First Bennu asteroid samples recovered from OSIRIS-REx return capsule
Scientists have successfully removed the asteroid samples from the OSIRIS-REx return capsule that the spacecraft obtained from the asteroid Bennu in 2020.
What is more exciting is that though they now have slightly more material than the mission hoped to bring back, they haven’t even opened the capsule’s sample compartment.
The curation team processing NASA’s asteroid Bennu sample has removed and collected 2.48 ounces (70.3 grams) of rocks and dust from the sampler hardware – surpassing the agency’s goal of bringing at least 60 grams to Earth.
And the good news is, there’s still more of NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security–Regolith Explorer) sample to collect.
The sample processed so far includes the rocks and dust found on the outside of the sampler head, as well as a portion of the bulk sample from inside the head, which was accessed through the head’s mylar flap. Additional material remaining inside the sampler head, called the Touch-and-Go Sample Acquisition Mechanism, or TAGSAM, is set for removal later, adding to the mass total.
The large amount of material means there will be plenty to distribute to many scientists for study.
The reason the recovery process is going so slowly is to ensure the samples do not get contaminated by the Earth’s atmosphere. The capsule is inside a glovebox filled with nitrogen. The only way any work can be done is by inserting hands inside gloves that extend into the box. This keeps the samples protected but prevents any direct contact, which makes work slow and difficult.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon. from any other book seller, or direct from my ebook publisher, ebookit.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Edit in last sentence – not quite sure what you wanted to say – maybe “the work must be done inside the box using the gloves to avoid any direct contact.”
?
Andi: The structure of mysentence assumed people know what a glovebox is. I guess I shouldn’t have made that assumption. I will rephrase.
Thanks, Bob, I must admit that when I saw “glovebox”, my first thought was that container in a car that no one keeps gloves in. :)
There was talk of having a mission ready to go in case another visitor pass through our solar system.
A comet heading for the interior which will pass around the sun in 2024 near the orbit of mercury and then exit close to the earth might be a good opportunity for a ice/comet sample?
