ANYONE OUT THERE ??

Data has been flooding in from the nation’s latest space telescope, one with a 30-meter-diameter mirror (the Hubble’s, for comparison, was 2.4 meters). The initial searches for signs of life on exoplanets by 2020s telescopes found so many tantalizing hints. The new telescope, with thousands of times the capability, has searched hundreds of the nearest Earth-size exoplanets and found something astonishing: A large fraction show unusual chemistry in their atmospheres.

We are working hard to understand if any of the unusual chemistry can be attributed to gases produced by life. If geophysical or other contributions can be ruled out, we might establish that our galaxy is teeming with life, or at least microbial life.

If we instead hit a dead end with ambiguous chemical signals, we’ll need to go to the next step. Thanks to telomere gene therapy that has extended my life, I am willing and able to direct an even more capable space telescope, but that isn’t good enough. We will have to leave it to the next generations to figure out how to send the first interstellar space probes to actually travel up to tens of light years away to visit the other Earths.

 

 

The IXS Enterprise “Warp Ship”

 

The image above is Dutch designer Mark Rademaker’s CGI design concept; created to illustrate how NASA engineer Harold White’s IXS Enterprise “Warp ship” might look. White has been researching into possible methods of propelling space craft beyond the speed of light. The strongest theory involves the disruption of space-time in front and behind the craft. White claims he has calculated a plausible method that improves upon an earlier theory by physicist Miguel Alcubierre, and is working towards a proof of concept for the idea. Rademaker’s design shows large rings that would be used to create a “warp bubble” and was originally submitted for the Star Trek “Ships of the Line” 2014 calendar.

Warp propulsion is based on a theory that an object (like a spaceship) can move at speeds many times faster than the speed of light to go vast distances through space. It’s currently believed that if something reaches light speed, it would transform into energy and thus cease being whatever it used to be.

Not only that, but the fuel cost and time it would take to travel would make space voyages pretty unrealistic. However, warp propulsion gets around these obstacles by placing a spaceship within a warp field “bubble” of normal space, while the space surrounding the bubble moves extremely fast — basically warping the fabric of space-time.

Advanced Propulsion Theme Lead for NASA Engineering Directorate Harold White says creating technology to accomplish warp propulsion (a warp drive) is absolutely possible, and he’s even started work on creating it.

White explains that his team is currently working on complex math equations to help create and discover microscopic instances of these “warp bubbles.” If the results from his team’s experiments prove successful, it could be possible to create a warp engine capable of interstellar space travel. For perspective, he uses the example of traveling to Alpha Centauri (the closest star system to Earth) in just two weeks in Earth time.

Voyager 1 Nears The Edge Of The Solar System

After traveling for 37 years, Voyager I is recording pulses from the sun that confirm it has entered a different region near the edge of the solar system called interstellar space.

NASA’s Voyager I spacecraft has been steadily journeying away from the sun to the outer reaches of the solar system since its 1977 launch. As it travels farther out and enters a different region of the solar system, it’s occasionally affected by coronal mass ejections — shock waves caused from massive violent eruptions from our sun.

There have been three of these space “tsunamis” since 2012, and the third one — described by NASA on Monday — has helped the space agency confirm something it posited in late 2013: that Voyager is the first Earth craft to travel into interstellar space.

Interstellar space is the area just beyond the reach of what’s known as our heliosphere: an area where the solar wind pushes back the dense plasma of space in a sort of protective bubble. This plasma was ejected into the universe by the death of stars millions of years ago.

The plasma outside the heliosphere is about 40 times denser than the plasma that lies inside it. By using its 37-year-old cosmic ray and plasma wave instruments, Voyager has sent back signals to Earth that prove it has popped through our sun’s protective bubble and is now moving through the thicker plasma. Scientists can tell this is the case because the thicker plasma in interstellar space oscillates at a faster rate than less dense plasma and produces a different frequency when hit by the sun’s shock waves.

“The tsunami wave rings the plasma like a bell,” Ed Stone of the California Institute of Technology , the mission’s project scientist since 1972, said in NASA’s statement. “While the plasma wave instrument lets us measure the frequency of this ringing, the cosmic ray instrument reveals what struck the bell — the shock wave from the sun.”

“Normally, interstellar space is like a quiet lake,” Stone added. “But when our sun has a burst, it sends a shock wave outward that reaches Voyager about a year later. The wave causes the plasma surrounding the spacecraft to sing.”

