Chandrayaan-I Confirms Presence of Ice on Moon
The Chandrayaan-I spacecraft was launched in 2008 by the Indian Space Research Organisation (ISRO). On August 21, 2018, NASA scientists confirmed frozen water deposits in the darkest and coldest parts of Moon’s Polar Regions. The findings were published in the journal Proceedings of the National Academy of Sciences (PNAS), using data from the Chandrayaan-I.
First Ever 4D Printing Developed
Researchers from the City University of Hong Kong (CityU) have successfully developed the world's first-ever 4D printing for ceramics that can be used to create complex, shape-changing objects. 4D printing is conventional 3D printing combined with the additional element of time as the fourth dimension, where the printed objects can re-shape or self-assemble themselves over time with external stimuli, such as mechanical force, temperature, or a magnetic field.
Parker Solar Probe Mission Launched by NASA
NASA launched the Parker Solar Probe on August 12, 2018, at Cape Canaveral Air Force Station in Florida, US. The main aim of this historic mission to touch the sun, is to send a satellite closer to the Sun than any before.
Indian-origin Sunita Williams Amongst 9 Astronauts for Manning US Space Launch
On August 3, 2018, NASA introduced the crew of nine astronauts who will fly on American-made spacecraft to the International Space Station (ISS) from the US for the first time since the space shuttle’s retirement in 2011. The astronauts are Indian-origin Sunita Williams, Josh Cassada, Eric Boe, Nicole Mann, Christopher Ferguson, Douglas Hurley, Robert Behnken, Michael Hopkins and Victor Glover.
Oxytocin to be Sold Through Private Chemists
On August 21, 2018, the Union Government permitted the sale of Oxytocin through private retail chemists with effect from September 1, 2018. Fearing shortage of Oxytocin in the market, the government deleted the provisions of April 27, 2018, notification stating that Oxytocin would be sold through government chemists only.

In-body GPS to Track Tumours
Researchers from the Massachusetts Institute of Technology (MIT) and Massachusetts General Hospital in the United States have developed a wireless 'in-body GPS' system that can track tumours and pinpoint the location of ingestible implants inside the body. The system called ‘ReMix’ is able to easily track the implants with centimetre-level accuracy and can be used to administer drugs to specific regions in the body.
