Screenshot of Chris Hadfield showing the NASA washcloths.
The first thing I want to know is where we can get the cool, compacted NASA washcloths. But this new video from Chris Hadfield, commander of the International Space Station is pretty amazing. Hadfield has been working with schools and doing experiments suggested by students. This one was designed by students Kendra Lemke and Meredith Faulkner (10th grade) from Lockview High School in Fall River, Nova Scotia . They won a national science contest held by the Canadian Space Agency with their experiment on surface tension in space using a wet washcloth, and you can see the really nifty results here.
Below is another water-themed demonstration from Hadfield, how to wash your hands in space:
Known as Cubesats, several of these tiny but cost-effective payloads use off-the-shelf technology that you may currently carry in your pocket. In fact, engineers have put out a call for app designers to write programs for these tiny micro-satellites. Four of this new breed of satellites are part of the Antares A-One mission and another four are slated to launch tomorrow atop a Soyuz rocket from Plesetsk along with the Bion M-1 payload.
Yesterday’s launch of Orbital Sciences’ Antares rocket was scrubbed with minutes to go due to the premature retraction of an umbilical. Current plans call for a 48 hour turnaround with a new launch window opening Friday night on April 19th at 5:00 PM EDT/ 21:00 UT.
Cubesats are nothing new. As technology becomes miniaturized, so have the satellites that they’re contained in. Cubesats have even been deployed from the International Space Station.
The primary goal of the Antares A-One mission is to deploy a test mass into low Earth Orbit that simulates the Cygnus spacecraft. If all goes well, Cygnus is set to make its first flight to the ISS this summer.
But also onboard are the three unique payloads; the PhoneSat-1a, 1b & 1c cubesats and the Dove 1 cubesat.
As the name implies, the PhoneSat series of satellites are each constructed around a Nexus Smartphone and operate using Google’s very own Android operating system. The mission serves as NASA’s test bed for the concept. The phone system will monitor the orientation of the satellites. The PhoneSats will also use their off-the-shelf built-in cameras to take pictures of the Earth from orbit.
A separate watchdog circuit will reboot the phones if necessary. The PhoneSats are expected to last about a week in orbit until their batteries die. One of the PhoneSats is equipped with solar panels to test rechargeable technology for the platform.
Two of the nano satellites are built around a Samsung Nexus S and the other around a HTC Nexus Smartphone. The satellites will also use the SD card for info storage plus the 3-axis magnetometer and accelerometer incorporated into the phones for measurements and orientation.

Dove-1 will test a similar technology. It is built around a low-cost bus using off-the-shelf components. Each of the three PhoneSats cost less than $3,500 dollars U.S. to build.
Amateur radio operators will also be able to monitor the satellites as well. The PhoneSats will transmit at 437.425 MHz. Information will also available to track them in real time on the web once they’re deployed.
The two PhoneSat 1.0 satellites are dubbed Graham and Bell and will transmit every 28 and 30 seconds, and the one PhoneSat 2.0 satellite is named Alexandre and will transmit every 25 seconds.
The PhoneSat 2.0 series will also employ magnets that interact with the Earth’s magnetic field. A future application of this could include use of a PhoneSat for a possible heliophysics mission.
Although the Antares A-One mission is aiming to place the Cygnus test mass and the Cubesats in an inclination of 51.6° degrees similar to the ISS, it will not be following the ISS in its orbit and won’t present a hazard to the station.
The goal of NASA’s PhoneSat team based out of the Ames Research Center at Moffett Field California is to “release early and often.” Missions like Antares A-One present a unique opportunity for the teams to get “piggyback payloads” into orbit. To this end, NASA’s Cubesat Launch Initiative (CSLI) issues periodic calls for teams across the nation to make proposals and build tiny satellites.
Basic dimensions of a cubesat are 10x10x14 centimetres (for comparison, a CD jewel case is about 14×12 cm) and must weigh less than 1.33 kilograms for 1U, 2U & 3U variants. Up to 14kg is allowed for 6U models. Cubesats are deployed from a Poly-Picosatellite Deployer, or P-Pod.
Another set of cubesats is also slated to launch tomorrow from Plesetsk. The primary payload of the mission is deployment of the Bion M-1 biological research satellite. Bion M-1 will carry an assortment of organisms including lizards, mice and snails for a one month mission to study the effects of a long duration spaceflight on micro-organisms.
The Bion M-1 mission will also deploy the AIST microsatellite built by students of Samara Aerospace University, & BeeSats 2 & 3 provided by the Technical University of Berlin. A twin of the Dove-1 satellite launching on Antares named Dove-2 is also onboard.
One of the micro-satellites named OSSI-1 is of particular interest to backyard satellite trackers. Part of the Open Source Satellite Initiative, OSSI-1 was developed by radio amateur and artist Hojun Song. In addition to a Morse Code beacon, OSSI-1 will also contain a 44 watt optical LED beacon that will periodically be visible to observers on Earth.
Another similar project, FITSAT-1, has been tracked and imaged by observers in recent months. Follow the AmSat-UK website for predictions and visibility prospects of OSSI-1 after launch and deployment. FITSAT-1 has been visible with binoculars only, but OSSI-1 may just be visible to the unaided eye during shadow passes while it’s operational.
It will be interesting to watch these “home-brewed” projects take to orbit. The price tag and the technology is definitely within reach of a sufficiently motivated basement tinker or student team with an idea. Hey, how about the world’s first free-flying “Amateur Space Telescope?” Just throwing that out there!

