Welcome to this week’s installment of The Intelligence Brief… as NASA and an international team recently announced the results of their recent analysis of samples collected from a distant asteroid, this week we’ll be looking at 1) what turned up in samples delivered to Earth by a Japanese spacecraft, 2) how this might suggest an off-planet origin for the building blocks of life, and 3) how future analysis of asteroid samples could reveal more about the mysterious origins of life on Earth.

Latest Stories: Before getting into our analysis this week, stories we’re covering right now include analysis of how incidents involving several objects downed over North America have renewed debate over excessive secrecy regarding what the U.S. government knows about unidentified flying objects. In similar reporting, Tim McMillan tells us why the Pentagon says it has no plans to release images of a series of unidentified objects recently shot down over the U.S. and Canada. You can find links to all our recent stories at the end of this week’s newsletter.
Podcasts: This week in podcasts from The Debrief, hosts MJ Banias and Stephanie Gerk tell us all about robot dogs and oblong space object detections in the latest installment of The Debrief Weekly Report. Meanwhile, on The Micah Hanks Program this week, I’m joined by my cofounder Tim McMillan for a discussion of excessive secrecy in government, along with statements about classification by Director of National Intelligence Avril Haines.

Video News: Be sure to catch Chrissy Newton’s recent chat with scientist Carmel Majidi on Rebelliously Curious, who explains how a shapeshifting metal robot he created can escape from jail, just like a scene out of Terminator 2: Judgement Day. You can also watch past episodes and other great content from The Debrief on our official YouTube Channel.
And with that, it’s time to shift our focus over to what recently turned up in the analysis of asteroid samples conducted by an international team and why it could help us understand the origins of life on Earth.
NASA Team Completes Its Asteroid Sample Analysis
A NASA analysis of samples returned to Earth from the surface of an asteroid by a Japanese spacecraft has revealed the presence of rich organic molecules, lending weight to theories involving the chemical precursors to life on Earth originating in space.
According to an analysis by the American space agency and its international partners, initial samples retrieved from asteroid Ryugu by the Japanese Hayabusa2 spacecraft found an abundance of organic molecules, suggesting that the components necessary for life could have been introduced in Earth’s distant past from such celestial sources.
Such concepts have their origins as far back as the 5th century BCE when Greek scholar Anaxagoras proposed a philosophical precursor to the modern idea that objects in space like asteroids and comets could potentially be carrying the seeds of life.
Consisting primarily of oxygen, nitrogen, hydrogen, and sulfur or other atoms combined with carbon, organic molecules can be produced from a variety of chemical reactions, not all of which involve life. This fact has intrigued proponents of off-planet origins for these building blocks of life, since almost every living organism on our planet owes its origins to combinations of these molecules.
Extraterrestrial Origins of Life on Earth?
Of key significance in the recent analysis was the detection of several amino acids used by organisms on Earth to build proteins, along with organic substances like aliphatic amines, polycyclic aromatic hydrocarbons, carboxylic acids, and heterocyclic compounds rich in nitrogen that all form in the presence of another component that is vital to the formation of life: liquid water.
These prebiotic molecules, meaning they are the chemical precursors of life, and their discovery in samples collected on the surface of Ryugu, is significant because it reveals that such key ingredients to life could be shielded against the extreme conditions that occur in space, allowing them to transit great distances and potentially make their way to planets like Earth, where the processes that lead to the formation of life can take place.
“These molecules can be transported throughout the solar system, potentially dispersing as interplanetary dust particles after being ejected from the uppermost layer of the asteroid by impacts or other causes,” said Hiroshi Naraoka of Kyushu University, Fukuoka, Japan in a statement.
Building Blocks of Life
According to the international team, who have recently published a paper on their findings, the compounds detected in the samples harvested from asteroid Ryugu appear to be consistent with what has already been found in meteorites that have been exposed to water where it is suspected of existing in space.
Although the presence of organics in the Ryugu samples is promising, the presence of other components vital to the formation of life, such as sugars and nucleobases required in the formation of RNA and DNA, have not been detected yet in the current samples.
“It is possible these compounds are present in asteroid Ryugu,” said Daniel Glavin of NASA Goddard Space Flight Center in a statement, noting that the compounds in question “are below our analytical detection limits given the relatively small sample mass available for study.”
Going forward, additional samples will be studied in the years ahead, which will include comparisons between samples from asteroid Ryugu and another asteroid, Bennu, once samples from it are returned to Earth later this year by NASA’s OSIRIS-Rex mission.
With the volume of the sample collection expected from Bennu, NASA and its international partners also believe it could provide even better opportunities to search for evidence of components that may help shed further light on the organic composition of asteroids, as well as the role they might have played in the mysterious origins of life on Earth.
