Encouraging space exploration by way of the profit motive

Posted by John Lampard on Tuesday, 2 March, 2010 to the comment subset

With some asteroids valued at over US$20 trillion, due to the quantities of precious metals that they are made up of, it is only a matter of time before the exploration of space becomes a commercial undertaking.
There are millions of asteroids of different sizes and composition flying throughout space. One category, known as S-type, [...]

Are we witnessing climate change on Pluto?

Posted by John Lampard on Monday, 8 February, 2010 to the comment subset

The appearance of outer most (dwarf) planet Pluto has changed significantly in the last two years, after remaining relatively unaltered for the previous 50.
The new images, taken in 2002 and 2003, confirm that Pluto’s surface is actively changing. For reasons that are still mysterious, Pluto’s appearance remained constant for some 50 years of [...]

How exactly does the Earth evade the Sun’s (powerful) gravity?

Posted by John Lampard on Tuesday, 12 January, 2010 to the comment subset

An explanation as to why the Earth, and the other (smaller) inner planets of the solar system, have not been consumed by the Sun.
It all made sense, except for one tiny problem: this same model also suggested that a little world like Earth shouldn’t exist at all; it (or more precisely, the Moon-size proto-planets [...]

Cross the Solar System by crossing the widest webpage online

Posted by John Lampard on Friday, 18 December, 2009 to the design and art subset

P H E N O M E N A L, an online scale model of the Solar System, which is said to be half a mile in width.
Unlike most models, which are compressed for viewing convenience, the planets here are also shown at their true-to-scale average distances from the Sun. That makes this page [...]

The knowledge and wisdom of two deep-space voyagers

Posted by John Lampard on Friday, 6 November, 2009 to the comment subset

A summary of the how the two Voyager space probes have expanded our knowledge of the solar system’s outer planets.
How then to summarise Voyager? As Stone observes “I felt that we were all in the tradition of Galileo. He was the first to see the moons of Jupiter and the first to apply an instrument [...]

VASIMR, rather than warp speed, best bet for reaching Mars

Posted by John Lampard on Monday, 5 October, 2009 to the technology subset

Former astronaut Dr Franklin Chang-Diaz has developed plans for a plasma rocket engine that could drastically reduce travel time around the solar system when compared to the rocket engines currently in use.
But once we have this capability, Mars isn’t really the only place that we can go. With a megawatt-class VASIMR, basically we will [...]

Of course we may not need to go to Mars, it might come to us

Posted by John Lampard on Friday, 12 June, 2009 to the comment subset

It seems not even the orbital stability of the solar system’s inner planets is a given. If Mercury, orbiting closest to the Sun, were to be dragged out of its current orbit by Jupiter (a situation that is somehow possible) all sorts of chaos could ensue.
Mercury is the key to catastrophe. It is especially susceptible [...]

Is a 300 year old storm on Jupiter finally abating?

Posted by John Lampard on Tuesday, 24 March, 2009 to the comment subset

There’s evidence that Jupiter’s Great Red Spot, a storm twice the size of Earth, which has been raging for the last 300 or so years, may be diminishing.
Observations of cloud cover over the past decade or so have suggested the huge, oval tempest was getting smaller as Jupiter’s climate changes. But such observations are tricky [...]
