An Atlas V 551 launches the Pluto New Horizons probe toward the fringes of the Solar Syste...

Lockheed-Martin (LM) has a problem. Their Atlas V orbital launch system, while very popular with the US military, at around US$225M per launch is too expensive to compete effectively for commercial missions, whose launch costs are generally about half that amount. As part of an effort to reposition their services, LM is now offering a 100 percent money-back or reflight guarantee if the launch vehicle causes mission failure. The guarantee covers the cost of the vehicle launch, but not the cost of the satellite.  Read More

The SPHERES robots were put through a simulated follow-the-leader exercise (Image: NASA)

Controlling a robot in space from the ground can be a bit like hitting a moving target. There’s a one to three second delay as data passes back and forth between the robot and ground control, which means that operators have to anticipate how the robots will move during these delays. This week, the Lockheed Martin Advanced Technology Center (ATC) announced the first-ever demonstration of collaborative tele-operations that involved control of robots on the International Space Station (ISS) by astronauts on the ISS and operators on the ground.  Read More

The Dish Super Joey allows users to record up to eight TV shows at once

TV shows that clash, or family members that clash over TV shows, mean that we don't always get to watch the show we want. A new service from US-based satellite provider Dish, however, can change that. The Super Joey allows users to record up to eight simultaneous TV programs.  Read More

ESA's 15 m-diameter dish antenna at the European Space Astronomy Centre (ESAC), near Madri...

As you might expect, acquiring a signal from a satellite traveling at speeds of over 17,400 mph can be a tricky business. A new system called SARAS, which is a Spanish acronym for "Fast Acquisition of Satellites and Launchers," more than doubles the effective area of the receiving dish antenna, allowing the signal to be acquired much faster.  Read More

Planet X is a hypothetical star or planet, theorized to be responsible for Earth's mass ex...

A study of data captured by NASA's Wide-Field Infrared Survey Explorer (WISE) satellite has disproved the existence of the hypothesized large celestial body, dubbed "Planet X." The planet or companion star was, some believed, responsible for the periodic mass extinctions that have taken place in Earth's past.  Read More

The GPM Core Observatory is launched aboard a Japanese H-IIA rocket from the Tanegashima S...

The Global Precipitation Measurement (GPM) Core Observatory was launched last Thursday aboard a Japanese H-IIA rocket that blasted off from Tanegashima Space Center on Tanegashima Island in southern Japan. Weighing in at 4-ton, the GPM is the largest spacecraft ever built at NASA's Goddard Space Flight Center and will help provide a more detailed picture of the Earth's precipitation to assist climate scientists and help improve forecasting of extreme weather events.  Read More

Netting a satellite (Image: ESA)

With the film Gravity hoovering up awards for its portrayal of astronauts dodging colliding satellites, now seems a good time to talk about the very real threat posed by space debris. It’s small wonder, then, that ESA’s Clean Space initiative is looking at developing a satellite that can rendezvous with space debris and render it harmless by netting it like fish. The proposal is just one of the ideas to be discussed as part of a symposium this May focusing on the space agency's e.DeOrbit mission.  Read More

The Iridium Go is a satellite-based hotspot for your smartphone or tablet

Smartphones are practically everywhere. But if you're in the middle of nowhere without a signal, that iPhone 5s or Galaxy S4 won't do you much good. Many people already turn to satellite phones when they're at sea or in other far-off places, but a new device from Iridium takes a satellite signal and turns it into a Wi-Fi hotspot for your existing mobile devices.  Read More

NASA is set to launch a new satellite designed to take detailed, near real-time measurements of rain and snowfall on a global scale whilst mapping the interior of storm systems. The Core Observatory of the Global Precipitation Measurement (GPM) has been in development since 2005 and is a collaboration project between NASA and the Japanese Space Agency (JAXA). The satellite is due to be launched on the Japanese manufactured H-IIA delivery vehicle from the Tanegashima Space Centre, Tanegashima Island, Japan, on February 27.  Read More

SpaceX has launched a second satellite into a geostationary transfer orbit

Commercial space company Space Exploration Technologies (SpaceX) has launched a second satellite into a geostationary transfer orbit. Its Falcon 9 rocket lifted off from Space Launch Complex 40 at Cape Canaveral in Florida and successfully delivered a TV and telecoms satellite for Thai-based communications provider Thaicom into position.  Read More
