Apollo 11 moon landing anniversary

Filed under: History, Space, USA — Tags: , , , — Nicholas @ 10:42

The first men walked on the moon on this day in 1969:

Astronaut Buzz Aldrin, lunar module pilot, stands on the surface of the moon near the leg of the lunar module, Eagle, during the Apollo 11 moonwalk. Astronaut Neil Armstrong, mission commander, took this photograph with a 70mm lunar surface camera. While Armstrong and Aldrin descended in the lunar module to explore the Sea of Tranquility, astronaut Michael Collins, command module pilot, remained in lunar orbit with the Command and Service Module, Columbia. *This is the actual photograph as exposed on the moon by Armstrong. He held the camera slightly rotated so that the camera frame did not include the top of Aldrin's portable life support system ("backpack"). A communications antenna mounted on top of the backpack is also cut off in this picture. When the image was released to the public, it was rotated clockwise to restore the astronaut to vertical for a more harmonious composition, and a black area was added above his head to recreate the missing black lunar "sky". The edited version is the one most commonly reproduced and known to the public, but the original version, above, is the authentic exposure.

I didn’t realize that almost all the Apollo 11 photographs of astronauts are of Buzz Aldrin. For some reason, Neil Armstrong appears in only a few of them, and The Atlantic‘s Rebecca Rosen wonders why:

Bootprint in lunar dust created and photographed by Buzz Aldrin for the boot penetration (soil mechanics) task during the Apollo 11 moon walk.

Bootprint in lunar dust created and photographed by Buzz Aldrin for the boot penetration (soil mechanics) task during the Apollo 11 moon walk.

If there is one thing everybody knows about Neil Armstrong, it is this: “One small step for [a] man, one giant leap for mankind.” This quotation, in my mind at least, appears illustrated, conjuring the image above of an imprint left by a human boot upon the dusty lunar surface.

Except that’s not the first step, nor was it left by Armstrong. It’s a footprint made by Buzz Aldrin, the second man to walk on the moon.

[…]

The explanation for this paucity is murky at best, prone to the uncharitable reading that Aldrin was getting “Armstrong back by taking no photographs of him on the Moon” in retribution for Armstrong getting the honor of first to set foot on the lunar surface.

But this is speculation at best. Aldrin, at least, has always said that the lapse was inadvertant, the result of Armstrong carrying the camera most of the time, a picture of Armstrong not appearing on the bucket list of things to do while on the moon, and Armstrong never stopping to ask for one. According to Aldrin, he was about to take a picture of Armstrong at the flag ceremony when President Nixon called, distracting them from the task.

[…]

Later, Aldrin expressed regret about the oversight. “When I got back and someone said, ‘There’s not any of Neil,’ I thought, ‘What in the hell can I do now?’ I felt so bad about that. And then to have somebody say that might have been intentional…. How do you come up with a nonconfrontational argument against that? I mean, that was just such a divisive observation, and Neil and I were never in the least divisive. We really were intimidated by the situation we found ourselves in on the Moon, hesitant and with an unclear idea of what to do next.”

Hansen’s book includes a handful of divergent opinions from different NASA administrators, theorizing as to how this, what Hansen calls “one of the minor tragedies of Apollo 11,” could have happened. Was it mere oversight or petty payback? Men sticking close to the plan or men sticking too close to the plan?

Russian rocket export ban means increasing opportunities for private enterprise in space

Filed under: Russia, Space, Technology, USA — Tags: , , , , — Nicholas @ 09:46

Strategy Page looks at the knock-on effects of the Russian government banning the export of rocket engines to the United States:

The U.S. government is being forced to use satellite launchers developed without government financing because the usual methods of obtaining these launchers is falling apart and currently is unable to supply enough rockets to get all American military satellites into orbit. The immediate cause of this problem is the recent (since earlier this year) Russian aggression against Ukraine. The U.S. responded to this aggression by placing sanctions on some Russian officials and firms. Russia responded to that by halting RD-180 shipments to the United States. That’s breach of contract and it will do enormous damage to Russian exports in the future because now many countries and firms realize that a contract with a Russian firm can be cancelled by the Russian government for any reason. This was always seen as a risk when doing business with Russia and many Western firms declined to do so or have pulled out of Russia in the last decade because of the growing unreliability of Russia as a business partner. The RD-180 affair got a lot of publicity, all of it bad with regard to future Russian exports of high-end industrial items. Europe, which gets about a third of its natural gas from Russia, is already looking for alternate sources and investors are fleeing Russia (and taking their money with them).

