Nasa Designs Spacecraft to Hitchhike Across Comets

Nasa scientists have designed the concept of a spacecraft that would hitch rides on comets and asteroids by spearing them with tethers. Comet Hitchhiker is a concept for orbiting and landing on comets and asteroids using the kinetic energy – the energy of motion – of these small bodies. “Hitchhiking a celestial body is not as simple as sticking out ...

Indian Railways to Tie-Up With Isro to Improve Efficiency, Safety

Indian Railways will join hands with Isro to get online satellite images for improving safety and enhancing efficiency. “We will undertake a massive exercise of GIS mapping of the entire rail route and assets including buildings, land, workshops and other facilities in the network using geo-spatial technology,” said a senior Railway Ministry official involved with GIS mapping project. Geo-spatial technology ... Read More »

Hubble Survey Unlocks Clues to Star Birth in Neighbouring M31 Galaxy

After analysing images of 2,753 young, blue star clusters in the neighbouring Andromeda galaxy (M31), astronomers with the help from “citizen scientists” have found that M31 and our own Milky Way have a similar percentage of new-born stars based on mass. By nailing down what percentage of stars have a particular mass within a cluster called Initial Mass Function (IMF), ... Read More »

Nasa ‘Hedgehog’ Robots to Hop and Tumble in Microgravity

Traditional Mars rovers roll around on wheels and they cannot operate upside-down in rough terrain. To overcome this problem, Nasa scientists are building a Hedgehog robot that will hop and tumble on the surface instead of rolling on wheels. Along with researchers from Stanford University and the Massachusetts Institute of Technology, the Nasa team is building a five-kg robot that ... Read More »
