New NASA-themed TV Pilot by ‘The Martian’ Author Andy Weir

Author Andy Weir, who wrote the bestselling novel “The Martian” on which the successful 2015 movie of the same name was based, announced CBS is picking up his idea for a new pilot for a television show called “Mission Control.”

“For the past several months, I’ve been working on a TV show pilot, and I’m happy to announce that CBS is going to make it!” Weir posted on Facebook. “Of course, I’m all about scientific accuracy and this show will be no exception.”

Weir added (in what I assume was his best Tom Hanks), “Should be a hell of a show.”

The show will be a drama, with the main characters working as flight controllers at the Mission Control Center in Houston, and how they “juggle their personal and professional lives during a critical mission with no margin for error,” reported Deadline Hollywood.

Weir said casting for the actors is about to begin, but there is already “an impressive group of behind-the-camera people already involved,” he said. “Notably: [producer] Aditya Sood, whom I worked with before on “The Martian”.

Additionally, Simon Kinberg, another producer for the “The Martian,” will be the executive producer of the new series.

Andy Weir on Universe Today’s “Weekly Space Hangout” in January 2015:

Weir was first hired as a programmer for a national laboratory at age fifteen then worked as a software engineer. But as a lifelong space nerd and a devoted hobbyist of subjects like relativistic physics, orbital mechanics, and the history of manned spaceflight, he wrote “The Martian” in his spare time. Weir originally self-published the novel in 2011, but it was so successful, the rights to it were purchased by Crown Publishing and it was re-released it in 2014. A film adaptation directed by Ridley Scott and starring Matt Damon, was released in October 2015.

“The Martian” is the story of astronaut Mark Watney, who becomes stranded alone on Mars in the year 2035, and does everything he can to survive.

Weir didn’t provide a timeline of when the show would air, but Keith Cowing at NASAWatch reported that NASA Public Affairs “has been approached by the show’s producers and they are waiting on a script for final consideration. At this point NASA has not committed to assist the producers, allow use of its logo, facilities, staff etc.”

What is the Mars Curse?

What is the Mars Curse?


Last week, ESA’s Schiaparelli lander smashed onto the surface of Mars. Apparently its descent thrusters shut off early, and instead of gently landing on the surface, it hit hard, going 300 km/h, creating a 15-meter crater on the surface of Mars.

Fortunately, the orbiter part of ExoMars mission made it safely to Mars, and will now start gathering data about the presence of methane in the Martian atmosphere. If everything goes well, this might give us compelling evidence there’s active life on Mars, right now.

It’s a shame that the lander portion of the mission crashed on the surface of Mars, but it’s certainly not surprising. In fact, so many spacecraft have gone to the galactic graveyard trying to reach Mars that normally rational scientists turn downright superstitious about the place. They call it the Mars Curse, or the Great Galactic Ghoul.

Mars eats spacecraft for breakfast. It’s not picky. It’ll eat orbiters, landers, even gentle and harmless flybys. Sometimes it kills them before they’ve even left Earth orbit.

At the time I’m writing this article in late October, 2016, Earthlings have sent a total of 55 robotic missions to Mars. Did you realize we’ve tried to hurl that much computing metal towards the Red Planet? 11 flybys, 23 orbiters, 15 landers and 6 rovers.

How’s our average? Terrible. Of all these spacecraft, only 53% have arrived safe and sound at Mars, to carry out their scientific mission. Half of all missions have failed.

Let me give you a bunch of examples.

In the early 1960s, the Soviets tried to capture the space exploration high ground to send missions to Mars. They started with the Mars 1M probes. They tried launching two of them in 1960, but neither even made it to space. Another in 1962 was destroyed too.

They got close with Mars 1 in 1962, but it failed before it reached the planet, and Mars 2MV didn’t even leave the Earth’s orbit.

Five failures, one after the other, that must have been heartbreaking. Then the Americans took a crack at it with Mariner 3, but it didn’t get into the right trajectory to reach Mars.

Finally, in 1964 the first attempt to reach Mars was successful with Mariner 4. We got a handful of blurry images from a brief flyby.

For the next decade, both the Soviets and Americans threw all kinds of hapless robots on a collision course with Mars, both orbiters and landers. There were a few successes, like Mariner 6 and 7, and Mariner 9 which went into orbit for the first time in 1971. But mostly, it was failure. The Soviets suffered 10 missions that either partially or fully failed. There were a couple of orbiters that made it safely to the Red Planet, but their lander payloads were destroyed. That sounds familiar.

Now, don’t feel too bad about the Soviets. While they were struggling to get to Mars, they were having wild success with their Venera program, orbiting and eventually landing on the surface of Venus. They even sent a few pictures back.

