Scientists have called for the designation of a new United Nations Sustainable Development Goal (SDG) with the aim to conserve and sustainably use Earth’s orbit, and prevent the accumulation of space junk. Go to Source Exiting Earth’s gravity takes an enormous amount of fuel and power. Due to this, spacecraft strapped to rockets are limited in their carry capacity and every gram must be accounted for. Go to Source It has been thought that plate tectonics were a significant factor in the shaping of our planet and the evolution of life. Mars and Venus don’t experience such movements of crustal plates, but then the differences between the worlds is evident. Go to Source Using the James Webb Space Telescope (JWST), astronomers have characterized the atmosphere of a hot super-Neptune exoplanet designated WASP-166 b. As a result, they found that the atmosphere of this alien world contains water and carbon dioxide. Their findings were reported Dec. 31 on the arXiv preprint server. Go to Source SpaceX completed its first launch from Kennedy Space Center for the year on Wednesday morning. A Falcon 9 carrying 21 Starlink satellites lifted off at 10:27 a.m. Eastern time from KSC’s Launch Pad 39-A. Go to Source Japanese startup ispace vowed its upcoming second unmanned moon mission will be a success, saying Thursday that it learned from its failed attempt nearly two years ago. Go to Source Two US astronauts who have been stuck for months on the International Space Station (ISS) said Wednesday they have plenty of food, are not facing a laundry crisis, and don’t yet feel like castaways. Go to Source Onboard computers are critical to space exploration, aiding nearly every spacecraft function from propulsion and navigation systems to life support technology, science data retrieval and analysis, communications, and reentry. Go to Source The early Earth was an extreme place. Asteroids pommeled the surface. Volcanoes spewed lava and carbon dioxide. The thick, toxic atmosphere lacked oxygen. Yet, in this turmoil, life emerged. Go to Source NASA astronaut Nick Hague will install patches to the agency’s NICER (Neutron star Interior Composition Explorer) X-ray telescope on the International Space Station as part of a spacewalk scheduled for Jan. 16. Hague, along with astronaut Suni Williams, will also complete other tasks during the outing. Go to Source It is still not clear what exactly fell onto a Kenyan village last month, but such events are likely to become increasingly common given the amount of space debris drifting above the planet. Go to Source Among all the challenges of voyaging to and successfully landing on other worlds, the effective collection and study of soil and rock samples cannot be underestimated. Go to Source Technicians have successfully integrated NASA’s Nancy Grace Roman Space Telescope’s payload—the telescope, instrument carrier, and two instruments—to the spacecraft that will deliver the observatory to its place in space and enable it to function while there. Go to Source In December 2024, five CubeSats deployed into Earth’s orbit from the International Space Station. Among them was LignoSat, a wooden satellite from JAXA (Japanese Aerospace Exploration Agency) that investigates the use of wood in space. Findings could offer a more sustainable alternative to conventional satellites. Go to Source New observations from the National Science Foundation National Radio Astronomy Observatory’s (NSF NRAO) Karl G. Jansky Very Large Array (NSF VLA) provide compelling evidence supporting a universal mechanism for the collimation of astrophysical jets, regardless of their origin. Go to Source |