[…]

This is good news for the new private firms that are developing rockets for launching stuff into orbit. One such firm is SpaceX (Space Exploration Technologies Corporation) and is has been trying to break the current cartel controlling U.S. government satellite launch services. Since 2006 all this business has gone to a government-approved monopoly called the ULA (United Launch Alliance) which is composed of Lockheed Martin (Atlas 5 rocket) and Boeing (Delta 4). These two firms have dominated U.S. space launches for over half a century. Because of the RD-180 the Atlas 5 is more attractive (in terms of performance and price) than the Delta 4. Meanwhile SpaceX expects to have Atlas 5 competitor ready in a few years.

In 2012 SpaceX obtained its first contract to launch U.S. military cargo into space. SpaceX had earlier obtained a NASA contract which included 12 deliveries to the International Space Station (at $134 million each). What makes all this so noteworthy is that SpaceX developed its own launch rockets without any government help. SpaceX also developed the Dragon space vehicle, for delivering personnel and supplies to the International Space Station.

SpaceX has since proved that its rockets work and is pointing out that the SpaceX rockets can do the job cheaper that ULA. Currently ULA gets a billion dollar a year subsidy from the government that SpaceX would not require. SpaceX still has to get all the paperwork and approvals done so that they can handle classified missions. SpaceX does not see this as a problem, it’s simply going to take another year to satisfy all the bureaucrats and regulations.

Russia, the United States, and the ISS – an opening for SpaceX

Filed under: Europe, Russia, Space, USA — Tags: , , — Nicholas @ 11:48

Motherboard‘s Jason Koebler says that Russia’s threat to ban companies from shipping rocket engines to the US represents a great chance for SpaceX to cash in:

Russia just announced plans to shut down the International Space Station in 2020, and prohibited companies in the country from selling engines to Lockheed Martin and Boeing for military launch purposes. If this is more than just posturing, there’s at least one takeaway: SpaceX is about to get paid.

It was just a month ago that NASA Administrator Charles Bolden said that Russia would never ban the United States from the ISS, and that his “contingency plan” for getting astronauts to and from the ISS was to continue working with Russia as normal until an American company is ready to fly manned flights to the ISS in roughly three years.

[…]

And that brings us to SpaceX. The company stands to gain greatly from both bits of news Rogozin announced today.

The company recently won (and then subsequently lost) an injunction to force the United States Air Force to compete for military satellite launch contracts. If Boeing and Lockheed Martin are blocked from buying Russian engines for their Atlas V and Delta IV from the other side (it’s worth noting that both countries have threatened to ban the companies from buying Russian engines), the Air Force once again has incentive to look at SpaceX as a legitimate option to launch military satellites.

The Air Force’s contract with the Boeing-Lockheed cooperative United Launch Alliance is worth roughly $70 billion through 2030 — SpaceX could potentially swoop in and take some of that amid the uncertainty.

SpaceX and the successful re-entry experiment

Filed under: Space, Technology — Tags: , , , , — Nicholas @ 07:58

Amanda Wills talks about the most recent SpaceX achievement:

When SpaceX launched its Dragon supply mission to the International Space Station on April 18, it tried something revolutionary after the spacecraft was safely in orbit.

Behind the scenes, CEO Elon Musk and his team had been testing the reusability of this rocket. On that Friday, the team returned part of it to Earth for the first time in history. Once Dragon was in space, the first stage separated and re-entered Earth’s atmosphere. As the helium-filled rocket slowed, it extended four 25-foot-long landing legs and used its thrusters to briefly hover over the Atlantic Ocean before plopping down ever so gently onto its surface.

Musk and his team pulled it off — a huge feat considering that the chance of success was only around 30% to 40%. The SpaceX team recovered the raw video from the camera that was on board Falcon 9, and software engineers have spent the last week trying to repair the footage, which was taken just before splashdown.

[…]

The team was able to bring back the first stage. The rocket was clearly vertical — an important detail in testing reusable rockets — and the soft landing was successful. However, the weather wasn’t cooperative that day and the stage was destroyed by rough waves. Fortunately, Musk said his team was able to recover bits of the rocket.

