In a bold step forward for planetary science, the European Space Agency (ESA) has released a rich dataset from its long-serving Mars Express mission, offering new insights into the Martian atmosphere and reaffirming its commitment to exploring the Red Planet well into the next decade.

The data release includes 71 radio occultation profiles, which are highly valuable for understanding the temperature, pressure, and density of the Martian atmosphere at various altitudes. These profiles were gathered by tracking how radio signals from the spacecraft bend as they pass through the atmosphere — a method that reveals subtle but significant changes in its structure.

The newly released data spans observations taken between October 2022 and April 2023, focusing on the planet’s polar regions and providing seasonal insights. These observations will be especially useful to climate scientists and mission planners preparing for upcoming Mars missions, including those involving human exploration.

In tandem with the data release, ESA announced a major software upgrade for Mars Express. This enhancement dramatically increases the spacecraft’s data handling and communication capacity. The upgrade also introduces new autonomous capabilities, allowing the orbiter to carry out more complex tasks without real-time instructions from Earth.

Mars Express, launched in 2003, has long surpassed its initial mission timeline. Yet, it remains one of ESA’s most valuable assets in orbit around Mars. With this new extension, the mission will now continue through at least 2034, bringing its operational lifetime to over three decades — an extraordinary achievement for an interplanetary mission.

The continued operation of Mars Express is not just symbolic — it plays a critical role in ongoing and future Mars exploration. It provides relay communication support for landers and rovers on the surface, including potential future missions from ESA, NASA, and other space agencies. The orbiter also contributes to monitoring Martian weather and surface changes, crucial for understanding the planet’s long-term evolution.

One of the most exciting aspects of the mission’s extended timeline is the potential to observe rare atmospheric phenomena and surface events over a long temporal baseline. This includes dust storms, seasonal CO₂ ice buildup, and even signs of ancient water flows or volcanic activity.

Updating a 1990s-era satellite felt like digital archaeology—mission operators had to revive Microsoft Windows 3.1, sift through 33-year-old code, and manually calculate the changes before uploading them to the star tracker’s memory.

ESA’s move to publish detailed datasets openly aligns with a growing trend of international scientific collaboration. The 71 newly available radio occultation profiles are expected to be widely used by researchers across the globe, encouraging comparative studies with data from other Mars missions such as NASA’s MAVEN or China’s Tianwen-1.

With the upgraded systems, fresh data, and a green light to operate until 2034, Mars Express continues to live up to its name — delivering fast, accessible science and keeping Europe firmly on the frontline of Martian exploration.

Aryabhata: India’s First Satellite That Sparked a Space Revolution

Launched in 1975, Aryabhata was India’s first satellite — a 360-kg marvel that ignited the nation’s space journey and proved Indian scientists could build for the stars.

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.
