Neil Armstrong — the first man on the moon, who died in 2012 — will now be the namesake of one of NASA’s research centers. A new law designated the Armstrong Flight Research Center took effect March 1, replacing the old name since 1976, the Dryden Flight Research Center.
Former NASA deputy administrator Hugh L. Dryden will still see his name in the area, however, as the center’s 12,000-square-mile (31,000-square-kilometer) Western Aeronautical Test Range is now called Dryden Aeronautical Test Range.
“I cannot think of a more appropriate way to honor these two leaders who broadened our understanding of aeronautics and space exploration,” stated NASA administrator Charles Bolden.
“Both Dryden and Armstrong are pioneers whose contributions to NASA and our nation still resonate today. Armstrong was the first person to walk on the moon. Dryden’s expertise at the National Advisory Committee for Aeronautics and then at NASA established America’s leadership in aerospace, and his vision paved the way for Armstrong to take those first steps.”

At the center, Armstrong is probably best remembered for his flights in the X-15, a rocket-powered aircraft that set several altitude and speed records in the 1960s. At what was then the NACA High-Speed Flight Station, he flew seven times in that particular experimental aircraft, along with 41 other kinds of aircraft, between 1955 and 1962. Armstrong was also involved with development of a predecessor to a lunar landing training vehicle used in the Apollo missions (which almost killed Armstrong in a practice run for Apollo 11).

Armstrong’s connection with the research center continued after he left the astronaut corps, when he was NASA’s deputy associate administrator for aeronautics. In this capacity, NASA wrote, he was “overseeing aeronautical research programs being conducted at the center, particularly its pioneering work on developing digital electronic flight control systems.”
The center is located on California’s Edwards Air Force Base. Renaming was directed in legislation authored by Rep. Kevin McCarthy (R) of California’s 22nd district (and also the house majority whip), NASA stated. After the bill passed the U.S. House of Representatives in 2013 and the Senate in January, President Barack Obama signed the name into law Jan. 16. A renaming ceremony is expected in the spring.
Armstrong is the second astronaut to have a center named after him. The Lewis Research Center in Cleveland was renamed Glenn Research Center after Sen. John Glenn (D) in 1999. Glenn flew twice in space. In 1962, Glenn became the first American to orbit the Earth. He then returned to space in 1998 at the age of 77, becoming the oldest person to fly in space to date.
We all know what a big rocket launch looks like from the ground, but this is what it looks like from above the ground — 260 miles above the ground! The photo above was captured from the Space Station earlier today by NASA astronaut Rick Mastracchio, and it shows the contrail from a heavy-lift Ariane 5 that had just launched from ESA’s spaceport on the French Guiana coast: flight VA217, Arianespace’s milestone 250th launch carrying the ABS-2 and Athena-Fidus satellites into orbit.
Rick shared his view on Twitter with his nearly 39,000 followers, and now less than an hour later, we’re sharing it here. (Isn’t technology wonderful?)
For a more “natural” look, here it is reversed:

The ISS was in the process of passing over Costa Rica when the image was taken. The rocket launched from Kourou, French Guiana — about 2,175 miles (3,500 km) away. What a view!
For this and more great images from orbit follow Rick on Twitter @AstroRM.
Watch a video of the VA217 launch below:
The 250th launch performed by Arianespace lifted off from ESA’s spaceport in French Guiana, delivering a dual-satellite payload into geostationary transfer orbit: ABS-2 for global satellite operator ABS, and Athena-Fidus for the defense/homeland security needs of France and Italy. The flight lasted just over 32 minutes. (Source)
There’s an old Chinese proverb that says, “May you live in interesting times,” and 2013 certainly fit the bill in the world of spaceflight and space science. The past year saw spacecraft depart for Mars, China land a rover on the Moon, and drama in low Earth orbit to repair the International Space Station. And all of this occurred against a landscape of dwindling budgets, government shutdowns that threatened launches and scientific research, and ongoing sequestration.
But it’s a brave new world out there. Here are just a few space-related stories that we’ll watching in 2014:

Rosetta to Explore a Comet: On January 20, 2014, the European Space Agency will hail its Rosetta spacecraft and awaken it for its historic encounter with comet 67P/Churyumov-Gerasimenko later this year in August. After examining the comet in detail, Rosetta will then dispatch its Philae lander, equipped complete with harpoons and ice screws to make the first ever landing on a comet. Launched way back in 2004, Rosetta promises to provide the cosmic encounter of the year.

