Birds of a feather: A European Space Agency (ESA) working group has recommended the agency focus its next manned space project on redesigning its now abandoned ATV cargo ship as a service module for the U.S.’s Orion capsule.

Believe it or not, this is how ESA plans to pay for its use of ISS from 2017 to 2020, by abandoning the ATV (which supplies ISS) and building a service module for a capsule that might never launch and is not intended to go to ISS anyway.

But then, it isn’t surprising, coming from a government agency.

ATK’s push to build its Liberty launch system.

9:17 am

The competition heats up: ATK’s push to build its Liberty launch system.

Liberty was one of the suitors [for NASA’s commercial crew] funding, before losing out to the four aforementioned options during the selection process. However, ATK decided to press on with the development of the system under an unfunded Space Act Agreement (SAA), with a clear intent of convincing NASA they deserve to be awarded funding for the path towards crewed launches.

Indeed, ATK have stated that they will continue with the development of Liberty regardless of NASA funding, as much as Agency support would provide an accelerated schedule towards bringing the vehicle into operation by 2015. [emphasis mine]

If you read the article, you will see that there are many reasons why I would rather NASA did not pick ATK. The system depends too much on the shuttle’s legacy at the Kennedy Space Center (the VAB, crawler, etc), which means it will probably require a large labor force to launch and thus be expensive. However, if ATK can make Liberty profitable without NASA, I am all for them.

Boeing and Lockheed Martin are both considering hiring the Russia aerospace company Energia to build components for the CST-100 and Orion manned capsules.

9:01 am

It appears that both Boeing and Lockheed Martin are considering hiring the Russia aerospace company Energia to build components for the CST-100 and Orion manned capsules.

What is going on here is that both Boeing and Lockheed Martin are looking for a subcontractor who can build these components for less money. Since labor costs in Russia are much lower than the U.S., both companies are considering Energia for this work.

This quote, however, encapsulates the cultural war that still goes on sometimes between Russia and the U.S.:

“[Russian] achievements in docking sites and [thermal protection equipment] production are quite competitive, but I am not sure that the Americans will accept our offer because they not only have the task of building a spaceship but also of gaining competence in this matter,” Dmitry Payson, director of the space and telecommunication technology department in Russia’s Skolkovo hi-tech hub, told Izvestia.

In interviewing many Russian and American space engineers over the years I have found an amazing amount of contempt from each for the work of the other, often without justification. Just as the Russians above seem to falsely think that Boeing and Lockheed Martin know nothing about docking equipment or thermal protection, American engineers repeatedly have expressed to me unjustified disdain for the space station technology developed by the Russians for Mir. The result: both countries often don’t take advantage of the other’s skills.

NASA today unveiled for the press the Orion capsule scheduled for the program’s first test flight in 2014.

NASA today unveiled for the press the Orion capsule scheduled for the program’s first test flight in 2014.

Today’s unveiling was essentially a PR event designed to boost political support for the Space Launch System (SLS) and the Orion capsule program. And though we should definitely give kudos to Lockheed Martin for its progress on Orion, it is also important to note that the building of this capsule took 8 years and about $6.5 billion. And it won’t go into space for still another two years at best. Compare that to SpaceX’s Dragon, which took about four years from concept to launch, with a cost of about $1 billion.

It is this contrast that is worrying the political supporters of SLS and Orion. Consider for example this quote from the above article:

But the Orion schedule assumes steady funding by Congress, which is an open question given the current debate over federal budget deficits, taxes and a general push to reduce federal spending. “We have to be concerned about that because we are in an era of government spending where you have to do more with a limited amount,” Nelson said. “That, of course, is going to be one of the main things we’re going to have to look at in the future.” [emphasis mine]

Nelson has been a big backer of SLS from the moment Congress decided to force it down NASA’s throat. It is very clear from his comments above however that he recognizes the political difficulties that this very expensive program faces.

