We’re going to Mars again in 2016/More Curiosity updates
August 23, 2012
NASA announced that it has selected the InSight Mars lander for its next Discovery mission. (Discovery missions are NASA’s lowest cost tier of science missions, such as Kepler, Dawn, Messenger, Mars Pathfinder, and more.) You may be thinking, “ANOTHER mission to Mars? What for?” Well, despite all the awesome science that Curiosity will do, it can’t tell us much about the deep interior of Mars, or what Mars’ seismic activity is like. The InSight lander will be a stationary robot much like the Phoenix lander. In addition to measuring seismic activity, it will deploy a probe that will drill deep below the surface to measure the flow of heat inside Mars. These measurements will help scientists understand how Mars formed and what happened in the past that changed the surface from one of flowing water (and possibly life) to the barren dry wasteland it is today.

Curiosity completed its first set of driving maneuvers on Mars. This image was the first that showed the wheel tracks, confirming that the rover drove successfully. This was only a test of Curiosity’s driving systems, the first of several. Tests of every science instrument and every other system on the rover will continue for at least a month or so before they’ve established a solid baseline for how everything behaves now that it’s actually on Mars. Only then can the scientists begin run the real experiments the rover was designed to carry out. Science is sometimes very tedious and slow, but the results and knowledge gained is very much worth it.

NASA’s Curiosity rover has been one resounding success after another, and every step of preparation and equipment testing has gone perfectly. The latest success was an upgrade to the rover’s software programming, changing its computer from landing mode to roving mode. The process took 4 days, but went swimmingly. For more details on that visit this Discovery News article.
There have been enough high resolution images made available from the rover that photographer Andrew Bodrov was able to create this absolutely STUNNING 360 rotating panorama of the rover’s surroundings. Seriously, this is one of the coolest things I’ve seen in a while. Brodov used images from NASA’s other rovers Spirit and Opportunity for reference to add-in the sun and sky components.

It’s a great day to be a human. We just, you know, built a nuclear powered 1-ton robot, sent it into space a huge rocket on a trip to another planet, and landed it there with a hovering jetpack skycrane. Oh, and the whole hovering jetpack skycrane thing was all automated. NO BIG DEAL.
Everything went absolutely perfectly. And we even got back images from the rover just minutes after touchdown. Not only that, but I’ve seen tweets that the Mars Reconnaissance Orbiter was able to capture images of the capsule descending during its parachute phase. Those images should be out later today. In the meantime, here is the first image of the rover’s shadow. In the coming days we’ll have many amazing, full-color, high-resolution images of the surroundings.
UPDATE: The Mars Reconnaissance Orbiter did in fact get the shot of the capsule and parachute! Just consider this a victory lap for NASA. Check it out:
NASA’s Curiosity Rover lands on Mars Sunday night
August 2, 2012
You’d have to have been under a rock to no know that NASA’s latest and greatest Mars rover is about to land on the Red Planet. It’s been all over the news lately… but here are a few more deets that you may not know, including when and how to watch the coverage.
As usual, Universe Today is on top of the coverage, and this infographic was particularly interesting. They will also be teaming up with Google, CosmoQuest, and the SETI Institute to do a live webcast via Google+ to cover the event. Among the cast of hosts is one of my favorite fellow science enthusiasts/skeptics Dr. Phil Plait of Bad Astronomy. That begins at 10pm central time. The actual landing is scheduled for 12:31am central time. For more on the webcast check out the post on Universe Today.
Some random cool facts:
- This is the most complex landing procedure ever carried out by a NASA interplanetary mission.
- The supersonic parachute that slows the lander during the descent phase is a whopping 51 feet in diameter.
- The rover itself is about the size of a Mini Cooper.
- The rover weighs 1,982 pounds (on earth… on Mars it weighs about 747 pounds)
- The rover is powered by a small nuclear reactor.
- Curiosity will land inside Gale Crater, near the base of Mount Sharp, which has layers of exposed minerals that the rover will sample and study.
- The total cost of the mission is $2.5 billion.

NASA has officially given up efforts to contact the presumably dead Mars rover Spirit. Things started going downhill for the rover back in the Spring of 2010 after attempts to free it from a mound of sand were unsuccessful. The rover was in a bad position for its solar panels to absorb power from the sun, and with the impending martian winter, engineers put Spirit into a sort of “hibernation” mode. They feared that the rover didn’t have enough power to run its heaters which protect the circuitry from the -125 °F temperatures that can occur during winter. Those fears appear to be correct, because now that we’re well into the Martian spring (for Spirit’s location), the solar panels should have collected plenty of power to run the communications equipment. But the rover has been silent for several months now, and the engineers believe the rover is truly dead.
The good news is that Spirit’s twin, Opportunity, is still going strong on the other side of the Mars, with no problems whatsoever. And furthermore, the death of Spirit comes after over 6 YEARS of operation. Loads and loads of valuable data have been gained from the rover, and it has lasted 25 TIMES its expected lifespan of a few months. I’ve said it before and I’ll say it again, these twin rovers are arguably NASA’s second greatest achievement, behind putting a man on the moon. For more, read Phil Plait’s post on this, or go straight to the source, NASA.

