Virgin Galactic reveals LauncherOne to quarter cost of satellite launches

Virgin Galactic has revealed the next step of its plans to commercialize space flight, unveiling LauncherOne, a new launch vehicle that promises to significantly cut the cost of space exploration. The satellite launch platform will cut the cost of putting a satellite into space to potentially just a quarter of current expeditions, down to under $10m and opening up the possibility to universities and research groups.

“This new vehicle will change the whole satellite industry and space-based science research” Virgin Group founder Richard Branson said of the LauncherOne reveal. “Even before this official launch we have the largest order book of any new launch vehicle ever. The cost of putting a satellite into space before Virgin Galactic was around $30-40 million. We’ll be able to do it for under $10 million, opening up space to thousands of new groups, universities and research programs.”

LauncherOne will use the same WhiteKnightTwo ”mothership” as Virgin Galactic’s SpaceShipTwo will rely on, currently on its 100th test flight, and which will provide a moving launch point for the company’s missions. When approximately 50,000 feet above sea level, LauncherOne will be released from its berth underneath WhiteKnightTwo, free-fall for around four seconds, and then trigger its first stage rocket. After that, the second stage will fire one or more times, until the satellite payload is delivered to low-earth orbit.

“LauncherOne will go around the world at 80,000mph in 80 minutes” Branson said today. “It’s actually 90 minutes, but I thought around the world in 80 minutes sounded better!”

In LauncherOne’s favor is WhiteKnightTwo’s flexibility: Virgin Galactic will be able to fly the platform to customers’ centers of operation, rather than them have to transport satellites to fixed launch positions. “LauncherOne in its most typical configuration will be capable of delivering on the order of 500 lb (225 kg) to low inclination Low Earth Orbit,” Virgin Galactic says, “and 225 lb (100 kg) to a higher altitude, Sun-Synchronous Low Earth Orbit. Other configurations may offer significantly greater performance.”

Scientists confirm existence of dark galaxies

It’s been believed for some time that there are “dark galaxies” in the universe, gas-rich clusters that don’t have any stars. Until now such galaxies have never been seen, but thanks to the use of the ESO’s Very Large Telescope, the first dark galaxies may have been sighted. Since they’re devoid of stars, very little light is emitted from the galaxies, although they’ve been spotted by the illumination of nearby quasars.

This is the first time that the dark galaxies have been directly observed, previously theorized to be be a part of general galaxy formation by feeding gas to those galaxies with stars. Simon Lilly, a researcher at the ETH Zurich University, says, “We searched for the fluorescent glow of the gas in dark galaxies when they are illuminated by the ultraviolet light from a nearby and very bright quasar. The light from the quasar makes the dark galaxies light up in a process similar to how white clothes are illuminated by ultraviolet lamps in a night club.”

Using the sensitivity of the Very Large Telescope, the team that made the discovery took advantage of a series of long exposures to detect the faint glow of the galaxies. Sebastiano Cantalupo, the lead author behind the study from the University of California, says the plan eventually reaped rewards: “After several years of attempts to detect fluorescent emission from dark galaxies, our results demonstrate the potential of our method to discover and study these fascinating and previously invisible objects.”

Other information was also taken away from the study. The mass of the gas in the galaxies is said to be over one billion times of what’s found in the Sun. The star formation efficiency has also been suppressed over 100 times that of typical galaxies.

Researchers find space travel prolongs the life of worms

Worm research suggests space travel could prolong life

We’ve seen research that suggests prolonged space travel could have some adverse effects on the human body, but it looks like there could be some real benefits as well. As BBC News reports, a new study conducted on Caenorhabditis elegans worms sent to the International Space Station has revealed evidence that the trip to space actually slowed their aging process. Specifically, researchers from the University of Nottingham and others institutions part of the ICE-First project found that the time in space reduced activity in a group of genes that have been shown to prolong the worms’ lifespan when suppressed on earth. Of course, these are worms we’re talking about, but this particular species is often used for such research due to its biological similarities to humans, so the discovery could well lead to more insight into how we age in space as well. Those curious can find the full paper linked below.

Waldo Canyon Fire scar viewed from space

What you are seeing above is the scar left by the Waldo Canyon Fire that ravaged 18,274 acres of land and destroyed nearly 350 homes, killing two people and forcing at least 32,000 residents to evacuate. The photo was taken by NASA’s Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on July 4. During that day, 90 percent of the wildfire had been already contained. The red color represents the land covered by vegetation while the brown color reveals the exact coverage area of the wildfire. Light brown areas represent slight burning  while the bright red patches of vegetation near Colorado Springs are golf courses, parks, and other irrigated land. The Waldo Canyon Fire was first reported on June 23, 2012 and it is considered as the most destructive wildfire to ever hit Colorado. The Denver Post estimates that the total damages caused by the wildfire could go up to more than $110 million.

Study reveals space travel may slow ageing process

Researchers may have just cracked the code for living longer. Several Caenorhabditis elegans worms, which surprisingly have a lot in common with humans, were taken onboard an 11-day mission to the International Space Station and brought back to be studied. The C. elegans worm is one of the most studied organisms in the entire world and is frequently used in space travel research due to the similarities they share with humans in the way muscles deteriorate.

The study revealed that five genes in the worm showed reduced activity, which actually changed how they aged. When these genes were supressed in Earth-bound worms, longer lifespans would result. University of Nottingham researcher Dr. Nathaniel Szewczyk commented on the study, saying: “It would appear that these genes are involved in how the worm senses the environment and signals changes in metabolism in order to adapt to the environment. Most of us know that muscle tends to shrink in space.”

The results suggest that the worms’ response is adaptive rather than pathological. The worms also experienced changes in muscles that involved decreased production of the polyglutamine aggregates protein, which plays a role in the ageing of the muscle. On that note, Szewczyk also said: “Counter-intuitively, muscle in space may age better than on Earth. It may also be that spaceflight slows the process of ageing.”

NASA releases Greely Panorama video from Mars

I really love it NASA releases new photos and video taken by various spacecraft, and rovers on the surface of other planets. I mentioned last week that the Mars rover Opportunity had taken a bunch of new photos that NASA had released. Today comes a new video from the surface of Mars taken by the Mars Exploration Rover Opportunity.

The full circle scene was pieced together into one seamless panoramic view by combining 817 images taken by Opportunity’s Pancam. The panoramic photos were shot while Opportunity sat waiting out the Martian winter. Opportunity sat still for four months during the winter.

Opportunity was conducting some sort of work while sitting still, presumably other than taking these photos. It’s interesting that the solar panels in some of the early scenes appear to have a very thick coating of Martian dust. Ultimately, Opportunity will be unable to gather enough power from the sun to sustain itself if the dust on the panels becomes too thick.
