Hundreds of students, scientists, and other stakeholders recently gathered for a three-day symposium featuring some of the leading minds in space exploration and packed with updates and discussions about an array of space topics.
Jason Turpin, senior technical leader of propulsion at Marshall, far right, discusses advances in propulsion during the 2023 von Braun Space Exploration Symposium. Joining him onstage, from left, are Eric Paulson, who manages the Rotating Detonation Rocket Engine program at the Air Force Research Laboratory, and Tabitha Dodson, who manages the DRACO program for DARPA .Attendees could listen to the symposium live in person at UAH’s Charger Union Theater or online via Zoom.
“From the very beginning NASA has been an incredible partner,” said Joe Iacuzzo, founder and director of the Huntsville Science Festival, which is associated with the SFA . “Without NASA’s participation and incredible generosity this event would be nowhere near what it is today,” Nearly 4,000 visitors enjoyed learning about NASA missions during the 3rd annual Huntsville STEAMfest event Oct. 28 in downtown Huntsville.STEAMfest featured three science stage entertainers, who demonstrated exciting science experiments such as using an artificial lightning generating device to pop hydrogen-filled balloons creating fireballs in mid-air. An art installation inspired by science and technology was there for viewing.

Zhou et al. ; IR: NASA/JPL/CalTech/Spitzer; Image Processing: NASA/CXC/SAO/J.Schmidt Scientists surmised that SN 1006’s unique structure is tied to the orientation of its magnetic field. They theorized that supernova blast waves in its northeast and southwest sectors move in the direction aligned with the magnetic field, and more efficiently accelerate high-energy particles.
IXPE is a collaboration between NASA and the Italian Space Agency with partners and science collaborators in 12 countries. IXPE is led by NASA’s Marshall Space Flight Center. Spacecraft operations are jointly managed by Ball Aerospace in Broomfield, Colorado, and the University of Colorado’s Laboratory for Atmospheric and Space Physics in Boulder.
In 2001, NASA’s Chandra X-ray Observatory first observed the pulsar PSR B1509-58 and revealed that its pulsar wind nebula resembles a human hand. The pulsar is located at the base of the “palm” of the nebula. Now Chandra’s data of MSH 15-52 have been combined with data from NASA’s newest X-ray telescope, IXPE to unveil the magnetic field “bones” of this remarkable structure,. IXPE stared at MSH 15-52 for 17 days, the longest it has looked at any single object since it launched in December 2021.
The IXPE data provides the first map of the magnetic field in the ‘hand’. It reveals information about the electric field orientation of X-rays determined by the magnetic field of the X-ray source. This is called “X-ray polarization”. A paper describing these results by Roger Romani of Stanford University and collaborators was published in The Astrophysical Journal on Oct. 23 and is available at IXPE is a collaboration between NASA and the Italian Space Agency with partners and science collaborators in 12 countries. IXPE is led by NASA’s Marshall Space Flight Center.
“Jupiter has the most intense radiation environment other than the Sun in the solar system,” Jun said. “The radiation environment is affecting every aspect of the mission.” So even as engineers work to keep radiation out of Europa Clipper, scientists like Nordheim and Jun hope to use the space probe to study it.
Over time, these oxidants could be transported from the surface to the interior ocean. “The surface could be a window into the subsurface,” Nordheim said. A better understanding of such processes could provide a key to unlock more of the Jupiter system’s secrets, he added: “Radiation is one of the things that makes Europa so interesting. It’s part of the story.”
The JIRAM data of Ganymede obtained during the flyby achieved an unprecedented spatial resolution for infrared spectroscopy – better than 0.62 miles per pixel. With it, Juno scientists were able to detect and analyze the unique spectral features of non-water-ice materials, including hydrated sodium chloride, ammonium chloride, sodium bicarbonate, and possibly aliphatic aldehydes.