 

Jupiter’s Watery Moon Europa

The space agency set aside $15 million in its 2015 budget proposal to start planning some kind of mission to Europa. No details have been decided yet, but NASA chief financial officer Elizabeth Robinson said Tuesday that it would be launched in the mid-2020s.

Robinson said the high radiation environment around Jupiter and distance from Earth would be a challenge. When NASA sent Galileo to Jupiter in 1989, it took the spacecraft six years to get to the fifth planet from the sun.

Last year, scientists discovered liquid plumes of water shooting up through Europa’s ice. Flying through those watery jets could make Europa cheaper to explore than just circling it or landing on the ice, said NASA Europa scientist Robert Pappalardo .Past NASA probes have flown by Europa, especially Galileo, but none have concentrated on the moon, one of dozens orbiting Jupiter. Astronomers have long lobbied for a mission to Europa, but proposals would have cost billions of dollars.

NASA will look at many competing ideas for a Europa mission, so the agency doesn’t know how big or how much it will cost, Robinson said. She said a major mission goal would be searching for life in the strange liquid water under the ice-covered surface.

Harvard astronomer Avi Loeb said going to Europa would be more exciting than exploring dry Mars: “There might be fish under the ice.”

The First Space Factory (E-Vectors INC.)

space craft power by positron reactor After gathering the materials from the moon landings , we have discovered the fuel need for space travel to other worlds . The fuel is a product from element 115 also known as Ununpentium. The product of element 115 is not  sent to earth but kept in space, on a space payload ship.

Using a Space Station type ship, large enough to house the people,the wares, and materials ,we  begin to mass produce spaceships.  The materials used are a Kevlar solution which is light weight and stronger than steel, and a product from the martian soil that absorbs water which protects against high levels of radiation.  3 D Printers are used for the configuration of the crafts.  Some of the basic components will be made on Earth  .\

We will discover the solution to space travel.  The equations  Space x Unknown = TIME  and Time x Unknown = SPACE meaning Space equals Time.   Yes when we look up at the stars ,we are looking back in tjme .  So to traveling  through space we will be traveling through time.

8.8 Billion Earth Like Planets In The Habitable Temperature Zone

By   Seth Borenstein       Space is vast, but itEarthlike Planets may not be so lonely after all: A study finds the Milky Way is teeming with billions of planets that are about the size of Earth, orbit stars just like our sun, and exist in the Goldilocks zone — not too hot and not too cold for life.

Astronomers using NASA data have calculated for the first time that in our galaxy alone, there are at least 8.8 billion stars with Earth-size planets in the habitable temperature zone.

The study was published Monday in the journal Proceedings of the National Academy of Science.

For perspective, that’s more Earth-like planets than there are people on Earth.

As for what it says about the odds that there is life somewhere out there, it means “just in our Milky Way galaxy alone, that’s 8.8 billion throws of the biological dice,” said study co-author Geoff Marcy, a longtime planet hunter from the University of California at Berkeley.

The next step, scientists say, is to look for atmospheres on these planets with powerful space telescopes that have yet to be launched. That would yield further clues to whether any of these planets do, in fact, harbor life.

The findings also raise a blaring question, Marcy said: If we aren’t alone, why is “there a deafening silence in our Milky Way galaxy from advanced civilizations?”

In the Milky Way, about 1 in 5 stars that are like our sun in size, color and age have planets that are roughly Earth’s size and are in the habitable zone where life-crucial water can be liquid, according to intricate calculations based on four years of observations from NASA’s now-crippled Kepler telescope.

If people on Earth could only travel in deep space, “you’d probably see a lot of traffic jams,” Bill Borucki, NASA’s chief Kepler scientist, joked Monday.

The Kepler telescope peered at 42,000 stars, examining just a tiny slice of our galaxy to see how many planets like Earth are out there. Scientists then extrapolated that figure to the rest of the galaxy, which has hundreds of billions of stars.

For the first time, scientists calculated — not estimated — what percent of stars that are just like our sun have planets similar to Earth: 22 percent, with a margin of error of plus or minus 8 percentage points.

Kepler scientist Natalie Batalha said there is still more data to pore over before this can be considered a final figure.

There are about 200 billion stars in our galaxy, with 40 billion of them like our sun, Marcy said. One of his co-authors put the number of sun-like stars closer to 50 billion, meaning there would be at least 11 billion planets like ours.

