Artist's concept of a derelict satellite being reeled in after being harpooned by the e.De...

In 2021, as part of its Clean Space Initiative, ESA plans to launch the e.DeOrbit mission. The aim of this mission is to clean up the important polar orbits between altitudes of 800 to 1,000 km (500 to 625 mil) that face the prospect of becoming unusable due to the increasing buildup of space debris. The ESA has now announced plans to examine the potential for the mission to use space harpoons to capture large items, such as derelict satellites and the upper stages of rockets.  Read More

Falcon 9 on the launch pad

SpaceX today aborted the launch of a Falcon 9 rocket carrying six Orbcomm OG2 communication satellites; the second mission flight of a Falcon booster equipped with landing legs. Six minutes and nine seconds before the lift off, mission control declared the abort due to a problem with the second stage of the rocket.  Read More

Inmarsat is to launch a satellite to provide in-flight broadband services across the EU, s...

Satellite communications firm Inmarsat has announced that it is to deliver a new high-speed broadband service for airline passengers in the EU. Connectivity will be delivered by both a ground-based network and a new satellite. The service could launch as early as 2016.  Read More

Control of NASA's Global Precipitation Measurement Core satellite (GPM) has been handed over to the team of engineers who will maintain operational control of the piece of equipment for the remainder of its life in space. The GPM mission, launched on February 27 atop a Japanese manufactured H-IIA rocket, will work in tandem with a constellation of pre-existing satellites with the objective of creating a unified measurement of rain and snow-fall on a global scale.  Read More

Earth is surrounded by a cloud of debris that is becoming increasingly hazardous to operat...

As part of its Clean Space Initiative, the ESA is planning a satellite salvage mission called e.DeOrbit that would use a satellite to net space debris and remove it from low Earth orbit. To capture such debris using an autonomous system, it needs to be targeted effectively, which is difficult when the debris is tumbling unpredictably. To fine tune the design of the e.DeOrbit mission, the ESA will commission a study to shed light on why space debris tumbles the way it does.  Read More

An analysis of data from the European Space Agency's (ESA) CryoSat satellite shows that ice loss in the Antarctic is increasing at an exponential rate. It is estimated that the polar region now loses 159 billion tonnes of ice each year, with the worst instances of degradation located in the Western area of the Amundsen Sea.  Read More

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
