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

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 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
