A deleted scene from "Bladerunner."



No, actually it is Beijing.

Military choppers firing blanks over Miami



How stupid are these people? Seriously, conducting this kind of simulated fire activity over a city without clearly and openly explaining the exercise to the public should be illegal.

Space food past and present




"The AFT project is responsible for providing space flight crews with a food system that is safe, nutritious, and acceptable to the crew, while efficiently balancing appropriate vehicle mass, volume, waste, and food preparation time for exploration missions. This will require a packaged food system with a shelf life of 3 to 5 years – current shuttle and ISS food system technologies do not meet these requirements. Food not only provides nutrition for astronauts, but also enhances the psychological well-being of the crew by establishing a familiar element in an unfamiliar and hostile environment."

Selatan Space Program



"My Space Programme, Selatan was Initiated, standalone, in 1980, involves the design, simulation and construction of Spacecraft Propulsion and its system. All this is made Possible by a collaboration. My Space Programme primarily targeted for sub-orbital space tourism flight servicing for general public and its variant codenamed Master Blaster for superior water Defence capability. My Space Programme does not include, at this point of time, Moon or Mars mission.

I personally invite international Investors , Sponsors , Contractors (Airframe / engine) for smart partnership and collaboration while Reaping Rewards from patent sharing and Intellectual Property filings by forming a Joint Venture or a consortium, as Being a part of My Space Programme Initiatives (MSPI) . The cans headquarters be located anywhere The annual London, Paris or New York, as good as it gets. This year 2013 is a year for MSPI campaign garnering support leading to JV setup.

Road maps include 1. static modeling, public sales, in the 1st year (2014) 2. functional modeling, government / corporate sales, in the 2nd year (2015) 3. mockup, government / corporate sales, in the 2nd year (2015) 4. prototyping, government / corporate sales, start in 2nd year, to be completed in the 5th year (2015 to 2018) 5. assembly plant, government / corporate sales."  - Translated by Google from http://space.ace8118.com/

Sounding rocket COMPERE experiment


"The flight experiment was performed in May, 2008 in Kiruna, Sweden. It has been a benchmark type of experiment on fluid behavior in tanks to test hypotheses and numerical predictions. This experiment has been intended to partially fill in the objectives of the ESA MAP project AO-2004-111 (Convective boiling and condensation). The SOURCE experiment is still going on to serve the needs of the COMPERE research group whose mandate is to investigate the behavior of propellants in spacecraft launcher tanks.

The main element of the SOURCE module is a transparent cylindrical container which is filled with a test liquid (HFE-7000) during the ballistic phase of the sounding rocket. The container has a linear axial temperature distribution which is achieved prior to the launch by heating the upper part. It is pressurized with nitrogen gas at 3 bars."

Steak Drop What If

From what height would you need to drop a steak for it to be cooked when it hit the ground?

Image of Hiroshima Mushroom Cloud from Ground


"TOKYO — A rare photo showing the mushroom cloud from the Hiroshima atomic bombing in two distinct parts, one above the other, has been discovered in the city, a museum curator said Wednesday.

The black-and-white picture is believed to have been taken about half-an-hour after the bombing on August 6, 1945, around 10 kilometres (six miles) east of the hypocentre.

"The existence of this shot was always known in history books, but this is the first time that the actual print has been discovered," said a curator at the Hiroshima Peace Memorial Museum.  "A shot showing the mushroom cloud split into two like this is very rare." The photo was found among articles related to the atomic bombing now owned by Honkawa Elementary School in Hiroshima city, she said.  The best-known pictures of the aftermath of the bombing were taken from the air by the US military. An American B-29 bomber named Enola Gay dropped the atomic bomb nicknamed "Little Boy", turning the western Japanese city into a nuclear inferno and killing an estimated 140,000 in the final chapter of World War II.  Three days later another atomic bomb -- "Fat Man" -- was dropped on the city of Nagasaki, claiming the lives of another 70,000."

3D printer in the office!


One great part of working at a large science institution is that you get cool things at work.  This is a 3D printer that we just got in the office, here is has printed out a shark, comb, chain(!) and a nut and bolt.  My hope is that we can print out a 38mm Von Karman nosecone some day soon.  These are printed on fairly strong but largely porous plastic material.  Any ideas on how to reinforce/seal these up for use on a rocket?  I suppose a layer of fiberglass or maybe just filling the outer layer with epoxy?

Tangentially related video dump



These videos are about guns, electronics, and metallurgy. One could make the argument that these things are almost aerospace or rocketry related. Or, one could just watch the videos and enjoy.

Dropping a red hot metal sphere into water


This is the result of the Leidenfrost effect.

Ground penetrating warhead


So as you can perhaps tell, this webpage just got wider by 110 pixels.  Does this cause any problems?  Videos and images can now be significantly larger, the last 20 or so posts will be updated.

The strange tale of the Lebanese space race






"LET me take you back to 1960. It is three years after the launch of Sputnik 1 and Manoug Manougian is a young mathematics and physics lecturer at Haigazian College in Beirut, Lebanon, with a fascination for rocketry.

At a time when the global focus was on space exploration, 25-year-old Manougian decided to harness this excitement to teach science and mathematics. Gathering together a group of like-minded students, he formed a small rocketry society and began to experiment with solid rocket fuels at a farm belonging to the family of one of the students."

Man shoots at boss with AK-47



"Texas Armoring Corporation (TAC), was tired of customers asking if his company's bullet-resistant glass in its armored cars actually resisted bullets. So the CEO asked his employee to shoot at him with an AK-47. It's loud, scary, dangerous, and completely awesome."

And let me throw in a preemptive: "That's what she said."

Census Dot Map


My Brooklyn neighborhood is pitch black, but the country house is a dot in a sea of white.
There are dots in places known not to have anyone, so this must not be 100% accurate.
