UFO-Indicator Experiences

A Rutgers University professor has a fine paper on alien abduction. It listed five classic alien abductee symptoms:

1. "Waking up paralyzed with a sense of a strange person or presence or something else in the room.'

2. "Experiencing a period of time of an hour or more, in which you were apparently lost, but you could not remember why or where you had been."

3. "Feeling that you were actually flying through the air although you didn't know why or how."

4. "Seeing unusual lights or balls of light in a room without knowing what was causing them."

5. "Finding puzzling scars on your body and neither you nor anyone else remembering how you received them or where you got them."

Recognizing 4 out of 5 symptoms would qualify one as an alien abductee.

Space Derelicts


OObjects has a gallery of abandoned space vehicles and facilities. Pictured is a rotting Buran space shuttle, a USSR craft from Cold War days. 

Falcon 1 | Static Fire



The static firing for SpaceX's Falcon 1 rocket took place on Saturday [20 Sep 2008, CA time], as expected, and no major issues came up.

The replacement of a component in the 2nd stage engine LOX supply line would add a few extra days to the schedule, so the updated launch window estimate is now Sept 28th through Oct 1st [CA time].

Makemake

Makemake is the name given by the International Astronomical Union to the fourth dwarf planet in our Solar System. Previously known as 2005 FY9, Makemake, which is named after a Polynesian fertility god, is also classified as a plutoid.

Discovered in 2005 by astronomers from the California Institute of Technology, Makemake is smaller than Pluto, and is located in a region just beyond Neptune. Its surface may be covered in frozen methane.

Pluto Gets a New Class


The International Astronomical Union has decreed that Pluto, along with other planetoids that lie beyond Neptune, will now be classified as 'plutoids.'

Currently, only two heavenly bodies qualify for that designation, Pluto and Eris. Ceres, which is only smaller than Pluto, cannot be classified as such because it is located between Mars and Jupiter.

First Raw Images From Mars by the Phoenix Lander


Phoenix is the first probe to have successfully landed on the surface of Mars since the Viking landers of 1976.

Its 90-day mission is to analyze the soils and permafrost of Mars' arctic tundra for signs of past or present life.

The lander is equipped with a robotic arm capable of scooping up ice and dirt to look for organic evidence that life once existed there, or even exists now.

These are the first images sent by the lander to JPL

Phoenix Mars Lander Successfully Lands On Mars


After the "seven minutes of terror," NASA received communications that the Mars Phoenix Lander had successfully landed on Mars on May 25. The craft traveled 422 million to Mars in 296 days.

Bizzare Cloud Phenomenon Before the Quake


Bizzare cloud phenomenon were observed about 30 minutes prior to the May 12 earthquake in Sichuan, China. The clouds were luminous and glowing. Could these clouds precursor to earthquakes?*

The video was recorded in Tianshui, Gansu province ~450km northeast of epicenter, by someone using a cell phone.

The earthquake in Sichuan, measured 7.9 on the Richter scale, killed at least 51 thousand (around 30 thousand more are missing).

*Wikipedia has an entry for earthquake light.

13-yr Old Corrected NASA

A 13-year old German schoolboy handed NASA an egg on the face, by correcting the agency's estimates on an asteroid collision.

Nico Marquardt calculate that there was a 1 in 450 chance that the Apophis asteroid will collide with Earth, far from NASA's estimate of 1:45,000 chance of it happening.

And the best part is? NASA concurred.

SpaceX Completes Falcon 1 Engine Qualification


Space Exploration Technologies Corp. (SpaceX) announced today that it has completed the qualification testing program of its Merlin 1C next generation liquid fueled rocket booster engine for use in the Falcon 1 rocket. Tests were conducted at the SpaceX Texas Test Facility near Waco, TX, on a Merlin 1C configured for powering the first stage of a Falcon 1 rocket.

The single Merlin 1C will power SpaceX’s next Falcon 1 mission, scheduled to lift off in Spring of 2008 from the SpaceX launch complex in the Central Pacific atoll of Kwajalein. The far larger Falcon 9 uses nine Merlins on the first stage, and a single Merlin in vacuum configuration powers the Falcon 9 second stage.

The Merlin 1C is an improved version of the Merlin 1A ablatively cooled engine, which lofted the Falcon 1 on its first flight in March 2006 and second flight in March 2007. The regeneratively cooled Merlin 1C uses rocket propellant grade kerosene (RP-1), a refined form of jet fuel, to first cool the combustion chamber and nozzle before being combined with the liquid oxygen to create thrust. This cooling allows for higher performance without significantly increasing engine mass.

In its Falcon 1 configuration, Merlin 1C has a thrust at sea level of 78,000 lbs, a vacuum thrust of 90,000 pounds and a vacuum specific impulse of 301 seconds. In generating this thrust, Merlin consumes 300 lbs/second of propellant and the chamber and nozzle, cooled by 90 lbs/sec of kerosene, are capable of absorbing 10 MW of heat energy.

Beam Me Up, John


NASA will beam a copy of Beatles' Across the Universe to Polaris, the North Star using the Deep Space Network. The celestial release of the song will mark the 50th anniversary of the space agency and the 45th anniversary of the Deep Space Network. The song will be transmitted using the MP3 format.

No word if aliens can upload it on their peer-to-peer networks.

Mullahs in Space


Iran launched a rocket into space to commemorate the establishment of a space center. The rocket, named Safir -1 (Explorer-1), is probably a sounding rocket similar to the one launched last February. The White House deems the launch as a ballistic missile test in disguise.
