In preparation for the launch later on Wednesday, the European Space Agency (ESA) announced that the countdown for Isro’s dedicated commercial mission—the Proba-3 spacecraft—marks a “proud milestone in India’s space journey.”
ESA has given NewSpace India Ltd, Isro’s commercial division that launches customer cars, the go-ahead for its most recent launch, a “technology demonstration” mission. The mission’s primary goal is to research the Sun’s outer atmosphere and fly a first-of-its-kind configuration with precision.
Isro stated on Wednesday.
“Liftoff Day is Here. PSLV-C59, showcasing the proven expertise of Isro, is ready to deliver ESA’s PROBA-3 satellites into orbit. This mission, powered by NSIL with Isro’s engineering excellence, reflects the strength of international collaboration,”.
According to an Isro official, the 25-hour countdown, which began at 3:08 p.m. on Tuesday, is proceeding in preparation for the launch from the first launch pad at this spaceport on Wednesday at 4:08 p.m.
“A proud milestone in India’s space journey and a shining example of global partnerships,”.
An update of its most recent mission was released by the space agency.
The Proba-3 (Project for Onboard Autonomy) consists of a double-satellite in which two spacecraft would fly together as one, maintaining precise formation down to a single millimeter to study the sun’s outer atmosphere.
The goal of the mission is to show off the two spacecraft’s precise formation flying.
Isro stated
‘Coronagraph’ and ‘Occulter’.
For the mission, the space agency with its headquarters in Bengaluru is using its well-proven Polar Satellite Launch Vehicle (PSLV).
This is the 26th flight of the XL version and the 61st flight of the PSLV. It is expected to put the 550-kilogram Proba-3 satellites into the desired orbit after roughly eighteen minutes of travel.
In order for Coronagraph to conduct scientific observations of the Sun’s corona or surrounding atmosphere, the two satellites would fly 150 meters apart (as one large satellite structure) in tandem after achieving the initial orbital conditions. This would allow the “Occulter” spacecraft to block out the sun’s solar disk.
