promo9

There’s six hours of new space news and opinion waiting for you in the Astroengine Live archives! You can listen in to shows 13, 14 and 15 via the Black Vault Radio Network widget on the Astroengine Live page on Astroengine.com, or you can download them via iTunes for some iPod goodness. Any problems listening in, please let me know.

Synopsis of each show and the dates they aired:

11th March, 2009 – Astroengine Live #13: I discuss some of the most interesting space news topics from the last two weeks. Included in the March 11th show:

Searching for exoplanets with the recently launched Kepler space telescope.
Religious dogma vs. 2012 doomsday theories.
When does virtual reality become physical reality? Does it even matter?
General news from Astroengine.com
The Carnival of Space and 365 Days of Astronomy (featuring the March 3rd podcast by Dave Mosher)
And a whole new playlist of music for your listening pleasure.

There’s a lot more besides, as the previous week’s Astroengine Live didn’t happen, so the “lucky” 13th show went ahead with double the dose of space news.

25th March, 2009 – Astroengine Live Show #14 (Bats ‘n’ Books): A run-down of the week in space, plus a special announcement of the upcoming book: “Astroeconomics: Making Money From The Vacuum Of Space” (a joint venture between BusinessWeek.com and WorldofWeirdThings.com blogger Greg Fish and Astroengine Live host Ian O’Neill). Also, I examine all the fuss about the free-tailed bat that died during the March 15th shuttle launch and plans to honour the endeavours of animals in space.

1st April, 2009 – Astroengine Live Show #15 (Carnival of Space Live!): In a very special edition of Astroengine Live and the Carnival of Space, I host the Carnival on Astroengine.com and gave it the run-down on Astroengine Live! A live Carnival has never been done, so if you want a show with over 30 space science topics squeezed into 120 minutes, this is the show for you!

Listen to Brian Cox on BBC Radio 4: A Tribute to Carl Sagan (Update)

Listen to Brian Cox’s Tribute to Carl Sagan – it is fantastic »

News just in from Gia Milinovich via Twitter:

Physicist and broadcaster Brian Cox presents a tribute to his science hero, the American astronomer Carl Sagan, the man who many people describe as the greatest populariser of science of all time. His landmark television series Cosmos was seen by more than 600 million people worldwide and inspired a generation of young scientists to regard the universe with wonder and awe. — Synopsis about Brian’s show on BBC Radio 4

I’m a huge fan of Brian’s work, he’s a fantastic and entertaining communicator of all things scientific, so this is the perfect tribute to legendary astronomer and presenter, Carl Sagan. I’ll be sure to tune in… with my late-morning coffee. According to Gia, Brian thinks this is the best show he’s done, so if that’s anything to go by, this is one event you cannot miss!

Catch the BBC Radio 4 stream at 8pm GMT (in the US, that’s midday PST or 3pm EST).

“Moon” Movie Trailer Now Online

Why didn’t I know about this movie?

I have no clue how I didn’t notice this film was in the works, but it would appear I’m not quite as well plugged into the sci-fi pulse as I used to be. Announced last year, “Moon” is set on the lunar surface where a lone contractor is manning the Helium-3 mining operation. Acted by Sam Rockwell, the setting looks like a visual treat, bound to get any science fiction enthusiast’s taste buds excited. However, yesterday the trailer was released ahead of its June 12th release… and it looks good…

Astroengine Data Gathering

Astroengine needs a new look

Every few months, I think it’s healthy to reassess the design of Astroengine and develop it where necessary. In response to recent user feedback, I’m finding that the biggest weak spots of the site are firstly its speed and secondly its cross-browser compatibility.

Unfortunately visitors to the site that run Internet Explorer 6 see a mashed-up, messed-up Astroengine. It turns out that many of IE6 users are not using this out-of-date browser out of choice, it appears to be the staple of office computers the world over (system administrators really should think about updating their software once and a while).

In fact, I even had the chance to see Astroengine through IE6’s eyes a week ago, and I felt a little light-headed – It. Was. Nasty! Although I will always test sites that I build with a variety of browsers, I can’t test my site on old browsers (and therein lies the problem). The number of IE6 users are quite small, the numbers are significant according to my stats, so I’ve decided to act…

40% More Solar Energy For Opportunity

Good news for Mars Exploration Rover Opportunity, a windy day on the Martian surface has cleared a layer of dust off its solar panels.

Opportunity is currently trundling across the undulating dunes of Meridiani Planum on its way to Endeavour crater, a destination it wont reach for another two years. It needs all the energy it can muster. So, like the fortuitous gust of wind that gave Spirit a 3% boost in energy in February, Opportunity has received what may appear to be a small hurricane in comparison. This gust of wind shifted so much dust caked on the rover’s solar panels, the robot has had an energy increase of 40%.

As of Sol 1850 (April 7, 2009), Opportunity’s solar array energy production has increased to 515 watt-hours. Atmospheric opacity (tau) remains elevated at around 0.95. The dust factor has improved to 0.642, meaning that 64.2 percent of sunlight hitting the solar array penetrates the layer of accumulated dust on the array. The rover is in good health with a rested actuator and extra energy. — NASA Opportunity updates

Since Opportunity arrived on Mars five years ago until April 7th, the tenacious rover has travelled 15,114 meters (9.39 miles). For a mission that was only slated to last three months, that’s not a bad distance its clocked up.

