Washington, Sep 22 : NASA’s asteriod hunting spacecraft OSIRIS-REx , is all set to make a close flyby of Earth on Friday, before reaching asteroid Bennu, media has reported.

The Earth’s gravity will fling the OSIRIS-REx spacecraft, travelling at a staggering speed of 19,000 miles (30,758 km) per hour, upward by about six degrees so that its trajectory will match the tilt of the orbit of asteroid Bennu, nytimes.com reported on Thursday.

OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer) was launched atop a United Launch Alliance Atlas V 411 rocket on September 8, 2016 to study samples from the asteroid Bennu — a type B carbonaceous asteroid with an approximate diameter of about 1,614 feet (492 meters).

On Friday, the spacecraft will approach and retreat from its closest position over Earth, approximately 11,000 miles (17,000 km) above the planet’s surface, swinging it over Australia before making its closest approach over Antarctica near Cape Horn, Chile.

“The opportunity to capture images of the OSIRIS-REx spacecraft as it approaches Earth provides a unique challenge for observers to hone their skills during this historic flyby,” Dante Lauretta, OSIRIS-REx principal investigator at the University of Arizona, Tucson, NASA said in a statement earlier this month.

“We’re essentially stealing a bit of the Earth’s momentum as we go by,” said Michael Moreau, who leads Osiris-Rex’s navigation team at NASA’s Goddard Space Flight Center in Greenbelt.

The spacecraft is scheduled to arrive at its destination of Bennu in 2018, where it will collect and return samples that experts believe may hold the building blocks of life.

The Academy of Television Arts and Sciences (ATAS) has nominated NASA’s Jet Propulsion Laboratory (JPL) for Outstanding Original Interactive Program for its coverage of the Cassini mission’s Grand Finale at Saturn.

The Primetime Emmys will be awarded by the ATAS in Los Angeles on September 17.

The Creative Arts Emmys, which include interactive awards, will be presented during a separate ceremony on September 15 at the Microsoft Theatre in Los Angeles, NASA said in a statement on Friday.

In 2017, after nearly 20 years in space and 13 years revealing the wonders of Saturn, NASA’s Cassini orbiter was running out of fuel. As a final act, Cassini began a whole new mission — its Grand Finale, where it journeyed into the unknown and ended with a spectacular plunge into the planet.

Cassini’s first, daring dive into the unexplored space between the giant planet and its rings kicked off the campaign on April 26 in 2017.

It culminated on September 15, 2017, with live coverage of Cassini’s plunge into Saturn’s atmosphere, with the spacecraft sending back science to the very last second.

JPL created a multi-month digital campaign to celebrate the mission’s science and engineering accomplishments and communicate why the spacecraft must meet its end in the skies of Saturn.

The multi-faceted campaign included regular updates on Twitter, Facebook, Snapchat, Instagram and the Cassini mission website, multiple live social, web and TV broadcasts during which reporter and public questions were answered.

The Emmy Awards nominations have turned out to be more diverse than last year. Fantasy drama “Game of Thrones” has earned 22 nominations for the coveted Awards, while HBO’s 17-year streak as the most nominated network has been broken by Netflix. (IANS)
