Orbits of the satellites launched by Rocket Lab three days ago - Out of Space

Duncan Steel Jul 02, 2019

On Saturday June 29th Rocket Lab launched another cluster of seven satellites into low-Earth orbit from the Mahia Peninsula in New Zealand’s North Island. In this blog post I illustrate the orbital paths of the ten resultant tracked items now in orbit.  In a blog post last week (June 27th) I showed the orbits of the various satellites launched … 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

Talking satellites and space in Washington - Out of Space

Duncan Steel May 16, 2019

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. It was an amazing event to attend, compared to the sort of low-key conferences we have in New Zealand.  Now I’m back in … Read More

Defending the planet from asteroids - Out of Space

Duncan Steel May 02, 2019

Astronauts, astronomers, planetary scientists, space researchers and aerospace engineers are meeting near Washington DC to discuss how we might deal with any asteroid found to be heading for a cataclysmic collision with Earth, perhaps causing a global catastrophe. That is, if it was actually found before it caught us unawares.  As I type this I am sat in a large, … Read More

Orbit of the newly-launched R3D2 satellite - Out of Space

Duncan Steel Apr 02, 2019

Last Friday Rocket Lab successfully launched another satellite from the Mahia Peninsula. In this post I describe the satellite’s orbital path, and how it will slowly vary in time over the next week.  Rocket Lab successfully launched another satellite into orbit from the Mahia Peninsula soon after midday last Friday (March 29th), a wonderful achievement. Well done to … Read More

The NZ Aerospace Challenge - Out of Space

Duncan Steel Mar 31, 2019

An open competition soon to start will provide a wonderful opportunity for smart people of any age in New Zealand to take on the challenge of how we might assess water and soil pollution using satellite and drone data. What they might choose to do in attacking such environmental problems is limited only by their imaginations, and technical capabilities. All … Read More

Space Station and docked Dragon capsule visible throughout NZ - Out of Space

Duncan Steel Mar 04, 2019

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

The Visibility of the Space Station - Out of Space

Duncan Steel Feb 22, 2019

The International Space Station (and many other satellites) can easily be viewed passing overhead using the naked eye, so long as you know when to look, and where. But why  can we see it, and how does it return so often?  In a blog post a few days ago I presented tables of times when the International Space Station (ISS … Read More

Times to Spot the Space Station - Out of Space

Duncan Steel Feb 19, 2019

It’s easy to see the International Space Station passing overhead: you just need to know when and where to look. Oh, and a clear sky. The International Space Station (ISS) regularly passes across New Zealand, a little more than 400 km above our heads – rather less than the distance between Auckland and Wellington. Most of these transits … Read More

The Nelson bush fire: What can satellite images tell us about such events? - Out of Space

Duncan Steel Feb 12, 2019

The ongoing fires in the Nelson-Tasman region have quite rightly provoked much alarm. The response of Fire and Emergency New Zealand, the NZ Police, the NZ Defence Force, and many private individuals, has been magnificent. However, the utilisation of satellite imagery for assessing such fires and then planning and responding is deficient in NZ compared to much of the rest … Read More