A1 Siding Springs vs. Mars: A comet discovery back in 2013 created a brief stir when researchers noted that comet C/2013 A1 Siding Springs would make a very close passage of the planet Mars on October 19th, 2014. Though refinements from subsequent observations have effectively ruled out the chance of impact, the comet will still pass 41,300 kilometres from the Red Planet, just outside the orbit of its outer moon Deimos. Ground-based observers will get to watch the +7th magnitude comet close in on Mars through October, as will a fleet of spacecraft both on and above the Martian surface.
A recent tweet from @NewHorizons_2015, a spacecraft that, ironically, launched just weeks before Twitter in 2006.
Spacecraft En Route to Destinations: Though no new interplanetary missions are set to depart the Earth in 2014, there are lots of exciting missions currently underway and headed for worlds yet to be explored. NASA’s Dawn spacecraft is headed towards its encounter with 1 Ceres in February 2015. Juno is fresh off its 2013 flyby of the Earth and headed for orbital insertion around Jupiter in August 2016. And in November of this year, New Horizons will switch on permanently for its historic encounter with Pluto and its retinue of moons in July 2015.
LUX & the Hunt for Dark Matter: It’s all around us, makes up the bulk of the mass budget of the universe, and its detection is THE name of the game in modern astrophysics. But just what is dark matter? Some tantalizing– and hotly contested –data came out late last year from of an unusual detector deep underground near Lead, South Dakota. The Large Underground Xenon experiment (LUX) looks for Weakly Interacting Massive Particles (WIMPs) interacting with 370 kilograms of super-cooled liquid Xenon. LUX requires its unique locale to block out interference from incoming cosmic rays. LUX is due to start another 300 day test run in 2014, and the experiment will add another piece to the puzzle posed by dark matter to modern cosmology, whether or not detections by LUX prove to be conclusive.

The Hunt for Gravity Waves: Another story to watch may come out of Caltech’s twin gravity wave observatories when its Advanced LIGO system goes online later this year. Established in 2002, the Laser Interferometer Gravitational-Wave Observatory (LIGO) is comprised of two detectors: one in Hanford Washington and one outside of Livingston, Louisiana. The detectors look for gravity waves generated by merging binary pulsars and black holes. Though no positive detections have yet been made, Advanced LIGO with boast ten times the sensitivity and may pave the way for a new era of gravitational wave astronomy.

Spacecraft reach Mars: 2014 is an opposition year for the Red Planet, and with it, two new missions are slated to begin operations around Mars: India’s Mars Orbiter Mission (MOM) also known as Mangalyaan-1 is slated to enter orbit on September 24th, and NASA’s MAVEN or Mars Atmosphere and Volatile Evolution Mission is set to arrive just 2 days earlier on September 22nd. MOM and MAVEN will join the Curiosity and Opportunity rovers, ESA’s Mars Express, NASA’s Odyssey spacecraft and the Mars Reconnaissance Orbiter in the quest to unlock the secrets of the Red Planet.
Space Tourism Takes Off: Virgin Galactic’s SpaceShipTwo passed a key milestone test flight in late 2013. Early 2014 may see the first inaugural flights by Virgin Galactic out of the Mohave Spaceport and the start of sub-orbital space tourism. SpaceShipTwo will carry two pilots and six passengers, with seats going for $250,000 a pop. Hey, room for any space journalists in there? On standby, maybe?
The First Flight of Orion: No, it’s not the first flight of the proposed sub-light interplanetary spacecraft that was to be propelled by atomic bombs… but the September launch of the Orion Multi-Purpose Crew Vehicle is the first step in replacing NASA’s capability to launch crews into space. Exploration Flight Test 1 (EFT-1) will be a short uncrewed flight and test the capsule during reentry after two orbits. It’s to be seen if the first lunar orbital mission using an Orion MPCV will occur by the end of the decade.