As I’ve said before, I expect SLS to die sometime in the next three years. Faced with a ungodly federal deficit, the next Congress is going to look for ways to save money and — assuming the commercial space companies like SpaceX continue to have success — Congress will see this program as one of those ways.

Russia’s Deputy Prime Minister said today that his country needs to expand its commercial space services and grab market share from the United States and Europe.

The competition heats up: Russia’s Deputy Prime Minister said today that his country needs to expand its commercial space services and grab market share from the United States and Europe.

I wonder if these comments stem from a realization that — because Russia’s Proton rocket, its main commercial space product, is twice as expensive as SpaceX’s Falcon 9 — Russia faces a significant loss of business if it does not adapt.

The cost of launch: Clark Lindsey posted today this interesting cost comparison between the Falcon 9 and the Russian-built Proton rocket.

The essence is this: The Proton rocket costs twice as much as the Falcon 9. If SpaceX can make a profit charging these low numbers, the launch industry is going to see a major shake out in the coming years.

The most powerful rocket presently in service, the Delta-4 Heavy, successfully launched a U.S. surveillance satellite this morning.

The most powerful rocket presently in service, the Delta-4 Heavy, successfully launched a U.S. surveillance satellite this morning.

The booster features three core rocket boosters and is topped with a second stage to place payloads into orbit. It is 235 feet tall (72 meters) and can carry payloads of up to 24 tons into low-Earth orbit and 11 tons to geosynchronous orbits.

SpaceX’s proposed Falcon Heavy would launch about 50 tons into low Earth orbit, making it twice as powerful, should it be built. The next obvious question, which I can’t answer at the moment, is how do these two rockets compare in terms of cost?

The second phase of NASA’s robotic refueling demo on ISS has successfully proven that a robot can remove a satellite fuel cap not designed for refueling.

The second phase of NASA’s robotic refueling demo on ISS has successfully proven that a robot can remove a satellite fuel cap not designed for refueling.

The fuel cap design is a duplicate of that used by several climate research satellites presently in orbit. These satellites were not designed to be refueled, but if they could be refueled, their usefulness in orbit could be doubled, even tripled. This test is intended to demonstrate that a robot could refuel them.

The last phase of this robotic demo will take place in August, when the robots will attempt to pump a simulated fuel into the demo satellite.

NASA has delayed the first test flight of Orion’s launch abort system by two years to 2017.

NASA has delayed the first test flight of Orion’s launch abort system by two years to 2017.

NASA officials have been warning since last year that work on Orion would be slowed to keep pace with the development of SLS and its launch infrastructure. The agency has proposed trimming Orion’s $1.2 billion budget back to $1 billion for 2013. With the high-altitude abort test facing at least a budget-driven delay, the Langley team has proposed conducting one or more less-expensive tests in its place. Ortiz said conducting a hot-fire test in 2015 or 2016 would “keep the [launch abort system] project moving forward and help alleviate risk.”

I predict that Dragon will not only test its launch abort system first, it will have humans flying on it before Orion. And Dragon will do this for a fraction of the total cost that Orion and SLS spend per year. I also predict that when Dragon does this, Congress will finally begin noticing this disparity, and SLS will die unlaunched.

An asteroid that was discovered only four days before it flew by the Earth on June 14 has turned out to be much bigger than first thought.

An asteroid that was discovered only four days before it flew by the Earth on June 14 has turned out to be much bigger than first thought.

This particular asteroid may not have been a danger, but much of the concern was rooted in the late warning of its detection — 2012 LZ1 was spotted only four days before closest approach. One of the reasons for its late discovery is because it was detected in Southern Hemisphere skies, part of the world were we have few asteroid-watching programs. If it had been on a collision course with Earth, a few days notice is no time at all.

So, in the aftermath of the flyby, astronomers at the famous Arecibo Observatory in Puerto Rico used radar to image the interplanetary interloper (pictured top). What they uncovered was a surprise: Asteroid 2012 LZ1 is actually bigger than thought… in fact, it is quite a lot bigger. 2012 LZ1 is one kilometer wide (0.62 miles), double the initial estimate.
