Now You Can Find Planets Around Other Stars at Home

I've always been a fan of ways that the general public (you and me) can help make discoveries and advance the state of science and technology. In the past, I've given updates on the PlanetQuest project, which seeks to give the general public the tools to help find extrasolar planets. That project is still in the works, but now the fine folks at Zooniverse (creators of the GalaxyZoo project, among others) have beaten them to the punch.

Zooniverse's latest citizen-science project is Planet Hunters, which displays the light-curve of a star on the screen and allows you to use one of the great strengths of the human brain&emdash;pattern recognition&emdash;to determine whether there are gaps or transit events in the light curve.

The site is pretty cool, but it has some problems... the biggest of which is no support for Internet Explorer. Your feelings on the various web browsers aside, a citizen science project should support the browsers most commonly used by the citizenry. Also, after you classify a star, it offers you the opportunity to discuss the star. But after you answer that question, the site has a tendency to hang. I spent some time classifying stars, and suffered a number of hangs.

Still, it is an interesting way to spend a little bit of time, and could result in discoveries of planets in the Kepler data.

$10 Billion to Save 8.7 Million Lives

I like helping people. That's why I belong to a volunteer service club within my community. I also give my money to worthy organizations every year. So imagine what I could do if I had billions of dollars!

Last week, the Bill and Melinda Gates Foundation announced that they would be committing $10 billion to provide vaccines against a wide range of diseases. That is an incredible amount of money, and could greatly reduce the occurrence of many preventable diseases, possibly saving an estimated 8.7 million lives—7.6 million of them children under the age of 5. Not to mention the number of people whose lives would simply be better.

According to the Chronicle of Philanthropy—which covers non-profit organizations—this is the largest single amount ever committed for a specific cause. It's also an incredible gesture, and I applaud Bill and Melinda Gates for taking this step.

NASA Wants Your Input

NASA has implemented an online brainstorming tool, open to the general public, seeking to improve openness, transparency, participation, and collaboration. Here is your chance to participate in developing the future of America's space program.

As you may know, I'm a big fan of openness and transparency. I'm also a fan of collaboration in science and government. In the United States, we live in a participative democracy, meaning that citizens are encouraged to get involved in government, from writing your Congressman to serving in the military to running for office. NASA's implementation of a system like this will encourage participation in government, which is a good thing.

The brainstorming system that they are using, by IdeaScale, allows for ideas to be submitted and voted upon by registered users, as well as allowing comments (like a blog) for the purpose of opening discussions. And if you have an account with Google, Yahoo!, WordPress, or AOL, you can log in by authenticating against that account.

So what are you waiting for? Go to the site and tell NASA what they need to be doing!

The New (Improved?) NASA

NOTE: Cross-posted to Getting There From Here.

If you follow space-related news, then by now you are surely aware that the White House released President Obama's budget plan for 2011-2015 today, and there is no funding for the Constellation Program (the Vision for Space Exploration created under Bush in 2003). So what does that mean? Everybody has their own opinion, but here's mine:

First, it means that the more than $8 billion spent over the past 5-6 years is basically wasted money (along with an additional $2.5 billion that will be spent to close down the program). A lot of people thought that Constellation was a flawed program—including me—but that's a lot of money to flush down the toilet. Sure, not all of it was wasted money. For example, we produced a few new scientific and technical innovations out of that money, but spending $8-9 billion to get what little we got (a single demo flight with non-representational hardware) was a bit crazy. And if Constellation had continued the way it was going, it would have been massively over-budget and late on delivering on its goals. Still, that means that the government will have spent more than $3,500 for each man, woman, and child in this country on a program that effectively accomplished very little.

At the same time, a new generation of rocket scientists got some first-hand experience at designing and building new (or at least updated versions of old) rocketry systems. Again, a pretty expensive price to pay to get some people some good experience, but given that the average age of our rocket scientists has been climbing since the 1960s, that's not really a bad thing.

But that's what it means for the past. What does it mean for the future? Well, that's pretty tough to say, since predicting the future is always a challenge. But here is what is being proposed: NASA will abandon low-earth orbit (LEO) to companies like SpaceX, encouraging and financially supporting a commercial space industry. Instead, NASA will focus on the heavy lift programs necessary to get us to the Moon, Mars, and asteroids.

NASA will spend $7.8 billion between 2011 and 2015 on advanced technology demonstration programs to explore more advanced exploration options. This includes in-orbit propellant transfer, closed-loop life support, automated maneuvering and docking systems, and inflatable space modules (similar to the ones that Bigelow Aerospace is experimenting with... perhaps the new focus on partnerships will allow NASA and Bigelow to work together on these). All of these technologies will be essential to exploring our solar system and beyond.

