PYONGYANG, North Korea — The long-awaited launch of North Korea's Kwangmyongsong-3 satellite has finally happened — and apparently has ended in failure. Now what?
Even before Friday's liftoff, failure seemed like the most likely option. The things that I saw this week during our amazing insider tour of the North Korean space program made me even more doubtful that the Earth-observing satellite would be successfully placed in orbit.
The fallout from a mission failure could follow any of several possible scenarios. A lot depends on the circumstances surrounding the failure.
One of the most straightforward scenarios would involve an explosion just after liftoff from North Korea's new Sohae launch base . This may not be as easily detectable as it sounds, especially since the video transmission from the launch site has been tape-delayed. In that case, "no news" is all the news there will be, until a later announcement that the launch was "indefinitely postponed."

Local residents north of the base — and we saw lots of villages there — would notice the explosion, but might not even connect it with a rocket. And rumors would be unlikely to spread very fast in such a tightly controlled society.
After a minute or so of flight, the rocket will be high in the skies over the western half of the country, including the capital, Pyongyang. Any "energetic event" (NASA’s favorite euphemism for a bad-ass explosion) would streak the sky with a burst of flame — but no sound.
Lots of people would see it, and some foreign visitors might even get a picture. But these photographs and videos would be recognized for what they showed only if the launch was announced within a minute of liftoff.
Another opportunity for failure could have come after a well-publicized liftoff, after the vehicle vanished over the southern horizon. The critical third-stage burn, which apparently involves a fairly sophisticated sideways jog to slip into the proper final orbit, would be too far away for in-country tracking sites to receive signals.
The wait for confirmation would be excruciating, because the satellite’s orbit is not projected to pass within radio range of North Korea for 11 hours. This is a real situation — I’ve checked the orbital flight path myself — and it’s caused by the steep polar orbit of the vehicle.
'Space is hard'
Failures in space often occur because, basically, "space is hard." And it’s especially hard on beginners. Failure rates in almost every national program start out high, and then diminish.
But people can also make spaceflight harder than it has to be through careless and imprudent attitudes. These can interfere with the crucial process of error detection, diagnosis and correction, that must occur effectively many times a day in the run-up to a space shot.

If people are pressured into cutting corners and taking shortcuts to meet an unrealistic schedule, critical choices may be overlooked, crucial repairs may be omitted. Lamentable examples from the past are too numerous and well-known to merit mentioning.
The schedule pressure on this North Korean mission, tied to the most important holiday in their country’s history, must have been immense. It’s a formula for fatal errors, all too familiar to space experts.
The North Korean situation was made worse by the "launch fever" attitude exemplified by mission managers in front of visiting Western journalists. With quasi-religious fervor and dedication to an ideology they treat as near-divine, their ability to tolerate dissent or doubts from working troops must have been very, very low. When in doubt, it seems, they quote favorite passages from their leaders’ writings, and charge ahead.
This is more than worrisome: It seems to be a recipe for disaster. Every worker must have the courage to speak up and recommend remedial measures. Whether they can overcome this culture in a technological field that is notoriously intolerant of make-believe is the most serious issue I found on my visit.
There are a wide variety of excuses available to all observers to "explain away" a failure. And since rocket scientists know that the first step towards one’s next disaster is to forget about — or deny — the previous disaster, the North Korean insistence against all evidence that their first two satellites were actually successful, is not auspicious.
The first and most traditional reaction from Pyongyang to a satellite failure would be simply to pretend it succeeded. That worked for them in 1998 and 2009, but this time there is too much scrutiny from visitors and worldwide radio amateurs to make such a pretense attractive.
The next choice, however, is worse: Blame foreign enemies. If the failure occurred early in flight, the South Koreans can be implicated. If it occurred farther away, out of radio contact, U.S. malevolence is an obvious scapegoat. This is an instinct that we even saw in some supposedly sensible Russian space experts when their recent Mars probe tripped on its face just out of the starting gate. U.S. radar interference was widely suggested as the cause, a gimmick that North Korea could be expected to copy for its own needs.
Alternately, Pyongyang could blame internal enemies intent on sabotage, an old Stalin-era trick. It could help fuel a major purge of less-than-perfectly-loyal officials during the ongoing regime transition. Hundreds could be fired, and many shot — a convenient excuse for a housecleaning.
Russia came up with a less malicious blame-shifting gambit recently when they officially explained the crash of the Mars-bound Phobos-Grunt probe on what today passes for an "act of God" — space radiation. Supposedly, two computer chips were zapped by cosmic forces beyond the control of mere earthlings. If the North Koreans are feeling unusually benign, they could opt for this excuse, and reduce the need for much bloodletting.
Western conspiracy theory
No catalog of conspiracy theories would be complete without a version that might spring up in the West — that the failure was all part of a preordained plan to hide a top-secret weapons test. Like all good conspiracy theories, it originates from a web of actual facts, but then lets the imagination guide the conclusions.
Here’s one version: the "satellite" was never on board, but had been surreptitiously replaced by the one major missile weapon component not yet verified, a heat-shielded re-entry capsule. Until this technology is acquired, the ability to throw a warhead thousands of miles is useless, because the descending warhead would burn up as soon as it hits the atmosphere.
So to close this gap, put a test warhead under the nose cone. Launch it as a "satellite." Let the warhead drop back into the atmosphere along with the spent second stage, where it can radio simple test results to a small ship or submarine. Physical recovery wouldn’t be necessary to confirm that the design worked.
All these excuses have the virtue of being simple and easy to understand. Their only drawback, aside from the aggravation of already-too-high tensions in the area, is that they would be wrong — and worse than useless in preparing for a new launch attempt.

NBC News space analyst James Oberg spent 22 years at NASA's Johnson Space Center as a Mission Control operator and an orbital designer. He is the author of several books on space history and space policy, including "Star-Crossed Orbits: Inside the U.S.-Russian Space Alliance."
Oberg's initial report from Pyongyang was filed prior to launch, and updated to reflect reports after the launch.
