Key Milestones in Mars Exploration & InSight's Discovery
This timeline illustrates the progression of Mars exploration missions, highlighting significant achievements and placing NASA's InSight lander's discovery of Mars's active electrical environment in historical context.
Mars exploration began in the 1960s, evolving from flybys to orbiters, landers, and sophisticated rovers. Each mission has built upon previous discoveries, progressively revealing more about Mars's geology, atmosphere, and potential for past or present life. InSight, primarily focused on the planet's interior, has now provided crucial insights into its active electrical environment, adding a new dimension to our understanding of Martian atmospheric processes and potential challenges for future human missions.

सारांश
New research indicates that Mars possesses an active electrical environment, with phenomena like dust devils generating significant electrical activity. This discovery, made through data from NASA's InSight lander, suggests that the Martian atmosphere is more electrically charged than previously thought.
Understanding this electrical environment is crucial for future human and robotic missions to Mars, as it could affect sensitive electronic equipment and pose challenges for astronaut safety. It also provides insights into the planet's atmospheric processes and potential for life.
पृष्ठभूमि
Mars has been a subject of intense scientific inquiry for decades, with numerous missions aimed at understanding its geology, atmosphere, and potential for life. Early missions like Viking provided initial atmospheric data, while subsequent orbiters and landers (e.g., Pathfinder, Spirit, Opportunity, Curiosity, Perseverance) have progressively revealed more about its surface and subsurface conditions.
The presence of water, past geological activity, and the thin CO2-rich atmosphere have been key areas of study. The InSight lander, launched in 2018, was specifically designed to study the deep interior of Mars, focusing on seismology and heat flow.

बहुविकल्पीय प्रश्न (MCQ)
1. Consider the following statements regarding the recent discovery of an active electrical environment on Mars: 1. The discovery was primarily made using data from NASA's InSight lander. 2. Dust devils are identified as a significant contributor to this electrical activity. 3. InSight's primary mission focused on studying the Martian atmosphere's upper layers and exosphere. Which of the statements given above is/are correct?
- A.1 only
- B.1 and 2 only
- C.2 and 3 only
- D.1, 2 and 3
उत्तर देखें
सही उत्तर: B
Statement 1 is correct: The discovery of an active electrical environment on Mars was indeed made through data from NASA's InSight lander. Statement 2 is correct: The research indicates that dust devils generate significant electrical activity. Statement 3 is incorrect: InSight's primary mission was to study the deep interior of Mars, focusing on seismology and heat flow, not the upper atmosphere or exosphere.
2. In the context of the Martian environment and its implications for future missions, consider the following statements: 1. Mars possesses a global intrinsic magnetic field, similar to Earth, which protects its atmosphere from solar wind erosion. 2. The Martian atmosphere is predominantly composed of carbon dioxide, leading to a significant greenhouse effect comparable to Earth's. 3. The newly discovered electrical environment could pose risks to sensitive electronic equipment and astronaut safety due to electrostatic discharges and dust adhesion. Which of the statements given above is/are correct?
- A.1 and 2 only
- B.2 and 3 only
- C.3 only
- D.1, 2 and 3
उत्तर देखें
सही उत्तर: C
Statement 1 is incorrect: Mars does not possess a global intrinsic magnetic field like Earth. It has only localized crustal magnetic fields, which offer very limited protection from solar wind. Statement 2 is incorrect: While the Martian atmosphere is predominantly carbon dioxide (about 95%), it is extremely thin (less than 1% of Earth's atmospheric pressure). Therefore, the greenhouse effect is minimal and not comparable to Earth's. Statement 3 is correct: The news explicitly states that understanding this electrical environment is crucial as it could affect sensitive electronic equipment and pose challenges for astronaut safety due to phenomena like electrostatic discharges and dust adhesion.
3. Which of the following pairs of Mars missions and their primary objectives/instruments is/are correctly matched? 1. InSight: Study the deep interior of Mars using a seismometer. 2. Perseverance: Collect rock and soil samples for potential return to Earth. 3. Mangalyaan (MOM): Search for signs of past or present microbial life on the surface. Select the correct answer using the code given below:
- A.1 only
- B.1 and 2 only
- C.2 and 3 only
- D.1, 2 and 3
उत्तर देखें
सही उत्तर: B
Pair 1 is correctly matched: InSight's primary mission was indeed to study the deep interior of Mars, using instruments like a seismometer (SEIS) and a heat flow probe (HP3). Pair 2 is correctly matched: NASA's Perseverance rover's key objective is to collect rock and soil samples, cache them on Mars, and prepare them for a future sample return mission to Earth. Pair 3 is incorrectly matched: India's Mars Orbiter Mission (Mangalyaan) was primarily a technology demonstrator mission to develop technologies required for designing, planning, management, and operations of an interplanetary mission. Its scientific objectives included studying the Martian surface features, morphology, mineralogy, and the Martian atmosphere, particularly searching for methane, but not specifically searching for signs of microbial life on the surface, which is a more direct objective of rovers like Perseverance or the European ExoMars rover.
