BENGALURU: India’s Venus Orbiter Mission (VOM), which can carry 19 scientific devices or payloads, together with a number of worldwide ones, is tentatively scheduled to be launched on March 29, 2028, onboard Isro’s LVM-3 rocket and arrive at its ultimate orbit round Venus 112 days later.
The VOM will discover the planet’s ambiance, floor, and its interplay with the Solar, Isro mentioned Tuesday, including that 16 Indian payloads, two worldwide collaborative payloads, and one worldwide payload have been beneficial by the Consultants Overview Committee.
“Key scientific aims embrace analyzing mud within the Venusian ambiance, mapping its floor topography in excessive decision, finding out the photo voltaic X-ray spectrum close to Venus, analysing Venusian airglow, and investigating sub-surface traits. Moreover, the mission will function a know-how demonstration for Isro, testing aerobraking and thermal administration methods within the harsh Venusian setting,” Isro mentioned.
Stating that the LVM-3 will place the spacecraft in an Elliptical Parking Orbit (EPO) of 170km x 36,000 km, Isro mentioned it should have 21.5° inclination and an Argument of Perigee (AOP) — which defines the trail of the spacecraft to the ultimate vacation spot — of 178°.
“After the cruise section, Venus Orbit Injection (VOI) will probably be at 500km x 60,000km. Aerobraking will probably be employed for over a interval of 6 to eight months from VOI to attain the specified low altitude Science Orbit of 200km x 600km with an inclination of round 90º, to hold out proposed science research for a interval of 5 years,” Isro mentioned.
This inclined orbit will present a superb alternative for the primary time to probe the floor and ambiance with excessive unprecedented spatial and temporal decision and in-situ commentary of the ionosphere.
“As soon as it reaches there, the science information, to be obtained from the devices, will probably be obtained, processed and archived on the Indian House Science Information Heart (ISSDC) for dissemination and use by the scientific group in India and overseas,” Isro added.
Among the many 19 payloads, the VIRAL (Venus InfraRed Atmospheric gases Linker) instrument developed by Russia is the worldwide payload. The 2 collaborative payloads are the Venus Ionospheric and Photo voltaic Wind particle AnalySer (VISWAS), which will probably be developed by Isro’s House Physics Lab at VSSC and a Swedish institute, and the Radio Anatomy of Venus Ionosphere (RAVI), being developed by an Indian group with German collaboration.