SpaceX Falcon F9R First Flight Test | 250m

Filed under: Space, Technology — Tags: — Nicholas @ 11:43

Published on 18 Apr 2014

Video of Falcon 9 Reusable (F9R) taking its first test flight at our rocket development facility. F9R lifts off from a launch mount to a height of approximately 250m, hovers and then returns for landing just next to the launch stand. Early flights of F9R will take off with legs fixed in the down position. However, we will soon be transitioning to liftoff with legs stowed against the side of the rocket and then extending them just before landing.

The F9R testing program is the next step towards reusability following completion of the Grasshopper program last year (Grasshopper can be seen in the background of this video). Future testing, including that in New Mexico, will be conducted using the first stage of a F9R as shown here, which is essentially a Falcon 9 v1.1 first stage with legs. F9R test flights in New Mexico will allow us to test at higher altitudes than we are permitted for at our test site in Texas, to do more with unpowered guidance and to prove out landing cases that are more-flight like.

ISS resupply mission successfully launched

Filed under: Space — Tags: , , , — Nicholas @ 09:45

And another story from yesterday that I would have covered:

SpaceX shoots off the launch pad right on time

SpaceX shoots off the launch pad right on time

The Falcon 9 rocket lifted off from Cape Canaveral on schedule at 12:35pm PDT (8:35pm UTC), carrying 5,000 pounds of supplies for the ISS. The first stage separated cleanly two minutes and fifty one seconds into the flight, 103km above the launch pad, and the Dragon capsule has deployed its solar panels and is now on course to dock with the ISS in two days, once orbital paths have matched up.

It was a very close run thing. The CRS-3 mission was due to take off on Tuesday but was cancelled after a helium leak was detected. Friday’s launch was much tighter, and SpaceX said the launch had a one-second window if the rocket was to successfully insert its cargo into the right orbital plane.

Weather was a big worry for the SpaceX team. There was rain and relatively heavy clouds at the launch site, and the team floated multiple weather balloons into the upper atmosphere to make sure that winds weren’t too strong at altitude.

Unfortunately, the heavy winds and storm conditions in the Atlantic may hamper the second part of Friday’s mission: the remote landing of the first stage of the Falcon 9 rocket. After separating, the booster is planned to fire up again and slow down, falling back towards the Earth.

If all goes well, the rocket will then deploy four legs, which were covered for the initial launch phase, and begin a controlled burn to slowly sink towards the ocean and hover for landing and retrieval. At least, that was the plan.

But the inclement weather means the SpaceX support ship that was due to witness the rocket’s return and retrieve the hardware couldn’t get into position. SpaceX says it will attempt the soft landing anyway, but there’s no word yet on its success or otherwise.

SpaceX to test hover capability on next launch

Filed under: Space, Technology — Tags: , , , — Nicholas @ 08:25

In The Register, Brid-Aine Parnell explains what will be different about the next SpaceX launch to resupply the ISS:

NASA has said that SpaceX’s latest cargoship launch to the International Space Station will go ahead, despite a critical computer outage on the station, allowing the firm to test the craft’s hovering abilities.

[…]

The booster rocket that’s blasting the Dragon supply capsule into space is going to attempt to make a hovering soft landing after it’s disengaged and dropped back to Earth.

The spruced-up Falcon 9 has its own landing legs, which Elon Musk’s space tech company hopes will eventually make for precise set-downs on the surface of alien worlds. For this test though, the rocket will still be coming down over the ocean, just in case.

The launch is already a month late with its nearly 5,000 pounds of supplies and payloads, including VEGGIE, a new unit capable of growing salad vegetables for the ‘nauts to munch on. The ship was delayed from March after a ground-based radar system at Cape Canaveral was damaged.

Scientific facts and theories

Filed under: Environment, Science, Space — Tags: , , , , — Nicholas @ 10:32

Christopher Taylor wants to help you avoid mis-using the word “fact” when you’re talking about “theories”:

These days, criticizing or questioning statements on science can get you called an idiot or even a heretic; science has become a matter of religious faith for some. If a scientist said it, they believe it, and that’s that. Yet the very nature about science is not to be an authoritative voice, but a method of inquiry; science is about asking questions and wondering if something is valid and factual, not a system of producing absolute statements of unquestioned truth.

