Only a few years ago, the conservatives revived one of the latest masterpieces of the Apollo program

Como si fuese una capsule del tempo sellada para la posteridad, una de las últimas muestras lunares de la era Apolo, recolectada durante la misión Apolo 17 Science (ARES) Division of NASA, at the Johnson Space Center, in Houston. It is well preserved and well preserved, alimentary to the permanent geological register of most celestial most close to the Land: the Moon.

In addition to NASA’s return to more of its masters (this is in the El Sur Sur of the Moon with the Artemis missions of the agency), the Apollo Next Generation Sample Analysis Program, of ANGSA, is studying some of the latest lunar samples that NASA has kept intact, in the state of Pristina, waiting for the day when the students will be equipped with methods and innovative technologies for examiners.

“We have the opportunity to open this beautiful opportunity to be guarded by a 50-year-old child,” said Thomas Zurbuchen, administrator of the NASA Science Mission Directorate in Washington. we can see that we are interested in her. ”

El día llegó para la muestra 73001, que primero se prodajo al vacío en la Luna y luego se almacenó en un segundo tubo de vacío exterior protektor dentro de las vitrinas de procesamiento, purgadas con nitrogeno en el labratorio lunar de Johnson. In December 1972, the astronauts Eugene Cernan and Harrison “Jack” Schmitt, read the regular lunar martyrdom of fine cylindrical devices for the collection of specimens, guinea tubes, in an arena deposit in the Taurus-Littrow Capt. of geological history for the fact that the scientific students studied me in detail.

Esta muestra, 73001, es la mitad inferior de un tubo de transmission. The best tube, sample 73002, is located on the Moon in a normal container, without being closed in 2019. The ANGSA research team has been studying its caps of hands and feet, and is anxious to see what happens. the inferior mitad.

The results of the ARES team extruding the 73001 guide tube are realized by extensions at the University of Texas, Austin, using X-ray computed tomography technology, to capture 3D images of high resolution of the composition of the sample inside the tube.

“This is a permanent register of how the material inside the nucleus is exposed and divided into increments of the middle centimeter,” said Ryan Zeigler, conservator of the Apollo masters. “The tube impulsor is very lazy, which is one of the things we find with computed tomography, and causes a complication in the form of which we initially plan to extrude, but we can adapt to this tomography.”

The month passed, in principle, the team needed to capture any gas present inside the exterior protection tube and, finally, perforate the interior container, to extract the lunar gases that can be used in the interior.

“We have extracted gas from this nucleus and we are waiting for help from the scientists when they intend to find the company of lunar gas to observe different differences (samples of chemistry for chemical analysis)”, says Zeigler.

The analysis and computed tomography assures that no major surprises are produced to open the shelf; y, juntos, ayudaron to find a plan for dissection. Prior to the 21st and 22nd March events, the conservative assistant of the Apollo masters, Juliane Gross, also realized the results of the extrusion process with a nucleus simulated in the Johnson laboratory.

Gross compares the process of extrusion with the elaboration of furniture, except for the restriction of mobility with the brazos debido a los enormes guantes que utilizan. The extrusion of the specimen with specialty tools requires a meticulous level of organization.

“Let’s do this step, we will not lose the pieces and small tornels,” said Gross.

In the end, it was very difficult to train hard: the dollar was irradiated by the brazos and men. Pero Gross said that he was duda valió la pena.

“We are the first people to be in this arena for the first time,” said Gross. “Is it simply the best of the world, like a girl in a shop, really?”

The Apollo program is a part of NASA’s opportunity to try methods of creation that created the Moon, based on the fact that it works in the Land, and to evolve these methods with each mission.

“The terrestrial samples and the lunar samples are very different, so the team of Artemis has been able to learn about the design of hermitages,” said Zeigler. “No commensaron con el Apolo 11. No commenzaron desde cero. Commenzaron con el Apolo 17, funcionó muy bien y están avanzando desde ese punto hacia Artemis ”.

Debido a que los astronautas de Artemis irán maş alá del ecuador lunar (más conocido), hasta el Polo Sur, con sus condiciones a veces criogénicas o congeladas, y su illuminatiçón espectacular, el suelo lunar allí ofrece perspectivas su magnífic.

“El Polo Sur de la Luna is a great place for the possible accumulation of large deposits of volatile fluids (substances that evaporate at normal temperatures, such as water and carbon dioxide)”, said Lori Glaze, director of the Planetary Science Division in the NASA seat. “These voices can give you a track about the origin of the water in this part of the solar system, the sea of ​​comets, asteroids, solar wind and others.”

And we have the masters of Apollo in proportion to NASA information about the natural satellites of Tierra, a new master of exotic places in exotic places in the lunar superficies, and debates of the superficies, assists the agency and will be able to buy more information. on geological evolution.

“We have the opportunity to endorse some other people who are really important about the Moon, proving that it has been registered and preserved in the regulation of the Apollo models,” said NASA conservator Astromaterials, Francis McCubbin. plazo, para que los cientificos 50 años después pudieran analizarlos. In Artemis, we hope to offer the opportunity to a new generation of scientists ”.
