PARIS (ESA PR) — Today hydrazine is the most common propellant employed by thrusters aboard satellites: it is highly energetic in nature but also toxic and corrosive, as well as dangerous to handle and store. ESA initiated a study with European Astrotech Ltd in the UK to look into greener propellants and propulsion systems, to provide comparable performance with reduced toxicity and handling costs.
KOUROU, French Guiana (Arianespace PR) — Arianespace’s third mission of 2019 – which marked the Vega rocket’s 14th consecutive success – orbited the Italian PRISMA Earth observation satellite tonight, bringing the total number of spacecraft lofted by the launch services company to 600. It was the 308th flight overall of an Arianespace launcher.
The Italian Space Agency satellite will observe the Earth using a hyperspectral optical sensor, which can open up new scenarios for the control of the environmental processes of our planet
ROME (Leonardo PR) — We are getting closer to the launch of the Italian Space Agency (ASI) mission PRISMA (Hyperspectral Precursor and Application Mission). The satellite will lift off from the European spaceport of Kourou in French Guiana the night between 8 and 9 March, aboard a VEGA rocket.
From its orbit, at about 620 kilometers of altitude, PRISMA will observe the Earth on a global scale with different eyes, being equipped with an innovative electro-optical instrumentation. The Italian satellite will look at the planet with the most powerful operative hyperspectral instrument in the world, able to work in numerous, narrow and contiguous bands arranged from the visible to the near infrared (VNIR, Visible and Near InfraRed) and up to the infrared shortwave ( SWIR, Short Wave InfraRed).
WALLOPS ISLAND, Va. (NASA PR) — A NASA team has successfully demonstrated the handling and loading of a new-fangled, Swedish-developed “green propellant” that smells like glass cleaner, looks like chardonnay, but has proven powerful enough to propel a satellite.
