New Zealand base for methane-measuring satellite mission

A satellite mission to measure global methane emissions from oil and gas facilities will be based in New Zealand, the government said on Wednesday, in a collaboration with a U.S. environmental group. The MethaneSAT, due to be launched in 2022, is designed to locate and measure methane from human sources worldwide, and will provide data to track and reduce those emissions, the government said in a statement.

NASA probe provides insight on solar system's border with interstellar space

The journey of NASA's dauntless Voyager 2 spacecraft through our solar system's farthest reaches has given scientists new insight into a poorly understood distant frontier: the unexpectedly distinct boundary marking where the sun's energetic influence ends and interstellar space begins. The U.S. space agency previously announced that Voyager 2, the second human-made object ever to depart the solar system following its twin Voyager 1, had zipped into interstellar space on Nov. 5, 2018 at a point more than 11 billion miles (17.7 billion km) from the sun. Several research papers published on Monday provided scientific details of that crossing.
