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…

Former NASA Acting Administrator Steve Jurczyk delivering remarks during NASA’s 60th anniversary.NASA/Joel Kowsky Former NASA Acting Administrator Steve Jurczyk passed away Nov. 23, at the age of 61, following a battle with pancreatic cancer. During his career, which spanned more than three decades with the agency, Jurczyk rose in ranks to associate administrator, the highest-ranking civil servant, a position he held from May 2018 until January 2021. He ultimately went on to serve as acting administrator between administration changes, serving in that position from January 2021 until his retirement in May 2021. “Steve dedicated his life to solving some of the mo…

6 min read Hubble Celebrates 30th Anniversary of Servicing Mission 1 Astronaut F. 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…

Here in the Northern Hemisphere, the clear, crisp sky offers spectacular views of various objects, the most famous of all being Orion the Hunter. As we’ve previously mentioned, Orion is a great way to test your sky darkness. With the naked eye, you can easily spot this hourglass-shaped constellation. Known as an epic hunter in Greco-Roman antiqity, Orion and all its parts have many names and meanings across many cultures. In Egyptian mythology, this cons…

The CubeSats from NASA’s ELaNa 38 mission were deployed from the International Space Station on Jan. 26, 2022. Seen here is the deployment of The Aerospace Corporation’s Daily Atmospheric and Ionospheric Limb Imager (DAILI).NASA Despite their small size, the satellites launching through NASA’s CubeSat Launch Initiative (CSLI) missions have a big impact, creating access to space for many who might not otherwise have the opportunity. One recent mission tells the story of four teams of researchers and engineers who conceived, built, launched, and collected data from these shoebox-sized satellites, helping them answer a host of questions about our planet and the universe. …

“I want to help the Native community get better representation and show that we can help Native citizens get into aerospace engineering, mathematics, or [other STEM career fields]. And the Cherokee and Choctaw Nations are trying to do the same thing on their reservations. They have amazing education networks, so when I realized what they were doing, I wanted to help them be successful [in their efforts] so that they could inspire other tribes to do the same thing. “When I was talking with the Principal Chiefs of the Cherokee and Choctaw Nations, they said, ‘We need to start making decisions for our people seven generations from now.’ So, they started looking at emergi…

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. Like a rotating lighthouse …

“The goal is to get as many of the wrong ideas out of the way as early as possible. “So we’ll come up with some idea, especially on the research side, and sometimes it will seem really brilliant on the napkin or in a conversation with one other person. “[When I started working on electric aircraft propulsion,] I was not familiar with all of the electrical ins and outs. I thought power would just be available, and I could use it when I wanted it.

Discovery Alert: Watch the Synchronized Dance of a 6-Planet System The discovery: Six planets orbit their central star in a rhythmic beat, a rare case of an “in sync” gravitational lockstep that could offer deep insight into planet formation and evolution. Key facts: A star smaller and cooler than our Sun hosts a truly strange family of planets: six “sub-Neptunes” – possibly smaller versions of our own Neptune – moving in a cyclic rhythm. This orbital waltz repeats itself so precisely it can be readily set to music. This animation shows six “sub-Neptune” exoplanets in rhythmic orbits around their star – with a musical tone as each planet passes a line drawn through …

NASA NASA is working to resume science operations of the agency’s Hubble Space Telescope after it entered safe mode Nov. 23 due to an ongoing gyroscope (gyro) issue. Hubble’s instruments are stable, and the telescope is in good health. The telescope automatically entered safe mode when one of its three gyroscopes gave faulty readings. The gyros measure the telescope’s turn rates and are part of the system that determines which direction the telescope is pointed. While in safe mode, science operations …