Finally, the Americans saw their greatest success in Mars exploration: the Viking Missions. Viking 1 and Viking 2 both consisted of an orbiter/lander combination, and both spacecraft were a complete success.

Was the Mars Curse over? Not even a little bit. During the 1990s, the Russians lost a mission, the Japanese lost a mission, and the Americans lost 3, including the Mars Observer, Mars Climate Orbiter and the Mars Polar Lander.

There were some great successes, though, like the Mars Global Surveyor and the Mars Pathfinder. You know, the one with the Sojourner Rover that’s going to save Mark Watney?

The 2000s have been good. Every single American mission has been successful, including Spirit and Opportunity, Curiosity, the Mars Reconnaissance Orbiter, and others.

But the Mars Curse just won’t leave the Europeans alone. It consumed the Russian Fobos-Grunt mission, the Beagle 2 Lander, and now, poor Schiaparelli. Of the 20 missions to Mars sent by European countries, only 4 have had partial successes, with their orbiters surviving, while their landers or rovers were smashed.

Is there something to this curse? Is there a Galactic Ghoul at Mars waiting to consume any spacecraft that dare to venture in its direction?

Flying to Mars is tricky business, and it starts with just getting off Earth. The escape velocity you need to get into low-Earth orbit is about 7.8 km/s. But if you want to go straight to Mars, you need to be going 11.3 km/s. Which means you might want a bigger rocket, more fuel, going faster, with more stages. It’s a more complicated and dangerous affair.

Your spacecraft needs to spend many months in interplanetary space, exposed to the solar winds and cosmic radiation.

Arriving at Mars is harder too. The atmosphere is very thin for aerobraking. If you’re looking to go into orbit, you need to get the trajectory exactly right or crash onto the planet or skip off and out into deep space.

And if you’re actually trying to land on Mars, it’s incredibly difficult. The atmosphere isn’t thin enough to use heatshields and parachutes like you can on Earth. And it’s too thick to let you just land with retro-rockets like they did on the Moon.

Landers need a combination of retro-rockets, parachutes, aerobraking and even airbags to make the landing. If any one of these systems fails, the spacecraft is destroyed, just like Schiaparelli.

If I was in charge of planning a human mission to Mars, I would never forget that half of all spacecraft ever sent to the Red Planet failed. The Galactic Ghoul has never tasted human flesh before. Let’s put off that first meal for as long as we can.

Good News, Martian Colonists Can Eat All the Radishes They Want

When your stated purpose is to send settlers to Mars by 2026, you’re sure to encounter a lot of skepticism. And that is exactly what Dutch entrepreneur Bas Lansdorp has been dealing with ever since he first went public with MarsOne in 2012. In fact, in the past four years, everything from the project’s schedule, technical and financial feasibility, and ethics have been criticized by scientists, engineers and people in the aerospace industry.

However, Lansdorp and his organization have persevered, stating that they intend to overcome all the challenges in sending people on a one-way trip to the Red Planet. And in their most recent statement, MarsOne has announced that they have addressed the all-important issue of what their settlers will eat. In an experiment that feels like it was ripped from the The Martian, MarsOne has completed testing different types of crops in simulated Martian soil, to see which ones could grow on Mars.

Located in the Dutch town of Nergena, MarsOne maintains a glasshouse complex where they have been conducting experiments. These experiments took place in 2013 and 2015, and involved Martian and Lunar soil simulants provided by NASA, along with Earth soil as a control group.

Using these, a team of ecologists and crop scientists from the Wageningen University & Research Center have been testing different kinds of seeds to see which ones will grow in a Lunar and Martian environment. These have included rye, radishes, garden cress and pea seed. And earlier this year, they added a crop of tomatoes and potatoes to the mix.

As Dr. Wieger Wamelink, the ecologist who led the experiments, told Universe Today via email:

“We started our first experiment in 2013 (published in Plos One in 2014) to investigate if it was possible to grow plants in Mars and moon soil simulants. We assume that plants will be grown indoors, because of the very harsh circumstances on both Mars and moon, very cold, no or almost no atmosphere and way to much cosmic radiation. That first experiment only had a few crops and mostly wild plants and clovers (for nitrogen binding from the atmosphere to manure the soil).”

After confirming that the seeds would germinate in the simulated soil after the first year, they then tested to see if the seeds from that harvest would germinate in the same soil to create another harvest. What they found was quite encouraging. In all four cases, the seeds managed to germinate nicely in both Martian and Lunar soil.

“Our expectation were very low,” said Wamelink, “so we were very surprised that on the Mars soil simulant plants grew rather well and even better than on our nutrient poor control earth soil. There were also problems, the biggest that it was very difficult to keep the soil moist and that though on Mars soil simulant there was growth it was not very good, i.e. the amount of biomass formed was low.”

