|WASHINGTON ECCO Irving Slip On 511524-02001 Black , Sept. 22 (Xinhua) -- NASA's asteroid-bound OSIRIS-REx spacecraft made a close approach to Earth and successfully used our planet's gravity on Friday to "slingshot" itself on a path toward the asteroid Bennu, the U.S. space agency said.
The Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer (OSIRIS-REx) spacecraft came within 10,711 miles (17 ECCO Jack Slip On 504034-02001 Black ,237 km) of Antarctica, just south of Cape Horn, Chile, at 12:52 p.m. EDT (1652 GMT), NASA said in a statement.
As a result of the flyby, the velocity change to the spacecraft was 8 Men'S ECCO Leather Slip On 615215 Black ,451 miles per hour (3.778 km per second).
"The total velocity change from Earth's gravity far exceeds the total fuel load of the OSIRIS-REx propulsion system," said Rich Burns, OSIRIS-REx project manager at NASA's Goddard Space Flight Center.
"So we are really leveraging our Earth flyby to make a massive change to the OSIRIS-REx trajectory, specifically changing the tilt of the orbit to match Bennu."
The OSIRIS-REx spacecraft, launched in 2016, is currently on a seven-year journey to rendezvous with ECCO Mens Intrinsic 2 Slip On 860504-51707 Black , study, and return a sample of Bennu to Earth.
If all goes well, it will arrive in August 2018 and spend the next two years photographing and mapping the asteroid's surface to better understand its chemical and mineralogical composition, including selecting the sample site.
Then, in July 2020, it will touch the asteroid for only three seconds to collect at least 60 grams of loose rocks and dust using a special device and store the material in a sample return capsule.
The spacecraft will depart the asteroid in March 2021 and travel for two-and-a-half years on a trajectory for Earth return in September 2023.
UNITED NATIONS ECCO Collin Casual Slip On 535584-51707 Black , Sept. 21 (Xinhua) -- Chinese Foreign Minister Wang Yi on Wednesday urged support for the hard-reached Iran nuclear deal and his call was echoed by other major countries.
The Joint Comprehensive Plan of Action (JCPOA), clinched in July 2015 between Iran and the six world powers of Britain, China, France, Germany, Russia and the United States after decade-long negotiations Men'S ECCO Collin 535584 Blue , has helped defuse the Iran nuclear crisis and bolstered the international non-proliferation regime, Wang said.
The agreement is also an important outcome of global governance on security and a beneficial practice of solving a critical issue through political and diplomatic means, Wang said at a meeting of the foreign ministers of the six countries and Iran at the UN headquarters in New York.
While making headway, the implementation of the agreement also faces severe challenges, Wang added, hoping that Wednesday's meeting would send out a positive message of support for the JCPOA and facilitate its implementation.
The Chinese foreign minister said all parties should look at the positive side of the JCPOA as no agreement is perfect. If the pact is discarded ECCO Collin Loafer 535904-02001 Black , the international non-proliferation regime, with the Treaty on the Non-Proliferation of Nuclear Weapons as its bedrock, would be severely impacted and the situation in the Middle East might worsen.
The recent development on the Korean Peninsula demonstrates the significance of the JCPOA, he added.
Wang also hoped that all parties would exercise the right political judgment and create favorable conditions for the implementation of the agreement.
He urged them to discharge their obligations to ensure effective implementation of the deal and solve their differences through dialogue.
China supports the JCPOA and is willing to work to preserve it and continue its participation in the implementation process, he said.
The JCPOA faces the risk of collapse amid a fallout between Washington and Tehran.
In his speech to the UN General Assembly on Tuesday, U.S. President Donald Trump called the agreement "an embarrassment."
In response ECCO Classic Moc 2.0 570904-01072 Coffee , Iranian President Hassan Rouhani said Wednesday that his country will not be the first to violate the agreement, but will respond "decisively and resolutely" to its violation by any party.
"It will be a great pity if this agreement were to be destroyed by rogue newcomers to the world of politics," Rouhani told the UN General Assembly, in a tacit reference to Trump's attack a day earlier.
China's stance was shared by other world powers at the meeting.
Russian Foreign Minister Sergei Lavrov said the Iran nuclear deal was one of the "more important factors of regional and international security."
Germany's Vice Chancellor and Foreign Minister Sigmar Gabriel expressed concerns that if the "the only international example" of nuclear disarmament was discarded, it would be a blow to global efforts to persuade the Democratic People's Republic of Korea to refrain from its nuclear endeavor.

With the amount of different types of handbags available, have you ever wondered how designers and a handbag manufacturer know what type of material to use to produce their handbags?
Handbag manufacturing depends on what you want the handbag to do as to what type of material will be used to make it. Is this design just meant to compliment the outfit of a chic fashionista? Is it meant to glam things up a bit while out on the town, or is it just meant to blend in while being durable and long lasting?
The most common material in handbag manufacturing in this day is le.
