1. Vikram-1, country’s first private orbital-class rocket, successfully places tech payloads, postcards into orbit
India achieved a major milestone in its space journey on Saturday (July 18, 2026) as Vikram-1, the country’s first privately developed orbital rocket, successfully placed multiple technology demonstration payloads and postcards into a low earth orbit. Dubbed ‘Mission Aagaman’ (meaning arrival), the mission marks India’s entry into an elite group of nations with private orbital launch capability, making it only the third country in the world to achieve the feat through a privately developed launch vehicle. Skyroot’s Vikram-1, carrying technology demonstration payloads and postcards, lifted off from the Satish Dhawan Space Centre in Sriharikota at the rescheduled time of 12:05 p.m. The launch was witnessed by Skyroot founders Mr Pawan Kumar Chandana and Mr Naga Bharath Daka, both former ISRO scientists, who were present at the agency’s Mission Control Center (MCC) along with ISRO Chairman DR V. Narayanan. On its maiden voyage, the four-stage, seven-storey-tall rocket lifted off at 12:05 pm amid cloudy skies from the first launch pad, leaving behind thick clouds of orange smoke. The lift-off marked a new era for the spaceport. With the launch, Skyroot achieved its first successful orbital mission using the Vikram-1 launch vehicle, marking a major step beyond the suborbital flight of Vikram-S in 2022. After its ascent, the rocket deployed its primary payloads one after another into a 450-km low Earth orbit.
Skyroot Aerospace said the engineering data gathered during the test flight will now be studied to verify the rocket’s guidance and navigation systems and help improve future commercial satellite missions. The mission also confirmed the performance of the rocket’s all-carbon composite structure and 3D-printed engines under actual flight conditions, technologies that the company says are industry-first innovations. Among the payloads carried aboard Vikram-1 was Embrace, a mission by Cosmoserve Space designed to demonstrate robotic arms that could one day be used to remove space debris in orbit. The rocket also deployed Solaras, a compact satellite developed by Grahaa Space to test new capabilities in low Earth orbit (LEO). Skyroot Aerospace’s in-house experimental satellite, SCOPE, was also part of the mission. According to the company, the payload was developed to evaluate space technologies that could be used in future missions.

2. IIT-G develops low-cost device to detect toxic metals, bacteria in water
Researchers at IIT Guwahati have developed a portable optical sensing device that can quickly detect toxic metals, fluoride and bacteria in water samples, offering a low-cost tool for on-site water-quality checks in rural areas and places without easy access to laboratories. Named E-Eye, the device has detected arsenic, lead, iron, chromium, fluoride and Escherichia coli bacteria during laboratory tests, the institute said. The estimated cost of the device is about Rs 3,500, with each sample test costing around Rs 2. The device uses a chemical reaction that produces a coloured compound. The intensity of the colour changes according to the concentration of the contaminant. E-Eye analyses the colour through optical sensing, converts the reading into digital data and displays the concentration of the toxicant. According to the researchers, the portable system can be deployed directly at water sources, unlike conventional testing equipment that generally requires samples to be taken to laboratories. It can also wirelessly transmit test results to water-treatment facilities. The team said E-Eye’s results were comparable with those obtained through standard UV-Visible and Atomic Absorption spectrophotometers. More than 2,700 samples have been tested using the device, it added. The researchers said the device could support water-quality monitoring under the Centre’s Jal Jeevan Mission, which seeks to provide tap water to rural households while ensuring that the water supplied is safe. Apart from drinking water, E-Eye can be used to test environmental and biological samples, vegetables, food products, tea, herbal products, soil and milk, the institute said. It may also help industries monitor liquid effluents containing heavy metals, bacteria and odour-causing compounds. The researchers have set up ENVIONIX Labs Pvt Ltd to commercialise the technology and are exploring an industry partnership for its transfer. They are also working to integrate solar panels and cloud connectivity into the device for remote monitoring and data management.