The First Flight of the Falcon Heavy: 2014 will be a busy year for SpaceX, starting with the launch of Thaicom-6 out of Cape Canaveral this Friday on January 3rd. SpaceX is now “open for business,” and expect to see them conducting more satellite deployments for customers and resupply missions to the International Space Station in the coming year. They’ll also be moving ahead with tests of their crew-rated version of the Dragon capsule in 2014. But one of the most interesting missions to watch for is the demo flight of the Falcon 9 Heavy slated to launch out of Vandenberg Air Force Base by the end of 2014.… more to come!
The Sunjammer Space Sail: An interesting mission moves in 2014 towards a January 2015 launch: LGarde’s Sunjammer solar sail. Sunjammer will test key solar sail technologies as well as deliver the Solar Wind Analyzer (SWAN) and the MAGIC Magnetometer to the L1 Earth-Sun Lagrange point. Sunjammer will launch on a Falcon-9 rocket and deploy a 1200 square metre solar sail weighing only 32 kilograms. This will be a great one for ground satellite-spotters to track as well as it heads out!
Gaia Opens for Business: Launched on a brilliant night-shot out of the Kourou Space Center in French Guiana on December 19th of last year, the European Space Agency’s Gaia space observatory will begin its astrometry mission in 2014, creating most accurate map yet constructed of our Milky Way Galaxy. But we also anticipate exciting new discoveries due to spin-offs from this mission, to include the discovery of new exoplanets, asteroids, comets and much more.
And as in years previous, the quest to explore brave new worlds will be done against the backdrop of tightening budgets. Just like in household budgets, modern spaceflight is a continual conflict between what we would wish and what we can afford. In recent years, no mission seems to be safe, and there have even been occasional congressional rumblings to pull the plug on missions already underway. Interesting times, indeed… 2014 promises to be an extraordinary time in spaceflight and space science, both on Earth and beyond.
Another blow was dealt to deep space exploration this past weekend. The announcement comes from Jim Green, NASA’s Planetary Science Division Director. The statement outlines some key changes in NASA’s radioisotope program, and will have implications for the future exploration of the outer solar system.

