We’re here to help you: The EPA has approved a warning label for its approval of 15% ethanol gasoline.
EPA says tests show E15 won’t harm 2001 and newer vehicles, which have hoses and gaskets and seals specially designed to resist corrosive ethanol. But using E15 fuel in older vehicles or in power equipment such as mowers, chainsaws and boats, can cause damage and now is literally a federal offense.
Capitalism in space: China has purchased a three Earth observation satellite constellation from a United Kingdom firm.
The launch of a military satellite out of Wallops Island, Maryland has been delayed until Wednesday.
Astronauts retreated to their Soyuz lifeboats early today as a piece of space junk zipped less than 1000 feet past the station.
A rocket launch tonight at Wallops Island will be visible to most of the mid-Atlantic eastern United States.
We’re here to help you! A experiment with the nation’s electric grid could mess up traffic lights, security systems and some computers — and make plug-in clocks and appliances like programmable coffeemakers run up to 20 minutes fast. Then there’s this quote:
A lot of people are going to have things break and they’re not going to know why,
Another private space plane moves forward.
Want to send a probe to another planet? Do it cheaply, as these scientists did.
The cost of solar energy is plummeting.
Though it can’t work in many places in the world and therefore can’t completely replace the electrical grid, this is still good news.
An evening pause: Note how long it takes for the 747 to get off the ground. The plane is big and heavy.
Cassini has directly sampled the plumes from Enceladus and discovered a salty ocean-like spray.
The new paper analyzes three Enceladus flybys in 2008 and 2009 with the same instrument, focusing on the composition of freshly ejected plume grains. The icy particles hit the detector target at speeds between 15,000 and 39,000 mph (23,000 and 63,000 kilometers per hour), vaporizing instantly. Electrical fields inside the cosmic dust analyzer separated the various constituents of the impact cloud.
The data suggest a layer of water between the moon’s rocky core and its icy mantle, possibly as deep as about 50 miles (80 kilometers) beneath the surface. As this water washes against the rocks, it dissolves salt compounds and rises through fractures in the overlying ice to form reserves nearer the surface. If the outermost layer cracks open, the decrease in pressure from these reserves to space causes a plume to shoot out. Roughly 400 pounds (200 kilograms) of water vapor is lost every second in the plumes, with smaller amounts being lost as ice grains. The team calculates the water reserves must have large evaporating surfaces, or they would freeze easily and stop the plumes.
From Clark Lindsey: Branson says Virgin Galactic will fly a suborbital flight within a year.
Busy day for travel to and from ISS: The European unmanned ATV freighter Johannes Kepler burned up in the atmosphere even as a Russian Progress freighter was launched.
In related news, the U.S. and ESA are in negotiations to merge the European unmanned ATV freighter program with NASA’s manned Orion derivative. At the same time, Europe has announced its plans to test fly a reusable space plane.
The first Soyuz launch from French Guiana has now been scheduled for October 20, 2011.
According to the chief of the Russian space agency, it presently does not have the capacity to produce additional Soyuz capsule for tourist flights.
The cost of rare earth metals used in electronics has soared to record levels in the past two weeks as China clamps down on illegal mining and limits supplies.
A prototype of an unmanned sailing ship will begin a test voyage this fall.
Although Harbor Wing will operate without a captain and crew by sailing on a pre-programmed course, “the man is always in the loop,” Ott said. An operator, seated at a computer that could be hundreds of miles away, can control the craft with keystrokes that relay commands via satellite. The transmission gap, from order to receipt, is only 18 seconds, which “on the open ocean is not much,” he said, “so you have very close control.”
An evening pause: Let’s take a strange journey, down 275 feet deep into a well. No sound, but fascinating nonetheless.
NASA is about to decide on its shuttle heavy-lift replacement, and it looks like it will be almost entirely shuttle-derived.
As I have said previously, this rocket will almost certainly never fly. NASA has to start over after spending billions and years developing Constellation, and is being given less money and time to do it.
And even if I am wrong and this rocket does fly, I bet it will do only one flight and then be retired as too costly.
Turf war: SpaceX has sued a NASA safety expert (with ties to the Ares rocket program) who questioned the safety of the Falcon 9 rocket.
This ain’t good. One of the reasons ESA controllers recently put the comet probe Rosetta into hibernation for two and a half years was in order to buy time to solve a serious technical problem.
Mission managers said the hibernation will permit Rosetta to rest its four reaction wheels, two of which have shown signs of degradation. The satellite needs three to function, and one of the two problem wheels will be used only as a spare when the satellite is awakened in January 2014 in preparation for its approach to a comet.
During a tanking test of the space shuttle Atlantis today a valve to the main engines leaked, requiring replacement and raising questions whether the July 8 launch date can be met.
Second X-51 hypersonic flight crashes prematurely.
After what the US Air Force described as a ‘flawless’ flight to the launch point aboard a Boeing B-52 mothership, the X-51 was successfully boosted to Mach 5.0 by a rocket booster. The Pratt & Whitney Rocketdyne scramjet engine successfully ignited using its initial fuel, ethylene. During the immediate transition to JP-7, the conventional fuel that makes the X-51 unique, an inlet unstart occurred. A subsequent attempt to restart and reorient to optimal conditions was unsuccessful.
SpaceShipTwo completes two glide test flights within twenty-four hours.
The world’s oldest functioning light bulb: 110 years old.
Don’t bet on it: A memo signed today by a senior NASA official marks the end of the Constellation program.
All this does is make the name change of the program-formerly-called-Constellation official. The pork continues nonetheless!
