With GSAT-18's injection into GTO, ISRO's Master Control Facility (MCF) at Hassan in Karnataka takes control of the satellite and will perform the initial orbit raising manoeuvres using the Liquid Apogee Motor (LAM) of the satellite, placing it in a circular Geostationary Orbit. GSAT-18 was PVC injection molding machine successfully launched by a heavy duty rocket of Arianespace from the spaceport of Kourou in French Guiana.

The launch was originally scheduled for yesterday, but deferred by 24 hours owing to unfavourable weather conditions at Kourou, a French territory located in northeastern coast of South America. Weighing 3,404 kg at lift-off, GSAT-18 carries 48 communication transponders to provide services in Normal C-band, Upper Extended C-band and Ku-bands of the frequency spectrum. Both of these upcoming launches are crucial for the Indian Space Programme," he added. GSAT-18 is the 20th satellite from ISRO to be launched by the European space agency and the mission is the 280th for Arianespace launcher family.Bengaluru: India's latest communication satellite GSAT-18 was today successfully launched by a heavy duty rocket of Arianespace from the spaceport of Kourou in French Guiana."I am really delighted this evening having witnessed another glorious and flawless lift-off of Ariane-5 VA-231 flight that carried GSAT-18 and Sky Muster II successfully. Pointing out that two more satellites GSAT 17 and GSAT 11 were getting ready for the launch by Arianespace during early next year, Kumar said "realisation of both these satellites is in advanced stage".Television, telecommunication, VSAT and digital satellite news gathering were a few of the services that GSAT 18 will support in coming days, he added.

The launch was originally scheduled for yesterday, but deferred by 24 hours owing to unfavourable weather conditions at Kourou.GSAT-18, built by the Indian Space Research Organisation (ISRO), aims at providing telecommunications services for the country by strengthening ISRO's current fleet of 14 operational telecommunication satellites.Like on all previous occasions, Arianespace has again provided us a magnificient textbook launch," Kumar said. "GSAT 18 is an important satellite for us that will enable the continuity of the vital communication services in our country by replacing the currently ageing satellites," the ISRO chief said. launched for India's space agency & more to come.GSAT-18 that aims at providing telecommunications services for the country by strengthening ISRO's current fleet of 14 operational telecom satellites was launched into a Geosynchronous Transfer Orbit (GTO) about 32 minutes after the lift-off."While GSAT 17 is an important satellite for replacing our satellites, GSAT 11 will be the first generation of high- throughput satellite of ISRO. Kumar said the next step after the successful launch of GSAT-18 was to carry out a series of manoeuvres before positioning it in its orbital location.

"The necessary preparations have been made and our team back in India is working on mission operations at Master Control Facility, Hassan," he said.Following this, the deployment of appendages such as the solar panels and antennas as well as three axis stabilisation of the satellite will be performed, and GSAT-18 will be positioned at 74 deg East longitude and co-located with other operational satellites, ISRO said. Congrats!" ISRO Chairman A S Kiran Kumar, who watched the launch from the mission control centre, left shortly after lift-off, and his message was read out later by one of his senior colleagues.The launch was originally scheduled for yesterday, but deferred by 24 hours owing to unfavourable weather conditions at Kourou."GSAT-18 successfully launched by Ariane-5 VA-231 from Kourou, French Guiana," Bengaluru-headquartered ISRO announced after the mission.ISRO, which has been dependent on Ariane-5 rocket for carrying its heavier satellites, is developing GSLV Mk III for this purpose.Announcing the successful launch of the satellite, Arianespace CEO Stephane Israel tweeted: "We take great pride in our strong relationship w/ @ISRO! Tonight marks 20 sats. Designed to provide continuity of services on operational satellites in these bands, GSAT-18 with a mission life of about 15 years, carries Ku-band beacon as well to help in accurately pointing ground antennas towards the satellite.With the weather being clear today, the European launcher Ariane-5 VA-231 blasted off at around 2 AM (IST) and injected GSAT-18 shortly after orbiting co-passenger Sky Muster II satellite for Australian operator nbn (National Broadband Network) in a flawless flight lasting about 32 minutes.GSAT-18s co-passenger Sky Muster II, built by SSL (Space Systems Loral) in Palo Alto, California, is aimed at bridging the digital divide, especially in the rural and isolated regions of Australia