No more falling asleep before takeoff during those boring safety presentations – at least on Virgin America Airlines. Delta Airlines previously made their safety presentation a bit more interesting (see below) but Virgin has taken the presentation to new heights, turning the video into a song and dance, literally, with the help of dance stars like Todrick Hall and Madd Chadd.
No, this isn’t The Onion… as a concerned consumer of all that is space news, you have indeed arrived at the cyber-doorstep of Universe Today.
I’ll admit though, that we did do a double take about a week back when a peculiar claim came our way via the Iranian Space Agency. Yes, there is an Iranian Space Agency, and it’s kind of frightening that they remain open for business while NASA is largely shutdown.
In mid-September, senior Iranian space program official Mohammad Ebrahimi issued a statement that Iran will attempt another bio-capsule launch “within 45 days”. The unwilling occupant: a Persian cat.
Apparently, a rabbit, a mouse, and another “Space Monkey” were also in the running. Iran’s space program is shrouded in secrecy, and most launches are only announced after they’ve been conducted. This is a convenient political strategy for hiding launch failures that harkens back to the early days of the Cold War. You’re right in guessing that the Iranian Space Agency probably won’t hold a Tweetup for this one. Many western analysts see the Iran’s space effort as a thinly veiled attempt to develop its long range ballistic missile technology. Along with Israel, Iran remains the only Middle Eastern country with the proven technology to conduct indigenous satellite launches.
Iran has stated that it hopes to put an astronaut in orbit by 2019. The Pishgam (or “Pioneer” in Farsi) 2 bio-capsule launch could occur from a mobile launcher at Semnan Space Center as early as October 15th. Satellite sleuths are also expecting activity at Semnan to pick up this month, with the possible launch of SharifSat atop a Safir 1-B rocket, and Iran’s Toulou satellite aboard a rumored new launch vehicle.
Iran successfully became a space-faring nation with the launch of its 27 kilogram Omid satellite on February 2nd, 2009. It isn’t immediately clear if the upcoming launch will be an orbital launch or a sub-orbital ballistic shot. If Pisgam-2 achieves orbit, said “Space Cat” would become the first feline to circle the Earth. If recovery is attempted —again, Iran is always nebulous as to their intentions— it would also be the first time they’ve achieved a return from orbit.
But is “Space Cat” even a reality?
Iran has been caught red-handed before playing a shell game with the media in terms of its space program. Earlier this year, “Monkey-gate” erupted, as before-and-after images from the Pisgam-1 bio-capsule suborbital launch clearly showed two different monkeys before and after the flight:
Monkey business? Iran displayed a decidedly different looking monkey before, during, and after launch earlier this year! (Credit: Iran News Agency).
Clearly, Iran and other ‘Axis of Evil’ countries definitely need to sharpen their Photoshop, or at least their monkey-switching skills. Either said monkey launch never actually occurred, or (more likely), the unwilling Iranian space primate never survived the flight.
Perhaps this is why Iran decided on a feline occupant this time around, for possible ease of replacement?
PETA, the People for the Ethical Treatment of Animals, have also issued a statement concerning the impending launch of “Space Cat” by Iran, calling the action an “archaic experiment, a throwback to the primitive techniques of the 1950’s.”
NASA did entertain the idea of “Catronauts” early in the space program. (Credit: NASA).
The U.S. and the Soviet Union launched animals into space as a prelude to human spaceflight. On November 3rd, 1957, Laika the dog became the first animal to orbit the Earth. Laika perished is space due to overheating, as did several unfortunate monkeys that were launched on the first US ballistic tests.
Russia still conducts the occasional launch of animals into space, including the Bion-1M “Space Zoo” mission earlier this year. The Bion missions allow for scientists to dissect the specimens afterwards to study the effects of a month in zero-g, something you can’t do with humans.
And the U.S. did once fly cats in zero-g aboard its Convair C-131 “Vomit Comet” aircraft, as can be seen in this bizarre video:
But the first cat in space was actually launched by France atop a Veronique AGI sub-orbital rocket 50 years ago this month on October 18th, 1963. It would be ironic if Iran conducted it launch this month on the anniversary! The story goes the Felix, the original cat slated for the flight, escaped just prior to launch from the Sahara desert Hammaguir test site in Algeria, and was replaced by the “backup crew,” a female cat named Felicette. Felicette survived the 15 minute flight, reaching an apogee of 217 kilometres. A follow-up launch of a second cat six days later wasn’t so lucky.

As always, Iran’s intentions for the future of its space program remain hidden. Their current launch capabilities remain limited, and are a far cry from being able to hoist a human into orbit anytime soon. If the launch of “Space Cat” does come to pass this month, it’ll be over protests from animal rights groups and the general public. Hey, didn’t the former Iranian president Mahmoud Ahmadinejad say earlier this year after “Monkey-Gate” that he was willing to be “The first Iranian to be sacrificed by the scientists of my country and go into space” as the first Iranian astronaut? Is he really going to let Space Cat upstage him?

