- ISRO Proba 3 Launch Live: The space mission in collaboration with the European Space Agency will study the Corona, the Sun's outer atmosphere
ISRO Proba 3 Launch Live: ISRO'S commercial space mission for the European Space Agency (ESA), the Proba-3 spacecraft was launched today at 4:04 pm, in a showcase of India's role in global space innovation and collaboration....Read More
The 550-kg Proba 3 mission will be conducted from the spaceport at Sriharikota, Andhra Pradesh and will be managed by ISRO's commercial arm, NewSpace India Ltd.
The mission was initially supposed to be launched on December 4, at 4:08 pm but was re-scheduled minutes before lift-off by the ESA after an anomaly was detected in the satellite propulsion system.
The Proba (Project for Onboard Anatomy) is also named after the latin word which means “let's try”. It will be the first space initiative to demonstrate flying in a precise formation down to a single millimetre to study the Sun's outer atmosphere - the Corona.
Key points:
- Proba 3 will consist of two satellites - Coronagraph (310kgs) and Occulter (240kgs), which will fly together as one, 150 metres apart from each other.
- The mission will provide key insights on the Corona, which according to the ESA, is hotter than the Sun and determines space weather as well.
- The instruments on both the satellites will take close to six hours at a time to reach the solar rim and will commence a 19-hour orbit around the Earth.
- The 44.5 metre tall rocket is supposed to take 18 minutes to reach its desired orbit.

ISRO Launch Live: Proba-3 launch marks new age in space exploration
ISRO Launch Live: The launch of Proba-3, a collaboration between ISRO and the ESA will open up new doors for space and solar exploration.
The shadow cast by the Occulter satellite allows the Coronagraph to observe solar phenomena while blocking out the light from the Sun itself, which is it has been dubbed an “artificial eclipse” maker.
"For six hours at a time, it will be able to see the Sun's faint atmosphere, the corona, in the hard-to-observe region between the Sun's edge and 1.4 million kilometres from its surface," the ESA stated.
The project will help scientists answer important queries, including why the corona is so much hotter than the Sun itself, and how the Sun's energy output changes over time.

ISRO Launch Live: ESA opted for ISRO collaboration due to proven cost efficiency and performance
ISRO Launch Live: The European Space Agency collaborated with ISRO for the successful launch of the Proba-3 rocket, due to the Indian space agency's cost efficiency and performance.
The project which was in development with the ESA for over a decade cost about 200 million euros and received support from over 40 European companies, including SENER Aerospace, Redwire Space, and Airbus Defence and Space.
The ESA also struggled due to continuous setbacks and delays in their launch programme, until it achieved orbital entry today

ISRO Launch Live: Proba engineer says Corona has been ‘poorly investigated’ till now
ISRO Launch Live: Proba-3, which was collaboratively launched using the PSLV-C59 vehicle, by the European Space Agency and ISRO, successfully entered orbit today.
The mission will provide key insights into solar phenomena and will study space weather through its observation of the Sun's outer rim - the Corona.
"The corona of the sun has been very poorly investigated. One of the things we really want to understand is how do coronal mass ejections or solar wind originate in this area," Proba-3 Systems Engineer Esther Bastida Pertegaz said in a pre-recorded video.

ISRO Launch Live: ISRO chairman congratulates team, wishes for mission goals to be successful
ISRO Launch Live: ISRO chairman S Somnath addressed the members of the PSLV and Proba teams from India and the European Space Agency after Proba-3 successfully achieved orbit.
The chairman said, “The PSLV-C59 Proba-3 launch has been accomplished. The spacecraft has been placed in the right orbit, a highly elliptical orbit of around 600 km at perigee (closest point to earth) and 60,000 km apogee (the farthest point from earth).”
He also congratulated the PSLV and Proba teams and wished them luck on achieving their mission goals.
