We were so disappointed. We were standing on the deck, watching the sky in the general direction of Wallops Island, then my wife saw the news on her smart phone that the launch had been scrubbed. I understand they will try again to launch this evening.

WAYWARD SAILBOAT SCRUBS MULTI-MILLION ANTARES LAUNCH TO ISS

JASON RHIANOCTOBER 27TH, 2014

WALLOPS FLIGHT FACILITY, Va. — The weather at NASA’s Wallops Flight Facility in Virginia – could not have been more perfect, with a 98 percent chance of favorable conditions for launch. Similarly, the Antares launch vehicle itself was primed and ready for flight. However, there will be no flight of Antares tonight - due to a sailboat. The boat drifted into the rocket’s path downrange. After attempts to contact the vessel’s occupants failed, the launch team at Wallops’ Mid-Atlantic Regional Spaceport (MARS) – were forced to call a scrub.

Just a few minutes prior to launch, at around 6:38 p.m. EDT (2238 GMT) it was announced that the launch team would remain in the built-in 12 minute hold as efforts were made to get the boat and its occupants out of the way. The Antares rocket was poised ready to fly in a south-easterly direction.

As noted, the rocket’s trajectory - would have placed it directly in the path of the sailboat – forcing a scrub in case the rocket’s flight had to be aborted – and potentially striking the sail craft.

Launch is now slated to take place no-earlier-than 6:22:38 p.m. EDT (2222 GMT) on Tuesday, Oc. 28. As with tonight’s attempt, NASA and Orbital have 10 minutes within the launch window to get the rocket and its payload off the pad – and into the evening skies.

Tonight’s delay comes on the heels of a series of other launch delays which have pushed the launch back from a planned liftoff date of Sept. 21. The most serious cause of this delay – was Hurricane Gonzalo – which struck Bermuda as a Category 2 hurricane. A tracking station, critical to monitor Antares’ flight, is located on that island, forcing a delay to determine if any damage had been inflicted because of the storm (none was).

Following this, NASA and Orbital Sciences Corporation, the manufacturer of both Antares and the SS Deke Slayton, Cygnus, spacecraft and its 5,000 lbs (2268 kilograms) of cargo set the launch date for Oct. 27.

This will mark the third operational flight of the Antares / Cygnus duo to the ISS as part of the $1.9 billion Commercial Resupply Services (CRS) contract that the Dulles, Virginia-based aerospace company has with NASA. Orbital is contracted to carry out some eight supply runs to the orbiting laboratory. Company officials expressed their displeasure about the irresponsible actions which caused tonight’s scrub.

“…a sailboat captain…a sailboat ‘operator,’ I should say, as captain implies a sense of responsibility,” said Orbital’s Vice President and General Manager Frank Culbertson.

After the scrub was declared, NASA’s Wallops Flight Facility issued the following statement:

The launch this evening was postponed because of a boat in the mariner avoidance area. While we are disappointed, as you are, public safety is paramount to us when conducting a rocket launch. Pre-determined safety rules are established and we don’t launch unless all criteria are met. Antares is now rescheduled for 6:22 p.m. EDT, Tuesday, Oct. 28.

I'd like to work out the odds of debris actually hitting a small boat in the downrange area. You'd need the rocket to fail (that's about a 2 or 3 percent chance), and not just fail but fail at the specific part of flight from shortly after clearing the pad to some time before first stage burnout- most failures occur outside this part of the flight. The failing/falling rocket has to then hit a little sailing boat in the middle of the Atlantic.

If this news story is correct, the boat was 40 miles from the launch site!

A Rocket Launch Was Delayed Monday Because Of A Boat — How Could A Boat Interfere With A Rocket?

On Monday, Oct. 27, NASA was scheduled to launch a rocket carrying a 5,050-pound cargo spaceship loaded with food and supplies for astronauts aboard the International Space Station.

But a boat got in the way. A sailboat. How can a sailboat deter a rocket?

The boat was about 40 miles from the launch site and if the rocket had taken off, it would have flown over the boat. If something had gone wrong with the rocket, say it exploded in mid-air over the boat, it could have put the boat's passengers at risk.

NASA designates a hazard zone for each rocket launch, and if there is any danger to bystanders or the rocket itself near launch time, then mission control will scrub the launch. Despite attempts by mission controllers to contact the boat, they didn't move their vessel. Because the launch window was only 10 minutes, NASA had to cancel the launch.

In preparation for the launch, NASA's Wallops Spaceflight Facility, where the launch is scheduled to take place, issued a release to local mariners outlining two danger zones. Because these boaters didn't follow these restrictions, there's a chance that the passengers on this boat could be arrested.

According to Spaceflight Now, the release states that anyone who disregarded the guidelines could be subject to fines and even arrest by the US Coast Guard and the Virginia Marine Police.

Luckily, if today's launch is successful, the cargo will still reach its destination, the International Space Station, on time.

This isn't the first time a boat has gotten in the way of a launch. In 2000, the launch of an Atlas rocket coincided with a fishing tournament and multiple boats steered into the restricted zones, so the launch was cancelled. Planes can also interfere and mission controllers must simply wait for the planes to fly clear of the rocket's path — though sometimes these launch windows are very small — just minutes — and even a responsive interloper can become a major issue and cause the launch to be rescheduled.

Boats and planes aren't the only thing that interferes with rocket launches. In August 2012, NASA postponed an Atlas V rocket due to inclement weather. And earlier this year in July, the launch of a Delta IV rocket was scrubbed four times also for inclement weather.

The launch has been rescheduled for today, Tuesday at 6:22 pm EDT. If everything goes well this evening, then most observers in the Eastern US will have the opportunity to see the rocket in the sky. NASA will begin broadcasting the event live at 5:30 pm EDT.

I am very sure that I would not like even a small bit of an exploding rocket to land on me, let alone a whole one. The terminal velocity of even a battery falling from 10 miles high would be quite fast....

The following photo was taken from the southern end of Assateague Island this past summer. The bright spot in the sky is a rocket launch from Wallops Island, approximately 5 miles from where we were standing. I am sure there is some logic behind the delineation of the safety zones, but that logic is not immediately apparent.

I guess they needn't have worried about the folks in the boat.

Unmanned NASA rocket explodes

By Greg Botelho and Dave Alsup, CNN
updated 6:36 PM EDT, Tue October 28, 2014

(CNN) -- An unmanned NASA rocket exploded early Tuesday evening.

According to NASA, the Orbital Sciences Corp.'s Antares rocket and Cygnus cargo spacecraft were set to launch at 6:22 p.m. ET. It was set to carry some 5,000 pounds of supplies and experiments to the International Space Station.

"There was failure on launch," NASA spokesman Jay Bolden said. "There was no indicated loss of life.

Bolden added, "There was significant property and vehicle damage. Mission control is trying to assess what went wrong."

I'm old enough to remember a light aircraft crashing in the Solent and wiping out a yacht and killing all the crew. It doesn't matter what the odds are. It can happen.

Apart from hitting a boat, what you described is what more or less happened.

Coincidence, or visionary powers?? :)

I seem to remember reading somewhere that the risks to boat and aircraft crews of searching the whole down range area is greater than the risk of the debris hittting a boat. NASA don't seem to mind about re-entry capsules landing in the ocean.
