Chandrayaan-4 mission: Check out the amazing ISRO objectives on the Moon
1/5 Collaborative Moon Mission: Japan and India have joined forces for a significant lunar exploration mission that is expected to launch in 2026 and it has been dubbed as Chandrayaan-4 mission, although the actual designation is the LUPEX project. This partnership, initiated in 2019 between the Japan Aerospace Exploration Agency (JAXA) and the Indian Space Research Organisation (ISRO) has certain aims. The Chandrayaan-4 mission objectives include the exploration of the lunar south pole. As far as the process is concerned about who contributes what, then know that ISRO will construct the moon lander, while JAXA will oversee the Chandrayaan-4 mission launch and provide the lunar rover.

2/5 Water Hunt on the Moon: The primary Chandrayaan-4 mission objective is to investigate the presence of water near the moon's south pole. The rover will be equipped with scientific instruments to autonomously search for water and even drill into the lunar surface to collect samples for analysis. (ISRO)

4/5 International Collaboration: In addition to Japan and India, other space agencies are contributing to the Chandrayaan-4 mission. NASA's Neutron Spectrometer will search for hydrogen below the moon's surface, while the European Space Agency's Exospheric Mass Spectrometer will assess gas pressure and chemical signatures on the lunar surface.

5/5 Expanding Lunar Exploration: The Chandrayaan-4 mission is part of a broader trend in lunar exploration, with various countries and space agencies actively pursuing lunar missions. Recent successes include India's Chandrayaan-3 mission along with the Vikram Lander and Pragyan Rover, NASA's Artemis program, and China's  moon mission. These missions will help expand our understanding of the Moon. (Pixabay)

Gaganyaan mission launch date: India's space agency, ISRO, is gearing up for an important milestone in its human spaceflight project, Gaganyaan. On October 21, 2023, ISRO will conduct the first test flight for the mission. The mission will demonstrate the crew escape system's performance, and it's set to take place between 7 am and 9 am from Sriharikota spaceport. The actual Gaganyaan mission launch date will be revealed at a later date.

The Gaganyaan project aims to prove India's capability for human spaceflight. It involves sending a human crew into orbit, 400 kilometers above Earth, and bringing them back safely by landing in the Indian Ocean. The upcoming Test Vehicle Development Flight (TV-D1) is a crucial step in this endeavor. It will test the crew module that will carry Indian astronauts during the actual human spaceflight scheduled for late next year, PTI reported.

The TV-D1 Test Flight

During the TV-D1 test flight, an unmanned crew module will be launched into space and then safely brought back to Earth, landing in the Bay of Bengal. After this first test flight, ISRO plans to conduct three more test missions, named D2, D3, and D4, to thoroughly examine the system's capabilities.

The test vehicle used for this mission is a single-stage liquid rocket designed for emergency abort situations. It includes the Crew Module (CM) and Crew Escape System (CES) with their fast-acting solid motors, along with the CM fairing (CMF) and Interface Adapters.

During the flight, the Crew Escape System and Crew Module will separate at an altitude of around 17 kilometers. After separation, the CES will execute an autonomous sequence, deploying a series of parachutes, ultimately leading to the safe landing of the CM in the sea, approximately 10 kilometers from the Sriharikota coast.

The crew module is a crucial part of the mission, where astronauts will stay in a pressurized, Earth-like atmosphere during the Gaganyaan mission. For the TV-D1 test, the CM is an unpressurized version that has undergone integration and testing. It is equipped with parachutes, recovery systems, and avionics for navigation, telemetry, and instrumentation.

After landing in the Bay of Bengal, a dedicated vessel and a diving team from the Indian Navy will be responsible for recovering the crew module.

The upcoming Gaganyaan mission test flight is a crucial step in this journey, demonstrating the technology and systems necessary to ensure astronauts' safety during their voyage into space and back to Earth.
