Section 3: Pioneering Tech: Inside Chandrayaan 3.0

3.1 Advanced technologies present in Chandrayaan-3

Chandrayaan 3.0 , developed by the Indian Space Research Organisation (ISRO), is a lunar mission equipped with numerous advanced technologies, as follows:

1. Reinforced Legs: To enhance the chances of successful soft landing, the lander's legs have been robustly reinforced to handle higher landing velocities.

2. Thruster System: The lander comes with an independent thruster system for propulsion and control during different mission phases.

3. Navigational and Guidance Controls: Advanced navigational and guidance controls are incorporated in the lander for precise determination of its position, orientation, and movement.

4. Hazard Detection and Avoidance Systems: These systems are installed in the lander to identify potential lunar surface obstacles or hazards and take necessary avoidance actions.

5. SHAPE Payload: The propulsion module of Chandrayaan-3 carries the Spectro-polarimetry of Habitable Planet Earth (SHAPE) payload, which is aimed at studying spectral and polarimetric measurements of Earth from the lunar orbit.

ISRO's Chandrayaan 3.0's advanced technologies aim to improve mission performance, reliability, and safety, drawing upon lessons from Chandrayaan 2.0.

3.2 New Modules of Chandrayaan 3.0

ISRO Chandrayaan 3.0 mission comprises of three core components:

a) the indigenous Lander Module (LM), b) the Propulsion Module (PM), and c) Rover.

Designed to develop and demonstrate technologies for future interplanetary missions.

The Lander Module carries three payloads:

• The Chandra's Surface Thermophysical Experiment (ChaSTE) for measuring lunar surface thermal conductivity and temperature.

• The Instrument for Lunar Seismic Activity (ILSA) to measure seismicity around the landing site.

• The Langmuir Probe (LP) for estimating plasma density and variations.

• Notably, the Chandrayaan-3 Lander has been engineered with more fuel than Chandrayaan-2, allowing flexibility for last-minute landing site alterations.

• The lander's legs have been strengthened to withstand landing and stabilization speeds of up to 3 m/sec or 10.8 km/hour.

3.3 SHAPE Payload: Earth Study from Lunar Orbit

The Spectro-polarimetry of Habitable Planet Earth (SHAPE) payload on Chandrayaan 3.0 serves several purposes:

1. Spectral and Polarimetric Measurements: The payload will analyze spectral and polarimetric measurements of Earth from lunar orbit. This data will offer insights into the Earth's composition, temperature, and magnetic field.

2. Study of Earth's Atmosphere: By analyzing light reflected from Earth, SHAPE will provide valuable information about the Earth's atmosphere and its interaction with solar radiation.

3. Unique Vantage Point: Located on the propulsion module of Chandrayaan-3, which remains in lunar orbit, SHAPE offers a unique perspective for studying the Earth.

It's important to note that while SHAPE will significantly contribute to our understanding of Earth, its presence does not relate to Chandrayaan-3's primary objective— demonstrating safe lunar landing and roving capabilities.

Section 4: Delving Into India's Chandrayaan 3.0: Phases and Timeline

4.1 Exploring Phases of India's Chandrayaan 3.0

The three phases of the ISRO Chandrayaan 3.0 mission involve distinct movements and maneuvers:

1. Earth-centric phase: Known as Phase-1, this involves the pre-launch phase; the launch and ascent phase; and the Earth-bound maneuver phase. During this phase, Chandrayaan 3.0 orbits Earth five times, incrementally increasing its distance with each pass, aiding in changing the spacecraft's direction.

2. Lunar transfer phase: Also referred to as Phase-2, this stage sees the Chandrayaan-3 set on a lunar transfer trajectory, marking its journey towards the Moon.

3. Moon-centric phase: In Phase-3, Chandrayaan-3 enters the lunar orbit. The mission will then undergo four lunar orbits, each time coming closer to the Moon's surface.

This structured series of movements and maneuvers ensure a successful progression of the mission towards its objectives.