It is true that people need that source of truth and it is true that we’re all inescapably religious creatures, so that will find an outlet somewhere. Science just isn’t the proper outlet for it.

[…]

The problem is that there’s no way to test or confirm this theory [plate tectonics]. You can make a model and see it work, you can check out types of rock and examine fault lines, and you can make measurements, but that’s only going to tell you small portions of information in very limited time frames. Because the earth is so huge, and because there are so very many different pressures and influences on everything on a planet, you can’t be sure without observation over time.

And since the theory posits that it would take millions of years to really demonstrate this to be true, humanity cannot test it enough to be certain. So all we’re left with is a scientific theory: a functional method of interpreting data. In other words, it cannot be properly or accurately describe as fact.

This is true about other areas. The word “fact” is thrown around so casually with science and is defended angrily by people who really ought to know better. Cosmology does this a lot. Its a fact that the universe is expanding from an unknown central explosive point (although there is a fair amount of data that’s throwing this into question). We can’t know because we can’t have enough data and there hasn’t been long enough to really test this.

Michael Crichton’s criticism of global warming was along these lines. He didn’t deny anything, he just said its too big and complex a system that we understand far too little about to even attempt to make any absolute or authoritative statements about it. Science has gotten us far beyond our ability to properly measure or interpret the data at hand, but some still keep trying to make absolute statements anyway.

[…]

And that’s the heart of a scientific theory. It isn’t like a geometric theorem (a statement or formula that can be deduced from the axioms of a formal system by means of its rules of inference), or a theory that Sherlock Holmes might develop (a proposed explanation whose status is still conjectural). A scientific theory is a system of interpreting data (a coherent group of general propositions used as principles of explanation for a class of phenomena). It’s a step beyond a hypothesis, which is simply speculation or a guess, but is not proven fact.

Confusing theory with fact is really not excusable for an educated person, but some theories are so wedded to worldviews and hopes that they become a matter of argument and even rage. Questioning that theory means you’re an idiot, uneducated, worthless. If you doubt this theory, you’re clearly someone who is wrong about everything and should be totally ignored in life, even showered with contempt.

For all its rich vocabulary, English fails to correctly differentiate among the various uses of the word “theory”, which allows propagandists and outright frauds to confuse the issues and obscure the difference between what science can say about an issue and what believers desperately want to be true.

Forbes talks to Warren Ellis

Filed under: Books, Media, Space — Tags: , , , — Nicholas @ 00:01

Warren Ellis has a new novella out (that I haven’t read yet) and talks to Alex Knapp about the new work and other topics:

In Dead Pig Collector, the process of disposing of a body is fairly well detailed. How much research did you do for that?

Four or five hours. Believe it or not, a lot of people seem to spend time talking on the internet about getting rid of bodies. And now they’re all on PRISM-generated watchlists. And so am I.

One of the things that’s fascinating about your work is that it explores subcultures that seem like fantasy, but very much exist in real life. I know, for example, a lot of the cultures you explored in Crooked Little Vein are horribly true. What interests you about them?

I think one of the bigger lessons the internet has taught us is that “niche” or “subculture” are a lot bigger than anyone ever thought. And, frankly, if it’s on the internet, the biggest and widest communication and information system in the world, then it’s not really a subculture any more. If it’s accessible by hundreds of millions of people, then it’s as mainstream as it gets. More people visit body modification websites than watch some tv shows, and yet we think of television as the most mainstream, monocultural thing in the world. How can you not be interested in them? They are the shape of the world to come.

[…]

Also infused in a lot of your work is what appears to me anyway to be a deep and abiding love of space travel. What is it about space that fascinates you so much?

Space is the place. We currently keep all our breeding pairs in the same place, which is kind of a stupid way to run a species. Also, it’s full of stuff we haven’t seen yet, which should be impetus enough to go and look.

What do you think about the current state of space travel, especially now with China and now private companies getting into the mix?

