Blinded by the Light

by Chris Krupiarz

This article originally appeared in this week's issue of ​The Magazine​, an ad-free, subscriber-supported fortnightly periodical of medium-length feature reporting and essays.

The probe sails through space, traveling the distance of the LA-to-Chicago red-eye in a minute. My fellow engineers and scientists who built the spacecraft are now some 99 million miles distant on a blue-tinged point of light. We call the probe Messenger.

This name identifies its scientific mission — MESSENGER stands for MErcury Surface, Space ENvironment, GEochemistry, and Ranging — and acknowledges its destination’s eponym, the Roman god of communication and much more. Operating beyond Earth’s atmosphere and without an engineering requirement for beauty, the spacecraft lacks the smooth lines of a Newey-designed F1 car slicing through the Mediterranean air of Monaco, or the splendor of Strauss’s Golden Gate Bridge against a gloomy June sky in San Francisco.

Messenger instead resembles a Lego model of non-descript blocks connected by a subway map of wires and cables. The spacecraft is designed for a singular purpose: to be the first probe to orbit Mercury.

We sent Messenger on its way August 3, 2004. Until Messenger completes its mission, the spacecraft is vulnerable to its surroundings. One bump along its journey remains a vivid reminder.

Deep space none

Traveling with Messenger to the planet closest to the Sun would have been a nightmare vacation. The trip takes years and then the weather on arrival is Phoenix-hot or McMurdo-cold, only far more severe.

For the craft, Mercury’s heat is a bigger problem than the cold. Messenger’s survival depends on an eight-foot by six-and-a-half-foot sunshade providing an SPF in the hundreds of thousands to protect against 700° F temperatures. The sun’s rays will eventually scorch the shade’s white ceramic-cloth surface to burnt-toast black, while behind the shield it stays room temperature.

The project scientists’ stand-ins hide within the shade: a suite of instruments ranging from the imager — the glamour photographer whose prints will grace the covers of Science and Discover — to the introvert of the group, the magnetometer. The magnetometer must stand apart from the crowd, attached to the end of a 12-foot boom, thus avoiding the chatter of the spacecraft’s own magnetic field. Twin solar panels bring electricity to the party; mirrors cover the panels to limit temperatures to a roast-ready 300° F.

During lulls in its internal chatter, Messenger sends instrument and spacecraft data to the three Deep Space Network stations on Earth: one over the hill from the Murrumbidgee River near Canberra, another just off of Calle Blas de Otero in the mountains west of Madrid, and the third in middle-of-nowhere California, northeast on the I-15 from LA.

When Messenger lifted off from Cape Canaveral in 2004, it was a rhino’s weight, with much of its heft from fuel. It has been on a diet since, losing mass each time a thruster burps puffs of skin-burning hydrazine or the main engine fires to change course. An on-board computer directs these actions and others via a shopping list of commands sent from Earth. The cost and the limits of physics in fighting the harsh environment of space has slowed space processor evolution — the latest iPhone runs nearly 100 times faster than the Messenger computer.

I know that computer well: I’m responsible for the flight software that’s controlling the spacecraft during this mission phase. And as I sit in my office at that moment, I hope that computer is still in one piece. I just received an email from Eric Finnegan, who, in his role as the Messenger mission systems engineer, is the leader of the spacecraft team. He has sent this message to all the team members:

Subject: MSGR: Spontaneous Loss of Signal today during DSS-63 All, Andy just informed me that we lost signal from Messenger today during the DSS-63 contact. They are tracing the ground system now. I am heading over to the MOC to get more situational awareness. Please join me as soon as possible. -ejf-

From the email, I know that Messenger had been talking with one of the Deep Space Network stations in Madrid, designated DSS-63. These periods of communication, called passes, are typically the length of a workday, about eight hours. Somewhere in the middle of that pass, Messenger had gone silent. Unless commanded to be quiet, spacecraft do not stop chatting: they constantly blabber like one of my sons after his first day of school. Eric calls us all to the mission operations center. Something is wrong.

