An autonomous spacecraft exploring the far-flung regions of the universe descends through the atmosphere of a remote exoplanet. The vehicle, and the researchers who programmed it, don't know much about this environment.
With so much uncertainty, how can the spacecraft plot a trajectory that will keep it from being squashed by some randomly moving obstacle or blown off course by sudden, gal

Norway's Kongsberg Defence and Aerospace (Kongsberg) has placed an order for three microsatellites with Lithuanian mission integrator NanoAvionics for a space-based maritime surveillance mission covering the North Sea area. All three satellites will be based on NanoAvionics's largest satellite bus so far, the MP42 microsatellite bus.
The surveillance payload will consist of instrumentation

A relentless heat wave has blanketed India and Pakistan since mid-March, causing dozens of deaths, fires, increased air pollution, and reduced crop yields. Weather forecasts show no prospect of relief any time soon. NASA's Ecosystem Spaceborne Thermal Radiometer Experiment on Space Station instrument (ECOSTRESS) has been measuring these temperatures from space, at the highest spatial resolution

Astronauts live and work in orbit along with teaming populations of microorganisms, which could present a serious threat to health – and even the structural integrity of spacecraft. To help combat such invisible stowaways, an ESA-led project is developing microbe-killing coatings suitable for use within spacecraft cabins.

The past few weeks have been exciting ones for Perseverance's science team. At the "Enchanted Lake" site, we took our first look at what appear to be some of the bottommost sedimentary layers that make up the Jezero crater delta.
Since then, we've re-traced our steps back towards "Three Forks" and have begun the ascent of the delta near "Hawksbill Gap." It's along this Hawksbill Gap route

Astronomers have resolved the decade-long solar abundance crisis: the conflict between the internal structure of the Sun as determined from solar oscillations (helioseismology) and the structure derived from the fundamental theory of stellar evolution, which in turn relies on measurements of the present-day Sun's chemical composition.
