ESA sets its sights on harpooning space debris

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

NASA's GPM satellite tested and ready to go

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.

ESA endeavours to understand the unpredictable tumbling of space debris

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

Yaliny wants to turn any smartphone into a satellite phone

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.

B612 Foundation highlights the risk of city-destroying asteroids

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.
