A National Research Council panel is calling on policymakers to establish a sustained and enhanced land imaging program to ensure data continuity from the 40-year Landsat effort. Stable follow-on efforts would end a chaotic history of federal oversight of Landsat, while assuring spacecraft continuity, technically advanced sensors and data management, and the widest possible distribution of the imagery, according to the panel’s Aug. 8 report.
Recent observations with the Hubble Space Telescope point to highly energetic mergers of binary neutron stars or neutron/black hole pairs as the source of mysterious, short-duration gamma-ray bursts. The findings, published online Aug. 3 in the journal Nature, address a mystery dating to the detection of powerful but unsourced gamma-ray flashes by U.S. Vela satellites placed in Earth orbit during the 1960s to document violations of the 1963 Nuclear Test Ban Treaty (signed by the U.S., the former USSR and the U.K.).
MAVEN PREPARED: NASA’s next Mars spacecraft is at Kennedy Space Center, Fla., being prepared for its November launch aboard at Atlas V -401 rocket. The Mars Atmosphere and Volatile Evolution (Maven) spacecraft was flown to Kennedy on Aug. 2 from Buckley AFB, Colo., near Lockheed Martin’s facility in Littleton, where it was built.
Boeing’s 702 Small Platform electric satellite series has cleared its critical design review, permitting the first spacecraft to move into the assembly phase and remain on schedule for launch in the first quarter of 2015.
Deputy NASA Administrator Lori Garver, who has been a policy lightning rod at agency headquarters as the Obama administration worked to shift U.S. human spaceflight from a government-run operation to a commercial venture, has resigned to take a job as general manager of the Air Line Pilots Association (ALPA). Associate Administrator Robert Lightfoot, the agency’s No. 3 manager and top-ranking civil servant, is a likely possibility to fill Garver’s post on an acting basis until the White House can nominate another political appointee.

Astronauts aboard the International Space Station (ISS) expect to greet the Japan Aerospace Exploration Agency’s HTV-4 early Aug. 9, following the unmanned cargo resupply spacecraft’s successful weekend liftoff from the Tanageshima Launch Center.
WGS WINDOW: The U.S. Air Force is anticipating a launch window for its sixth Boeing Wideband Global Satcom (WGS) spacecraft of 49 min. starting at 8:29 a.m. EDT Aug. 7. The satellite, which will provide high-bandwidth data and voice communications for U.S. and Australian forces, will be lofted by a United Launch Alliance Delta IV with four solid-rocket motors and a 5-meter fairing, from Cape Canaveral.WGS-6 is the final “Block 2” standard satellite, which includes a bypass to allow for quick transfer of video data collected by unmanned aircraft.
A more robust and maturing sensor network for the U.S. missile defense architecture is allowing planners to expand the options for an enhanced kill vehicle (KV).
The European Union is keen to set up its own network of space surveillance assets that could track spy satellites and near-Earth objects, help satellite operators avoid orbital-debris collisions and protect critical infrastructure when spent spacecraft or other objects enter Earth's atmosphere.

A Lunar X-Prize contender plans to mount a commercial mission to the Moon as a step toward a private lunar sample-return flight around 2020 and ultimately, perhaps, lunar mining for water and valuable minerals. Moon Express Inc.—a strong contender in the $30 million Google Lunar X-Prize competition—says it will mount a follow-on mission to the Moon's south pole in partnership with the International Lunar Observatory Association (ILOA), one of the piggyback customers for its X-Prize entry.
As the European Union's biggest defense powers pare back military budgets, the crisis in public spending is bolstering the EU's case for taking on more responsibility in the realm of defense, space and security. The European Commission (EC) issued a long-awaited slate of broad policy proposals last month that would harmonize defense commerce in Europe, develop common standards, fund dual-use R&D and ultimately see the EU's executive arm purchase and operate its own military hardware.

Arabsat has signed a contract to build its new headquarters in the diplomatic quarter in Riyadh. The new building will be constructed on land provided by the Government of the Kingdom of Saudi Arabia and covers an area of nearly 14,000 square meters.
The Global Space and Satellite Forum in Abu Dhabi has heard how US-based ViviSat plans to extend the life of geosynchronous satellites that are running out of fuel with its Mission Extension Vehicle (MEV).
FALCON FLIGHT: Space Exploration Technologies (SpaceX) is set to launch three Canadian-built C-band Earth-observation radar satellites for MacDonald, Dettwiler and Associates under a “launch reservation contract” awarded to the Hawthorne, Calif.-based launch service provider July 30. Funded by the Canadian Space Agency, the Radarsat Constellation Mission is designed to continue the C-band dataset of earlier Radarsats with as many as four daily passes over Canadian territory and “several” passes a day over the Northwest Passage.
FRANKFURT — EADS has decided to make significant changes to its corporate structure and put the entire company under the Airbus brand. The board of directors followed a proposal put forward by CEO Tom Enders to change the company’s name to Airbus Group. Defense and space units Cassidian and Astrium will be merged and called Airbus Defense and Space. Eurocopter also will lose its current brand and be re-launched as Airbus Helicopters.
