While the MOM is proceeding as planned, ISRO is launching the GSLV ( Geosynchronous Satellite Launch Vehicle ) on 5th January 2014, The GSLV has been a troublesome project for ISRO; with seven launches and three failures so far. the GSLV-D5 is the second time that India will be using an indigenous Cryogenic engine for the third stage, the first launch after the second stage failed to ignite. the payload for this mission is the GSAT-14 (Geosynchronous Satellite). A Live Telecast from Doordarshan and Webcast of the Launch will be available on Jan 05, 2014 from 15:52 hours (IST) onwards.

Note: this launch was originally scheduled for late 2013 but was delayed after a fuel leak.

This is an significant achievement for ISRO as this will reduce our reliance on the Ariane 5 Rocket for heavy payloads, and also puts in the market for launching Satellites (upto 2.5 tons) to Geo-stationary orbits. a Mark of accuracy was that they achieved an orbit which was accurate to about 40 meters at perigee and 5 KM at apogee.

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.

The second Trajectory Correction Manoeuvre (TCM-2) of India's Mars Orbiter Spacecraft was successfully performed on June 11, 2014 at 1630 hrs IST. TCM-2 was performed by firing the spacecraft’s 22 Newton thrusters for a duration of 16 seconds.

At present, the radio distance between the Spacecraft and the Earth is 102 million km. A radio signal from the Earth to the Spacecraft now takes about 340 seconds. The spacecraft so far has traveled a distance of 466 million km as part of its total Journey of 680 million km. ISRO is continuously monitoring Mars Orbiter Spacecraft using Indian Deep Space Network (IDSN). The spacecraft and its five scientific instruments are in good health.
