The European Space Agency is funding the development of a hypersonic space plane pathfinder, which will start flying by 2031, if all goes according to plan.

The JWST has pushed the boundaries of exoplanet characterization. But one thing it hasn't done yet is to determine if rocky exoplanets close to our Solar System can retain their atmospheres. The authors of a new study propose a new "five-scale height challenge" that will help astronomers obtain more precise atmospheric information on rocky exoplanets using Webb.
