Integrated photonics meets electron microscopy
The transmission electron microscope (TEM) can image molecular structures at the atomic scale by using electrons instead of light, and has revolutionized materials science and structural biology. The past decade has seen a lot of interest in combining electron microscopy with optical excitations, trying, for example, to control and manipulate the electron beam by light. But a major challenge has China aims to complete space station in another huge year in space
China’s main space contractor will target more than 40 orbital launches this year, including completion of the Tiangong space station, following 48 successful launches in 2021.
Design flaw blamed for failed debut of South Korea’s new satellite launcher
The failed October debut of South Korea’s KSLV-2 rocket is being blamed on improperly anchored helium tanks inside the three-stage rocket’s upper stage.
Connecting the Dots | Addressing the V-band disconnect
As the next wave of non-geostationary satellite constellations seeks U.S. Federal Communications Commission permission to operate in V-band, antenna makers are racing to make business cases viable in this Extremely High Frequency (EHF) area of radio spectrum.
Space SPACs look to rebound in 2022
Space companies used mergers with special purpose acquisition corporations, or SPACs, to grow their businesses in 2021, but many shareholders were left underwater at the end of the year.
Video: Orbital badminton in 360 degrees
Experience an orbital badminton match on the International Space Station ISS in 360° as ESA astronaut Matthias Maurer challenges his crewmates and Japanese spaceflight participants Yusaku Maezawa and Yozo Hirano.
Together with Roscosmos cosmonaut Alexander Misurkin, the Japanese spaceflight participants joined the current Expedition 66 crew for a short-term stay of 12 days on the ISS.
While their stay on the ISS focuses on scientific and operational activities, the astronauts on board the Space Station also enjoy recreational activities that provide an important balance for the crew and offer opportunities for intercultural exchange and team building.
Matthias was launched to the International Space Station on Crew Dragon Endurance as part of Crew-3 at 02:03 GMT/03:03 CET Thursday 11 November 2021. His ESA mission on board is known as Cosmic Kiss and will see him live and work for approximately six months in orbit.

Liquid-metal experiment provides insight into the heating mechanism of the sun's corona
Why the sun's corona reaches temperatures of several million degrees Celsius is one of the great mysteries of solar physics. A "hot" trail to explain this effect leads to a region of the solar atmosphere just below the corona, where sound waves and certain plasma waves travel at the same speed. In an experiment using the molten alkali metal rubidium and pulsed high magnetic fields, a team from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), a German national lab, has developed a laboratory model, and for the first time experimentally confirmed the theoretically predicted behavior of these plasma waves—so-called Alfvén waves—as the researchers report in the journal Physical Review Letters.
James Webb telescope begins crucial sun shield tensioning
The James Webb Space Telescope began one of the most complicated parts of its deployment Monday as NASA sent commands to fully extend the first layer of the observatory's critical five-layer sunshield.
The $10 billion space telescope - the largest and most powerful in history - still is in the first half of its 29-day deployment schedule as it flies through space to a position over on India’s space program looks to bounce back
After a year marked by little launch activity and one high-profile failure, the head of India’s space program says he expects much more in 2022, including an uncrewed test flight for its human spaceflight program.
