Patha Bhavan old boy part of ISRO's Earth observation satellite project
2
Kolkata: Subhradip Ghosh, a scientist from Kolkata who is currently with the Indian Space Research Organisation (
ISRO
), has played a crucial role in the launch of the GSLV-F16 rocket that was launched from Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh, on July 30.
The former Patha Bhavan student has been part of over 25 ISRO missions, including Chandrayaan-2, Chandrayaan-3, Aditya-L1, and SPADEX. The son of a retired bank manager, he completed his chemical engineering from Heritage Institute of Technology and then pursued his M.Tech from IIT Guwahati. Although he initially considered going abroad to pursue his research career, he joined ISRO.
The rocket carries on board the NASA-ISRO Synthetic Aperture Radar (NISAR) that will study land and ice deformation, land ecosystems, and oceanic regions in areas of common interest to the US and Indian science communities.
NISAR is currently in the critical 90-day commissioning phase during which scientists will carry out rigorous checks, calibrations, and orbital adjustments to prepare the satellite for full-scale Earth observation.
The satellite aims to measure Earth's changing ecosystems and dynamic surfaces, including melting ice sheets and vegetation changes, providing critical data on biomass, sea-level rise, and natural hazards.

Ghosh, who has been in ISRO for six years, was instrumental in overseeing and managing liquid propulsion system of the 52-meter-tall, three-stage rocket. His responsibilities included the precise handling of its hydrazine-based propellant and nitrogen tetroxide oxidizer.
The liquid stage, which utilizes solid, liquid, and cryogenic fuels, demanded extreme precision; even the smallest deviation could compromise the mission.
Ensuring accurate propellant insertion and continuous 24x7 monitoring post-insertion were paramount, with no room for error.
"I am really thankful to be a part of this costliest Earth observation satellite. Before this launch, the entire team worked so hard as the satellite will play a vital role in mapping Earth and providing data that can help from agricultural development to prediction for natural calamities and several other major things," said Ghosh, who has encountered both successes and failures during his stint with ISRO.
Chandrayaan-2 in which landerVikram failed to achieve a soft landing on the Moon due to a deviation from its planned trajectory during the descent phase, was his second project. "All these are the learning experiences in my journey as a scientist."
While his contributions were largely behind the scenes, sources within the ISRO launch crew deemed them "indispensable." Ghosh's teachers, friends, and family felt proud of his achievement and the vital role that he is playing as a part of such prestigious projects. Pradip Agarwal, CEO, Heritage Group of Institutions, said, "Our alumnus Subhradip Ghosh, an ISRO scientist, who did his BTech from this institute, played a crucial role in the prestigious NASA-ISRO Synthetic Aperture Radar Mission.
This achievement will motivate other students as well."

5 common mistakes that attract mosquitoes to you
They may be tiny, but mosquitoes are considered the deadliest animals on Earth, responsible for spreading diseases like malaria, dengue, Zika, and yellow fever. According to the World Mosquito Program, these buzzing bloodsuckers contribute to over one million deaths every year, making it worth understanding what draws them in. Not considering your blood type Some blood types are more attractive to mosquitoes than others — and unfortunately, this isn't something you can control. In a 2022 study , researchers found that different mosquito species show distinct preferences: Type O: Highly attractive to the Asian tiger mosquito ( Aedes albopictus ) Type AB: A favorite of the marsh mosquito ( Anopheles gambiae ) Even more interesting : around 80% of people naturally secrete a substance through their skin that reveals their blood type. If you're a "secretor," you're more likely to get bitten — regardless of your actual blood group. Producing more carbon dioxide Mosquitoes have a strong sense for carbon dioxide, and they can detect it from over 100 feet away. That's bad news if you breathe heavily, talk a lot outdoors, and sleep with your mouth open. Because CO₂ is exhaled through your nose and mouth, mosquitoes are often drawn to your head and face first. That constant buzzing near your ear? Not your imagination. Letting sweat and skin bacteria build up Mosquitoes don't just smell sweat; they analyze it. Your skin produces several chemical cues that they love- lactic acid and ammonia in sweat, bacteria that mix with sweat to form unique body odors, and carboxylic acids, or fatty acids, which one study found in higher concentrations in people most prone to bites. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like They Were So Beautiful Before; Now Look At Them; Number 10 Will Shock You Cash Roadster Undo Overlooking Factors Like Pregnancy and Alcohol Certain conditions can amplify your mosquito appeal. One such is pregnancy. A 2000 study in Africa found that pregnant women attracted twice as many mosquitoes as non-pregnant women. This was linked to increased carbon dioxide output and higher body temperature during late pregnancy. Another is beer. Even a single bottle can make a difference. In one study, participants who drank a liter of beer attracted significantly more mosquitoes than those who drank water. The reason isn't fully understood, but it may be due to alcohol's effect on body chemistry and temperature. Wearing the wrong clothes and eating the wrong foods Clothing and diet also matter. Mosquitoes are visual hunters, and they're drawn more to dark colors like green and black than to lighter shades such as white or gray. As for food, while evidence is still emerging, one study from the University of Wisconsin found that eating bananas increased mosquito contact. Folk wisdom also points to salty, sweet, spicy, or potassium-rich foods as potential culprits, but the banana link is one of the few backed by research.