50 million light-years away a quasar resides in the hub of galaxy NGC 4438, an incredibly bright source of light and radiation that’s the result of a supermassive black hole actively feeding on nearby gas and dust (and pretty much anything else that ventures too closely.) Shining with the energy of 1,000 Milky Ways, this quasar — and others like it — are the brightest objects in the visible Universe… so bright, in fact, that they are used as beacons for interplanetary navigation by various exploration spacecraft.
“I must go down to the seas again, to the lonely sea and the sky,
And all I ask is a tall ship and a star to steer her by.”
Deep-space missions require precise navigation, especially when approaching bodies such as Mars, Venus, or comets. It’s often necessary to pinpoint a spacecraft traveling 100 million km from Earth to within just 1 km. To achieve this level of accuracy, experts use quasars – the most luminous objects known in the Universe – as beacons in a technique known as Delta-Differential One-Way Ranging, or delta-DOR.
How delta-DOR works (ESA)
Delta-DOR uses two antennas in distant locations on Earth (such as Goldstone in California and Canberra in Australia) to simultaneously track a transmitting spacecraft in order to measure the time difference (delay) between signals arriving at the two stations.
Unfortunately the delay can be affected by several sources of error, such as the radio waves traveling through the troposphere, ionosphere, and solar plasma, as well as clock instabilities at the ground stations.
Delta-DOR corrects these errors by tracking a quasar that is located near the spacecraft for calibration — usually within ten degrees. The chosen quasar’s direction is already known extremely well through astronomical measurements, typically to closer than 50 billionths of a degree (one nanoradian, or 0.208533 milliarcsecond). The delay time of the quasar is subtracted from that of the spacecraft’s, providing the delta-DOR measurement and allowing for amazingly high-precision navigation across long distances.
“Quasar locations define a reference system. They enable engineers to improve the precision of the measurements taken by ground stations and improve the accuracy of the direction to the spacecraft to an order of a millionth of a degree.”
– Frank Budnik, ESA flight dynamics expert
So even though the quasar in NGC 4438 is located 50 million light-years from Earth, it can help engineers position a spacecraft located 100 million kilometers away to an accuracy of several hundred meters. Now that’s a star to steer her by!
Not only did NASA purposely crash a Marine helicopter today, but they also stuffed 15 crash test dummies inside for a group “crash” party and filmed the event from every angle imaginable. The crash test took place at the Langley Research Center in Hampton, Virginia and engineers dropped an old Marine CH-46E helicopter fuselage from a height of about 9 meters (30 feet), traveling at about 48 km/h (30 mph) to test improved seats and seatbelts and gather data on the odds of surviving a helicopter crash.
“We designed this test to simulate a severe but survivable crash under both civilian and military requirements,” said NASA lead test engineer Martin Annett. “It was amazingly complicated with all the dummies, cameras, instrumentation and the collaborators, but it went well.”
The fuselage hit hard, as evidenced by the video and images NASA has released. Thirteen instrumented crash-test dummies and two un-instrumented manikins had a rough ride, as did some of the 40 cameras mounted inside and outside the fuselage. Preliminary observations indicate good data collection, which will take months to analyze.

Researchers used the cameras as well as onboard computers, which data from 350 instrumentation points, to record every move of the 10,300-pound aircraft and its contents. The helicopter’s unusual black-and-white-speckled paint job — a photographic technique called full field photogrammetry — also aided in the data collection effort.
“High speed cameras filming at 500 images per second tracked each black dot, so after everything is over, we can plot exactly how the fuselage reacted structurally throughout the test,” said NASA test engineer Justin Littell.
NASA will use the results of both tests in efforts to improve helicopter performance, efficiency and safety. Researchers also want to increase industry knowledge and create more complete computer models that can be used to design better and safer helicopters.

WALLOPS ISLAND, VA – A nearly 900 pound complex payload integrated with dozens of science experiments created by talented university students in a wide range of disciplines and from all across America streaked to space from NASA’s beachside Wallops launch complex in Virginia on August 13 – just before the crack of dawn.
The RockSat-X science payload blasted off atop a Terrier-Improved Malemute suborbital sounding rocket at 6 a.m. from NASA’s Wallops Flight Facility along the Eastern Shore of Virginia.
As a research scientist myself it was thrilling to witness the thunderous liftoff standing alongside more than 40 budding aerospace students brimming with enthusiasm for the chance to participate in a real research program that shot to space like a speeding bullet.
“It’s a hands on, real world learning experience,” Chris Koehler told Universe Today at the Wallops launch pad. Koehler is Director of the Colorado Space Grant Consortium that manages the RockSat-X program in a joint educational partnership with NASA.
The hopes and dreams of everyone was flying along.
Here’s a cool NASA video of the RockSat-X Aug. 13 launch:
The students are responsible for conceiving, managing, assembling and testing the experiments, Koehler told me. Professors and industrial partners mentor and guide the students.
RockSat-X is the third of three practical STEM educational programs where the students master increasingly difficult skills that ultimately result in a series of sounding rocket launches.
“Not everything works as planned,” said Koehler. “And that’s by design. Some experiments fail but the students learn valuable lessons and apply them on the next flight.”
“The RockSat program started in 2008. And it’s getting bigger and growing in popularity every year,” Koehler explained.

