Blue Origin Reveals their Spacecraft Platform, Blue Ring


Blue Origin, the aerospace manufacturer and spaceflight services company founded by Jeff Bezos, recently introduced its innovative spacecraft platform named Blue Ring. 

This announcement marks a significant milestone in Blue Origin’s endeavor to offer flexible and scalable solutions for a variety of space missions. Blue Ring aims to provide a standardized yet customizable foundation for diverse payloads, scientific missions, and potential crewed flights, representing a leap forward in space technology and exploration.




Blue Origin’s Blue Ring platform is expected to be a catalyst for more accessible and innovative space exploration. As the company continues to push the boundaries of what is possible beyond Earth’s atmosphere, the foundation set by Blue Ring could play a crucial role in shaping the future of space travel and industry.


The introduction of Blue Ring could have substantial implications for the space industry, particularly for satellite deployment, space station resupply, and deep space missions. By simplifying the integration process for payloads and reducing costs, Blue Ring could make space access more attainable for a broader range of customers, from government agencies to private enterprises.


Aditya-L1's SUIT captures full-disk images of the Sun in near ultraviolet wavelengths


The Solar Ultraviolet Imaging Telescope (SUIT) instrument on board the Aditya-L1 spacecraft has successfully captured the first full-disk images of the Sun in the 200-400 nm wavelength range. SUIT captures images of the Sun's photosphere and chromosphere in this wavelength range using various scientific filters.

On November 20, 2023, the SUIT pa

yload was powered ON. Following a successful pre-commissioning phase, the telescope captured its first light science images on December 6, 2023. These unprecedented images, taken using eleven different filters (as shown in Table 1), include the first-ever full-disk representations of the Sun in wavelengths ranging from 200 to 400 nm, excluding Ca II h. The full disk images of the Sun in the Ca II h wavelength has been studied from other observatories.

Among the notable features revealed are sunspots, plage, and quiet Sun regions, as marked in the Mg II h image, providing scientists with pioneering insights into the intricate details of the Sun's photosphere and chromosphere. SUIT observations will help scientists study the dynamic coupling of the magnetized solar atmosphere and assist them in placing tight constraints on the effects of solar radiation on Earth's climate.

Chandrayaan-3 Propulsion Module moved from Lunar orbit to Earth's orbit

The primary objective of Chandrayaan-3 mission was to demonstrate soft landing near to lunar south polar region and perform experiments using the instruments on Vikram and Pragyan.


The spacecraft was launched on July 14, 2023 on-board LVM3-M4 vehicle from SDSC, SHAR. On August 23rd Vikram Lander made its historic touch down on Moon and subsequently Pragyan rover was deployed. 



The scientific instruments in Lander and Rover were operated continuously for 1 lunar day as per the defined mission life. The mission objectives of Chandrayaan-3 have been completely met. With regard to Propulsion Module, the main objective was to ferry the Lander module from GTO to the final lunar polar circular orbit and separate the Lander. 


Subsequent to separation, Spectro-polarimetry of Habitable Planet Earth (SHAPE) payload in the PM was also operated. The initial plan was to operate this payload for about three months during the mission life of PM.



 The precise orbit injection by LVM3 and optimal earth / lunar burn maneuvers, resulted in the availability of over 100 kg of fuel in the PM after over one month of operations in the lunar orbit.


 It was decided to use the available fuel in the PM to derive additional information for future lunar missions and demonstrate the mission operation strategies for a sample return mission.