In a scenario where millions of years are considered a short period of time, hours are barely a blink of an eye. While it might take ten years or more to observe a group of galaxies with a modicum of detail for telescopes around the world, the Atcama Large Millimeter/submillimeter Array (ALMA) telescope was able to do the job at amazing speed. In just a matter of hours, a team of astronomers using this super-powerful telescope homed in on the location of over a hundred star-forming galaxies in the early Universe.
Once upon a time, huge amounts of star birth occurred in early galaxies which were rich in cosmic dust. Studying these galaxies is imperative to our understanding of galactic formation and evolution – but it has proved difficult in visible light because the very dust which supports star formation also cloaks the galaxies in which they are formed. However, thanks to telescopes like ALMA, we’re able to identify and observe these galaxies by focusing on longer wavelengths. Light that comes in around one millimetre is the perfect playground for such study.
“Astronomers have waited for data like this for over a decade. ALMA is so powerful that it has revolutionised the way that we can observe these galaxies, even though the telescope was not fully completed at the time of the observations,” said Jacqueline Hodge (Max-Planck-Institut für Astronomie, Germany), lead author of the paper presenting the ALMA observations.
Just how do we know where these galaxies are located? Through the use of the ESO-operated Atacama Pathfinder Experiment telescope (APEX), astronomers were able to map these dust obscured targets to a certain degree. APEX focused its capabilities on an area of sky about the size of the full Moon in the constellation of Fornax. The study – Chandra Deep Field South – has been taken on by a variety of telescopes located both here on Earth and in space. Here is where APEX has been credited with locating 126 dusty galaxies. However, these images aren’t all they could be. Star forming areas appeared as blobs and sometimes could over-ride better images made at other wavelengths. Through the use of ALMA, these observations have been augmented, furthering the resolution in the millimetre/submillimetre portion of the spectrum and assisting astronomers in knowing precisely which galaxies are forming stars.

As all backyard astronomers know, the larger the aperture – the better the resolution. To improve their observations of the early Universe, astronomers needed a bigger telescope. APEX consists of a twelve meter diameter dish-shaped antenna, but ALMA consists of many dishes spread over long distances. The signals from all of its parts are then combined and the result is the same as if it were a giant telescope which measured the same size as the entire array. A super dish!
With the assistance of ALMA, the astronomers then took on the galaxies from the APEX map. Even though the ALMA array is still under construction and using less than a quarter of its capabilities, the team was able to complete this beginning phase of scientific observations. Speedy ALMA was up to the task. At only two minutes per galaxy, this “Super Scope” was able to resolve each one within a minuscule area two hundred times smaller than the original APEX blobs… and with 300% more sensitivity! With a track record like that, ALMA was able to double the number of observations in a matter of hours. Now the researchers were able to clearly see which galaxies contained active star forming regions and distinguish cases where multiple star-forming galaxies had melded to appear as one in earlier studies.
“We previously thought the brightest of these galaxies were forming stars a thousand times more vigorously than our own galaxy, the Milky Way, putting them at risk of blowing themselves apart. The ALMA images revealed multiple, smaller galaxies forming stars at somewhat more reasonable rates,” said Alexander Karim (Durham University, United Kingdom), a member of the team and lead author of a companion paper on this work.
Apparently ALMA is going to be a huge success. These new observations have helped to confidently document dusty star-forming galaxies from the early Universe and help to create a more detailed catalog than ever before. These new findings will assist future astronomical observations by giving researchers a reliable base on these galaxies’ properties at different wavelengths. No longer will astronomers have to “guess” at which galaxies may have melded together in images… ALMA has made it clear. However, don’t rule out the use of other venues such as APEX. The combination of both play a powerful part in observing the early Universe.
“APEX can cover a wide area of the sky faster than ALMA, and so it’s ideal for discovering these galaxies. Once we know where to look, we can use ALMA to locate them exactly,” concluded Ian Smail (Durham University, United Kingdom), co-author of the new paper.
The galaxy HFLS3 appears as a small red dot in these Herschel submillimeter images (main image, and panels on right). Subsequent observations with ground-based telescopes, ranging from optical to millimeter wavelengths (insets), revealed two galaxies appearing very close together. The two are actually at very different distances, however, and HFLS3 (blue, in millimeter wavelengths) is so far away that we are seeing it as it was when the universe was just 880 million years old.

