NASA/Sam Lott Engineers and technicians at NASA’s Marshall Space Flight Center in Huntsville, Alabama, recently installed a key component called the frangible joint assembly onto the adapter that connects the core stage to the upper part of the NASA’s SLS (Space Launch System) rocket. The cone-shaped stage adapter, called the launch vehicle stage adapter, will be part of the SLS mega rocket that will power NASA’s Artemis III mission to the Moon. The frangible joint sits atop the adapter and operates as a separation mechanism. The frangible joint is designed to break apart upon command, allowing the upper part of the rocket, NASA’s Orion spacecraft, and the crew inside O…

If spacecraft are to visit the outer solar system, they must cross the asteroid belt between Mars and Jupiter. The Pioneer mission was faced with the question of just how dangerous this asteroid belt would be to a spacecraft passing through it.NASA This illustration made on Nov. 26, 1974, by Rick Giudice shows the Pioneer 10 spacecraft traveling through the asteroid belt between Mars and Jupiter, the largest planet in the solar system. At the time, it was uncertain whether it would traverse it safely since the density of particles large enough to damage the craft was not yet known, but Pioneer 10 became the first satellite to enter and pass through the asteroid belt. …

“Trying to do stellar observations from Earth is like trying to do birdwatching from the bottom of a lake.” James B. Odom, Hubble Program Manager 1983-1990. The discovery after its launch that the Hubble Space Telescope’s primary mirror suffered from a flaw disappointed scientists who could not obtain the sharp images they had expected. But thanks to the Hubble’s built-in feature of on-orbit servicing, NASA devised a plan to correct the telescope’s optics during the first planned repair mission. The agency assigned one of its most experienced crews to undertake the complex tasks, naming Richard O. Covey, Kenneth D. Bowersox, Kathryn C. Thornton, Claude Nicollier of t…

NASA During a ceremony in Washington Nov. 30, Angola became the 33rd country to sign the Artemis Accords. The Artemis Accords establish a practical set of principles to guide space exploration cooperation among nations, including those participating in NASA’s Artemis program. NASA, in coordination with the U.S. Department of State, established the Artemis Accords in 2020 together with seven other original signatories. Since then, the Accords signatories have held focused discussions on how best to implement the Artemis Accords principles. The Artemis Accords reinforce and implement key obligations in the 1967 Outer Space Treaty. They also strengthen the comm…

Story Musgrave works in the space shuttle Endeavour’s cargo bay while the solar array panels on the Hubble Space Telescope are deployed during the final Servicing Mission 1 spacewalk. NASA In the pre-dawn hours on Dec. 2, 1993, the space shuttle Endeavour launched from Kennedy Space Center in Florida on a critical mission to repair NASA’s Hubble Space Telescope. Hubble was designed to be serviced in space with components that astronauts can slide in and out of place. But prior to launch, no one expected the first servicing mission to be of such urgency. For three years, Hubble h…

In microgravity, without the continuous load of Earth’s gravity, the tissues that make up bones reshape themselves. Bone cells readjust their behaviors—the cells that build new bone slow down, while the cells that break down old or damaged bone tissue keep operating at their normal pace so that breakdown outpaces growth, producing weaker and more brittle bones. For every month in space, astronauts’ weight-bearing bones become roughly 1% less dense if they don’t take precautions to counter this loss. Muscles, usually activated by simply moving around on Earth, also weaken because they no longer need to work as hard. This loss of bone and muscle is called atrophy. Atro…

2 min read Hubble Views a Double Cluster of Glowing Galaxies This NASA Hubble Space Telescope image of Abell 3192 holds two independent galaxy clusters. ESA/Hubble & NASA, G. Smith, H. Ebeling, D. Coe This Hubble image features a massive cluster of brightly glowing galaxies, first identified as Abell 3192. Like all galaxy clusters, this one is suffused with hot gas that emits powerful X-rays, and it is enveloped in a halo of invisible dark matter. All this unseen material – not to mention the many galaxies visible in this image – comprises such a huge amount of mass that the galaxy cluster noticeably curves spacetime around it, making it into a gravitationa…

Wolk A group of dead stars known as “spider pulsars” are obliterating companion stars within their reach. Data from NASA’s Chandra X-ray Observatory of the globular cluster Omega Centauri is helping astronomers understand how these spider pulsars prey on their stellar companions. A pulsar is the spinning dense core that remains after a massive star collapses into itself to form a neutron star. Rapidly rotating neutron stars can produce beams of radiation.
