiting the planet. As it turns out, however, Mars and its orbiters are likely to see very few, if any, impacts. Why?

According to a report in the Times of India, ISRO is deciding today whether to test-fire Mars Orbiter Mission's main engine to make sure it will work for their all-important orbit insertion maneuver on September 24. Both ISRO's Mars Orbiter Mission and NASA's MAVEN are in good health and on track for their arrivals in three weeks.
