Consider the following statements. Variations in the Solar weather can...
Explanation:
Let's analyze each statement one by one:
1. Variations in Solar weather can change the orbits of satellites or shorten their lives.
- This statement is correct. Solar weather refers to the conditions and activity on the Sun, such as solar flares and coronal mass ejections. These events can release charged particles and electromagnetic radiation, which can affect satellites in various ways. Changes in solar weather can cause drag on satellites, altering their orbits and potentially shortening their operational lives.
2. A satellite placed in the halo orbit around Lagrangian Point 1 (L1) of the Sun-Earth system has the advantage of continuously viewing the Sun without any occultation.
- This statement is correct. The Lagrange points are positions in space where the gravitational forces of two large bodies, such as the Sun and Earth, balance the centrifugal force felt by a smaller object. The L1 point is located between the Sun and Earth, and satellites placed in a halo orbit around this point can have a continuous view of the Sun without any interruption due to occultation (when an object passes in front of another, blocking its view).
3. Satellites placed in the Lagrange Points require more fuel to remain in position.
- This statement is incorrect. Satellites placed in the Lagrange Points actually require less fuel to maintain their positions compared to satellites in other orbits. This is because the Lagrange Points are areas of gravitational stability, where the gravitational forces from the Sun and Earth balance out. Once a satellite is placed in a Lagrange Point, it requires minimal fuel to make small adjustments to maintain its position.
Based on the analysis above, we can conclude that only two of the given statements are correct, which corresponds to option B.

Statement 3 is incorrect.
- The solar weather and environment affect the weather of the entire system. Variations in this weather can change the orbits of satellites or shorten their lives, interfere with or damage onboard electronics, and cause power blackouts and other disturbances on Earth. Knowledge of solar events is key to understanding space weather.
- Every storm that emerges from the Sun and heads towards Earth passes through L1, and a satellite placed in the halo orbit around L1 of the Sun-Earth system has the major advantage of continuously viewing the Sun without any occultation/eclipses.
- L1 refers to Lagrangian/Lagrange Point 1, one of five points in the orbital plane of the Earth-Sun system. Lagrange Points, named after Italian-French mathematician Josephy-Louis Lagrange, are positions in space where the gravitational forces of a two-body system (like the Sun and the Earth) produce enhanced regions of attraction and repulsion. These can be used by spacecraft to reduce fuel consumption needed to remain in position. The L1 point is home to the Solar and Heliospheric Observatory Satellite (SOHO), an international collaboration project of NASA and the European Space Agency (ESA).
