India’s DRDO develops Single Crystal Blades for helicopter engine application; Read why it is a critical technological achievement

Defence Research and Development Organisation (DRDO) has developed single crystal blades technology and supplied 60 of these blades to Hindustan Aeronautics Limited (HAL) as part of their indigenous helicopter development program for helicopter engine application. Very few countries in the world such as USA, UK, France and Russia have the capability to design and manufacture […]

Russia and China to partner to build a lunar station – Beginning of new alliance in space race?

The deal between Chinese and Russian space agencies for a lunar station shows the strained relations between NASA and Roscosmos
Russia and China did not sign the NASA established the “Artemis Accords”, a series of bilateral agreements with various space agencies
The latest Russia-China agreement for the same purpose is now seen as a counter to the US led lunar consortium.
Another aspect which resulted in the Russia-China space partnership is strained relations between US and China.
On the other hand, Indian, Japanese and European space agencies are joining hands for several joint missions.
Alliances is a norm in deep space exploration but forming of different alliances for the same purpose may be a precursor to the ensuing ‘space race’.

ISRO completes development of Radar for joint earth observation satellite mission with NASA, to be launched in 2022

The Nasa-Isro Synthetic Aperture Radar (NISAR) is a collaboration between the Indian and US space agencies for a dual-frequency L and S-band SAR for earth observation
The NISAR Mission will measure Earth’s changing ecosystems, dynamic surfaces, and ice masses providing information about biomass, natural hazards, sea level rise, and groundwater, and will support a host of other applications.
NISAR will observe Earth’s land and ice-covered surfaces globally with 12-day regularity on ascending and descending passes, sampling Earth on average every 6 days for a baseline 3-year mission.
NISAR is the first satellite mission to collect radar data in two microwave bandwidth regions, called the L-band and the S-band, to measure changes in our planet’s surface less than a centimeter across.

Indian Scientists develop low-cost optical spectrograph that can locate sources of faint light from distant galaxies

Indigenously designed and developed ‘Made in India’ spectrograph, commissioned on Devasthal Optical Telescope, can locate faint light from distant celestial objects
The spectroscope, the largest of its kind among the existing astronomical spectrographs in the country, has been successfully commissioned on the 3.6-m Devasthal Optical Telescope (DOT), the largest in the country and in Asia, near Nainital Uttarakhand.
Expertise from various national institutes, organizations, including the ISRO and some MSMEs, were involved to review and build parts of the instrument serving as an example of effective collaboration.

Kodaikanal Solar Observatory Digitized Data probes Sun’s rotation over the Century, Provides way to predict solar cycles

Scientists have estimated how the Sun has rotated over a century from data extracted from old films and photographs that have been digitized. This estimation would help study magnetic field generated in the interior of the Sun, which causes sunspots and results in extreme situations like the historical mini-ice age on Earth (absence of sunspots). It could also help predict solar cycles and their variations in the future.

Indian Scientists develop molecule that could be a potential candidate to treat Alzheimer’s

Scientists have developed a small molecule that disrupts the mechanism through which neurons become dysfunctional in Alzheimer’s disease (AD). The molecule could be a potential drug candidate to halt or cure the leading cause of dementia (70-80%) worldwide. In the Alzheimer’s brain, abnormal levels of naturally forming protein clump together to form plaques that collect […]