I send my wife an email that begins, “It’s going to a long day…” and start to pack my computer bag for the walk to mission operations. Just before I shut down my laptop, I receive one last email, this one from those at the Deep Space Network:

FLASH 1: Messenger in Spacecraft Emergency Initial Incident Report: On DOY 244/1633z, the Messenger Project declared Spacecraft Emergency. They stated lost contact with the spacecraft at 142640z.

We need to find out what happened.

Scrimmage

This isn’t my first rodeo. The first spacecraft I worked on failed upon launch; the second failed in orbit. I don’t need a third strike. But at my workplace, the Johns Hopkins University Applied Physics Laboratory (APL), I’m surrounded by scientists and engineers who devote themselves to figuring out hard problems. As I descend the stairs on my way out of my home base, Building 7, I pass a sign that reminds me of our wonkiness and precision: “Down to First Floor for Exit Discharge.”

Deep space missions are marathons. The mission team, led by the principal investigator from the Carnegie Institution of Washington, Sean Solomon, twice proposed the mission to NASA before it was accepted. Once approved, Messenger took four years to build, and at the time I take this walk, it has two years left on its trip to Mercury.

On arriving at Building 13, which houses the mission control center, I swipe my badge on the security reader and enter. Along the stem of the L-shaped room sit computer terminals for the instrument teams, as well as the propulsion, power, navigation, communication, and flight software subsystems. In the front of the room, what would be the base of the L, sit autonomy, guidance and control, the mission systems engineer, the mission operations manager, and the flight controllers. Off to the side is a room with glass walls, where, during significant events, upper management nervously waits to see whether the next day’s press release will be a positive one.

Standing near the flight controllers, staring at dual data screens on the wall, are Eric Finnegan and Andy Calloway. Eric is lean and energetic, with dark hair, dark eyes, and a perpetual five-o’clock shadow. He is wearing a white shirt and tie and has his ever-present Blackberry on his belt. Andy, the head of operations, is compact and tennis-player fit. An APL security badge hangs around his neck and he is wearing a polo shirt and jeans — the closest that Lab employees come to a uniform.

“What’s the status?” I ask.

“We lost contact about 45 minutes ago,” says Andy. “We were loading a series of macros to EEPROM when the signal just vanished.”

EEPROM is a predecessor to the flash storage used in SD camera cards. As with flash memory, EEPROM data remains permanent once written, even without power. Macros are a series of commands designed to be executed in sequence. There’s a clue in there, but I need more information.

“Were we doing compression? Downlinking files? Collecting images?”

“No,” replies Andy.

This is a good sign. Those three software functions have caused issues in the past. I thank Andy for the information and then sit down next to Adrian Hill, the autonomy lead for Messenger and a calming influence on the team. He is also an NFL on-field official. Perhaps having Bill Belichick yelling in his ear builds antibodies for stress.

I ask Adrian, “They weren’t doing much other than loading macros to memory. Could it be a multi-bit error?”

Adrian says he was thinking the same thing. Space is unkind to electronics. The sun, distant supernovae, and other sources launch particles that drill through these components. These subatomic bullets may damage computer memory by flipping a bit from a one to a zero or vice versa.1 Engineers have added a little math to computer memory that can automatically flip the bit back to the proper value.

However, if this happens more than once in a single computer word (the numbers of bits that a processor uses as its native basic unit), we call it a multi-bit error: the computer is not smart enough to determine which of the bits have flipped. To avoid reading corrupted data and making a bad decision, the computer reboots itself. This is an annoyance, but the computer would be doing what it is designed to do to fix the problem.

Seeking truth

We tell Eric and Andy our theory, although I am initially hesitant. Experience has shown that the more positive I am that I am right, the more likely it is I am wrong. I add the caveat that we will not know for sure until the spacecraft starts talking again.

I head across the room to my computer station. Already there at the adjoining terminal is the communication lead, Karl Fielhauer. A gray-haired, gregarious man, Karl is the type of guy that quickly lets you know where he stands. When I arrived in the mission operations center during a previous emergency, he summarized the situation with a succinct “we’re screwed.”