And while they didn’t grow as well as the control group, which was grown in Earth soil, they did managed to produce time and again. This was intrinsic to the entire process, in order to make sure that any crops grown on Mars would have a full life-cycle. Being able to grow crops, replant seeds, and grow more would eliminate the need to bring new seeds for every crop cycle, thus ensuring that Martian colonists could be self-sufficient when it came to food.

In 2015, they conducted their second experiment. This time around, after planting the seeds in the simulated soil, they added organic matter to simulate the addition of organic waste from a previous crop cycle. And on every Friday, when the experiments were running, they added nutrient solution to mimic the nutrients derived from fecal matter and urine (definite echoes of The Martian there!).

Once again, the results were encouraging. Once again, the crops grew, and the addition or organic matter improved the soil’s water-holding capacity. Wamelink and his team were able to harvest from many of the ten crops they had used in the experiment, procuring another batch of radishes, tomatoes and peas. The only crop that did poorly was the batch of spinach they had added.

This year, the team’s experiments were focused on the issue of food safety. As any ecologist knows, plants naturally absorb minerals from their surrounding environment. And tests have shown that soils obtained from the Moon and Mars show concentrations of heavy metals and toxins  – such as arsenic, cadmium, copper, lead, and iron (which is what gives Mars its reddish appearance). As Wamelink described the process:

Again we have ten crops, but slightly different crops from last year; we included green beans and potatoes (best food still and Mark Watney also seems to love potatoes). Also repeated was the addition of organic matter, to mimic the addition of the plant parts that are not eaten from a previous growth cycle. Also new is the addition of liquid manure, to mimic the addition of human faeces… We know that both Mars and moon soil simulants contain heavy metals, like led, copper, mercury and chrome. The plants do not care about this, however when they end up in the eaten parts then they could poison the humans that eat them. There we have to test if it is safe to eat them.”

And again, the results were encouraging. In all cases, the crops showed that the concentrations of metals they contained were within human tolerances and therefore safe to eat. In some cases, the metal concentrations were even lower than that found those grown using potting soil.

“We now tested four species we harvested last year as a preliminary investigation and it shows that luckily there are no harmful quantities present in the fruits, so it is safe to eat them,” said Wamelink. “We will continue these analyses, because for the FDA they have to be analysed in fresh fruits and vegetables, where we did the analyses on dried material. Moreover we will also look at the content of large molecules, like vitamins, flavonoids (for the taste) and alkaloids (for toxic components).”

However, the Wageningen UR team hopes to test all ten of the crops they have grown in order to make sure that everything grown in Martian soil will be safe to eat. Towards this end, Wageningen UR has set up a crowdfunding campaign to finance their ongoing experiments. With public backing, they hope to show that future generations will be able to be self-sufficient on Mars, and not have to worry about things like arsenic and lead poisoning.

As an incentive, donors will receive a variety of potential gifts, which include samples of the soil simulant used for the experiment. But the top prize, a a dinner based on the harvest, is being offered to people contributing €500 ($555.90 USD) or more. In what is being called the first “Martian meal” this dinner will take place once the experiment is complete and will of course include Martian potatoes!

Looking ahead, Wamelink and his associates also hope to experiment crops that do not rely on a seed-to-harvest cycle, and are not harvested annually.These include fruit trees so that they might be able to grow apples, cherries, and strawberries in Martian soil. In addition, Wamelink has expressed interest in cultivating lupin seeds as a means of replacing meat in the Martian diet.

And when it comes right down to it, neither MarsOne or the Wageningen UR team are alone in wanting to see what can be grown on Mars or other planets. For years, NASA has also been engaged in their own tests to see which crops can be cultivated on Mars. And with the help of the Lima-based International Potato Center, their latest experiment involves cultivating potatoes in samples of Peruvian soil.

For hundreds of years, the Andean people have been cultivating potatoes in the region. And given the arid conditions, NASA believes it will serve as a good facsimile for Mars. But perhaps the greatest draw is the fact cultivating potatoes in a simulated Martian environment immediately calls to mind Matt Damon in The Martian. In short, it’s a spectacular PR move that NASA, looking to drum up support for its “Journey to Mars“, cannot resist!

Naturally, experiments such as these are not just for the sake of meeting the challenges posed by MarsOne’s plan for one-way crewed missions to Mars. Alongside the efforts of NASA and others, they are part of a much larger effort to address the challenges posed by the renewed era of space exploration we find ourselves embarking on.

With multiple space agencies and private corporations (like SpaceX) hoping to put buts back on the Moon and Mars, and to establish permanent bases on these planets and even in the outer Solar System, knowing what it will take for future generations of colonists and explorers to sustain themselves is just good planning.

