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.

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

Since Xcor has not yet flown Lynx, and Excalibur Almaz as a lot of work to do to make its Soviet-era modules flyable, I would bet that this news release is mostly public relations hype, centered as much on raising investment funds for both companies as it is about training astronauts.
