A commercial mission to boost NASA’s Neil Gehrels Swift Observatory ended without raising the spacecraft’s orbit, but the agency and Katalyst Space gained experience that will benefit future in-space servicing programs. Go to Source NASA is throwing extra support and money behind Boeing’s troubled astronaut capsule to get it fixed and flying again as soon as possible. Go to Source Look up at the night sky with the naked eye and it may seem like it rarely changes. Yet the universe is in constant flux. Stars drift through space, orbiting the center of the Milky Way as planets orbit them. They rotate, showing spots on their surfaces and sometimes producing violent outbursts that affect planetary […] Galaxies are like snowflakes: No two are exactly alike, even the spirals. The Hubble Space Telescope took a close look at the distant spiral NGC 4693 and found intriguing hints about its past. For one thing, this member of the Virgo Cluster seems to have a central region that’s rotating out of sync with its […] The Canadian Hydrogen Intensity Mapping Experiment (CHIME) has shown for the first time that it can detect the faint glow of hydrogen gas from deep in the universe’s past using only its own data. Go to Source Researchers at The University of Texas at Austin have rewritten a small part of Oklahoma’s geologic history with global implications for ancient life. Below the surface of the small town of Ames, Oklahoma, a meteor impact site spans miles. The crater is buried by sedimentary strata in the subsurface, but it remains an important marker […] Astronomers have cataloged billions of stars and hundreds of billions of galaxies. We have found thousands of planets orbiting stars. We can also map where galaxies sit and trace how the universe changes over time. Go to Source The moon no longer has a global magnetic field, but lunar rocks and soils still contain records of ancient magnetism. Studying the magnetic minerals in these samples can help scientists understand how the moon’s magnetic field evolved over time. Go to Source Spacecraft propulsion traditionally relies on volatile fuels and separate, bulky systems for different types of maneuvering in space. NASA is working to change that. Engineers at NASA’s Marshall Space Flight Center in Huntsville, Alabama, recently completed a series of environmental and physical tests on a new small satellite designed to make spaceflight safer and more […] SpaceX launched its enormous Starship toward orbit for the first time Monday, aiming for six full laps around Earth to prove its readiness for NASA’s Artemis moon program. Go to Source Astronomers using data from the Euclid space telescope have discovered an exceptionally faint stellar system near the Fornax dwarf galaxy. Called Fornax-7, it appears to contain only about 170 times the mass of the sun in stars. The discovery paper was posted to the arXiv preprint server on Sept. 13. Go to Source […] Three years after its first test flight, SpaceX’s Starship rocket will attempt Monday to enter Earth orbit, a key step in developing the massive launch vehicle for future missions to the moon and Mars. Go to Source Astronomers have identified what may be the first example of a new class of radio galaxy, one whose central black hole appears to have launched powerful jets on four separate occasions. High-resolution observations with the upgraded Giant Metrewave Radio Telescope (GMRT), combined with data from MeerKAT and the Very Large Array, reveal four pairs of […] Galaxies are enormous and hold hundreds of billions of stars. These stars form from cold, dense gas. Every large galaxy, including the Milky Way, is wrapped in a huge envelope of gas called the circumgalactic medium, or CGM. This reservoir of raw material stretches 10–20 times the size of the visible portion of the galaxy. […] Docking with the ISS may seem simple. However, actually doing so shows how difficult orbital mechanics can be. It’s like traveling down a highway at 28,000 km/hr (17,000 mph) and parallel parking in an open garage on a multibillion-dollar laboratory traveling at the same speed. If you try to accelerate forward, you actually drift up, […] |
