Space Travel VISIT OUR MOTHER SITE AT http://dunstan-times000.tripod.com/ IN THE ASTRONOMY SECTION.Ever wonder if we will ever reach the stars? Well we will and this equation may be the actual answer P RT nkT where P RT nkT = = å r where r = mass density,
n = number density, k = Boltzmann’s constant ANALYTIC
MODEL PREDICTS THAT USEFUL THRUST, Isp CAN BE OBTAINED
FROM A THETA-PINCH Thruster If
one couldn't go faster than light, the round trip to the nearest star, would take at least eight years, and to the center
of the galaxy, at least eighty thousand years. If the space ship went very near the speed of light, it might seem to the people
on board, that the trip to the galactic center had taken only a few years. one has to use technical
terms, like closed time like curves, which are code for time travel... Where do I start..how about here Taking a cue from biology, Constantinos Mavroidis, director of
the Computational Bionanorobotics Laboratory at Northeastern University in Boston, is exploring an alternative approach to
nanotech: NIAC is pleased to announce that 12 Phase I concepts have been selected for an award from the 158 proposals that were submitted.

I have having a wonderful time with my studies of space travel= to time travel...if you travel fast
enough you could return before you start as in this lovely poem... There was a young lady of Wight, Her is a math problem for your teacher......In the last 100 years or so, people began to realize that
other forms of geometry were possible, in which the angles of a triangle, need not add up to a hundred and 80 degrees.
Consider, for example, the surface of the Earth. The nearest thing to a straight line on the surface of the Earth, is what
is called, a great circle. These are the shortest paths between two points, so they are the roots that air lines use. Consider
now the triangle on the surface of the Earth, made up of the equator, the line of 0 degrees longitude through London, and
the line of 90 degrees longtitude east, through Bangladesh. The two lines of longitude, meet the equator at a right angle,
90 degrees. The two lines of longitude also meet each other at the north pole, at a right angle, or 90 degrees. Thus one has
a triangle with three right angles. The angles of this triangle add up to two hundred and seventy degrees. |

Answer provided by Lynn Cominsky (SSU E/PO Director): A common event often mistaken by people in the sky to be a Gamma-Ray burst is an Iridium Flare. If you visit this link
http://www.heavens-above.com, then put in your latitude and longitude, you will be able to see if there were any of these flares reported during this
time. Fomalhaut, a 200-million-year-old
star, is a mere infant compared to our own 4.5-billion-year-old Sun. It resides 25 light-years away from the Sun. Located
in the constellation Piscis Austrinus (the Southern Fish), the Fomalhaut ring is ten times as old as debris disks seen previously
around the stars AU Microscopii and Beta Pictoris, where planets may still be forming. If our solar system is any example,
planets should have formed around Fomalhaut within tens of millions of years after the birth of the star. The Hubble images also provide a glimpse of the outer planetary region
surrounding a star other than our Sun. Many of the more than 100 planets detected beyond our solar system are orbiting close
to their stars. Most of the current planet-detecting techniques favor finding planets that are close to their stars. "The size of Fomalhaut's dust ring suggests that not all planetary
systems form and evolve in the same way — planetary architectures can be quite different from star to star," Kalas explained.
"While Fomalhaut's ring is analogous to the Kuiper Belt, its diameter is four times greater than that of the Kuiper Belt."The astronomers used the Advanced Camera for Surveys' (ACS) coronagraph
aboard Hubble to block out the light from the bright star so they could see details in the faint ring. Doomed Star Eta Carinae Even though Eta Carinae is more than 8,000 light-years away,
features 10 billion miles across (about the diameter of our solar system) can be distinguished. Eta Carinae suffered giant
outburst about 150 years ago, when it became one of the brightest stars in the southern sky. Though the star released as much
visible light as a supernova explosion, it survived the outburst. Somehow, the explosion produced two lobes and a large, thin
equatorial disk, all moving outward at about 1.5 million miles per hour. Estimated to be 100 times heftier than our Sun, Eta
Carinae may be one of the most massive stars in our galaxy.

Rather than starting from scratch, the concepts in Mavroidis's NIAC-funded study employ pre-existing,
functional molecular "machines" that can be found in all living cells: DNA molecules, proteins, enzymes, etc. This bio-nanorobot envisioned by Constantinos Mavroidis and
colleagues resembles a living cell, biological molecules
are already very adept at manipulating matter at the molecular scale. The rearranging of atoms that makes these feats possible
is performed by hundreds of specialized enzymes and proteins, and DNA stores the code for making them. Making use of these "pre-made" molecular machines is called "bio-nanotech.""Why reinvent the wheel?" Mavroidis says. "Nature has given us all this
great, highly refined nanotechnology inside of living things.
A concept he proposes is a "second skin" for astronauts to wear
under their spacesuits that would use bio-nanotech to sense and respond to radiation penetrating the suit, and to quickly
seal over any cuts or punctures.
Imagine trekking in a lunar rover across miles of the Moon's rough surface. Your mission: to explore a crater with suspected
deposits of ice. 
The Vision for Space Exploration calls for human and robotic missions to the Moon, Mars and beyond. To realize these ambitious
goals, we will need more powerful and efficient propulsion and power-generation systems -- systems that can thrust a spacecraft
out of Earth's orbit to the far reaches of the Universe.