Most of the early galaxies that astronomers have been able to observe are small with a low-to-moderate amount of star production. But now the Herschel Space Observatory has found a massive dust-filled galaxy churning out stars at an incredible rate, with all of this taking place back when the cosmos was a just 880 million years old. The galaxy is about as massive as our Milky Way, but produces stars at a rate 2,000 times greater, prompting the researchers to call it a “maximum-starburst” galaxy.
The astronomers involved in its discovery say its mere existence challenges our theories of galaxy evolution.
“Massive, intense starburst galaxies are expected to only appear at later cosmic times,” says Dominik Riechers, currently an assistant professor at Cornell. “Yet, we have discovered this colossal starburst just 880 million years after the Big Bang, when the universe was at little more than 6 percent of its current age. Riechers is the first author of the paper describing the findings in the April 18 issue of the journal Nature.
The prevailing thought on early galaxy and star formation has been that the first galaxies to form were relatively small and lightweight, containing only a few billion times the mass of our Sun. They form their first stars at rates of a few times that experienced by the Milky Way today, and the galaxies would grow by merging with other small galaxies. In theory, galaxies as massive as the newly found galaxy – named HFLS3 — should not be present so soon after the Big Bang.
HFLS3 appears as little more than a faint, red smudge in images from the Herschel Multi-tiered Extragalactic Survey (HerMES).
The extreme distance to HFLS3 means that its light has travelled for almost 13 billion years across space before reaching us. We therefore see it as it existed in the infant Universe, just 880 million years after the Big Bang or at 6.5% of the Universe’s current age.
This artist’s impression shows the “starburst” galaxy HFLS3. The galaxy appears as little more than a faint, red smudge in images from the Herschel space observatory. Image credit: ESA-C. Carreau.
Even at that young age, HFLS3 was already close to the mass of the Milky Way, with roughly 140 billion times the mass of the Sun in the form of stars and star-forming material. After another 13 billion years, it should have grown to be as big as the most massive galaxies known in the local Universe.
“Looking for the first examples of these massive star factories is like searching for a needle in a haystack; the Herschel dataset is extremely rich,” said Riechers.
Tens of thousands of massive, star-forming galaxies have been detected by Herschel as part of HerMES and sifting through them to find the most interesting ones is a challenge.
“This particular galaxy got our attention because it was bright, and yet very red compared to others like it,” said co-investigator Dave Clements of Imperial College London.
While the discovery of this single galaxy isn’t enough to overturn current theories of galaxy formation, finding more galaxies like this one could challenge those theories, the astronomers say. At the very least, theories will have to be modified to explain how this galaxy formed, Riechers says.
“This galaxy is just one spectacular example, but it’s telling us that extremely vigorous star formation was possible early in the universe,” says Jamie Bock, professor of physics at Caltech and a coauthor of the paper.