Today the conversation quickly diverts to our favorite subject: the Detroit Tigers. Despite the team being three and a half games up on the Twins and in first place in the American League Central, we still complain. We are both from Michigan and are lifelong Tiger fans; history dictates that a season implosion is likely just a few bizarre plays away.

Karl is relaxed because he has looked at his data and noticed that the signal from Messenger did not immediately drop away. Instead, it had slowly lost strength. Andy, Eric, and Karl conclude that Messenger is probably looking for us, like a child lost in the forest calling out for Mom and Dad.

Most spacecraft have multiple modes; we like to see Messenger in operational mode. That means the spacecraft is happily collecting data and all systems are working fine. Instead, Messenger may be in Earth-acquisition mode. The spacecraft would still be alive, slowly rotating to scan the sky while calling to its family on Earth. If that’s true, Messenger will take about three hours to rotate once and find us.

I log in to my terminal and send an email to Annette Mirantes, a colleague on the software team who recently moved overseas. For her, it is late afternoon in Gijón on the Bay of Biscay in northern Spain. Despite supposedly knowing much about computers, I find it magic that I can type on a laptop in Maryland and have that information almost immediately show up on the screen in Annette’s house in Europe. I summarize the situation and we determine what to examine once we get data back from Messenger. Annette replies:

If it's a multi bit error, we'll see it in 406: HSK_MULTIBIT_ERR_TT will be TRUE HSK_MEM_MULTI_BIT_ERR_CNT will be > 0 

Annette is referring to data packet 406 and two data points within. A packet is like an envelope. Inside the envelope is a list of data points and their current values. Data packets are grouped in a spacecraft version of the Dewey Decimal System. The 400 to 499 range is spacecraft data; the 406 packet contains diagnostic data. If the data point HSK_MULTIBIT_ERR_TT is true, it will confirm our theory of a multi-bit error. This will still require a spacecraft recovery, but I can head home and monitor the data from there. If the value is false, I will soon wish mission operations had extra cots.

Spinning round and round

As the three-hour mark approaches, the chatter in the operations center stops. We gather at the front of the room to watch a screen showing a graph that looks like an EKG. The display represents the signal strength from Messenger. The signal remains flatlined at zero until, slowly, the values begin to inch up. The spacecraft is alive, but we do not know how sick it is.

The next step is to tell the spacecraft to stop rotating. To do this, mission operations must command the spacecraft at the precise moment on a subsequent rotation that it again comes into view of the Deep Space Network antennas. Performing this operation is like timing the windmill shot at the Rocky Gorge mini-golf course, except at a distance of 99 million miles.

But, given the skill of the mission operations team, they make the putt and we eventually see a steady stream of communication from Messenger. The data values we need are screaming through space at the speed of light, but at this distance they take eight minutes to arrive.

Andy calls out, “DSN reports the first frame is in. You should be seeing data in about 12 minutes.”

The additional delay is due to the downlink rate. Because Messenger is in an emergency mode, the spacecraft is sending data at only 10 bits per second, a millionth the rate of home broadband.

“We have a 406 packet in the pipeline,” says Andy. That is the packet we need.

I wait. The spacecraft data points are displayed purple, indicating that the information is the same we saw many hours ago. Once they switch to green, I will know we have new data. I eye the screen. The key data point I am watching goes green.

HSK_MULTIBIT_ERR_TT = TRUE 

It is a multi-bit error.

I email my wife: “I’ll be home for dinner.”

Messenger arrived safely in orbit on St. Patrick’s Day, 2011. Since then, the spacecraft has sent back the first complete map of Mercury, confirmed water ice in shadowed craters, and discovered an abundance of sulfur on the surface. Once Messenger’s fuel is depleted, Mercury’s gravity will slowly disrupt the probe’s orbit, lowering the spacecraft until it eventually hits the planet.

  1. A bit flip was in the news twice in recent years. First, when Voyager 2 in 2010 had its flight data system computer experience such a switch; engineers were able to fix that. In March 2013, Curiosity had a glitch that may have been caused by cosmic radiation. Redundancy in computers is a key to recovery.