Go now and experience Hollywood’s blockbuster new space epic ‘The Martian’ helmed by world renowned director Ridley Scott and starring Matt Damon as the protagonist, NASA astronaut Mark Watney. And you can follow Watney’s dramatic fictional path across the Red Planet in newly released real photos and a flyover video of the region, from DLR and NASA, as it looks today.

‘The Martian’ is a mesmerizingly enjoyable cinematic triumph for everyone that’s all about science, space exploration and one man’s struggle to survive while left totally isolated on the Red Planet in the face of seemingly insurmountable odds – relying on his wits alone to endure “on a planet where nothing grows” while hoping somehow for a rescue by NASA four years in the future.

The movie combines compelling and plausible storytelling with outstanding special effects that’s clearly delighting huge audiences worldwide with a positive and uplifting view of what could be achieved in the future – if only we really put our minds to it!

Based on the bestselling book by Andy Weir, ‘The Martian’ movie from 20th Century Fox tells the spellbinding story of how NASA astronaut Mark Watney is accidentally stranded on the surface of Mars during the future Ares 3 manned expedition in 2035, after a sudden and unexpectedly fierce dust storm forces the rest of the six person crew – commanded by Jessica Chastain as Commander Lewis – to quickly evacuate after they believe he is dead.

Now you can follow the fictional exploits of Mark Watney’s stunningly beautiful trail across the real Mars through a set of newly released maps, imagery and a 3D video created by the DLR, the German Aerospace Agency, and NASA – and based on photos taken by the European Space Agency’s Mars Express orbiter and NASA’s Mars Reconnaissance Orbiter (MRO).

DLR’s stunning 3D overflight video sequence was created from a dataset of 7300 stereo images covering roughly two-and-a-half million square kilometres of precisely mapped Martian landscape captured over the past 12 years by Mars Express High Resolution Stereo Camera (HRSC). The electric score is by Stephan Elgner.

Video Caption: Following the path of The Martian – video generated using images acquired by the Mars Express orbiter. Scientists from German Aerospace Center, DLR– who specialise in producing highly accurate topographical maps of Mars – reconstructed Watney’s route using stereo image data acquired by the High Resolution Stereo Camera on board European Space Agency’s #MarsExpress spacecraft. They then compiled this data into a video that shows the spectacular landscape that the protagonist would see ‘in the future’ on his trek from Ares 3 at Acidalia Planitia/Chryse Planitia to Ares 4 at Schiaparelli Crater.

Ridley Scotts ‘The Martian’ takes place mostly on the surface of the Red Planet and is chock full of breathtakingly beautiful panoramic vistas. In the book you can only imagine Mars. In the movie Scott’s talents shine as he immerses you in all the action on the alien world of Mars from the opening scene.

Starting with the landing site for Watney’s Ares 3 mission crew at Acidalia Planitia, the book and movie follows his triumphs and tribulations, failures and successes as he logically solves one challenging problem after another – only to face increasingly daunting and unexpected hurdles as time goes by and supplies run low.

The DLR route map shows a real topographic view of Watney’s initial journey back and forth from the fictional Ares 3 landing site to the actual landing site of NASA’s 1997 Mars Pathfinder lander and Sojourner rover mission at the mouth of Ares Vallis.

The map continues with Watney’s months-long epic trek to the fictional landing site of Ares 4 Mars Ascent Vehicle (MAV) spacecraft at Schiaparelli Crater, by way of Marth Valles and other Martian landmarks, craters and valleys.

At the request of Andy Weir, the HiRISE camera on NASA’s MRO orbiter took photos of the Martian plain at the Ares 3 landing site in Acidalia Planitia, which is within driving distance from the Pathfinder lander and Sojourner rover in the book and movie.

This May 2015 image from the HiRISE camera on NASA's Mars Reconnaissance Orbiter shows a location on Mars associated with the best-selling novel and Hollywood movie, "The Martian." It is in a region called Acidalia Planitia, at the landing site for the science-fiction tale's Ares 3 mission.

The Martian is all about how Watney uses his botany, chemistry and engineering skills to “Science the sh** out of it” to grow food and survive until the hoped for NASA rescue.

Learning how to live off the land will be a key hurdle towards enabling NASA’s real strategy for long term space voyages on a ‘Journey to Mars’ and back.

‘The Martian’ is a must see movie that broadly appeals to space enthusiasts and general audiences alike who can easily identify with Watney’s ingenuity and will to live.

Since its worldwide premiere on Oct. 2, ‘The Martian’ has skyrocketed to the top of the US box office for the second weekend in a row, hauling in some $37.3 million. The total domestic box office receipts now top $108 million and rockets to over $228 million worldwide in the first 10 days alone.

I absolutely loved ‘The Martian’ when I first saw the movie on opening weekend. And enjoyed it even more the second time, when I could pick up a few details I missed the first time around.