The 2013 RockSat-X launch program included participants from seven universities, including the University of Colorado at Boulder; the University of Puerto Rico at San Juan; the University of Maryland, College Park; Johns Hopkins University, Baltimore, Md.; West Virginia University, Morgantown; University of Minnesota, Twin Cities; and Northwest Nazarene University, Nampa, Idaho.
We all watched as a group and counted down the final 10 seconds to blastoff just a few hundred yards (meters) away from the launch pad – Whooping and hollering as the first stage ignited with a thunderous roar. Then the second stage flash – and more yelling and screams of joy! – – listen to the video.
Moments later we saw the first stage plummeting and heard a loud thud as it crashed into the ocean just 10 miles or so offshore.

For most of the students -ranging from freshman to seniors – it was their first time seeing a rocket launch.
“I’m so excited to be here at NASA Wallops and see my teams experiment reach space!” said Hector, one of a dozen aerospace students who journeyed to Wallops from Puerto Rico.
Local Wallops area spectators and tourists told me they could hear the rocket booming from viewing sites more than 10 miles away.
Others who ‘overslept’ were awoken by the rocket thunder and houses shaking.
Suborbital rockets still make for big bangs!
The Puerto Rican students very cool experiment aimed at capturing meteorite particles in space using 6 cubes of aerogel that were extended out from the rocket as it descended back to Earth, said Oscar Resto, Science Instrument specialist and leader of the Puerto Rican team during an interview at the launch complex.
“Seeing this rocket launch was the best experience of my life,” Hector told me. “This was my first time visiting the mainland. I hope to come back again!”
Another team of 7 students from Northwest Nazarene University (NNU), Idaho aimed to investigate the durability of the world’s first physically flexible integrated chips.
“Our experiment tested the flexibility of integrated circuit chips in the cryogenic environment of space,” Prof Stephen Parke of NNU, Idaho, told Universe Today in an interview at the launch pad.
“The two year project is a collaboration with chipmaker American Semiconductor, Inc based in Boise, Idaho.”
“The chips were mechanically and electrically exercised, or moved, during the flight under the extremely cold conditions in space – of below Minus 50 C – to test whether they would survive,” Parke told me.
The 44 foot long, two stage rocket flew on a parabolic arc and a southeasterly trajectory. The 20 foot RockSat-X payload soared to an altitude of approximately 94 miles above the Atlantic Ocean.

Telemetry and science data was successfully transmitted and received from the rocket during the flight.
The payload then descended back to Earth, deployed a 24 foot wide parachute and splashed down in the Atlantic Ocean some 90 miles offshore from Wallops Flight Facility. Overall the mission lasted about 20 minutes.
A commercial fishing boat hauled in the payload and brought it back to Wallops about 7 hours later.
By 2 p.m. the RockSat-X payload was back onsite at the Wallops ‘Rocket Factory’.

And I was on-hand as the gleeful students began tearing it apart to disengage their individual experiments to begin a week’s long process of assessing the outcome, analyzing the data and evaluating what worked and what failed. See my photos.

Included among the dozens of custom built student experiments were HD cameras, investigations into crystal growth and ferro fluids in microgravity, measuring the electron density in the E region (90-120km), aerogel dust collection on an exposed telescoping arm from the rockets side, effects of radiation damage on various electrical components, determining the durability of flexible electronics in the cryogenic environment of space and creating a despun video of the flight.
Indeed we already know that not every experiment worked. But that’s the normal scientific method – ‘Build a little, fly a little’.
New students are already applying to the 2014 RockSat program. And some of these students will return next year with thoughtful upgrades and new ideas!
The launch was dedicated in memory of another extremely bright young student named Brad Mason, who tragically passed away two weeks ago. Brad was a beloved intern at NASA Wallops this summer and a friend. Brad’s name was inscribed on the side of the rocket. Read about Brad at the NASA Wallops website.

Times are getting tougher in the battle to track space debris. A key asset in the fight to follow and monitor space junk is getting the axe on October 1st of this year. United States Air Force General and commander of Air Force Space Command William Shelton has ordered that the Air Force Space Surveillance System, informally known as Space Fence will be deactivated. The General also directed all related sites across the southern United States to prepare for closure.
This shutdown will be automatically triggered due to the U.S. Air Force electing not to renew its fifth year contract with Five Rivers Services, the Colorado Springs-based LLC that was awarded the contract for the day-to-day management of the Space Fence surveillance system in 2009.
To be sure, the Space Fence system was an aging one and is overdue for an upgrade and replacement.
The Space Fence system was first brought on line in the early days of the Space Age in the 1961. Space Fence was originally known as the Naval Space Surveillance (NAVSPASUR) system until passing into the custody of the U.S. Air Force’s 20th Space Control Squadron in late 2004. Space Fence is a series of multi-static VHF receiving and transmitting sites strung out across the continental United States at latitude 33° north ranging from California to Georgia.

