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.
Readers!
Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.

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?
