When we hear the name SPACE, only one organization comes to mind: the Indian Space Research Organization (ISRO). The Indian Space Research Organization (ISRO), located in Bengaluru, is the country's first space agency. ISRO was founded in 1969 with the goal of developing and utilizing space technology for national development while also conducting planetary exploration and space science research. The space research operations began in India in the early 1960s, at a time when satellite applications were still in the experimental stages in the United States. Dr. Vikram Sarabhai, the founding father of India’s space programme, rapidly recognized the benefits of space technologies after the live transmission of the Tokyo Olympic Games across the Pacific by the American satellite ‘Syncom-3’ demonstrated the power of communication satellites. The ISRO has launched various spacecrafts like the Chandrayaan, Astrosat, Microsat, GSAT etc. The Government of India has also approved a regional spaceborne navigation system, which will consist of seven satellites. Out of these, four of them will be placed in geosynchronous inclined orbit of 29° relative to the equatorial plane. Such an arrangement would mean all seven satellites would have continuous radio visibility with Indian control stations.
Name the spacecraft that has been successfully sent into the space to probe into the planets in the solar system.
Correct Answer :
mariner 10
Solution :
The correct option is mariner 10.
Explanation:
Among the given options, Mariner 10 is a robotic space probe launched by NASA in November 1973 to study the planets Venus and Mercury. It made history as the first spacecraft to fly by multiple planets and provided the first close-up imagery of Mercury and Venus.
Let's briefly look at the other options:
• Sputnik 19: An attempted Soviet mission to Venus in 1962 that failed to escape Earth's orbit.
• Cosmos 482: A Soviet space probe launched in 1972 intended for a Venus flyby/landing, but it failed to leave low Earth orbit.
• Pioneer-E: A NASA probe intended to study solar radiation and inter-planetary space that was destroyed shortly after launch in 1969 due to a launch vehicle failure.
Therefore, Mariner 10 is the spacecraft that was successfully sent into space to probe planets in the solar system.
