#MarsWalk Day 113, 668.7 km

#MarsWalk Day 113, 668.7 km

No bicycling this week, and busy with various things, so I was back down to my typical 40-ish km for the week.

Unless you want to make note of 666 km, there’s not much of interest to talk about. The Martian terrain here is uninteresting… in fact, maybe interestingly uninteresting. I’m about in the middle of this:Screen Shot 2016-04-29 at 9.25.44 PMThat’s not a photo, it’s data from MOLA, the Mars Orbiter Laser Altimeter, on the Mars Global Surveyor spacecraft; I screencapped it from JMars. There’s some intriguing channels or something to the west, and rougher terrain to the east, but in the middle: smooth. Flood plain or something?

#MarsWalk Day 106, 627.4 km

Turns out my activity was curtailed only for about a day. After that I was fine and the weather was good, so I got out on the bike Sunday and Monday and did more walking than usual. I ended up with my highest distance week so far. Other milekilometerstones:

  • Saturday was Day 100
  • Passed 600th km on Tuesday
  • 20% of total distance on Thursday

The Mars terrain continues to be rather uninteresting. Here’s a 3D stereo image of a no name crater about 95 km to the west, imaged by HiRISE. Diameter’s about 3.7 km.ESP_016797_2170_ESP_016164_2170_RED.browse

#MarsWalk Day 99, 560.6 km

I thought I was not covering much ground last week except for Friday, but this week I had three days shorter than any of last week’s. And right now I’m dealing with a minor foot issue, so my walking and bike riding will probably be curtailed the next several days.

So I did about 36 km across… well, Mars, but not especially interesting Mars. Sorry. Wait, why am I apologizing? Mars should be apologizing.

Eleanor Lutz has drawn a beautiful thing which she calls “A medieval map of Mars” although, to quibble, it’s not all of Mars, and it looks more like 17th century than medieval. It covers longitude 50°W to 50°E and 55°N to 55°S, so unfortunately my MarsWalk is not on it. You can buy prints, etc., from her site.

#MarsWalk Day 92, 524.2 km

#MarsWalk Day 92, 524.2 km

It’s been a cold week, with rain in the middle and snow on both ends. In fact I think we’re ahead of the normal snowfall for the entire month of April, and there was one day with a record low temperature. Not so bad weather compared to a lot of January and February, of course, but colder and precipitationier than I really wanted to deal with in April… especially after that near 80°F day last month.

So I made kind of a poor showing most of the week, and then out of shame today I went on a longer than usual campus walk and ended up with, I think, my second longest distance walking day (tied for third longest distance day walking or biking) since I started. Which wasn’t enough to avoid a below average week, but it prevented a worst week ever.

I passed my 500th kilometer this week, though, and completed my third month since starting.

In my virtual neighborhood on Mars, for sufficiently large value of neighbor, there’s a crater about 100 km to my east; looks to be about 19 km in diameter. It has no official name, apparently. HiRISE has taken five pictures (one, two, three, four, five — follow the links for the full pictures, the pictures on those pages are just small details), two of which form a stereo pair. Get out your red/blue glasses. Here’s a cropped, low resolution version. Click on the image for the huge, higher resolution original:PSP_002266_2190_PSP_002411_2190_RED.browse copy

Check out those gullies.

#MarsWalk Day 85, 486.6 km

I put in more distance this week, slightly more than average in fact, though it felt like less.

Nothing particularly interesting on the way, though, in either my real context here on Earth (mostly on and near campus) or my virtual context on Mars, where I’m roughly paralleling a north-south stretch of Hrad Vallis. No very interesting sights to see. I’m in roughly the center of this Context Camera image. Yee ha.Screen Shot 2016-04-01 at 9.01.48 PM

It’s been a long March. (See what I did there?) I covered a good bit more ground last month than in February, partly but not entirely thanks to those two bike rides before the weather got seasonal again. (A couple inches of snow forecast this weekend! Way warmer than Mars though.) Since the start I’ve averaged 5.74 km per day, at which rate I’d finish on March 30, 2017… two days less than a year from now. But I expect to do better, what with warmer weather and more bicycle rides coming up.

#MarsWalk Day 78, 445.2 km

Today I logged a sluggish 1.2 km. Worked from home, didn’t go for a walk, didn’t do anything involving much walking. The whole week was below average distance.

But I’ve crossed Hrad Vallis. This is a channel, 825 km long, whose name derives from the Armenian name for Mars.

It may have been created by water, created from ice that melted due to magma associated with the volcano Elysium Mons. On the other hand this paper proposes it might have been cut by low viscosity lava flows.

My path this week started near the upper edge, left of center, of this MRO Context Camera image and went almost due south almost to the bottom edge, crossing the channel on Tuesday close to where those two prominent craters are.

#MarsWalk day 71, 411.6 km

I’m now more than 400 km from the start.

There’s stuff of some interest just ahead but I’ll save that for next week. For now I’ll just mention about 74 km east and a little south of my location there’s a fresh impact — the pretty obvious black blotch on this HiRISE image linked from this page. The impact happened sometime between February 2005 and March 2008. Screen Shot 2016-03-18 at 7.40.57 PM

#MarsWalk at Loja

Thanks to relatively warm temperatures in Syracuse last weekend, I got on my bicycle Saturday and Sunday for my first two rides of 2016 and my first two #MarsRides totaling 23.8 km. So I got a good bit of distance in, and as a result I was able to finish up today’s walking at my closest approach to the last of the small city craters: Loja, 10.4 km in diameter, named for a city in Ecuador. lojaIt’s further off than that last couple of craters, 59.6 km to my east. Loja’s been photographed three times by HiRISE: the western half once and the eastern half twice. Zoom in on the second of these three and check out the gullies on the crater rim.

Believe it or not, the next officially named crater I pass within 100 km of will be Gale — my destination, still about 2600 km away. There will be craters, but none with IAU approved names.
