ISS: Russian Progress 59 Lost in Space

Tuesday's International Space Station Russian resupply spacecraft, Progress 59, started spinning out of control after separating from its Soyuz rocket.  The resupply mission has now been written off as a failure, which is the second in a year after the Antares rocket explosion last October (blamed on an old Soviet rocket).

Fortunately, SpaceX's Dragon resupplied the station earlier this month and will return in June with more supplies. Redundancy, and private ventures, to the rescue.

Update: Progress 59 is expected to reenter to atmosphere and burn up in the next two weeks.

Does Ukraine Still Have a Space Industry?

Last week I read a piece in Parabolic Arc stating the Ukrainian space industry was close to collapsing. The article relates to Yazhmash, the rocket manufacturer and cornerstone of the Ukrainian space industry, and its recent notice about problems with orders from the Russians.  The article quotes the company's press release:
Yuzhmash
Yuzhmash
Factor of negative trends – landslide production cutbacks due to rupture of ties with traditional customers, who provided most of the orders.

The actual bankruptcy of the enterprise will result in the loss of Ukraine’s status as a space power, failure of the obligations of the State to enter into international agreements, irreversible loss of proven technologies.
At present, the SE “PA YuMZ behalf AM Makarov” is a participant in the high-tech large-scale international projects: "Sea Launch","Land Launch", "Taurus II / Antares", "Dnepr","Cyclone-4", "Vega". 
For instance, Orbital Science's uses the Antares rocket that was built in cooperation with Yazhmash.

Russian has been threatening for some time to find substitutes for the Ukrainian rocket parts, with the Moscow Times noting:
Russia's dependence on Ukrainian defense imports is a by-product of the collapse of the former Soviet Union. When the Ukrainian Soviet Socialist Republic became an independent state in 1991, Kiev found itself in possession of vital Soviet-era defense industry assets such as the Yuzhmash factory in Eastern Ukraine, which produces space rockets, satellites and missiles along with machinery for civilian uses.
Bloomberg Business highlighted the company's plight, stating:
Sales to Russia plummeted from $1.7 billion in 2011 to only $28 million last year, Yuzhmash said in a statement posted on its website last month. The Dnepropetrovsk-based company owes some $140 million in back wages to its 15,000 workers and partially suspended manufacturing operations until late February. The company did not respond to calls from Bloomberg Business.
Russia has already caused enough problems for Ukraine, and now this.  Maybe the US government can find a way to bring Ukraine into its military and civilian space industry while continuing to exclude the Russians.

More on the Orbital Sciences Mishap

To date most of the stories on the Orbital Sciences' explosion last month placed blame on the Soviet-era engines in the Antares rocket.  CEO David Thompson recently noted, "Current evidence strongly suggest that one of the two AJ26 main engines that powered Antares' first stage failed about 15 seconds after ignition."   

Forbes magazine provided more information on these Russian rockets:

The rocket’s two engines were modified Soviet-era hardware initially acquired from Russia in the late 1990s by the now defunct Kirkland, Wa.-based Kistler Aerospace Corporation. At the time, prior to its merger with Rocketdyne, the Sacramento, Ca.-based Aerojet Corporation had been subcontracted by Kistler to modernize the engines. However, Aerojet subsequently gained title to the engines as part of Kistler’s bankruptcy settlement.  “They were originally developed by the Soviet Union for their N-1 manned lunar rocket which experienced several failures resulting in the Soviet cancellation of their manned lunar landing program,” said Bill Ketchum, a retired General Dynamics Corporation aerospace engineer, familiar with such systems.
So Orbital Sciences used engines from the 1970s, which were associated with a failed Soviet lunar mission, as the foundation for their work with NASA?  Was anyone watching the hen house?  I prefer SpaceX's approach of building everything in-house.  I would prefer NASA and the Air Force would do the same rather than also relying on Russian rockets.  

On November 5th, Orbital Sciences restated it intentions to fulfill the International Space Station (ISS) commitment:

Under the new approach and in line with Orbital’s existing CRS contract, all remaining cargo will be delivered to the International Space Station (ISS) by the end of 2016. There will be no cost increase to NASA and only minor adjustments will be needed to the cargo manifest in the near term...To maintain the CRS program’s critical ISS supply line, Orbital plans an early introduction of its previously selected Antares propulsion system upgrade in 2016. This will be preceded by one or two non-Antares launches of the company’s Cygnus cargo spacecraft to the ISS in 2015-2016, employing the spacecraft’s compatibility with various launch vehicles and its flexibility to accommodate heavier cargo loads as launcher capacity permits. In addition, the company expects repairs to the Mid-Atlantic Regional Spaceport (MARS) launch complex at NASA’s Wallops Flight Facility to be undertaken quickly, allowing launch operations to continue at Wallops Island with the upgraded Antares beginning in 2016.
In other words, the program will continue, but the Cygnus cargo capsule will be carried on third-party rockets for now.  Maybe SpaceX Falcons?  This is not a very encouraging sign, but hopefully a short-term solution for one of the only two private sector suppliers for the ISS.

Disaster Strikes Orbital Sciences' Rocket

Orbital Sciences' third resupply mission to the International Space Station ended in disaster earlier today as the rocket exploded shortly after liftoff in Virginia. Fortunately, the mission was only carrying cargo and not astronauts. Expect an extensive inquiry.  Stay tuned.

Update: I corrected my posting to note this was Orbital Science's third planned mission to the ISS. In terms of the accident, the company's website stated:
Orbital Sciences Corporation confirms that today’s Antares rocket launch from NASA’s Wallops Flight Facility was not successful. Shortly after lift-off from the Mid-Atlantic Regional Spaceport Pad 0A at 6:22 p.m. (EDT), the vehicle suffered a catastrophic failure. According to NASA’s emergency operations officials, there were no casualties and property damage was limited to the south end of Wallops Island. Orbital has formed an anomaly investigation board, which will work in close coordination with all appropriate government agencies, to determine the cause of today’s mishap.
This may mean more work for SpaceX to pick up the slack.
