Research at the Indian Institute of Science, Bengaluru and Vikram Sarabhai Space Centre, Thiruvananthapuram indicates that black carbon (BC) aerosol emissions from aircrafts could be impacting the stratospheric ozone layer. Aerosols are minute particles suspended in the atmosphere that interact with incoming and terrestrial radiation affecting the earth’s climate. Some aerosols, such as sulphates and,  nitrates cool the atmosphere. BC, on the other hand, is a positive climate forcing agent, absorbing radiation across a wide range of wavelengths.

Smart adaptive actuators are sought after for a variety of mechanical and aerospace applications. Commonly used piezoceramic and shape memory alloy actuators produce small displacements, and hence require motion amplification mechanisms. However, these mechanisms are prone to mechanical play, and are susceptible to wear and tear.

In 1959, Luna 1, a Soviet Union mission to the moon, successfully landed on the surface of the moon, kickstarting the space race between America and the Soviet that lasted for decades. Today, many countries are looking beyond our moon, and at moons of other planets like Jupiter and Saturn. Although, twelve astronauts have walked on its surface, manned missions to the moon came to a close in 1972. But the urge to study our closest neighbor never receded.

The Gravity Recovery and Climate Experiment (GRACE), a joint mission of NASA and German Aerospace Center, was launched in 2002 and has been making a detailed map of earth’s gravity field anomalies. By studying these anomalies, one can show how mass is distributed on the planet’s surface. This allows researchers to map the different features on the surface of the planet, natural and man-made ones, in great detail, while also allowing us to monitor the changes in these features.