Based on the 1-in-5 estimate, the closest Earth-size planet that is in the habitable temperature zone and circles a sun-like star is probably within 70 trillion miles of Earth, Marcy said.

And the 8.8 billion Earth-size planets figure is only a start. That’s because scientists were looking only at sun-like stars, which are not the most common stars.

An earlier study found that 15 percent of the more common red dwarf stars have Earth-size planets that are close-in enough to be in the not-too-hot, not-too-cold Goldilocks Zone.

Put those together and that’s probably 40 billion right-size, right-place planets, Marcy said.

And that’s just our galaxy. There are billions of other galaxies.

Scientists at a Kepler science conference Monday said they have found 833 new candidate planets with the space telescope, bringing the total of planets they’ve spotted to 3,538, but most aren’t candidates for life.

Kepler has identified only 10 planets that are about Earth’s size circling sun-like stars and are in the habitable zone, including one called Kepler 69-c.

Because there are probably hundreds of planets missed for every one found, the study did intricate extrapolations to come up with the 22 percent figure — a calculation that outside scientists say is fair.

“Everything they’ve done looks legitimate,” said MIT astronomer Sara Seager.

NASA’s New Moon Probe Enters Lunar Orbit

NASA’s New Moon Probe Enters Lunar Orbit

Artist’s concept of NASA’s Lunar Atmosphere and Dust Environment Explorer (LADEE) spacecraft in orbit …

NASA’s newest lunar probe is officially orbiting the moon.

After a month-long journey, the Lunar Atmosphere and Dust Environment Explorer (LADEE) spacecraft — designed to probe the moon’s thin atmosphere and lunar dust — performed an engine burn on Sunday (Oct. 6) that took it into orbit around the moon.

While the current U.S. government shutdown has all but halted work at NASA, operations for the $280 million mission are not affected because LADEE is in a critical phase, Rachel Hoover, a spokesperson at NASA’s Ames Research Center in California told Spaceflight Now before the shutdown. NASA’s federal shutdown plan has furloughed most of the agency’s 18,000 employees, but does allow the agency to watch over spacecraft in flight like LADEE and the International Space Station.

Before arriving in lunar orbit, the LADEE spacecraft (the name is pronounced “laddie”) made three elliptical orbits around the Earth, moving into a higher orbit on each pass around the planet. Once its orbit was high enough, the moon’s gravity took over and LADEE performed its big burn to transfer to lunar orbit, mission managers have said.

LADEE now needs to perform two more lunar orbit insertion maneuvers before the probe’s approximately month-long checkout phase can begin. The probe’s next burn is scheduled for Oct. 9 and the third is scheduled for Oct. 12, which will lower it to an altitude of 155 miles (250 kilometers).

During the checkout period, scientists will test out LADEE’s laser-communications demonstration. The experiment used laser technology to send large amounts of data back to Earth. The laser communication model could allow spacecraft to send 3D information, high-definition video and other data back to ground controllers, scientists have said.

Once LADEE’s commissioning phase is finished, the probe will begin 100 days of science designed to probe the mysteries of the moon’s atmosphere and a moon dust mystery dating back to the Apollo program.

Apollo astronauts saw streamers of light on the horizon before sunrise on the moon. LADEE’s instrumentation will help scientists understand what could have caused the glow.

NASA officials wrote in a facts sheet: “Was lunar dust, electrically charged by solar ultraviolet light, responsible for the pre-sunrise horizon glow that the Apollo astronauts saw?”

LADEE will also investigate the moon’s extremely thin atmosphere. Called a surface boundary exosphere, the lunar atmosphere represents the most common kind of atmosphere in the solar system. Some planets (like Mercury), moons and even certain large asteroids play host to these kinds of atmospheres, making LADEE’s research wide reaching.

“It’s a class of atmosphere we actually don’t know that much about, so it turns out that the moon actually is a really convenient place to go and learn about this very common type of atmosphere,” Sarah Noble, LADEE program scientist, said before the probe’s Sept. 6 launch.

LADEE launched to space atop the first flight of the Minotaur V rocket from NASA’s Wallops Flight Facility on Wallops Island, Va.

Fuel of the Future

Spaceship

Alternative fuels will eventually be the thing that breaks space travel wide open, and will  make it possible to really explore most of space . As new fuel sources are discovered they will be cleaner, more efficient, and more powerful. At some point in the future alternative fuels may make it possible to go  into unknown areas of space and beyond.
