CAPE CANAVERAL: After a two-year chase, a NASA spacecraft arrived Monday at the ancient asteroid Bennu, its first visitor in billions of years.
The robotic explorer Osiris-Rex pulled within 12 miles (19 kilometers) of the diamond-shaped space rock. It will get even closer in the days ahead and go into orbit around Bennu on Dec. 31. No spacecraft has ever orbited such a small cosmic body.
It is the first US attempt to gather asteroid samples for return to Earth, something only Japan has accomplished so far.
Flight controllers applauded and exchanged high-fives once confirmation came through that Osiris-Rex made it to Bennu — exactly one week after NASA landed a spacecraft on Mars.
“Relieved, proud, and anxious to start exploring!” tweeted lead scientist Dante Lauretta of the University of Arizona. “To Bennu and back!“
With Bennu some 76 million miles (122 million kilometers) away, it took seven minutes for word to get from the spacecraft to flight controllers at Lockheed Martin in Littleton, Colorado. The company built the spacecraft there.
Bennu is estimated to be just over 1,600 feet (500 meters) across. Researchers will provide a more precise description at a scientific meeting next Monday in Washington.
About the size of an SUV, the spacecraft will shadow the asteroid for a year, before scooping up some gravel for return to Earth in 2023.
Scientists are eager to study material from a carbon-rich asteroid like dark Bennu, which could hold evidence dating back to the beginning of our solar system 4.5 billion years ago. As such, it’s an astronomical time capsule.
A Japanese spacecraft, meanwhile, has been hanging out at another near-Earth asteroid since June, also for samples. It is Japan’s second asteroid mission. This latest rock is named Ryugu and about double the size of Bennu.
Ryugu’s specks should be here by December 2020, but will be far less than Osiris-Rex’s promised booty.
Osiris-Rex aims to collect at least 60 grams, or 2 ounces, of dust and gravel. The spacecraft won’t land, but rather use a 10-foot (3-meter) mechanical arm in 2020 to momentarily touch down and vacuum up particles. The sample container would break loose and head toward Earth in 2021.
The collection — parachuting down to Utah — would represent the biggest cosmic haul since the Apollo astronauts hand-delivered moon rocks to Earth in the late 1960s and early 1970s.
NASA has brought back comet dust and solar wind particles before, but never asteroid samples. Japan managed to return some tiny particles in 2010 from its first asteroid mission , also named Hayabusa.
Both Bennu and Ryugu are considered potentially hazardous asteroids. That means they could smack Earth years from now. At worst, Bennu would carve out a crater during a projected close call 150 years from now.
Contact with Bennu will not significantly change its orbit or make it more dangerous to us, Lauretta stressed.
Scientists contend the more they learn about asteroids, the better equipped Earth will be in heading off a truly catastrophic strike.
The $800 million Osiris-Rex mission began with a 2016 launch from Cape Canaveral, Florida. Its odometer read 1.2 billion miles (2 billion kilometers) as of Monday.
Both the spacecraft and asteroid’s names come from Egyptian mythology. Osiris is the god of the afterlife, while Bennu represents the heron and creation.
Osiris-Rex is actually a NASA acronym for origins, spectral interpretation, resource identification, security-regolith explorer.

Policewoman honored for soothing crying baby when her mother fell unconscious at Beirut airport
- ISF honors first adjutant for comforting and feeding baby-milk to scared infant whose mother was rushed to hospital
- Social media users praise policewoman for her ‘humane and empathetic’ act after photos went viral
BEIRUT: A Lebanese policewoman who comforted an infant and fed her milk while her mother was hospitalized after falling unconscious at Beirut airport was honored for what social media users dubbed a ‘humane and empathetic’ act.
First Adjutant Nadia Nasser was on duty when the unidentified baby’s mother suffered a sudden illness and fell unconscious at a checkpoint inside Beirut International Airport earlier this month.
Photos of Nasser holding the months-old baby in her arms, preparing a milk bottle and feeding her went viral across social media, where users described the policewomen’s act as ‘motherly, compassionate and humane’ behavior.
Brig. Gen. Moussa Karnib of Lebanon’s Internal Security Forces honored Nasser on Friday for caring for the infant for almost two hours at the airport after her mother was rushed to a hospital.
A media statement said the first adjutant was honored upon the directives of ISF’s Director General Maj. Gen. Raed Abdullah, after she took personal initiative on Feb. 2 to comfort the infant.
Commenting on Nasser’s photos that went viral, a user called Sami said she should be promoted for her ‘selfless and empathetic’ act.
Another user, Joe, commented: “She should be rewarded.
“This is how loyalty and love for one’s job and country are built,” wrote a user called Youssef.
Media reports said that when the incident happened, the baby’s fear and cries prompted Nasser to take the initiative to comfort and remain beside her until her mother’s condition stabilized.
ISF’s statement did not clarify whether Nasser and the baby accompanied the mother in the ambulance or how they were reunited later.
