NASA probe leaking asteroid samples after hearty collection

WASHINGTON, D.C. (Reuters) - The U.S. probe that collected a sample from an asteroid earlier this week retrieved so much material that a rock is wedged in the container door, allowing rocks to spill back out into space, NASA officials said on Friday.

 

The robotic arm of the probe, OSIRIS-REx, on Tuesday night kicked up a debris cloud of rocks on Bennu, a skyscraper-sized asteroid some 200 million miles (320 million km) from Earth and trapped the material in a collection device for the return to Earth.

 

But images of the spacecraft's collection head beamed back to ground control revealed it had caught more material than scientists anticipated and was spewing an excess of flaky asteroid rocks into space.

 

The leakage had the OSIRIS-REx mission team scrambling to stow the collection device to prevent additional spillage."Time is of the essence," Thomas Zurbuchen, NASA’s associate administrator for science, told reporters. Zurbuchen said mission teams will skip their chance to measure how much material they collected as originally planned and proceed to the stow phase, a fragile process of tucking the sample collection container in a safe position within the spacecraft without jostling out more valuable material.NASA will not know how much material it collected until the sample capsule returns in 2023. The troubleshooting also led mission leaders to forgo any more chances of redoing a collection attempt and instead commit to begin the spacecraft’s return to Earth next March. "Quite honestly, we could not have performed a better collection experiment," OSIRIS-REx principle investigator Dante Lauretta told reporters, affirming a hearty sample size.

 

But with the door lodged open by a rock and the "concerning" images of sample spillage, "we're almost the victim of our own success here," he added. The roughly $800 million, minivan-sized OSIRIS-REx spacecraft, built by Lockheed Martin, launched in 2016 to grab and return the first U.S. sample of pristine asteroid materials. Japan is the only other country to have accomplished such a feat.Asteroids are among the leftover debris from the solar system’s formation some 4.5 billion years ago. A sample could hold clues to the origins of life on Earth, scientists say.

"Honey, I'm gonna pull over and check the trunk. Seems I didn't shut it all the way"

I do wonder how bits of sample could fly out of container (...spewing an excess of flaky asteroid rocks into space). Must be the wind.... ????????

Well, we could wait a 100 years or so. In the past Bennu had a 1 in 24,000 chance of hitting Earth and now for the year 2160 (or there about) it has 1 in 2,700. So if the chances keep rising like that we'll have a 500 wide meter sample 'right in our own back yard'.

Is it too much to say that 800 million could be better spent back here?

More important to invest in where we are heading, not where we 'might' have come from.

 

 

Let’s find out what bountiful metals that can help mankind

And there is the classic cause and effect of greed.
"Pack it full, pack if full!!!"
With a compromised bay it will probably burn up on reentry if it even makes it back.
"But we packed if full!!!"
