PSLV-C58
The PSLV C-58 was the 60th flight of the Indian Space Research Organisation's Polar Satellite launch Vehicle. It carried the XPoSAT mission along with rideshare payloads. Payload Besides XPoSat, the rocket carried 10 other payloads on PSLV Orbital Experiment Module (POEM) - 3. Along side them, two payloads by Indian Space Research Organisation's (ISRO) Vikram Sarabhai Space Centre (VSSC) and one by the Physical Research Laboratory (PRL) were manifested for the flight. On PSLV-C58/XPoSat campaign, POEM-3 hosted ten payloads weighing ~145 kg cumulatively. PSLV fourth stage was lowered to 350 km orbit at 9.6° inclination after deploying XPoSat to reach the POEM-3 operational orbit. For power generation and storage it will again have flexible solar panels in conjunction with 50Ah Li-Ion battery and will be three-axis stabilized. Payloads hosted on POEM-3 are following, seven of them facilitated by IN-SPACe and three are by ISRO, # Radiation Shielding Experimental Module (RS ...

PSLV Orbital Experiment Module
---- PSLV Orbital Experiment Platform (POEM) also known as PSLV Stage 4 Orbital Platform (PS4-OP) is an orbital micro-gravity test bed based on spent fourth stage of PSLV. By adding modular subsystems for power generation, communication and stabilization like photovoltaic cells, Telemetry and Telecommand (TT&C) package, attitude control system, data storage etc to the PSLV fourth stage, it can function as a satellite bus. This augmented stage can then host payloads for up to six months while in orbit, making it useful for qualifying components, gaining space heritage and conduct experiments in micro-gravity conditions. Usually the fourth stage of PSLV is discarded after deployment of satellite and remains in orbit for a significant duration in a passive state as a piece of space debris. Objective POEM or PS4-OP was conceived by VSSC/ISRO to help Indian academia and start-ups by providing a low cost platform with essential subsystems to support their payloads hence lowering the ...

XPoSat
The X-ray Polarimeter Satellite (XPoSat) is an ISRO, Indian Space Research Organisation (ISRO) manufactured space observatory to study Polarization (waves), polarisation of X-ray astronomy, cosmic X-rays. It was launched on 1 January 2024 on a Polar Satellite Launch Vehicle, PSLV rocket, and it has an expected operational lifespan of at least five years. The telescope was developed by the Raman Research Institute (RRI) in close collaboration with U R Rao Satellite Centre (URSC). As per ISRO, this mission will complement the efforts of US space agency NASA, which launched its Imaging X-ray Polarimetry Explorer (IXPE) in 2021 by observing space events across a broad energy range of 2-30 keV. Overview Studying how radiation is polarised gives away the nature of its source, including the strength and distribution of its magnetic fields and the nature of other radiation around it. XPoSat will study the 50 brightest known sources in the universe, including pulsars, X-ray binary, b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bharatiya Antariksha Station
The Indian Orbital Space Station, officially called, Bharatiya Antariksha Station (), is a planned modular space station to be constructed by India and operated by the Indian Space Research Organisation (ISRO). The space station would weigh 20 tonnes and maintain an orbit of approximately 400 kilometres above the Earth, where astronauts could stay for 15–20 days. Originally planned to be completed by 2030, it was later postponed to 2035 due to delays caused by technical issues related with the Gaganyaan crewed spaceflight mission and the COVID-19 pandemic in India. As of December 2023, the first module is expected to be launched in 2028 on an LVM3 launch vehicle, with the remaining modules to be launched by 2035 on the Next Generation Launch Vehicle. History In 2019, ISRO chief K. Sivan presented the features of the proposed space station for the first time, saying that the space station may weigh up to 20 tons. Three years later, in his New Year's speech delivered before ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PSLV-C57
The PSLV-C57 was the 59th mission of Indian Space Research Organisation's Polar Satellite Launch Vehicle (PSLV), which carried India's indigenously made solar observatory Aditya-L1. Launch It was launched on Saturday, 02 September 2023 at 11:50 IST / 06:20 UTC from Satish Dhawan Space Centre, Sriharikota, Andhra Pradesh, India. This was India's first Solar Observatory ever launched in history. Aditya-L1 was injected into an elliptical orbit of 235x19500 km around the Earth. On 6 January 2024, Aditya-L1 spacecraft, India's first solar mission, has successfully entered its final orbit with a period of approximately 180 days around the first Sun-Earth Lagrangian point (L1), approximately 1.500 million kilometers from Earth Earth is the third planet from the Sun and the only astronomical object known to harbor life. While large volumes of water can be found throughout the Solar System, only Earth sustains liquid surface water. About 71% of Earth's surfa .... ...

Silicon
Silicon is a chemical element with the symbol Si and atomic number 14. It is a hard, brittle crystalline solid with a blue-grey metallic luster, and is a tetravalent metalloid and semiconductor. It is a member of group 14 in the periodic table: carbon is above it; and germanium, tin, lead, and flerovium are below it. It is relatively unreactive. Because of its high chemical affinity for oxygen, it was not until 1823 that Jöns Jakob Berzelius was first able to prepare it and characterize it in pure form. Its oxides form a family of anions known as silicates. Its melting and boiling points of 1414 °C and 3265 °C, respectively, are the second highest among all the metalloids and nonmetals, being surpassed only by boron. Silicon is the eighth most common element in the universe by mass, but very rarely occurs as the pure element in the Earth's crust. It is widely distributed in space in cosmic dusts, planetoids, and planets as various forms of silicon dioxide ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuel Cell
A fuel cell is an electrochemical cell that converts the chemical energy of a fuel (often hydrogen) and an oxidizing agent (often oxygen) into electricity through a pair of redox reactions. Fuel cells are different from most batteries in requiring a continuous source of fuel and oxygen (usually from air) to sustain the chemical reaction, whereas in a battery the chemical energy usually comes from substances that are already present in the battery. Fuel cells can produce electricity continuously for as long as fuel and oxygen are supplied. The first fuel cells were invented by Sir William Grove in 1838. The first commercial use of fuel cells came more than a century later following the invention of the hydrogen–oxygen fuel cell by Francis Thomas Bacon in 1932. The alkaline fuel cell, also known as the Bacon fuel cell after its inventor, has been used in NASA space programs since the mid-1960s to generate power for satellites and space capsules. Since then, fuel cells have b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hall-effect Thruster
In spacecraft propulsion, a Hall-effect thruster (HET) is a type of ion thruster in which the propellant is accelerated by an electric field. Hall-effect thrusters (based on the discovery by Edwin Hall) are sometimes referred to as Hall thrusters or Hall-current thrusters. Hall effect, Hall-effect thrusters use a magnetic field to limit the electrons' axial motion and then use them to ionize propellant, efficiently accelerate the ions to produce thrust, and neutralize the ions in the plume. The Hall-effect thruster is classed as a moderate specific impulse (1,600s) space propulsion technology and has benefited from considerable theoretical and experimental research since the 1960s. Hall thrusters operate on a variety of propellants, the most common being xenon and krypton. Other propellants of interest include argon, bismuth, iodine, magnesium, zinc and adamantane. Hall thrusters are able to accelerate their exhaust to effective exhaust velocity, speeds between 10 and 80 k ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