Getting to the Moon More Expensive than Bailing Out AIG?

I’m sure it’s more expensive than bailing me out of my student loan too…

The top stage of the Ares V carries the Altair Lunar Lander on its way to the Moon (NASA)

In an article written by a columnist in the Orlando Sentinel, NASA’s Constellation Program is compared with the government bail out of AIG. Where’s the correlation? No, I don’t see it either. NASA has its problems (some of the problems are very big problems), but when you begin comparing the woes of a space agency with an ailing financial corporation, you’re not only off target, you’re not quite understanding the true value of space exploration…

Naming Pluto: The Trailer

I can’t emphasise enough how much I love this short film. It may only be 13 minutes long, but it is as small as it is mighty, much like the dwarf planet itself.

“Naming Pluto” documents the adventure of how Pluto got its name. Inevitably with most astronomical studies, there can be some controversy surrounding the naming of celestial objects, often depending on traditional naming protocol and who made the discovery first. The naming of Pluto on the other hand appears to take on a more natural tact, starting with a conversation in 1930 involving a little girl named Venetia Phair and her grandfather, over breakfast in Oxfordshire.

Father Films have just released a trailer for their magnificent film, giving you a taster as to what to expect. I had the pleasure of watching and reviewing a copy late last year, and I was blown away by the accuracy, wonder and history that can be packed into 13 minutes (note that the DVD has extras included, extending the content to 40 minutes). I fell in love with Pluto all over again – suddenly the fact that the IAU had demoted the planet to a dwarf planet (and then to a plutoid) didn’t matter any more. Written, directed and produced by Ginita Jimenez, Naming Pluto is in the true spirit of the International Year of Astronomy, capturing the excitement surrounding a tiny member of the Solar System with excellence. I wholeheartedly recommend this short film, it needs to be in your DVD collection! Patrick Moore is also at his best, giving the proceeds his unique style. And don’t just take it from me, Astronomy Now has also given the film a highly enthusiastic review.

You can purchase a copy of the DVD and poster from the Father Films website.

C.A.T. Scans of the Solar Wind

Guest article by Dr. Mario M. Bisi (Research Focus)

A cut in the ecliptic plane through a 3D reconstruction on 08 November 2004 at 0000 UT using white-light data from SMEI. The view is from directly North of the ecliptic; the Sun is at the centre marked by a +, the Earth is on the right marked with a ⊕ along with its orbit as a black near-circular line around the Sun (the Earth orbits anti-clockwise around the Sun from this point of view). The darker the colour, the greater the density of material in the ecliptic. (©Dr. Mario M. Bisi)

The Computer Assisted Tomography (C.A.T.) technique has been used for many years now and is well known for use on people where certain health conditions need more thorough, detailed, and deeper scans into the human body and the need for three-dimensional (3D) reconstructed imaging. However, similar such scans can also be used on the solar wind to discover the shapes and sizes of structures near Earth and throughout the inner heliosphere in three dimensions. These scans have been carried out for some time, pioneered in the most part by those at the Center for Astrophysics and Space Sciences (CASS), University of California, San Diego (UCSD) in La Jolla, CA, U.S.A. in close-collaboration with the Solar-Terrestrial Environment Laboratory (STELab), Nagoya University, Toyokawa, Japan…

NASA’s Continuing Foray Into Pop Culture

Guest article by Greg Fish (blog: world of weird things)

zz_colbert

Oh what havoc faux-conservative pundit Stephen Colbert wrought on NASA and the ISS! To think that a little publicity stunt would actually put the U.S. space agency in a jam and incite grudging grumbles from Firefly fans who were sure that Node 3 would be called Serenity. Even a few Congressmen who found time away from dealing with a painful and deep recession that’s put the entire economy in turmoil, are now involved in sorting out this little mess.

But there’s actually an interesting question in this seeming non-story. Should NASA embrace the will of the masses and give nods to pop culture in how it officially names its spacecraft? There are stories of informal call signs for capsules and modules taken from the Peanuts comic strip, but there’s never been an official designation that reflects what’s popular here on Earth at the time of the mission. What would benefit NASA more? Giving in to the power of the fad or staying resolute with timeless names?

WR 104: Not The Killer It Used To Be

It’s interesting how astronomical harbingers of doom have the ability to pop up more than once on the ‘net. However, the doom isn’t quite as terrifying when you’ve sat through a conference presentation by a scientist who has exhaustively given every reason as to why this particular killer won’t hurt you.

Enter WR 104.

To be honest, if it wasn’t a Wolf-Rayet star, I probably wouldn’t be writing about it (as we all know, or you should know, Wolf-Rayets are my favourite stellar objects), but this little fact combined with the fact that I know the Earth is no longer on the WR 104 hit-list, I feel compelled to correct an article that has just popped up on the web referencing out-of-date source material.

So, let’s wind this back the clock to January 2009 when I sat in on a very reassuring this-star-isn’t-actually-going-to-kill-us-after-all astro presentation…
