The mission will succeed NASA’s Cassini probe, which ended its 13-year mission orbiting Saturn in September 2017 by diving into Saturn’s atmosphere. Dragonfly mission is a part of NASA’s New Frontiers program, which includes a series of space exploration missions, which are being conducted ...
Human Space Flight Centre (HSFC): It is a newly inaugurated centre in Indian Space Research Centre (ISRO). It will be the hub of ISRO's future manned missions, was inaugurated at ISRO headquarters in Bengaluru. It will be responsible for the implementation of Gaganyaan project — which invo...
space technologySpace missions continue to demand higher power Hall thrusters that provide high thrust and long life. For in-space propulsion applications such as high-power orbit raising and cargo missions, Hall thrusters capable of operating in the range of 10–50 kW are in development. The ...

Missions 1. Introduction The detection of exoplanets with space- and ground-based telescopes has suggested that most stars in the galaxy host planets [1], [2]. A recent statistical analysis by Bryson et al. [3] examined the Kepler planet catalog and found that about half of Sun-like stars...
Similar to the recently launched Parker Solar Probe, and unlike earlier missions, Solar Orbiter carries instruments designed to measure low-frequency DC electric fields. Aims. In this paper, we assess the quality of the low-frequency DC electric field measured by the Radio and Plasma Waves ...

In recent years, demand has increased for small spacecraft that use electric propulsion systems so that they can go on space missions frequently and inexpensively, such as for deep space exploration, earth observation, and broadband constellation deployment [1]. For example, ion thrusters have been...
Musk's SpaceX, working to prove the flight-worthiness of its rocket fleet one mission at a time, aims to clinch one-third of all US National Security Space missions — coveted contracts that are worth billions of llars. The US Air Force tapped SpaceX in 2019 to launch a classified ...
“Russia should have closed the airspace over Grozny but failed to do so,” Kovalenko said.“The plane was damaged by the Russians and was sent to Kazakhstan instead of being urgently landed in Grozny to save lives.” But the fact 29 survived is extraordinary. ...
