India a major player in Earth observation satellites - Out of Space

Duncan Steel Oct 15, 2019

While many imagine that countries like the USA and Europe dominate space activities, in fact India is now a major player on this stage. It launches satellites for its own purposes and also commercially, and has constellations orbiting our planet and returning data of vital importance to that nation in many ways.  Yesterday I was really pleased to give a … Read More

Tracking satellites launched from NZ - Out of Space

Duncan Steel Jun 27, 2019

With so many thousand satellites now in orbit, and tens of thousands of other tracked items, one might think that it is difficult keeping tabs on them, simply as an interested person. In fact it is quite straightforward, with long lists of orbital elements freely available for all except the few satellites deemed by the US Government to require secrecy, … Read More

The annual beanfeast for the US satellite industry — featuring major participation from European nations and companies in particular — is the SATELLITE congress held at the Washington Convention Center, a few blocks from the White House.

As I write, the Dragon capsule – a spacecraft intended to loft US astronauts into orbit – has been docked with the Space Station for almost 18 hours on its initial test flight. It happens that you will be able to see the station plus capsule passing over New Zealand each evening for the next week or so, before the … Read More

Space War and NZ’s Position - Out of Space

Duncan Steel Jan 09, 2019

With regard to tracking military satellites newly-launched from eastern Asia and potentially of concern to our allies, New Zealand’s geographical position is of huge (yet overlooked) significance.   Surely no-one could imagine that space-wise there is not a lot going on at present, with another probe just landed on Mars, three other spacecraft missions having encounters with asteroids, and … Read More

Ken Perrott Apr 09, 2010

Here’s an animation showing the accumulation of debris in near earth orbit due to human activity since 1957. It does look very cluttered but remember the articles aren’t to scale. YouTube – Space debris over time. And where is all the junk coming from (click on image to get more detail – thanks to Michæl Paukner’s [...] … Read More
