Fri May 21 23:30:08 2010 Space Plan Now I have even more respect for the new NASA direction. |
The Constellation program: beautiful! But not smart.Image courtesy of Cassini83 (wiki) A friend of mine is the Astronomy columnist for the
Seattle Examiner. If you are interested in Astronomy in the Seattle area, you should definitely read
his articles!
He recently posted an article about former NASA administrator
Michael Griffin's talk at the Boeing Museum of Flight, in which Griffin wasn't entirely supportive of the new NASA direction. In
particular,
|
Michael Griffin takes strong exception to most of President Obama's proposed space exploration policy, disagreeing with the major points and calling much of it "drivel." |
Harsh! Griffin called the new direction "Obama's proposals", although most of them came from
the so-called Augustine Report, the outcome of the Review of US Human Spaceflight
Plans Committee.
You can find the Augustine Report
here, which is very readable! If you are at all interested in the US space program
I recommend flipping through it. It is over 150 pages (ack) but I read through
the Introduction (Chapter 1), the coverage of current programs (Chapter 4), and
their evaluation of critical technologies (Chapter 7).
It is a pretty interesting report!
Popular Mechanics has an online article about
5 Surprising Passages from the Full Augustine Report.
[If you flip through the report, on page 12 you'll find an awesome diagram showing the
International Space Station, color-coded by which country supplied the
components. It is clear that the ISS is almost exclusively a US and Russian
venture, although Japan kicked ass (far above the European contributions).
Although, before I deride Europe too much, I should given them the benefit of
the doubt--they may have recognized early on that the ISS was a colossal waste
of money.]
Orion docked at the ISS -- that's a lot of cash!Image courtesy of GDK (wiki) Michael Griffin also didn't like the Augustine Report "which he feels got some
things right but blew many others."
Many astronauts also don't like the new direction. Neil Armstrong and Eugene
Cernan, the first and last astronauts on the moon,
testified to the Senate that
|
...this budget proposal presents no challenges, has no focus, and in fact is a blueprint for a mission to nowhere. |
Ouch! However, not all astronauts agree with them. For instance,
Russell Schweickart recently wrote that the new direction was a much-needed change. Schweickart noted
|
Our current situation is akin to being on a dead end road... [the Obama plan] recognizes and eliminates the waste of precious resources in the current program and heads us in a productive direction toward our desired destination. In other words, when you recognize you are on a dead end road, stop, turn around, and head in a direction more useful to your goal. |
And of course, my own blog posts (
No Moon and
Moon Shot ) significantly elevated the national debate.
Recently
The Space Review ran a series on the new direction (see
part 1 and
part 2 ). The review is somewhat politically-heavy (for instance, worrying that a
more efficient NASA will mean less pork to keep congress happy) but basically
calls out the main differences of Obama's plan:
- We aren't building a big new crew module, but will rely on private
industry for many launches.
- We aren't landing on the moon again. Instead we'll land on an
asteroid.
- We are still heading for Mars as an end goal.
Orion in orbit around the moon -- why?Image courtesy of GDK (wiki) Obama's plan is good about separating the many phases of launching people and
material into orbit. For instance, both the Shuttle and the Constellation
programs have the same problem: they use the same vehicles for people and cargo.
This is very expensive, since any manned vehicle has huge overhead for safety!
Separating the two (launching people and cargo using different vehicles) is much
cheaper and may be more reliable--and safer.
Also, Obama's plan puts more funding into private space companies for launches
into low earth orbit. This wasn't a viable option ten or twenty years ago, but
it is now. And it means that we'll build out our private launch industries, let
them spread the risk and try out new technologies, and let NASA focus on other
issues such as deep-space propulsion and life support. Much better!
So I understand why many people aren't happy about he change in direction. And
certainly Michael Griffin is worried about his legacy. But the new NASA
direction looks better and better the more I look at it.

Fri May 7 22:44:43 2010 Tree-Hugger Me I'm a die-hard environmentalist in spite of my SUV. |
This environmentally-conscious SUV also has a snorkel.Image courtesy of Dazzuko (wiki) Today I celebrated 6 weeks of commuting to and from work without driving!
This is all because I recently moved (see
The Dream Tour), and I can bus to work and walk to almost everywhere I need to shop. I've been mostly commuting by
public transit since December, but in March my parking pass ran out so I've been commuting 100% car-free since
then. My gasoline consumption has dropped by around 50% or more compared to
2009, even though I
often drive into the mountains on the weekends.
However, I still drive a large black SUV that gets really crappy gas mileage.
So I can't really call myself an environmentalist, can I?
Well, actually I can and I do.
I was inspired by
this story, which pointed out that most people think about environmentally-friendly
driving entirely wrong. Most people think that we can help the environment by
buying cars with better gas mileage. But as the article noted:
|
Science shows that cutting miles traveled by personal automobile is far more effective at reducing carbon than improving gas mileage. |
So by moving and driving far less, I've actually reduced my carbon footprint
much more than had I stayed where I was and bought a Prius.
Don't get me wrong, eventually I'll get a greener car. But it won't be a Prius.
It will be an SUV that has cleaner emissions. I need a truck with clearance,
room for cargo and gear, and four wheel drive.
That's another thing many people (including proclaimed environmentalists) get wrong, by the way. When it comes to the
environment, gas mileage isn't
important: emissions are important. The two are related, but they don't have to
be. Car and truck manufacturers could be held to much stricter emissions
than they are now. Paradoxically, better catalytic converters could slightly
reduce gas mileage, but that would be overall worth it.
So what is the responsible, green future for the planet? It won't be suburbia
with
hybrids. It will be people living much closer to where they work and shop, driving far
less, in cars that have about the same gas mileage as now, but with lower
emissions. That's going to be a big demographic shift, but it will be better for the
atmosphere, and will also be forced by
rising gasoline prices.

Tue Apr 6 22:25:15 2010 Gene Patents A surprising verdict that could change everything. |
What with the
passage of the healthcare bill,
the recent strategic armaments treaty, and
earthquakes, an important story was mostly buried this week. The story, which is
causing an uproar among biologists, is that
the ACLU has just won a lawsuit which
invalidates several gene patents.
This article has a great overview of how the case unfolded.
This is big news. Why?
On the one hand, many people are worried that by blocking patents of human
genes, companies and institutes will be unwilling to investigate
genetically-targeted (or inspired) drugs. For instance, the
Northwestern University report quoted above includes a quote from one lawyer:
|
You won't have disclosure to move onto the next step in biology |
that is, because patents won't be filed, companies will keep genetic sequences
private.
However, that same article quotes other practicing scientists as saying
|
There could be an increase in the amount of research done to attempt to find cures for disease. |
and also notes independently that
|
Myriad Genetics could find other labs rivaling it and might be forced to lower the cost for the BRCA test. |
[Myriad Genetics was the defendant in the lawsuit, and their BRCA breast
cancer test relied in
part on patents on the human BRCA1 and BRCA2 genes.]
I'm with the scientists on this one. Allowing patents of standard human gene
sequences is dumb and contrary to the spirit of patents. It was a mistake to
have allowed it in the first place, and the ACLU was right to challenge it.
Is this the end of patents for biotech? No. Even the scientists who supported
the lawsuit noted that
|
The company spent significant time and money figuring out the structure of the gene and how to test for it, and thus are able to charge what they want to for the test. |
In short, companies can patent anything they invent that is original, but can't
patent Mother Nature.
It is early days still! The result will almost certainly be appealed. But I am
hoping that higher courts will uphold the verdict. If so, I think we'll see
even more genetic information publicly available, which should speed cures and
lower costs for everyone.
