CAPE CANAVERAL, Fla – A NewSpace company based out of New Port Richey in Florida is working to provide suborbital access to space for firms with scientific payloads. The Star Lab project is an experimental suborbital launcher, designed to provide frequent, less expensive access to sub-orbit. This could allow educational and scientific institutions across the nation to conduct experiments that would normally be impractical.
“If Star Lab proves itself viable, as we feel it will, this could open the door to a great many scientific institutions conducting their research by using the Star Lab vehicle,” said Mark Homnick the CEO of 4Frontiers Corporation.

4Frontiers is working to launch their Star Lab sounding rocket vehicle into sub-orbital space via an F-104 Starfighter that is part of the Starfighters demo team based out of Kennedy Space Center. 4Frontiers hopes to launch a prototype early next year with commercial flights to follow about six months later.
On Thursday Oct. 27, Star Lab began the first of its tests as it was mounted to a F-104 Starfighter and the aircraft then conducted several fast-taxi runs up and down NASA’s Shuttle Landing Facility (SLF) with the Star Lab vehicle affixed to one of its pylons. On the last of these fast taxis, the jet aircraft deployed its drogue chute. These maneuvers were conducted to collect data to test the Star Lab vehicle’s response.
In terms of providing access to space, compared to more conventional means, the Star Lab project is considered to be an innovative and cost-effective means for scientific firms to test their experiments in the micro-gravity environment. Photo Credit: Alan Walters/awaltersphoto.com
The Star Lab suborbital vehicle is an air-launched sounding rocket, which is designed to be reusable and can reach a maximum altitude of about 120km.
The Star Lab vehicle carrying scientific payloads is launched from the venerable F-104 Starfighter jet. After the Star Lab payload stage reaches its predetermined altitude, it will descend by parachute into the Atlantic Ocean off the coast of Florida. Star Lab is capable of carrying up to 13 payloads per flight.

All of these payloads will have access to the outside, sub-orbital space environment. One payload on each mission will be deployable by way of an ejectable nosecone on the Star Lab vehicle. 4Frontiers Corporation will handle integrating the payloads into the vehicle. After the craft splashes down, private recovery teams will collect and return it to 4Frontiers. It in turn will have the payloads off-loaded and the Star Lab vehicle will then be reprocessed for its next mission.
“Today, 4Frontiers and Starfighters, with the assistance of the Florida Space Grant Consortium, unveiled to the public for the first time the Star Lab suborbital project. Star Lab is an air-launched reusable sounding vehicle, built using COTS (Commercial Off The Shelf) technology and able to reach altitudes of up to 120km,” said 4Frontiers’ Business Development Manager Panayot Slavov. “With its very reasonable price structure, frequent flight schedule and numerous educational and research opportunities, the vehicle and the project will turn into the suborbital research platform of choice for all those who are interested in experimenting and learning about suborbital space.”
The project was created through a cooperative agreement between the 4Frontiers Corporation, Starfighters Aerospace, Embry-Riddle Aeronautical University and the University of Central Florida with funding provided by the NASA Florida Space Grant Consortium.

A new 4-part mini-series debuts tonight on PBS station in the US, featuring theoretical physicist Brian Greene. The series is called “Fabric of the Cosmos” and is based on Greene’s 2004 book of the same name. It premieres tonight (Nov. 2, 2011) on NOVA, with subsequent episodes airing November 9, 16 and 23. The series will probe the most extreme realms of the cosmos, from black holes to dark matter, to time bending and parallel realities.

It’s been a tenet of the standard model of physics for over a century. The speed of light is a unwavering and unbreakable barrier, at least by any form of matter and energy we know of. Nothing in our Universe can travel faster than 299,792 km/s (186,282 miles per second), not even – as the term implies – light itself. It’s the universal constant, the “c” in Einstein’s E = mc2, a cosmic speed limit that can’t be broken.
That is, until now.
An international team of scientists at the Gran Sasso research facility outside of Rome announced today that they have clocked neutrinos traveling faster than the speed of light. The neutrinos, subatomic particles with very little mass, were contained within beams emitted from CERN 730 km (500 miles) away in Switzerland. Over a period of three years, 15,000 neutrino beams were fired from CERN at special detectors located deep underground at Gran Sasso. Where light would have made the trip in 2.4 thousandths of a second, the neutrinos made it there 60 nanoseconds faster – that’s 60 billionths of a second – a tiny difference to us but a huge difference to particle physicists!
The implications of such a discovery are staggering, as it would effectively undermine Einstein’s theory of relativity and force a rewrite of the Standard Model of physics.

