Engineering marvel: Sixth mirror cast for Giant Magellan Telescope

The Giant Magellan Telescope announces fabrication of the sixth of seven of the world's largest monolithic mirrors. These mirrors will allow astronomers to see farther into the universe with more detail than any other optical telescope before. The sixth 8.4-meter (27.5 feet) mirror—about two stories high when standing on edge—is being fabricated at the University of Arizona's Richard F. Caris Mirror Lab and will take nearly four years to complete. The mirror casting is considered a marvel of modern engineering and is usually celebrated with a large in-person event with attendees from all over the world. Due to the coronavirus pandemic, work on the sixth mirror began behind closed doors to protect the health of the 10-person mirror casting team at the lab.
Timelapse: Ariane 6 upper stage installed for tests

This timelapse video shows the hot firing model of the Ariane 6 upper stage being installed on the P5.2 test stand at the DLR German Aerospace Center in Lampoldshausen, Germany on 16 February 2021.
After arrival from the ArianeGroup facilities in Bremen, this 5.4 m-diameter upper stage was hoisted out of its container, tilted vertical and installed on the test stand.
Tests will simulate all aspects of flight including stage preparation such as fuelling with liquid oxygen and liquid hydrogen, and draining its tanks.
Data will be gathered on non-propulsive ballistic phases, tank pressurisation to increase performance, Vinci engine reignitions,

Mining water and metal from the moon at the same time

In-situ resource utilization (ISRU) is becoming an increasingly popular topic as space exploration begins to focus on landing on the surface of other bodies in the solar system. ISRU focuses on making things that are needed to support an exploration mission out of materials that are easily accessible at the site being explored, like European explorers in the New World building canoes out of the wood they found there.
Recently NASA's Institute for Advanced Concepts (NIAC) has started looking more closely at a variety of ISRU projects as part of their Phase I Fellows program. One of the projects selected, led by Amelia Grieg at the University of Texas, El Paso, is a mining technique that would allow explorers to dig up water, metal and other useful materials, all at the same time.
Most ISRU schemes focus on using water, as it important for many exploration efforts. However, those schemes usually discard the rest of the material that is gathered in an effort to collect the water.