The movie begins as the crew evacuates after they believe Watney was killed by the dust storm. Watney actually survived the storm but lost contact with NASA. The film recounts his ingenious years long struggle to survive, figure out how to tell NASA he is alive and send a rescue crew before he starves to death on a planet where nothing grows. Watney’s predicament is a survival lesson to all including NASA.

‘The Martian’ was written by Andy Weir in 2010 and the film could well break the October movie box office record currently held by ‘Gravity.’

The movie closely follows the book, which I highly recommend you read at some point.

By necessity, the 2 hour 20 minute movie cannot capture every event in the book. So there is an abbreviated sense of Watney’s detailed science to survive and lengthy overland trips.

All the heroics and difficulties in traveling to Pathfinder and back and getting communications started, as well as the final month’s long journey to Schiaparelli crater are significantly condensed, but captured in spirit.

The Martian is brilliant and intelligent and rivals Stanley Kubrik’s space epic ‘2001: A Space Odyssey’ as one of the top movies about humanities space exploration quest.

The one big science inaccuracy takes place right at the start with the violent Martian dust storm.

On Mars the atmosphere is so thin that the winds would not be anywhere near as powerful or destructive as portrayed. This is acknowledged by Weir and done for dramatic license. We can look past that since the remainder of the tale portrays a rather realistic architectural path to Mars and vision of how scientists and engineers think. Plus the dust storms can in fact kick up tremendous amounts of particles that significantly block sunlight from impinging on solar energy generating panels.

Personally I can’t wait for the ‘Directors Cut’ with an added 30 to 60 minutes of scenes that were clearly filmed – but not included in the original theatrical release.

THE MARTIAN features a star studded cast that includes Matt Damon, Jessica Chastain, Kristen Wiig, Kate Mara, Michael Pena, Jeff Daniels, Chiwetel Ejiofor, and Donald Glover.

“NASA has endorsed “The Martian’” Jim Green, NASA’s Director of Planetary Sciences, told Universe Today. Green served as technical consultant on the film.

The DLR film was created by a team led by Ralf Jaumann from the DLR Institute of Planetary Research, Principal Investigator for HRSC. He believes that producing the overflight video was not just a gimmick for a science fiction film:

“Mars generates immense fascination, and our curiosity continues to grow! Many people are interested in our research, and young people in particular want to know what it is really like up there, and how realistic the idea that one day people will leave their footprints on the surface of Mars truly is. The data acquired by HRSC shows Mars with a clarity and detail unmatched by any other experiment. Only images acquired directly on the surface, for instance by rovers like Curiosity, are even closer to reality, but they can only show a small part of the planet. Thanks to this animation, we have even noticed a few new details that we had not seen in a larger spatial context. That is why we made the film – it helps everyone see what it would be like for Watney to travel through these areas… the clouds were the only creative touches we added, because, fortunately, they do not appear in the HRSC data,” according to a DLR statement.

Here’s the second official trailer for The Martian:

As a scientist and just plain Earthling, my most fervent hope is that ‘The Martian’ will inspire our young people to get interested in all fields of science, math and engineering and get motivated to become the next generation of explorers – here on Earth and beyond to the High Frontier to benefit all Mankind.

Guide to October’s Conjunction Mania, See Venus in Daylight

Tomorrow morning might be a good time to call for extra celestial traffic control. A slip of a crescent Moon will join a passel of planets in the dawn sky for the first of several exciting conjunctions over the next few days.

In the space of three mornings beginning tomorrow,  four planets, the Moon and the star Regulus will participate in six separate conjunctions. Here’s how it’ll play out. Time are shown in UT / Greenwich Mean Time and Central Daylight and 1° equals two full moon diameters:

  • October 8: Venus 2.5° south of Regulus at 18 UT (1 p.m. CDT)
  • October 8: Regulus 3.1° north of the moon at 19 UT (2 p.m. CDT)
  • October 8: Venus 0.6° north of the moon at 20 UT (3 p.m. CDT)
  • October 9: Mars 3.2° north of the moon at 14 UT (9 a.m. CDT)
  • October 9: Jupiter 2.5° north of the moon at 21 UT (4 p.m.)
  • October 11: Mercury 0.8° north of the moon 11 UT (6 a.m. CDT)
The crescent Moon will be near Venus all day Thursday for the Americas until it sets in late afternoon, making for a great opportunity to catch sight of the planet in the middle of the day. This binocular view is for noon CDT Oct. 8 when the planet lies just shy of 2 from the Moon. Source:: Stellarium

Since several of the events occur in the middle of the afternoon for skywatchers in the Americas, here’s an expanded viewing guide:

* Thursday, October 8: Skywatchers will see Venus pass 2.5° south of Leo’s brightest star Regulus with a cool crescent moon a little more than 3° to the west of the brilliant planet. If you live in Japan and the Far East, you’ll see a splendidly close conjunction of the moon and Venus at dawn on October 9, when the pair will be separated by a hair more than one moon diameter (0.6°). At nearly the same time, the moon will be in conjunction with Regulus.

