Space Sunday: from Earth orbit to Pluto, via Mars

The second of the three so-called “supermoons” which see out 2016 produced some dramatic photographs and video from around the world. Perhaps one of the most stunning  came from cameras at the Baikonur Cosmodrome in Kazakhstan, monitoring Soyuz MS-03 as it stood on the pad at Launch Complex 1.

As I noted in my last Space Sunday Report, a “supermoon” occurs when the Moon is both full and at perigee – the point in its orbit when it is closest to the Earth as it travels around our planet in an elliptical orbit. Such events occur around every 14 months, and can see the Moon appear to be 14% bigger than its average size in our sky, particularly when seen low on the horizon.

The “supermoon” of November 14th was special because the Moon was about at its closest point to Earth in its orbit – “just” 356,509 kilometres (221,524 miles) from us and the Earth / Moon system is approaching the time of year when it is closest to the Sun (which will occur on January 4th, 2017), thus making the full Moon “extra” bright for those who were able to see it. The next time this will occur will be in 2034. However, December 14th will see another “supermoon”, albeit one at a slightly greater distance away from the Earth, so those who missed November’s – weather permitting – may still get to see one before the year is out. In the meantime, here’s NASA’s footage from Baikonaur  – the film obviously speeded-up 🙂 .

Soyuz MS-03 lifted-off from Baikonur on Friday, November 18th, carrying aloft Russian cosmonaut Oleg Novitskiy, American astronaut  Peggy Whitson and rookie French astronaut Thomas Pesquet. It successfully docked with the International Space Station on Saturday, November 19th, marking the start of the Expedition 50/51 mission aboard the station, the crew sharing space with the Expedition 49/50 crew of mission commander Shane Kimbrough of NASA and Russian cosmonauts Sergey Ryzhikov and Andrei Borisenko, who have been aboard the station since October and who are due to return to Earth in February 2017.

For Whitson, this is a double first: she is the oldest woman to ever fly to the ISS – she will celebrate her 57th birthday in orbit – and, come February, she will be the first woman to command the space station for a second time in its 16-year operational history, having already become the very first woman to take command during Expedition 16 in 2007. She is also NASA’s most experienced female astronaut, with nearly 377 days logged in space, including six space walks totalling 39 hours 46 minutes. By the time she returns to Earth, she will have spent more time in space than any other US astronaut, surpassing the 534-day record set by Jeff Williams in September 2016.

During their time aboard the station, Whitson, Novitskiy and Pesquest will conduct hundreds of experiments and studies in biology, biotechnology, physical science and Earth science. A particular focus will be recording how lighting impacts the overall health and well-being of station crew members, and how the microgravity environment in orbit affects tissue regeneration in humans and the genetic properties of space-grown plants.

The crew carry with them some special meal time treats as well. Taking a leaf from British astronaut Tim Peake’s book, Pesquest requested fellow countrymen and renowned chefs Alain Ducasse and Thierry Marx develop a special menu for the crew. Highlights include beef tongue with truffled foie gras and duck breast confit.

“We have food for the big feasts: for Christmas, New Year’s and birthdays. We’ll have two birthdays, mine and Peggy’s,” the Frenchman said at the astronauts’ last press conference before the launch.

Pesquest,  a former commercial airline pilot with Air France, is also set to offer some entertainment for the crew: a keen musician, he’s taken his saxophone to the ISS. As part of his work on the station, he has special responsibility for the Proxima research programme of 50 experiments developed by the European Space Agency and the French national space agency, CNES. The programme’s name was suggested by 13-year old Samuel Planas from Toulouse, France, following a nationwide competition among school children. It is taken from Proxima Centauri, with the X in the name both representing the unknown, and the fact that Pesquest is the tenth French astronaut to fly in space.

Oleg Novitskiy, a 45-year-old lieutenant colonel in the Russian Air Force, is also on his second mission aboard the ISS, having previously served as the Soyuz TMA-06M commander during the flight to the ISS, and as the station’s flight engineer during Expedition 33/34. He has spent 143 days 16 hours and 15 minutes in space.

Space Sunday: “super Earth”, “supermoon”, and Orion’s future

In a couple of recent Space Sunday reports, I covered the discovery of an Earth-size planet orbiting  our nearest stellar neighbour, the red dwarf Proxima Centuari (see here and here). Red dwarfs  are a class of star which has proven rich ground for planet hunters  –  and this has once again proved the case.