You’re looking at an important piece of history when you look at the above photograph. That’s the first ever image of Mercury taken from orbit. NASA’s Messenger spacecraft successfully entered stable orbit around the solar system’s smallest planet, and yesterday morning we got the first images taken from said orbit. The spacecraft has taken other images of Mercury as it approached, but Messenger just recently actually entered a permanent/stable orbit, and will remain there for at least a year, studying this hot, battered planet in unprecedented detail. This is also the first time any spacecraft has orbited Mercury to begin with. (Via Discovery News)
In some other space-related news, NASA decided to pull the plug on James Cameron’s idea to install a 3D camera on the next Mars rover mission, Curiosity. Honestly, I love this idea, as it would have allowed anyone with 3D glasses to watch cinema quality footage from the surface of Mars. When you really think about that, it’s absolutely mind-boggling: 3D video footage from another planet. However, NASA felt that since this rover is already way over-budget, the risk of failure was too great because the cameras haven’t been thoroughly tested. I’m certain that this technology will end up on another NASA mission to Mars in the future. So just wait. In another 5-10 year’s we’ll be looking at HD footage from Mars in 3D. NBD… (Via i09)
I’m back, here are some cool links

Eating lunch with the Darlins in the Bronx.
So I’m back! It was a blast and I’d do it all again in heartbeat. I don’t have time to give a full rundown, but quite possibly the most memorable moment was realizing that a tornado was hitting Brooklyn while Those Darlins were soundchecking in Bowery Ballroom. Here’s the official weather report from the NWS. Needless to say, tornadoes are pretty rare in NYC. Thankfully we were in Manhattan while all this was happening. Those Darlins have some great new songs on their new record, and their setlist for this tour is mostly those new songs, peppered with the favs from their debut, and the free single “Nightjogger” which you can download at the Nashville Cream. Basically they’ve taken on a bit more of a pure rock & roll character, and drummer “Sheriff” Linwood Regansburg has taken on a much more prominent role in the songwriting, and even sings on one of the new songs, though they’re not yet playing that song live. Stay tuned for more on them and more on the results of my photo documentary project.
Meanwhile, here are some awesome things I came across while catching up on all my RSS feeds:
Vaccines absolutely, beyond a shadow of a doubt, do NOT cause autism. A new study explored every possible way that thimerosal containing vaccines (TCVs) could be linked to autism and there was none. Absolutely no connection whatsoever; the same findings as the many other studies that have been done to investigate the claims of the anti-vax crowd. In fact, the result hinted that the administration of TCVs between birth and 7 months may actually reduce the risk of autism. It’s very simple, get your kids vaccinated! If you don’t, you are a threat to public health. Vaccines are one of mankind’s greatest scientific breakthroughs and have saved countless lives. There will always be a miniscule (and utterly negligible) risk of a bizarre allergic reaction or other complication, as there is with any medication or vaccine, but that risk is far, far, FAR outweighed by the benefits. And those risks have now been proven once and for all NOT to include autism.
A pair of astronomers have made an official prediction that the discovery of the first truly earth-like exoplanet will happen in less than a year– May of 2011. They used a well-known methodology called Scientometrics to make this prediction. I’d venture to say that to me, nothing in the field of astronomy, or even science in general, is more exciting than the very likely possibility of life on other planets. The discovery of the first true earth twin is a major step in that path. I really hope this prediction comes true.
Five awesome facts about NASA’s next robotic mission to Mars, the Mars Science Laboratory (a.k.a. Curiosity) which will launch in late 2011.
23 amazing photographs from the 1940s and 50s of nuclear bomb tests conducted by the US Military. This New York Times photos series is utterly fascinating, mainly because of images 5 through 7. Most of us have seen plenty of images of the mushroom clouds created by nuclear blasts, but those 3 images are unlike anything I’ve ever seen before. They were taken with a super high-speed camera and literally captured the blast at the very instant the explosion began. If I saw this image out of context I would probably think it was a microscope image of some sort of virus. The amazing irony here is that both a virus and an atomic bomb are incredibly destructive, yet in such completely different ways.
The actual scale of the observable universe, from the smallest possible thing the largest possible thing, is utterly impossible for the human mind to comprehend. Mathematicians came up with the concept of “orders of magnitude” to help with this, but I say it’s still impossible for any human to really grasp. But this fun little interactive Flash animation is pretty cool way of displaying the concept. (Via Dr. Neil deGrasse Tyson’s Twitter)
Magic Kids get signed/Monotonix singer injured
January 29, 2010
At a party in Murfreesboro several weeks ago I ran into an old acquaintance from college- Alice Buchanan. She’s from Memphis and had been in a band called Scandaliz Vandalistz which may or may not still exist… but when I talked to her she told me of this new band she’s involved with called Magic Kids that had just formed and were already gearing up for a tour with Girls. I was astounded at the speed of their ascent to label-signed status. As gorilla vs bear, Nashville’s Dead, and the Matador Records blog all report, they just signed to True Panther. Their quick emergence is not unfounded, though, as it’s literally impossible to deny the warm-fuzzy-feel-goodness of “Hey Boy.” It’s very summery, fun, and has the ability to turn even the dreariest winter day into a breezy summer afternoon. The first two bands that come to mind when I hear these songs are the Beach Boys and I’m From Barcelona. Grab two mp3s at Nashville’s Dead. Then just try to keep from putting them on repeat. I dare you. They’ll be playing at the Exit/In on Feb. 6th with Girls, and also hitting up SXSW in March. I’m sure they’ll be on my “must-see” list.
Monotonix singer Ami Shalev’s luck finally ran out at a show in Florida Wed. night. Though Brooklyn Vegan’s headline says he broke his leg, the statement from the band doesn’t quite make it that clear. Seriously dude, you should’ve expected this to happen sooner or later. You just can’t do crazy shit like that at shows without getting hurt eventually. Hopefully they’ll be able to resume melting faces soon enough.
As for this weekend, I’ll be attempting to get to the super-exclusive Clipse show at Phatkaps, but the snow/ice-gasm 2k10 may prevent it. The roads should be clear by tomorrow night, though, for the Wax Fang/How I Became the Bomb/Non-Commissioned Officers show at Exit/In.
And, given my post yesterday about the Mars rover Spirit, I must share this adorable comic from xkcd:
Skydiving from space/NASA Spirit rover stuck for good
January 27, 2010
Back in 1960, a man named Joe Kittinger did probably the ballsiest thing ever done by any human being. EVER. He jumped out of a balloon that had lifted him literally to the edge of space- 102,800 feet above sea level. That’s roughly 20 miles. Not only was it by far the highest skydive (space-dive?) ever, but he also set a record for the fastest that a human being has ever traveled outside of a machine. Because he was free-falling through such thin air during the first few minutes of his jump, there wasn’t nearly as much friction to slow his fall, which allowed him to free-fall at supersonic speeds. Yes, he was traveling faster than the speed of sound, with nothing but a pressure suit around him to keep him alive. I can’t think of anything more utterly badass than that. Now a couple of people are trying to break Joe’s record by jumping from an even higher altitude. Frenchman Michel Fournier and Austrian Feliz Baumgartner are both attempting to make these jumps this year, according to an article on Discovery.com. Some would say these guys are totally crazy, but I say they are total badasses, and envy them. Watch Joe Kittinger describe his experience in this video:
NASA’s Mars rover Spirit will now become a stationary asset. The twin rovers Spirit and Opportunity were launched in 2003, and successfully landed on Mars in 2004. They were only intended to operate for 90 days, yet amazingly they have lasted 6 years. The news that NASA has abandoned efforts to free the Spirit rover from the pit of sand in which it’s been stuck for the last 6 months is somewhat saddening, but in context, it really doesn’t matter at all. These rovers are quite possibly NASA’s 2nd greatest accomplishment, next to putting a man on the moon. We should only be thrilled that this amazing little robot lasted as long as it did. Its mission is far from over, however, as it can still do plenty of science sitting right where it is. Of course, Opportunity is still mobile and NASA continues to drive it around, exploring new territory. Who knows how long these things will last? I have a strong feeling the abrasive dust that now coats almost every inch of both rovers will eventually take its toll, but how long that takes is beyond me. For more check out this article on Space.com. Here’s a cool animated GIF showing the last few maneuvering attempts to free it from the sand dune:

