I’ve come to the hard decision that it’s time to put Steve Cross Loves Music and Science to rest. Don’t worry, I still love music and science! I just don’t have time to blog about it anymore. The natural progression of life, relationships, commitments, etc… has forced me to re-organize priorities. That’s not a bad thing, it just means that blogging has to take a backseat to more important things. So, this is the end of this blog! I’ll keep the domain for the foreseeable future, and everything will remain archived as-is. Everything has a a life cycle, and this blog has reached the end.
This is not the end of me sharing this type of content on the internet, however! I do intend to share more science articles, links, tidbits, etc… on my Facebook and Twitter feeds, so follow me there. This will allow me to still share my interests and love of music & science with whomever is willing to listen. I’m also on Instagram, so follow me there for more visual content.
I also have other blog ideas that I’ve been milling around for a while, but I’m keeping that under wraps until I officially decide what I’m doing. If and when that comes to fruition, it will be made public via my Twitter and Facebook.
Whether you’ve just started following me or have been for many years, I hope you learned something, gained something, or otherwise benefited from this blog!
NASA’s Curiosity rover is back to work on Mars, after a few weeks of radio silence due to Mars’ being behind the Sun from Earth’s perspective. The photo above shows a new hole created by Curiosity’s drill, and scientists hope that the analysis of the samples taken from this hole will match up with, or at least support, the exciting results of the previous drilled rock analysis back in February. Those results suggested that Mars’ surface was once habitable for microbial life as we know it. The results of the analysis will no doubt be released in the next few weeks, before Curiosity begins the long drive to its ultimate destination, a huge layered mountain known as Mt. Sharp.

Warning: If you are one who is prone to getting sucked into rabbit holes of Wikipedia links and losing all sense of productivity, I highly recommend you DO NOT read this article while at work! Wikipedia has a really awesome, really addictive list of common misconceptions. Don’t say I didn’t warn you! (Via Kottke.org)

Here’s a quick roundup of some interesting stories and headlines that have popped up in the science world recently:
- Based on new calculations using information from the Higgs Boson discovery last year, some physicists are worried that the universe might be doomed for boredom. The new math shows that the very existence of everything could be inherently unstable, and in a few tens of billions of years a tiny bubble of an apparently much more boring, alternate universe might pop-up and subsequently expand at the speed of light, destroying everything. Granted, there’s still a lot to learn about the Higgs, the equations used to make this prediction will improve drastically over the coming years, and the human race probably won’t be around to see this happen, but I can’t help but laugh thinking about the universe vaporizing into a more “boring” state of existence.

- I wish I had time to cover/post about the Russian meteor explosion this past weekend, but I was out sick Friday and had a very busy weekend/early week of moving in with my lady Old Red Boots. You probably know the basics- a medium-sized meteor entered the atmosphere over Chelyabinsk, Russia last Friday at about 9:20am local time. I just want to point out the important facts: (1) The Russian meteor explosion had nothing to do with the close fly-by of asteroid 2012 DA14 which happened later that same day. The trajectories/orbits of the two were completely different. It was simply a bizarre coincidence. (2) The damage to buildings and glass was caused by the massive sonic boom, as well as the actual explosion of the rock itself high in the atmosphere. The sounds and damage were NOT from the impact of the meteor hitting the ground. There’s tons of footage of this thing, but this video has the best audio I’ve found– if you have a subwoofer, turn it up and you’ll get some sense of the earth-shattering rumble. This video is long but shows both the bright streak of the meteor (about 4:30 in) and has the ensuing sonic boom (about 7:00 in). (3) NASA estimates the meteor was about 55 feet across and weighed between 7,000 and 10,000 tons. (4) A large chunk of the space rock is believed to have landed in Chebarkul Lake near Chelyabinsk, gouging a large hole in the ice. Phil Plait of Bad Astronomy had great coverage and follow-up of this event, so be sure to check those posts out as well!
- Dennis Tito, the first space tourist, wants to put humans on Mars in 2018, and he’s created a non-profit called the Inspiration Mars Foundation to do it. I have to be honest, the timeframe of this sounds absolutely crazy to me. Not many details have been announced, but apparently there will be a press conference next Wed. Feb. 27th in which more details will be revealed, so I’ll try to withhold my skepticism until then, but it’s hard. (Via Universe Today)
- Astronomers with NASA’s Kepler Mission have found the tiniest exoplanet yet, orbiting the star Kepler-37 about 200 light years away. This planet is significant because it’s even smaller than our own Mercury, and just barely bigger than Earth’s moon! Finding a planet that small is a major milestone and huge accomplishment for the Kepler team. I’ve no doubt they will be finding the Holy Grail of planet-hunting, a true Earth twin, within a year or two. (Via Bad Astronomy)