The European Southern Observatory ESO), one of the leading hunters of exoplanets, has  reported the discovery of a “super Earth”, a sold planetary body with roughly five times the mass of Earth. It is orbiting GJ 536, an M-class red dwarf star some 32.7 light years from the Sun. The planet is orbiting its parent once every 8.7 days, at a distance of 0.06661 AU.

The planet was discovered using a pair of instruments operated by ESO: the High Accuracy Radial velocity Planet Searcher (HARPS), mounted on ESO’s 3.6 metre telescope at the La Silla Observatory in Chile, and its sister instrument, HARPS-N, at the La Palma Observatory in Spain. The findings from these instruments were combined with photometric data from the All Sky Automated Survey (ASAS), which has observatories in Chile and Maui, to confirm the existence of the planet.

However, its was no rapid-fire discovery. In all, data from over eight years of observations of the star went into confirming the presence of the planet. Such is the extended period of observations, that the science team were able to gather a huge amount of spectroscopic data on the star. This has revealed it has a rotational period of about 44 days, and magnetic cycle that lasts less than three years. By comparison, the Sun has a rotational period of 25 days and a magnetic cycle of 11 years.

This indicates that GJ536 is, in keeping with most red dwarf stars, exceptional volatile. Such stars are so small, all activity within them is entirely convective in nature, which gives rise to massive stellar flares. So while the new planet may well have “earth” in its description, it is unlikely to be “Earth like”, particularly given its relatively close proximity to its parent star.

Not much more is known about the planet at this point, but this is liable to change over time, and in the meantime, the survey team will continue to gather data on GJ 536 to see if it is home to other planets, such as gas giants further away from it.

The last three months of 2016 are marked by three so-called “supermoons”, and the biggest will be in the night skies on Monday 14th November 2016.

The Moon is in an elliptical orbit around the Earth, at apogee, the point furthest from the Earth, it is between 404,000–406,700 km (252,500-254,187 mi) from Earth. At perigee, the point closest to the Earth, the Moon is between 356,400–370,400 km (222,500-231,500 mi) away. A “supermoon” occurs when the Moon is both full and at perigee, when it can appear up to 14% large in diameter than “normal” full moons.

“Supermoons” aren’t actually rare events; they take to occur once every 14 months on average.  However, the supermoon on November 14th, scores double. Not only will be “just” 356,509 kilometres (221,524 miles) from Earth, pushing it to that 14% increase in apparent size, but also because the Earth/Moon system is approaching the time of year when it is closest to the Sun (which will occur on January 4th, 2017). Therefore, the Moon will be receiving more sunlight than average, further boosting its apparent brightness.

Together, these two events mean that the Moon will be at its “largest” and brightest in the sky since 1948. The next comparable event will not occur again until 2034 – although there will be a further “supermoon” on December 14th, when the Moon again reaches its full phase, but it will be slightly further away from the Earth in its orbit at that time, so not quite as “super”.

Space Sunday: of moons, storms and rockets

A joint Belgian-French-Japanese study has provided the strongest evidence yet for the Martian moons being the result of a massive collision between the planet and other object very early in the solar system's history
The traditional theory of the Moon’s formation is that a Mars-sized body grazed the young Earth, throwing of a cloud of material which  eventually condensed into the Moon. Credit: NASA

We’re all familiar with the Moon, Earth’s cosmic companion. So familiar with it in fact, that we probably all think we know the theory behind how it got to be where it is – the result of a “giant impact” far back in Earth’s early history. However, a new study, published on October 31st in Nature, suggests what actually led to the creation of the Moon was possibly a lot  more elegant than previously realised.

The Moon is actually quite unique among the solar system’s satellites. It’s relatively large when compared to its parent planet, and it is a made of pretty much the same stuff, minus some more volatile compounds that evaporated long ago. Other moons tend to be a lot more chemically diverse when compared to one another and their parent worlds.

The accepted theory of lunar formation has it that not long after primordial Earth formed, a Mars-sized object grazed it, throwing off a mass of material from which the Moon subsequently condensed. This impact set the angular momentum for the Earth-moon system, and gave the early Earth a five-hour day. Then, over the aeons, the Moon slowly receded from the Earth (as it continues to do so to this day), and Earth’s rotation has slowed to our current 24-hour day.

The Moon is is an elliptical orbit around the Earth which varies from 364,397 km at its closest, to 406,731 km at its most distant. When it’s full and at its closest point to Earth (perigee), the Moon can look over 10% bigger, and 30% brighter than when it’s at a more distant point in its orbit (apogee). However, such is the momentum of the Moon's oribt, it is actually slowly moving further and further away from Earth, as it has been throughout its history

It’s a theory all worked out be a combination on mathematics based on the moon’s current orbit, the angular momentum of the Earth-Moon system, the influence of various tidal forces, a little bit of guesswork, etc.  However, it does have a couple of holes in it.

