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.

MAVEN orbit insertion timeline

Emily Lakdawalla • September 21, 2014 • 3

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.

So Close and Yet So Far: Why isn't Siding Spring going to sandblast Mars?

Tony Farnham • September 09, 2014 • 5

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?

Mars Orbiter Mission to test-fire main engine before orbit insertion

Emily Lakdawalla • September 04, 2014 • 1

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.

Mars orbiters plan for their October encounter with comet Siding Spring

Emily Lakdawalla • August 13, 2014 • 2

Now that we have reasonable confidence that our Mars orbiters will be safe from the close passage of comet Siding Spring, we are free to be excited about the opportunity that the encounter represents. At a community workshop on August 11, representatives from Mars missions shared their plans for great comet science.

A Checkup on Future Mars Missions
