NASA spacecraft on way to asteroid to bring back samples

CAPE CANAVERAL, Fla. — The first NASA explorer of its kind took off on a seven-year quest Thursday, chasing after a big, black, unexplored asteroid to gather a few handfuls of gravel for return to Earth.
These bite-size bits of ancient space rock from asteroid Bennu could hold clues to the origin of life, not just on our planet but potentially elsewhere in the solar system.
Thousands gathered to witness the evening launch of Osiris-Rex, a robotic hunter that looks something like a bird with its solar wings. The spacecraft took flight atop an Atlas V rocket, which soared a little before sunset on the mission, a U.S. first.
Victory was declared an hour later; launch controllers shook hands and embraced as the spacecraft shot out of Earth’s orbit, bound for Bennu.
“Tonight is a night for celebration. We are on our way to an asteroid,” said NASA’s chief scientist, Ellen Stofan. After all, “we’ve just done something amazing.”
“We got everything just exactly perfect,” added Osiris-Rex chief scientist Dante Lauretta of the University of Arizona. “It was an amazing evening for me and for this team.”
It will take two years for Osiris-Rex to reach Bennu (BEHN’-oo), which is circling the sun in a slightly wider orbit than Earth’s. The boxy spacecraft will actually go into orbit around the asteroid, seeking out the best spot before going in for a quick bite.
Round trip, the SUV-sized spacecraft will travel more than 4 billion miles (6 1/2 billion kilometres) by mission’s end in 2023.
NASA has gone after comet dust and solar wind particles before, but never anything from an asteroid. It promises to be the biggest cosmic haul since the Apollo moon rocks.
The roundish rock — an estimated 1,600-plus feet (500 metres) across and taller than the Empire State Building — is believed to harbour carbon dating back 4.5 billion years, to the beginning of our solar system. That makes it a time capsule and a scientific prize.
“We will make discoveries on this mission that we have not anticipated. It’s exciting!” said Bill Nye, “The Science Guy,” chief executive officer of the Planetary Society.
The launch came 50 years to the day that the first “Star Trek” episode aired on TV. NASA launch commentator Mike Curie referenced the anniversary, urging the spacecraft at liftoff “to boldly go” to Bennu and back. This is yet another example of NASA “turning science fiction into science fact,” Stofan noted.
Osiris-Rex may lead to asteroid-mining missions, according to scientists, and could help protect the planet from menacing space rocks.
Japan already has visited an asteroid and returned some specks (the mission didn’t go quite as planned), and is chasing another space rock for even more samples. Osiris-Rex’s bounty, however, should surpass that; Lauretta and his team want at least 60 grams of dust and gravel, or 2 ounces’ worth when the big day comes in 2020. Ground tests have yielded eight times that in a single scoop, so hopes are high for four to five handfuls.
Osiris-Rex will hover like a hummingbird over Bennu, according to Lauretta, as the spacecraft’s 10-foot (3-meter) mechanical arm touches down like a pogo stick on the surface for three to five seconds. Thrusters will shoot out nitrogen gas to stir up the surface, and the loose particles will be sucked up into the device. Spacecraft managers call it “the gentle high five.” They get just three shots at this, before the nitrogen gas runs out and the effort abandoned.
The team opted for this touch-and-go procedure instead of landing to increase the odds of success. Despite extensive observations of Bennu from ground and space telescopes, no one knows exactly what to expect there, and it could be difficult if not impossible to anchor a spacecraft on the surface, Lauretta said.
Osiris-Rex’s freed sample container — the same kind used for the comet-dust retrieval — will parachute down with the pristine asteroid treasure in Utah. The mother spacecraft, meanwhile, will continue its orbit of the sun.
Among the 8,000 NASA launch guests was the schoolboy who came up with the asteroid’s name for a contest.
Twelve-year-old Mike Puzio of Greensboro, North Carolina, cheered as he watched his first up-close rocket launch: “It was awesome!”
“Unbelievable,” added Dr. Larry Puzio, his pediatrician dad.
The name Bennu comes from the heron of Egyptian mythology. Mike thought Osiris-Rex looked like a bird, with its twin solar wings and long arm outstretched for a sample grab. And with the spacecraft named after the Egyptian god Osiris, Bennu was an obvious choice, he said.
Osiris-Rex is also a NASA acronym for origins, spectral interpretation, resource identification, security-regolith explorer. The estimated cost of the mission is more than $800 million.
“Space exploration brings out the best in us,” Nye said shortly before Osiris-Rex began its journey. “It is an extraordinary use of our intellect and treasure to elevate humankind, to help us know our place in the cosmos.”
It may also one day save the home planet.
Bennu swings by Earth every six years, and 150 years from now, could hit us. The odds are less than one-tenth of 1 per cent, according to Lauretta. While this particular rock won’t destroy Earth — just carve out a huge crater — other asteroids could cause more trouble.
Osiris-Rex will help scientists better understand the ever-changing paths of asteroids, and that could prove its biggest payoff.