In addition, NASA will spend $3.1 billion on research into new propulsion systems (hopefully solar sails and VASIMR will be included in this spending) and another $3 billion on robotic missions to pave the way for human exploration.

All of this means that—with the Space Shuttle fleet retiring later this year—NASA does not have any way to get crew into orbit other than to pay $51 million per flight to the Russian Space Agency for launches aboard Soyuz capsules. To alleviate this, NASA is encouraging commercial spaceflight companies to pick up the slack by allocating $5.8 billion for crew launches provided by commercial operators. With the money already allocated to SpaceX and Orbital as part of the COTS program, they have an advantage over other small operators. But with that much money on the line, you can bet that Boeing, Lockheed Martin, and others (including, perhaps, the joint venture United Space Alliance, which operates the Space Shuttle program) will jump into the fray with commercial offerings.

And with the cancellation of Constellation and the end of the massively-expensive Space Shuttle program, more money will be available for basic scientific reasearch in the areas of Earth Observation and Astrophysics. Most interesting to me are added funding to get Mars Science Laboratory launched in 2011 and a probably 2014 launch for the James Webb Space Telescope.

I personally like NASA's renewed focus on research and development, while letting business enterprises commercialize the results on behalf of the government. Too much of NASA's budget over the past two decades has been spent on the Space Shuttle and International Space Station programs. While those programs have provided benefits (notably in the areas of living and working in orbit, including orbital construction methods), the costs once again far outweighed the benefits. The new plan will hopefully shake a lot of complacency out of the system and encourage creative thinking and innovation, while also spurring commercial development of space travel and exploration.

LHC Back Online

Scientists at CERN turned the Large Hadron Collider back on and injected protons into the particle stream on Friday, resuming operations for the first time in a year.

Last year, shortly after it became operational for the first time, the LHC experienced a failure in one of the containment magnets that keeps the particles within their track and going around in circles. Because of the tremendous forces required, these magnets are extremely powerful, and if they become misaligned by even a tiny amount, they can fail catastrophically, destroying themselves.

That's what happened last year, and resulted in repairs and replacement of the magnet. It took a while to complete the repairs because the LHC is kept at a brisk -271°C and had to be warmed up slowly, repaired, and cooled back down slowly, but the work is finally done and science is once again underway at the world's most powerful particle collider.

And, in case you hadn't noticed, it still hasn't destroyed the world.

Be a Martian

Regular readers of this blog (if there are any) know that I'm a big fan of things that people like you and me can do to help advance science and technology. Well, now thanks to Microsoft and NASA, there's another opportunity, and this one is very cool.

Microsoft and NASA have teamed together to create Be a Martian, a new website where you can help contribute to our understanding of Mars. By participating in the site—which largely consists of combing through the vast quantity of Mars images and classifying them, as well as participating in surveys and discussions—you can earn badges and "Reputation Points". But more importantly, you can help our understanding of our red neighbor... the knowledge you help provide may give some indication of where to look for microbial life, past or present. It may help find suitable locations for manned missions or even long-term colonies.

I haven't had a chance to do much other than view a few videos so far, but it looks very interesting, and I've bookmarked it so I can return this weekend and spend some time contributing to the future of science and technology.

Masten Space Qualifies for Lunar Lander Challenge X-Prize

NOTE: Cross-posted to the Blog at Getting There From Here.

Congratulations to Masten Space Systems on successfully completing their qualifying flight for the $1 million prize in the Northrop Grumman Lunar Lander Challenge X-Prize. They join Armadillo Aerospace in qualifying for this prize.

To qualify, both companies had to demonstrate control of their vehicle by flying to an altitude of more than 50 meters, flying laterally for 100 meters, and landing on a simulated lunar surface complete with craters and boulders. After doing so, they vehicle had to take off from the simulated lunar surface and return to its starting point (with the option of refueling the vehicle between flights). And, oh yeah, they had to complete all of this (including any necessary refueling) in less than two-and-a-half hours.

Another team, Unreasonable Rocket, will attempt to complete their qualification tomorrow. BonNovA had intended to compete but had to withdraw.

We at Getting There From Here are huge fans of these types of competitions, as they allow a small amount of money to go a long, long way. In this case, the $2 million total prize money for the Lunar Lander Challenge has generated more than $20 million in research on rockets and helped at least a couple of small, entrepreneurial rocket companies to literally get off the ground. Kudos to the X Prize Foundation and Northrop Grumman for organizing and funding such a great contest.
