Smallsteps Wallpaper: Luna 17 & Lunokhod 1
Sunday, September 9th, 2007More than a year after Americans set foot on the moon in 1969, the Soviets landed the worlds first remote “rover” type vehicle ever to explore the surface of another world. One almost has to wonder how the politics of this mission even played out to bother even letting it continue. It would hardly seem worthwhile sending a robot to do the work actual humans would be conducting 5 more additional times beyond the historic Apollo 11 landing from the year previous.
The rover was named “Lunokhod” and translated means, “Moon Walker”, it carried out a mission for 11 days and traveled 10.5 km. Despite the fact that nobody knows exactly where the rover rests today, the rover and lander were sold at auction in 1993 for $68,500. The auction catalog read that it was, “resting on the surface of the moon”.
Smallsteps Wallpaper: Luna 3
Sunday, September 9th, 2007The Soviet spacecraft Luna 3 was the third such craft to be successfully sent to the moon in history. The images were not very great, as can be seen… but it was the first glimpse mankind ever had of the side of the moon that is permanently facing away from us. With the first look at the “dark side of the moon” many people were quite excited and the images were published the world over. It took a total of 29 pictures and was able to image at least 70% of that unseen side of the moon.
The image is largely intact but for the purposes of presentation I faked the “8” in the number on the bottom and actually added some noise lines.
Smallsteps Wallpaper: V2 Rocket
Sunday, September 9th, 2007While looking at all the strange images from old Soviet moon missions on Don Mitchell’s site, I thought it would be interesting to design a set of wallpapers from these early images. I call the series “Smallsteps” as in Neil Armstrong’s famous, “One small step…” quote from Apollo 11. Obviously, there would have been no “giant leap” without a large number of these other “small steps” preceding the Apollo Program (although some of the images I have planned actually come after or during the Apollo program).
To me, the fact that the human race was even doing space exploration back then seems almost out of time — and then you look at the spacecraft that were sending back these images and it is amazing that anything really ever worked. Tin cans with cameras sending back images that were often just as bizzare and rough as the vessels that carried them. It is even more incredible when you consider that people eventually started strapping themselves to these rockets and floated around the vacuum of space in boxes wrapped with foil.
Seems appropriate enough to start the whole set off with the V2 images of Earth sent back in the shockingly early year of 1948. According the the Air and Space Museum these are the first images of the Earth taken from space in history. The image itself I suspect was just scanned from some print and the number tags and directionals are original (although there were about 17 of them and I removed a majority of them in Photoshop).
Martian Skies Will Clear Up
Monday, August 20th, 2007Put on a happy face.

The robotic arm on Spirit has begun operations again. The dust storm has been breaking up and allowing sunlight to recharge its batteries enough to resume some scientific activity on the surface. Apparently things are not quite so clear yet on Opportunity’s side of the planet, but it is starting to look as if things will be back to normal soon enough for Spirit at the very least.
Wallpapers: Earth from the Space Shuttle
Saturday, August 18th, 2007Something impressive seems to be happening on STS-118 (the Space Shuttle mission currently in orbit)… Photography.
Surely there are many excellent images to be had from previous Shuttle missions, but the images coming from STS-118 are really something to see. Perhaps one of the astronauts doing the EVAs (extra vehicular activities) has a degree in photography? At any rate, this site’s recent effort to give Earth it’s fair presence on this site has to take advantage of some of these fantastic images coming from NASA.

Phoenix Lander ready for launch tomorrow. Its destination is the Martian Arctic Pole, hopefully realizing the hopes of the lost Mars Polar Lander. See website for news.
