Northrop Grumman and the U.S. Space Force say converted launch vehicle payload adapter rings, upgraded with power and propulsion to create full-fledged satellites, are proving effective in more rapidly delivering military instruments and sensors to orbit. Another such mission is set to launch on a SpaceX Falcon Heavy rocket Saturday.
NASA's Perseverance Mars rover snapped a photo recently of its robotic cousin Ingenuity as the tiny helicopter rested on a Red Planet sand dune.
The first prequel-era Ultimate Collector Series set in over a decade is a fine addition to Lego Star Wars’ premium range of adult-targeted models.
Scientists have discovered a wealth of organic compounds within a Martian meteorite, which could help researchers discover if Mars could have hosted life.
Astronomers involved with the discovery of comet C/2022 E3 (ZTF) are just as excited about its discovery as the public is.
The brilliant green comet C/2022 E3 (ZFT) has captivated astrophotographers and may even become visible to the unaided eye soon.
NASA's latest flagship telescope is still in its first year of science, but the agency isn't only hard at work building its successor — it's starting to plan that next mission's successor as well.
On Friday the 13th, Saturn is still well above bright Venus in twilight. Watch them close toward their conjunction on the 22nd. Jupiter and fading Mars shine high. Sirius sparkles below Orion, and the ascendant Big Dipper stands on its handle.
Ingenuity, the helicopter assisting NASA’s Mars Perseverance rover on its mission, has been a huge success. It gathered the achievement of the first controlled flight on another heavenly body, has performed spectacularly over its 28 flights and holds records for both speed and distance. But it might not for long, as a much bigger, more capable helicopter is currently under development. And when it eventually explores Titan in the next decade, it has an excellent chance to smash many of Ingenuity’s records.
After a quarter-century of development, NASA’s James Webb Space Telescope is a smashing success. But senior project scientist John Mather, a Nobel-winning physicist who’s played a key role in the $10 billion project since the beginning, still sees some room for improvement.
Clusters of galaxies do not appear in an instant. Instead they gradually form through the accumulation of many galaxies. But when galaxies fall in they don’t just stop moving. Instead, they keep moving around. These are called backsplash galaxies, and astronomers are using them to help understand the formation history of their home clusters.
The James Webb Space Telescope is the most powerful telescope ever launched into space. That power has led to a string of observational successes: ancient galaxies, obscured star-forming regions, and an exoplanet atmosphere. Now the telescope has identified its first exoplanet, and it’s a rocky planet the same size as Earth.
Despite everything astronomers have learned about the nature and structure of galaxies, there are still mysteries about the Milky Way. The reason for this is simple: since we are embedded in the Milky Way’s disk, we have difficulty mapping it and observing it as a whole. It’s also very challenging to observe the center of the galaxy, what lies beyond it, and features in the disk itself because of all the gas and dust between stars- the Interstellar Medium (ISM). However, by observing the Milky Way in the non-visible spectrum (radio, x-ray, gamma-ray, etc.), astronomers can see more of what’s out there.
NASA's newest tiny lunar probe is battling a thruster glitch on its way to the moon.
An Airbus satellite spotted SpaceX's huge Starship vehicle on the launch pad in South Texas being prepped for a landmark test flight.
If we ever detect an Extraterrestrial Civilization (ETC) and start communicating with them, the messages could take years, decades, or even centuries to travel back and forth. We face a challenging 49-minute long delay just communicating with the Juno spacecraft orbiting Jupiter, and that’s well within our Solar System. Communicating with an ETC that’s hundreds of light-years away or even further is a daunting task.
The important stuff, if mentioned at all, wasn't part of the build-up to the Artemis story about NASA finally returning to the moon after 50 years or so.
The ODNI's report shows that the U.S. government appears to be taking UFOs and airspace safety issues seriously.
Researchers may be able to explain the origin of these enigmatic worlds and also that of other rocky planets and moons, including Earth and its siblings.
NASA's James Webb Space Telescope has revealed dozens of galaxies that could be among the earliest known galaxies in the universe.
