India's space journey has reached another important milestone. The Indian Space Research Organisation (ISRO) has officially partnered with Sweden for the much-awaited Shukrayaan mission. The Memorandum of Understanding (MoU) was signed during Prime Minister Narendra Modi's visit to Gothenburg, Sweden. This is India's first dedicated mission to study Venus, the planet often called Earth's twin sister.
The word Shukrayaan comes from Sanskrit and simply means "Venus Craft." The mission is planned for launch on 29 March 2028 using ISRO's powerful LVM-3 rocket, the same rocket that helped Chandrayaan-3 reach the Moon.
Venus is our closest neighbouring planet and is almost the same size as Earth. But the similarities end there. Venus is extremely hot, with surface temperatures crossing 460 degrees Celsius, hot enough to melt lead. It has thick clouds made of sulphuric acid, very high atmospheric pressure, and absolutely no signs of life.
Scientists have always wondered why two planets, born around the same time and nearly the same size, ended up so different. Shukrayaan aims to find answers by studying Venus's surface, atmosphere, and how the Sun's energy affects it.
The breakthrough agreement came during a bilateral summit in Gothenburg. The agreement was signed between ISRO and Sweden's National Space Agency and was among the key outcomes of the summit, during which India and Sweden elevated their relationship to a strategic partnership. This diplomatic milestone was further anchored by the launch of the India-Sweden Technology and Artificial Intelligence Corridor (SITAC), the Joint Innovation Partnership 2.0, and a shared commitment to double bilateral trade over the next five years.
"Under the space agreement, the Swedish Institute of Space Physics (IRF) will provide a special scientific instrument called the Venusian Neutrals Analyser (VNA). This sensor will be integrated into a larger plasma package named VISWAS (Venus Ionospheric and Solar Wind Particle AnalySer), developed by India's Space Physics Laboratory in Thiruvananthapuram, Kerala. The mission will carry 19 scientific payloads in total, with key international contributions also coming from Russia's Space Research Institute, which is providing the Venus Infrared Atmospheric Gases Linker (VIRAL)," explained space analyst Girish Linganna.
So, what this VNA actually does in simple words. "The Sun constantly releases tiny charged particles into space, which scientists call the solar wind. When these particles strike Venus, they push out gas particles from its upper atmosphere. The VNA will carefully measure these escaping neutral particles. By studying them, scientists can understand how Venus has slowly lost its atmosphere over millions of years. This is very important because it can give clues about Earth's own future and how planets change over time," added Linganna.
The friendship between India and Sweden in space science is not new. It began back in the 1980s and has only grown stronger. Sweden had also contributed instruments to India's earlier Chandrayaan missions. Speaking at the joint press conference along with PM Modi and European Commission President Ursula von der Leyen, Swedish Prime Minister Ulf Kristersson said Sweden is proud to be on its way to Venus together with India.
The Venus Orbiter Mission was approved by the Union Cabinet in September 2024 with a budget of around ₹1,236 crore, which is considered very affordable compared to similar missions by other countries. NASA spends much more on similar projects.
Following the successful completion of its Preliminary Design Review in April 2026, the spacecraft is now on track to launch on 29 March 2028. After a 112-day journey, it will enter a specialised elliptical orbit ranging from 500 km at its closest point to 60,000 km at its farthest point above the Venusian surface on July 19, 2028, positioning its instruments perfectly to capture data from varying altitudes.
For Indians, this mission carries deep meaning. It shows that India is no longer just a participant in global space activities but a trusted leader. Countries like Sweden, France, Germany, and Russia are eager to collaborate with ISRO because of its proven track record with Chandrayaan-3's historic Moon landing and the cost-effective Mangalyaan Mars mission. Such partnerships bring in new technology, shared expertise, and lower mission costs.
The Shukrayaan mission also opens fresh opportunities in research, engineering, and innovation.
