When I started this blog I told myself I would use this space to talk about things that inspire me and highlight the best in human character. I want it to be more about building things up, and talking about what is possible, rather than tearing things down or endless snark, cynicism, pessimism, paranoia, etc. The headlines lately have been dominated by disheartening news, particularly in my home state of Wisconsin, but there have been some awesome things going on, which I want to spend time thinking about.a
There’s been some great press on the Ice Cube Neutrino Observatory lately, including an excellent article in IEEE spectrum. I had previously blogged about Ice Cube, and it continues to remain in my thoughts, how awesome this thing is. Every time I read dismaying political news or feel despair at the missteps of our society, I remind myself that we’ve got dudes at the south pole tracking cosmic rays, and I feel a little bit better about our species. It’s reassuring–maybe the large majority of people are too caught up in the hustle of daily-life to bother with such existential “big-questions” but there is a tiny group of people working to answer these questions for our behalf. Those people are called heroes.
Something else which is very, very cool is the STEREO spacecraft. Thanks to these guys, for the first time ever, we have a full 360 degree view of our sun. Sitting in same orbital position as earth, one satellite sped up and one slowed down, so that eventually (read:now!) they are positioned on opposite sides of our star. If I extrapolate correctly from the image above, it looks like from now and until around 2018, we can actually see the whole sun–enabling scientists to track sunspots, and the massive bursts of radiation that periodically spew forth. Although the odds of these radiation bursts and magnetic storms just so happening to align with Earth’s position are low, when it does happen, it directly affects all of our lives, in the form of blackouts, GPS interference, and slowdowns in many global industries affected by this radiation. The rotating image at right is the first 360 degree composite they made of the sun. There will be a lot more of these to come!
The STEREO satellites, to me, represent some small measure of mastery over our cosmic front yard. It’s good to have a window to know what’s happening outside. And it excites me to think that we’re doing it. Not only do we have the technology to do it (the most obvious barrier), but we also have the political willpower to spend them dollas to get up there and DO it (this is the real obstacle to most awesome science). That, my friends, is what you call rad.
I’ll sandwich in an honorable mention slash eulogy here for the NASA Glory satellite, which recently crashed into the Pacific. It’s a sad thing to think about, but worth mentioning, because hopefully they will try again. Long story short it was intended to monitor a whole slew of climate-related metrics to get us closer in touch with what the Earth is doing. Obviously very important work. This is actually the second satellite of this nature which failed to achieve orbit, so conspiracy theorists unite! (that’s the extent of my negativity here today)
Another neat thing I read about recently is the All-Sky Fireball Network. In addition to having a maximum ass-kicking name, the project monitors the sky with a nationwide network of smart cameras, with the aim of tracking any meteors burning up in the atmosphere. William Cooke, head of NASA’s Meteoroid Environment Office states coolly, “nothing will burn up in those skies without me knowing about it!” Sweet!!
Tracking these meteorites also gives them a vector for both where they should land and where they came from. Thus, if any of the meteorites leave remains that can be retrieved upon impact, the guys can study them, knowing a bit about their origin. Doublesweet. In effect it’s like getting free samples from outer space, without the need to launch costly rockets. Their data will also enable spacecraft designers to learn more about the nature of hole-punching threats that meteors would pose to future vehicles. Triplesweet.
Learning about something like that is exciting, but I also get the feeling like, geez, this is so great, why didn’t we start doing this like 30 years ago? Again, the technology is nothing new, it’s simply summoning the will to pay for it that holds us back. Every time something like this gets funded, our priorities inch a little closer toward making sense in my mind. It’s reassuring to think about!
