Context / Background

Planetary parades, where multiple planets align and are visible together in the night sky, are notable astronomical events. While it is common to see two or three planets around sunset, larger groupings are less frequent and can be captivating for both amateur astronomers and casual sky gazers. This specific parade of Mercury, Venus, and Jupiter will occur during a broader planetary event throughout June 2026, which includes the close pairing of Venus and Jupiter just a few days earlier on June 9.

Key Details

The parade will present Mercury, Venus, and Jupiter aligned in a slanted line along the ecliptic, creating a visual treat for those who catch it at the right time. The optimal viewing window is approximately 30 minutes after local sunset, during which the alignment will last around 30 to 45 minutes before Mercury and Jupiter set below the horizon.

For anyone interested in viewing this planetary spectacle, they should aim for a clear, unobstructed view of the horizon, especially towards the western sky. Bright twilight may make the fainter planets more challenging to spot, so timing is crucial.

Venus will be the easiest to distinguish as it is the brightest planet, visible first in the twilight sky. After spotting Venus, observers can look down and slightly to the right to locate Mercury and Jupiter.

In terms of viewing equipment, the alignment can be seen with the naked eye, but using a wide-angle lens or a smartphone for photography may enhance the experience.

Impact

This event is particularly significant for sky watchers in many regions, as it presents an excellent opportunity for educational outreach, particularly within the context of astronomy clubs and schools. The visibility of Venus as a prominent evening object will likely attract both seasoned astronomers and casual observers.

The increased visibility of Mercury later in June, following this parade, will sustain interest in astronomy during the month, potentially leading to more public engagement with sky watching. For regions in India, where both urban and rural areas may witness varying levels of light pollution, clear viewing conditions will be essential. Those in cities may need to seek elevated or dark spaces to get the best view of the parade.

What’s Next

In the days leading up to the parade, discussions and excitement about the planetary alignments will likely grow, especially as the Venus-Jupiter close pairing on June 9 draws attention. As June progresses, sky watchers will also notice Mercury gaining prominence in the early evening sky through June 22, making this an excellent month for astronomical observation. As always with celestial events, preparation and awareness of timing and location will enhance the viewing experience for all.

How a 360-kg experiment built in Bengaluru in the 1970s became India’s first step into orbit.

When India launched Aryabhata on April 19, 1975, it was more than a technological milestone — it was a statement of intent. After years of groundwork laid by Vikram Sarabhai and his team, ISRO was finally ready to enter space not just as a learner, but as a creator.

Named after the 5th-century Indian mathematician-astronomer Aryabhata, the satellite symbolized the union of India’s scientific past and its technological future. It was designed and built entirely by Indian scientists at the ISRO Satellite Centre (now UR Rao Satellite Centre) in Bengaluru. The Soviet Union provided the launch vehicle — a Kosmos-3M rocket — which lifted off from the Kapustin Yar launch site in Russia.

At just 360 kilograms, Aryabhata carried five scientific experiments focused on X-ray astronomy, solar physics, and aeronomy. Its mission was to collect data about the upper atmosphere and solar radiation, helping Indian scientists understand conditions that would affect future communication and weather satellites.

Despite a power failure after just four days, Aryabhata transmitted valuable data during its brief operational period. More importantly, it proved that India could design, assemble, and test a complex satellite system using indigenous talent — an extraordinary achievement for a developing nation at the time.

The satellite’s construction itself tells a story of innovation under constraint. Components were fabricated by hand, and testing facilities were improvised with limited resources. Yet, every challenge became a lesson that shaped ISRO’s culture of frugal engineering — achieving reliability and performance at minimal cost.

Aryabhata also marked the beginning of India’s international collaborations in space. While the Soviets provided the launch, the satellite’s core was purely Indian. The experience gave ISRO the confidence to later develop its own launch vehicles — the SLV and eventually the PSLV, which would make India a leader in cost-efficient satellite deployment.

The mission’s legacy extends beyond science. Aryabhata’s geometric shape — a 26-sided polyhedron covered with solar cells — became an icon of national pride. India even commemorated it on a postage stamp, and for many citizens, it was their first glimpse of the country’s cosmic ambitions.

The Spacecraft mainframe remained active till March 1981. The satellite entered Earth’s atmosphere on 10 February 1992 due to orbital decay.   It laid the foundation for hundreds of missions that followed — from remote-sensing and weather satellites to interplanetary explorers like Mangalyaan and Chandrayaan-3.

As India celebrates World Space Week, Aryabhata remains a reminder that even the smallest first step, built with courage and ingenuity, can set a nation on a trajectory toward greatness.

How a modest initiative in the 1960s grew into one of the world’s most respected space agencies.

In 1962, India took its first step towards space exploration with the formation of the Indian National Committee for Space Research (INCOSPAR). At a time when the country was still finding its footing after independence, few could have imagined that this small committee would lay the foundation of the Indian Space Research Organisation (ISRO), one of the world’s leading space agencies today.

The visionary behind this bold move was Dr. Vikram Sarabhai, often called the father of the Indian space program. Sarabhai believed that space science should not be a luxury reserved for advanced nations but a tool for solving everyday challenges in a developing country like India. He famously said, “We do not have the fantasy of competing with the economically advanced nations in the exploration of the moon or the planets… But we are convinced that if we are to play a meaningful role nationally, and in the community of nations, we must be second to none in the application of advanced technologies to the real problems of man and society.”

With this philosophy, INCOSPAR set up the Thumba Equatorial Rocket Launching Station (TERLS) in Kerala in 1963. From this humble facility, India launched its first sounding rocket, marking the beginning of its tryst with space. These early missions were not about prestige but about learning and experimentation. Scientists often transported rocket parts on bicycles and bullock carts—an image that continues to symbolize ISRO’s spirit of innovation and frugality.

By 1969, INCOSPAR had evolved into ISRO, an organization dedicated to harnessing space technology for national development. The early years were marked by collaboration with international agencies, particularly NASA, which helped India train scientists and acquire technical know-how. Yet, ISRO was determined to chart its own path.

The 1970s saw India launch Aryabhata (1975), its first satellite, developed in India and launched by the Soviet Union. This was a turning point—it showed that India was capable of not just dreaming big but also executing those dreams. From there, ISRO steadily expanded its capabilities, laying the groundwork for its now-famous launch vehicles and satellite programs.

What makes ISRO’s origin story remarkable is not just its scientific achievements but the philosophy behind its creation. Instead of chasing prestige missions, Sarabhai and his successors focused on using satellites for weather forecasting, communication, education, and rural development. This people-first approach gave ISRO a unique identity in the global space community.

Today, as India celebrates its presence on the Moon with Chandrayaan-3 and eyes human spaceflight with Gaganyaan, it’s important to remember the modest beginnings that shaped ISRO’s ethos. From bicycle rides in Kerala to rocket launches at Sriharikota, the journey embodies resilience, vision, and the belief that science should serve society.