Observers in Australia and New Zealand will see the Moon occult Venus in a dark sky sky before dawn (or in daylight, depending on exact location) on the 9th. Click HERE for information, times and a map for the event.

* Friday, October 9: An even thinner moon passes about 3° north of Mars in the Americas at dawn and approximately 4° from Jupiter. Watch for the three luminaries to sketch a nifty triangle in the eastern sky 90 minutes to an hour before sunrise. Venus will gaze down at the planetary conclave 10° further west.

If you follow the moon to through its eastern descent, you'll be rewarded on Saturday morning (Oct. 11) with a fine pairing with Mercury. To see this conjunction, find a place with a good eastern horizon and bring binoculars to help you find the planet in bright twilight. Source: Stellarium

* Sunday, October 11: Mercury, which has quietly taken up residence again in the dawn sky, hovers 0.8° above a hair-thin moon this morning at 6 a.m. CDT. Best views will be about 45 minutes before sunrise, when the pair rises high enough to clear distant trees. Bring binoculars to help you spot the planet.

You’re thinking, why does this all have to happen in the morning? Thankfully, sunrise occurs around 7 a.m. for many locations, so you can see all these cool happenings in twilight around 6 a.m. — not terribly unreasonable. And now that the The Martian has finally hit the movie theaters, what better time to see the planet in the flesh? By pure coincidence, the location of stranded astronaut Mark Watney in the fictional account — Acidalia Planitia (Mare Acidalium) — will be facing dawn risers across the Americas and Hawaii this week.

October wraps up with a close grouping of three planets before dawn. This is the closest gathering of three planets since May 27, 2013. The next won't happen till January 10, 2021. Source: Stellarium

Dare I say this string of continuous conjunctions is only a warm-up for more to come? Earth’s revolution around the Sun quickly brings Jupiter higher in the eastern sky, while Mars races eastward as if on a collision course. The following Saturday on October 17, the two will meet in conjunction less than 1/2 degree (one Full Moon width) apart. Very nice!

But it gets even better. On Tuesday morning, October 27, you’ll see all three planets huddle at dawn. One degree will separate Jupiter and Venus with Mars bringing up the rear several degrees further east. Feast on the view because there won’t be a more compact arrangement of three planets again until January 10, 2021.

Matt Damon of ‘The Martian’ Explains NASA’s Journey to Mars – ISS Crew Previews Film on Orbit

The excitement is building for the worldwide movie premiere of ‘The Martian’ on Oct. 2.

Based on the bestselling book by Andy Weir, ‘The Martian’ tells the story of how NASA astronaut Mark Watney, played by Matt Damon, is accidentally stranded on the surface of Mars during a future manned expedition, after a sudden and unexpectedly fierce dust storm forces the rest of the crew to quickly evacuate after they believe he is dead.

In the video above, Matt Damon discusses NASA’s ongoing real life efforts focused on turning science fiction dreams into reality and sending astronauts to Mars.

Watney actually survived the storm but lost contact with NASA. The film recounts his ingenious years long struggle to survive, figure out how to tell NASA he is alive and send a rescue crew before he starves to death on a planet where nothing grows. Watney’s predicament is a survival lesson to all including NASA.

‘The Martian’ was written by Andy Weir in 2010 and has now been produced as a major Hollywood motion picture starring world famous actor Matt Damon and directed by the world famous director Ridley Scott from 20th Century Fox.

NASA’s overriding strategic goal is to send humans on a ‘Journey to Mars’ by the 2030s.

‘The Martian’ is a rather realistic portrayal of how NASA might accomplish the ‘Journey to Mars.’

“Sending people to Mars and returning them safely is the challenge of a generation,” says Damon in the video.

“The boot prints of astronauts will follow the rover tracks [of NASA’s Curiosity rover] thanks to innovations happening today.”

“NASA’s Journey to Mars begins on the International Space Station (ISS) .. where we are learning how humans can thrive over long periods without gravity.”

The current six person crew serving aboard the ISS even got a sneak preview of The Martian this past weekend!

Gleeful NASA astronaut Scott Kelly, commander of the Expedition 45 crew, just tweeted a photo of the crew watching ‘The Martian’ while soaring some 250 miles (400 kilometers) above Earth.

“Watched @MartianMovie on @Space_Station last night! Today working towards our #JourneyToMars during my #YearInSpace!” tweeted NASA astronaut Scott Kelly.

Kelly comprises one half of the first ever ‘1 Year ISS Crew’ along with Russian cosmonaut Mikhail Kornienko, aimed at determining the long term physical and psychological effects on the human body of people living and working in the weightlessness of space.

