Building Boeing’s CST-100 manned capsule, the smart way
Building Boeing’s CST-100 manned capsule, the smart way.
From pressure seals used on the international space station to rendezvous and docking sensors developed for the Pentagon’s Orbital Express experiment, Boeing is drawing heavily on heritage space and aviation programs for its proposed CST-100 commercial human spacecraft.
Cheaper also.

A preview of the new Mars unmanned rover Curiousity, set for launch on Saturday
A preview of the new Mars unmanned rover Curiousity, set for launch on Saturday. This is the part of its mission that scares me the most:
The final stages of the entry, descent and landing sequence will be especially tense as the rover, dubbed Curiosity in a student naming contest, is gently lowered to the surface on cables suspended from a rocket-powered “sky crane” making its debut flight. Too large to use airbags like those that cushioned NASA’s Pathfinder, Spirit and Opportunity rovers, Curiosity will rely instead on landing rockets positioned above the rover, avoiding the challenge of coming up with a reliable way to get a one-ton vehicle off of an elevated, possibly tilted lander. Instead, Curiosity will be set down on its six 20-inch-wide wheels, ready to roll.
If it works.

ESA tracking station loses contact with Phobos-Grunt
The ESA tracking station that had made contact with Phobos-Grunt earlier this week failed repeatedly yesterday to re-establish contact.

An update on the efforts to save Phobos-Grunt
An update on the efforts to save Phobos-Grunt.
“The first pass was successful in that the spacecraft’s radio downlink was commanded to switch on and telemetry was received,” said Wolfgang Hell, ESA’s Service Manager for Phobos–Grunt. Telemetry typically includes information on the status and health of a spacecraft’s systems. “The signals received from Phobos–Grunt were much stronger than those initially received on 22 November, in part due to having better knowledge of the spacecraft’s orbital position.”
The second pass was short, and so was used only to uplink commands – no receipt of signal was expected. However, the following three passes in the early morning of 24 November proved to be more difficult: no signal was received from Phobos–Grunt.

ESA antenna contacts Phobos-Grunt again, this time downloading telemetry data
An ESA tracking station has once again contacted Phobos-Grunt, this time downloading telemetry data.
“We have again established contact with the Phobos-Grunt spacecraft, we obtained telemetry reports, they are being analyzed by our colleagues from the Lavochkin Research and Production Association,” ESA spokesman Rene Pischel said.

Training space tourists for their suborbital flight
Training space tourists for their suborbital flight.
In the NASTAR Center’s Observation Lounge, trainees can watch the centrifuge through a large window, as well as see a live video feed of its rider. Meanwhile, Henwood iterates the importance of the correct timing of breaths. “If you’re going to need it, you’re going to want to do it right.” Failing to begin the manoeuvre before the onset of the g’s can result in loss of consciousness.
“You’ll tell me when to breathe?” the first flier of the course says over the intercom to Greg Kennedy, NASTAR Center’s director of educational services and the monitor of participants’ in-flight safety.
“Yes,” Kennedy says. “Are you ready for your flight?”

The case against SpaceX
The case against SpaceX. From one of the company’s biggest supporters.
Trent Waddington raises many good points, all of which must be considered to have a clear, educated sense of where the future stands for American manned spaceflight. Two quotes:
The goal of SpaceX is human spaceflight, and the greatest repository of knowledge about human spaceflight is NASA. As such, it would appear obvious that getting NASA to help you to fly humans safely is a good idea. The way to do that is with Space Act Agreements. This is what SpaceX did under the COTS program, and later under the CCDev program.. and they got paid for the privilege. As a result, the Dragon spacecraft will soon be fully qualified as safe for human habitation on orbit as it will be berthed to the ISS and have astronauts inside it.
The problem is that NASA is a precocious customer. They know what they want, they think they know even better than you do how to make it, and they feel no guilt about changing their mind halfway through the project. As such, Space Act Agreements just totally grind NASA’s gears. They don’t have enough control. [emphasis in original]
NASA money is like heroin.. once they start taking it, most people find it very hard to stop. There’s a dependence that has grown between NASA and SpaceX, and although it is obviously a love-hate relationship, it’s going to be very hard for SpaceX to let go.. but, inevitably, they must. The current needs of NASA are very different to the long term goals of SpaceX.
And this:
Fundamentally, SpaceX has a shoddy business case which is best described as a house of cards.. that they’re still trying to play poker with.. and there’s dogs at the table, and they’re smoking cigars! Yeah, metaphor.
Read the whole thing. It’s quite good.

Russian space agency head says there is still a chance to save Phobos-Grunt
The head of the Russian space agency said yesterday that there is still a chance to save Phobos-Grunt.
“The probe is going to be in orbit until January, but in the first days of December the window will close” to re-programme it, he told Russian news agencies at Russia’s Baikonur cosmodrome in Kazakhstan.
He also said that the probe will not pose a threat, and will burn up in the atmosphere if it should fall to Earth.

Presently they are saying early January, though it appears that no one will be surprised if it gets delayed to February.

Soyuz rocket successfully launches three astronauts into orbit
A Soyuz rocket has successfully launched three astronauts into orbit.
This is the first manned launch since the shuttles were retired, and the first Russian manned mission since the failure of a Soyuz rocket in August. If all goes well, the astronauts will dock with ISS in two days.

NASA halting work on its J-2X rocket engine
Par for the course: NASA, having successfully completed a 500 second test of the J-2X rocket engine, has halted all further development work on that engine.
The NASA program to build the heavy-lift rocket is expected to get $1.2 billion per year, and yet it doesn’t have enough money to develop both its first and second stages simultaneously? Kind of proves my point that NASA’s fixed labor costs, imposed on it by Congress, makes it impossible for the agency to ever build anything at a competitive price.
The result: every project dies stillborn.
