NASA unveils probe bound for Jupiter's possibly life-sustaining moon
US space scientists on Thursday unveiled the interplanetary probe NASA plans to send to one of Jupiter's icy moons as part of humanity's hunt for extra-terrestrial life. The Clipper spacecraft is due to blast off in October bound for Europa, one of dozens of moons orbiting the Solar System's biggest planet, and the nearest spot in our celestial neighborhood that could offer a perch for life.
Juice mission successfully tests Callisto flyby simulation
In preparation for a critical mission maneuver in 2031, ESA's Juice spacecraft recently completed a simulated flyby of Jupiter's moon Callisto at the ESOC mission operations center in Germany. This early test involved tricking Juice's engineering model into believing it was navigating past Callisto, to evaluate the spacecraft's autonomous navigation software. Due to the significant communi
Assessing the ages of moons from impact craters
Our solar system's giant planets-Jupiter, Saturn, Uranus, and Neptune-are surrounded by nearly 300 moons. Researchers utilize crater analysis to deduce the ages and origins of these celestial bodies. Various theories explain the creation of the solar system's moons. Predominantly, it is believed that they formed from disks of gas, dust, and pebbles that encircled nascent planets, similar t
SpaceX launches military weather satellite into orbit
SpaceX launched its second national security mission of 2024 on Thursday with a Falcon 9 rocket lifting the U.S. Space Force mission USSF-62 into orbit. The mission took off from California's Vandenberg Space Force Base at 10:25 a.m. EDT. The mission sends a Weather System Follow-on Microwave satellite, or WSF-M, to low Earth orbit. BAE Systems said it "will provide critical and
Russian rocket lifts off at third attempt
A Russian rocket blasted off for a test flight on Thursday at the third try, after previous launch attempts earlier this week were aborted in the final seconds of countdown. The flagship Angara A5 - a powerful spacecraft designed to carry heavy payloads into low Earth orbit - took off from the Vostochny Cosmodrome in the Russian Far East, a live broadcast showed. "The rocket worked acc
Kennedy Space Center Enhances Altitude Chamber for Artemis II Spacecraft Trials
As NASA prepares for the Artemis II mission, the Orion spacecraft is set for extensive testing to ensure its readiness for lunar exploration. Engineers at Kennedy Space Center have recently upgraded the altitude chamber used for these tests. The upgrades were made in anticipation of the testing phase, ensuring the spacecraft endures conditions similar to those
NASA continues Artemis program amid advancements in Starship program at SpaceX
As the race to the Moon intensifies, NASA's Artemis program and SpaceX's Starship represent two pivotal, yet distinct approaches to lunar exploration. Despite the emergence of cost-effective alternatives like SpaceX's Starship, NASA is moving forward with Artemis, underscoring its strategic, multi-faceted mission objectives beyond mere cost considerations. NASA's Artemis program is laser-f
Wireless power transmission could enable exploration of the far side of the moon
How can future lunar exploration communicate from the far side of the moon despite never being inline with the Earth? This is what a recent study submitted to IEEE Transactions on Aerospace and Electronic Systems hopes to address as a pair of researchers from the Polytechnique Montréal investigated the potential for a wireless power transmission method (WPT) comprised of anywhere from one to three satellites located at Earth-moon Lagrange Point 2 (EMLP-2) and a solar-powered receiver on the far side of the moon.
NASA technology helps guard against lunar dust
Defeating dust may be a small concern for most people on Earth, but for astronauts and spacecraft destined for the moon or Mars, it is a significant hazard that must be mitigated.
Examining the blowtorch effect of satellite reentry through video
A reaction wheel—one of the heaviest parts of a space mission, its changing rotation used to shift a satellite's orientation—seen in a plasma wind tunnel belonging to the High Enthalpy Flow Diagnostics Group (HEFDiG) at the University of Stuttgart Institute of Space Systems (IRS). Arc-heated gas in the test chamber reaches speeds of several kilometers per second, reproducing reentry conditions, while the reaction wheel itself is being rotated, reproducing the tumbling that takes place as a satellite plunges through the atmosphere.
The reaction wheel itself comes from Collins Aerospace in Germany, which has supported Design for Demise (D4D) activities for many years and introduced several modifications to their TELDIX reaction wheel, making it more likely to come apart during satellite reentry in support of demisability.
This clip was presented during this year's Space Mechanisms Workshop at ESA's ESTEC technical center in the Netherlands and focused on current and future requirements and guidelines to reduce the risk from orbital debris, including ESA's Zero Debris Charter. The event was attended by more than 130 space mechanisms specialists from European industry and academia.
