A newly discovered planet could be our best chance yet of studying rocky planet atmospheres outside the solar system, a new international study involving UNSW Sydney shows. The planet, called Gliese 486b (pronounced Glee-seh), is a 'super-Earth': that is, a rocky planet bigger than Earth but smaller than ice giants like Neptune and Uranus. It orbits a red dwarf star around 26 light-years a

On Earth, plate tectonics is not only responsible for the rise of mountains and earthquakes. It is also an essential part of the cycle that brings material from the planet's interior to the surface and the atmosphere, and then transports it back beneath the Earth's crust. Tectonics thus has a vital influence on the conditions that ultimately make Earth habitable. Until now, researchers hav

NASA and Boeing are evaluating a new target launch date for the CST-100 Starliner's Orbital Flight Test-2 (OFT-2) to the International Space Station after winter storms in Houston, and the recent replacement of avionics boxes, set the program back about two weeks. NASA also is weighing the volume of verification and validation analysis required prior to the test flight and the visiting vehicle s

Those familiar with air traffic management architectures understand the constraints of aircraft flying in the atmosphere, vehicle dynamics and command and control techniques. Unfortunately, space traffic has many more degrees of freedom and much less control capability. Add to this the completely uncontrolled nature of space debris and the reality that most debris objects cannot be tracked and m

NASA astronaut Mike Hopkins' enthusiasm for learning to grow plants in space has proven fruitful for the agency's Vegetable Production System (Veggie). The Expedition 64 crew member, who arrived at the International Space Station in November 2020 aboard NASA's SpaceX Crew-1 for a six-month science mission, has tended to multiple plant experiments on station. Astronaut Kate Rubins had alrea
