When starting to create the movie, Gray said “Ad Astra” would be a “science feature fact” film and that he would endeavour to make it the most realistic space movie yet created. He admitted he had to adjust that vision as production continued. “A lot of times when you start working on a project, you start to say unbelieveably dumb things,” he joked.


Brad Pitt says his new space movie “Ad Astra” won’t have a clear position on whether humanity is alone in the universe.

Bioweapons have been around for centuries, but with advances in synthetic biology we’re now able to make them from scratch.

The man who stopped America’s biological weapons program

“Today, the use of biological weapons is almost unthinkable. But this wasn’t true in the 1960s, when the US government stockpiled such weapons and work continued on developing new, more effective variants. There was an agreement about the use of biological weapons — the post-World War I Geneva Protocol, which also covered chemical weapons — but the United States wasn’t among the signatories to it.”

Synthetic biology raises risk of new bioweapons, US report warns

“The rapid rise of synthetic biology, a futuristic field of science that seeks to master the machinery of life, has raised the risk of a new generation of bioweapons, according a major US report into the state of the art.”

INTRODUCTION

Throughout the ages, pioneers have been questioning the accepted belief systems of the populace, and producing major evolutionary leaps: “The Earth is the centre of the Universe” gave way to the understanding that the earth revolves around the sun. “The Earth is flat” fell away when Columbus did not fall over the edge. The Wright Brothers also flew us into another reality as have countless others. I will be suggesting in the words to follow that the belief system “physical death is inevitable” may have a similar fate.

The current menu of space-friendly foods uses processing and water-reduction strategies to make these meals shelf stable. For example, a shrimp cocktail, mashed potatoes, and strawberries can be freeze dried; beef stew, candied yams, and brown rice can be thermostabilized; beef steak and turkey can be irradiated; and brownies, bread products, and beverage powders can be brought up in a low-moisture or dried form.

As tasty as this feast sounds, this packaged food system does not meet the five-year shelf life required for a Mars mission, nor will it feed generations there in the years to come. How will space food therefore have to change if we are ever to colonize other planets?

Using existing space technologies, it will take up to 32 months to travel to Mars. How can you feed a crew for that three-year trip?

The tradition of road rage on earth does not apply to space where someone can yell at you to move. There has to be a channel of communication form the earth’s control centres and even then, those emails can be missed. Well, this may have almost caused two assets to run into each other about 350 km above Earth last weekend. This involved a Starlink satellite belonging to SpaceX and the European Space Agency’s Aeolus satellite.

The incident actually started on Wednesday when the US Air Force’s 18th Space Control Squadron issued a risk warning to both organisations. The unit that monitors space vessels and debris warned that the collision might happen around September 2nd at 7 am ET, with a 0.1% probability.

Another of those ‘new eras’ I talked about in yesterday’s post is involved in the latest news on gravitational waves. Let’s not forget that it was 50 years ago — on November 28, 1967 — that Jocelyn Bell Burnell and Antony Hewish observed the first pulsar, now known to be a neutron star. It made the news at the time because the pulses, separated by 1.33 seconds, raised a SETI possibility, leading to the playful designation LGM-1 (‘little green men’) for the discovery.

We’ve learned a lot about pulsars emitting beams at various wavelengths since then and the SETI connection is gone, but before I leave the past, it’s also worth recognizing that our old friend Fritz Zwicky, working with Walter Baade, first proposed the existence of neutron stars in 1934. The scientists believed that a dense star made of neutrons could result from a supernova explosion, and here we might think of the Crab pulsar at the center of the Crab Nebula, an object whose description fits the pioneering work of Zwicky and Baade, and also tracks the work of Franco Pacini, who posited that a rotating neutron star in a magnetic field would emit radiation. Likewise a pioneer, Pacini suggested this before pulsars had been discovered.

Writing about all this takes me back to reading Larry Niven’s story ‘Neutron Star,’ available in the collection by the same name, when it first ran in a 1966 issue of IF. Those were interesting days for IF, but I better cut that further digression off at the source — more about the magazine in a future post. ‘Neutron Star’ is the story where Beowulf Shaeffer, a familiar character in Larry’s Known Space stories, first appears. If you want to see a neutron star up close and learn what its tidal forces can do, you can’t beat Niven’s tale.