The 1 Year ISS mission is an important data gathering milestone on the human road to Mars since the round trip time to the Red Planet and back will take approximately 3 years or more.

In order to send astronauts to the Red Planet, NASA is now developing the mammoth Space Launch System (SLS) heavy lift booster and the Orion crew capsule to propel astronauts farther than ever before on the Journey to Mars.

The first unmanned test flight of SLS/Orion is slated for Nov. 2018. The first manned flight could occur between 2021 and 2023 – read my new report here.

“The Journey to Mars will forever change our history books … and expand our human presence deeper into the solar system,” says Damon.

THE MARTIAN features a star studded cast that includes Matt Damon, Jessica Chastain, Kristen Wiig, Kate Mara, Michael Pena, Jeff Daniels, Chiwetel Ejiofor, and Donald Glover.

“NASA has endorsed “The Martian’” Jim Green, NASA’s Director of Planetary Sciences, told Universe Today. Green served as technical consultant on the film.

I have read the book (I’m a professional chemist) and highly recommend it to everyone.

The Martian is all about how Watney uses his botany and chemistry skills to “Science the Sh.. out of it” to grow food and survive.

Learning how to live of the land will be a key hurdle towards enabling long term space voyages.

Kelly and his ISS cremates took a big first step towards putting that theory into practice when they recently grew, harvested and ate the first space grown NASA lettuce on the ISS using the Veggie experimental rack – detailed in my recent story here.

Are Martian Dust Storms Dangerous?

Just how dangerous are the terrifying dust storms that swarm Mars?

Brave explorers trek across the red dunes of Mars when a dangerous dust storm blows in. In moments, our astronauts are blasted by gale force winds and driving sand, reducing visibility to zero. The brave heroes stumble desperately through the driving onslaught, searching in vain for shelter from the catastrophic conditions. One is blown into a ravine, or right to the edge of the cliff, requiring a dramatic rescue and likely a terrible terrible sacrifice and important parting words showing the true mettle of our heroes.

“Tell my Asuka… printed body pillow… I loved her…”

Will they make it? Why the heck would anyone land on that dusty irradiated death trap? Actually, a better question might be “Why do writers lean so hard on this trope?”. I’m looking at you Andy Weir.

Martian dust storms don’t just come from the fevered imagination of the same sci-fi writer who gave us a lush Venusian jungle, Saturnalian lava flats and Moon floor cheese. These dust storms are all too real and they drive at serious windspeeds.

NASA’s Viking landers clocked them at 100 km/h during dust storm season. Which is a thing on Mars. The landers sheltered enough from the big storms that they probably didn’t experience the greatest winds they’re capable of.

Scientists have seen evidence that sand is shifted around on the surface of Mars, and the regolith requires high wind speeds to pick it up and shove it around. Dust devils spin up across the surface, and rotate at hurricane speeds.

When the wind is above 65 km/h, it’s fast enough to pick up dust particles and carry them into the atmosphere encasing the planet in a huge, swirling, shroud. Freaked out yet? Is this dangerous? It sure sounds dangerous.

Apologies to all the fearmongering sci-fi writers, but actually, it’s not that dangerous. Here’s why.

First off, you’re not on Mars. It’s a book. Second, it’s a totally different experience on Earth. Here when you feel the wind blasting you in the face, or watch it dismantle a house during a tornado, it’s the momentum of the air particles hammering into it.

That momentum comes from air particle density and their velocity. Sadly, the density of the atmosphere on Mars is a delicate 1% of what we’re used to. It’s got the velocity, but it just doesn’t have the density.

It’s the difference between getting hit by a garden hose and a firehose with the same nozzle speed. One would gets you soaked, the other can push you down the street and give you bruises.

To feel a slight breeze on Mars similar to Earth, you multiply the wind speed by 10. So, if the wind was going about 15 km/h here, you’d need to be hit by winds going about 150 km/h there to have the same experience.

It’s not impossible for winds to go that fast on Mars, but that’s still not enough wind to fly a kite. To get it off the ground your mission buddy holds the kite, and you run around in the dumb Martian sand like a try-hard ass.

It would fly for a second and then crash down. You’d wonder why you even brought a kite to Mars in the first place because it’s NEVER windy enough.

Boo hoo. Your Mars kite doesn’t work. Good news! You’re on Mars!
Bad news. It was a one way trip. Good news! A wizard has made you immortal!
Bad news. The wizard has brought to life the entire fictional cast of the Twilight series and they’re also there and immortal. Have fun brooding with your new dorky friends, FOR ETERNITY.

What I’m saying is you could stand on the red planet restaurant patio and laugh at anything the weather system could throw at you. That is unless, you’re solar powered.

