NASA’s Osiris-Rex spacecraft On Tuesday it will briefly contact a giant planet and drop some rocks and dust from its surface to return to study Earth. Event mark a Major first for NASA And a potential boon to our understanding of science, space exploration and the solar system. Lockheed Martin Space Adventure will broadcast the mission live, and we have everything you need to know about how the mission will unfold and how it will unfold.
Touch-and-go, or TAG, is a sample collection of ships 101955 Benu Landing is scheduled for Tuesday, October 20, at 3:12 p.m. NASA TA And. And will broadcast the tricks live Agency website Starting Tuesday at 2 p.m. You can find the live broadcast link below.
When did the mission begin?
Osiris-Rex has existed as a concept since at least 2004, when a team of astronomers first proposed the idea to NASA. After more than a decade of development, the spacecraft Launched September 8, 2016 in Cape Canaveral, Florida, Atlas V rocket tops from United Launch Alliance, a joint venture between Lockheed Martin and Boeing. The spacecraft spent the next 26 months traveling to Benu, officially arriving on December 3, 2018.
Since then, the mission team has spent nearly two years traveling through the diamond-shaped space rock, surveying and mapping it to choose its best location. In recent months, rehearsals have begun before attempts to collect incoming samples, and now the team says it is ready to play TAG with Benu.
Why Benu?
Benu is the so-called “wreckage of the wreckage”, meaning it was formed in the deep cosmic past when gravity slowly forced the remnants of an ancient collision to gather. The result is something like a body-shaped object, like a spinning top, about a third of a mile (500 meters) in diameter, and a surface filled with large boulders and boulders.
Benu is considered to be a window into the past of the solar system: an ancient, carbon-rich body that carries the building blocks of both planet and life. Some of these resources, such as water and metals, could be mined for future use on Earth or in space exploration.
Another feature of the ship that makes it particularly interesting to scientists and humans in general is that it has a chance to affect the Earth in the distant future. Turned on List of NASA impact risks, Benu has been rated No. 2. The current figures show dozens of potential effects in the last quarter of the 22nd century, although all have a minute’s chance to actually go through.
How will TAG work?
For anyone who has ever been involved with robots or may have even entered a robotics competition, the Osiris-Rex mission seems like the ultimate dream come true for a young robotist. The touch-and-go sampling process is a complex, high-stakeholder task that has been setting a significant milestone for years. If successful, it will play a role in history and our future in space.
The plan is for Osiris-Rex to touch a rock on the Bannu. Landing site Dieted Nightingale. The van-sized spacecraft is just as large as a transparent space that would need to interact with building-sized boulders around the landing area to touch a relatively clean space. However, the arm of a robotic specimen will be the only part of the Osiris-Rex that will actually be placed on the surface. One of the three pressurized nitrogen canisters will ignite a fire to ignite a sample of dust and small rocks that can then be caught in the head of an arm collector to deliver safely and return to Earth.
It will take about four hours to reach the surface of Benu, about the time it takes for the storm to form a complete revolution. After this slow approach, the actual TAG sampling process is significantly less than 16 seconds.
Preparations for the TAG have not been as planned. The mission’s management initially expected that Benu’s surface would have significantly more potential landing spots, mainly covered with a comparatively better material than sand or gravel. This shows that Benu’s surface is very rough and was not welcomed.
After spending a lot of time evaluating the mission over the past two years, the team decided to try “threading the needle” through the border-filled landscape at Nightingale and some other backup sample sites. It is still possible that the surface will be too rocky to get the best sample. If this happens, the team may choose to try again on a different site. Osiris-Rex is equipped with three nitrogen cones to ignite and degrade the surface, which means the team makes three attempts to capture a specimen.
What then?
Immediately after collecting its samples, Osiris-Rex will set fire to its thrusters to retreat from Benu. The spacecraft will continue to climb Bannu for the rest of 2020 before embarking on a two-year voyage to return to Earth next year.
On September 24, 2023, Osiris-Rex plans to launch its sample return capsule Jetisson, which will land in the Utah Desert and be retrieved for study.
Wasn’t this done before?
Yes. Japan’s Hayabusa spacecraft successfully returned small grains Star 25143 Itokawa Its successor, Hayabusa-2, In 2019, Hurricane Katrina fired a special copper bullet at Ryugu And then got some shrapnel. That specimen is returning to earth.