I find it all sadly boring. I mean, yes, the Chinese programme looks awfully promising, but it’s just re-running the prime NASA years in fast-forward — doing things we already did, all over again, in a compressed timeframe, with what is probably fairly similar technology. I’m interested to see what they do once they attain the Moon. And, again, the private stuff — Virgin is just finding a new way to replicate Alan Shepard’s sub-orbital lob. That said, Elon Musk’s projects are getting more interesting by the day. I’m starting to wonder if he doesn’t have a full-on James Bond villain long-game scheme. Wouldn’t that be great? Right up until, you know, the orbital death ray platforms.

Restore Pluto!

Filed under: Science, Space — Tags: , , , — Nicholas @ 08:01

A letter from L. Neil Smith to this week’s Libertarian Enterprise:

Here’s a matter that may reveal more about psychology or politics than it does about astronomy. You’ll recall, a couple of years ago, the flap over the “demotion” of Pluto, theretofore the tenth planet of the Solar System, to the mean and niggardly status of “dwarf planet”.

I have always believed that an international conspiracy, possibly composed of those who hate our freedom, carried out this astronomical assassination because Pluto is the only planet discovered by an American, Clyde Tombaugh.

However, given the fact that Pluto, whatever its size, is an independent body circling the same primary we do (unlike the Asteroids of the Belt or those found at various Trojan positions around the System, or parked in orbit around Mars) and the pathetic and petty way this demotion was carried out, many people, including yours truly, objected to it as unnecessary, inaccurate, and stupid.

Now we learn (because we don’t always keep up on these things) that in addition to the moon Charon, which we’ve known about for a long while, Pluto possesses four other moons, Nix, Hydra, and more recently, Styx and Kerberos, all named for various underworld-related entities in Greek mythology.

The System’s “gas giants”, Jupiter, Saturn, Neptune, and the one whose pronunciation mysteriously changes whenever it’s mentioned on TV, all have more moons than we can properly keep track of. Mars, Earth, and Venus, which are also full-blown planets in good standing, possess, respectively, two, one, and zero moons.

And yet Pluto, the little world that has been ignominiously stripped of its rank, and its sword ceremonially broken, has five moons. Count ’em: five whole moons! I maintain that this confirms its proper dignity as a first-class planet, and to the list of historic phrases like “Carthage must be destroyed!” “Remember the Alamo”, and “Hillary wears army boots!”, we should now add “Restore Pluto!”

Scientifically yours,

L. Neil Smith

Chelyabinsk meteor provides impetus for enhanced detection network

Filed under: Space — Tags: , , , — Nicholas @ 10:11

Along with all the jokes about the meteor that streaked over Siberia last week, there has been some useful re-orientation of thought about the demonstrated need for better detection tools:

For decades, scientists have been on the lookout for killer objects from outer space that could devastate the planet. But warnings that they lacked the tools to detect the most serious threats were largely ignored, even as skeptics mocked the worriers as Chicken Littles.

No more. The meteor that rattled Siberia on Friday, injuring hundreds of people and traumatizing thousands, has suddenly brought new life to efforts to deploy adequate detection tools, in particular a space telescope that would scan the solar system for dangers.

A group of young Silicon Valley entrepreneurs who helped build thriving companies like eBay, Google and Facebook has already put millions of dollars into the effort and saw Friday’s shock wave as a turning point in raising hundreds of millions more.

“Wouldn’t it be silly if we got wiped out because we weren’t looking?” said Edward Lu, a former NASA astronaut and Google executive who leads the detection effort. “This is a wake-up call from space. We’ve got to pay attention to what’s out there.”

Astronomers know of no asteroids or comets that pose a major threat to the planet. But NASA estimates that fewer than 10 percent of the big dangers have been discovered.

Want a house on the moon? Let’s just 3D print that out for you…

Filed under: Space, Technology — Tags: , , , — Nicholas @ 11:50

I’ve always wanted a house on the moon:

Architects Fosters and Partners have revealed designs for a building on the Moon that could be constructed from material already on its surface.

An inflatable structure would be transported from Earth, then covered with a shell built by 3D printers.

The printers, operated by robots, would use soil from the Moon, known as regolith, to build the layered cover.

The proposed site for the building is the southern pole of the Moon.

It is designed to house four people and could be extended, the firm said.

In 2010 a team of researchers from Washington State University found that artificial regolith containing silicon, aluminium, calcium, iron and magnesium oxide could be used by 3D printers to create solid objects.