“We are shocked,” said project spokesman and University of Bern physicist Antonio Ereditato.
“We have high confidence in our results. We have checked and rechecked for anything that could have distorted our measurements but we found nothing. We now want colleagues to check them independently.”
Neutrinos are created naturally from the decay of radioactive materials and from reactions that occur inside stars. Neutrinos are constantly zipping through space and can pass through solid material easily with little discernible effect… as you’ve been reading this billions of neutrinos have already passed through you!
The experiment, called OPERA (Oscillation Project with Emulsion-tRacking Apparatus) is located in Italy’s Gran Sasso facility 1,400 meters (4,593 feet) underground and uses a complex array of electronics and photographic plates to detect the particle beams. Its subterranean location helps prevent experiment contamination from other sources of radiation, such as cosmic rays. Over 750 scientists from 22 countries around the world work there.
Ereditato is confident in the results as they have been consistently measured in over 16,000 events over the past two years. Still, other experiments are being planned elsewhere in an attempt to confirm these remarkable findings. If they are confirmed, we may be looking at a literal breakdown of the modern rules of physics as we know them!
“We have high confidence in our results,” said Ereditato. “We have checked and rechecked for anything that could have distorted our measurements but we found nothing. We now want colleagues to check them independently.”
A preprint of the OPERA results will be posted on the physics website ArXiv.org.
Universe Today: You’ve been really busy, with writing books, filming two television series and DVDs. Do you have time to do research in particle physics as well?
Brian Cox: Well, I must say I’ve been a bit restricted over the past couple of years in how much research I’ve done. I’m still attached to the experiment at CERN, but it’s just one of those things! In many ways it’s a regret because I would love to be there full time at the moment because it is so genuinely exciting. We’re making serious progress and we’re going to discover something like the Higgs particle, I would guess, within the next 12 months.
But then again, you can’t do everything and it’s a common regret amongst academics, actually, that that as they get older, they get taken away from the cutting-edge of research if they’re not careful! But I suppose it is not a bad way to be taken away from the cutting edge, to make TV programs and push this agenda that I have to make science more relevant and popular.
UT : Absolutely! Outreach and educating the public is very important, especially in the area of research you are in. I would guess a majority of the general public are not exceptionally well-versed in particle physics.
Cox: Well, Carl Sagan is a great hero of mine and he used to say it is really about teaching people the scientific method – or actually providing the understanding and appreciation of what science is. We look at these questions, such as what happened just after the Universe began, or why the particles in the Universe have mass – they are very esoteric questions.
But the fact that we’ve been able build some reasonable theories about the how old universe is — and we have a number 13.73 ± 0.12 billion years old, quite a precise number — so the question of showing how you get to those quite remarkable conclusions is very important. When you look at what we might call more socially-important subjects – for example how to respond to global warming, or what should be our policy for vaccinating the population against disease, or how should we produce energy in the future, and if you understand what the scientific method is and that it is apolitical and a-religious and it is a-everything and there is no agenda there, and is just pure way of looking of universe, that’s the important thing for society to understand.
“Wonders of the Universe” is a book about the television series. Traditionally these books are quite ‘coffee table,’ image-heavy books. The filming of the series took longer than we anticipated, so actually the book got written relatively quickly because I had time to sit down and really just write about the physics. Although it is tied with the television series, it does go quite a lot deeper in many areas. I’m quite pleased about that. So it’s more than just snapshots of my view of the physics of the TV series.
I should say also, some parts of it are in the form of a diary of what it was like filming the TV series. There are always some things you do and places you go that have quite an impact on you. And I tend to take a lot of pictures so many of the photographs in the book are mine. So, it is written on two levels: It is a much deeper view of the physics of the television series, but secondly it is a diary of the experience of filming the series and going to those places.
(Editor’s note, Cox is also just finishing a book on quantum mechanics, so look for that in the near future)

