Neil Armstrong, first man to walk on the Moon, passes away
Aug 25, 2012 -  Neil Armstrong, the former NASA astronaut who became the first person to walk on the surface of the Moon in 1969, passed away Saturday at the age of 82. Armstrong died following complications resulting from cardiovascular procedures, according to a statement released by his family. Armstrong underwent cardiac bypass surgery earlier this month. Armstrong is best known as commander of Apollo 11, the first crewed mission to land on the Moon, and he became the first person to set foot on the Moon, joined by lunar module pilot Buzz Aldrin. Armstrong also flew on the Gemini 8 mission in 1966. Armstrong left NASA in 1971 and went on to careers in academia and industry, and also served on the NASA Advisory Council.

Weather delays Atlas launch to next week
Aug 25, 2012 -  Poor weather prevented Saturday's planned launch of a pair of NASA space science satellites, and the threat of a tropical storm will keep the rocket grounded until late next week. NASA had hoped to launch the twin Radiation Belt Storm Probes (RBSP) at 4:07 am EDT (0807 GMT) Saturday, one day after a technical problem scrubbed the first launch attempt. However, stormy weather prevented the launch from taking place during a 20-minute window. NASA announced later Saturday morning that the launch would be postponed to no earlier than Thursday, August 30, because of concerns about Tropical Storm Issac, which is approaching southern Florida and likely to preclude launch attempts for several days. The Atlas 5 rocket will be rolled back to its assembly building until the storm passes. The two RBSP spacecraft will study the Van Allen radiation belts that surround the Earth.

XCOR Aerospace’s multi-talented Lynx spaceplane set for KSC

August 27th, 2012 - XCOR Aerospace – who are believed to be close to arranging a deal to set up a base at the Kennedy Space Center (KSC) – have outlined the three versions of their Lynx suborbital spaceplane. The reusable vehicle will even include the ability to send small spacecraft to Low Earth Orbit (LEO), utilizing an upper stage, housed in an installed dorsal pod.  XCOR Aerospace is a small, privately held California corporation that has a focus on the research, development, project management and production of Reusable Launch Vehicles (RLVs), rocket engines and rocket propulsion systems. KSC requires no introduction, following its world famous career launching American astronauts into space. However, that is – for now – at an end, leaving the Center with an arduous task of trying to attract commercial companies to the Space Coast, as part of its “multi-user” spaceport brief.  FULL STORY

Curiosity lands safely on the surface of Mars
Aug 6 - Mars Science Laboratory illustration (NASA/JPL) NASA's Mars Science Laboratory mission successfully landed the Curiosity rover on the surface of Mars late Sunday night. The rover touched down on the surface of Gale Crater at 10:14 pm PDT Sunday (1:14 am EDT, 0514 GMT Monday), with signals confirming the landing arriving at Earth approximately 15 minutes later. Initial black-and-white images returned from the rover's "Hazcam" hazard avoidance camera showed the rover to be on relatively flat terrain, with what may be the crater wall in the distance. The rover's entry, descent, and landing all appeared to go as planned, despite warnings prior to the landing of the risks involved with landing on Mars, particularly using the previously-untried "skycrane" system. The mission teams plans to slowly check out the rover's systems and instruments in the coming days and weeks, preparing for a mission to explore Gale Crater slated to last at least two years.
NASA lands car-size rover beside Martian mountain Aug. 6, 2012- NASA's most advanced Mars rover Curiosity has landed on the Red Planet. The one-ton rover, hanging by ropes from a rocket backpack, touched down onto Mars on 6 August (UTC) to end a 36-week flight and begin a two-year investigation.
The Mars Science Laboratory (MSL) spacecraft that carried Curiosity succeeded in every step of the most complex landing ever attempted on Mars, including the final severing of the bridle cords and flyaway manoeuvre of the rocket backpack.
Curiosity landed near the foot of a mountain 5 km tall and 159 km in diameter inside Gale Crater. During a nearly two-year prime mission, the rover will investigate whether the region ever offered conditions favourable for microbial life.
Curiosity returned its first view of Mars, a wide-angle scene of rocky ground near the front of the rover. More images are anticipated in the next several days as the mission blends observations of the landing site with activities to configure the rover for work and check the performance of its instruments and mechanisms.
Confirmation of Curiosity's successful landing came in communications relayed by NASA's Mars Odyssey orbiter and received by the Canberra, Australia, antenna station of NASA's Deep Space Network.
Curiosity carries 10 science instruments with a total mass 15 times as large as the science payloads on the Mars rovers Spirit and Opportunity. Some of the tools are the first of their kind on Mars, such as a laser-firing instrument for checking elemental composition of rocks from a distance. The rover will use a drill and scoop at the end of its robotic arm to gather soil and powdered samples of rock interiors, then sieve and parcel out these samples into analytical laboratory instruments inside the rover.
To handle this science toolkit, Curiosity is twice as long and five times as heavy as Spirit or Opportunity. The Gale Crater landing site places the rover within driving distance of layers of the crater's interior mountain. Observations from orbit have identified clay and sulfate minerals in the lower layers, indicating a wet history.
The mission is managed by JPL for NASA's Science Mission Directorate in Washington. The rover was designed, developed and assembled at JPL.

Arianespace celebrates 50th launch success in a row
Rocket: Ariane 5 ECA; Payload: Intelsat 20, HYLAS 2; Date: 2 August 2012, 2054 UTC; Launch site: Kourou, French Guyana. The successful mission marked the milestone 50th consecutive success for its Ariane 5 heavy-lift launcher.
Intelsat 20 was installed as the upper payload on this latest Ariane 5 launch, and was released first during the mission at 28 minutes into the flight. Built for international satellite operator Intelsat by Space Systems/Loral of Palo Alto, California based on its 1300-series platform, Intelsat 20 had a mass of approximately 6,090 kg at lift-off, and is configured with Ku-band, C-band and Ka-band transponders. Intended to replace the Intelsat 7 and Intelsat 10 satellites in orbit, Intelsat 20 is to provide video, telephone and data transmission services for Europe, Africa, Russia, Asia and the Middle East. The HYLAS 2 satellite orbited by Ariane 5 on this flight was deployed 34 minutes after lift-off, and will be used by European satellite operator Avanti Communications. Produced by Orbital Sciences Corporation of Dulles, Virginia using the Star 2.4E platform, HYLAS 2 is equipped with Ka-band transponders for data capacity offered to telecommunications, enterprise and government customers in Europe, the Middle East and portions of Africa.
Ariane 5's combined lift performance in the 50 straight successes totals more than 434,000 kg, delivering payloads to geostationary transfer orbit, low Earth orbit, Sun-synchronous polar orbit and Earth escape trajectories. Arianespace CEO Jean Yves Le Gall said today's mission also was historic from another aspect, as its lift performance of nearly 10.2 metric tons beat the world's record for total mass launched to geostationary transfer orbit. "We captured the previous record last year with just over 10 tons, and this demonstrates the pertinence of our improvement strategy, which - step-by-step - enables us to increase the capacity of our launcher while retaining its extraordinary reliability."
The Arianespace mission pace will continue with its next two flights announced for September: a mid-month launch of another Ariane 5 from the Spaceport with the Astra 2F and GSAT-10 telecommunications relay platforms; and the 19 September mission of a Soyuz from Baikonur Cosmodrome in Kazakhstan, performed by Arianespace's Starsem affiliate and carrying Eumetsat's MetOp-B meteorological satellite.