The first is that if the Moon was formed as a result of material set free during a slight collision between Earth and another body, then that material should have been a mix of debris from both Earth and the other body, giving rise to a lunar composition that should be at least somewhat different to that of Earth. The second is that if the Moon condensed from a disk of material rotating around Earth’s equator, it should be in orbit over the equator – but instead, its orbit is tilted 5 degrees off the equator.

Both of these issues have previously been explained in terms of “intervening steps” between what we see today and the original  “giant impact”. However, a team of scientists led by Sarah Stewart, professor of earth and planetary sciences at the University of California, have posited an alternative explanation, which requires no “intervening steps”, but always natural mechanics to explain everything.

In their model, the “giant impact” still occurs –  but it completely destroys the nascent Earth and whatever hit it, leaving a mass of vaporised and molten material  orbiting the Sun, which eventually condenses to form a “new” Earth and the Moon – thus giving them similar chemical compositions. Initially, the Earth would have likely been tipped so its axis was pointing towards the Sun while spinning in a two-hour day.

Then, as angular momentum was dissipated through tidal forces, the Moon started receding from Earth, eventually reaching a point called the “LaPlace plane transition”. At this point the forces from the Earth on the Moon became less important than gravitational forces from the sun, resulting in some of the angular momentum of the Earth-Moon system transferring to the Earth-Sun system, causing the Earth to tip “upright”, while leaving the Moon in a very highly inclined orbit relative to Earth’s equator. However, as the Moon continued to slowly and naturally recede from the Earth, it eventually reached the Cassini transition, gradually reducing the Moon’s angle of inclination relative to the Earth’s equator, bringing it to the five-degree offset we see today.

Thus, with this model, no exotic intermediary steps are required to account for the Moon’s composition or why it is where it is today; everything can be explained through the application of mathematics and planetary mechanics, offering a compelling alternative to the accepted theory of lunar evolution.

China’s newest and biggest heavy-lift rocket, the Long March 5 (Chang Zheng-5) lifted-off from the Wenchang launch centre on Hainan Island, off China’s southern coast, at 12:43:14 UT or 20:43 Beijing time on Thursday, November 3rd, carrying an experimental satellite designed to test electric-propulsion technology.

With a 25 tonne low Earth orbit payload capacity, the Long March 5 stands on a par with the current crop of heavy lift launch vehicles in operation around the world. The product of two decades of research and development, it is destined to become a centrepiece of China’s growing space ambitions.

Among its may missions, the Long March 5 will play a leading role in the construction of China’s upcoming space station, starting with the launch of the core Tianhe (“Harmony of the Heavens”) module in 2018. When completed in 2022, the 60-tonne station will comprise the core module supported by the Wentian (“Quest for the Heavens”) and Mengtian (“Dreaming of the Heavens”) pressurised experiments modules, all of which will be linked by a multi-port adaptor / EVA airlock.

Space Update: Planet Nine, “signalling” stars and a quick round-up

In January and February 2016, I wrote about Planet Nine (or Planet X, George, Jehoshaphat, or Planet of the Apes, depending  your preference), the Neptune-sized world believed to be orbiting the sun on the very edge of the solar system in a highly eccentric orbit. Since then, the search for this mysterious world has continued, and while it has yet to be located, evidence that it exists has been mounting. Not only that, but astronomers now believe it might explain why the solar system is “tipped”.

The Hunt started after Mike Brown, a leading planetary astronomer at the California Institute of Technology (Caltech), and his colleague Konstantin Batygin developed a computer model which showed that the very eccentric orbits of six Trans-Neptunian Objects (TNOs) located in what is called the scattered disk,  a sparsely populated region of space between 30 100 AU from the sun, overlapping with the Kuiper belt, could have been due to the influence of a massive, distant planet. At the time, they noted that if the model was correct, other TNOs would likely  occupy equally distinct orbits.

At the joint European Planetary Science Congress (EPSC) and American Astronomical Society’s Division for Planetary Sciences (DPS) in October, it was revealed more TNOs fitting the model have been discovered over the past several months. Two of them,  2013 FT28 and 2014 SR349, precisely fit the same type of orbit seen the original six objects used by Brown and Batygin model. Five more have been found in orbits which are effective perpendicular to Planet Nine’s believed orbit around the Sun, something predicted by the computer model.

