Interview: Ken Mogul on using Global Rent-a-Scope

Doug interviews Ken Mogul, who has been using the Global Rent-a-Scope system to observe variable stars from his bed. Doug and I also discuss some random topics including some interesting papers on astro-ph.

Here’s some links from the interview:

A new post-Slacker blog

Hey. This is non-astro related so apologies for putting noise in your signal. I’ve started a new blog called:

Two Eyes, 3D

It’s about stereoscopic vision and technology, what most people associated with “3D glasses”. It’s the center of my research interest in grad school. So if you are into that sort of stuff, check it out.

I guess it will have something to do with astronomy. My first stereoscopic research was done at the Adler Planetarium (hopefully to be published soon so you can read it) and my next research will likely involve galaxy simulations. I’ll describe it all in detail at the other blog. And I hope to write more for Slacker also. I’m done with classes in grad school now!

Good news for rocketeers

The Office of Commercial Space Transportation, a division of the Federal Aviation Administration, has issued new regulations for amateur rocketry. The paper, Requirements for Amateur Rocket Activities Final Rule, December 4, 2008, is a bit long and dry but, from what I can tell, simplifies life for most amateur rocketeers.

In summary:

Maximum Altitude Definition of 150 kilometers or 492,120 feet. This is in place of old rules about the maximum burn time below.
Suborbital Requirement. You can’t go into orbit without upping the amount of papework!
Not Cross International Boundary. Related to the above, you can’t cross borders with your rockets.
Elimination of Burn Time and Ballistic Coefficient Requirements. You don’t have to compute the density of your rocket or limit it by burn time.
Revision of Amateur Rocket Classes. There are now 4 classes of rockets, “Model”, “High-Power Rockets, “Advanced High-Power Rockets” and “Other”. The model rocket category no longer requires any notification to the FAA for launches. The maximum weight of a model rocket has gone from 16 oz. to 53 oz. and the maximum propellent from 4 oz. to 4.4 oz.

Here is a screenshot of the new classes of rockets:

All in all it looks like pretty good news for amateur rocketeers, especially those flying smaller rockets.

The article at The New Scientist makes a good point for commercial rocket programs as well:

The main importance of this for the entrepreneurial space community is the removal of the burn-time limit. With that change, many small rocket vehicles qualify as amateur rockets, at least for early development testing.

Now if we could only get the ATF to lighten up on the hobby.

Props where props are due

Hey, all. Long time listener… first time caller (so it seems)…

As listeners know, I like to critique poor astronomy press releases. Part of the problem stems from writers who base entire articles on those press releases, with doing no vetting on their own. Can you imagine if political writers did that? They do? Okay, you’re making it hard to make my point, so I’ll distract you with shiny things and dangling string and get back to the topic at hand…

I want to throw a shout out to Clara Moskowitz at Wired.com for this article. It is a very simple article about naked eye astronomy this week. I find it a practically perfect astronomy piece. It doesn’t hype it but it still puts the event in perspective. It’s clear, correct and to-the-point. This conjunction was especially beautiful and I know many non-astro friends who commented on it to me. It was so well placed that the public was interested. Look at the comments she got on that post: 81 vs. the comments she got on her most recent post before that: 10. A story like hers will be a great gateway for the general public to learn a bit more – and perhaps come back later for more.

I only took points off for the obligatory Star of Bethlehem reference that every astronomy news outlet trots out every twelve months. But I can hardly fault her for getting into the Christmas spirit.

I haven’t read her stories before, so I’ve bookmarked her column and look forward to more. I checked out a couple of her most recent and they seem similarly clear, with some light humor thrown into each piece. She seems especially handy at headline writing.

Kudos to Clara. Wired, take care of her!
