Gravitational Corridors Could Help Spacecraft Travel The Solar System

A computer graphic depicting gravitational corridors that weave around planetary bodies.

Gravitational corridors could help spacecraft fly across the solar system like ships on ocean currents, it was revealed.  Scientists in the United States are trying to map the twisting ‘tubes’ so they can be used to cut the cost of space travel.

Space Colonization Limited By Fermi Paradox

Colonizing Galaxy Limited By Fermi Paradox 

Space Colony

For more than 50 years, many have taken the so-called Fermi Paradox to indicate that the existence of intelligent alien civilizations is an impossibility. However, a recent re-examination of the paradox points out that, rather than discounting the spread of an intelligent civilization, the Fermi Paradox merely points out that advanced civilizations with exponential growth are unlikely to exist.

Spitzer Space Telescope Celebrates 5th Birthday

Spitzer Space Telescope Celebrates 5th Birthday 

 Star-forming region in the constellation Cassiopeia.

NASA’s Spitzer Space Telescope, the last of the space agency’s Great Observatories satellites to launch, celebrated its fifth birthday recently… giving me the opportunity to post this amazing multigenerational picture of star-forming region in the constellation Cassiopeia, 6,500 light-years from Earth. The photo takes in an area equivalent to four full moons and puts on show how one generation of massive stars can give birth to the next.

Mars Express To Make Daring Flyby

Mars Express To Make Daring Flyby 

The European spacecraft Mars Express is to make a daring flyby of the Martian moon Phobos in the hope of gaining insights into its enigmatic surface, temperature and geological past, the European Space Agency (ESA) said on Wednesday.

On 23 July, the unmanned craft will swoop to within just 97 kilometres of Phobos, using a battery of instruments, including a high-resolution stereo camera, infra-red scanner and atmospheric spectrometer.
