Time to seek out a car wash. And some water would be good.

No doubt about it, the Curiosity Rover has totally lost that showroom shine.

Mars 3 Nil, Mars 1

April 13th, 2013

Emily Lakdawalla has posted a fascinating account, translated from the Russian original, of how a group of space enthusiasts combed images of the surface of Mars. Their aim: to find the Mars 3 lander that managed to transmit radio signals for 14 seconds back on 2 December 1971 before falling silent.

A Different Angle on Mars

March 25th, 2013

Posting at The Planetary Society, Bill Dunford found A Different Angle on Mars by looking back at images from the Mars Global Surveyor:

Like all Mars Global Surveyor shots, these are views of the Red Planet from orbit. What's different here is the highly oblique angle of these images. In each, the powerful Mars Observer Camera is not oriented straight down for maximum resolution, but off toward the horizon.

The result is a set of views that make me think of what it might be like to be at Mars, flying over the planet in person, looking out the window. Be sure to enlarge them, and see if you enjoy them as much as I did.

I reckon the image of Olympus Mons is my favourite, just because it emphasises the sheer scale of the thing.

I know the various space agencies have to choose the sites where they land their probes so as to maximise both the chances of a successful landing and the amount of useful science they can do in their limited lifespan, but it'd be nice if at some point in the future someone could contrive to bring down a lander somewhere near the peak of Olympus Mons. The view from up there across the planet's surface would be a sight to see.

Mars Attacked!

March 2nd, 2013

Is it wrong of me to hope that Comet C/2013 A1 (Siding Spring) does turn out to be on course to crash into Mars in October 2014?

The last time we had a ringside seat for that sort of impact it was a lot further away and nobody but scientists got to watch it live.1 This time, just think of the pictures we'd get, live on the web, from the array of spacecraft we have in orbit and on the surface of Mars.2

Joking aside, I wonder how the sight of a comet impact on that scale, that close to home would affect our views of living in the solar system. Would NASA suddenly find itself with as much funding as it wanted to design and build a comet deflector, just in case, not to mention greatly expanding existing tracking systems aimed at spotting comets while they're still way out there where there's time to nudge them away from Earth? Or would the remote chance of there being two such large-scale cometary impacts on the inner solar system in our lifetimes persuade us that we'd dodged that particular bullet and could leave the problem alone for a generation or two?

  1. Or as close to 'live' as the speed of light would allow.
  2. Alternatively, the Martian Defence Force is going to provide us with unequivocal proof that there is life on Mars, as we watch the Martian Robert Duvall and his crew set out on a mission to blow Comet Siding Spring into two pieces that will pass neatly on either side of their planet. Alternatively, it'll be the Martians from Mars Attacks! who'll step in and deflect a chunk of the comet. Of course, they'd probably do so in such a way that the comet would pass by Mars, only to cannon off Phobos at an angle that left it heading right for Earth. Ack! Ack! Ack!

Phobos eclipse

September 15th, 2012

A partial eclipse of the Sun by Phobos, as seen by the Mars Curiosity rover.

Not the most spectacular astronomical image you'll ever see, and not even all that rare an event,1 but even so it's pretty cool that we have a one ton, nuclear powered robot present on the Martian surface to beam the picture back to Earth.

  1. Phobos orbits Mars every 7 hours and 39 minutes, so there are frequent opportunities for it to get between the Sun and some point on the Martian surface.

1 minute to go…

August 6th, 2012

It turns out that as Curiosity was coming in for a landing this morning, NASA's Mars Reconnaissance Orbiter was watching.

I've seen CGI simulations of Curiosity's Seven Minutes of Terror before, but it does no harm to be reminded of just how insane a ride the Curiosity rover is going to have on the 5th of August when it lands on Mars.

I know there's no way NASA could afford to do it, but it's a shame that they couldn't have landed a smaller, simpler lander in the vicinity of the landing site just before Curiosity is due to descend from orbit. A lander with just one job: providing us with real-time moving pictures of Curiosity coming in to land. Fail or succeed, it's going to be quite some spectacle, and it's a damned shame that we're never going to get to get a proper look at what happened.

Barchan dunes

APOD: 2012 April 22 – Flowing Barchan Sand Dunes on Mars.

A Martian monster

April 11th, 2012

A Martian dust devil. That's a 20 kilometre high Martian dust devil.

If Andrew Stanton & co ever get to make a sequel to John Carter I trust they'll have one of these make a cameo appearance.
