Mark Thomas. Jan 21, If an exoplanet is somewhat habitable, but incapable of evolving complex life in the time remaining, in most cases we should prepare it for eventual colonization by seeding it with plants and maybe animals that will help support colonization. Food for thought anyway, pun intended. My guess is that it will rarely, if ever, be that simple and some level of terraforming will be required.

Report Block. I have my doubts about any 'planetary protection' practice being long lasting. Having said that, I'm really referring to a more distant future rather than the immediate future. If or when diamonds, Gold, Platinum etc. Da Schneib. I think this is premature.

When we know what life is, and can identify types other than our own, it might be OK to do something like this, but until then we risk killing life we cannot identify, and that would be genocide. Jan 22, I think some people read too much science fiction. If we have yet to discover life elsewhere, and if life is not coming on spaceships, or whizzing by on their way to other places, then we are probably alone. At the very least, life or civilizations are very dispersed in the universe Anything other than long-distance communication would "infect" in both directions anyway.

I also don't think we can avoid "contaminating" planets if we try. So, we might as well do what this article says. I have always believed this way, and have always thought it was foolish and selfish to try to avoid "contamination" in the first place. If we send anything to any exo planet, we are sending life - whether we want to or not. In fact, the mathematics describing both have provided new designs for space missions, as witness the Genesis spacecraft, which returned particles from the solar wind to Earth.

The article is also available online through the AMS Web site free registration required. Authors Mason A. This is provocative stuff, but with such insights, engineers, mathematicians and physicists were able to set Genesis on a trajectory that met its misson goals with a minimal use of fuel. From the article:. On the celestial scale, transport takes a spacecraft from one Lagrange point to another until it reaches its desired destination. The orbits used to design space missions thus also determine the ionization rates of atoms and chemical-reaction rates of molecules!

Creating a statistically valid description of near-Earth asteroids demands tools that can make sense of chaotic systems. Clearly, the crossover work occurring between astronomers, mathematicians and chemists can provide unexpected insights toward this goal.

Explanation: A flying saucer from outer space crash-landed in the Utah desert in after being tracked by radar and chased by helicopters. The findings effectively discount some theoretical models of stellar genesis. This implies that an unknown process depleted oxygen from the Sun's disk of protoplanetary material prior to the coalescence of dust grains that formed the Earth.

Unexpectedly, it was not terrestrial desert soil introduced in the crash that proved most difficult to deal with during the sample analysis process but the craft's own flight-introduced compounds such as lubricants and craft-building materials.

  • After releasing the sample return capsule on September 8, , the spacecraft bus traveled back toward the Earth-Sun Lagrange Point L1. A trajectory correction maneuver was performed on November 6, , permitting the spacecraft bus to eventually leave L1 if it was not used for an extended mission. Final commands were transmitted to the bus on December 2, , [21] placing Genesis into hibernation.

    While in this "safe" mode, it will continue transmitting information about its condition, autonomously pointing its solar arrays toward the Sun. The spacecraft bus left L1 around February 1, , staying in a heliocentric orbit leading the Earth. Genesis Principal Investigator Dr. Donald Burnett sorting through the debris from the sample canister. Top: a view of the Genesis capsule and bus. Bottom: a closeup of the type of accelerometer that was installed backwards, with a pencil shown for scale. It determined that all scientific hardware meant to be curated by the Johnson Space Center could be released and were not needed for the work of the board.

    A first possible root cause of the failed deployment of the parachutes was announced in an October 14 press release. Lockheed Martin had built the system with an acceleration sensor's internal mechanisms wrongly oriented a G-switch was installed backwards , and design reviews had not caught the mistake. Instead, no contact was ever made. The same general parachute concept was also used on the Stardust cometary sample return spacecraft, which landed successfully in Template:Sun spacecraft.