2 Red Panda cubs born at Himalayan Zoological Park, Bulbuley, after seven years
Two Red Panda cubs were born in the Himalayan Zoological Park (HZP), Bulbuley near Gangtok, after seven years, an official statement said. The cubs were born to parents Lucky(II) and Mirak. This is the pair's first litter together and marks a significant milestone in the park's conservation efforts, it said.

Their successful breeding laid the foundation for a thriving genetic lineage. In 2005, the programme was further strengthened with the inclusion of a wild-origin pair, Lucky and Ram, helping expand and diversify the genetic pool, it said. The statement said that all red pandas born under this programme are tracked through national and international studbooks to ensure healthy genetic variability and global breeding cooperation. Live Events Red pandas typically breed in the winter months between November and January. After a gestation period of around five months, females give birth between June and August, in warm, hidden nests. Remarkably, both Lucky(II) and Mirak were observed participating in nest-building-a rare instance of male involvement. However, cub-rearing remains the mother's responsibility, who teaches the young to climb and forage. Any disturbance by predators or humans can result in the cubs being abandoned at this vulnerable age, said the statement. It said that the cubs will be raised by their parents away from the public eye until they are old enough for viewing. These new cubs will stay with their mother for over a year, reaching full size by 12 months and becoming sexually mature by 18 months. Their health and compatibility will then be assessed as part of future breeding strategies.

ISRO Sets Up Station In Ladakh To Simulate Life On Moon, Mars
Marking a significant leap in India's space exploration efforts, the Indian Space Research Organisation (ISRO) has set up the Himalayan Outpost for Planetary Exploration (HOPE) in Ladakh's Tso Kar Valley. It is a high-altitude, Mars-like environment selected to test life-support systems and technologies for future lunar and Martian missions. The HOPE station, inaugurated on July 31 by ISRO chairman Dr V Narayanan, will be used to test systems for future space missions. The project is led by ISRO's Human Space Flight Centre, along with support from an industry partner and top research institutions. The analogue mission is part of a growing international movement to study how humans might survive and thrive in extra-terrestrial environments by replicating the harsh conditions of other planets on Earth. Why Tso Kar Valley Was Picked For Testing The Tso Kar Valley was chosen for its environmental similarities to Mars, which include high UV radiation, low atmospheric pressure, extreme cold and saline permafrost. The HOPE facility has two connected units. One is an eight-metre wide living space for the crew, while the other is a five-metre utility module housing equipment and support systems. A 10-day trial mission is being held from August 1 to 10, where two crew members will stay inside and take part in various physical, mental and task-based tests. Scientists from institutions like IIT Bombay, IIT Hyderabad, IIST Trivandrum, RGCB Trivandrum and the Institute of Aerospace Medicine in Bengaluru are leading several experiments. They are studying how isolation affects the body and mind, testing health-monitoring tools, and trying out methods for working on planetary surfaces and collecting microbes. The results will help shape safety plans, equipment and systems for future space missions. ISRO On HOPE Mission Calling the HOPE mission 'a rehearsal for the future,' Dr Narayanan said that the initiative aligns with Prime Minister Narendra Modi's vision of expanding private sector participation in India's space programme. Coinciding with the HOPE mission, new research from Ladakh's high-altitude Puga Valley has uncovered clues about the origins of life on Earth. Indian scientists have found that the valley's geothermal springs may mimic early Earth conditions and can preserve organic molecules associated with life's beginnings. A study by the Birbal Sahni Institute of Palaeosciences (BSIP) has found traces of amino acid compounds, fatty acids, formamide and sulphur in calcium carbonate deposits (travertine) from the area. According to lead researcher Dr Amritpal Singh Chaddha, 'The high UV exposure and extreme conditions of the Puga Valley mimic those of early Earth and potentially, ancient Mars.' Published in ACS Earth and Space Chemistry, the study, along with the ongoing HOPE mission, is positioning Ladakh as a key hub for India's growing space and astrobiology efforts.