Many astronauts seem to like the Apollo 13 movie, but being technically minded folk they also enjoy pointing out what actually happened during that so-called “successful failure” that landed safely on this day in 1970.
Thomas “Ken” Mattingly was supposed to be on that crew, but was yanked at the last minute because he was exposed to the German measles. The movie shows him wallowing on the couch with a can of beer before hearing of an oxygen tank explosion on board. He then spends most of the movie stuck in a simulator, helping to save the three men on board the spacecraft.
Real life wasn’t quite the same as the movie portrayed, the real Mattingly said in a 2001 interview with NASA.
For one thing, Mattingly had no assigned role in the rescue as he was a backup crew member. He ended up working in a lot of teams rather than a single project or two. There also were some technical differences between the movie and real life. Some examples:
The “lifeboat” procedures: In the movie, mission controllers huddle in a side room and try to figure out how to stretch the resources of the lunar module — designed to carry only two men for a couple of days — into a four-day lifeboat to support three men. While this is somewhat true, NASA already had a preliminary lifeboat procedure simulated, Mattingly pointed out. The movie made it appear as though, he said, “we invented a lot of stuff”.
Somewhere in an earlier sim [simulation], there had been an occasion to do what they call LM lifeboat, which meant you had to get the crew out of the command module and into the lunar module, and they stayed there. I vaguely remember—when you have a really exciting sim, why, generally everybody knows about it. I vaguely remember that they had come up with a thing that contaminated the atmosphere in the command module, and they had to vent it, and they put the crew into the—there’s some reason that instead of staying in their suits in the command module, they put them in the lunar module while they did this.

The carbon dioxide filter: In the movie, as the crew faces a deadly buildup of carbon dioxide, a team in mission control builds a new system on the spot that adapts an originally incompatible filter. “Well, the real world is better than that,” Mattingly explained, saying there was a simulation for the Apollo 8 mission where a cabin fan was jammed due to a loose screw.
The solution that they came up with was that they could make a way to use the vacuum cleaner in the command module with some plastic bags cut up and taped to the lithium hydroxide cartridges and blow through it with a vacuum cleaner. So, having discovered it, they said, “Okay, it’s time for beer.” Well, on 13, someone says, “You remember what we did on that sim? Who did that?” So in nothing short, Joe [Joseph P.] Kerwin showed up, and we talked about “How did you build that bag and what did you do?” … Of course it worked like a gem.
Simulating the startup: In the movie, Mattingly spends hours in a simulator putting together the procedures for starting up the cold, dead command module in time to bring the astronauts safely back to Earth. While that is a good way of conveying the mission’s aim to the public, the simulation runs (done by other astronauts, Mattingly said) were more of a verification of already written procedures.
We said, “Let’s get somebody cold to go run the procedures.” So I think it was [Thomas P.] Stafford, [Joe H.] Engle — I don’t know who was the third person, might have been [Stuart A.] Roosa. But anyhow, they went to the simulator there at JSC [Johnson Space Center], and we handed them these big written procedures and said, “Here. We’re going to call these out to you, and we want you to go through, just like Jack will. We’ll read it up to you. See if there are nomenclatures that we have made confusing or whatever. Just wring it out. See if there’s anything in the process that doesn’t work.”
For more on what Mattingly thinks of the Apollo 13 movie, check out the entire transcript of his interview on NASA’s website. We’re sure there are other technical details the movie simplified or got wrong, so feel free to share your thoughts in the comments.
Lyrid meteors will appear to radiate (red circle) from a point near the bright star Vega in the constellation Lyra. This map shows the sky facing southeast around 3:30 a.m. April 22 - around the time of maximum. Stellarium
Feeling a little meteor-starved lately? Me too. It’s been a meteor shower desert since the Quadrantids of early January. That’s about to change. This weekend brings the celestial version of April showers with the annual appearance of the Lyrids.
The Lyrids ding the bell at maximum strength this weekend April 21-22 (Sunday night-Monday morning in the Americas) hurtling meteors at the modest rate of 10-20 per hour from a point in the sky not far from bright Vega in the constellation Lyra. While some showers spread their meteor crumbs over several days, the Lyrids’ peak activity lasts less than a day. The western hemisphere – particularly the western half of North America – is favored this year.

There will be a small price to pay for the show. The Lyrid radiant, the point in the sky from which the showers members radiate, rises in the east rather late – around 10:30 p.m. local time. Then there’s the bright gibbous moon, which has a habit of drowning out fainter stars and meteors alike. That makes the best time for viewing the shower after moonset or around 4 a.m. Monday morning. Since dawn begins about 5, you’ll have one good hour. That’s plenty of time to snag at least a few flaming motes of Comet Thatcher.