UT : What were some of your best experiences while filming ‘Wonders?’
Cox: One thing that, well, I wouldn’t say enjoyed filming, because it was quite nerve-wracking – but something that really worked was the prison demolition sequence in Rio. We used it as an analog for a collapsing star, a star at the end of its life that has run out of fuel and it collapses under its own gravity. It does that in a matter of seconds, on the same timescale as a building collapses when you detonate it.
Wandering around a building that is full of live dynamite and explosives is not very relaxing! It was all wired up and ready to go. But when we blew it up, and I thought it really worked well, and I enjoyed it a lot, actually as a television piece.
The ambition of the series is to try and get away from using too many graphics, if possible. You obviously have to use some graphics because we are talking about quite esoteric concepts, but we tried to put these things ‘on Earth’, by using real physical things to talk about the processes. What we did, we went inwards into the prison and at each layer we said, here’s where the hydrogen fuses to helium, and here’s the shell where helium goes to carbon and oxygen, and another shell all the way down to iron at the center of the stars. That’s the way stars are built, so we used this layered prison to illustrate that and then collapse it. That’s a good example of what the ambition of the series was.
UT : You’ve been called a rock star in the physics and astronomy field but in actuality you did play in a rock band before returning to science. What prompted that shift in your career?
Cox: I always wanted to be a physicist or astronomer from as far back as I can remember, that was always my thing when I was growing up. I got distracted when I was in my teens, or interested I should say, in music and being in a band. The opportunity came to join a band that was formed by an ex-member of Thin Lizard, a big rock band in the UK, and the States as well, so I did that. We made two albums; we toured with lots of people. That band split up and I went to university and then joined another band as a side line, and that band got successful as well. That was two accidents, really! It was a temporary detour rather than a switch, because I always wanted to do physics.
UT : Thanks for taking the time to talk with us on Universe Today – we appreciate all the work you do in making science more accessible so everyone can better appreciate and understand how it impacts our lives.
A new opportunity is available to students to have their experiments flown to the ISS. Credit: NAS

