Nanosail-D has sailed home, burning up in the atmosphere on September 17
The solar sail Nanosail-D has sailed home, burning up in the atmosphere on September 17.
The flight phase of the mission successfully demonstrated a deorbit capability that could potentially be used to bring down decommissioned satellites and space debris by re-entering and totally burning up in the Earth’s atmosphere. The team continues to analyze the orbital data to determine how future satellites can use this new technology.
The concept being tested appears to use a solar sail as a navigating tool for guiding defunct satellites back into the atmosphere.

The 1960s space race: The US orbits its first living animal, Enos the chimpanzee
An evening pause: Fifty years ago today the United States succeeded for the first time in placing a living animal in orbit, four years after the Soviet’s launched the dog Laika into space. On November 29, 1961 NASA orbited a chimpanzee named Enos as a dress rehearsal for John Glenn’s orbital flight, then scheduled for early in 1962. See this article for some details about Enos difficult flight.
Since the flights of Gagarin, Titov, Shepard, and Grissom earlier in 1961, the 1960s space race had seemed in abeyance as NASA geared up for its first orbital manned mission, while the Soviets were typically silent about their plans. Yet, for those like myself who were alive at that time, the suspense never abated. What would happen next? Could the U.S. beat the Russians to the Moon? Only time would tell.

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.

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.

NASA, the federal budget, and common sense
Let’s be blunt: the federal government is broke. With deficits running in the billions per day, there simply is no spare cash for any program, no matter how important or necessary. Nothing is sacrosanct. Even a proposal to cure cancer should be carefully reviewed before it gets federal funding.
Everything has got to be on the table.
Thus, no one should have been surprised when word leaked two weeks ago that the Office of Management and Budget in the Obama administration was proposing cutting the entire unmanned planetary program at NASA, while simultaneously eviscerating the space agency’s astronomy program. No more missions to Mars. No probes to Europa or Titan. Further and longer delays before the James Webb Space Telescope is completed. And Kepler’s mission to find Earth Like planets orbiting other stars would end mid-mission.
The Obama administration has to find ways to trim the budget, and apparently it is considering eliminating these programs as a way to do it.
Yet, the money spent on space astronomy and planetary research is a pinprick. Considering that the federal government overspends its budget by approximately $3.5 billion per day, and the total amount of money spent on these two science programs equals about $2.4 billion per year, it seems senseless at first to focus on these kinds of cuts. Quite clearly, even eliminating them entirely will not put the federal budget into the black.
Now I am not one to say, “Cut the budget, but please leave my favorite programs alone!” I recognize the serious financial state of the nation, and realize that any budget suggestions I make must include significant total cuts to NASA’s budget.
As a space historian and science journalist who knows a great deal about NASA, however, I also know that there is plenty of room for cuts in NASA’s budget. By picking our priorities carefully at a time when our options are limited, NASA might even be able to accomplish more, not less, with a smaller budget.
Moreover, if I, as a space junky, think it is possible to continue NASA’s most important programs and still trim its budget by 15% to 20%, in real dollars, doesn’t that suggest that the same could be done across the entire federal government?
All it takes is a little knowledge, some common sense, and the courage to say no.