Like most meteor showers, the Lyrids have a parent and single parents are the rule. For the Lyrids, it’s Comet Thatcher, discovered on April 5, 1861, a week before the start of the Civil War, by amateur astronomer A.E. Thatcher observing from New York City. Later it was found to be linked to the Lyrid meteor shower.
Each year in late April, Earth passes through centuries of dust shed by the comet’s tail. When bits of Thatcher flotsam strike the air some 60-70 miles high, they burn up in flashes of meteoric light. Comet tears.

All meteors are worthy of keeping an eye on, but bear in mind that the Lyrids are no Perseids, the famed summertime shower offering up to 60 meteors per hour under dark skies. But what they lack in numbers, they make up in reliability and surprise.
Records indicate that people have been watching the Lyrids for at least 2,600 years, the longest of any shower. Our oldest descriptions come from the Chinese who penned that “stars fell like rain” on March 16, 687 BC. Apparently the shower was more active in the past and has since evolved into a minor display. But there have been occasional surprises, and that’s what keeps the Lyrids interesting.
Comet Thatcher circles the sun once every approxiimately 415 years. Each time it does, the comet leaves dust and small bits of ice and rock in a trail behind it. Sometimes it sheds more dust than others, creating denser filaments that can make for unexpectedly high numbers of Lyrid meteors when the Earth passes through. Not to scale. Illustration: Bob King
On April 20, 1803 a fire bell roused Richmond, Virginia residents from their beds to witness a similar rain of stars when up to 700 meteors per hour were seen. Other Lyrid outbursts occurred in 1922 (100 per hour), 1945 (100/hr), 1982 (90/hour). Last year’s peak hit 37 per hour from a dark sky site. Now and then, Earth encounters a thicker band of comet debris left behind by Comet Thatcher, suddenly increasing the meteor count by many times and just as suddenly dropping back to the usual 10-20 per hour.
So here’s the bottom line. Don’t expect a big blast, but do avail yourself of the leisurely pleasure of meteor watching and the possibility of seeing pieces of a comet that rounds the sun only every 415 years. Find a spot where artificial lights is at a minimum, dress warmly and head out around 3:30 a.m. Monday. Set up a comfortable lawn chair and have tea or coffee and a blanket at the ready. You’ll do well to face south or east. Now recline back to allow a fulsome view of the sky above and wait for a few well-deserved ooohs and aaahs.

What a great image! Astrophotographer Dave Walker combined seven 30-second shots of the ISS as it cuts through the sky, and it appears to slice right through the Moon! Dave used a a Canon 600D, Samyang 8mm fish-eye lens, and Vixen Polarie.
Now through the end of April provides some great sighting opportunities in the northern hemisphere for seeing the International Space Station as it flies overhead — and over your backyard! Some evenings there are even two passes. See below for another great panorama of an ISS pass, as well as information on how to find out when you can see it. It’s always an amazing sight!

