KSC-04-S-00284 (ksc 073004 lunar rocks).webm

NASA's Lunar Sample Laboratory Facility is home to the most cherished -- and scientifically important -- relics of the Apollo program. Now, the laboratory facility at Johnson Space Center in Houston is celebrating its 25th anniversary. After two years of construction, officials dedicated the facility on July 20, 1979 -- the ten-year anniversary of the Apollo 11 Moon landing. Twelve NASA astronauts visited the Moon's dusty surface during six Apollo missions. They returned with a total of 842 pounds of lunar material, including rocks, core samples, pebbles, even sand and dust.NASA needed a permanent storage facility to protect the samples from floods, hurricanes, tornadoes and contaminants. These extra precautions would keep these priceless samples in pristine condition. From these special needs, the Lunar Sample Laboratory Facility was born. Today, 35 years after the first lunar landing, the samples continue to attract scientists' attention.

Wikidata Lab XXXII- Consultando o Wikidata.webm

💻 Participe do primeiro Wikidata Lab de 2022 sobre queries próxima quinta-feira (17/02) às 14h! Este Wikidata Lab será um evento online que pretende compartilhar recursos e capacidades para a integração do Wikidata com outros projetos Wikimedia, em particular a Wikipédia. O evento contará com uma apresentação e uma série de atividades práticas e discussões sobre o processo de consulta ao banco de dados do Wikidata, utilizando-se SPARQL e Listeria. O treinamento será coordenado pelos wikimedistas Ederporto e ErikaGuetti. Erika Guetti Suca é doutoranda em ciências da computação pela Universidade de São Paulo (USP) e atua essencialmente nas áreas de representação do conhecimento, privacidade de dados e web semântica. 📭 Envie uma mensagem para eventos@wmnobrasil.org para receber o link do Google Meet para poder participar da parte prática do evento ▶ Página do evento: https://w.wiki/4nMA

CSIRO ScienceImage 3742 Pye Laboratory Wind Tunnel.jpg

The special low-speed wind tunnel at CMAR's Pye laboratory allows scientists to undertake fundamental studies on how air interacts with the earth's surface. At this 'boundary layer', both smooth and turbulent flows are possible. The wind tunnel is driven by a powerful double-inlet centrifugal fan. Air is blown down the test section, enters the ambient space, and is then recycled. In detail, air flows from the fan through a coarse-flow straightener, a wide-angle diffuser with screens, a fine straightener, a settling chamber with screens, then a contraction, the working section, and finally the outlet diffuser. The working section is 1.8 m wide, 0.9 m high, and 16 m long. Several methods of air-speed control are available, providing high speeds for turbulent boundary-layer studies and very low speeds for experiments on flow over plants. The contraction ratio is 5.5:1, similar to that of a general purpose tunnel.

Curiosity - The Next Mars Rover.jpg

This artist concept features NASA's Mars Science Laboratory Curiosity rover, a mobile robot for investigating Mars' past or present ability to sustain microbial life. Curiosity is being tested in preparation for launch in the fall of 2011. In this picture, the rover examines a rock on Mars with a set of tools at the end of the rover's arm, which extends about 2 meters (7 feet). Two instruments on the arm can study rocks up close. Also, a drill can collect sample material from inside of rocks and a scoop can pick up samples of soil. The arm can sieve the samples and deliver fine powder to instruments inside the rover for thorough analysis. The mast, or rover's "head," rises to about 2.1 meters (6.9 feet) above ground level, about as tall as a basketball player. This mast supports two remote-sensing instruments: the Mast Camera, or "eyes," for stereo color viewing of surrounding terrain and material collected by the arm; and, the ChemCam instrument, which is a laser that vaporizes material from rocks up to about 9 meters (30 feet) away and determines what elements the rocks are made of.

MSL HeatShield.jpg

The finished heat shield for NASA's Mars Science Laboratory, with a diameter of 4.5 meters (14 feet, 9 inches), is the largest ever built for descending through the atmosphere of any planet. This image shows the heat shield and a spacecraft worker at Lockheed Martin Space Systems, Denver, which built and tested the heat shield. The heat shield and the spacecraft's backshell together form an encapsulating aeroshell that will protect the mission's rover, Curiosity, from the intense heat and friction that will be generated as the flight system descends through the Martian atmosphere. The aeroshell has a steering capability produced by ejecting ballast that offsets the center of mass prior to entry into the atmosphere. This offset creates lift as it interacts with the thin Martian atmosphere and allows roll control and autonomous steering through the use of thrusters.

The major components of NASA's Mars Science Laboratory spacecraft—cruise stage atop the aeroshell, which has the descent stage and rover inside—were connected together in October 2008 for several weeks of system testing, including simulation of launch vibrations and deep-space environmental conditions. These components will be taken apart again, for further work on each of them, after the environmental testing. The Mars Science Laboratory spacecraft is being assembled and tested for launch in 2011.

MSL DescentStage.jpg

This image from early October 2008 shows personnel working on the descent stage of NASA's Mars Science Laboratory inside the Spacecraft Assembly Facility at NASA's Jet Propulsion Laboratory, Pasadena, Calif. The descent stage will provide rocket-powered deceleration for a phase of the arrival at Mars after the phases using the heat shield and parachute. When it nears the surface, the descent stage will lower the rover on a bridle the rest of the way to the ground. The larger three of the orange spheres in the descent stage are fuel tanks. The smaller two are tanks for pressurant gas used for pushing the fuel to the rocket engines.
