Opportunity has been packed for its journey to the launch site in Florida. Here are the four days of work, compressed into a 1-minute time-lapse video:

While spending a day at the Jet Propulsion Laboratory last week, I had a chance to say “good-bye” to NASA’s upcoming Mars rover, Curiosity (aka Mars Science Laboratory). Next week, the rover and its descent platform will be crated and driven by truck to a nearby March Air Reserve Base. From there, it will travel by cargo plane to Cape Canaveral in Florida for launch.
In this image, the spacecraft is undergoing final checks. (The rover can be seen on the left. Nearby on the right is its unique “Sky Crane”, a rocket propelled, floating landing platform from which the rover will rappel down to the surface of Mars).

Here is JPL’s control room. From here, communication with all of JPL’s unmanned spacecraft is maintained around the clock.

I am very excited about this mission and hope everything goes well. It is very complex for sure. Here is a simulation of how it is supposed to work:

NASA has invited me to spend the entire day of Monday, June 6 at the Jet Propulsion Laboratory (NASA’s center for unmanned spaceflight).
All day long, I will be visiting the facilities where NASA’s unmanned spacecraft are designed, built and controlled. I will be chatting with engineers and scientists about upcoming missions and advances. Among other spacecraft, I will see the upcoming Mars Rover “Curiosity”, saying final good-byes before it is sent to Cape Canaveral for launch.
Throughout the day, I will be reporting live via Twitter (and other social media). Please follow my feed!

Twitter is a new medium which now has over 200 million users. Twitter messages (called “Tweets”) are brief messages of 140 characters or less. (This means they can be received on cellphones — but also on the worldwide web).
Although they are brief, “Tweets” may contain links to photographs, videos, articles, online posts or other material of interest.
You do not need a Twitter account to read the messages on your computer. But it would be helpful if you have one. (It does not cost anything). Having a Twitter account enables you to selectively and automatically follow updates from individuals, institutes and organizations, and it also allows you to “talk back”.
Hoping to see you in cyberspace!

This was driving me crazy: I once took a series of photographs of Maria Altmann, the heiress of several Gustav Klimt paintings. (She successfully sued the Republic of Austria for the return of famous art worth $328 million, and passed away earlier this year. See my other blog post on Maria Altmann).
But the pictures I had taken went missing. As I was going through old boxes yesterday, the set re-emerged. (It turns out I had just tossed them into a box, along with all kinds of other “stuff”, instead of filing them away). Here is what I think is the best image from the series:

Yesterday was the 100th anniversary of the Indy 500 auto race. I followed it on TV and was astounded by the many mishaps in the pits. They were all caused by the driver taking off before the crewmen had completed their tasks. This is how races are lost. Sometimes, lives are put in jeopardy as wheels and other parts turn into projectiles, or racing fuel catches fire.
One question bugs me: why is there no “lollipop man” — like in Formula 1? This is a crew member whose sole job consists of monitoring the pit crew to make sure everyone is done. While they work, he holds a “stop” (or “brake”) sign on a long stick (the “lollipop”) in front of the driver’s eyes. Once all crew members signal “clear”, the lollipop man turns the “stop” sign to “go” and jumps out of the way as the driver guns the engine.
This would be a simple solution to an old problem. I can’t figure out why Indy 500 teams are not employing it. Overall, it seems to me that pit stops in Indy racing are by far not as sophisticated compared to what happens in Formula 1.

Somehow it seems that these guys were having more fun than their counterparts from today. I love the ties! (Seriously — I collect vintage ties from the 1930s to the 1950s).

I have been interested in ethanol as a motor fuel for years. I came to the conclusion that much of the myth about the so-called inefficiency of ethanol as a motor fuel has been planted by the oil industry.
Technically, ethanol makes an excellent fuel — one that is superior to gasoline in many ways. Is it far less toxic, less explosive and less volatile than gasoline. It does not form sticky goo when stored for a long time. When spilled, it can simply be flushed away with water. If spilled into waterways or ground water, it will easily disperse. It is biodegradable. Ethanol does not require toxic additives to prevent “gunking”, or to increase the fuel’s octane rating (a measure for the fuel’s resistance to premature detonation).
Engines specifically designed to burn ethanol can achieve much higher compression ratios than gasoline engines. This can minimize one disadvantage of ethanol: its energetic density is less than that of gasoline, which means that an engine will burn more ethanol to achieve the same power output of a gasoline engine. However, an engine designed to burn ethanol runs a lot cleaner and cooler than a gasoline engine with the same power output.
Unfortunately, the inefficient way by which ethanol is handled in the U.S. is just plain stupid. It is the result of foul politics and lobbyism. Today, almost all ethanol is made from corn. It is true: this is not efficient. But it does not have to be that way.
Instead, three things should happen:

Atomic trains! Space patrol cars! Robots, space tanks and of course — the “Luna Hovercraft”! I love this stuff. See Life Magazine’s gallery:

50 years ago this month, Alan Shepard became the first American to fly into space.
Although the intensely celebrated accomplishment was technically much less challenging than that of Yuri Gagarin’s earlier flight, it was the event for which America had been waiting. (Gagarin’s flight orbited the Earth, while Shepard’s capsule stayed only on a 15-minute, ballistic trajectory).
Shepard, a U.S. Navy aviator and test pilot, was one of America’s original 7 “Space Heores”. Besides Project Mercury, Shepard also flew on Gemini, and later in 1969, he commanded Apollo 14 and landed on the moon.
Shepard died from leukemia in 1998, in Pebble Beach, California.