All of this is helping to narrow down Planet Nine’s potential orbit around the Sun, and the arc of that orbit where it might be found. So much so that Batygin, Brown have teamed with original proponents for Planet Nine Chad Trujillo and Scott Sheppard to use the 8-metre Subaru Telescope atop Mauna Kea in Hawaii to carry out a  search of the night sky. Sheppard and Trujillo are also using two telescopes in Chile to search the possible sweep of the planet through the southern hemisphere’s night sky. And they are not alone.

The Brown / Batygin model for Planet Nine indicated the planet would cause some TNOs to ine in orbits perpendicular to the planet's own eccentric orbit around the Sun - and five such object have now been discovered (shown in teal, with the original TNOs possibly influenced shown in magenta.

Also at the planetary conference, graduate student Elizabeth Bailey, using Brown and Batygin’s data presented a paper proposing how the odd tilt to the solar system’s major planets relative to the Sun might be due to Planet Nine.

With the exceptional of Mercury, all the major planets in the solar system orbit along a plane tilted by about six degrees from the Sun’s equator. This suggests either the Sun was somehow tipped on its axis in the past, or the planets have been pulled from their original alignment along the Sun’s equatorial plane. Of these two ideas, the preferred option has been for exotic interactions between the early Sun’s magnetic field and the primordial disk of gas surrounding it, inclining the latter, which then formed the planets. However, Bailey’s simulations suggest that a large body occupying Planet Nine’s predicted orbit could have had sufficient influence on the Sun over some 4 billion years to have slowly tipped it over by six degrees. Bailey’s hypothesis was supported by a  Brazilian team of astronomers, who used a different analytical method while working independently from her, and reached the same conclusion.

Even so, some remain sceptical that the mysterious world exists. “I give it about a 1% chance of turning out to be real,” says astronomer JJ Kavelaars, of the Dominion Astrophysical Observatory in Victoria, Canada. Interestingly, his fellow researcher and collaborator Cory Shankman,  has created models with the exact orbits of the original six TNOs used by Brown and Batygin, and found that a massive planet would not maintain their tell-tale clustering for long periods.

Thus, the search for the solar system’s mysterious Planet Nine, continues.

ETs Phone Home?

Are aliens sending signals using their own stars? That’s what might be happening, according to astrophysicists Ermanno Borra and Eric Trottier, from Laval University in Quebec; although they admit it’s only one possible explanation for what they appear to have discovered.

It was in 2012 that Borra predicted intelligent aliens might use the light from their own stars to signal their existence to the cosmos. Using data from the Sloan Digital Sky Survey, Borra and Trottier analysed the spectra of 2.5 million stars to see if this might be the case – and found 234  which seem to be broadcasting a signal of the kind predicted by Borra.

The “signals” are pulses in the stars’ light, separated by a constant time interval. What’s more, all 234 stars are predominantly in the F2 to K1 spectral range, which is the small range of stars centred on the spectrum of our own life-supporting Sun, and thus the broad group of stars thought might support life on planets orbiting them.

However, as Borra and Trottier note in their paper – which has yet to be comprehensively peer-reviewed – the pulses could be the result of natural factors such as rotational transitions in molecules or the Fourier transform of spectral lines. It might even be due to rapid pulsations in the stars themselves. Nevertheless Borra and Trottier have tended to dismiss rotational transitions on the grounds that such behaviour isn’t common to these types of star. They also think it unlikely a Fourier transform is responsible.

Instead, they lead towards either the “signals”  being an artefact produced by data reduction on the part of the Sloan instrument, or the work of ET, with a slight emphasis towards the ET side of their thinking.  Others, having read their paper, are far more sceptical.

“It seems unlikely that 234 separate alien societies would be sending out such similar signals more or less simultaneously” Seth Shostak, a senior astronomer at the SETI (Search for Extraterrestrial Intelligence) Institute in Mountain View, California said. “It would be like expecting us to send the same signals as the Abyssinians — it doesn’t make a whole lot of sense.” Instead, Shostak leans towards the data reduction explanation; as does Occam’s Razor.

But a further possible explanation has been suggested: that the signals are due to highly peculiar chemical compositions in a small fraction of galactic halo stars which has  never been previously encountered. While not as exotic as aliens using their stars as signalling devices, should this prove to be the case, it would still be a remarkable new discovery.

