An update on the ongoing X-37B mission
An update on the ongoing X-37B mission.
I like this quote from the article:
Meanwhile, Boeing has begun to look at derivatives of their X-37B Orbital Test Vehicle — including flying cargo and crew to the International Space Station. Speaking this week at the Space 2011 conference —organized by the American Institute of Aeronautics and Astronautics (AIAA) and held in Long Beach, Calif. — Arthur Grantz of Boeing Space and Intelligence Systems sketched out a host of future uses for the space plane design. For one, the X-37B, as is, can be flown to the space station and dock to the facility’s common berthing mechanism. No new technology is required for X-37B to supply cargo services to the ISS, Grantz said. Also, an X-37C winged vehicle has been scoped out, a craft that would ride atop an Atlas 5 in un-shrouded mode.
The Boeing roadmap, Grantz added, also envisions a larger derivative of the X-37B space plane, one that can carry up to seven astronauts, as well as tote into Earth orbit a mix of pressurized and unpressurized cargo.

Dawn begins close-up orbit observations
Dawn begins close-up orbit observations of Vesta. More new results here.
In this orbit, the average distance from the spacecraft to the Vesta surface is 420 miles (680 kilometers), which is four times closer than the previous survey orbit.

Test flights of SpaceShipTwo resume
After a summer break, the flight tests of SpaceShipTwo have resumed. Thursday’s test appeared to a bit more exciting that previous flights:
Test card called for releasing the Spaceship from WhiteKnightTwo and immediately entering a rapid descent. Upon release, the Spaceship experienced a downward pitch rate that caused a stall of the tails. The crew followed procedure, selecting the feather mode to revert to a benign condition. The crew then defeathered and had a nominal return to base. Great flying by the team and good demo of feather system.

Scientist proposes that the superluminal neutrinos are merely measuring the true speed of light
On Thursday physicist Susan Gardner of the University of Kentucky proposed in a preprint on the Los Alamos astro-ph website that the neutrinos measured at CERN that appeared to be going faster than light were merely giving us a much more accurate measure of the speed of light.
This is only one of a plethora of papers published this last week on astro-ph discussing and attacking the CERN neutrino results. I expect the scientists will solve this mystery before too long.

Arctic ozone loss at record level
The ozone levels over the Arctic this past year were the lowest on record, caused by unusually cold temperatures.
No records for low temperature were set this year, but the air remained at its coldest for an unusually long period of time, and covered an unusually large area. In addition, the polar vortex was stronger than usual. Here, winds circulate around the edge of the Arctic region, somewhat isolating it from the main world weather systems.
“Why [all this] occurred will take years of detailed study,” said Dr. [Michelle] Santee [from NASA’s Jet Propulsion Laboratory]. “It was continuously cold from December through April, and that has never happened before in the Arctic in the instrumental record.”

Russia launches its first Soyuz rocket since the failure in August
Russia launches its first Soyuz rocket since the Progress launch failure in August.
This was a launch of a Soyuz-2 rocket, which is not identical to the Soyuz-U rocket that the Progress freighter was on. Nonetheless, the success is a good sign that they are back in business.

Five myths about China’s space effort
Five myths about China’s space effort. Key recommendation:
Recognize the significance of space as a field of competition. Beijing is not engaged in a space race with Washington. But China is engaged in a great power competition with the U.S. in which space is one arena. American decision makers should come to terms with this duality. In this regard, the Chinese are unlikely to be manipulated by American proposals on “codes of conduct” or meetings with the head of NASA. As long as Beijing and Washington are in competition, space will be one of the major venues.
And competition is not a bad thing. It is going to be the fuel that gets the human race into space.

