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.
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.
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.
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.
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.
India's Mars Orbiter Mission has accomplished its second trajectory correction manuever, a small rocket burn lasting only 16 seconds. Meanwhile, NASA's MAVEN is testing out its instruments, with one obtaining "first light" on Mars.
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.
Today I am delighted to welcome India into the ranks of interplanetary travelers: Mars Orbiter Mission has successfully propelled itself onto an interplanetary trajectory, departing Earth forever and setting sail for Mars. Congratulations to India, to the Indian Space Research Organisation, to the mission's scientists and engineers, and to the people of India.
Today is the day when India's Mars Orbiter Mission will fire its rocket to depart Earth and begin its 300-day journey to Mars. The rocket burn begins on December 1 at 00:49 IST (today at 19:19 UT / 11:19 PT).
Two spacecraft launched for Mars this month: Mars Orbiter Mission on November 5, and MAVEN on November 18. MAVEN is now on an interplanetary trajectory, while Mars Orbiter Mission is still in Earth orbit and will not depart for Mars until the end of the month. A lot of people are asking me: why the difference? Here's your answer, with input from Dave Doody.
Yesterday, the Mars Orbiter Mission was commanded to perform a rocket burn that would have raised the apogee of its orbit around Earth. The spacecraft began its burn, but underperformed. ISRO has planned a supplemental burn for November 12 at 05:00 IST (today at 15:30 PT / 23:30 UT) in order to make up the deficit.
The Mars Orbiter Mission completed its first, second, and third of six planned maneuvers in Earth orbit successfully last week. However, the fourth maneuver, conducted on Sunday at 12:36 PST / 20:36 UTC / Monday 02:06 IST, failed to lift the apogee of the orbit as high as planned.
When the Mars Orbiter Mission launched yesterday, it launched into Earth orbit. The Mars Orbiter Mission must perform several rocket burns in order to increase its orbital altitude before departing for Mars. The first burn was completed successfully just minutes ago.
The PSLV carrying ISRO's Mars Orbiter mission shot like a firework off the launch pad today, placing the spacecraft precisely into its planned elliptical orbit of Earth. Now the 10-month cruise phase begins. Congratulations to ISRO!
The excitement is really building toward India's first-ever attempt at an interplanetary spacecraft! Launch day is quickly approaching for the Mars Orbiter Mission. In this lengthy post, I provide answers to frequently asked questions about the mission and its goals.
