The [1] space craft which is headed to the Lagrangian point has escaped the sphere of Earth’s influence. [1] is India’s first space-based observatory to study the Sun.” The spacecraft has travelled beyond a distance of 9.2 lakh kilometres from Earth, successfully escaping the sphere of Earth’s influence. It is now navigating its path towards the Sun-Earth Lagrange Point,”. The space agency added that this is the second time in succession that it could send a spacecraft outside the sphere of influence of the Earth, the first time being the Mars Orbiter Mission. [1] was launched on September 2. Following the launch ISTRC carried out four earth-bound manoeuvres between September 3 and September 15. [1] which is dedicated to the comprehensive study of the Sun has seven payloads. Five payloads were developed by ISRO and two by Indian academic institutes in collaboration with the space agency. Upon arrival at the L1 point in January 2024, another manoeuvre will be performed which will bind [1] to an orbit around L1. The satellite will spend its mission life orbiting around L1 in an irregularly shaped orbit in a plane roughly perpendicular to the line joining the Earth and the Sun. [1] has a mission life of five years during which its payloads are expected to provide the most crucial information to understand the problem of coronal heating; coronal mass ejection; pre-flare and flare activities and their characteristics; dynamics of space weather; and propagation of particles and fields.

Question1:- Which of the following is the first space based Indian mission to study the Sun, launched in early September 2023 and is redacted as [1] in the above passage?
  • A. Gaganyaan 1
  • B. Aditya L1
  • C. Solar Orbiter
  • D. Mangalyaan
Answer is B is correct. Aditya L1 is the first space based Indian mission to study the Sun. The spacecraft shall be placed in a halo orbit around the Lagrange point 1 (L1) of the Sun-Earth system, which is about 1.5 million km from the Earth. It was launched by ISRO on September 2, 2023 via Satish Dhawan Space centre. Hence, B is the correct option.
Question2:-The India’s first space-based sun mission is launched from which space agency?
  • A. Satish Dhawan Space Centre
  • B. Vikram Sarabhai Space centre
  • C. Indian institute of remote sensing
  • D. None of the above
Answer is A is correct. India's first solar observatory mission Aditya-L1 was launched by the Indian Space Research Organisation (ISRO) on September 2. The Polar Satellite Launch Vehicle (PSLV), in its 59 th flight with the Aditya-L1 onboard, took off from the Satish Dhawan Space Centre in Sriharikota at 11.50 a.m. Hence, A is the correct option.
Question3:-Which of the following is the India’s first space mission launched by ISRO?
  • A. Rohini
  • B. Aryabhata
  • C. INSAT
  • D. PSLV
Answer is B is correct. Aryabhata. The Aryabhata spacecraft, named after the famous Indian astronomer, was India first satellite and first space mission, it was completely designed and fabricated in India and launched by a Soviet Kosmos-3M rocket from Kapustin Yar on April 19, 1975. Hence, B is the correct option.
Question4:-Which of the following country has become the fifth nation following India’s success to achieve a soft landing on moon’s surface after launching a rocket carrying ‘Moon Sniper’ lunar lander?
  • A. China
  • B. Russia
  • C. Japan
  • D. Israel
Answer is C is correct. Successful launch comes after India became the fourth country to land on the moon with its Chandrayaan-3 mission. Japan has launched a rocket carrying a lunar exploration spacecraft named as ‘Moon sniper’ and like this the country became the world fifth to land on the moon. Hence, C is the correct option.
Question5:-Which of the following is the ISRO’s next lunar mission in collaboration with JAXA, a Japanese space agency which to be launched in the year between 2024-2025?
  • A. JUNEX
  • B. LUPEX
Answer is B is correct. As of now, ISRO is preparing for one more lunar mission, this one in collaboration with Japanese space agency, JAXA. This mission, called LUPEX, or Lunar Polar Exploration, is slated for 2024-25. But there would be more in the Chandrayaan series as well. Hence, B is the correct option.
