On Sunday, July 30, 2023, the Indian Space Research Organisation successfully launched its proven Polar Satellite Launch Vehicle rocket carrying seven Singapore satellites from the Satish Dhawan Space Centre in Sriharikota and placed them into intended orbits.
India's PSLV-C9 blasted off into space, carrying ten satellites including the country's latest remote sensing satellite CARTOSAT-2A, from Indian Space Research Ogranisation's Satish Dhawan Space Centre in Sriharikota on Monday.Scientists cheered as the Polar Satellite Launch Vehicle, in its thirteenth flight, soared into the clear sky in a perfect lift off at 9.23 am from the second launch pad.Besides the 690 kg CARTOSAT-2A, the PSLV is also carrying Indian Mini Satellite.
The successful launch of Aditya-L1 - the country's maiden mission to study the Sun - is expected to garner increased investor interest in the Indian space sector and trigger more funding for private players. Several private sector players, including Larsen & Toubro (L&T), MTAR Technologies, and Ananth Technologies, have played a pivotal role in the Indian Space Research Organisation's (Isro's) solar observatory mission. Aditya-L1 on Saturday set off on a 125-day journey on a PSLV-C57 rocket, in its attempt to study various elements relating to the nearest star from the halo orbit around Lagrange point 1 (L1) of the Sun-Earth system, which is about 1.5 million km from Earth.
The Polar Satellite Launch Vehicle PSLV-C15 carrying five payloads, including India's remote sensing satellite Cartosat-2B, successfully lifted off from the spaceport in Sriharikota on Monday.
For carrying the 360-kg Italian satellite, meant for astronomical studies, Indian Space Department's commercial wing Antrix Corporation would receive a fee from the Italian space agency.
'With India's growing capabilities in the space sector, this creates promising opportunities for enhanced collaboration and market access.'
Once deployed and operational, it will be used to support the satellite imagery requirements of various agencies within the government of Singapore.
Weighing 320 tonne at lift-off, the vehicle used larger strap-on motors to achieve higher payload capability.
The Indian Space Research Organisation (ISRO) on Monday successfully launched its maiden X-Ray Polarimeter Satellite that would offer several insights into celestial objects like black holes.
The successful launch of the maiden solar mission of the Indian Space Research Organisation came on the heels of the historic lunar landing mission - Chandrayaan-3.
Indian Space Research Organisation (ISRO) will conduct three more test vehicle missions under the ambitious Gaganyaan programme after the maiden TV-D1 test flight, which is scheduled on October 21, the space agency's chairman S Somanath has said.
Days after landing on the Moon, India will aim for the Sun on Saturday with its maiden solar expedition, as ISRO's trusted PSLV will carry the Aditya L1 mission on a 125-day voyage to the Sun.
'When a Project Director is appointed, the whole organization -- including the Chairman ISRO -- works for his success. It is a lesson that has been of abiding value all through the other projects I have worked on,' recalls the late President, one of the earliest pioneers at ISRO.
According to the Indian Situational Space Awareness Report for 2023, the nominal lift-off of the Launch Vehicle Mark-3, carrying the Chandrayaan-3 spacecraft, had to be delayed by four seconds based on the Collision on Launch Avoidance analysis.
The Aditya-L1 mission carries seven scientific payloads to carry out the study.
ISRO said on Saturday the Aditya-L1 spacecraft has travelled beyond a distance of 9.2 lakh km from Earth, successfully escaping the sphere of Earth's influence.
Aditya -- the name in Sanskrit refers to the Sun -- is a coronagraphy spacecraft manufactured at the U R Rao Satellite Centre in Bengaluru to study the solar atmosphere.
Preparations are in the final stages by the Chennai-headquartered space-tech startup Agnikul Cosmos for the maiden launch of India's first-ever private launchpad and the second rocket launch by a private sector player.