Mars gets regular dust storms. From time to time, they can get truly global. In 2001, a storm picked up enough dust to shroud the entire planet in a red haze. Temperatures went up as dust helped trap heat in the atmosphere. This storm lasted for 3 months before temperatures cooled, and the dust settled back down again.

During a storm in 2007, dust blocked 99% of the light reaching the solar panels of the Opportunity rover. This severely decreased the energy it had to power its instruments, and most importantly, the heaters. Ultimately, it was possible that the cold could kill the rover, if the dust hadn’t subsided quickly enough.

If you happen to see a movie or read a book about an astronaut on Mars dealing with a dangerous dust storm, don’t worry. They’ll be fine, the wind won’t shred them to pieces. Instead, focus on unbreathably thin atmosphere, the bone chilling cold, or the constant deadly radiation.

That and where’s their food come from again? Well, now you know dust storms aren’t a big issue. Want to travel to Mars? Tell us in the comments below.

If you haven’t checked it out yet, go read “The Martian”. Jay and I loved the pants off it and we can’t wait to see the film version.

First Looks at The Martian Revealed

Alert: mild spoilers lie ahead, as we’ll be discussing minor plot points of the book The Martian. What, you haven’t read it yet? Have you been stranded on Mars? Don’t make us pull your geek card…

Never mind The Avengers or the seventh installment of the Star Wars franchise… some early stills from the big screen adaptation of Andy Weir’s The Martian have been circulating around ye ole web as of late, and we like what we see.

Self-published in 2012 and lauded for its scientific accuracy, The Martian follows the exploits of astronaut Marc Watney (played by Matt Damon in the upcoming film) as he struggles to stay alive on Mars. Watney must rally every bit of scientific expertise at his command to accomplish everything from growing food to establishing communications to surviving the disco music and bad 70s TV left behind by fellow crew members.

The 20 Century Fox film adaptation is directed by Ridley Scott (of Alien and Blackhawk Down fame) and promises to have a ‘successful failure’ vibe in the tradition of Ron Howard’s Apollo 13. Heck, reading The Martian, we simply love how it breaks the convention advocated at innumerable writing workshops that exposition is somehow always bad. Engineering and science geeks want to peek under the hood, and see what makes that warp drive tick. The Martian breaks very few rules when it comes to getting the science right, and there’s high hopes that this will translate well on the big screen.

From the design of Watney’s Mars excursion suit to the expedition rover he uses to cross the Martian terrain, we’re seeing lots of actual NASA designs being incorporated into the production.

“NASA was very involved in consulting for the film,” author Andy Weir told Universe Today. “The production got numerous people in both NASA and JPL involved and listened very closely to what they had to say.”

One of our favorite bits from the book is where Watney must use the rising and setting of the twin Martian moons Phobos and Deimos for a rough dead reckoning while travelling over the open Martian terrain. It’s a terrific scene with some possibilities for some great panoramic vistas, and we hope it survives into the film adaptation.

We also hope that the first NASA rover to roll across the soils of Mars (hint: it wasn’t Curiosity, Spirit or Opportunity) makes an appearance in the movie, as it did in the book.

The current release date set by 20th Century Fox is November 27, 2015 and Mr. Weir noted that we may be seeing the very first trailers for The Martian very soon, possibly in the June time frame.

And did you know? The cover for the script for The Martian—complete with early conceptual sketches by director Ridley Scott—actually flew aboard last year’s EFT-1 mission to test the Orion capsule in space.

Unlike trendy dystopian futures that are all the rage these days, The Martian depicts an optimistic future, a time where budgetary woes have been overcome and humans are living and working on Mars. This may well have been the true reason that the novel resonated so well throughout the science and space community: it conveys a message of a future that we all hope will be a reality in our lifetimes.

We even see a direct sci-fi lineage between The Martian and the classic 1954 science fiction tale The Cold Equations by Tom Godwin. The universe is indeed out to kill us, and only science can save the day.

It’ll be interesting to see if The Martian becomes the breakout hit of 2015. Also starring Michael Pena, Mackenzie David, Sean Bean, Donald Glover, Kate Mara, Sebastian Stan, Jeff Daniels, Chiwetel Ejiofor, and Jessica Chastain, The Martian features an all-star cast. We’re also curious to know if the film will have a disco soundtrack, but the author isn’t telling.

Much of the Mars-scapes for The Martian are being filmed in the deserts of Wadi Rum in southern Jordan. We traversed this region during our global backpacking trek in early 2007 and can attest that it is suitably Martian in appearance, though of course, we’ve yet to journey to the Red Planet… Weir’s book and the upcoming film will have to suffice for now.

Wadi Rum also simulated Mars in the films Red Planet and The Last Days on Mars.

We’ll definitely be waiting in line come opening day!
