एमिसैट प्रक्षेपित
EMISAT - भारतीय अंतरिक्ष अनुसंधान संगठन (इसरो) ने 1 अप्रैल 2019 को सुबह करीब 9:27 बजे 29 उपग्रहों को अपने विश्‍वसनीय रॉकेट पीएसएलवी-45 के जरिए प्रक्षेपित कर दिया। इस मिशन के तहत इसरो ने एक स्‍वदेशी और 28 विदेशी उपग्रहों को धरती की दो अलग-अलग कक्षा में स्‍थापित किया है। इस अभियान में पहली बार चार स्‍ट्रैपऑन मोटर वाले पीएसएलवी के क्‍यूएल संस्‍करण ने उड़ान भरी थी। इससे पहले इस यान ने दो, छह या फिर बिना स्‍ट्रैपऑन मोटर के ही उड़ान भरी है। इसी अभियान के तहत इसरो ने भारत के एमिसैट (EMISAT) उपग्रह को भी सफलता पूर्वक कक्षा में स्‍थापित कर दिया। यह एक प्राइमरी उपग्रह है जिसका वजन करीब 436 किग्रा है। एमिसैट को इसरो और डीआरडीओ ने मिलकर बनाया है.

BOB बनेगा देश का तीसरा बड़ा बैंक
सार्वजनिक क्षेत्र का बैंक ऑफ बड़ौदा विजया और देना बैंक का खुद में मर्जर कर 1 अप्रैल 2019 को देश का तीसरा सबसे बड़ा बैंक बन जाएगा। गौरतलब है कि सरकार ने इन बैंकों के मर्जर की घोषणा पिछले साल सितंबर महीने में की थी। इसके बाद यह स्टेट बैंक ऑफ इंडिया और एचडीएफसी बैंक के बाद देश का तीसरा बड़ा बैंक बन जाएगा। हाल के ही कुछ वर्षों में यह देश के सरकारी बैंकों का दूसरा सबसे बड़ा विलय है। इसके पहले स्टेट बैंक ऑफ इंडिया (एसबीआई) ने अपने पांच सहयोगी बैंकों का खुद में मर्जर कर लिया था। इनमें स्टेट बैंक ऑफ पटियाला, स्टेट बैंक ऑफ बीकानेर एंड जयपुर,स्टेट बैंक ऑफ मैसूर, स्टेट बैंक ऑफ त्रावणकोर, स्टेट बैंक ऑफ हैदराबाद और भारतीय महिला बैंक शामिल थे। यह मर्जर अप्रैल 2017 में हुआ था।

EMISAT launched
India’s Polar Satellite Launch Vehicle (PSLV-C45) on 1 April 2019 successfully launched EMISAT and 28 international customer satellites from Satish Dhawan Space Centre (SDSC) SHAR in Sriharikota. This flight marked the first mission of PSLV-QL, a new variant of PSLV with four strap-on motors. PSLV-C45 lifted off at 9:27 Hrs (IST) from the Second Launch Pad and injected India’s EMISAT into a 748 km sun-synchronous polar orbit, 17 minutes and 12 seconds after liftoff. After separation, the two solar arrays of EMISAT were deployed automatically and the ISRO Telemetry Tracking and Command Network at Bengaluru assumed control of the satellite. In the coming days, the satellite will be brought to its final operational configuration.

Anti-dumping duty on solar cell component
India has imposed anti-dumping duty of up to USD 1,559 per tonne on imports of a certain type of sheet used in solar cell making from China, Malaysia, Saudi Arabia and Thailand for five years to safeguard domestic players against cheap shipments. In a notification, the Department of Revenue has said that after considering the recommendations of the commerce ministry’s investigation arm DGTR, it is imposing the duty, which is in the range of USD 537 to USD 1,559 per tonne, on imports of “Ethylene Vinyl Acetate sheet for solar module” being exported by these four nations. The anti-dumping duty imposed shall be effective for a period of five years (unless revoked, superseded or amended earlier). Following a complaint by a domestic company, the directorate had initiated the probe in April last year.

ISRO PSLV-C56 mission successful
GS Paper - 3 (Space Technology)

India space agency, ISRO, on 30 July 2023 successfully launched its proven PSLV rocket carrying seven Singaporean satellites from Satish Dhawan Space Centre, Sriharikota. After lift-off, the primary satellite got separated and it was followed by six other co-passenger satellites, which were deployed into the intended orbits sequentially.

