ILS, the company that launches the Russian Proton rocket, has lowered its prices.
The competition heats up: ILS, the company that launches the Russian Proton rocket, has lowered its prices.
The reason they have given is that the insurance rates to use their rocket have risen due to the three Proton rocket failures in the past two years and that they want to offset that cost for their customers. I suspect a second reason is the price pressure that the Falcon 9 is placing on them.

Sarah Brightman’s visit to ISS in doubt.
Sarah Brightman’s visit to ISS in doubt.
Soyuz taxi flights normally visit the International Space Station for a period of about eight days. NASA and Roscosmos are considering extending a 2015 visit to one month, however. If that happens, Brightman would have to give up her seat to a scientific researcher, who would perform some short-term experiments aboard the space station.
Roscosmos manned space flight director Alexei Krasnov had previously indicated that Russia might consider carrying two paying customers on the 2015 taxi flight. So, it would be theoretically possible for Russia to fly Brightman and the researcher. It’s unknown whether Brightman would want to spend that long aboard the space station, however, and pricing policy to longer-duration stays have not been worked out.

Physicians fight back against Obamacare.
Physicians fight back against Obamacare.
Dr. Ryan Neuhofel, 31, offers a rare glimpse at what it would be like to go to the doctor without massive government interference in health care. Dr. Neuhofel, based in the college town of Lawrence, Kansas, charges for his services according to an online price list that’s as straightforward as a restaurant menu. A drained abscess runs $30, a pap smear, $40, a 30-minute house call, $100. Strep cultures, glucose tolerance tests, and pregnancy tests are on the house. Neuhofel doesn’t accept insurance. He even barters on occasion with cash-strapped locals. One patient pays with fresh eggs and another with homemade cheese and goat’s milk. “Direct primary care,” which is the industry term for Neuhofel’s business model, does away with the bureaucratic hassle of insurance, which translates into much lower prices. “What people don’t realize is that most doctors employ an army of people for coding, billing, and gathering payment,” says Neuhofel. “That means you have to charge $200 to remove an ingrown toenail.” Neuhofel charges $50.
Neuhofel is not alone in this. The article describes other doctors who have done the same. As the bureaucratic mess from Obamacare expands and becomes increasingly impossible for anyone to handle, we are going to see this happen more and more.

The budget battle at NASA
Two stories today highlight not only the budget problems at NASA, but also illustrate the apparent unwillingness of both Congress and Americans to face the terrible budget difficulties of the federal government. In both cases, the focus is instead on trying to fund NASA at levels comparable to 2012, before the Obama administration or sequestration had imposed any budget cuts on the agency.
It is as if we live in a fantasy world, where a $16 trillion dollar debt does not exist, and where money grows on trees and we can spend as much as we want on anything we want.

Grasshopper flies again, but even higher.
The competition heats up: Grasshopper flies again, but even higher.
SpaceX’s Grasshopper doubled its highest leap to date to rise 24 stories or 80.1 meters (262.8 feet) today, hovering for approximately 34 seconds and landing safely using closed loop thrust vector and throttle control. Grasshopper touched down with its most accurate precision thus far on the centermost part of the launch pad. At touchdown, the thrust to weight ratio of the vehicle was greater than one, proving a key landing algorithm for Falcon 9.

Dragon has been successfully berthed with ISS.
Dragon has successfully berthed with ISS.
The naysayers will focus on the thruster problems on Friday. The yaysayers will focus on the fix and berthing today. The bottom line, however, is that this mission once again proves that SpaceX is a real player in the space business. Every other company has to match its achievements, most especially in price. The result will be the eventually lowering in the cost to low Earth orbit, which will then make all things possible.
And in fact, we are already seeing this, with the appearance of many new private companies or organizations, proposing all sorts of new space efforts, such as mining asteroids or sending people to Mars. The lower cost allows dreamers to consider their wild new ideas more doable. And they then go ahead and try to do it.

SpaceX has announced that they now have all of Dragon’s thrusters operating and are go for docking with ISS.
They have not announced when the docking will occur, but with the solar panels operating the capsule can function in orbit for a considerable time, giving them breathing room. And time will be necessary as both NASA and the Russians are nervous about letting any spacecraft approach ISS and will want a good number of tests to make sure all is well. The Russians are especially nervous, since they had the unfortunate experience of several collisions when they operated their space station Mir.

The Antares hot fire test of the rocket’s first stage was successfully completed tonight.
The competition heats up: The Antares hot fire test of the rocket’s first stage was successfully completed tonight.
The 29-second hot fire test took place at 6:00 p.m. (EST) on February 22, 2013 at the Mid-Atlantic Regional Spaceport’s (MARS) Pad 0A, which was designed and built over the last several years to accommodate liquid-fuel space launch vehicles. The primary goals of the test were to ensure that the launch complex’s fueling systems and the Antares stage one test article functioned properly in a fully operational environment, that engine ignition and shut down commands operated as designed, and that the dual AJ26 first stage engines and their control systems performed to specifications in the twin-engine configuration. The test included a full propellant loading sequence, launch countdown and engine ignition operation. The pad’s high-volume water deluge system flowed throughout the entire period of the test to protect the pad from damage and for noise suppression.
The first stage will now be prepped for a full scale test launch of Antares, expected in about six weeks. If that is successful, Orbital Sciences will then follow with a flight of the Cygnus capsule to ISS.

An outline of the cuts NASA would do if sequestration occurs on March 1 includes shutting down commercial crew while leaving the Space Launch System untouched.
An outline of the cuts NASA proposes if sequestration occurs on March 1 includes shutting down commercial crew while leaving the Space Launch System untouched.
I am in favor of sequestration, as it will only bring NASA’s budget back to the numbers the agency received in 2005, numbers that were then totally sufficient to build Constellation and fly the shuttle. Now that the cost of the shuttle is gone there should be sufficient cash today for everything NASA wants to do.
To favor the very expensive and not very useful SLS system over the new commercial crew contracts however is madness. I suspect this letter is meant as a lobbying sledge hammer to try to convince Congress to cancel sequestration. If it is serious, however, than say good-bye to any manned American spacecraft for at least another few years, as I expect the new private companies will not disappear, but their effort will be slowed significantly as they search for alternative funding.

The hot fire test of the Antares first stage tonight was aborted at the last second.
The planned first stage propulsion system “hot fire” test of Orbital’s new Antares medium-class rocket was halted in the final seconds of the countdown by the rocket’s flight computer, which detected an anomalous condition. The Antares team will evaluate the data from the test to determine the nature of the abort. A new date for the test has not been determined.
With any new rocket this kind of thing is to be expected. The concern here is the tight schedule that Orbital Sciences is under to get Antares and Cygnus operational. Long delays will not be good for them, considering the politics in Congress. Every delay will be used by certain politicians to get this program cut so the money can go to the very expensive Space Launch System that feeds the jobs in their districts.
Update: It appears the issue was that the computer detected a low pressure reading and aborted the burn. (A similar issue occurred on several of SpaceX’s early launches as was very quickly corrected.) A rescheduled hot burn is expected to take place next week.