Philosophical frenemies: Altberg and Rosedale

Yesterday, a Tweet from Jo Yardley pointed me to an interesting article in Wired by Rowland Manthorpe, entitled Second Life was just the beginning. Philip Rosedale is back and he’s delving into VR. It’s a lengthy, fascinating piece, arising out of a week Manthorpe spent with High Fidelity, while also taking time to poke his head around the door of Linden Lab, offering considerable food for thought – and it kept me cogitating things for a day, on-and-off.

There’s some nice little tidbits of information on both platforms scattered through the piece. For those that have tended to dismiss High Fidelity as a place of “cartoony” avatars, the images provided with the article demonstrate that High Fidelity are walking along the edge of the Uncanny valley; compare the Rosedale-like figure seen the a High Fidelity promo shot within it with a photo of the man himself (below). There’s also further indication that in terms of broader creativity and virtual space, High Fidelity is “closer” to the Second Life model of a virtual world than Sansar will be.

On the Lab’s side of things, we also get confirmation that multiple instances of the same space in Sansar will not be in any way connected (“One school group visiting the Egyptian tomb won’t bump into another – they will be in separate, identical spaces.”). There’s also a hint that Linden Lab may still be looking at Sansar as a “white label” environment.

High Fidelity can still be critiqued by some in SL for it's "cartony" avatar. The reality is however, that for those who wish, avtars in High Fidelity can be extremely life-like, as this picture of what Philip Rosedale might look like in High Fidelity (r) shows when compared to an actual photograph of him.

But what really makes the piece interesting is the philosophical differences apparent in developing these platforms; each is very much rooted in the nature of the man at the helm of each company.

Rosedale is a dreamer – and that’s not a negative statement. He’s been driven by “dreams” and “visions” throughout most of his post Real Networks career. He also leans heavily into the collaborative, open borders model of development. Both have influenced the working spaces he builds around him. Reading Manthorpe’s piece, the High Fidelity office appears to be run along a similar laissez-faire approach as marked the early years at Linden Lab:  people dabble in what interests them, focused on the technology; there’s a belief that if the company cannot solve a problem (such as practical in-world building using hand controllers), someone “out there” will, and all will be well.

By contrast, Altberg is more consumer / direction oriented with Sansar. Initial market sectors have been identified, work has been broken down into phases. A structured development curve has been set; as we’ve seen from Lab Chat and other sessions, there’s a reasonably clear understanding of what should be tackled first, and what can be pushed further down the development path. The platform itself is closed, controlled, managed.

Sansar Screen Shot, Linden Lab, August 2016, on Flickr Sansar (TM) Screen Shot, Linden Lab, October 2016, on Flickr

In adopting these approaches, and given their somewhat complicated business relationship (Rosedale still have “sizeable” financial holding in Linden Lab; linden Lab was one of the small investors in High Fidelity’s $2.4 million round of seed funding), Rosedale and Altberg describe their relationship as “frenemies”. They are both working towards similar goals, and dealing with the same consumer-facing technology, and are equally sniffy of the other’s product. Rosedale sees Sansar is being potentially too closed, too pigeon-holed in terms of how it will be perceived by consumers; Altberg sees High Fidelity as being to focused on the technology, and perhaps demanding more effort than most on-line consumers in the Facebook pre-packaged content age might be willing to invest.

When looked at from outside, the Rosedale / High Fidelity approach is perhaps more in keeping with the state of VR once all the hyperbole surrounding it is brushed aside:  VR may well be part of our future, but no-one can honestly say at this point just how big a part of our future it will be. The Altberg / Linden Lab approach is rooted business pragmatism: identify your markets and seek to deliver to those markets; build your product to reflect the market as it grows.

Neither approach is necessarily “right” or “wrong”, and there is certainly no reason why both cannot attract their own market share. But I have to admit I find myself leaning more in Altberg’s direction.

This is admittedly partly because a lot of Rosedale’s broader comments about High Fidelity, the Internet, etc., come across as re-treads of things said ten years ago about Second Life and a transformative future never realised. But it’s more particularly because  – as noted above – no-one really knows how pervasive VR will be on a broad level. Other technologies such as augmented reality (AR) and mixed reality (MR) currently lie within the shadow cast by the hyperbole surrounding VR, but have the potential for far greater impact in how we conduct our lives and business. So identifying a market share and aiming for it seems to be the more solid approach insofar as establishing a user base and revenue flow might be concerned*.

Time will obviously tell on this; but one fact is clear: however you regard the philosophies held by Rosedale and Altberg, Manthorpe’s article is a must read. A considered, well presented, in-depth piece, it is sits as a catalyst for considerable thought and potential discussion.
