  • Exploration of the Moon
    Exploration of the Moon The physical exploration of the Moon began when Luna 2, a space probe launched by the Soviet Union, made an impact on the surface of the Moon on September 14, 1959. Prior to that the only available means of exploration had been observation from Earth. The invention of the optical telescope brought about the first leap in the quality of lunar observations. Galileo Galilei is generally credited as the first person to use a telescope for astronomical purposes; having made his own telescope in 1609, the mountains and craters on the lunar surface were among his first observations using it. NASA's Apollo program was the first, and to date only, mission to successfully land humans on the Moon, which it did six times. The first landing took place in 1969, when astronauts placed scientific instruments and returnedlunar samples to Earth.

Contents Early history Space race Recent exploration Plans Past and future lunar missions See also References External links Early history The ancient Greek philosopher Anaxagoras (d. 428 BC) reasoned that the Sun and Moon were both giant spherical rocks, and that the latter reflected the light of the former. His non-religious view of the heavens was one cause for his imprisonment and eventual exile.[1] In his little book On the Face in the Moon's Orb, Plutarch suggested that the Moon had deep recesses in which the light of the Sun did not reach and that the spots are nothing but the shadows of rivers or deep chasms.

    SpaceX CRS-4 National Aeronautics and Fourth Commercial Resupply Services Flight Space Administration to the International Space Station September 2014 OVERVIEW The Dragon spacecraft will be filled with more than 5,000 pounds of supplies and payloads, including critical materials to support 255 science and research investigations that will occur during Expeditions 41 and 42. Dragon will carry three powered cargo payloads in its pressurized section and two in its unpressurized trunk. Science payloads will enable model organism research using rodents, fruit flies and plants. A special science payload is the ISS-Rapid Scatterometer to monitor ocean surface wind speed and direction. Several new technology demonstrations aboard will enable bone density studies, test how a small satellite moves and positions itself in space using new thruster technology, and use the first 3-D printer in space for additive manufacturing. The mission also delivers IMAX cameras for filming during four increments and replacement batteries for the spacesuits. After four weeks at the space station, the spacecraft will return with about 3,800 pounds of cargo, including crew supplies, hardware and computer resources, science experiments, space station hardware, and four powered payloads.

It consists of a humorous 24-minute show and educator’s package. The Orion Educator’s Guide is designed for Planetarians, Teachers, and parents. The information is researched, organized, and laid out so that the educator need not spend hours coming up with lesson plans or labs. This has already been accomplished by certified educators. The guide is written to alleviate the fear of space and the night sky (that many elementary and middle school teachers have) when it comes to that section of the science lesson plan. It is an excellent tool that allows the parents to be a part of the learning experience. The guide is devised in such a way that there are plenty of visuals to assist the educator and student in finding the Winter constellations.

  • Sentinel-1A Launch
    SENTINEL-1A LAUNCH Arianespace’s seventh Soyuz launch from the Guiana Space Center will orbit Sentinel-1A, the first satellite in Europe’s Earth observation program, Copernicus. The European Space Agency (ESA) chose Thales Alenia Space to design, develop and build the satellite, as well as perform related tests. Copernicus is the new name for the European program previously known as GMES (Global Monitoring for Environment and Security), and is the European Commission’s second major space program, following Galileo. Copernicus is designed to give Europe continuous, independent and reliable access to Earth observation data. With the Soyuz, Ariane 5 and Vega launchers at the Guiana Space Center (CSG), Arianespace is the only launch services provider in the world capable of launching all types of payloads into all orbits, from the smallest to the largest geostationary satellites, from satellite clusters for constellations to cargo missions for the International Space Station (ISS). Arianespace sets the launch services standard for all operators, whether commercial or governmental, and guarantees access to space for scientific missions. Sentinel-1A is the 50th satellite with an Earth observation payload to be launched by Arianespace. Arianespace has seven more Earth observation missions in its order book, including four commercial missions (signed in 2013 and 2014). The Copernicus program is designed to give Europe complete independence in the acquisition and management of environmental data concerning our planet. ESA’s Sentinel programs comprise five satellite families: Sentinel-1, to provide continuity for radar data from ERS and Envisat. Sentinel-2 and Sentinel-3, dedicated to the observation of the Earth and its oceans.

Based on orbital data in ESA’s DISCOS database and on orbital data provided by KIAM the situation near the geostationary ring is analysed. From 1523 objects for which orbital data are available (of which 0 are outdated, i.e. the last available state dates back to 180 or more days before the reference date), 519 are actively controlled, 795 are drifting above, below or through GEO, 189 are in a libration orbit and 19 are in a highly inclined orbit. For 1 object the status could not be determined. Furthermore, there are 59 uncontrolled objects without orbital data (of which 54 have not been cata- logued). Thus the total number of known objects in the geostationary region is 1582.
