SSLV Launch Complex
SSLV Launch Complex (SLC) is the second spaceport of the Indian Space Research Organisation (ISRO), located in Kulasekarapattinam, a coastal village in Thoothukudi district of Tamil Nadu, India. The facility is being constructed over . The construction at launch site began on 5 March 2025. History In 2011, a requirement for a new launch facility at the Satish Dhawan Space Centre (SDSC) was expressed to meet future demands and as a redundancy for the existing facilities. Following this, in 2013, Kulasekarapattinam was proposed as a potential site for this launch facility by parliamentarians from the state of Tamil Nadu, citing advantages such as location, weather and proximity to ISRO facilities like the Liquid Propulsion Systems Centre. However, due to programmatic delays, the Third Launch Pad project was deprioritized as requirements to establish a new launch facility were not being met and existing facilities were augmented instead. After the ISRO began pursuing the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kulasekarapattinam
Kulasekharapattinam, also spelt Kulasekharapatnam is a town in the Thoothukudi district of Tamil Nadu, India. Historically, it was an important port on the Coromandel Coast, alongside Kaveripumpattinam (Poompuhar) and Arikamedu (near Pondicherry). From at least the 1st century CE, Kulasekharapatnam functioned as a trading hub for Pandya Dynasty. While Kollam served as a major port on the west coast, Kulasekharapatnam connected the Pandyas to Ceylon and the pearl fisheries of the Gulf of Mannar. It was part of a network of ancient coastal settlements that included Kodungallur in Kerala and Barugachha (Broach) in Gujarat. During the Colonial Era, as Tuticorin emerged as a dominant port, the prominence of Kulasekharapatnam declined. The town's name is derived from the Pandyan ruler Maravarman Kulasekara Pandyan I. Kulasekharapatnam is home to the 300-year-old Mutharamman Temple and the Dharmasamvardhini Temple, which lies north of the village. The town is particularly kno ...

Rocket Launch Sites In India
A rocket (from , and so named for its shape) is a vehicle that uses jet propulsion to accelerate without using any surrounding air. A rocket engine produces thrust by reaction to exhaust expelled at high speed. Rocket engines work entirely from propellant carried within the vehicle; therefore a rocket can fly in the vacuum of space. Rockets work more efficiently in a vacuum and incur a loss of thrust due to the opposing pressure of the atmosphere. Multistage rockets are capable of attaining escape velocity from Earth and therefore can achieve unlimited maximum altitude. Compared with airbreathing engines, rockets are lightweight and powerful and capable of generating large accelerations. To control their flight, rockets rely on momentum, airfoils, auxiliary reaction engines, gimballed thrust, momentum wheels, deflection of the exhaust stream, propellant flow, spin, or gravity. Rockets for military and recreational uses date back to at least 13th-century China. Significan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spaceports
A spaceport or cosmodrome is a site for launching or receiving spacecraft, by analogy to a seaport for ships or an airport for aircraft. The word ''spaceport''—and even more so ''cosmodrome''—has traditionally referred to sites capable of launching spacecraft into Earth's orbit, Earth orbit or on interplanetary trajectories. However, rocket launch sites for Sub-orbital spaceflight, sub-orbital Sub-orbital spaceflight, spaceflights are also sometimes called spaceports, especially as new and proposed facilities for suborbital commercial spaceflight are often branded as "spaceports." Space station, Space stations and proposed future lunar bases are also sometimes referred to as spaceports, particularly when envisioned as nodes for further interplanetary travel. Spaceports are evolving beyond traditional government-run complexes into multi-functional aerospace hubs, increasingly driven by private companies such as SpaceX, Blue Origin, and Virgin Galactic.

Thumba Equatorial Rocket Launching Station
Thumba Equatorial Rocket Launching Station (TERLS) is India's first rocket launching station and was established on 21 November 1963. Operated by the Indian Space Research Organisation (ISRO), it is located in Thumba, Thiruvananthapuram, which is near the southwestern tip of mainland India, very close to Earth's magnetic equator. It is currently used by ISRO for launching sounding rockets. The first rockets were assembled in the former St Louis High School, which now houses a space museum. The local Bishop of Trivandrum, Rev. Peter Bernard Periera, along with Vincent Victor Dereere (a Belgian) and district collector Madhavan Nair were instrumental in acquiring a large parcel of land measuring 600 acres from coastal community. Periera had given away the prayer hall and bishop's room in the local church. Minister of State for External Affairs, Lakshmi N. Menon helped to smooth bureaucratic hurdles facing the project in Delhi. H. G. S. Murthy was appointed as the first Director ...

Radiography
Radiography is an imaging technology, imaging technique using X-rays, gamma rays, or similar ionizing radiation and non-ionizing radiation to view the internal form of an object. Applications of radiography include medical ("diagnostic" radiography and "therapeutic radiography") and industrial radiography. Similar techniques are used in airport security, (where "body scanners" generally use backscatter X-ray). To create an image in conventional radiography, a beam of X-rays is produced by an X-ray generator and it is projected towards the object. A certain amount of the X-rays or other radiation are absorbed by the object, dependent on the object's density and structural composition. The X-rays that pass through the object are captured behind the object by a X-ray detector, detector (either photographic film or a digital detector). The generation of flat two-dimensional images by this technique is called Projection radiography, projectional radiography. In computed tomography (C ...

