Electric cars and their cold-weather shortcomings

Reality meets feel-good politics: Electric cars and their cold-weather shortcomings. Key quote:

“If you live in an area where the winters get extremely cold an all-electric vehicle will have to be garaged and equipped with some kind of plug-in battery warmer for it to be effective in the coldest months of the year. Keep these thoughts in mind if you’re planning an electric car purchase; we don’t want you finding out the range of your car has been halved when it’s five below zero and you’re fifteen miles from home.”

Challenger, 25 years later

Today is the 25th anniversary of the Challenger accident. There are innumerable links from many sources talking about the event, too many for me to list here. You can find most at this link on Jeff Foust’s website, spacetoday.net.

Though I think it is very important for us to remember and honor these events, I have become somewhat disenchanted with the modern American obsession with memorials and anniversaries. Rather than build a memorial, I’d much rather we focused entirely on building new spaceships, new space stations, and new lunar bases, while flying multi-year missions on ISS, all in preparation for exploring and colonizing the solar system.

If we actually made the solar system a place for humans to live in and explore, we would build a far better memorial to those who have sacrificed their lives for the sake of exploration. And I think these heroes would be far more pleased by that memorial than by a stone statue or emotional op-ed that describes their courage.

Japan’s IKAROS Solar Sail Mission Extended for a Year

More solar sail news: Japan’s solar sail mission, IKAROS, has been extended for a year. Key quote:

With the extended lease on life, the team will try new navigational tricks, such as varying the sail’s angle toward the sun and changing the craft’s trajectory. Mori called these “risky” maneuvers because they are not sure if the sail will remain fully extended. They intend to model the sail’s behavior and the craft’s response to plan future solar sail missions.

Climate change study had ‘significant error’: experts

Climate scientists admit that a climate change study which claimed the Earth would warm by more than 4 degrees Fahrenheit in about a decade had “significant errors”. Key quote:

Scientist Scott Mandia forwarded to AFP an email he said he sent to Hisas ahead of publication explaining why her figures did not add up, and noting that it would take “quite a few decades” to reach a warming level of 2.4 degrees Celsius. “Even if we assume the higher end of the current warming rate, we should only be 0.2C warmer by 2020 than today,” Mandia wrote. “To get to +2.4C the current trend would have to immediately increase almost ten-fold.”

The state of Virgin Galactic

The state of Virgin Galactic. Key quote:

One of the great things about Galactic is that it’s still built on a non-government market — that is to say, the individual spacefarer market, the space tourist market, call it what you will. As you know, we’re now over 400 people [who have paid deposits for a spaceflight], and over $55 million dollars in deposits. None of that is based on a government program. I think that’s really encouraging. It’s a sign that there are markets outside the government, and that you can build a human spaceflight business around those markets.