4.2 Unfolding the Timeline: India's Chandrayaan 3.0 Mission

The expected timeline for the Chandrayaan-3 mission includes the following key events:

1. Launch: The spacecraft was launched on July 14, 2023.

2. Journey to the Moon: The journey from Earth to the Moon is approximately one month.

3. Lunar Landing: The lander and rover are anticipated to land near the lunar south pole region on August 23-24, 2023.

4. Mission Operations: Post landing, the lander and rover will commence operations, demonstrating successful landing and roving capabilities on the lunar surface.

Please bear in mind that these timelines may vary due to factors such as technical readiness, launch preparations, and specific mission requirements. For the most accurate and updated information, it is recommended to refer to official ISRO announcements and updates.

Section 5: ISRO's Journey Through Lunar Missions: Chandrayaan 1.0 to 3.0.

5.1 ISRO's Lunar Odyssey: Chandrayaan 1.0 to 3.0

Chandrayaan-1, Chandrayaan-2, and Chandrayaan-3 are all lunar exploration missions developed by the Indian Space Research Organisation (ISRO).

• Chandrayaan-1 (2008): The first Indian lunar probe under the Chandrayaan programme. It consisted of a lunar orbiter and an impactor. The mission's crowning achievement was discovering the widespread presence of water molecules in lunar soil.

• Chandrayaan-2 (2019): This mission comprised a lunar orbiter, a lander, and the Pragyan rover. The main scientific goal was to map and study variations in lunar surface composition and the location and abundance of lunar water. The lander, however, crashed during the landing attempt.

• Chandrayaan-3 (2023): The third lunar exploration mission, comprised of a lander and the Pragyan rover, but not an orbiter. Instead, its propulsion module acts as a communication relay satellite. The launch took place on 14 July 2023, with a successful lunar injection completed as part of phase one. The lander and rover are scheduled to land near the lunar south pole region on 23 August 2023.

5.2 Comparing ISRO's Chandrayaan 2.0 and 3.0 Missions

The lunar missions Chandrayaan-2 and Chandrayaan-3, orchestrated by the Indian Space Research Organisation (ISRO), share similarities but also contain key differences:

1. Payload: Chandrayaan-2 comprised of an orbiter, a lander (Vikram), and a rover (Pragyan). However, Chandrayaan-3 includes only a lander and a rover. The orbiter from Chandrayaan-2 will meet Chandrayaan-3's communication and mapping needs.

2. Mission Objective: Chandrayaan-2 aimed to explore lunar surface composition and the location and abundance of lunar water. Chandrayaan-3, however, primarily aims to demonstrate safe landing and lunar surface roving abilities.

3. Launch Vehicle: Both missions utilized the GSLV Mk III rocket for launch. Yet, the rocket configuration and the spacecraft trajectory might differ in the latter.

4. Lander Design: Chandrayaan-3's lander design has been improved, including sturdier legs to withstand higher landing velocities, based on lessons learned from Chandrayaan-2.

5. Timeline: Chandrayaan-2 launched on July 22, 2019, with the orbiter reaching lunar orbit on September 2, 2019. Chandrayaan-3's launched on 14th Jul 2023.

In conclusion, although the two missions share aspects like the GSLV Mk III rocket usage, they diverge in various ways. Chandrayaan-3's primary objective contrasts that of Chandrayaan-2, focusing on demonstrating safe lunar landing and roving, without an orbiter.

5.3 Design Evolution: Chandrayaan 3.0 vs. Its Predecessor

Chandrayaan-3 incorporates a range of significant design modifications compared to its predecessor, Chandrayaan-2:

1. Enhanced Propulsion and Trajectory Management: New instruments and algorithms have been introduced to manage failures and handle unexpected deviations in propulsion or trajectory.

2. Heavier Lander: The lander is designed to be heavier and comes with stronger legs to manage an additional velocity of approximately 1 meter per second.

3. Bigger Solar Panels: Larger solar panels have been integrated to enable more efficient energy collection and usage.

4. Additional Fuel: The spacecraft carries more fuel to ensure sufficient resources for its extended mission.

5. Advanced Sensors: The mission includes new sensors designed to precisely measure the spacecraft's velocity relative to the Moon.

6. Improved Landing Software: An upgraded software has been installed to enhance guidance during the landing phase.

These modifications aim to enhance the mission's chances of successfully landing on the lunar surface.
