Q. Consider the following:
  1. Parker Solar Probe
  2. Voyager 1
  3. New Horizons
  4. Juno
Which of the following is the correct order of these space probes launched by NASA from earliest to latest?

Answer: 2 1 4 3
Notes: Voyager 1 was launched in 1977, making it the first among these probes. It was followed by the launch of Parker Solar Probe in 2018, which is designed to study the Sun. Juno, which focuses on Jupiter, was launched in 2011, and New Horizons, known for its flyby of Pluto, was launched in 2006. Thus, the correct order is 2 (Voyager 1), 1 (Parker Solar Probe), 4 (Juno), 3 (New Horizons). Thus, the correct order is 2 1 4 3.
