Nasa have offered a first glimpse at samples of a 4.5-billion-year-old asteroid which they believe could hold the key to a greater understanding of the origins of life on Earth.
Initial studies of the space rock derived from Bennu – delivered to Earth last month – show evidence of high-carbon content and water, Nasa said on Wednesday.
Nasa Administrator Bill Nelson said the findings from a seven-year mission in space “will help scientists investigate the origins of life on our own planet for generations to come”.
The Osiris-Rex spacecraft flew close to Earth to drop a capsule carrying 250g of soil from the asteroid on September 25.
Scientists are expected to analyse the celestial discovery for decades to come, helping to unravel the mysteries of how our solar system was formed.
“Our labs were ready for whatever Bennu had in store for us,” said Vanessa Wyche, director of Johnson Space Centre.
“We’ve had scientists and engineers working side-by-side for years to develop specialised gloveboxes and tools to keep the asteroid material pristine and to curate the samples so researchers now and decades from now can study this precious gift from the cosmos.”
Scientists say early forensic investigations of the asteroid have already reaped impressive results.
“The bounty of carbon-rich material and the abundant presence of water-bearing clay minerals are just the tip of the cosmic iceberg,” said Dante Lauretta, Osiris-Rex principal investigator at the University of Arizona.
“These discoveries, made possible through years of dedicated collaboration and cutting-edge science, propel us on a journey to understand not only our celestial neighbourhood but also the potential for life’s beginnings.
“With each revelation from Bennu, we draw closer to unravelling the mysteries of our cosmic heritage.”
The mission team will continue painstaking analysis of the samples for the next two years, with the support of more than 200 scientists from across the globe.
How did the Osiris-Rex secure samples?
Bennu is a near-Earth asteroid that was first discovered in 1999 and is said to be formed from materials that date back billions of years.
The sample collection was a complex process because there was an 18.5-minute delay in sending and receiving signals between mission control and the craft due to the distance.
Navigation cameras on the capsule helped it to successfully reach the asteroid.
Bennu orbits the sun at 101,388kph. Osiris-Rex was programmed to travel towards it at about 19,400kph and slow itself down on approach.
Once close enough, the spacecraft extended its robotic arm and obtained samples.
How did the craft deliver the asteroid soil back to Earth?
After travelling billions of kilometres to Bennu and back, the spacecraft released its sample capsule towards Earth’s atmosphere.
The spacecraft was 102,000km from Earth’s surface at the time – about one-third of the distance from Earth to the Moon.
The capsule entered the atmosphere at 6.42pm while travelling at 27,650km and, within 10 minutes, it landed on a military range in a Utah desert.
Two parachutes that deployed helped to stabilise and slow the capsule down.

FFP EXPLAINED
What is Financial Fair Play?
Introduced in 2011 by Uefa, European football’s governing body, it demands that clubs live within their means. Chiefly, spend within their income and not make substantial losses.
What the rules dictate?
The second phase of its implementation limits losses to €30 million (Dh136m) over three seasons. Extra expenditure is permitted for investment in sustainable areas (youth academies, stadium development, etc). Money provided by owners is not viewed as income. Revenue from “related parties” to those owners is assessed by Uefa's “financial control body” to be sure it is a fair value, or in line with market prices.
What are the penalties?
There are a number of punishments, including fines, a loss of prize money or having to reduce squad size for European competition – as happened to PSG in 2014. There is even the threat of a competition ban, which could in theory lead to PSG’s suspension from the Uefa Champions League.

Common OCD symptoms and how they manifest
Checking: the obsession or thoughts focus on some harm coming from things not being as they should, which usually centre around the theme of safety. For example, the obsession is “the building will burn down”, therefore the compulsion is checking that the oven is switched off.
Contamination: the obsession is focused on the presence of germs, dirt or harmful bacteria and how this will impact the person and/or their loved ones. For example, the obsession is “the floor is dirty; me and my family will get sick and die”, the compulsion is repetitive cleaning.
Orderliness: the obsession is a fear of sitting with uncomfortable feelings, or to prevent harm coming to oneself or others. Objectively there appears to be no logical link between the obsession and compulsion. For example,” I won’t feel right if the jars aren’t lined up” or “harm will come to my family if I don’t line up all the jars”, so the compulsion is therefore lining up the jars.
Intrusive thoughts: the intrusive thought is usually highly distressing and repetitive. Common examples may include thoughts of perpetrating violence towards others, harming others, or questions over one’s character or deeds, usually in conflict with the person’s true values. An example would be: “I think I might hurt my family”, which in turn leads to the compulsion of avoiding social gatherings.
Hoarding: the intrusive thought is the overvaluing of objects or possessions, while the compulsion is stashing or hoarding these items and refusing to let them go. For example, “this newspaper may come in useful one day”, therefore, the compulsion is hoarding newspapers instead of discarding them the next day.