The Mars Laser and the Future of Space Exploration
Wednesday, June 27th, 2007![]()
The coming Mars Science Lab mission will be employing a most unusual device for examining the surface of another planet. When MSL reaches Mars around 2010 it will be rolling about the surface of Mars zapping rocks and soil with an on-board laser beam generator. The beam is part of a science package that practices laser-induced breakdown spectroscopy, or LIBS for short. First, scientists on the ground will determine which objects or features imaged with normal on-board cameras seem worthy of further examination. Once a target is selected, a beam is generated and focused upon a small area of that target. This will burn or superheat the material into a plume of particles that expands at supersonic speeds as it cools. It is at this cooling time that the spectrometer will image the cloud and use the widest range of electromagnetic wavelengths possible — from infrared light through visible light and all the way to the ultraviolet. Since every element we know of has a signature of some wavelength within that wide range, the spectrometer will be able to determine all the materials present in the sample (even to simple trace amounts) by detecting and imaging the specific wavelength signatures present in the cloud.
What is most exciting about the instrument is that it is yet another example of NASA really employing non-traditional methods of exploring space. Gone are the old flyby probes of the 70’s and 80’s that simply pick a target and speed by with 95% of its mission goals completed in hours. So far this decade, NASA has chased a comet and collected comet dust in a grid of aerogel; intentionally slammed a heavy probe into a comet to form a man-made crater; they delivered 2 rovers to the surface of Mars that got there from a bounce landing; performed an impromptu landing of a non-lander type probe on the surface of an asteroid and now we will be shooting rocks on Mars. It provides us hope that once we are through the current financial speed bump of retiring the Shuttle fleet and completing our International Space Station commitments we can expect some really exciting new missions to our extended Solar System family. Some have already suggested such missions like air-probes on Mars and Saturn’s Titan; more aerogel collector type missions at Saturn’s Enceladus to collect geyser dust and most exciting of all would be a tunneling probe that could melt its way through the icy crust at Jupiter’s Europa in order to release a submarine type probe into Europa’s vast underground ocean.
It is stunning when you consider the near perfect scorecard for NASA’s unmanned space missions in the last 10-15 years and yet the organization is currently saddled with the image of being ineffective, stodgy and even sloppy. All these perceptions are coming from the manned side of its operations which hasn’t really done anything inspirational since apollo and the initial shuttle years. If only NASA was able to transfer some of the bold ambitions of the unmanned wing of its operations to the manned side of things, then maybe this image could just go away. I propose that even with the occasional tragedy and loss of life (which is inevitable on such endeavors) people would be much more accepting of such losses if astronauts died in the pursuit of doing something remarkable like going to Mars or even the moon for a second time. I mean, who wants to die so that we might hand deliver another component to the space station?
It is high time for us to be inspired by something again… on a grand scale. Time to focus at least some of our attention on something other than the fear of being blown up by terrorists or waging another war on a culture we know so little about. It is truly time to forget about Paris Hilton, forget about reality television and all the other pointless distractions that keep us from dreaming. In many ways it is bigger than just doing science in space — we need to give the next generation something better to think about. Something so exciting that the trivialities of the day that seem to dominate the national consciousness will at least be challenged by something so great that it will be hard to ignore.
We need to get going.
Mars Science Lab Animation
Wednesday, May 30th, 2007The coming Mars Science Lab mission video is available with various resolution options here (they are also downloadble!). This animation doesn’t focus as much on the trip to Mars as the MAAS ones have in the past, I would imagine that NASA wanted to highlight all the advanced science this mission will be performing instead of focusing on the long cruise to get there.
Take a look especially at the part of the mission where apparently they actually shoot a laser beam at various targets and take measurements of, what I would imagine, are the gasses emitted from such a burn. It also illustrates the process by which MSL will be taking soil and rock samples for in-depth investigations. This mission is exactly what it claims to be… a roving Science Lab on Mars. This is as close to having astronauts on the surface as our current technology can allow… that is… without actually sending someone… which our current technology does allow.
Stardust Extended Mission Target Is…
Tuesday, April 24th, 2007Soon after the Stardust mission flew in close and collected tiny samples of comet dust in Jan 2004 from the comet Wild 2, the spacecraft was placed into hibernation mode – only to be awakened for occasional health status calls.