A new opportunity is available for students and teachers to be part of history and fly the very first Student Spaceflight Experiments Program (SSEP) mission to the International Space Station. This program is open to students from any country that is part of the ISS partnership, in grades 5-12 as well as colleges and universities.
This opportunity offers real research done on orbit, with students designing and proposing the experiments to fly to the space station.
“Science is not something that can only be carried out by an elite community of researchers,” Dr. Jeff Goldstein, the Director for the National Center for Earth and Space Science Education told Universe Today. “It’s really just organized curiosity, and can be undertaken by anyone. So to inspire our next generation of scientists and engineers, we thought we’d give students an opportunity to do real scientific research on America’s newest National Laboratory – the International Space Station.”
SSEP is a program that launched in June 2010 by the National Center for Earth and Space Science Education in partnership with NanoRacks, LLC, a company that is working with NASA under a Space Act Agreement as part of the utilization of the International Space Station as a National Laboratory.
Two previous SSEP missions flew on the final shuttle flights, but this is the first to be part of the ISS science program.
NanoRacks hopes to stimulate space station research by providing a very low-cost 1 kilogram platform and other hardware that puts micro-gravity projects within the reach of universities and small companies, as well as elementary and secondary schools through SSEP. So, this is actually a commercial space program and not a NASA program.
On the previous SSEP missions with the space shuttles, 1,027 student team proposals were submitted with 27 experiments selected to fly, representing the 27 communities.
“We know even 5th graders can rise to this challenge and amaze us all,” Goldstein said, “and they already proved it on the final two flights of the Space Shuttle.”
The countries that can participate are the US, Canada, Japan and the European nations that are partners in the ISS program.
SSEP Mission 1 to ISS is now open for registration, with participating communities selected no later than September 30, 2012, so this is time critical.
Goldstein noted there are a significant number of resources that make this process straight-forward, including an instructionally designed recipe allowing teachers to easily facilitate the introduction of the program in the classroom, conduct experiment design, and do the proposal writing.
There are five categories of participation:
Pre-College (the core focus for SSEP) in the U.S., (grades 5-12), with a participating school district—even an individual school—providing stunning, real, on-orbit RESEARCH opportunities to their upper elementary, middle, and high school students
2-Year Community Colleges in the U.S., (grades 13-14), where the student body is typically from the local community, providing wonderful pathways for community-wide engagement
4-Year Colleges and Universities in the U.S., (grades 13-16), with an emphasis on Minority-Serving Institutions, where the program fosters interdisciplinary collaboration across schools and departments, and an opportunity for formal workforce development for science majors
Communities in the U.S. led by Informal Education or Out-of-School Organizations, (e.g., a museum or science center, a homeschool network, a boy scout troop), because high caliber STEM education programs must be accessible to organizations that promote effective learning beyond the traditional classroom
Communities in ISS Partner Nations: EU nations, Canada, and Japan with participation through NCESSE’s Arthur C. Clarke Institute for Space Education.
Goldstein said the program is a U.S. national Science, Technology, Engineering, and Mathematics (STEM) education initiative that gives up to 3,200 students across a community—middle and high school students (grades 5-12), and/or undergraduates the ability to fly their own experiments in low Earth orbit on the International Space Station.
A replication of the arsenic life experiment being done by biologist Rosie Redfield. Image credit: Rosie Redfield.
[/caption]
One of the most vocal and ardent critics of the so-called ‘arsenic life’ experiment which was published in December 2010 was biologist Rosie Redfield from the University of British Columbia in Vancouver. The science paper by NASA astrobiologist Felisa Wolfe-Simon and her team reported that a type of bacteria in Mono Lake in California can live and grow almost entirely on arsenic, a poison, and incorporates it into its DNA. Redfield called the paper “lots of flim-flam, but very little reliable information.” Her opinion was quickly seconded by many other biologists/bloggers.
Redfield has been working on replicating the experiment done by Wolfe-Simon, and doing in her work in front of the world, so to speak. She is detailing her work in an open lab notebook on her blog. So far, she reports that her results contradict Wolfe-Simon et al.’s observations.
To date, Redfield is finding that the bacteria, called GFAJ-1, is not living and growing in arsenic, but dying. Redfield says her work refutes that cells from the GFAJ-1 could use arsenic for growth in place of phosphorus, and when arsenic was added to the low-phosphorus medium in which the bacteria was living, the bacteria was killed. Additionally, in other test viles, the growth properties Redfield is finding for GFAJ-1 don’t match those reported by Wolfe-Simon and her team, which claimed that the bacteria could not grow on a low concentration of phosphorus, and that the bacteria could grow on arsenic in the absence of phosphorus.
Redfield’s two major early criticisms of the original paper were that the authors had not ruled out the possibility that the bacteria were feeding on phosphorus contaminating their growth medium; and that the bacterial DNA was not properly purified, so that the arsenic detected might not actually have been in DNA.
An article in Nature reports that other researchers also working on replicating the experiment with GFAJ-1 laud Redfield’s efforts, but say it is too early to conclude that she has debunked the original work.
Additionally, one problem is that Redfield she did not replicate the experiment exactly, as she had to add one nutrient not used by the authors of the original arsenic life paper in order for the bacteria to grow.
This is not the first time scientists have written open notebooks during the replication of controversial findings, but it might be one of the more notable, given the amount of media attention the arsenic life paper received.
Redfield is also hoping that her work will highlight the benefits of open notebook-type research.
Seeing the Northern or Southern Lights is an awe-inspiring experience, but do you know the science behind their beauty? This video from Per Byhring and the physics department at the University of Oslo explains how particles originating from deep inside the core of the Sun creates aurorae in the atmosphere of Earth.
The video takes a look at how cloud of electrically charged particles emanate from the Sun, and what happens when this plasma reaches the Earth and interacts with the planet’s magnetic field, which creates fantastic light shows in the extreme northern and southern latitudes.
As a part of NASA’s ongoing Year of the Solar System – which is actually a single Martian year long, or 23 months – the excitement of planetary exploration is being brought to people around the world through a enthusiastic science outreach program called From Earth to the Solar System (FETTSS). A continuation of the well-received International Year of Astronomy 2009 From Earth to the Universe program, FETTSS provides over 90 beautiful high-resolution images of fascinating locations around our solar system; from the ice geysers of Enceladus to the plasma arcs of solar prominences, the cold dunes of Mars to the hot springs of Yellowstone, the FETTSS collection showcases many wonders of many worlds – and helps bring them within view of as many people as possible.
The images are displayed in public locations, hosted by organizations that raise all the necessary funding to have them printed and installed. The FETTSS site exists to provide the high-resolution print images as well as offer guidance as to how to best plan, market and set up an installation.
What’s wonderful about From Earth to the Solar System – as well as its predecessor From Earth to the Universe – is how it brings the fascination of science and astronomy to people who may not have previously given it much thought. By presenting large-format images with descriptive captions in common places – such as in an airport or outside in a public park – FETTSS hosts are actively capturing the interest of viewers and engaging them in astronomy – many undoubtedly for the first time.
People around the world are being connected with the most recent work of scientists and researchers in a way that’s attractive, informative and yet accessible. This is the key to any successful outreach program.
The images are at once artistic and informative, weaving together themes in astrobiology, planetary science, and astronomy. Including contributions from backyard astronomers, large telescopes in space, and even point-and-shoot cameras of field researchers, the collection represents the current state of exploration as seen through the eyes of the scientific community.
Currently an exhibit is just wrapping up in Corpus Christi, Texas, at the Museum of Science and History and was very well-received by both people and the press! The next scheduled event will take place in June at the National Air and Space Museum in Washington, DC.
A FETTU outdoor installation in Geneva
FETTSS looks to build on the success of the 2009 FETTU program.
“We are hoping to replicate some of FETTU’s success and bring a measure of sustainability to the FETTU concept. ‘From Earth to the Solar System’ is taking a similar grassroots-type of approach to exhibit creation, and will hopefully help remove the barrier to ‘seeking science out’ for some visitors and help make setting up an exhibit more efficient for organizers,” said Kimberly Kowal Arcand, Media Production Coordinator for the Harvard-Smithsonian Center for Astrophysics and FETTSS principal investigator.
“With FETTU – and what we hope to find with FETTSS – there was a wonderful response from both visitors and organizers,” said Arcand. “We found, unexpectedly, a sort of emotional and personal connection to the images in the FETTU project and I’m interested to see if we find that again with FETTSS. I was personally overwhelmed with the response to FETTU… it was the most inspiring thing I have ever worked on!”
Already, exhibitors worldwide have expressed interest in hosting FETTSS installations… from Argentina, Serbia, China, Colombia, Canada, UK, Ireland, Egypt, Spain, Armenia, as well as from numerous locations in the US – many of whom had previously hosted FETTU events.
So with such a great program and strong response, the question remains: what’s next?
“From Earth to the Sun? From Earth to the Galaxies?” suggested Arcand.
With all that’s being discovered, whatever it is it’s sure to be another success!

