          [7 mins of terror]It takes seven minutes for a vehicles to descend through the Martian atmosphere to the surface. The distance between Earth and Mars is always greater than seven light minutes when these landings take place, so by the time Earth gets the message that the vehicles has made contact with the atmosphere, it is already on the ground. Hopefully in one piece.

            [Silvertongue]

            Silvertongue is the first in a series named “Remnants of Magic”, and both the title of the novel and the series become readily apparent in the first scene. Speaking of the first scene, it's a big one at 100 pages spanning eleven chapters, but don't let that put you off - it's one hell of a scene. The story kicks you straight into the action and that first scene is a long and continuous battle - and the poor protagonist (Jon) hasn't got a clue what's going on or why…
          • Beyond Falcon's Reachplugin-autotooltip__default plugin-autotooltip_bigBeyond Falcon's Reach

            Beyond Falcon's Reach by Jay Northearn, is a mish-mash of high fantasy, gothic-horror, steampunk and electropunk, with a dash of semi-intelligent machine-learning AI's thrown-in to boot. Yet for all of this, the world Northearn has created is homogenous and holistic - two watchwords I'll bang on about until the cows come home, to anyone who'll listen. Giving everything in your world a place and a reason for being there is something that every writer should always keep i…

          [The Bluffers Guide to the Quantum Universe]

          The Bluffers Guide to the Quantum Universe is a very funny guide (read: hilarious) to things surrounding quantum mechanics. Who the major players were, how the major theories won out over each other... or didn't. Tons of interesting facts you can toss around at parties and make it look like you know what you're talking about when discussing anything to do with quantum theory, quantum mechanics, who was who…
          • Creation Machineplugin-autotooltip__default plugin-autotooltip_bigCreation Machine

            Andrew Bannister’s “Creation Machine” is the best novel I’ve read this year – and that’s saying something, I’ve read some of the best sci-fi novels from the last five years in the last ten months.

            The breadth and depth of his imagination is incredible. He’s created an entire artificial galaxy, given it character and taken us on a tour that is as exciting as it is varied.
          • Iron Godsplugin-autotooltip__default plugin-autotooltip_bigIron Gods

            Another novel of The Spin, and following on from Creation Machine, Iron Gods continues in much the same vein. There are intriguing and plausible characters, a spaceship AI that has had its lobotomy reversed, strange worlds and even stranger economic forces.
          • Stone Clockplugin-autotooltip__default plugin-autotooltip_bigStone Clock

            The third outing in The Spin series from acclaimed author Andrew Bannister, Stone Clock, has a dark edge to it. Already an accomplished writer, Bannister has taken things up a notch.

            His usual mélange of lucid and slightly demented imagination is in full force, and the array of modes of humour are all present and permeate the pages as if they’d been dipped in the stuff.

            [Hard-Boiled Wonderland]

            Chris Morton is a writer with a certain pedigree, having been shortlisted for a Guardian award, this story is his third novel and his first in science-fiction.

            It tells the story of a man (Maggie Flycatcher) who has almost certainly the most boring job in history: he's a lemon tree supervisor. The creative talent that can come up with such a pointless job is one that deserves some recognition, so it instantly grabbed my attention. Flycatcher's …
          • Colony One Marsplugin-autotooltip__default plugin-autotooltip_bigColony One Mars

            [Colony One Mars] [4.5 stars]

            Colony One Mars promises to be a fast-paced sci-fi thriller, and it certainly delivers. The prologue is short and sweet, and although it doesn't offer any story information that isn't in the story proper, it does set up the atmosphere for what is to follow. The tension ramps up very quickly and most unexpectedly, and everything changes before we've had a chance to grab our breath.
          • Colony Three Marsplugin-autotooltip__default plugin-autotooltip_bigColony Three Mars

            [Colony Three Mars by Gerald M. Kilby] [4 Stars] The third instalment in the saga is even messier (for the protagonists) than the previous two, ramping up the tension and the action, and making the solution even harder for the reader to predict. The cast of protagonists has grown a little, but that's fair because the cast of antagonists has too.
          • Colony Two Marsplugin-autotooltip__default plugin-autotooltip_bigColony Two Mars

            [Colony Two Mars] [4 Stars] Colony Two Mars picks up the story a few years after the preceding story, Colony One Mars left off. I really enjoyed the first instalment in this trilogy, but this is a much better, much stronger story. As the overarching story of the trilogy begins to emerge, Kilby's eye for a good story starts to pay dividends.

          This pair of novellas comes courtesy of Zombie Pirate Publishing, and indeed the stories themselves come from the publishing house's founders and resident editors, Sam M. Phillips (Into the Eye) and Adam Bennett (Phosphorus).

          Since they come as a pair it is necessary of me to review each in turn before giving an overall impression, and I've chosen the order they appear between the covers.

Near Earth Objects

Image © David A. Hardy www.astroart.org, reproduced by kind permission

The following data is reproduced from the NASA NEO (Near Earth Object) database, and is updated daily. Each record represents an object such as an asteroid or comet, and notes the date and approximate time the object is closest to the Earth as it passes by. The data is refreshed daily covering the period displayed on this page.

There are 4 tables and 2 graphs:

  1. 10 closest passing objects today->28 days ahead
  2. Objects passing by the Earth today
  3. Objects passing by in the next 28 days
  4. Objects that passed by in the last 7 days
  5. Graph for a 36-day period up 20 million km
  6. Graph for 15-day period up to 1 million kilometers

With each record, there is a link to a JPL page that offers more information on the object. Records are ordered by date and time. Distances are rounded to the nearest kilometre. Object diameters are in metres, and are averaged from current maximum and minimum estimates. Magnitude is absolute magnitude.

Last updated: Wed May 12th 00:02

Scatter Graphs

The graphs show time in the horizontal direction, and distance vertically. For the upper graph, the period is the same period as the data in the rest of this document: 36 days (the last 7 days, today and the next 28 days). Each grid square is 1 day wide and 1 million kilometres high. The graph shows any object that has or will pass within 20 million kilometres of Earth.

The lower graph focuses on a 7 day period on each side of the current date, and a distance limit of 1 million kilometres.

Close approach data for locations other than Earth have been filtered out.
