Supersonic Freefall - Red Bull Stratos CGI. Red Bull Stratos: Why Didn't Felix Free Fall for 5 Minutes? | Wired Science. Image: Red Bull Stratos Well, he did it. Felix jumped out of a balloon 128,000 feet above the Earth as part of the Red Bull Stratos jump. More on ‘Fearless’ Felix: Of course, I was watching this video live. One thing interesting at the end was the altitude. It seems the plan was to jump from 120,000 feet – but the balloon got as high as 128,000 feet at one point. I think he eventually jumped somewhere between 127 and 128 thousand feet. I guess the two jumps could have different ending altitudes. My first guess was that it has to do with the starting altitude.
I don’t normally like to start with this kinematic equation, but I am going to anyway. Here, the initial velocity (v0) would be 0 m/s and y – y0 would be -26,000 feet or -7,900 meters. Of course, this calculation is wrong. Let me start with some assumptions: With this, I can just make two numerical models. From this model, I get a 128k jump time of 4 minutes and 14 seconds. This says what most people would think. Perpetual Harvest Greenhouse System. General parameters of an Alcubierre Warp Drive in Higher Dimensional Spacetime Extrapolating success with Harold White - NASA research. Talk Polywell has some calculations of what might be achieved with the Harold White space warping work given plausible power generation and propulsion systems.
This information was provided by Paul March who is working on the NASA project to try to create a detectable warping of space. 1. First have a successful creation and detection of a one part in ten million space warp 2. Develop and increase the level of space warping to a full warping of space 3. 4. Assuming we use a 100,000 kg vehicle with an initial velocity of 0.1 times the speed of light (c), with green light (6.0x10^14Hz) lasers for our warp field oscillators, a toroidal warp field cavity that has a superconductive Q-Factor of 10^8, with an input power of 1,000 GWe or 1.0 terawatt (T), we could expect a net light speed boost factor of only 4.02c.

Credit: Université de Montréal University of Montreal researchers found that changes in gravity affect the reproductive process in plants. Gravity modulates traffic on the intracellular “highways” that ensure the growth and functionality of the male reproductive organ in plants, the pollen tube. The cells were placed into a large centrifuge, along with a camera attached to a microscope, enabling the researchers to track in real time how the cells develop in the intense gravity generated by the centrifuge. Pollen grain with pollen tubes, viewed in the scanning electron microscope.
The researchers stained specific structures within the cells, which revealed how the cellular components move around and how the cellular transport logistics responds to the changing gravity environment. Chebli and Geitmann's study will be published in the journal PLOS ONE on March 13, 2013. Dr. About the researchers: Anja Geitmann, PhD. NASA Wants to Design a Holodeck. Galactic-Scale Energy. Since the beginning of the Industrial Revolution, we have seen an impressive and sustained growth in the scale of energy consumption by human civilization. Plotting data from the Energy Information Agency on U.S. energy use since 1650 ( 1635-1945 , 1949-2009 , including wood, biomass, fossil fuels, hydro, nuclear, etc.) shows a remarkably steady growth trajectory, characterized by an annual growth rate of 2.9% (see figure). It is important to understand the future trajectory of energy growth because governments and organizations everywhere make assumptions based on the expectation that the growth trend will continue as it has for centuries—and a look at the figure suggests that this is a perfectly reasonable assumption.
(See this update for nuances.) Total U.S. Energy consumption in all forms since 1650. Growth has become such a mainstay of our existence that we take its continuation as a given. When would we run into this limit at a 2.3% growth rate? Why Single Out Solar? New evidence that comets could have seeded life on Earth. (Phys.org) —It's among the most ancient of questions: What are the origins of life on Earth? A new experiment simulating conditions in deep space reveals that the complex building blocks of life could have been created on icy interplanetary dust and then carried to Earth, jump-starting life.
Chemists from the University of California, Berkeley, and the University of Hawaii, Manoa, showed that conditions in space are capable of creating complex dipeptides – linked pairs of amino acids – that are essential building blocks shared by all living things. The discovery opens the door to the possibility that these molecules were brought to Earth aboard a comet or possibly meteorites, catalyzing the formation of proteins (polypeptides), enzymes and even more complex molecules, such as sugars, that are necessary for life.

The figure above shows all planets near the habitable zone (darker green shade is the conservative habitable zone and the lighter green shade is the optimistic habitable zone).
Only those planets less than 10 Earth masses or 2.5 Earth radii are labeled. The different limits of the habitable zone are described in Kopparapu et al. (2014). Size of the circles corresponds to the radius of the planets (estimated from a mass-radius relationship when not available). Larger version here. Location in the night sky of all the known stellar systems with potentially habitable worlds (some systems have more than one planet).

Kepler telescope's planet-hunting days crunch to a close - space - 15 May 2013. “Kepler was my North, my South, my East and West, my working week, no weekend rest, my noon, my midnight, my talks, my song; I thought Kepler would last forever: I was wrong.” So laments planet hunter Geoff Marcy, with a due nod to W. H. Auden, upon hearing the news that NASA’s Kepler space telescope is probably close to ending its search for extrasolar planets. Since its launch in 2009, Kepler has discovered 132 exoplanets and identified nearly 3000 more possible planets, including a handful of potentially rocky worlds that may be able to host life.
But the pioneering telescope has been hobbled by a damaged reaction wheel, NASA announced at a press conference today. Rest and relaxation The telescope has been watching some 150,000 stars near the constellation Cygnus for changes in brightness caused by a planet crossing, or transiting, its face as seen from Earth. Kepler started out with four reaction wheels – one to control its motion around each axis and one spare. Tragic timing Topics: ISS Photo Locations. March 2013 Since the first mission to the International Space Station over 12 years ago there have been over a million photographs taken by astronauts looking out from four hundred kilometers above Earth. Nearly all of them have been archived on NASA’s servers. I’ve crawled that archive, pulling down the location for each of the 1,129,177 photographs taken from the ISS. The Data Downloads: Files The data exists in a collection of .csv files in the folder data. If we draw a dot for the location of every photo of Earth taken from space what do we see?
Most of the photos are taken of land. Now let’s divide up the dots by mission. The map is dominated by purple, light blue, and green with some yellow. Here’s the breakdown: Photo count by mission One more thing we can do is add a map underneath to see exactly how the photos line up: Here you can see that the ISS stays between about 50° and -50° latitude as it orbits the Earth The inclination of the orbit of the station is in fact 51.6°.