Nondestructive Testing
Nondestructive testing (NDT) is any of a wide group of analysis techniques used in science and technology industry to evaluate the properties of a material, component or system without causing damage. The terms nondestructive examination (NDE), nondestructive inspection (NDI), and nondestructive evaluation (NDE) are also commonly used to describe this technology. Because NDT does not permanently alter the article being inspected, it is a highly valuable technique that can save both money and time in product evaluation, troubleshooting, and research. The six most frequently used NDT methods are eddy-current testing, eddy-current, magnetic-particle inspection, magnetic-particle, liquid penetrant testing, liquid penetrant, radiographic testing, radiographic, ultrasonic testing, ultrasonic, and Visual inspection, visual testing. NDT is commonly used in forensic engineering, mechanical engineering, petroleum engineering, electrical engineering, civil engineering, systems engineering, a ...

Indian Ocean
The Indian Ocean is the third-largest of the world's five oceanic divisions, covering or approximately 20% of the water area of Earth#Surface, Earth's surface. It is bounded by Asia to the north, Africa to the west and Australia (continent), Australia to the east. To the south it is bounded by the Southern Ocean or Antarctica, depending on the definition in use. The Indian Ocean has large marginal or regional seas, including the Andaman Sea, the Arabian Sea, the Bay of Bengal, and the Laccadive Sea. Geologically, the Indian Ocean is the youngest of the oceans, and it has distinct features such as narrow continental shelf, continental shelves. Its average depth is 3,741 m. It is the warmest ocean, with a significant impact on global climate due to its interaction with the atmosphere. Its waters are affected by the Indian Ocean Walker circulation, resulting in unique oceanic currents and upwelling patterns. The Indian Ocean is ecologically diverse, with important ecosystems such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PSLV XL C40 Cartosat-2F Hazard Zones For Falling Stage Debris Based On NOTAM
The Polar Satellite Launch Vehicle (PSLV) is an expendable medium-lift launch vehicle designed and operated by the Indian Space Research Organisation (ISRO). It was developed to allow India to launch its Indian Remote Sensing (IRS) satellites into Sun-synchronous orbits, a service that was, until the advent of the PSLV in 1993, only commercially available from Russia. PSLV can also launch small size satellites into Geostationary Transfer Orbit (GTO). Some notable payloads launched by PSLV include India's first lunar probe Chandrayaan-1, India's first interplanetary mission, Mars Orbiter Mission (Mangalyaan), India's first space observatory, Astrosat and India's first Solar mission, Aditya-L1. PSLV has gained credibility as a leading provider of rideshare services for small satellites, owing to its numerous multi-satellite deployment campaigns with auxiliary payloads, usually ride-sharing along with an Indian primary payload. As of June 2022, PSLV has launched 345 foreign ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dogleg Maneuver
Dogleg maneuver means altering the trajectory of a satellite's launch by a sharp turn or a bend in order to avoid collisions or to avoid falling of debris in overpopulated areas. Polar satellites launched using Sriharikota spaceport of South India frequently use this maneuver to avoid flying over Sri Lanka. Rockets make a steep 40° arc in order to bypass the city of Colombo. For larger satellites, the fuel required for the maneuver is insignificant compared to the total fuel. However, the launch corridor is inefficient for smaller rockets carrying payloads to a polar orbit because the weight of extra fuel eats into the weight of payload possible. Small rockets, such as the SSLV, are specifically designed to efficiently launch smaller payloads. The additional fuel consumption for the curved trajectory compromises the rocket's cost and payload efficiency. To avoid this problem, ISRO is developing a new Kulasekharapatnam Spaceport for launching payloads to polar orbits. Given i ...

Polar Orbit
A polar orbit is one in which a satellite passes above or nearly above both poles of the body being orbited (usually a planet such as the Earth, but possibly another body such as the Moon or Sun) on each revolution. It has an inclination of about 80–90 degrees to the body's equator. Launching satellites into polar orbit requires a larger launch vehicle to launch a given payload to a given altitude than for a near-equatorial orbit at the same altitude, because it cannot take advantage of the Earth's rotational velocity. Depending on the location of the launch site and the inclination of the polar orbit, the launch vehicle may lose up to 460 m/s of Delta-v, approximately 5% of the Delta-v required to attain Low Earth orbit. Usage Polar orbits are used for Earth-mapping, reconnaissance satellites, as well as for some weather satellites. The Iridium satellite constellation uses a polar orbit to provide telecommunications services. Near-polar orbiting satellites commo ...

Azimuth
An azimuth (; from ) is the horizontal angle from a cardinal direction, most commonly north, in a local or observer-centric spherical coordinate system. Mathematically, the relative position vector from an observer ( origin) to a point of interest is projected perpendicularly onto a reference plane (the horizontal plane); the angle between the projected vector and a reference vector on the reference plane is called the azimuth. When used as a celestial coordinate, the azimuth is the horizontal direction of a star or other astronomical object in the sky. The star is the point of interest, the reference plane is the local area (e.g. a circular area with a 5 km radius at sea level) around an observer on Earth's surface, and the reference vector points to true north. The azimuth is the angle between the north vector and the star's vector on the horizontal plane. Azimuth is usually measured in degrees (°), in the positive range 0° to 360° or in the signed ...