Dude! This awesome image looks like a psychedelic 1970’s flashback. But is is actually a droplet of fuel burning in space, on board the International Space Station. NASA explains that because of the absence of gravity, fuels burning in space behave very differently than they do on Earth. The Flame Extinguishing Experiment on board the ISS is examining the combustion of such liquid fuel droplets, and in this image, a 3-millimeter diameter droplet of heptane fuel burns in microgravity, producing soot. When a bright, uniform backlight is placed behind the droplet and flame and recorded by a video camera, the soot appears as a dark cloud. Image processing techniques can then quantify the soot concentration at each point in the image.
NASA explains:
This colorized gray-scale image is a composite of the individual video frames of the backlit fuel droplet. The bright yellow structure in the middle is the path of the droplet, which becomes smaller as it burns. Initial soot structures (in green) tend to form near the liquid fuel. These come together into larger and larger particles which ultimately spiral out of the flame zone in long, twisting streamers.

Think again if you believe the suborbital space market is exclusively for well-heeled tourists. The Southwest Research Institute has just inked deals with Virgin Galactic and XCOR Aerospace to fly up to 17 scientific research flights. Three scientists, including Dr. Alan Stern, former head of the Science Mission Directorate at NASA and current New Horizons Principal Investigator, will become some of the first scientists to fly on a commercial spacecraft to conduct scientific research. They will fly on board Virgin’s SpaceShipTwo and XCOR’s Lynx.
“We’re another step closer to the era of routine ‘field work’ in space research,” said Dr. Dan Durda, another SwRI scientist who is scheduled to fly. “More and more researchers will soon fly with their own experiments in space, and do it regularly enough to allow the important advances that come with iterative investigations. I’m looking forward to that future and helping it become a reality.”
“We at SwRI are very strong believers in the transformational power of commercial, next-generation suborbital vehicles to advance many kinds of research,” said Stern. “We also believe that by putting scientists in space with their experiments, researchers can achieve better results at lower costs and a higher probability of success than with many old-style automated experiments.”

The spacecraft will fly on short suborbital flights to altitudes greater than 107,000 meters (350,000 feet) above the internationally recognized boundary of space.
At least two SwRI researchers will fly on SpaceShipTwo, which can carry two pilots and up to six researchers, and later, there will be a dedicated six-seat research mission SS2. SpaceShipTwo’s large cabin enables researchers to work together in an “out-of-seat” micro gravity environment.

SwRI researchers will also fly at least six high altitude missions aboard XCOR Corporation’s Lynx Mark I high-altitude rocket plane, which carries a pilot and a single researcher at altitudes up to 200,000 feet. Lynx I is currently in development, with test flights expected to begin in 2012.
The types of research planned includes biomedical, microgravity and astronomical imaging experiments.
Besides Stern andDurda, Dr. Cathy Olkin is also scheduled to fly on the research flights. All three scientists selected have trained for suborbital spaceflight aboard zero-G aircraft, in NASTAR centrifuges and aboard Starfighter F-104 jet fighters in the last year.
“This is a historic moment for spaceflight,” said Commercial Spaceflight Federation Executive Director John Gedmark. “A scientific research institution is spending its own money to send its scientists to space. I expect that these scientists will be the first of many to fly to space commercially. As the scientific community realizes that they can put payloads and people into space at unprecedented low costs, the floodgates will open even wider.”
