During the past 25 years astronomers have discovered a wide variety of exoplanets, made of rock, ice and gas, thanks to the construction of astronomical instruments designed specifically for planet searches. Also, using a combination of different observing techniques they have been able to determine a large numher of masses, sizes, and hence densities of the planets, which helps them to estimate

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

China's Mars probe Tianwen-1 is traveling at a speed of 4.8 km per second in the Mars orbit, and is expected to land on the red planet in May or June, a senior space expert said on Thursday. The probe is functioning normally and has sent home China's first high-definition images of Mars, which contain a large quantity of scientific information, said Bao Weimin, director of the Committee of

NASA has awarded the Mars Ascent Propulsion System (MAPS) contract to Northrop Grumman Systems Corporation of Elkton, Maryland, to provide propulsion support and products for spaceflight missions at the agency's Marshall Space Flight Center in Huntsville, Alabama. Coupled with the successful touchdown of the Mars Perseverance rover, this award moves NASA and ESA (European Space Agency) one

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

President Joe Biden called NASA's Jet Propulsion Laboratory on Thursday to congratulate staff on last month's Mars rover Perseverance landing, which he said inspired the world during a difficult time. The call included thousands of JPL employees, JPL Director Michael Watkins and Swati Mohan, an operations lead for the Feb. 8 landing. Biden made the call just after 5 p.m. EST whil

Washington DC (UPI) Mar 4, 2021
Astronauts Kate Rubins and Soichi Noguchi are scheduled to conduct the 236th spacewalk in International Space Station history Friday morning. Rubins, of NASA, and Noguchi, of the Japanese Space Agency, will spend about 6 1/2 hours outside the orbiting space station starting about 7 a.m. EST. They will perform such maintenance as venting ammonia from an external fixture and instal