First of all, I can’t even explain how awesome the Those Darlins album release show was saturday night. They TORE IT UP! Go look at the tons of pics I took, and read the great review over at Nashville Cream. NOW. Then go check out the new Lake Fever Session featuring Hung Up On Me, Snaggletooth Mama, and DUI or Die.
Something else that blew my mind: reading that MGMT will be opening for Paul McCartney for two dates at Fenway Park in Boston. One year ago if you had told me MGMT would be opening for Paul McCartney I’d have laughed in your face. What a difference a year makes… (Via Brooklyn Vegan)
Spoon have been in the studio again, and already have new material coming out in form of an EP called Got Nuffin. Stereogum posted a link to Amazon this morning where you could stream it, but for some reason Amazon has since taken that down. No matter, it’s always good to hear new Spoon material. They have the uncanny ability to just keep on making good music, and they don’t seem to be stopping anytime soon.
For your daily eye-gasm, take a look at the Boston Globe’s Big Picture blog. I’ve linked to this blog several times before, as well as posted photos from the International Space Station, but I challenge you to ever tire of such beautiful imagery, because you can’t. Today’s post includes the image I posted last week of the Russian volcano, along with 34 others. Feast your eyes.
The Spirit and Opportunity twin rovers that have been operating on Mars for a mind-blowing 5 years now are starting to show their age. Spirit has been stuck in some sandy dirt for a couple of weeks and engineers are having quite a time trying to get her free. They’ve even created a website called “Free Spirit” to chronicle the progress being made. Basically, they have to take different types of dirt from earth and blend them together to simulate the martian soil as closely as possible, then build a dummy replica of the rover and try to position it exactly how the real rover is positioned in the dirt. No one at NASA ever dreamed that these 2 rovers would last this long (the original mission plan was for only a few months!) so it’s not a huge loss if they can’t get her free. At least Opportunity is still in good shape.