Why Do Chinese Tourists Have Such A Bad Rep? Ctd

by Chris Bodenner
by Chris Bodenner

Readers can relate to a recent post:

One of my vivid memories of traveling in Tibet in 2006 is from visiting one of the monasteries in Lhasa to see the monks debate one another. Dozens of them gathered in a courtyard criss-crossed with stone paths to take part in these lively sessions. It was a unique and wonderful experience, but the Chinese tourists who attended were the one black mark. They treated the place like a zoo and the monks like animals. While almost everyone stayed on the stone paths and kept a respectful distance watching the monks debate and snapping the occasional photo, the Chinese tourists would walk straight up to the monks and stick a camera literally inches from their faces. It was jarring to watch them do it, and obviously the history and ongoing tension between China and Tibet colors the dynamic even more.

Another:

As you can tell from my VFYW and airplane window photos you’ve published, I get around. And little irritates me more while traveling than Chinese tourists.

I enjoy hiking, but don’t expect to see any wildlife when Chinese tourists are around. They block trails by not letting anyone pass, speak at their loudest, don’t respect personal space and just drive every living thing away from their vicinity. As you can imagine, bus loads are the worst, and the Chinese tour guides don’t do anything to take control of the chaos, as they’re often just as bad as their charges right to the point of using bullhorns.

The main reason I’m writing is to share an amusing experience with a Chinese couple while traveling in Australia. On a flight from Sydney to Adelaide a married couple, probably in their mid-fifties, obviously clueless about air travel, was driving the flight cabin crew crazy with their mild panic about every little thing, with the language barrier only making the situation worse (they didn’t speak one word of English and there was no one on the plane who could translate). We were relieved to be landing so we could be rid of them, but as we were descending, wheels down, runway dead ahead, everyone including the cabin crew strapped into their seats, suddenly the Chinese woman decided it was time to use the bathroom! A female cabin crew member unbuckled herself, bolted down the aisle, grabbed the woman from behind, threw her into her seat and buckled her in, then made it back to her own seat just in time for touchdown.

That was entertaining, but we weren’t through with them yet!

Adelaide has a small airport and an equally small luggage carousel. The Chinese couple pushed their way in front of the waiting passengers to the luggage exit and began pulling every black bag off the carousel in what appeared to be a panic as they looked for their own. Soon there was a small pile of black luggage as they were tripping over themselves trying to pull more off while throwing some of the bags back on after they confirmed, with much nervous discussion between themselves, that each rejected bag was not theirs. At one point the Chinese man even fell to one knee onto the carousel, so I was expecting a recreation of the Ab Fab episode where Patsy was riding it! The waiting passengers were dumbstruck. No one knew what to do or wanted to get too close, so I finally announced I’d go get a member of airport security to take charge.

That’s when I heard “They are my parents!” I turned and saw a young Chinese man in his early twenties, just standing there and watching the spectacle. I realized he had arrived at the airport to pick up the couple, so I blurted out “Help them!” He seemed offended and replied “They never travel before!” We had words about his responsibility to help his parents, so the older couple finally settled down and retrieved their bags with their son’s help. Knowing East Asian cultures, younger people are often hard-pressed to correct or give direction to members of their older generation, even when they’re making a scene.

It turns out Adelaide has several universities that attract large numbers of Chinese students, so we surmised this couple was making a visit to their son, possibly their first time outside of China. Hopefully he gave them some instructions for making it home without any calamities.

Another:

My husband and I were in Paris last February and did a tour of Versailles. We lucked out in that we were the only English speakers that morning and had an English-speaking tour guide to ourselves. Over the course of three hours, we were jostled from room to room and throughout the grounds, fighting for space among the bus-loads of Chinese tourists. Towards the end of the tour, our snobby French tour guide, who never seemed to thaw towards us, turned to us and said “I can’t believe I’m going to say this but Chinese tourists make me long for the days when Versailles was overrun by Americans.”