TIME and Space | By Jeffrey Kluger Editors note:On Nov. 29, 2016, Google released a major update expanding the data from 2012 to 2016. Read about the update here. Spacecraft and telescopes are not built by people interested in what’s going on at home. Rockets fly in one direction: up. That changed when NASA created the Landsat program, a series of satellites that would perpetually orbit our planet, looking not out but down. Over here is Dubai, growing from sparse desert metropolis to modern, sprawling megalopolis.
It took the folks at Google to upgrade these choppy visual sequences from crude flip-book quality to true video footage. These Timelapse pictures tell the pretty and not-so-pretty story of a finite planet and how its residents are treating it — razing even as we build, destroying even as we preserve.

Space Station Astronauts Log One Million Photos. Space Station Astronauts Log One Million Photographs April 4, 2012 -- Two Russian spacecraft -- a Soyuz and Progress cargo ship -- hang above the Earth, docked to the International Space Station (ISS) while green wisps of auroral activity complete the scene.
On any average day, this photograph would be a beautiful reminder of the serenity of space and the ingenuity of mankind. But this isn't any "average" photograph. This is the one millionth photograph taken by astronauts and cosmonauts on board our orbiting outpost. Further Up Yonder. Mars colonization may require Earth soil. Twin Peaks, Mars. Courtesy of Timothy Parker/JPL/NASA Eighty thousand people recently applied for a trip to Mars, an excursion that will allegedly be funded by selling reality-TV show rights for the voyage. The company running this curious venture, Mars One, estimates that the price tag for an expedition of four astronauts—currently slotted for 2023—would be $6 billion . But the ticket’s one-way: There is no budget for bringing them back.
It wouldn’t be a suicide mission, though. It is not clear whether such a journey could be done safely for $6 billion, or at all. But that’s just the start. But there’s another, more subtle hazard of Martian homesteading that people have barely begun to think about: the lack of soil. During the Humans to Mars conference held in Washington, D.C., in May, several panelists suggested that colonists would grow food hydroponically, in water. You can grow a reasonably good tomato in water. What are the qualifications to apply? Mars One will conduct a global search to find the best candidates for the first human mission to Mars. The combined skill set of each astronaut team member must cover a very wide range of disciplines.
The astronauts must be intelligent, creative, psychologically stable and physically healthy. On this page, Mars One offers a brief introduction to the basics of our astronaut selection process. The astronaut selection process In spaceflight missions, the primary personal attributes of a successful astronaut are emotional and psychological stability, supported by personal drive and motivation. Once on Mars, there are no means to return to Earth. Mars One cannot stress enough the importance of an applicant’s capacity for self-reflection. Five Key Characteristics of an Astronaut Age The astronaut selection program will be open for applicants who are 18 years or older. There is not an upper age limit to apply for the astronaut selection program. Medical and Physical Requirements Also read: Meet the thousands of people ready to die on Mars. Aaron Hamm, an assistant hotel engineer who deals with HVAC, cooling systems, and maintenance, lacks the traditional qualifications to be an astronaut.
But that doesn't mean he wants to stay on Earth. "I felt… I was discouraged as a child [from becoming an astronaut] just because of how unbelievably competitive it is,” Hamm told Ars. “I’m a very intelligent person and I’m driven to try and achieve my dreams but, at the same time, I felt like it was an really unrealistic goal to try and pursue.
As smart as I am, there's always plenty of people that are smarter.” Hamm, an Ars forum user by the name of Quisquis, has just applied for the private Mars One colony program. For him, a large part of the appeal is that the program seeks a different type of astronaut. “I think that the Mars One mission and the idea of going somewhere that you're not coming back from for life… that's different than the general astronaut program,” he said.

Mars impact: The red planet may get hit by a comet in October 2014. Image credit: Mars: NASA/JPL/MSSS; Comet Halley: Hale Observatory; composite: Phil Plait In case you just can’t get enough impact news, it looks like Mars may actually get hit by a comet in 2014! As it stands right now, the chance of a direct impact are small, but it’s likely Mars will get pelted by the debris associated with the comet. I know. This is pretty amazing. The comet is called C/2013 A1 (Siding Spring), discovered on Jan. 3, 2013 by the Australian veteran comet hunter Robert McNaught. Observations taken at the ISON-NM observatory in New Mexico just this week have tightened up the orbit a bit more, allowing for better predictions. That’s pretty dang close. Image credit: NASA/JPL Comets are similar to asteroids: Big chunks of interplanetary debris, mostly rock, that orbit the Sun.
Image credit: NASA/JPL-Caltech/UMD Right now, the comet is over a billion kilometers from the Sun, and is (pardon the expression) stone cold. Let me be very clear: We are in no danger here on Earth.