Obama administration considering eliminating the ATF
Whoa! The Obama administration is considering eliminating the ATF in connection with the guns-to-Mexico scandal.
After a town hall meeting about Operation Fast and Furious in Tucson, Ariz. on Monday, ATF Whistleblower Vince Cefalu, who has been key in exposing details about Operation Fast and Furious, confirmed the elimination of ATF has been circulating as a serious idea for sometime now and that a white paper outlining the plan does exist.
[snip]
[However,] ATF field agents weren’t the problem with Operation Fast and Furious, high ranking officials within ATF and the Department of Justice were and still are. DOJ would eliminate ATF only to take the heat off of the Obama Administration. By eliminating the bureau, it makes it seem like DOJ is taking Operation Fast and Furious so seriously, they decided to “clear out the corruption, clean house,” however, it would only be a distraction away from the people at the top of the investigation. In fact, evidence shows the DOJ has been stonewalling the Oversight Committee investigation into the operation to protect Obama political appointees.
If true, this story suggests that there are many very high level officials in the Obama administration that are very vulnerable to prosecution over Operation Fast and Furious, and they are scrambling to find a way to protect themselves anyway possible.

NASA now claims it can launch a manned mission to lunar orbit by 2019
Forgive me if I remain skeptical: NASA is now claiming it will launch a manned mission to lunar orbit by 2019 using its Space Launch System heavy-lift rocket, the program-formerly-called-Constellation.

Mars atmosphere has more water vapor than predicted
Data from Mars Express has found that the Martian upper atmosphere has far more water vapor than predicted.
“The vertical distribution of water vapour is a key factor in the study of Mars’ hydrological cycle, and the old paradigm that it is mainly controlled by saturation physics now needs to be revised,” said Luca Maltagliati [of the Laboratoire Atmosphères, Milieux, Observations Spatiales (LATMOS) in Guyancourt, France]. “Our finding has major implications for understanding the planet’s global climate and the transport of water from one hemisphere to the other.”
“The data suggest that much more water vapour is being carried high enough in the atmosphere to be affected by photodissociation,” added Franck Montmessin, also from LATMOS, who is the Principal Investigator for SPICAM and a co-author of the paper. “Solar radiation can split the water molecules into oxygen and hydrogen atoms, which can then escape into space. This has implications for the rate at which water has been lost from the planet and for the long-term evolution of the Martian surface and atmosphere.”

Scientists push for monitoring network to collect environmental and socioeconomic data from around the world
What could go wrong? Scientists push for a monitoring network to collect environmental and socioeconomic data from around the world.
Sandy Andelman, an ecologist with Conservation International in Arlington, Virginia, discussed her work setting up a pilot project that began two years ago in southern Tanzania. In addition to basic environmental data about soils, nutrients and land cover, the project tracks agricultural practices. It also incorporates data about income, health and education that is maintained by the government. Andelman says that all the data she collects can be broken down to the level of individual households, and that initial results from the project have already prompted the Tanzanian government to adjust the way it zones agricultural land in the area. [emphasis mine]
Lord help the farmers whose lives will be tracked by this network.

Orbital Sciences restarts engine testing for its Taurus 2 rocket
Orbital Sciences has resumed engine testing for its Taurus 2 rocket.
While many have doubts about SpaceX, SpaceX has at least flown two successful flights of its Falcon 9 rocket. Orbital needs the Taurus 2 to supply ISS, and this rocket remains untested and as yet incomplete, with the schedule bearing down on them.

House proposes a budget increase for NIH
The Republican-controlled House has proposed a budget for National Institutes of Health (NIH) that is one billion more than last year’s budget, an increase from $30.7 to $31.7 billion.
What evil budget-cutters these Republicans are! Their mean-spirited budget increase has the nerve to reduce Obama’s budget request by about $120 million, equivalent to a whopping one third of one percent!
This is all shameful. For context, in 2008 NIH’s budget was $29.2 billion. Considering the state of the budget it seems unconscionable for the House to agree to any increase over $30.7 billion. In truth, it is perfectly reasonable to reduce NIH’S budget back to its 2008 number.
Too bad our present Congress, both Democratic and Republican, isn’t reasonable.

NASA has identified ninety percent of the largest near-Earth asteroids
Data from the infrared telescope WISE has now identified ninety percent of the largest near-Earth asteroids.
NASA researchers also downgraded their estimate of the number of medium-sized asteroids, saying there are 44 percent fewer than previously believed. The downside is that scientists have yet to find many of these mid-sized asteroids, which could destroy a metropolitan city.
