On 23 August 2023, as the lander approached the low point of its orbit, its four engines fired as a braking manoeuvre at {{convert|30|km|mi}} above the Moon's surface. After 11.5 minutes, the lander was 7.2 km (4.5 miles) above the surface; it maintained its altitude for about 10 seconds, then stabilized itself using eight smaller thrusters and rotated from a horizontal to a vertical position while continuing its descent.

Chandrayaan-3 (transl. Moon-craft, Hindi: [t͡ʃən̪d̪rəjaːn̪] (About this soundlisten))[6] is the third Indian lunar exploration mission under the Indian Space Research Organisation's (ISRO) Chandrayaan programme.[6] It consists of a lander named Vikram and a rover named Pragyan, similar to those of the Chandrayaan-2 mission. The propulsion module carried the lander and rover configuration to lunar orbit in preparation for a powered descent by the lander.[7][8]

Chandrayaan-3 was launched on 14 July 2023. The lander and rover landed at the lunar south pole region[9] on 23 August 2023 at 18:02 IST, making India the first country to successfully land a spacecraft near the lunar south pole[10] and the fourth country to soft-land on the Moon.[11][12][13][14]

Background

On 22 July 2019, ISRO launched Chandrayaan-2 on board a Launch Vehicle Mark-3 (LVM3) launch vehicle consisting of an orbiter, a lander and a rover.[15] The lander was scheduled to touch down on the lunar surface in September 2019 to deploy the Pragyan rover. The lander ultimately crashed when it deviated from its intended trajectory while attempting to land.[16][17]

Following Chandrayaan-2, Chandrayaan-3 and further lunar missions were proposed.[18]

The European Space Tracking network (ESTRACK), operated by the European Space Agency (ESA), is supporting the mission. Under a new cross-support arrangement, ESA tracking support could be provided for upcoming ISRO missions such as those of India's first human spaceflight programme, Gaganyaan, and the Aditya-L1 solar research mission. In return, future ESA missions will receive similar support from ISRO's own tracking stations.[19]

Objectives

ISRO's mission objectives for the Chandrayaan-3 mission were:

  1. Getting a lander to land safely and softly on the surface of the Moon.
  2. Observing and demonstrating the rover's driving capabilities on the Moon.
  3. Conducting and observing experiments on the materials available on the lunar surface to better understand the composition of the Moon.[20]

Spacecraft

Design

Chandrayaan-3 comprised three main components:

Propulsion module
The propulsion module carries the lander and rover configuration to a 100 kilometres (62 mi) lunar orbit. It is a box-like structure with a large solar panel mounted on one side and a cylindrical mounting structure for the lander (the Intermodular Adapter Cone) on top.[8][7]
Lander
The Vikram lander is responsible for the soft landing on the Moon. It is also box-shaped, with four landing legs and four landing thrusters capable of producing 800 newtons of thrust each. It carries the rover and various scientific instruments to perform on-site analysis.[21][22]
The lander for Chandrayaan-3 has four variable-thrust engines with slew rate changing capabilities, unlike Chandrayaan-2's lander, which had five, with the fifth one being centrally mounted and capable only of fixed thrust. One of the main reasons for Chandrayaan-2 landing failure, attitude increase during the camera coasting phase, was removed by allowing the lander to control attitude and thrust during all phases of descent. Attitude correction rate is increased from Chandrayaan-2's 10°/s to 25°/s with Chandrayaan-3. Additionally, the Chandrayaan-3 lander will be equipped with a Laser Doppler Velocimeter (LDV) to allow measuring attitude in 3 directions.[23][24] The impact legs have been made stronger compared to Chandrayaan-2 and instrumentation redundancy has been improved. It will target a more precise 4 km (2.5 mi) by 4 km (2.5 mi) landing region based on images previously provided by the Orbiter High-Resolution Camera (OHRC) onboard Chandrayaan-2's orbiter. ISRO improved the structural rigidity, increased polling in instruments, increased data frequency and transmission, and added additional multiple contingency systems to improve lander survivability in the event of failures during descent and landing.[25][24]
Rover
The Pragyan rover is a six-wheeled vehicle with a mass of 26 kilograms (57 pounds). It is 917 millimetres (3.009 ft) x 750 millimetres (2.46 ft) x 397 millimetres (1.302 ft) in size.[26]
The rover is expected to take multiple measurements to support research into the composition of the lunar surface, the presence of water ice in the lunar soil, the history of lunar impacts, and the evolution of the Moon's atmosphere.[27][9]

Payloads

Lander

  • Chandra's Surface Thermophysical Experiment (ChaSTE) will measure the thermal conductivity and temperature of the lunar surface.
  • Instrument for Lunar Seismic Activity (ILSA) will measure the seismicity around the landing site.
  • Langmuir Probe (LP) will estimate the near-surface plasma density over time.[28]

Rover

  • Alpha Particle X-Ray Spectrometer (APXS) will derive the chemical composition and infer the mineralogical composition of the lunar surface.
  • Laser-Induced Breakdown Spectroscope (LIBS) will determine the elemental composition (Mg, Al, Si, K, Ca, Ti, Fe) of lunar soil and rocks around the lunar landing site.[28]

Propulsion module

  • Spectro-polarimetry of Habitable Planet Earth (SHAPE) will study spectral and polarimetric measurements of Earth from the lunar orbit in the near-infrared (NIR) wavelength range (1–1.7 μm [3.9×10−5–6.7×10−5 in]).[8][7]

Launch

LVM3 M4, Chandrayaan-3 – Launch vehicle lifting off from the second launch pad of SDSC-SHAR, Sriharikota

Chandrayaan-3 was launched aboard an LVM3-M4 rocket on 14 July 2023, at 2:35 pm IST from Satish Dhawan Space Centre Second Launch Pad in Sriharikota, Andhra Pradesh, India, entering an Earth parking orbit with a perigee of 170 km (106 mi) and an apogee of 36,500 km (22,680 mi).

Orbit

After a series of manoeuvres that placed Chandrayaan-3 in a trans-lunar injection orbit,[29][30][31] ISRO performed a lunar-orbit insertion (LOI) on 5 August, successfully placing the Chandrayaan-3 spacecraft into orbit around the Moon. The LOI operation was carried out from the ISRO Telemetry, Tracking, and Command Network (ISTRAC) located in Bengaluru.[32][33]

On 17 August, the Vikram lander separated from the propulsion module to begin the last phase of the mission.[34]

Descent

On 23 August 2023, as the lander approached the low point of its orbit, its four engines fired as a braking manoeuvre at 30 kilometres (19 mi) above the Moon's surface. After 11.5 minutes, the lander was 7.2 km (4.5 miles) above the surface; it maintained its altitude for about 10 seconds, then stabilized itself using eight smaller thrusters and rotated from a horizontal to a vertical position while continuing its descent.

It then used two of its four engines to slow its descent to roughly 150 metres (490 ft); it hovered there for about 30 seconds before continuing downward and touching down at 12:32 UTC.[35][36]

Funding

In December 2019, ISRO requested the initial funding of the project, amounting to 75 crore (US$8.6 million), out of which 60 crore (US$6.9 million) would be for meeting expenditure towards machinery, equipment, and other capital expenditure, while the remaining 15 crore (US$1.7 million) was sought for operating expenditure.[57]

Confirming the existence of the project, ISRO's former chairman K. Sivan stated that the estimated cost would be around 615 crore (US$71 million).[58][59][60]
