1st to 10th January 2024 - SUCCESSFUL INSERTION OF ADITYA- L1 TO HALO ORBIT Flashcards
What is Aditya-L1?
Aditya-L1 is an Indian spacecraft designed to study the Sun from a unique position at the Sun-Earth Lagrange point 1 (L1).
Where is Aditya-L1’s orbit located?
Approximately 1.5 million kilometers from Earth on the continuously shifting Sun-Earth line. It has an orbital period of roughly 177.86 Earth days.
Describe a halo orbit.
A halo orbit is a three-dimensional, teardrop-shaped orbit around a Lagrange point (like L1). It is not circular.
Why is a halo orbit ideal for Aditya-L1’s mission?
Unobstructed View: Provides a continuous, clear view of the Sun.
Fuel Efficiency: Requires minimal thruster adjustments, conserving fuel.
Scientific Advantage: Unique vantage point for solar observation and space weather studies.
What is a Lagrange point, specifically L1?
A Lagrange point is a location in space where the combined gravitational forces of two larger bodies (like the Sun and Earth) provide stability for a smaller object (like a spacecraft). L1 is the first Lagrange point between the Sun and Earth.
Why is L1 an advantageous position for solar observation?
L1 offers a location where a spacecraft can maintain a relatively stable position with a continuous view of the Sun, uninterrupted by Earth.
What is the primary goal of the Aditya-L1 mission?
To study the Sun’s atmosphere (photosphere, chromosphere, and corona), solar wind, and solar activity to improve our understanding of space weather.
How will data from Aditya-L1 benefit us?
This data will help scientists understand solar phenomena and their potential impacts on Earth’s communication systems, satellites, and technology.
