A pick-pocketed piece of an enormous asteroid named Bennu is on its manner again to Earth. NASA’s Osiris-Rex is winding down its mission greater than seven years after launching from Cape Canaveral, Florida.
Again in 2020, the van-size spacecraft carried out a “touch-and-go” maneuver — type of like a chest bump in area — and swiped a number of ounces of fabric from the area rock, which is known as a pile of rubble held collectively by its personal gravity. Osiris-Rex lingered round Bennu till 2021, when it began its two-year journey again to Earth.
The lengthy flight ends on Sept. 24, when the spacecraft will jettison the capsule containing the pattern. The capsule will then make a superheated journey by the environment earlier than parachuting in for a comfortable touchdown on the US army’s Utah Take a look at and Coaching Vary close to Dugway, Utah.
Mission controllers have been getting ready for the capsule’s return for months now. On Sept. 10, NASA reported the spacecraft briefly fired its thrusters to level itself towards Earth. The minor adjustment places Osiris-Rex on track to launch the capsule on a trajectory to enter our environment off the coast of California at 7:42 a.m. PT. About 13 minutes later it would contact down southwest of Salt Lake Metropolis someplace in a predetermined space measuring 36 miles by 8.5 miles throughout.
This graphic reveals the occasions that occur between the time the Osiris-Rex spacecraft releases its pattern capsule to the time it lands within the Utah desert.

The capsule will sizzle because it races by the sky protected by a warmth protect. Will probably be tracked with thermal imaging gear and restoration groups will probably be deployed by helicopter to get well it as fast as attainable to keep away from attainable contamination from Earth’s setting.
Osiris-Rex is the primary such mission led by NASA. Japan’s area company efficiently despatched two spacecraft, named Hayabusa and Hayabusa2 to gather and return samples from asteroids Itokawa and Ryugu, respectively.
The pattern is about to reach at Johnson House Middle in Houston after touchdown on Sept. 24, the place it would bear preliminary evaluation and be unveiled on Oct. 11 in a livestreamed information convention. It is hoped the pattern will present scientists with a window into the start of the photo voltaic system, together with the solar and planets, some 4.5 billion years in the past.
As for the primary spacecraft, it is not achieved. After sending its treasure to the floor, Osiris-Rex will fireplace its engines to keep away from smashing into the environment itself. As a substitute, it would proceed on to its subsequent goal, the asteroid Apophis, at which level it is going to be re-christened Osiris-Apex (Osiris-Apophis Explorer). The car is not outfitted to gather and return one other pattern, however it might attempt to blast the asteroid with its fuel thrusters in an try and dislodge mud and different small bits for examine.
Apophis is a vital goal as a result of it is thought of a probably hazardous asteroid. Whereas any likelihood of it impacting Earth within the subsequent century has been dominated out, it is going to be value retaining an in depth eye on for hundreds of years to return.
