The Indian Space Research Organisation (ISRO) is developing Venus Mission the VOM (Venus Orbiter Mission) at a cost of Rs 1,236 crore. It is going to investigate the planet’s atmosphere, surface, and interaction with the Sun.
The space agency ISRO stated on Tuesday about Venus Mission that key scientific objectives include researching dust in the Venusian atmosphere, mapping its surface topography in high resolution, studying the solar X-ray spectrum near Venus, analyzing Venusian airglow, and investigating subsurface properties.
The incredibly ambitious Venus Mission (VOM) of India is scheduled to launch on March 28, 2028, with 19 payloads. These will comprise one international payload that has been suggested by the Experts Review Committee, as well as two collaboration scientific instruments from India and outside. The goal will be completed in five years.

The Indian Space Research Organization (ISRO) is spending Rs 1,236 crore developing the Venus Mission (VOM), which will investigate the planet’s surface, atmosphere, and relationship with the Sun. According to the space agency on Tuesday, major scientific goals include assessing dust in the Venusian atmosphere, mapping the planet’s surface topography in high resolution, evaluating Venusian airglow, and researching subsurface features.
Additionally, along similar lines to Chandrayaan-3, the mission will aid in technological demonstration for ISRO, testing aerobraking and thermal management techniques in the hostile Venusian environment.
The limited and narrow spatial coverage of the Venus missions (conducted by other countries), thus far has been either in the equatorial belt or in the South Polar area. For this reason, creating worldwide maps of many phenomena such as winds, waves, and chemical abundances is challenging.

According to ISRO, Venus Mission would offer consistent coverage of Venus, creating a special worldwide dataset for upcoming scientific missions. The space agency estimates that the spacecraft will arrive to Earth’s twin planet in more than 112 days, with a tentative arrival date of July 19, 2028.
The space agency disclosed that the spacecraft will be placed near Venus using its reliable Launch Vehicle Mark-3 (LVM-3) rocket. In a statement, ISRO stated that LVM-3 has been selected as the potential launch vehicle. This will put the spacecraft in an Elliptical Parking Orbit (EPO) measuring 170 km by 36,000 km, with an inclination of 21.5° and an Argument of Perigee (AOP) of 178°.
To reach the required low altitude after the cruise phase the spacecraft’s flight aerobraking will be used for a duration of six to eight months. A number of demonstrations to explore Venus will be conducted during this time. Scientists think that these studies will offer a great chance to investigate Venus’s surface and atmosphere for the first time.
ISRO will work on the creation of scientific equipment along with nations like Germany, Sweden, France, Russia, and Finland. Venus Mission and three other bold plans to establish the nation as a space powerhouse were authorized by the Cabinet in mid-September.
Chandrayaan-4 will boost self-reliance :
In order to investigate if the Moon is habitable, India will need to return samples from the lunar surface. With a projected cost of ₹2,104.06 crore, ISRO’s Chandrayaan-4 mission is slated to launch in 2029 and consist of five modules: the Ascender Module (AM), Descender Module (DM), Re-entry Module (RM), Transfer Module (TM), and Propulsion Module (PM). Two stacks of these will be launched on two different LVM3 launch vehicles.
“After landing, samples weighing two to three kilograms will be collected from the area surrounding the landing site by a robotic arm positioned on the DM, also known as the Surface Sampling Robot, and transferred to a container on the AM. Additionally, subsurface samples will be collected by a drilling mechanism and moved to a different container in the AM. Sample-carrying containers will be sealed throughout transit to Earth to avoid contamination and leaks. Video cameras will be used to monitor several stages of the sample collecting process, ISRO said in a statement on Tuesday.

The purpose is to use all important technologies developed in the nation while promoting self-reliance. It is anticipated that Indian industry will be essential to achieving the goal, fostering skill development, generating large job opportunities, and advancing technology. The space agency stated that “Chandrayaan-4 will pave the way for India’s future manned missions, lunar sample return, and scientific analysis.”