The primary payload

The primary payload carried by ISRO's trusted workhorse Polar Satellite Launch Vehicle is the DS-SAR Radar Imaging Earth Observation satellite, which has been developed under a partnership between DSTA (representing the Government of Singapore) and ST Engineering, Singapore.
The 360-kg satellite, upon deployment at an altitude of 535 km into a Near-equatorial Orbit (NEO), would be used to support the satellite imagery requirements of various agencies within the Government of Singapore.
ST Engineering would use the satellite for multi-modal and higher responsiveness imagery and geospatial services for their commercial customers.
The satellite carries a Synthetic Aperture Radar (SAR) payload developed by Israel Aerospace Industries.
The payload allows DS-SAR to provide for all-weather day-and-night coverage and it is capable of imaging at 1-metre resolution.

The co-passenger satellites are:

VELOX-AM, a 23 kg technology demonstration microsatellite
ARCADE Atmospheric Coupling and Dynamics Explorer (ARCADE), an experimental satellite
SCOOB-II, a 3U nanosatellite flying a technology demonstrator payload
NULloN by NuSpace, an advanced 3U nanosatellite enabling seamless Internet of Things connectivity in both urban and remote locations
Galassia-2, a 3U nanosatellite that would be orbiting at low earth orbit
ORB-12 STRIDER, a satellite developed under an international collaboration.

About Launch Vehicle

This mission is the 58th flight of PSLV and using the 17th vehicle with Core Alone Configuration.
A Core Alone version of the rocket means the vehicle would not use solid strap-on motors on its sides in the first stage as compared to other variants like PSLV-XL, QL, and DL which use six, four, or two boosters, respectively.
PSLV has earned its title as the 'Workhorse of ISRO' through consistently delivering various satellites into low earth orbits.
This is the second campaign to be undertaken by ISRO after the much-awaited Chandrayaan-3 mission which was launched on 14 July 2023 from the second launch pad, at Satish Dhawan Space Centre.

Satellite bus technology transfer to private firm
GS Paper- 3 (Space Technology)

ISRO said it has transferred the IMS-1 Satellite Bus Technology to Alpha Design Technologies Pvt. Ltd in a step towards enhancing private industry participation in the country's space sector. NewSpace India Limited (NSIL), the commercial arm of ISRO, facilitated the technology transfer through an agreement signed during an event held at the NSIL headquarters 2, the space agency said.

More about the News

The technology transfer documents were formally handed over by D Radhakrishnan, Chairman and Managing Director of NSIL to Col. H S Shankar (Retd.), Chairman and Managing Director of ADTL.
ADTL is one of the two private players identified to receive the transfer of this technology through Interest Exploratory Note (IEN) published by NSIL.
This transfer marks the beginning of satellite bus technologies developed by ISRO being transferred to private industries. Further, the PSLV is under productionisation by a consortium of industries.
ISRO has been enabling private players to develop space technologies by facilitating and extending the expertise thus ensuring both out-bound and in-bound approaches.
By transferring the IMS-1 technology to the private sector, ISRO/DoS (Department of Space) aims to bolster India's industrial growth in the space sector and foster technological self-reliance, it further said, adding the development opens up new avenues for private players to contribute to space research and exploration, in line with India's vision to expand its presence in the global space market.

About Satellite bus

The satellite bus, developed by ISRO's U R Rao Satellite Centre (URSC), is a versatile and efficient small satellite platform designed to facilitate low-cost access to space.
The bus serves as a dedicated vehicle for various payloads, enabling earth imaging, ocean and atmospheric studies, microwave remote sensing, and space science missions while ensuring a quick turnaround time for satellite launches.
The IMS-1 bus, weighing about 100 kg, accommodates a 30kg payload. Solar arrays generate 330W power with a raw bus voltage of 30-42 V, ISRO said, adding it offers a 3-axis stabilised with four reaction wheels with a 1 Newton thruster that provides +/- 0.1 degree pointing accuracy.
It is a forerunner for IMS-2 bus technology, capable of improved features, and IMS-1 bus is utilised in previous ISRO missions like IMS-1, Youthsat and Microsat-2D.

About ADTL

Alpha Design Technologies Pvt. Ltd (ADTL) is an aerospace and defence company, with expertise in engineering, manufacturing, and system integration.
It has been a key player in various projects related to defence, space and homeland security, contributing significantly to India's technological progress in these domains.
