The return of NASA osiris-rex mission marks a historic milestone in planetary science as the first US mission to collect and deliver a sample from a near-Earth asteroid. These carbonaceous fragments from 101955 Bennu serve as primordial time capsules, offering scientists direct access to material that has remained largely unchanged since the formation of our solar system 4.5 billion years ago. Analyzing these samples provides essential data regarding the chemical composition of early space matter and the potential origins of organic compounds and water on Earth. This achievement advances our understanding of orbital mechanics and the geotechnical properties of asteroid surfaces, informing future planetary defense and deep space exploration strategies.#NASA #Science #SpaceExploration #Bennu #Astrophysics

Organic #molecules delivered from #extraterrestrial materials may have played a key role in supplying building blocks for #life on #Earth.
Now scientists report all five canonical #nucleobases—purines (#adenine and #guanine) and pyrimidines (#cytosine, #thymine and #uracil)—in samples returned from the C-type #asteroid (162173) #Ryugu.
Samples from Ryugu, #Bennu and #Orgueil, which have a similar mineralogy and elemental composition, show purine-to-pyrimidine ratios negatively correlating with #ammonia.
These observations indicate that the nucleobases in these samples may have formed via a shared pathway depending on the physicochemical environment of the respective parent bodies.
The detection of diverse nucleobases in asteroid and meteorite materials demonstrates their widespread presence throughout the Solar System and reinforces the hypothesis that carbonaceous asteroids contributed to the #prebiotic chemical inventory of early Earth.

#NASA Finds Building Blocks Of Life On Frozen Asteroid
Scientists have found evidence that #aminoacids, the chemical building blocks of life (specifically proteins), formed on the asteroid #Bennu when it was so far from the Sun as to be frozen. This directly contradicts previous belief that amino acids required liquid #water to form, through a process called Strecker synthesis. The scientists studied samples from Bennu retrieved by NASA's #OSIRISREx, published last week.

All the essential ingredients to kick-start #life as we know it have now been found in samples from the #asteroid #Bennu.
Asteroids could have delivered all the prerequisites for life to Earth – and perhaps elsewhere.
In 2020, OSIRIS-REx mission extracted samples from Bennu, an asteroid that was orbiting the #sun between Mars and Jupiter, and returned the samples to Earth in 2023.
Since then, small amounts of the 121 grams collected have been sent out to labs across the globe for analysis, so specialists in detecting each type of biological compound could set to work.
The first studies revealed the presence of #water, #carbon and several organic molecules. Next came the detection of amino acids, formaldehyde and all five of the nucleobases found in #RNA and #DNA, as well as phosphates.
However, this isn’t quite enough to put together the molecules that carry genetic information.
Now, scientists have revealed the presence of #ribose, as well as other sugars, including lyxose, xylose, arabinose, glucose and galactose.

#Asteroid #Bennu is a near-Earth, carbonaceous (B-type) asteroid that serves as a time capsule from the early solar system, estimated to be rich in organic molecules and water-bearing minerals.
NASA's OSIRIS-REx mission successfully collected and returned a pristine sample of its surface to Earth in 2023 for analysis, revealing building blocks of life like sugars and amino acids.
