Spaceboards contain small binds Binding, breaking record Space

Yesterday – although many of the Earth were heard in the & # 39; New Year – NASA's NASA spacecraft was 70 million miles (110 million km) away; break a spell check record. The OSIRIS-REx NASA vessel made one burn, eight, despite its gutters and went into an orbit around an asteroid near the Land Bennu, and Determine the smallest thing despite a spacecraft still. And Bennu, indeed, is very small. There is a medium diameter of about 1,614 feet (0.306 miles, 492 meters). The stream was held on December 31, 2018, at 18:43 PM UTC (2:43 p.m. EST). Dante Lauretta, OSIRIS-REx headquarters inspector at Tucson University of Arizona, said:

The team [performed] move completely on the orbit. With the closing of the addressing campaign, we look forward to the scientific mapping and the extent of a sample selection of the mission.

He said:

Getting in to the orbit around Setting an amazing thing is that our team has been going to & # 39; planning for years.

A report from the team said that Bennu – was named for the creation, and revival of an ancient Egyptian mythical bird associated with the sun – which has no difficulty in keeping a vehicle in an orbit stables.

The registrar was the password; formerly for the closest order of the planetary body of the Rosetta spacecraft around four miles (6.4 km) from the 67P / Churyumov-Gerasimenko mid comet in May 2016. OSIRIS-REx is closer to Setting a mile (1.6 km) from the center. This distance is essential to lock the spacecraft to Bennu, said space sciences said, because the problem of Bennu is only five million people as strong as Earth.

The spacecraft is regularly circulated through February at 62 hours per hour.

A dynamics system manager on OSIRIS-REx, Mike Moreau, based at NASA's Space Flight Giotard Center in Greenbelt, Maryland:

Our orbit design is highly dependent on Bennu's physical features, such as the vast and deep range, which we did not know before we reached.

So far, we need to report to a wide range of settings that may exist in our computing symbols to ensure that we move to the spacecraft as close to Bennu. As the team learned more about the asteroid, we put in new information to enter the & # 39; last picture.

Although OSIRIS-REx is in the most stable round; It may be possible, the team said that there is a harsh fix. Determine the urgent need for some changes to keep the space space safe. Dan Wibben, shipment planning director and OSIRIS-REx at KinetX Aerospace in Simi Valley, California said:

The liability of Determination is so small, forces such as solar radiation and thermal stress from the surface Determine that they become much more relevant and can be done; pushing her sparrow around her in her orbit much larger than he was; move across Earth or Mars, where the division is the most strongest force.

An essential goal of this orbital level, the team said, that they will get better treatment of most of their products; attack and award-winning award, features that influence the planning of the mission, especially the short result on the surface for a sample collection in 2020. In a Determining case, scientists can not measure these features but by obtaining OSIRIS-REx closely to the surface to see how it is; motion is bent from the important Bennu draw.

The OSIRIS-REx mission is scheduled to deliver the sample to Earth in September 2023.

A Bass Asteroid is considered to be a hazardous factor because the orbital is being carried close to Earth and it is large enough to make a major damage if it is affected. It has a 1-in-2,700 comprehensive opportunity to affect Earth between 2175 and 2199.

Below: the OSIRIS-REx spa boat was successful for burning on December 31, 2018, at 18:43 AM UTC (2:43 pm EST) and so it went into an orbit around a sea distance Determining near on Earth. The move is to Determine the smallest thing that is still started by a spacecraft.