This is an interesting short documentary episode from Vice’s Motherboard series on Copenhagen Suborbitals, a self-proclaimed “open-source, do-it-yourself space endeavor” started by two really smart guys in Denmark. Basically they want the world to realize that getting to space is actually a very achievable thing for average people if they really truly want to do it. It’s an awesome idea and one that I applaud whole-heartedly. Just watch and be amazed at what these guys have accomplished so far with their DIY approach.

This video clip shows some of the amazing footage from Felix Baumgartner’s chest and head cameras during his successful supersonic skydive attempt Sunday. I’m sure you’ve heard most of this by now, but the preliminary numbers are 9 minutes & 3 seconds jump to landing, top speed of 833.9 mph or Mach 1.24, jump height of 128,100 feet, and freefall time of 4 minutes & 20 seconds. He broke all the records previously owned by Col. Joe Kittinger (who was a consultant on the mission and coached Felix through the whole jump) except for one: longest freefall. Presumably this is because he fell so fast. The faster you fall the shorter your freefall time will be. Felix entered a terrifying spin during the first part of the dive, but he managed to regain control and did not have to deploy the emergency stabilization chute, which would have prevented him from breaking speed of sound.
In other science-related news, photographer and videographer Christopher Malin created a surreal new type of timelapse that I’ve yet to see used on space station footage- a stack. Stacking involves blending each frame of the footage into the next, creating a blurred effect with light trails and star trails. Just watch it, it’s kind of a head trip:
A combination of technical problems and gusty winds caused Feliz Baumgartner’s record-breaking 23-mile supersonic skydive attempt to be aborted just as the balloon was being inflated today. They had a good window of calm winds to work with, but weren’t able to get the balloon off before a gust of wind came along and blew parts of the partially inflated balloon onto the ground. This is a dicey situation, because the balloon material is so delicate and folded so meticulously that once it’s been unfolded, it cannot be deflated and used again. As far as I can gather from what was said during live webcast, they only have one backup balloon. Since this is the largest balloon of its type ever made or used, it’s REALLY expensive, so they really have to get it right on the next attempt.
The air at the surface, and for roughly the first 1,000 feet off the ground, must be absolutely still for the launch to happen safely. Even a little bit of crosswind can take the balloon off course, dragging the capsule across the ground or smashing it into anything nearby, just as NASA learned first-hand a few years ago during this failed balloon launch in Australia.
Just a quick roundup of some news and updates in the science world:
- Felix Baumgartner’s supersonic, record-setting skydive attempt was delayed until Tuesday morning due to weather concerns. The balloon launch is scheduled for around dawn, so I’ll try to tune into the interwebs tomorrow morning to see how it goes. More at Discovery News.
- Space X successfully launched its first official, non-demonstration mission to the ISS last night. The launch was successful despite the Falcon 9 rocket losing one of its 9 main engines about 90 seconds into the launch. The faulty engine was immediately shut down and the onboard computer recalculated the flight trajectory, adding the necessary burn time to get its Dragon capsule to the correct orbit to rendezvous with the ISS. Phil Plait at Bad Astronomy has the full deets.
- The Mars Rover Curiosity successfully scooped up a sample of soil and agitated it in a bin this past weekend. Instruments on board will soon run a series of tests to determine if the soil could have supported microbial life in the past. Check out this video created from a couple hundred photos taken of the sample as it was being agitated.
