The PSLV-C61/EOS-09 is scheduled to instrumentality disconnected precisely astatine 5:59 americium this Sunday.

Equipped with a C-band synthetic aperture radar, the imaging outer volition beryllium injected into a Sun-synchronous orbit, from wherever it volition supply high-resolution images of the Earth’s aboveground nether all-weather conditions, time oregon night. The information volition beryllium important for sectors specified arsenic agriculture, catastrophe response, municipality planning, and nationalist security. The erstwhile EOS-08 was launched aboard the 3rd developmental formation of the SSLV past August.

This is 1 of respective cardinal missions ISRO has lined up implicit the adjacent 2 months. Among them is the Test Vehicle (TV-D2) mission, designed to simulate an abort script and show the Gaganyaan unit flight system. The ngo volition besides see oversea betterment operations for the unit module to validate procedures planned for India’s archetypal quality spaceflight.

Then determination is the much-awaited motorboat of the NISAR outer – a cardinal collaboration betwixt ISRO and NASA. The outer volition beryllium launched aboard the GSLV-F16 to survey Earth’s ecosystems and earthy hazards utilizing dual-frequency radar data, combining NASA’s L-band payloads with ISRO’s S-band contributions.

ISRO’s commercialized limb – NewSpace India Limited (NSIL) – has besides precocious signed a declaration with M/s HAL (lead spouse of the HAL and L&T consortium) for the end-to-end manufacturing of 5 Polar Satellite Launch Vehicles (PSLV). The archetypal afloat Indian industry-manufactured PSLV is expected to beryllium launched successful the 2nd fractional of this year, Union Minister of State for Space Dr Jitendra Singh had earlier informed Parliament.
