Researchers at the Weizmann Institute created a 2D system to study fire propagation, revealing that flame dynamics follow simple laws governing penetration of liquids into porous materials. This breakthrough provides a low-cost alternative to studying fire in space and could aid in detecting slow-moving flames in aircraft.
Materials scientists will use microgravity conditions to study material formation and behavior, producing high-value products. The U.S. Laboratory Module will house three Materials Science Research Racks, with each rack capable of conducting various experiments.
Researchers have developed a unique antenna design called the Orlan antenna to provide communications and vital signs for astronauts on the International Space Station. The antenna's special loop design couples sufficient energy to transmit radio-frequency signals while minimizing reflections.
A new computer simulation shows how a small cosmic cloud could suddenly burst the heliosphere, potentially leading to catastrophic climate changes and increased exposure to deadly cosmic radiation. The simulation may help guide Voyager 1 and 2 through a series of shock waves and a massive 'wall' in space nearly two decades from now.
The Aerospace Medical Association has issued medical guidelines for air travel to help doctors advise patients with illnesses. These guidelines provide recommendations for patients with conditions such as pulmonary disease, asthma, and emphysema, emphasizing the importance of stable health before traveling.
The meeting explores hyperbaric oxygen therapy's potential in minimizing damage from strokes and preventing paralysis after spinal cord injuries. Dr. Mary Anne Frey will discuss the results of the Neurolab Space Shuttle Mission, while Sen. John Glenn will talk about his upcoming space-based research on aging.
Scientists from NASA's Marshall Space Flight Center discuss approaches to building lunar and Martian bases using in situ materials. Processing materials will be a challenge due to low gravity, which affects metal behavior and microstructure formation.
Researchers will present findings on prevention, treatment of neurological problems like stroke, epilepsy, and brain injury. The meeting aims to develop international collaborations and transfer lessons learned in space and undersea research to patient care.
The CU-Boulder payload, dubbed COLLIDE, analyzes the gentle collisions of dust particles in space to understand the dynamics of larger particles. Four different impact speeds and two different depths of dust will be tested to shed light on the mysterious disappearance of dust from planetary ring particles.
A team at University of Colorado at Boulder has found a faint, doughnut-shaped ring of interplanetary and interstellar dust orbiting Jupiter. The ring is much larger and more sparse than previously detected rings, and most particles in it move in the opposite direction to Jupiter's rotation.
The University of Colorado's Student Nitric Oxide Explorer (SNOE) satellite is successfully returning science data, measuring nitric oxide in the upper atmosphere and X-rays from the sun. The NASA mission was controlled by students and faculty 24/7, marking the second university-led satellite to be operated.
Scientists will observe how airglow changes during the eclipse to estimate oxygen densities at different altitudes in the upper atmosphere. The Polar spacecraft, equipped with a UVImager and other cameras, will take images of the Earth's shadow as the Moon's shadow moves across the globe.
The Student Nitric Oxide Explorer (SNOE) satellite, designed and built by a team of University of Colorado at Boulder students and faculty, is set for launch on Feb. 4. The mission aims to measure nitric oxide in the upper atmosphere affecting Earth's ozone layer, x-rays from the sun, and ultraviolet light from Earth's aurora.
The Near Earth Asteroid Rendezvous (NEAR) spacecraft successfully completed its Earth swingby, putting it on course for a historic encounter with asteroid 433 Eros. Scientists released the first images from the mission on January 26, providing valuable insights into the spacecraft's performance and trajectory.
The Johns Hopkins University Applied Physics Laboratory's NEAR spacecraft has detected a major gamma-ray burst, validating its instrument as a true partner in the interplanetary network. The detection expands the network to locate gamma-ray sources with greater accuracy.
The ACIS camera will record the energy of each X-ray detected from high-energy objects as unique charge, converting it into a signal to detect different elements. It has very high angular resolution and spectral resolution, allowing scientists to see individual stars for the first time in crowded regions.
Researchers will test the effects of microgravity on plant species known as sweet wormwood and rosy periwinkle, which naturally produce pharmaceutically important compounds. The goal is to develop new drugs or lower production costs.
The Large Angle and Spectrometric COronagraph Experiment (LASCO) on the SOHO spacecraft has made public images and movies taken during the week of December 22-27, 1996. The released data includes coronagraphic images and a movie with an image cadence of approximately 50 minutes.
The two miniature water worlds, designed by former Biosphere 2 crew members, have been safely transferred to the American space shuttle Atlantis for comprehensive testing of their effects on plants and animals in space. The experiments aim to provide insights into long-term human spaceflight and pharmaceutical research.
Observations by NASA's Galileo spacecraft indicate that UV radiation is breaking down Ganymede's ice into atomic hydrogen and atomic oxygen. This process could lead to the formation of molecular oxygen and ozone, which may be trapped in the ice or form a thin atmosphere above Ganymede's surface.
SRI International will operate a 150-foot parabolic reflector antenna to test UHF communication signals from the Mars Global Surveyor spacecraft. The team will analyze received signals in real-time and send simulated signals to check the UHF link for future Mars missions.
Expert researcher Juan Roederer is set to begin his long-awaited study of the radiation belts circling Jupiter after 20 years with the Galileo spacecraft. The research aims to understand how Io, one of Jupiter's moons, affects the planet's radiation belts and compare them to Earth's Van Allen belts.
The MSX satellite has released the highest resolution mid-infrared maps of the Galactic Center, providing insights into the thermal radiation from cool dust and HII regions. The images reveal hot objects like stars as blue and cool objects as red, offering a new understanding of the galaxy's structure and composition.
UC Berkeley's Center for Extreme Ultraviolet Astrophysics will take over day-to-day operations of the Extreme Ultraviolet Explorer (EUVE) observatory, fostering space science and technology innovation. The transfer aims to reduce costs and increase educational outreach through project-based learning experiences.
