Analyses of data from the Moon Mineralogy Mapper spectrometer onboard the Chandrayaan-1 spacecraft have suggested that OH/H2O is recycled on diurnal timescales and persists only at high latitudes. However, the spatial distribution and temporal variability of the OH/H2O, as well as its source, remain uncertain.

The Moon's Water May Be Widespread and Immobile

BHEL gets ISRO tech to make Li-ion cells
BHEL said it would set up a facility at its Bengaluru unit to make the cells. It would use the technology developed by ISRO’s rocketry node, Vikram Sarabhai Space Centre, based in Thiruvananthapuram.
Li-ion batteries power various applications on satellites and launch vehicles. An ISRO spokesman said the requirement would go up as the number of space missions is increasing.
Currently, BHEL assembles Li-ion batteries using imported cells.

Today, 19th April marks the launch of India’s first satellite, ‘Aryabhata’, named after Aryabhatta, the Indian astronomer of the same name.
The Aryabhata satellite was launched in the year 1975. Built by the Indian Space Research Organisation (ISRO), the satellite was launched from Kapustin Yar, a Russian rocket launch and development site in Astrakhan Oblast using a Kosmos-3M launch vehicle

Isro to launch dedicated satellite for IAF in 3rd week of December - Times of India
Costing around Rs 500-800 crore, Gsat-7A will have a lifetime of nine years. It will have Ku-band transponders and two deployable solar arrays. The satellite weighing 2.2 tonnes will be launched by GSLV Mk II.
Gsat-7A will also boost drone operations as it will help the navy upgrade from existing ground control stations to satellite-control of military unmanned aerial vehicles (UAVs). The transition will boost the range, endurance and flexibility of UAVs.
The IAF is also likely to get another satellite Gsat-7C, within a few years that will boost its network-centric operations.
