In a monumental achievement for the Indian Space Research Organization (ISRO), the Chandrayaan-3 rover has successfully identified traces of sulfur, oxygen, titanium, and other elements on the moon’s South Pole. This revelation comes after the rover’s triumphant landing on the South Pole on August 23, marking India as the first nation to achieve this feat. This groundbreaking discovery was made possible by the Laser-Induced Breakdown Spectroscopy (LIBS) instrument onboard Chandrayaan-3, which analyzes the composition of materials by exposing them to intense laser pulses. While this is only a preliminary analysis, ISRO has confirmed the unambiguous presence of sulfur.

But the moon is not the only celestial body that India has its sights set on. The ISRO has announced that its first mission to the sun, Aditya-L1, is scheduled to launch on September 2. This ambitious mission aims to study solar winds, which can have significant impacts on astronauts and technology. The Aditya-L1 will be delivered 1.5 million miles to the sun aboard a massive four-stage rocket launching from an island on India’s eastern coast. The spacecraft is outfitted with seven payloads to observe the sun’s photosphere, chromosphere, and outermost layers, known as the corona, using electromagnetic, particle, and magnetic field detectors. This mission comes hot on the heels of the Chandrayaan-3’s success, demonstrating India’s growing prowess in the field of space exploration.

From Moon to Sun: India’s Journey in Space Exploration

India’s recent explorations in space have brought about exciting scientific findings and marked significant milestones. The Indian Space Research Organization’s (ISRO) Chandrayaan-3 lunar rover has made a successful landing at the moon’s South Pole, detecting a number of elements including sulfur, oxygen, and titanium. Meanwhile, the nation is gearing up to launch its first mission to the sun, marking another leap in its space exploration endeavors.

Chandrayaan-3: Unveiling the Secrets of the Moon’s South Pole

On August 23, the Chandrayaan-3 rover touched down on the moon’s South Pole, an unexplored region. The rover detected traces of sulfur, in addition to aluminum, iron, calcium, chromium, titanium, manganese, oxygen, and silicon. This detection was possible thanks to the Laser-Induced Breakdown Spectroscopy (LIBS) instrument on board the rover. This instrument determines the elemental composition of materials by exposing them to intense laser pulses, with each element emitting a characteristic set of wavelengths of light when in a plasma state.

Aditya-L1: India’s First Mission to the Sun

Hot on the heels of this lunar success, ISRO has announced its first mission to the sun, slated to launch on September 2. The mission, named Aditya-L1 (meaning ‘sun’ in Sanskrit), will be carried by a four-stage rocket from Sriharikota island on India’s east coast. The spacecraft will be placed in a halo orbit around the sun-Earth system’s Lagrangian point 1 (L1), a region in space where the gravity of the sun and the Earth balance each other out.

The main objective of the Aditya-L1 mission is to study solar winds, which can influence astronauts and technology. The spacecraft carries seven payloads to observe various layers of the sun, including the photosphere, chromosphere, and the corona. Data from these observations will provide critical insights into coronal heating, Coronal Mass Ejection, pre-flare and flare activities, and other solar phenomena.

Cost-Effective Space Exploration

What’s remarkable about these two missions is their cost-effectiveness. Combined, the moon and sun missions have cost India just $120 million, a stark contrast to the billions spent by NASA and the European Space Agency on similar missions.


India’s recent advancements in space exploration are a testament to the country’s scientific prowess and determination. The successful landing of Chandrayaan-3 on the moon’s South Pole and the upcoming launch of Aditya-L1 to the sun not only mark significant milestones for India but also contribute to our collective understanding of the universe. The economical execution of these missions further demonstrates that effective space exploration does not always require exorbitant budgets. As we look to the future, it’s exciting to imagine what further discoveries and milestones lay ahead in India’s space journey.
