Geosynchronous Satellite Launch Vehicle Mark III
The Geosynchronous Satellite Launch Vehicle Mark III (GSLV-III), also referred to as the Launch Vehicle Mark 3 (LVM3) is a three-stage medium-lift launch vehicle developed by the Indian Space Research Organisation (ISRO). It is designed to launch satellites into geostationary orbit and is intended as a launch vehicle for crewed missions under the Indian Human Spaceflight Programme. The GSLV-III has a higher payload capacity than the similarly named GSLV. After several delays and a sub-orbital test flight on 18 December 2014, ISRO successfully conducted the first orbital test launch of GSLV-III on 5 June 2017 from the Satish Dhawan Space Centre, Andhra Pradesh. A second orbital test flight is planned for October 2018. In June 2018, the Union Cabinet approved ₹4,338 crore (US$610 million) to build 10 GSLV Mk-III rockets over a five-year period. On 15 August 2018, Indian Prime Minister Narendra Modi announced in his Independence Day speech an Indian foray into human spaceflight in 2022 with the aim of sending a crewed spacecraft called Gaganyaan to low Earth orbit. The GSLV Mk III will be the launch vehicle for this mission.

Geosynthetics
Geosynthetics are synthetic products used to stabilize terrain. They are generally polymeric products used to solve civil engineering problems. This includes eight main product categories: geotextiles, geogrids, geonets, geomembranes, geosynthetic clay liners, geofoam, geocells and geocomposites. The polymeric nature of the products makes them suitable for use in the ground where high levels of durability are required. They can also be used in exposed applications. Geosynthetics are available in a wide range of forms and materials. These products have a wide range of applications and are currently used in many civil, geotechnical, transportation, geoenvironmental, hydraulic, and private development applications including roads, airfields, railroads, embankments, retaining structures, reservoirs, canals, dams, erosion control, sediment control, landfill liners, landfill covers, mining, aquaculture and agriculture.

Geotechnical Investigation
Geotechnical investigations are performed by geotechnical engineers or engineering geologists to obtain information on the physical properties of soil and rock around a site to design earthworks and foundations for proposed structures and for repair of distress to earthworks and structures caused by subsurface conditions. This type of investigation is called a site investigation. Additionally, geotechnical investigations are also used to measure the thermal resistivity of soils or backfill materials required for underground transmission lines, oil and gas pipelines, radioactive waste disposal, and solar thermal storage facilities. A geotechnical investigation will include surface exploration and subsurface exploration of a site. Sometimes, geophysical methods are used to obtain data about sites. Subsurface exploration usually involves soil sampling and laboratory tests of the soil samples retrieved. Surface exploration can include geologic mapping, geophysical methods, and photogrammetry, or it can be as simple as a geotechnical professional walking around on the site to observe the physical conditions at the site. To obtain information about the soil conditions below the surface, some form of subsurface exploration is required. Methods of observing the soils below the surface, obtaining samples, and determining physical properties of the soils and rocks include test pits, trenching (particularly for locating faults and slide planes), boring, and in situ tests.
