100 Days of Mars mission by ISRO

Mars Orbiter Spacecraft, India's first interplanetary probe, was launched by PSLV C25 at 1438 hours on November 05, 2013 from Satish Dhawan Space Centre, Sriharikota. In its voyage towards Mars, the mission successfully completes 100 days in space tomorrow (February 12, 2014).

Subsequent to six orbit raising manoeuvres around the Earth following the launch, the Trans Mars Injection (TMI) Manoeuvre on December 01, 2013 gave necessary thrust to the spacecraft to escape from Earth and to initiate the journey towards Mars, in a heliocentric Orbit. This journey, of course, is long wherein the spacecraft has to travel 680 million km out of which a travel of 190 million km is completed so far.

The First Trajectory Correction Manoeuvre (TCM) was conducted on December 11, 2013. The trajectory of the spacecraft, till today, is as expected. Three more TCM operations are planned around April 2014, August 2014 and September 2014.

The spacecraft health is normal. The spacecraft is continuously monitored by the ground station of ISRO Telemetry, Tracking and Command Network (ISTRAC), located at Byalalu, near Bangalore. Except for a 40 minute break in the Telemetry data received from the spacecraft to the ground station, data has been continuously available for all the 100 days.

The propulsion system of the spacecraft is configured for TCMs and the Mars Orbit Insertion (MOI) Operation. On February 06, 2014, all the five payloads on Mars Orbiter spacecraft were switched 'ON' to check their health.

The health parameters of all the payloads are normal. Presently, the spacecraft is at a radio distance of 16 million km causing a one way communication delay of approximately 55 seconds. After travelling the remaining distance of about 490 million km over the next 210 days, the spacecraft would be inserted into the Martian Orbit on September 24, 2014.

Indigenous Cryogenic Upper Stage Successfully Flight Tested On-board GSLV-D5:ISRO

The Indigenous Cryogenic Upper Stage was successfully flight-tested onboard GSLV-D5 launch vehicle on January 05, 2014 from Satish Dhawan Space Centre SHAR, Sriharikota. In this successful flight of GSLV-D5, a communication satellite - GSAT-14 - was launched very precisely to its intended Geosynchronous Transfer Orbit.

After a smooth countdown of 29 hours, GSLV-D5 lifted off at 1618 hours IST at the opening of the launch window. All the important flight phases, namely, the core stage and strap-on stage propulsion, payload fairing separation, second stage propulsion, cryogenic stage propulsion and spacecraft separation, were executed as planned.

After a flight of 17 minutes 5 seconds, GSAT-14 satellite was precisely injected into a Geosynchronous Transfer Orbit with a Perigee (nearest point to Earth) of 175 km and an Apogee (farthest point to Earth) of 35,945 km with an orbital inclination of 19.3 degree with respect to the equator.

Immediately after the injection, ISRO's Master Control Facility at Hassan took over the control and commanding of GSAT-14. The solar panels of the satellite were deployed as planned, the satellite health was found normal and the satellite was oriented towards the Sun. The first orbit raising operation of GSAT-14 is planned at 0758 hrs IST on January 6, 2014. The remaining two orbit raising operations are planned on January 7 and 9, 2014 to place the satellite in geostationary orbit.

PM congratulates ISRO on the successful launch of GSLV D5

The Prime Minister, Dr. Manmohan Singh, has congratulated the scientists and engineers of Indian Space Research Organization (ISRO) for the successful launch of GSLV D5 carrying GSAT-14 payload. Commending ISRO for the successful launch, he described it as yet another important step that the country has taken in the area of science and technology.

The Geosynchronous Satellite Launch Vehicle GSLV-D5 was launched from the Satish Dhawan Space Centre in Sriharikota today. It includes an indigenous cryogenic rocket stage.


History has been created...! GSLV D5 with Indigenous Cryogenic Stage Successfully Launches GSAT 14 Satellite from Satish Dhawan Space Centre, SHAR, Sriharikota on January 05, 2014....ISRO

GSAT 14 Mission Profile
After its injection into Geosynchronous Transfer Orbit (GTO) by GSLV D5, ISRO’s Master Control Facility (MCF) at Hassan takes control of GSAT 14 and performs the initial orbit raising manoeuvres in three steps, firing the satellite's Liquid Apogee Motor (LAM), finally placing it in the circular Geostationary Orbit. Following this, the deployment of the antennae and three axis stabilisation of the satellite will be performed. GSAT 14 will be positioned at 74 deg East longitude and co-located with INSAT 3C, INSAT 4CR and KALPANA 1 satellites. The 12 communication transponders onboard GSAT 14 will further augment the capacity in the INSAT / GSAT system.

India’s advanced multi-band communication satellite GSAT-7 placed in Geosynchronous Orbit

India’s advanced multi-band communication satellite GSAT-7, launched from Kourou, French Guiana in the early hours of August 30, 2013, has been successfully placed in the Geosynchronous Orbit with an altitude of about 36,000 km above Earth’s surface yesterday (September 3, 2013) morning, after successfully completing the last of the three orbit-raising manoeuvres commanded from ISRO's Master Control Facility (MCF) at Hassan.

Later in the day, the communication antennae of GSAT-7, including the UHF Helix antenna, were deployed successfully. Following this, GSAT-7 was put in its final orbital configuration, stabilised on its three-axis by the momentum wheels.

The GSAT-7 Satellite would reach its assigned orbital slot of 74 degree East longitude in the Geostationary Orbit within the next 10 days. On September 14, 2013, the communication transponders in UHF, S, C and Ku bands are planned to be switched on.

Based on current availability of hardware and components, the GSLV Vehicle assembly and checkout is expected to be completed at the Vehicle Assembly Building by the first week of December 2013 and the launch could take place by December 2013.

GSLV-D5 launch could take place in December 2013

The launch of GSLV-D5 (with Indian Cryogenic Stage), scheduled for 1650 hrs on August 19, 2013, had to be called off due to a leak observed in the UH25 Fuel system of the Liquid Second Stage, during the last lap of the countdown. At the time of calling off the Countdown, the GSLV Vehicle was loaded with 210 tons of liquid and cryogenic propellants. About 750 kg of UH25 Fuel had leaked out, leading to contamination of the area around the launch pad. It took 6 days of round-the-clock operations before the contamination could be reduced to the safe level to enable movement of the GSLV-D5 back to the Vehicle Assembly Building. The GSLV-D5 Launch Vehicle has been safely moved back to the Vehicle Assembly Building on the early morning of August 26, 2013. The Vehicle has been de-stacked.
Chairman, ISRO constituted a High Level Task Team on August 20, 2013, chaired by Shri K. Narayana, (former Director of Satish Dhawan Space Centre) to identify the cause of the leak and to work out an action plan for quick restoration of the Mission, taking into account the safety, reliability and life of the Liquid Second Stage and the four Liquid Strap-on stages, which were wetted with liquid propellants. The leak is suspected to be in the lower portion of the propellant tank or the fluid lines between the tank and fuel filling system of the Second stage. Detailed investigation of the leak is underway.
The following action plan is put in place:
A new Liquid Second Stage (GS-2) is being assembled to replace the leaked-stage. All the four Liquid Strap-on Stages are being replaced with new ones. The First Stage (Solid) and core base shroud are being inspected and the elements that are affected will be replaced. The Satellite Assembly, Avionics Equipment Bay and the Cryogenic Stage will be preserved, following prescribed practices.
Based on current availability of hardware and components, the GSLV Vehicle assembly and checkout is expected to be completed at the Vehicle Assembly Building by the first week of December 2013 and the launch could take place by December 2013.
