ISRO Missions and Satellites

Aryabhatta was India's first satellite, launched on April 19, 1975. It was named after the ancient Indian mathematician-astronomer Aryabhata and was built by the Indian Space Research Organisation (ISRO). Bhaskara I and II were later satellites for remote sensing, while Rohini was a later launch vehicle series.

India's space agency ISRO launched the Aditya-L1 satellite to study the Sun. While other countries like USA and Russia have studied the Sun, this question refers to India's first dedicated solar mission launched in 2023.

Chandrayaan-I, India's first lunar mission, was successfully launched on October 22, 2008, using the PSLV-C11 rocket from Sriharikota. PSLV-C12 carried RISAT-2, PSLV-C10 carried IMS-1, and PSLV-12 is not a valid designation.

As of 2009-2010, ISRO had discussed 2020 as a target for India's first manned moon mission. However, these dates are projections that often change with space programs.

PSLV stands for Polar Satellite Launch Vehicle, an ISRO rocket designed to launch satellites into polar orbits. 'Public', 'Pulsar', and 'People' are incorrect expansions.

PSLV primarily launches satellites into Geostationary Transfer Orbit (GTO), despite its name emphasizing polar capability. Polar sun-synchronous is also common but GTO is the standard transfer orbit for communication satellites. 'Equitorial' and 'Oceanstationary' are not standard orbit terms.

STUDSAT (Student Satellite) was developed by Indian engineering students and launched by PSLV in 2010. It was India's first pico-satellite built by students. 'Studentsat', 'Studysat', and 'Indsat' are not the correct names.

Aryabhatta, launched on 19 April 1975, was India's first satellite. It was built by the Indian Space Research Organisation (ISRO) and named after the ancient Indian astronomer Aryabhata. The satellite conducted experiments in X-ray astronomy and solar physics.

Rakesh Sharma became the first Indian citizen to travel in space in 1984 as part of the Soviet Union's Intercosmos program. He flew aboard the Soyuz T-11 to the Salyut 7 space station. Kalpana Chawla and Sunita Williams were American astronauts of Indian origin. Neil Armstrong was American.

ISRO stands for Indian Space Research Organisation. Note the British spelling 'Organisation' with an 's', not 'Organization'. Other options either have incorrect words or spelling errors.

GAGAN (GPS-Aided Geo Augmented Navigation) is a joint venture between ISRO and the Airports Authority of India (AAI). It provides satellite-based navigation services for civil aviation. The system enhances GPS accuracy over Indian airspace. None of the other options (DRDO, BARC, IIT-B) are partners in this project.

Aryabhatta was India's first satellite, launched on April 19, 1975 by the Soviet Union. It was named after the ancient Indian mathematician-astronomer Aryabhata. Chandrayaan came much later (2008), while Arjun and Ashoka are not satellite names.
