Astronomers confirm Maisie's galaxy is among earliest ever observed
Thanks to the James Webb Space Telescope, astronomers racing to find some of the earliest galaxies ever glimpsed have now confirmed that a galaxy first detected last summer is in fact among the earliest ever found. The findings are in the journal Nature.
Follow-up observations since first detection of Maisie's galaxy have revealed that it is from 390 million years after the Big Bang. Altho Seventeen years later satellite return home for first time
On Aug. 12, 2023, NASA's STEREO-A spacecraft will pass between the Sun and Earth, marking the first Earth flyby of the nearly 17-year-old mission. The visit home brings a special chance for the spacecraft to collaborate with NASA missions near Earth and reveal new insights into our closest star.
The twin STEREO (Solar TErrestrial RElations Observatory) spacecraft launched on Oct. 25, 2006, Monster waves as tall as three suns are crashing upon a colossal star
An extreme star system is giving new meaning to the phrase "surf's up." The star system intrigued researchers because it is the most dramatic "heartbeat star" on record. Now new models have revealed that titanic waves, generated by tides, are repeatedly breaking on one of the stars in the system-the first time this phenomenon has ever been seen on a star.
Heartbeat stars are stars in close Rubin will detect an abundance of interstellar objects passing through solar system
Many as-yet-undiscovered interstellar objects exist throughout our Milky Way Galaxy: comets and asteroids that have been ejected from their home star systems. Some of these objects pass through our Solar System, bringing valuable information about how planetary systems form and evolve. Currently, only two such interstellar visitors have been discovered: 1I/?Oumuamua and comet 2I/Borisov. Rubin's SwRI micropatch algorithm improves ground-to-spacecraft software update efficiency
Southwest Research Institute developed an algorithm to remotely update and repair spacecraft software using less time and data than conventional techniques. The tool not only improves the overall efficiency of satellite software transmissions but also can recover data from failed over-the-air updates and malicious cyberattacks. It works by identifying missing bytes and other errors before deploy Communications achieved for NASA's 4 Starling CubeSats
Mission managers have established command communications with all four of NASA's Starling CubeSats! The spacecraft are progressing through payload and propulsion tests, the final stage of a pre-operations checklist called commissioning.
The Starling spacecraft - which project team members nicknamed Blinky, Pinky, Inky, and Clyde - are part of an ambitious test to develop self-coordinating Damage control: WVU researchers aim for the sky to track lethal space debris
West Virginia University researchers are looking to protect space - and elements of everyday life on Earth - from debris down to the size of paint flakes barreling through space at speeds of more than 15,000 miles per hour.
A team led by Piyush Mehta, assistant professor of mechanical and aerospace engineering in the Benjamin M. Statler College of Engineering and Mineral Resources, has rec Durable Parker Solar Probe going strong after first five years
On Aug. 12, 2018—five years ago this week—NASA's Parker Solar Probe blasted off atop a powerful Delta IV rocket from what is now Cape Canaveral Space Force Station. The predawn launch into the skies over the Florida coast marked the start of a game-changing mission to unlock the secrets of the solar wind—and the culmination of decades of development to craft a robotic explorer able to withstand the heat and radiation near the sun like no other spacecraft before it.
Designs for a "solar probe" started coming together in 1962, just four years after the National Research Council's Space Studies Board first proposed a mission to explore the environment near the sun.
Spacecraft could shuttle astronauts and supplies to and from the moon on a regular basis
Multiple space agencies plan to send astronauts, cosmonauts, and taikonauts to the moon in the coming years, with the long-term goal of establishing a permanent human presence there. This includes the NASA-led Artemis Program, which aims to create a "sustained program of lunar exploration and development" by the decade's end. There's also the competing Russo-Chinese International Lunar Research Station (ILRS) effort to create a series of facilities "on the surface and/or in orbit of the moon" that will enable lucrative research.
Beyond these government-agency-led programs, there are many companies and non-government organizations (NGOs) hoping to conduct regular trips to the moon, either for the sake of "lunar tourism" and mining or to build an "International Moon Village" that would act as a spiritual successor to the International Space Station (ISS). These plans will require a lot of cargo and freight moving between Earth and the moon well into the next decade, which is no easy task.
An improved radioisotope thermoelectric generator could dramatically reduce the weight of interplanetary missions
Radioisotope thermoelectric generators (RTGs) are the power plants of the interplanetary spacecraft. Or at least they have been for going on 50 years now. But they have significant drawbacks, the primary one being that they're heavy. Even modern-day RTG designs run into the hundreds of kilograms, making them useful for large-scale missions like Perseverance but prohibitively large for any small-scale mission that wants to get to the outer planets. Solar sails aren't much better, with a combined solar sail and battery system, like the one on Juno, coming in at more than twice the weight of a similarly powered RTG.
To solve this problem, a group of engineers from the Aerospace Corporation and the US Department of Energy's Oak Ridge National Lab came up with a way to take the underlying idea of an RTG and shrink it dramatically to the point where it could not potentially be used for much smaller missions.
