➀ NASA released a cozy 8-hour 4K fireplace video to celebrate the holiday season, featuring the heat of the SLS rocket's engines and the sounds of a crackling fire. The video is a loop of archival footage of the RS-25 engines that launched the Artemis I rocket. ➁ The Orion spacecraft reached a speed of 24,581 mph during re-entry into Earth's atmosphere. ➂ The video includes the sound of rocket engines and the crackling of wood fire, creating a warm and festive atmosphere.
➀ NASA's Curiosity rover is heading to the Boxwork area on Mars, a feature resembling spiderwebs first observed by the Mars Reconnaissance Orbiter in 2006. ➁ The Boxwork is believed to have formed from minerals settling in fractures on the Martian surface. ➂ This area is of interest due to its potential to host early Earth-like environments and its unique formation process.
➀ NASA的Webb望远镜成功捕捉到附近星系中多颗行星的图像，展示了其分析系外行星大气化学成分的能力。
➁ NASA确认詹姆斯·韦伯太空望远镜（JWST）已捕捉到地球银河系附近多个系外行星的直接图像。
➂ 通过对HR 8799行星系统的观测，Webb望远镜收集了强有力的证据，表明该系统中的四颗气态巨行星的形成方式与木星和土星相似，它们通过缓慢构建固体核心最终从原行星盘吸收气体。
➀ Astronauts on the ISS witnessed the explosion of SpaceX's Starship upper stage due to an 'energetic event';
➁ The spacecraft lost altitude and communication after the explosion;
➂ Starship initiated its RUD protocol, leading to its disassembly in the upper atmosphere.
➀ NASA has updated the impact probability of asteroid 2024 YR4 with Earth, reducing it to 0.28% for 2032, down from previous estimates.
➁ The space agency initially estimated a 1.3% chance of collision in 2032, which was then increased to 2.3% and then to 3.1% after follow-up observations.
➂ The latest observations have decreased the impact probability to just 0.28%.
➀ Researchers mistakenly identified Elon Musk's Tesla Roadster as a near-Earth asteroid.
➁ The error was corrected within a day after realizing the object's orbit matched the Falcon Heavy Upper stage with the Tesla Roadster attached.
➂ The incident highlights the need for accurate tracking of space objects and the challenges faced due to the lack of a centralized database.
➀ Elon Musk announced that President Trump requested SpaceX to return two astronauts from the ISS due to concerns with Boeing's Starliner.
➁ NASA astronauts Butch Wilmore and Suni Williams have been stuck on the ISS since June 2024 after arriving on the Boeing Starliner spacecraft.
➂ NASA decided that they would come home on Dragon after uncertainties surrounding Starliner.
➀ NASA's Hubble Space Telescope captured a 2.5 billion-pixel image of the Andromeda galaxy, our closest neighbor, set to collide with the Milky Way in 4.5 billion years.
➁ The image is a result of over 10 years of work, consisting of approximately 600 different fields of view of Andromeda.
➂ The image captures 200 million stars and provides a detailed view of Andromeda almost edge-on, giving insights into the structure and evolution of spiral galaxies.
➀ NASA has completed its assessment of the cracked heatshield on the Orion module and determined that Artemis II astronauts will be safe without a redesign. ➁ The investigation into the cracked heatshield on the Artemis I Orion module revealed that the re-entry method caused the cracks. ➂ Despite the cracks, NASA reports that the module's internal temperatures remained safe for any potential crew.
➀ NASA has designated the giant 'spiderwebs' on Mars as the next exploration target for the Curiosity rover; ➁ The rover will travel to a location known as 'boxwork' to investigate signs of ancient microbial life; ➂ Researchers believe Martian boxwork deposits could be evidence of liquid water oceans, lakes, rivers, and streams that once existed on Mars.
➀ NASA's Viking 1 spacecraft, which landed on Mars in 1975, may have inadvertently killed potential Martian life during an experiment; ➁ Astrobiologist Dirk Schulze-Makuch suggests that the water-based testing methods used could have been too harsh for Martian microbes; ➂ Schulze-Makuch recommends that NASA use multiple life-testing processes for Martian samples.
➀ SpaceX has introduced 'Marslink', a concept for high-speed internet between Mars and Earth using an adaptation of its Starlink satellite network. ➁ The system aims to provide a data relay capable of transmitting 4Mbps or more across the distance between the planets. ➃ SpaceX presented Marslink to NASA with the aim of establishing a high-speed data relay system.
➀ NASA confirms receiving a message from Voyager 1; ➁ The message was sent using a backup radio transmitter; ➂ The spacecraft experienced a communication issue and entered a protective power state.
➀ NASA has officially switched off a scientific instrument on the Voyager 2 spacecraft; ➁ The spacecraft has been sending data back to Earth for 47 years; ➂ The instrument, designed to measure plasma, was no longer useful for the spacecraft's current mission.
➀ NASA has released photographs showing the holes in the tires of its latest Mars rover, Perseverance; ➁ The holes are a result of the rover's scientific exploration on the Red Planet; ➂ The rover has been on the Martian surface since February 2021 and has faced various challenges, including tire wear.
1. NASA successfully transferred 4K video at speeds over 900 Mbps from an aircraft to the ISS. 2. The HDTN project tested the network capabilities using lasers and satellites. 3. This technology supports future missions like Artemis II and potential Mars landings.
➀ NASA's Voyager 2 spacecraft, which flew by Uranus in 1986, provided data that has puzzled scientists for decades; ➁ New research suggests that the unusual conditions observed by Voyager 2 were due to a cosmic coincidence involving space weather; ➂ The findings may indicate that the five major moons of Uranus are geologically active.