Astronomers have misconception about the Asteroids; therefore:
This spacecraft cannot circle around this Asteroid: why because this relatively small asteroid (about 500 meters wide) which is cold having no heat in its core, and so it has no gravity.The thing it can do .. it will pass beside it, and to hurl some instrument to collide with it, like what had happened in the past in what was called The Deep Impact.

In addition, the spacecraft or the probe cannot settle on the surface of this Asteroid Bennu, for the same reason, and if it settles it cannot then return back to Earth.

Therefore, it is designed to pass by it and to return back with some information to the Earth.

Didn't they make a movie about this a few years ago? Don't want to spoil it but it didn't work out very well.

There might have been some movie; they made movies for so many subjects
The free food for the poor is very good; but the scientific research is also mandatory.

The important thing is to make use of such robotic journey in the best way: they are misguided to the true fact about Asteroids, their origin and their nature:

1- They say the asteroids are very old and give the explanation about the formation of the solar system, while they have no such relation; they were a planet that had been destroyed.
2- They think the asteroids circle around the Sun, while in fact they circle around the planets especially Mars and Jupiter: when the orbit of Phytone: the planet of the Asteroids was situated between the orbits of Mars and Jupiter.
3- Astronomers cannot distinguish clearly between the Asteroids, the comets and the meteorites.

That is an an $800M school.

Hooray for geologists with rockets!

There are various ways asteroids were created. Some come from destruction of potential planets, some from meteor impacts on planets that were not destroyed. Either way they are far older than we are and we might learn something which you admit is a good thing.

There are millions of observable asteroids and most circle the sun. This has been observed for a few hundred years and in the technological age they have tracked thousands of them for many years and know exactly what the orbits are.

Of course they can. It has to do with composition and orbit and entry into Earth's atmosphere.

Heat has no bearing on gravity. It is determined by the mass of an object. I'm not sure if they can create an orbit around such a small object but I would suppose if the mass was great enough they could. It is also possible to use another object of greater mass to affect a course change and create an orbital trajectory. I'm not involved and haven't seen the math so I cannot say but it is possible.

If they have enough propulsion they can theoretically land and then return. Given it is unmanned and they are not concerned with how long it takes to return it is quite possible, it is just going to take a long time at such a low velocity.
Quote:

Or land and return over a long time-frame as pointed out above.

You probably shouldn't try to put an ancient book of questionable validity up against modern math and science.

Gravity is mostly responsible for the heat at the core of a heavenly body as it compresses and "rubs" the matter together at towards the center. Gravity creates the heat. Heat does not create the gravity.

Islamic "Science" ...

Yer right, electromagnetism creates gravity and heat at the same time. They found no Bosons at Cern and no gravity either as a matter of facts so far they've discovered how to keep the pigeon shjt from shorting out the big expensive magnets and nothing else they've published. The whole complex is a science asylum, they have no relativity. you can't even see any bottles of quagmires they've captured, no hardons aether. 90 billion down the black hole not counting the drugs and booze. I'd love to work there as a janitor or elevator mechanic. It must be funny when they pigeons attack.

If this asteroid is as dark as they say it is, it might be covered in graphite ... Bucky Balls of Carbon. That is likely why they chose this one.

You can derive Amino Acids from that and a few other bits ...

Graphite can also be conpressed into diamonds! Check out those little impact craters!

They should concentrate on the kind that just miss us a lot lately. There was a lot of talk in history about rains of little stars. Mythology remembers the bright light and the thunder and the floods of rats and pestulance fire ash. Climate change you can count on.

I agree, basics, we can't go back, so charge in the other direction, give them trades instead of trade, without trades you can't.

They are worthless are thgey not, are you suggesting we might foist damaged good on some unsuspecting customers? No all are stuff should be solid wood. That's where this countrys future is. tables spoons etc,


Basic.

Saskacthchewon should be reforested.

Some trees like to grow in tar sands, very nice wood.

Made of oil.

Big asteroid already got the dragons around here. Lots of dragon bones lying around in Saskatchewan, though.