A proposal to extend the mission into Stardust-NExT suggests the spacecraft be sent on a trajectory to encounter comet Tempel 1. The main objective of this mission would be to image the crater left behind by the Deep Impact mission of 2005. That mission did not manage to image the resulting crater due to the huge amount of dust blasted off from the impact (pictured above-left) which blocked the view until well after DI’s cameras were out of range to see any details on its surface. The final decision on this extended mission is expected this May/June and should it be approved… it is expected that Stardust-NExT would reach Tempel 1 at some point around 2010.
Return to the Moon Trailer
Tuesday, April 24th, 2007NASA has put out a “Return to the Moon” trailer at anon.nasa-global.edgesuite.net
I Drew the Cassini Spacecraft
Wednesday, March 21st, 2007So, I am tentatively planning to make a poster for the Cassini mission at Saturn. I always wanted to get a real nice graphic poster of some mission to Mars, Jupiter or Saturn… but the posters out there are always data driven and not so celebratory or artful. So I have decided to make my own and I started with drawing the spacecraft itself. I have no idea how accurate some of the instruments are as I was unable to find many visual references of them apart from the usual renderings.
Rosetta at Mars
Sunday, February 25th, 2007This gorgeous true color full globe of Mars may become the definitive Mars portrait image for the planet. For those may not have noticed, I have tried to apply a “portrait” label on at least one image per body as being the best representative full globe image of that world. The image I currently have tagged for Mars is that great image of Valles Marineris cutting across a near full disc of Mars taken by Viking.
Also worth posting is this semi-color image of Mars seen from behind the solar panels of the probe itself. It was taken by the lander attached to Rosetta which will one day detach itself from the parent probe and make an attempt to actually land on the surface of comet 67P/Churyumov-Gerasimenko in 2014. It looks as if it was originally a black and white image and someone at ESA just applied a color tone to the Mars globe, although I could be wrong.
Mars Reconnaissance Orbiter’s Got Good Eyes
Thursday, February 1st, 2007
This is a great way to truly understand the capabilities of the Mars Reconnaissance Orbiter. This image of Jupiter is taken from Martian orbit which is 357 million miles away. It is comparable to the what the New Horizons is seeing as it actually approaches Jupiter, which is currently 38 million miles away. So if you were wondering how MRO can get those incredibly detailed images of rovers and landers on the surface from orbit… now you can scratch your head and wonder how it can see Jupiter as good as a probe that is actually approaching a flyby in a few weeks.
Okay, so not as exciting a wallpaper as most… but it was taken from Mars and you can see (i’m guessing) is Europa, Ganymede and Callisto in the same shot.
Wallpapers: Three From Apollo
Friday, January 26th, 2007A few decades ago, about 12 men walked upon the surface of another celestial body for the first time in history. At one point, Neil Armstrong looked up at Earth and blotted it out with his thumb and thought the significance of that simple act. “That’s home. That’s us. On it, everyone you ever heard of, every human being who ever lived, lived out their lives. The aggregate of all our joys and sufferings, thousands of confident religions, ideologies and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilizations, every king and peasant, every young couple in love, every hopeful child, every mother and father, every inventor and explorer, every teacher of morals, every corrupt politician, every superstar, every supreme leader, every saint and sinner in the history of our species, lived there on a mote of dust, suspended in a sunbeam”. While these were not Armstrong’s words, but instead Carl Sagan’s, it is clear that it is along these similar lines he was thinking.
It is easy to forget how incredible those moments were as they happened so long ago, and the first of these was some months before I even existed as a person. We have grown accustomed to these images of men walking on the moon, in no small part because a follow up is so long overdue that they seem antiquated or quaint. So it seemed to me that out of 50 wallpapers uploaded it might be appropriate to include man’s first exploration of any of these places as part of the collection.