Researchers at Case Western Reserve University have developed gene-carrying nanoparticles that home in on target cells and prevent vision loss in mice with a human form of Leber congenital amaurosis. Testing showed a significant increase in light-induced electrical activity from the eyes to the brain, indicating the rods and cones were operating as they should in the visual cycle.The condition is one of the most common causes of blindness in children, according to the National Institutes of Health, affecting two to three of every 100,000 newborns. The mutated gene fails to produce RPE65 protein in the retinal pigment epithelium (RPE), a cell layer critical for protecting photoreceptors .

A new gene-delivery system for an inherited form of blindness shows promise, according to a recent study. The ECO can be tailored to fit the cargo.Though this research focused on the form of the disease called Leber congenital amaurosis 2, or LCA2, the scientists and engineers involved in the study believe the technology holds promise for other forms of LCA as well as other inherited diseases that lead to severe vision loss or blindness.Lu and colleagues designed a lipid-based nanoparticle called ECO to deliver healthy RPE65 genes to RPE cells.C.Those with LAC2 carry a mutated RPE65 gene and suffer from profound vision loss from birth.The researchers are now investigating whether the ECO system is effective against other visual disorders, including Stargardt disease, which is a form of inherited juvenile macular degeneration, primarily affecting the central portion of the visual field.

The protein is an essential constituent of the visual cycle that converts light to electrical signals to the brain.The study appears in the journal Molecular Therapy Nucleic Acids.Nano-particles carrying the genes will only select target cells and prevent blindness The technology holds promise for other forms of LCA as well as other inherited diseases that lead to severe vision loss or blindness.The exterior of the nanoparticle is coated with nucleic acids that act as targeting agents, drawing the delivery system to the retina and facilitating uptake by RPE cells.The therapeutic effect lasted 120 days in treated China wholesale two color injection molding machine mice.While other researchers focus on using modified viruses to deliver genes for therapy, sometimes the genes are too large for viruses to carry, Lu said.Leader Zheng-Rong Lu said that they believe this technology can deliver almost any type of gene to tackle inherited visual disorders. They are also studying whether the nanoparticles can be used with the CRISPR/Cas9 gene-editing technique to treat genetic lesions related to retinal degenerative diseases. No improvements were observed in untreated mice. To track activity, Lu's team included a fluorescent markerFollowing injection into the retina of mice, the researchers could see fluorescent green concentrating in RPE cells.

Almost 50 per cent of Bosch’s products are connected and talk to each other.Mr Bhattacharya also said that it will have the capacity to accommodate around 2,500 associates.” While announcing the company’s annual financial results, Mr Bhattacharya spoke about the firm’s future plans. (Representational Image) Bengaluru: Automotive major Bosch is well-prepared to adopt the new tax regime, which is expected to be rolled out on July 1, but could create some turbulence, according to a top official here on Thursday. BoschSpeaking to the reporters, hybrid injection molding machine Bosch Ltd managing director Soumitra Bhattacharya said, “There could be some short-term turbulences since the new tax structure is complicated.

Bosch has significantly invested in developing new products and facilities in Bidadi and Nashik.Additionally, he said that the firm remains optimistic about the current fiscal. “A progressive government focused on reforms, reducing interest rates, expectations of a normal monsoon and improved liquidity post remonetisation, substantiates our current outlook. We aim to make it 100 per cent by 2020,” he said.While announcing the company’s annual financial results, Bhattacharya spoke about the firm’s future plans. The plant will manufacture new generation and conventional fuel injection products and components.

Overall the company made capital investments of around `630 crore in 2016-17, Mr Bhattacharaya said. He feels that the new reforms such as GST, smart cities and stable political situation will contribute to moderate growth both in the automotive as well as non-automotive sector.He feels that the new reforms such as GST, smart cities and stable political situation will contribute to moderate growth both in the automotive as well as non-automotive sector. “We would like to be a leading Internet of Things (IoT) company globally. The government needs to ensure that all the vendors are brought into the system effectively. Bosch, which has a manufacturing plant at Bidadi, said that the company expects it to be completed in 2019.. These factors have also helped improve market sentiment,” he added
