Aditya L-1, Gaganyaan: Mission to Moon

India’s feat of landing Chandrayaan-3, its third lunar spacecraft, is not the culmination but the commencement of an extraordinary journey within the realm of space exploration. Echoing the sentiments expressed by Prime Minister Narendra Modi, the Director of the Indian Space Research Organisation (ISRO), S Somanath, highlighted that India’s “golden era” in the space domain has just begun. As Chandrayaan-3 takes its triumphant place, ISRO is steering multiple high-profile projects poised for the upcoming months. This remarkable mission has solidified India’s stature as a notable contender in the global space arena.

Somanath aptly stated, “The mission of reaching the Moon and achieving a gentle landing is a formidable task. Such a feat is demanding even for nations equipped with advanced technologies. However, India has successfully accomplished this in just two missions. The first attempt was close, and now we have accomplished it with precision.” This remarkable achievement is anticipated to imbue ISRO with the confidence to venture further into the cosmos. The next quarter will see ISRO engrossed in a series of missions.

Embarking on the Sun with Aditya L-1

Amid the exciting trajectory of ISRO’s ventures, the Aditya-L1 project looms prominently. Somanath revealed, “Following Chandrayaan-3, we are gearing up for the Aditya-L1 mission, India’s inaugural sun-oriented endeavor.” The mission has progressed swiftly, with the integrated satellite already positioned at Sriharikota. The forthcoming days will witness the integration of the rocket, setting the stage for a potential launch in early September.

Aditya-L1 represents India’s maiden dedicated scientific exploration of the sun. Initially conceived as Aditya-1, with a satellite weighing 400 kg and the Visible Emission Line Coronagraph VELC payload, it was designed for an 800 km low earth orbit. However, recognizing the advantages of a satellite in the halo orbit around the first Lagrangian Point (L1) of the sun-earth system, the mission was renamed Aditya-L1. This strategic orbit offers continuous sun observation without hindrance from occultation or eclipses.

ISRO’s scientific experts have fashioned the instruments of Aditya-L1 to scrutinize the solar atmosphere, specifically the chromosphere and corona. The in-situ instruments will gather data from the local environment at L1.

Pioneering Gaganyaan’s Abortion Mission Demonstration

ISRO has further unveiled its plans for Gaganyaan, India’s pioneering human spaceflight mission. The demonstration of the abort mission for Gaganyaan is expected in the final week of September or early October. This mission aims to showcase human spaceflight capability by launching a crew of three to a 400 km orbit for a three-day venture and safely returning them to Earth, touching down in Indian sea waters.

ISRO’s roadmap for Gaganyaan integrates a strategic blend of in-house expertise, Indian industry experience, academic acumen, and cutting-edge technologies from international partners. The multifaceted endeavor entails critical technology development encompassing human-rated launch vehicles, life support systems, crew emergency provisions, and comprehensive training, recovery, and rehabilitation strategies.

As ISRO unfurls its manifold endeavors, India’s presence in the cosmos deepens. With Chandrayaan-3 as the inaugural note, Isro continues its journey as a visionary pioneer in space exploration.
