Mars Orbiter Spacecraft Crosses Half Way Mark of its Journey 
 
Today (April 09, 2014) at 9:50 am IST, India's Mars Orbiter Spacecraft crossed the half-way mark of its journey to the Red Planet along the designated helio-centric trajectory.

 Mars Orbiter Spacecraft was launched onboard PSLV-C25 on November 05, 2013. On December 01, 2013, Trans Mars Injection manoeuvre was conducted successfully and the Spacecraft was set in its course towards Planet Mars through a helio-centric trajectory. Soon after the Spacecraft crossed the sphere of influence of Earth, a Trajectory Correction Manoeuvre (TCM) was performed successfully on December 11, 2013.

 ISRO has been continuously monitoring the Spacecraft using its Deep Space Network complemented by that of NASA-JPL. As the Spacecraft is on its designated trajectory, the TCM planned for April 2014 is not considered essential. If required, the next TCM is planned to be carried out in June 2014.

 Mars Orbiter Spacecraft and its five scientific instruments are in good health. Periodic tests are being done on the different levels of autonomy built into the Spacecraft for managing contingencies.

 At present, the radio distance between the Spacecraft and the Earth is 39 million km. A signal from the Earth to the Spacecraft and back to Earth takes 4 minutes and 15 seconds. Soon, the High Gain Antenna of the Spacecraft will be put in service for handling communications with the ground stations.

 The Mars Orbit Insertion (MOI) manoeuvre would be performed on September 24, 2014.

If everything goes as planned, MOM will get inserted into its Martian orbit, exactly 200 days from 7th March

Quote
Maintaining that the next challenge for the scientists would come on September 24, when the spacecraft will have to be energized  after a hibernation of 9 months, he said: “ The firing at that time will last for nearly 1500 seconds. The Mars Orbiter Insertion would be a major challenge for us but we have done a lot of ground simulation for that.”

Quote from: Same article
Mangalyaan will be inserted into the Mars orbit after 200 days after which it will carry out scientific experiments, says Indian Space Research Organisation (ISRO)

So, no cruise phase science?


There's also been only the one image of Earth so far..

I'd skimmed through that paper, but thought that the second image was a blown up inset from the first, transformed for a different perspective. Mea culpa.

EDIT:
Paper

But anyway, including that, there're only 2 images, and not even one of a full blue marble. Chandrayaan images were black and white.

They are missing have missed (on this mission atleast?) an outreach opportunity here. A picture of the Earth-moon system would've been awesome too.

"Mars mission is going well and will reach the orbit on September 24, 2014." This will make all in ISRO and also the people of the country proud "as it will be a major milestone for ISRO,"

Indian Space Research Organisation is likely to perform its next trajectory correction manoeuvre on its Mars Orbiter mission on June 11.

MOM Status Update

ISRO's Mars Orbiter spacecraft has traveled more than 460 million km distance in its 680 million km elliptical trajectory around Sun.
MOM is now at a distance of about 100 million km from planet Earth. The two way radio communication delay is approximately 11 minutes.


And, here's an update on trajectory correction manoeuvre scheduled at 4:30 PM IST, 11 June:
Quote
It will be 16 anxious seconds from 4.30 p.m. on Wednesday at the ISRO Telemetry, Tracking and Command Network (ISTRAC) Station, Bangalore, when ground controllers will correct the trajectory of India’s Mars Orbiter, speeding towards the Red Planet.

During the complex manoeuvre, the ground controllers will radio commands to the orbiter’s thrusters to fire for 15 or 16 seconds to correct its trajectory so that the spacecraft reaches the Martian orbit on the appointed day of September 24.

A missive from MOM confirms TCM2-Firing completion. Team MOM is busy crunching numbers to determine the post-TCM2 trajectory.

How many more does it have to preform before reaching Mars?

Two more trajectory corrections are planned (August and September), before Mars orbit insertion.
