Lunar Polar Exploration Mission
The Lunar Polar Exploration Mission (LUPEX) (also called as Chandrayaan-5) is a planned joint lunar mission by the Indian Space Research Organisation (ISRO) and Japan Aerospace Exploration Agency (JAXA). The mission would send an uncrewed lunar lander and rover to explore the south pole region of the Moon no earlier than 2028. It is envisaged to explore the permanently shadowed regions and to determine the quantity and quality of water on the Moon. JAXA is likely to provide the H3 launch vehicle and instruments and ISRO would be providing the lander. Both sides will also develop a 250kg lunar rover. LUPEX will follow the planned lunar sample-return mission Chandrayaan-4. History ISRO signed an Implementation Arrangement (IA) in December 2017 for pre-phase A, phase A study and completed the feasibility report in March 2018 with JAXA to explore the polar regions of Moon for water with a joint Lunar Polar Exploration Mission (LUPEX) that would be launched no earlier than 2028 ...

Lunar Lander
A lunar lander or Moon lander is a Lander (spacecraft), spacecraft designed to Moon landing, land on the surface of the Moon. As of 2024, the Apollo Lunar Module is the only lunar lander to have ever been used in human spaceflight, completing six lunar landings from 1969 to 1972 during the United States, United States' Apollo program, Apollo Program. Several robotic landers have reached the surface, and some have returned Moon rock, samples to Earth. The design requirements for these landers depend on factors imposed by the payload, flight rate, propulsive requirements, and configuration constraints. Other important design factors include overall energy requirements, mission duration, the type of mission operations on the lunar surface, and life support system if crewed. The relatively high gravity (higher than all known asteroids, but lower than all Solar System planets) and lack of Atmosphere of the Moon, lunar atmosphere negates the use of aerobraking, so a lander must use pr ...

Launch Vehicle
A launch vehicle is typically a rocket-powered vehicle designed to carry a payload (a crewed spacecraft or satellites) from Earth's surface or lower atmosphere to outer space. The most common form is the ballistic missile-shaped multistage rocket, but the term is more general and also encompasses vehicles like the Space Shuttle. Most launch vehicles operate from a launch pad, supported by a missile launch control center, launch control center and systems such as vehicle assembly and fueling. Launch vehicles are engineered with advanced aerodynamics and technologies, which contribute to high operating costs. An orbital spaceflight, orbital launch vehicle must lift its payload at least to the boundary of space, approximately and accelerate it to a horizontal velocity of at least . Suborbital spaceflight, Suborbital vehicles launch their payloads to lower velocity or are launched at elevation angles greater than horizontal. Practical orbital launch vehicles use chemical prope ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chandrayaan Programme
The Chandrayaan programme ( ) (Sanskrit: 'Moon', 'Craft, Vehicle', ) also known as the Indian Lunar Exploration Programme is an ongoing series of outer space missions by the Indian Space Research Organisation (ISRO) for the exploration of the Moon. The program incorporates a lunar orbiter, an impactor, a soft lander and a rover spacecraft. There have been three missions so far with a total of two orbiters, landers and rovers each. While the two orbiters were successful, the first lander and rover which were part of the Chandrayaan-2 mission, crashed on the surface. The second lander and rover mission Chandrayaan-3 successfully landed on the Moon on 23 August 2023, making India the first nation to successfully land a spacecraft in the lunar south pole region, and the fourth country to soft land on the Moon after the Soviet Union, the United States and China. Background The Indian space programme had begun with no intentions of undertaking sophisticated initiatives like h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Physical Research Laboratory
The Physical Research Laboratory ( PRL; Hindi: भौतिक अनुसंधान प्रयोगशाला, IAST: ''Bhoutik Anusandhan Prayogashala'') is a National Research Institute for space and allied sciences, supported mainly by the Department of Space, Government of India. This research laboratory has ongoing research programmes in astronomy and astrophysics, atmospheric sciences and aeronomy, planetary and geosciences, Earth sciences, Solar System studies and theoretical physics. It also manages the Udaipur Solar Observatory and Mount Abu InfraRed Observatory. The PRL is located in Ahmedabad. The Physical Research Laboratory was founded on 11 November 1947 by Dr. Vikram Sarabhai. The laboratory had a modest beginning at his residence, with research on cosmic rays. The institute was formally established at the M.G. Science Institute, Ahmedabad, with support from the Karmkshetra Educational Foundation and the Ahmedabad Education Society. Prof. K. R. Rama ...

Sky Crane (landing System)
Sky crane is a soft landing system used in the last part of the entry, descent and landing (EDL) sequence developed by NASA Jet Propulsion Laboratory for its two largest Mars rovers, ''Curiosity (rover), Curiosity'' and ''Perseverance (rover), Perseverance''. While previous rovers used airbags for landing, both ''Curiosity'' and ''Perseverance'' were too heavy to be landed this way. Instead, a landing system that combines parachutes and sky crane was developed. Sky crane is a platform with eight engines that lowers the rover on three nylon tethers until the soft landing. EDL begins when the spacecraft reaches the top of the Martian atmosphere. Engineers have referred to the time it takes to land on Mars as the "seven minutes of terror." Background The first NASA rover, ''Sojourner (rover), Sojourner'' (on the Mars Pathfinder, Mars Pathfinder lander), and twin rovers ''Spirit (rover), Spirit'' and ''Opportunity (rover), Opportunity'', used a combination of parachutes, retrorocke ...

Smart Lander For Investigating Moon
Smart Lander for Investigating Moon (SLIM), dubbed "Moon Sniper", was a lunar lander mission of the Japan Aerospace Exploration Agency (JAXA). The lander's initial launch date in 2021 was postponed until 2023 due to delays in its rideshare, the X-Ray Imaging and Spectroscopy Mission (XRISM). On 6 September 2023 at 23:42 UTC, XRISM launched, and SLIM separated from it later that day. On 1 October 2023, SLIM executed its trans-lunar orbit injection burns. The lander entered lunar orbit on 25 December 2023 and landed on 19 January 2024 at 15:20 UTC, making Japan the fifth country to soft-land a spacecraft on the Moon. News reports of technical difficulties made it to Earth, saying that the lander's solar panels were not oriented to the Sun; however, on 29 January, the lander became operational after conditions shifted. It has survived three lunar nights, awakening again in April. SLIM's operation on the Moon was terminated at 22:40 on August 23, 2024 (JST). SLIM, having surviv ...
