    The International Space Station should be visible tonight over the DC region, depending on cloud cover. According to NASA’s Spot the Station website, the ISS should be visible over the DC area from 7:03 to 7:09 pm. Sunset is at 6:12 pm and the forecast is for partly cloudy skies. At max height, it will appear 83* above the horizon. It will appear to travel from 10* above NW to 12* above SE.

    The European resupply vehicle, Albert Einstein ATV4, should also be visible, just a few minutes before the ISS comes into view. It will appear along the same path, NW to SE.

    Unlike in the movie “Gravity”, the two objects are not expected to smash into each other.

    Even though no one died, it’s still stunning and even saddening. One civilian said that she felt the blast of the explosion from 5 miles away.

    Orbital Sciences stock took a hit last night, but they have been very accessible and open with updates on the launch and the “catastrophic anomaly.” NASA said they remain confident in Orbital Sciences and their ability to resupply the ISS in the future, once they determine what went wrong this time. They are based in Dulles (Sterling). It’s disappointing to see a local Northern Virginia company fail, but I think they will get back on their feet.

    I don’t know how long it will take to repair any damage to the launch pad. Isn’t it mostly concrete plus the tower and some utility lines?

    It took 2 years to build it in the first place. There are a lot of lines: the water for the suppression system, the comms, the fueling system, etc. Then it’s got to mate to the rocket. If the concrete were cracked or heat damaged significantly it may be easier to tear it down for rebuild than to fix it. In the old days they would have built two, but I guess the logic was that there was enough redundancy was in the form of the launches from KSC that they didn’t need redundancy at WFF. They may reevaluate that at this point; there’s room for another pad, it’s just a money issue.

    Unless you want to bomb brown people near oilfields… in which case $ is no object. :-

    There already is a second launch pad at Wallops, although it is designed for the Minotaur rocket and similar vehicles. MARS Pad 0B is licensed for payloads up to 8400 lbs. The damaged MARS pad 0A is licensed for payloads up to 11,100 lbs. [MARS stands for Mid-Atlantic Regional Spaceport.]

    The LADEE unmanned lunar mission last year launched from Pad 0B.

    The next scheduled Cygnus mission (Antares rocket using Pad 0A) was planned for January 2015, but it’s unlikely to take place at that time.

    Yesterday’s mission included 5,000 lbs. of cargo, which is within the allowed range for Pad 0B, but I don’t think that pad is certified for the Antares rocket.

    I meant a second Antares pad. It’s not just the payload weight rating that matters (though that does require some engineering since it’s built on a sandbar) but also the physical interface to the rocket and transporter. AFAIK it isn’t possible to launch the Antares from 0B without rebuilding that pad.

    The damage doesn’t look nearly as severe as it might have been, according to photos posted today by NASA:

    I’m no damage expert, but clearly the water tower is still intact. This is the official post from the NASA Wallops Flight Facility today:

    The Wallops Incident Response Team completed today an initial assessment of Wallops Island, Virginia, following the catastrophic failure of Orbital Science Corp.’s Antares rocket shortly after liftoff at 6:22 p.m. EDT Tuesday, Oct. 28, from Pad 0A of the Mid-Atlantic Regional Spaceport at NASA’s Wallops Flight Facility in Virginia.

    “I want to praise the launch team, range safety, all of our emergency responders and those who provided mutual aid and support on a highly-professional response that ensured the safety of our most important resource — our people,” said Bill Wrobel, Wallops director. “In the coming days and weeks ahead, we’ll continue to assess the damage on the island and begin the process of moving forward to restore our space launch capabilities. There’s no doubt in my mind that we will rebound stronger than ever.”

    The initial assessment is a cursory look; it will take many more weeks to further understand and analyze the full extent of the effects of the event. A number of support buildings in the immediate area have broken windows and imploded doors. A sounding rocket launcher adjacent to the pad, and buildings nearest the pad, suffered the most severe damage.

    At Pad 0A the initial assessment showed damage to the transporter erector launcher and lightning suppression rods, as well as debris around the pad.

    The Wallops team also met with a group of state and local officials, including the Virginia Department of Environmental Quality, the Virginia Department of Emergency Management, the Virginia Marine Police, and the U.S. Coast Guard.

    The Wallops environmental team also is conducting assessments at the site. Preliminary observations are that the environmental effects of the launch failure were largely contained within the southern third of Wallops Island, in the area immediately adjacent to the pad. Immediately after the incident, the Wallops’ industrial hygienist collected air samples at the Wallops mainland area, the Highway 175 causeway, and on Chincoteague Island. No hazardous substances were detected at the sampled locations. Additional air, soil and water samples will be collected from the incident area as well as at control sites for comparative analysis.

    The Coast Guard and Virginia Marine Resources Commission reported today they have not observed any obvious signs of water pollution, such as oil sheens. Furthermore, initial assessments have not revealed any obvious impacts to fish or wildlife resources. The Incident Response Team continues to monitor and assess.

    Following the initial assessment, the response team will open the area of Wallops Island, north of the island flagpole opposite of the launch pad location, to allow the U.S. Navy to return back to work.

    Anyone who finds debris or damage to their property in the vicinity of the launch mishap is cautioned to stay away from it and call the Incident Response Team at 757-824-1295.

    Further updates on the situation and the progress of the ongoing investigation will be available at http://www.orbital.com/ and http://www.nasa.gov/orbital
