Europa clipper mission set to launch in October; 'message in bottle' in 103 languages
NASA's Europa Clipper mission will explore Jupiter's moon Europa for signs of life by studying its subsurface ocean, icy crust, and unique message plate with elements related to SETI. Europa Clipper’s main science goal is to determine whether there are places below the surface of Jupiter’s icy moon, Europa, that could support life. After traveling 1.6 billion miles (2.6 billion kilometers), Europa Clipper will conduct 49 close flybys of Europa, examining its subsurface ocean, icy crust, atmosphere, and space surroundings.
Reusable Launch Vehicle (RLV) landing experiment likely next week in Challakere
India's space programme conducts a landing experiment with a scaled down Reusable Launch Vehicle at Aeronautical Test Range. The test includes dropping the RLV from an altitude of 4.5km for an autonomous landing on a runway.
'Nasa paid $1 billion to this man to stop an asteroid crashing into Earth'
Dante Lauretta's book narrates Nasa's Bennu mission to prevent asteroid collisions. OSIRIS-REx's success in collecting samples from Bennu marks a pivotal achievement in planetary defense and cosmic exploration. Nasa embarked on an unprecedented mission to avert potential catastrophe from asteroid Bennu, a massive celestial body with the potential to strike Earth on September 24, 2182.
US approves first medication for severe non-alcoholic fatty liver disease
