    U.S. Air Force is concerned about American dependence on space satellites, particularly the GPS birds. The air force believes China is developing the ability to carry out a major attack on American military satellites. Their proposed solution is to take GPS out of orbit, and make it portable. High flying aircraft, UAVs or blimps would take over satellite communications, surveillance and navigation (GPS) chores, although for smaller areas. This would make GPS, and other satellite functions, more resilient to attack. This is part of a trend in which military satellites are getting priced out of the market by cheaper manned...

    Memories in New Delhi run deep about how India's relative tardiness in developing strategic offensive systems [nuclear weapons] redounded in its relegation on 'judgment day' [when the nuclear Non-Proliferation Treaty was signed in 1968] to the formal category of non-nuclear weapons state," said Sourabh Gupta, senior research associate at Samuels International Associates in Washington, DC. "With its early support of the former US president George W Bush's ballistic missile defense program and its current drive to develop anti-ballistic missile/anti-satellite capability, New Delhi is determined not to make the same mistake twice," added Gupta. "If and when globally negotiated restraints are...

    The first IP router on a commercial satellite has successfully passed its in-orbit test, moving the military and commercial customers closer to an era of faster satellite communications. The Internet Routing in Space (IRIS) technology is expected to reduce latency and increase efficiency, said Steven Boutelle, vice president of Cisco Global Government Solutions Group. Boutelle, who served as the U.S. Army’s chief information officer prior to joining Cisco, said IRIS can route data to multiple ground receivers in a single step, eliminating the need to double-hop to a teleport, reducing latency and increasing transponder utilization. The router and modem software...

    Iran will unveil three new satellites in February, a report said Wednesday, amid Western concerns that Tehran is using its nuclear and space industries to develop atomic and ballistic weapons. ISNA news agency quoted Communications Minister Reza Taghipour as saying that one of the three home-built communications satellites is still under construction. Taghipour named the three satellites as Toloo (Dawn), Ya Mahdi and Mesbah-2, but did not elaborate on exactly when they would be launched. Ya Mahdi, Taghipour said as quoted by ISNA, was an "experimental satellite" and the launch would be for testing camera and telecommunications equipment. Mesbah-2, which...

    RIA Novosti/Space War ^ | 1/18/2010 | by Ilya Kramnik
    The U.S. media suspects China and India of developing anti-satellite weapons. An article to this effect has been published the New Scientist magazine. Until recently, only the Soviet Union, its legal successor Russia and the United States were capable of developing anti-satellite weapons. U.S. analysts now think that China and India are acquiring similar capabilities. To what extent are such fears justified? It is hard to overestimate the role played by military satellite systems. Since the 1970s, an increasingly greater number of troop-control, telecommunications, target-acquisition, navigation and other processes depend on spacecraft which are therefore becoming more important. At this...
  • US Space-Based Missile Warning System Achieves Key Milestone

    The U.S. Air Force/Lockheed Martin team developing the Space-Based Infrared System (SBIRS) program has achieved two key milestones: a testing milestone demonstrating that the ground system is on track to support launch of the first SBIRS geosynchronous (GEO-1) satellite in the constellation, and a maturity milestone moving the ground system into the next level of integration. SBIRS will deliver unprecedented, global, persistent infrared surveillance capabilities by providing early warning of missile launches, and simultaneously supporting other missions including missile defense, technical intelligence and battlespace awareness. The testing milestone, known as the Combined Day-In-The-Life Test (CDITL), validated the functionality, performance, and...

    Italian companies—with Rome's backing—have equipped Iran's military and contributed to the regime's satellite and possibly nuclear programs. When it comes to appeasing the Islamic Republic, no other Western nation has stooped lower than Italy. Amid the international outrage over the Iranian regime's brutalization of its own people, Italian Foreign Minister Franco Frattini warned Europe "must not burn every bridge because Iran is a key figure" in the region. While rejecting any military action to stop Tehran's nuclear weapons program, Mr. Frattini urged the West to "avoid those [sanctions] that are connected with Iranian national pride." What may sound like a...

    Engineers at NASA’s Goddard Space Flight Center are developing an in-orbit test bed to validate techniques for refueling satellites that weren’t designed to be refueled, using procedures growing out of the experience gained servicing the Hubble Space Telescope. Preston Burch, the Hubble program manager, said Jan. 11 that the experiment would use the Canadian-built Special Purpose Dexterous Manipulator, known as Dextre, to simulate cutting into a spacecraft’s insulation, tapping into its fuel plumbing, and refilling its tanks to extend its service life. “We’ve already developed a prototype tool that’s pretty cool that can cut through the external skin or insulation...

    Facing a looming gap in its mobile satellite communications coverage, the U.S. Navy plans to tap a new service developed by commercial provider Iridium Communications LLC as it waits for its next-generation constellation to come on line. The Defense Information Systems Agency (DISA), which buys commercial satellite capacity on behalf of Pentagon users, plans to spend about $20 million this year on the Netted Iridium service, Bruce Bennett, DISA’s director of satellite communications, teleports and services, said in a Dec. 14 interview. DISA spent about $70 million on Iridium mobile satellite services in 2009, and the total amount should increase...

    The U.S. Air Force will contract to have its Space Based Space Surveillance (SBSS) system satellite placed into storage due to continued technical difficulties with the Minotaur 4 rocket that have delayed the spacecraft’s launch indefinitely, according to government documents. The Minotaur 4 rocket, built by Orbital Sciences Corp. of Dulles, Va., and based in part on excess missile motors, was originally planned to debut in October 2009 with the SBSS launch. But the Air Force issued a statement that month saying the rocket had problems and would remain grounded indefinitely, though no further explanation was given. In a solicitation...

    February 24, 2009, NASA's 280 million dollar Orbiting Carbon Observatory fell into the Antarctic after it failed to make orbit. Now, I'm not a Truther who believes 9/11 was an inside job produced by George Bush, nor am I certain BO is a U.S. citizen, but where there's smoke, there's fire from a burning birth certificate somewhere . . . NASA's carbon checking satellite was launched with the intention of definitively mapping the amount and effects of that evil atom, carbon, on the earth, which has alone been responsible for loading western universities with a non diversity of well funded...

    The U.S. Air Force is asking industry to explore options for quick delivery of a space-based missile warning system, a move which is likely connected to reports that the service's newest ballistic missile warning satellite is failing in orbit. A broad sources sought notice was issued Nov. 24, and a more specific and classified request for information is expected Dec. 1. This flurry of activity is likely a response to concerns of a space-based missile warning gap, according to industry officials. The 23rd Defense Support Program (DSP) satellite, launched into orbit last November, has drifted from its original position in...

    Iran is preparing to launch its second indigenous communications satellite aboard a Safir-2 (Ambassador) booster rocket, an event that will test the country's ballistic missile capabilities. And, if it's successful, it could impact significantly on U.S.-led negotiations with Tehran over its nuclear ambitions by demonstrating the Iranians' growing mastery of missile technology. Satellite launch vehicles such as the two-stage Safir-2, believed to be a modified Shehab-3 intermediate-range ballistic missile, are generally considered to have a potential application as an intercontinental ballistic missile. Ten months ago Iran successfully launched the Omid 1 (Hope) satellite into orbit atop a 72-foot Safir from...