The Value of a CEO

by Alex Tabarrok

Steven Ballmer announced today that he would retire. Microsoft stock shot up immediately by ~$2.18 or 6-7%. Given 8.33 billion shares outstanding that’s an increase in value of about $18 billion dollars. Of course that’s embarrassing for Ballmer but the lesson cuts both ways. If Ballmer’s exit and replacement with an unknown is worth $18 billion then hiring the right CEO at $27 million annually, the average annual pay for the 100 highest paid CEOs in America, looks like a bargain. Small differences are a big deal for large corporations, you know like a marginal… something or other.

Ballmer Retirement

11 Untranslatable Words From Other Cultures

by Ella Sanders
The relationship between words and their meaning is a fascinating one, and linguists have spent countless years deconstructing it, taking it apart letter by letter, and trying to figure out why there are so many feelings and ideas that we cannot even put words to, and that our languages cannot identify. Visit Maptia for more interesting posts.

The idea that words cannot always say everything has been written about extensively – as Friedrich Nietzsche said:

Words are but symbols for the relations of things to one another and to us; nowhere do they touch upon the absolute truth.

No doubt the best book we’ve read that covers the subject is ‘Through The Language Glass‘ by Guy Deutscher, which goes a long way to explaining and understanding these loopholes – the gaps which mean there are leftover words without translations, and concepts that cannot be properly explained across cultures.

Somehow narrowing it down to just a handful, we’ve illustrated 11 of these wonderful, untranslatable, if slightly elusive, words. We will definitely be trying to incorporate a few of them into our everyday conversations, and hope that you enjoy recognising a feeling or two of your own among them.

1. German: Waldeinsamkeit

1-web

A feeling of solitude, being alone in the woods and a connectedness to nature. Ralph Waldo Emerson even wrote a whole poem about it.

2. Italian: Culaccino

2-web

The mark left on a table by a cold glass. Who knew condensation could sound so poetic.

3. Inuit: Iktsuarpok

3-web

The feeling of anticipation that leads you to go outside and check if anyone is coming, and probably also indicates an element of impatience.

4. Japanese: Komorebi

4-web

This is the word the Japanese have for when sunlight filters through the trees – the interplay between the light and the leaves.

5. Russian: Pochemuchka

5-web

Someone who asks a lot of questions. In fact, probably too many questions. We all know a few of these.

6. Spanish: Sobremesa

6-web

Spaniards tend to be a sociable bunch, and this word describes the period of time after a meal when you have food-induced conversations with the people you have shared the meal with.

7. Indonesian: Jayus

7-web

Their slang for someone who tells a joke so badly, that is so unfunny you cannot help but laugh out loud.

8. Hawaiian: Pana Poʻo

8-web

You know when you forget where you’ve put the keys, and you scratch your head because it somehow seems to help your remember? This is the word for it.

9. French: Dépaysement

9-web

The feeling that comes from not being in one’s home country – of being a foreigner, or an immigrant, of being somewhat displaced from your origin.

10. Urdu: Goya

10-web

Urdu is the national language of Pakistan, but is also an official language in 5 of the Indian states. This particular Urdu word conveys a contemplative ‘as-if’ that nonetheless feels like reality, and describes the suspension of disbelief that can occur, often through good storytelling.

11. Swedish: Mångata

11-web

The word for the glimmering, roadlike reflection that the moon creates on water. TC mark

Researchers Release Tool That Can Scan the Entire Internet In Under an Hour

by samzenpus
dstates writes "A team of researchers at the University of Michigan has released Zmap, a tool that allows an ordinary server to scan every address on the Internet in just 45 minutes. This is a task that used to take months, but now is accessible to anyone with a fast internet connection. In their announcement Friday , at the Usenix security conference in Washington they provide interesting examples tracking HTTPS deployment over time, the effects of Hurricane Sandy on Internet infrastructure, but also rapid identification of vulnerable hosts for security exploits. A Washington Post Blog discussing the work shows examples of the rate with which of computers on the Internet have been patched to fix Universal Plug and Play, 'Debian weak key' and 'factorable RSA keys' vulnerabilities. Unfortunately, in each case it takes years to deploy patches and in the case of UPnP devices, they found 2.56 million (16.7 percent) devices on the Internet had not yet upgraded years after the vulnerability had been described."
