Scientists measure the atmosphere of a planet 340 light-years away
Wednesday, 27 October 2021 19:20An international team of scientists, using the ground-based Gemini Observatory telescope in Chile, is the first to directly measure the amount of both water and carbon monoxide in the atmosphere of a planet in another solar system roughly 340 light-years away.
The team is led by Assistant Professor Michael Line of Arizona State University's School of Earth and Space Exploration, and the results have been recently published in the journal Nature.
There are thousands of known planets outside of our own solar system (called exoplanets). Scientists use both space telescopes and ground-based telescopes to examine how these exoplanets form and how they are different from the planets in our own solar system.
For this study, Line and his team focused on planet "WASP-77Ab," a type of exoplanet called a "hot Jupiter" because they are like our solar system's Jupiter, but with a temperature upwards of 2,000 degrees Fahrenheit.

NASA sending four astronauts to ISS on Sunday
Wednesday, 27 October 2021 16:24NASA is teaming up with SpaceX once more to send four astronauts to the International Space Station on Sunday, including three first-timers.
The crew of mission "Crew-3" will spend six months on the orbital outpost, conducting research in areas including material sciences, health, and botany, to help inform future deep space exploration and benefit life on Earth.
Making Martian rocket biofuel on Mars
Wednesday, 27 October 2021 14:01Researchers at the Georgia Institute of Technology have developed a concept that would make Martian rocket fuel, on Mars, that could be used to launch future astronauts back to Earth.
The bioproduction process would use three resources native to the red planet: carbon dioxide, sunlight, and frozen water. It would also include transporting two microbes to Mars. The first would be cyanobacteria (algae), which would take CO2 from the Martian atmosphere and use sunlight to create sugars. An engineered E. coli, which would be shipped from Earth, would convert those sugars into a Mars-specific propellant for rockets and other propulsion devices. The Martian propellant, which is called 2,3-butanediol, is currently in existence, can be created by E. coli, and, on Earth, is used to make polymers for production of rubber.
Physics experiment in Earth's atmosphere could help improve GPS performance
Wednesday, 27 October 2021 13:56The Earth's atmosphere has been used as a 'laboratory' to carry out a physics experiment, in research collaboration involving the University of Strathclyde which could help to improve the performance of GPS.
The study displays a new method of remotely monitoring the plasma in the ionosphere and of controlling wave modes in a way which could help GPS make better calculations in the face of extreme space weather.
The researchers conducted a controlled radar wave experiment by injecting radio waves into the ionosphere, at slightly different frequencies.
The returned signal was then recorded and analyzed. The researchers found that plasma waves were excited in the ionosphere and non-linear waves were mixed, leading to a wide spectrum of non-linear frequencies in the returned signal.
Plasma in the ionosphere plays a significant role in reflecting and modifying radio waves used for communication and radio navigation systems such as GPS, but the accuracy of these can be affected by 'space weather' events such as solar storms.
The experiment was carried out at the EISCAT facility near Tromsø, Norway and the research has been published in the journal Nature Communications.
US-South Korea joint space drills to focus on space situational awareness
Wednesday, 27 October 2021 13:36“What we urgently need is ‘eyes’ to look at what’s happening in outer space,” said ROK Air Force Col. Park Ki-tae, inaugural chief of the air force’s Space Operations Center, during the Seoul International Aerospace and Defense Exhibition 2021.
Crew-3 say cheese
Wednesday, 27 October 2021 13:09ESA astronaut Matthias Maurer and his NASA crew mates Raja Chari, Thomas Marshburn and Kayla Barron are all smiles as they arrive at NASA’s Kennedy Space Center in Florida, USA on 26 October 2021.
Collectively, the astronauts make up Crew-3 and will travel to the International Space Station on the SpaceX Crew Dragon spacecraft “Endurance”. The first launch opportunity for Crew-3 is 07:21 CET (06:21 GMT, 02:21 EDT) Sunday 31 October 2021, with a backup date of 3 November.
The Dragon will dock with the Space Station 22 hours after launch, allowing for a short overlap with the Crew-2 members who
