Bad news for that November 30 shuttle launch date: Two cracks have been found on the aluminum body of Discovery’s external tank.
Engineers expect to get Cassini, which went into safe mode on November 2, back in operation by next week.
The up and down state of the Iranian space program.
At least one expert claims that the mystery missile launch off the California coast on was merely an optical illusion. Key quote:
John Pike of the security analyst group globalsecurity.org said the video shot by a news helicopter owned by KCBS is an optical illusion. Pike said the video is of an airplane heading toward the camera and the contrail is illuminated by the setting sun. He said the object can’t be a rocket because it appeared to alter its course.
Mystery rocket launch yesterday off of the California coast.
In addition to the hydrogen leak on Discovery, NASA is now dealing with a crack in the foam insulation on the shuttle’s external tank.
The second test launch of the Falcon 9, with the first flight of the Dragon capsule, has been postponed again. It is now set for December 7.
Cassini went into safe mode on Tuesday, November 2nd. At the moment engineers expect it to take at least another week to get the spacecraft back to normal.
Discovery’s launch is now officially postponed until no sooner than November 30.
Here are the first images of Deep Impact’s flyby of Comet Hartley 2. The first is a montage, the sequence in time going clockwise. The second is a close-up of the second image.
The feature that I find most intriguing is the narrow smooth waist of the comet’s dogbone shape. The whole thing looks almost like a piece of taffy that’s being pulled apart.
It isn’t the first time he’s said it, but Burt Rutan, designer of SpaceShipOne, says he is retiring from Scaled Composites.
Discovery’s launch is scrubbed again, this time due to another hydrogen leak. Next possible launch date is Monday, which means it is possible the launch will be delayed until early December.
In a paper posted tonight on the Los Alamos astro-ph website, an astronomer is proposing an early warning system for asteroid impact. Key quote from the abstract:
This system, dubbed “Asteroid Terrestrial-impact Last Alert System” (ATLAS), comprises two observatories separated by about 100km that simultaneously scan the visible sky twice a night, and can be implemented immediately for relatively low cost. The sensitivity of ATLAS permits detection of 140m asteroids (100 Mton impact energy) three weeks before impact, and 50m asteroids a week before arrival. An ATLAS alarm, augmented by other observations, should result in a determination of impact location and time that is accurate to a few kilometers and a few seconds.
First close-up photos of Comet Hartley 2 reveal a space peanut.
Watch the Deep Impact flyby of Hartley 2 this instant (11:06 AM eastern)! The images are incredible. Update: The fly-by is over, but the live stream is still available (as of 11:30 am Eastern), showing some of the images taken. The comet itself is a peanut-shaped object about two miles long, with a jet of water coming out one end.
An electrical problem on the space shuttle Discovery could delay tomorrow’s launch. Update: NASA has decided to definitely delay the launch until Thursday, at the earliest.
NASA has completed a significant upgrade of its Deep Space communication system. These unheralded antennas and the engineers who maintain them make it possible for scientists to communicate with the far flung planetary probes in orbit around Venus, Mars, and Saturn, as well as the spacecraft visiting comets or traveling beyond the edge of the solar system.
The last launch of the space shuttle Discovery has been moved to Wednesday afternoon in order to give engineers time to test their repairs.
The commercial suborbital industry responds to the recent science paper that said that the soot from their rocket engines might cause to global warming.
Yesterday SpaceShipTwo completed its second successful free flight (via Clark Lindsey at www.rlvnews.com). The results:
Flew to more aggressive stall indication. Evaluated handling and stability through several maneuvers. Expanded envelope to 230 KTAS and 3g’s. Roll evaluation. Full stop landing.
Engineers have discovered two new leaks on Discovery as it sits on the launchpad. It appears the Monday launch has been delayed at least one day.
On October 22, the International Space Station passed Mir’s record for the longest continuous occupancy, just short of 10 years.
Our government at work! The FAA has given SpaceX a license to launch the Dragon capsule, scheduled for a November 18 launch on the Falcon 9 rocket, but not yet given them a license to land.
Is this a great country or what? The company that is performing the zero gravity beer test on November 19 is selling advertising space on the astronaut’s flight suit to anyone with a few thousand dollars cash.
China today announced plans to complete its first space station by 2020.
Bigelow is expanding its factory, and here’s a gallery of images showing the work’s progress.
NASA is begging money from billionaires for an interstellar travel project. Sounds cool I know, but wouldn’t it be more worthwhile right now for those billionaires to invest their money in developing low cost rockets so we can simply get into space cheaply?
Treaty language being written at a United Nations conference on biodiversity is so vague it threatens to bar almost all new development. Here is the language, via Science:
8 (w) Ensure, in line and consistent with decision IX/16 C, on ocean
fertilisation and biodiversity and climate change, in the absence of science-based, global, transparent and effective control and regulatory mechanisms for geo-engineering, and in accordance with the precautionary approach and Article 14 of the Convention, that no climate-related geoengineering activities (1) that may affect biodiversity take place, until there is an adequate scientific basis on which to justify such activities and appropriate consideration of the associated risks for the environment and biodiversity and associated social, economic and cultural impacts, with the exception of small scale scientific research studies that would be conducted in a controlled setting in accordance with Article 3 of the Convention, and only if they are justified by the need to gather specific scientific data and are subject to a thorough prior assessment of the potential impacts on the environment.(1) Without prejudice to future deliberations on the definition of geo-engineering activities, understanding that any technologies that deliberately reduce solar insolation or increase carbon sequestration from the atmosphere on a large scale that may affect biodiversity (excluding carbon capture and storage from fossil fuels when it captures carbon dioxide before it is released to the atmosphere) should be considered as forms of geoengineering which are relevant to the Convention on Biological Diversity until a more precise definition can be developed. Noting that solar insolation is defined as a measure of solar radiation energy received on a given surface area in a given hour and that carbon sequestration is defined as the process of increasing the carbon contact of a reservoir/pool other than the atmosphere. [emphasis mine]
This language is so broad that, if agreed to by the United States, it could easily put almost any activity that affects the environment, including technology, business, property, recreation, or practically anything at all, under the control of UN regulators.
But wait, there’s more. The goal of this UN conference, to quote their own webpage, is to achieve “a significant reduction of the current rate of biodiversity loss at the global, regional and national level as a contribution to poverty alleviation and to the benefit of all life on Earth.” Obviously, this UN group is not merely interested in protecting the biodiversity of life on Earth, but to also redistribute the wealth so as to help poorer nations.
God help us if our government agrees to this.
Save that date! November 19 has been set for the first test of beer drinking in zero gravity.
