Yaliny is offering inexpensive satellite-based phone calls and data coverage anywhere in t...

Visit an area outside of your cell network, take a vacation in a different country, or play a certain augmented reality game requiring you to have a constant high speed data connection, and congratulations, you’ll have an instant reminder of the current limitations of cellular networks. The Russian company Yaliny ambitiously hopes to help consumers circumvent traditional providers with Yaliny’s own network of satellites and an intermediary device called the Yaliny Point which will work with most smartphones, all for a promised US$150 for the hardware and $10 monthly thereafter.  Read More

The California-based B612 Foundation has released a video displaying the distribution of 26 multi-kiloton asteroid impacts known to have struck the Earth since the year 2000. Many of the impacts – detected by a network of satellites operated by the Nuclear Test Ban Treaty Organization – exploded with a force greater than that of the city-leveling bomb dropped on Hiroshima, which had an explosive yield of 15 kilotons.  Read More

ESA's Sentinel-1A satellite has returned its first images of Earth from space in its second week of achieving orbit. The satellite, having been launched on Apr. 3, has only recently undergone a complicated maneuver to extend its 10 m (32 ft) solar wings and 12 m (39 ft) radar imaging array.  Read More

ESA has released compelling video footage displaying the ascent of its Sentinel 1A satellite as viewed from external cameras mounted on the Soyuz Fregat launch vehicle which carried it into orbit.  Read More

The EU has launched its Sentinel 1A satellite

The EU has launched the first satellite as part of its Copernicus Earth observation program. Copernicus will provide a means of monitoring Earth's sub-systems, the atmosphere, oceans, and continental surfaces. The Sentinel 1A satellite was launched from French Guiana at 23:02 on Thursday April 3rd.  Read More

The StratoBus will hover up out of the way of airliners, but won't need to be launched int...

Satellites may be very useful for communications, navigation and other applications, but they're awfully expensive to build and launch, and once they're in orbit ... well, there's no reusing them. That's why a consortium led by Thales Alenia Space is developing the StratoBus. It's a planned autonomous airship that can be launched like a regular blimp, but that will be able to hover at an altitude of 20 km (12 miles) – that's up in the stratosphere, hence the name.  Read More

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
