From deep space missions to critical cybersecurity updates and advancements in solar research, a variety of scientific and technological developments are shaping our understanding of the universe and our world.
Eyes on Earth and Beyond: The NISAR Mission
The NISAR (NASA-ISRO Synthetic Aperture Radar) mission is a collaborative Earth observation satellite developed jointly by NASA and ISRO. This ambitious project is set for launch on the GSLV-F16 rocket, destined for a 734 km sun-synchronous orbit.
Once operational, NISAR will scan the entire globe every 12 days, delivering highly detailed images of Earth’s surface. It stands out as the first satellite ever to observe our planet in two distinct frequencies: NASA’s L-band and ISRO’s S-band, offering unparalleled insights into Earth’s dynamic systems.
Unveiling the Sun’s Dynamic Chromosphere
The Sun’s chromosphere is a vital and highly dynamic region, positioned between the visible surface (photosphere) and the outermost atmosphere (corona). It is within this reddish layer that powerful solar phenomena like flares, hot plasma jets, and intense energy fluxes originate.
To better understand this region, NASA is deploying a suborbital sounding rocket experiment featuring the Solar EruptioN Integral Field Spectrograph (SNIFS). This instrument is designed to provide 3D spectroscopic data, capturing a full spectrum for each pixel and targeting the hydrogen Lyman-α spectral line, a crucial diagnostic for chromospheric conditions. The mission, however, is a short one, lasting under ten minutes, not several years as an orbital satellite.
India’s Iconic MiG-21s Set for Retirement
After six decades of service, the Indian Air Force (IAF) is preparing to retire its remaining fleet of Russian-origin MiG-21 fighter jets. The last of these legendary aircraft will be ceremonially decommissioned on September 19 at the Chandigarh airbase.
Currently, only two squadrons of the upgraded MiG-21 Bisons remain operational. The phasing out of these aircraft, initially planned for 2022, was delayed as India awaited the induction of new indigenous Light Combat Aircraft Tejas, which will take their place.
Understanding the ‘Bleeding Eye’ Virus: Marburg
The Marburg virus, often referred to as the ‘bleeding eye’ virus, is one of the most severe diseases capable of infecting humans. Belonging to the filovirus family, like Ebola, it causes clinically identical infections with high fatality rates, ranging from 24% to 88% in previous outbreaks.
First identified in Marburg, Germany, in 1967, subsequent outbreaks have predominantly occurred across Africa. The World Health Organization lists Marburg as a significant public health threat, for which no effective treatments or vaccinations currently exist.
The Powerful Products of Volcanic Eruptions
Volcanic eruptions are dramatic geological events that release a variety of materials from Earth’s interior. These include liquid rock, known as magma underground and lava once it erupts, along with ash and dust.
Additionally, volcanoes emit various gases such as sulphur compounds, nitrogen compounds, and trace amounts of chlorine, hydrogen, and argon. Pyroclastic debris and volcanic bombs are also common products of these powerful natural occurrences. It is important to note that helium is not a product of volcanic eruptions.
Europa: A Promising Hunt for Life Beyond Earth
Europa, one of Jupiter’s moons, is widely considered a leading candidate in the search for extraterrestrial life within our solar system. This is primarily due to strong evidence suggesting it harbors a subsurface ocean of liquid water and displays signs of active geology.
Recent observations by the James Webb Space Telescope have further bolstered this prospect, detecting carbon dioxide and crystalline water ice on Europa’s surface. These findings, particularly in regions like Tara Regio, indicate that material from the moon’s subsurface ocean is reaching the surface, suggesting conditions potentially conducive to life.
Cryptocurrency Exchange CoinDCX Hit by Major Hack
Mumbai-based cryptocurrency exchange CoinDCX recently experienced a significant security breach. On July 19, 2025, the platform lost US $44.2 million from an internal operational wallet due to a hack, which was discovered 17 hours later by a blockchain investigator.
