-
Bhaskara I
-
Aryabhatta
-
Bhaskara II
-
Rohini
B
Correct answer
Explanation
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.

-
Global Sattelite Launch Vehicle
-
Geosynchronous Sattelite Launch Vehicle
-
Geological Sattelite Launch Vehicle
B
Correct answer
Explanation
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.

PSLV-C10
-
PSLV-12
B
Correct answer
Explanation
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.
A
Correct answer
Explanation
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.

Public Satellite Launch Vehicle
-
Polar Satellite Launch Vehicle
-
Pulsar Satellite Launch Vehicle
-
People Satellite Launch Vehicle
B
Correct answer
Explanation
PSLV stands for Polar Satellite Launch Vehicle, an ISRO rocket designed to launch satellites into polar orbits. 'Public', 'Pulsar', and 'People' are incorrect expansions.
-
Polar transfer orbit
-
geostationary transfer orbit
-
Equitorial transfer orbit
-
Oceanstationary transfer orbit
B
Correct answer
Explanation
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.
-

D
Correct answer
Explanation
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.

Bhaskara-I
-
Rohini RS-1
C
Correct answer
Explanation
Bhaskara-I, launched in 1979, was indeed India's first satellite specifically designed for TV and microwave telecommunications experiments. Aryabhatta (1975) was India's first satellite overall but was a scientific research satellite without TV/microwave payloads. The Rohini series came later in the 1980s.

C
Correct answer
Explanation
Aryabhatta was India's first satellite, launched on 19 April 1975. It was built by the Indian Space Research Organisation (ISRO) and named after the ancient Indian mathematician-astronomer Aryabhata. Rohini was a later satellite series (first launched in 1979). SLV (Satellite Launch Vehicle) was the launch vehicle, not a satellite. PSLV (Polar Satellite Launch Vehicle) is an operational launch vehicle first flown in 1993, not a satellite.
