Times of India tracks the journey of India’s space agency, the Indian Space Research Organization (Isro):

1: The sounding rocket might have been launched from Thumba Equatorial Rocket Launching Station (TERLS) as early as 1963, with Vikram Sarabhai being the visionary mind behind Indian space programme, but the Indian Space Research Organisation (Isro) was officially created on Aug 15, 1969. A new campus at Veli, Thiruvananthapuram was set up in the same year.

2: Just about 6 years from creation of Isro, the launch of the first Indian satellite, Aryabhata, happens on April 19, 1975. Several other landmarks like operationalising SHAR Centre in Sriharikota (1971) rechristened as Satish Dhawan Space Centre in October 2003; establishment of the Department of Space (DOS) on June 1, 1972 with Satish Dhawan as the Secretary, and, establishment of the Isro Satellite Centre in Bangalore (1972).

3: Four years after Aryabhata, Isro launches Bhaskara, an experimental satellite for earth observations on June 7, 1979, and the first experimental launch of SLV-3 (launch vehicle) was done on August 10 the same year. But the satellite failed to reach the orbit. Many experiments including multiple attempts of launching SLV-3 and other satellites happened over the next eight years, including the launch of the first INSAT system on August 30, 1983.

4: Basking in the glory of the achievements, Isro experimented with the launch of ASLV, an advanced version of SLV-3 on March 24, 1987. But the satellite (SROSS-1) failed to reach the orbit. This was followed by a successful launch of INSAT-1D on June 12, 1990, which preceded the launch of the second operational Remote Sensing Satellite on August 29, 1991.

5: 1993: First developmental launch of what is today called Isro's workhorse launch platform, the Polar Satellite Launch Vehicle (PSLV) began. Even the PSLV's first attempt to put a satellite into orbit failed on September 20, 1993 This was followed by many communication and remote sensing satellites in the 90s. Isro saw success with PSLV, even began development of the Geo-synchronous Satellite Launch Vehicle (GSLV). GSLV, in fact, placed GSAT-1 satellite in orbit on April 18, 2001.

6: 2008: Isro launches a record Cartosat-2A and IMS-1 along with eight nano satellites (DELFI-C3 for the Netherlands; CUTE-1.7 and SEEDS for Japan; CAN-X2 and NLS-5 for Canada; AAUSAT-II for Denmark; COMPASS-I and RUBIN for Germany). Landmark project Chandrayaan also saw its launch on October 22, 2008 aboard the PSLV-C11.

7: November 5, 2013, Isro sent a probe to Mars at a cost of Rs 450-crore.

8: As India gears up for her date with the Red Planet, Isro's first interplanetary mission, the space agency holds the credit of having put in place the largest (civilian) constellation of remote sensing satellites, with 10 of them currently working in space.

9: September 24, 2014: Mars Orbiter Mission to be inserted into the Martian Orbit.

Crew module test: December

Scientists at the Satish Dhawan Space Centre in Sriharikota were busy integrating a brown bucket-like structure with a black lid mounted on a pedestal.Some day soon, they believe, an improved version of this would carry people to space. Indian Space Research Organisation (ISRO) took baby steps towards sending man to space, with an experimental flight of a GSLV-Mark III all set to carry this `crew module' as the payload in the sec ond week of December. While the manned mission is at least 10 years away , a full-fledged flight of GSLV-MIII is also a couple of years away . The biggest rocket to be made by ISRO, it can carry payloads up to four tonne-a necessity in the coming days of heavy satellites. Scientists are testing indigenously developed cryogenic engine at Isro's Mahendragiri facility.

The unmanned module to be used in Crew Module Atmospheric Re-entry Experiment (CARE) is to test its ability to re-enter the atmosphere with thermal resistance, parachute deployment in cluster formation, aero braking system and apex cover separation procedures.
