Like a diamond in the sky: How to spot NASA's solar sail demo in orbit
Now that its reflective sail has deployed fully open in orbit, the Advanced Composite Solar Sail System can be seen in the night sky from many locations across the world!
Stargazers can join NASA's #SpotTheSail campaign by using the NASA app on mobile platforms to find out when the spacecraft will be visible at their location. The app, which is free to use and available on iOS and Android, provides a location-specific schedule of upcoming sighting opportunities. A built-in augmented reality tool points users to the location of the spacecraft in real time.
Can you spot the solar sail? Share your viewing experience online using the hashtag #SpotTheSail for a chance to be featured on NASA's website and social media channels.
NASA scientific balloon takes flight with student-built payloads
NASA's Scientific Balloon Program's fifth balloon mission of the 2024 fall campaign took flight Wednesday, Sept. 4, 2024, from the agency's Columbia Scientific Balloon Facility in Fort Sumner, New Mexico. The HASP 1.0 (High-Altitude Student Platform) mission remained in flight over 11 hours before it safely touched down. Recovery is underway.
HASP is a partnership among the Louisiana Space Grant Consortium, the Astrophysics Division of NASA's Science Mission Directorate, and the agency's Balloon Program Office and Columbia Scientific Balloon Facility. The HASP platform supports up to 12 student-built payloads and is designed to flight test compact satellites, prototypes, and other small experiments. Since 2006, HASP has engaged more than 1,600 undergraduate and graduate students involved in the missions.
Goodnight, Cluster: brilliant end to trailblazing mission
The first satellite in ESA’s Cluster quartet safely came back down to Earth last night in a world-first ‘targeted reentry’, marking a brilliant end to this remarkable mission.
The spacecraft, dubbed ‘Salsa’ (Cluster 2), reentered Earth’s atmosphere at 20:47 CEST on 8 September 2024 over the South Pacific Ocean. In this region, any risk of fragments reaching land are absolutely minimised.
During the last two decades Cluster has spent in space, it has provided invaluable data on how the Sun interacts with Earth’s magnetic field, helping us better understand and forecast space weather. With this first-ever targeted reentry,
NASA's mini BurstCube mission detects mega blast
The shoebox-sized BurstCube satellite has observed its first gamma-ray burst, the most powerful kind of explosion in the universe, according to a recent analysis of observations collected over the last several months.
"We're excited to collect science data," said Sean Semper, BurstCube's lead engineer at NASA's Goddard Space Flight Center in Greenbelt, Maryland. "It's an important mileston ALMA observations reveal gravitational instability in planet-forming disk
Planet formation has traditionally been described as a "bottom-up" process, where dust grains gradually clump together over millions of years, forming larger structures step by step. However, a competing theory suggests that planets can form much faster via a "top-down" process, where material in a protoplanetary disk fragments due to gravitational instability.
An international team of ast 3 Questions: Evidence for planetary formation through gravitational instability
Exoplanets form in protoplanetary disks, a collection of space dust and gas orbiting a star. The leading theory of planetary formation, called core accretion, occurs when grains of dust in the disk collect and grow to form a planetary core, like a snowball rolling downhill. Once it has a strong enough gravitational pull, other material collapses around it to form the atmosphere.
A secondar Outer Solar System may hold far more objects than previously thought
New observations of the outer Solar System using the Subaru Telescope have revealed the presence of several unexpected objects, suggesting that the region may be home to a much larger population of celestial bodies than previously believed. These findings could significantly alter our understanding of the Solar System's formation and its similarities to other planetary systems, potentially influ Scientists demonstrate producing fiber materials from simulated Martian soil
A study conducted by Chinese researchers has confirmed that it is possible to continuously produce fiber materials from Martian soil, suggesting that "in-situ resource utilization" could be achieved in the construction of future Mars bases.
A research team from the Xinjiang Technical Institute of Physics and Chemistry, under the Chinese Academy of Sciences (CAS), collaborated with various China targets Mars sample-return mission by 2028
China is preparing to launch its Tianwen-3 mission with the aim of returning samples from Mars by 2028, a Chinese space expert revealed on Thursday.
Liu Jizhong, the chief designer of the Mars sample-return mission, provided details during the 2nd International Deep Space Exploration Conference held in Tunxi, Huangshan City, Anhui Province, China.
The mission's primary goal will be t Why the Martian polar caps show significant differences
For centuries, observers have watched the bright poles of Mars change with the seasons. In the last 50 years, scientists have determined that these polar caps are primarily composed of carbon dioxide that cycles in and out of the atmosphere with the seasons. However, the underlying processes driving these changes are intricate and continue to be a focus of scientific study.
