Directed panspermia

Panspermia – the idea that life exist across the whole Universe and it can be transferred from one location to another.

Directed panspermia – the idea that life might have been intentionally spread throughout space and seeded on the surface of other worlds by a guiding intelligence.

In August 1996, teams of scientists found in Antarctica a meteorite that contains fossils blasted off from the surface Mars about 15 million years ago. Than 4kg Stone labeled ALH84001 contains balls of carbon originating from micro-organisms while they were alive. Several tests for organic material have been performed on ALH84001 and amino acids and polycyclic aromatic hydrocarbons (PAH) have been found.

The late Nobel prize winner Professor Francis Crick, OM FRS, along with British chemist Leslie Orgel proposed the theory of directed panspermia in 1973. A co-discoverer of the double helical structure of the DNA molecule, and gen HAR1, which separates us from animals, for which Crick found it impossible that the complexity of DNA could have evolved naturally. 

The strategy of directed panspermia may have already been pursued by an advanced civilization facing catastrophic annihilation, or hoping to terraform planets for later colonization.

Panspermia

The word panspermia is Greek origin (pas/pan=all; sperma=seed), and it meen’s “seed everywhere“. Originated in Greece, where philosophers came up with the idea that life exist across thw whole Universe and it can be transferred from one location to another. Some believe that life on Earth was created by those floating “seeds”.

Statisticly, 7.5% rocks form Mars reach the Earth’s surface. The rock will travel between 100 and 16000 year and more and eventually came on Earth.

Generaly, panspermia include the deflection of interstellar dust by solar radiation pressure and extremophile microorganisms traveling through space within an asteroid, meteorite or comet.

There are three popular hypothesis:

• Lithopanspermia (interstellar panspermia) – impact-expelled rocks from a planet’s surface serve as transfer vehicles for spreading biological material from one solar system to another.
• Ballistic panspermia (interplanetary panspermia) – impact-expelled rocks from a planet’s surface serve as transfer vehicles for spreading biological material from one planet to another within the same solar system
• Directed panspermia – the intentional spreading of the seeds of life to other planets by an advanced extraterrestrial civilization, or the intentional spreading of the seeds of life from Earth to other planets by humans

Panspermia does not provide an explanation for evolution or attempt pinpoint the origin of life in the Universe, but it does attempt to solve the mysteries of the origin of life on Earth and the transfer of life throughout the Universe.

Capsule from the Hayabusa

Thousands of people flocked to an exhibition in Japan on Sunday to see a capsule from the Hayabusa space probe which was hoped to have brought asteroid dust to Earth.

Some 1,800 people were queuing in Tokyo to see the heat-proof pod, which had travelled in space with the unmanned craft for seven years, even before the exhibition opened in the morning, a Japan Aerospace Exploration Agency (JAXA) spokesman said.

More than 7,000 had visited the first public showing of the capsule by early evening, he said, adding that the space agency expects as many as 50,000 people during the five-day exhibition.

The capsule, which journeyed billions of kilometres (miles), was fired back to Earth in June.

Technical problems had plagued the Hayabusa, which at one stage spun out of control and lost contact with JAXA for seven weeks, delaying the mission for three years until the asteroid and Earth re-aligned.

When it finally latched onto the potato-shaped Itokawa asteroid, a pellet-firing system designed to stir up dust malfunctioned, leaving it unclear how much material the probe was able to gather.

Scientists hope any dust samples from the ancient asteroid in the capsule could help reveal secrets about the origins of the solar system.

The space agency has said it found “minute particles” of what it hopes is asteroid dust in the capsule, but it is expected to take months to get the final results of the analysis.

The Hayabusa project has generated great excitement in Japan.

“I was so impressed that such a small thing came back to Japan after a seven-year space journey,” said one of the visitors. “It is just amazing.”
