Making history in its space odyssey, India successfully launched its 100th mission with its PSLV-C21 placing in orbit two foreign satellites in a flawless flight from the spacement in Sriharikota.

A timeline of ISRO's major achievements:

1969-Indian Space Research Organisation (ISRO) formed on August 15.

1975-First Indian satellite, the Aryabhatta, launched into space on April 19.

1979-Bhaskara-1, an earth observation satellite launched. First experimental launch of satellite launch vehicle (SLV-3) carrying the Rohini satellite. The satellite is to placed in the orbit.

1980-Second experimental launch of SLV-3 with Rohini. Mission successful.

1982-Insat-1A communication satellite launched via a US Rocket.

1987-First developmental launch of Augmented SLV (ASLV) with satellite SROSS-1. Mission fails.

1988-Second developmental launch of Augmented SLV(ASLV) with satellite SROSS-1. Mission fails.

1992-First successful launch of ASLV placing SROSS-C satellite.

1993-First development launch of PSLV failed.

1997-First development launch of PSLV carrying IRS-1D.

2010-Launch of Risat-1 by PSLV: Launch of French satellite SPOT-6 and Japanese satellite PROITERES.

A teacher assigned a project to two groups consisting of two students each. The project was based on the topic Gravitation. He said that two freely falling bodies if dropped from the same height, take equal time to reach the ground. The groups had to confirm it by doing a practical. The next day when the teacher asked group one students, they said that they did the experiment and found that the results were in agreement with the statement of teacher. But the group two students found that the result were not in agreement with what their teacher had told.

Which group did the experiment correctly?
