NASA's OSIRIS-REx mission collected samples from asteroid Bennu, revealing its composition of ancient stardust, organic compounds, and water-containing minerals, providing insights into the early solar system and the origins of life.
NASA scientists successfully developed and used special tools to finally undo the last two stubborn screws on the container holding samples from the OSIRIS-REx mission, allowing access to rocks and dust from the 4.6-billion-year-old asteroid Bennu. The screws had posed a challenge due to the need to preserve the integrity of the asteroid sample within a delicate environment. After extensive testing and development, the team celebrated their success on Twitter and will now analyze the Bennu samples before cataloging and preserving them.
NASA has successfully opened the canister containing the bulk of the asteroid Bennu sample collected by the OSIRIS-REx spacecraft. The sample, estimated to be 8.8 ounces, will be transferred into smaller trays for further analysis and storage at NASA's Johnson Space Center. The spacecraft, which snagged pieces of the asteroid in 2020 and returned to Earth in 2023, faced challenges in opening the canister but has now surpassed its goal of bringing at least 2.12 ounces of material. The asteroid bits will be analyzed by a global team of scientists to gain insights into the origins of the solar system, with some samples to be made available for public display.
NASA successfully accessed the asteroid Bennu sample container, revealing a high-resolution image of the dust and rocks collected by the OSIRIS-REx spacecraft. The material, estimated to be about 4.5 billion years old, may provide insights into the formation of the solar system and the origins of life on Earth. Scientists plan to extensively analyze the sample using microanalytical techniques, having already discovered signs of carbon and water. While the team had aimed for 2.1 ounces of regolith, they obtained 2.48 ounces, with plans to spend the next two years analyzing portions of the sample and preserving the majority for future studies.
NASA's OSIRIS-REx mission has revealed the remaining sample of asteroid Bennu in high-resolution detail after overcoming challenges with the canister. The team successfully removed the final fasteners on January 10, allowing access to the sample. The next steps involve transferring the sample into trays for analysis and storage at NASA's Johnson Space Center. With over 70 grams already collected, the team has surpassed their goal and anticipates releasing a catalog of all Bennu samples later this year.
NASA has successfully removed the lid from the capsule containing the Bennu asteroid sample, after two screws caused a delay. The 250g sample will now be analyzed for insights into the solar system's history. The $1.16 billion OSIRIS-REx mission, which collected the sample in October 2020 and returned to Earth in September 2021, marks a significant achievement for NASA's space exploration efforts. The asteroid, classified as a carbonaceous chondrite, is expected to provide valuable information about the composition and origins of asteroids in the solar system.
Scientists analyzing the samples of the Bennu asteroid brought back to Earth by NASA have been surprised by the high levels of magnesium, sodium, and phosphate found in the samples' skin, a composition rarely seen in meteorites. Further analysis is needed, including accessing the heart of the material still inside the sample return canister. The samples collected so far, including a large rock that jammed the spacecraft's collection mechanism, are proving to be baffling and intriguing for scientists.
French cosmochemist Guy Libourel and his team at the Valbonne lab in France are analyzing 100 milligrams of tiny grains from NASA's OSIRIS-REx sample return mission to the asteroid Bennu. The analysis has revealed surprises, including the presence of iron oxide, sulfides, manganese, magnesium, and silicate serpentines that indicate the presence of water on Bennu. The samples, which date back 4.567 billion years, are being analyzed using a newly improvised method of cathodoluminescence, allowing researchers to study the mineralogy in detail. The pristine nature of the samples, preserved in nitrogen, provides a unique opportunity to understand the primitive character of Bennu.
NASA is facing a challenge in studying the sample collected from the asteroid Bennu as they are unable to open the Touch-and-Go Sample Acquisition Mechanism (TAGSAM) due to two fasteners that cannot be removed with the current tools. The team has accessed 70.3 grams of rocks and dust from outside and inside the sample head, surpassing their initial goal, but there is still material inside that remains inaccessible. The tools used must fit inside a glovebox to maintain sample purity and prevent contamination.
Scientists are excited about the initial assessment of asteroid samples returned by NASA's OSIRIS-REx spacecraft, which showed evidence of water and a high abundance of carbon. The samples, obtained from the asteroid Bennu, are expected to help scientists understand the formation of the solar system and the building blocks of life on Earth. The analysis was based on a small amount of material, and efforts to open the sampling head are being slowed down by the presence of an unexpected "extra bonus sample." The exact amount of material returned is still unknown, but initial results have already thrilled the scientists involved in the mission. The overall process of curating the samples will take two years, with some samples being transferred to partner agencies and others preserved for future study.
NASA has announced that a sample taken from the surface of the near-Earth asteroid Bennu contains abundant water and carbon, providing further evidence for the theory that life on Earth was seeded from outer space. The sample, collected by the OSIRIS-REx spacecraft, also contains iron minerals. Preliminary analysis suggests that the asteroid sample could offer insights into the formation of our solar system, the origins of life on Earth, and the need for precautions against asteroid collisions. The sample is currently being studied by scientists, who describe it as an "astrobiologist's dream."
NASA's OSIRIS-REx spacecraft returned to Earth with an overflowing sample container filled with asteroid Bennu material, shedding samples into space during its journey. The sample analysis team is now examining the container, covered in black particles, to learn more about the origin of life in the solar system. In another story, a cat walking across a keyboard allegedly caused a four-hour interruption in services at a Veterans Affairs Medical Center in Kansas City, Missouri, highlighting the mischievous nature of cats. Additionally, concerns have been raised about the potential surveillance capabilities of food delivery robots, as emails between Serve Robotics and the LAPD reveal the use of robot camera footage to arrest suspects. Lastly, physicists have confirmed that there is no such thing as antigravity, as regular gravity acts on antimatter the same way it does on regular matter.
NASA's OSIRIS-REx mission successfully delivered rare samples from the asteroid Bennu to a curation facility in Houston. Scientists were surprised by the abundance of material found in the canister, including "dark particles" that are slowing down the curation process. Preliminary analysis of the samples is underway to determine if they contain organic-rich particles or hydrated minerals, providing insights into the origins of Bennu and the early stages of our solar system.
Scientists have opened the canister containing a half-pound sample of material collected from the asteroid Bennu by NASA's OSIRIS-REx mission. The capsule landed in the Utah desert and was quickly transported to a curation facility in Houston. Although the exact amount of rock collected is still unknown, scientists are hopeful that the black dust-like material visible in the canister is from Bennu. The next step is to analyze the samples, which could provide valuable insights into the early stages of our solar system.
Scientists have opened the canister containing samples from asteroid Bennu, finding black dust and debris on the avionics deck. The debris most likely came from Bennu itself when the spacecraft landed on the asteroid in October 2020. The canister will be disassembled to access the bulk of the sample, which includes an estimated 8.8 ounces of asteroid rock and dust. Researchers will analyze the dust for insights into its chemical, mineralogical, and physical characteristics. Early findings and images will be revealed during a live broadcast on October 11.
