The NIRSpec instrument is the workhorse near-infrared spectrograph on board the James Webb Space Telescope and is provided by ESA.
NIRSpec will allow scientists to study objects embedded in shrouds of gas and dust, to find out more about how galaxies formed and evolved, and to characterise the atmospheres of exoplanet to determine if water is present.
The primary goal of NIRSpec is to enable large spectroscopic surveys of astronomical objects like stars or distant galaxies. This is made possible by its powerful multi-object spectroscopy mode, which will make use of use of roughly a quarter of a
Caution! Martian wind at work
This image from ESA’s Mars Express shows part of possibly the largest single source of dust on Mars: a wind-sculpted feature known as the Medusae Fossae Formation, or MFF.

Tiny probes could sail to outer planets with the help of low-power lasers
Space travel can be agonizingly slow: For example, the New Horizons probe took almost 10 years to reach Pluto. Traveling to Proxima Centauri b, the closest habitable planet to Earth, would require thousands of years with even the biggest rockets. Now, researchers calculate in ACS' Nano Letters that low-power lasers on Earth could launch and maneuver small probes equipped with silicon or boron nitride sails, propelling them to much faster speeds than rocket engines.

Ukraine crisis challenges International Space Station cooperation
The crisis over Russia's Ukrainian aggression presents NASA and other space agencies with the most serious diplomatic strain in the 22-year history of the International Space Station partnership, experts said.
Russia is a major partner with the United States, Europe, Japan and Canada in the space station's maintenance and operation.