Space Fence is part of the greater Space Surveillance Network, and comprises about 40% of the overall observations of space debris and hardware in orbit carried out by the U.S. Air Force. Space Fence is also a unique asset in the battle to track space junk and dangerous debris, as it gives users an “uncued” tracking ability. This means that it’s constantly “on” and tracking objects that pass overhead without being specifically assigned to do so.
Space Fence also has the unique capability to track objects down to 10 centimeters in size out to a distance of 30,000 kilometres. For contrast, the average CubeSat is 10 centimetres on a side, and the tracking capability is out to about 67% of the distance to geosynchronous orbit.
Exact capabilities of the Space Fence have always been classified, but the master transmitter based at Lake Kickapoo, Texas is believed to be the most powerful continuous wave facility in the world, projecting at 768 kilowatts on a frequency of 216.97927 MHz. The original design plans may have called for a setup twice as powerful.
A replacement for Space Fence that will utilize a new and upgraded S-Band radar system is in the works, but ironically, that too is being held up pending review due to the sequestration. Right now, the Department of Defense is preparing for various scenarios that may see its budget slashed by 150 to 500 billion dollars over the next 10 years.

The U.S. Air Force has already spent $500 million to design the next generation Space Fence, and awarded contracts to Raytheon, Northrop Grumman and Lockheed Martin in 2009 for its eventual construction.
The eventual $3 billion dollar construction contract is on hold, like so many DoD programs, pending assessment by the Strategic Choices and Management Review, ordered by Secretary of Defense Chuck Hagel earlier this year.
“The AFSSS is much less capable than the space fence radar planned for Kwajalein Island in the Republic of the Marshall Islands,” stated General Shelton in a recent U.S. Air Force press release. “In fact, it’s apples and oranges in trying to compare the two systems.”
One thing’s for certain. There will be a definite capability gap when it comes to tracking space debris starting on October 1st until the next generation Space Fence comes online, which may be years in the future.
In the near term, Air Force Space Command officials have stated that a “solid space situational awareness” will be maintained by utilizing the space surveillance radar at Eglin Air Force Base in the Florida panhandle and the Perimeter Acquisition Radar Characterization System at Cavalier Air Force Station in North Dakota.
We’ve written about the mounting hazards posed by space debris before. Just earlier this year, two satellites were partially damaged due to space debris. Space junk poses a grave risk to the residents of the International Space Station, which must perform periodic Debris Avoidance Maneuvers (DAMs) to avoid collisions. Astronauts have spotted damage on solar arrays and handrails on the ISS due to micro-meteoroids and space junk. And on more than one occasion, the ISS crew has sat out a debris conjunction that was too close to call in their Soyuz spacecraft, ready to evacuate if necessary.
In 2009, a collision between Iridium 33 and the defunct Cosmos 2251 satellite spread debris across low Earth orbit. In 2007, a Chinese anti-satellite missile test also showered low Earth orbit with more of the same. Ironically, Space Fence was crucial in characterizing both events.
Satellites, such as NanoSail-D2, have demonstrated the capability to use solar sails to hasten reentry at the end of a satellites’ useful life, but we’re a long ways from seeing this capability standard on every satellite.
Amateurs will be affected by the closure of Space Fence as well. Space Weather Radio relies on ham radio operators, who listen for the “pings” generated by the Space Fence radar off of meteors, satellites and spacecraft.
“When combined with the new Joint Space Operations Center’s high-performance computing environment, the new fence will truly represent a quantum leap forward in space situational awareness for the nation,” General Shelton said.
But for now, it’s a brave and uncertain world, as Congress searches for the funds to bring this new resource online. Perhaps the old system will be rescued at the 11th hour, or perhaps the hazards of space junk will expedite the implementation of the new system. Should we pass the hat around to “Save Space Fence?”