UPDATE: Wednesday’s test launch for Orbital Science Corporation’s Antares rocket was aborted due to the premature disconnection of a second-stage umbilical about 12 minutes before launch was scheduled. The earliest the flight can be rescheduled is Friday, April 19.
“We are still examining all of the data, but it appears that the issue is fairly straightforward,” said Frank Culbertson, Orbital’s executive vice president and mission director for the Antares test flight, in a statement released by the company. “With this being the first launch of the new system from a new launch facility we have taken prudent steps to ensure a safe and successful outcome. Today, our scrub procedures were exercised and worked as planned. We are looking forward to a successful launch on Friday.”
[end of update]
It’s been billed as “the biggest, loudest and brightest rocket ever to launch from NASA’s Wallops Flight Facility” in Virginia, and the commercial company Orbital Sciences Corporation is ready to send their Antares rocket on its maiden test flight. Orbital is testing Antares under NASA’s Commercial Orbital Transportation Services (COTS) program, and the rocket will send a dummy module into orbit that has the same mass as Orbital’s Cygnus cargo spacecraft, as well as a few smaller satellites, testing the rocket’s capabilities.
You can watch live here via NASA TV’s Ustream. There is a press briefing at 2 pm EDT (18:00 UTC), and launch coverage starts at 4:00 pm EDT (20:00 UTC), with the launch window open between 5 and 8 pm EDT (21:00 and midnight UTC).
This will mark not only the first launch of Antares, but the first orbital launch of a liquid-fueled rocket from Wallops. If all goes well with this flight, Orbital will carry out a full flight demonstration of Antares and the Cygnus cargo delivery system to the International Space Station around mid-2013.
Dr. Sally Ride, the first American woman to fly in space
Dr. Sally K. Ride, physicist, NASA astronaut, and first American woman to fly in space, will be honored with a U.S. Navy research vessel bearing her name, which will be operated by and homeported at San Diego’s Scripps Institution of Oceanography.
“Dr. Sally Ride inspired millions of people, especially young women and girls, to reach for the stars,” said U.S. Sen. Barbara Boxer, D-Calif. “Naming the Navy’s new ocean research vessel in her honor is a fitting tribute to her legacy of innovation and discovery.”
Dr. Ride died at her home in La Jolla on July 23, 2012, after a 17-month battle with pancreatic cancer. She was 61.
Sally Ride was a NASA astronaut for 11 years before joining the UCSD faculty as a physics professor and director of the California Space Institute.
Dr. Ride was selected for NASA’s astronaut corps in 1978 and became the first American woman in space aboard Space Shuttle Challenger in 1983. In 1989, she joined the faculty of UC San Diego as professor of physics and was director of the university’s California Space Institute.
“We are touched by the extraordinary honor that this ship is being named for Sally Ride, who, after serving our nation as a pioneering and accomplished astronaut, served on the faculty of UC San Diego for nearly two decades,” said UC San Diego Chancellor Pradeep K. Khosla in a Scripps press release. “Her commitment to teaching and inspiring young minds is legendary and we take tremendous pride in this prestigious and well-deserved honor for her legacy and for UC San Diego.”
According to Gary Robbins in an article for the San Diego Union-Tribune “It is common for a research vessel to be named after an explorer or scientist. Scripps’ current fleet of Navy-owned ships includes the Roger Revelle, which bears the name of the late UC San Diego scientist who helped pioneer the study of global warming. The Woods Hole Oceanographic Institution in Cape Cod, Mass. is getting a ship named R/V Neil Armstrong.”
Rendering of the R/V Sally Ride
Designed to operate globally, R/V Sally Ride will continue the Scripps legacy of conducting pioneering ocean exploration and research critical to our understanding of our planet, our oceans, and our atmosphere. As a shared-use, general-purpose ship, R/V Sally Ride will engage in a broad spectrum of research in physics, chemistry, biology, geology, and climate science, including research missions with relevance to the Navy.
As a seagoing laboratory supporting research and education, the new ship will feature modern research instrumentation to fuel scientific exploration, including mapping systems, sensors, and profilers that will investigate features from the seafloor to the atmosphere.
“I can’t think of a more perfect name for the Navy’s new research vessel. Dr. Ride was a trailblazer in every sense of the word in the fields of science and engineering. Dr. Ride’s namesake ship and its crew will continue her legacy of courage, determination, and spirit of discovery.”
– U.S. Rep. Susan Davis, D-Calif.
R/V Sally Ride is currently under construction at Dakota Creek Industries Inc. in Anacortes, Washington, and is scheduled for launch in 2015.

The commercial space competition race is about to begin, and with a big bang at a most unexpected locale; Virginia’s Eastern shore.
The new and privately developed Antares rocket will ignite a new space race in the commercial arena – if all goes well – when the engines fire for Antares maiden soar to space slated for Wednesday, April 17.
“This is the biggest, loudest and brightest rocket ever to launch from NASA’s Wallops Flight Facility,” said former station astronaut and now Orbital Sciences manager Frank Culbertson, at a media briefing held today (April 16), 1 day prior to liftoff.
The April 17 launch is a test flight of the Antares rocket, built by Orbital Sciences Corp and is due to liftoff at 5 p.m. EDT from Mid-Atlantic Regional Spaceport (MARS) Pad-0A at NASA Wallops.
The weather forecast shows a 45% chance of favorable weather.
The mission is dubbed the A-One Test Launch Mission.
The launch will be visible along portions of the US East Coast from South Carolina to Maine, depending on viewing conditions.
Antares is the most powerful rocket ever to ascend near major American East Coast population centers, unlike anything before – and critical to keeping the ISS fully functioning.
For the past year, SpaceX Corp founded by CEO Elon Musk has monopolized all the commercial space headlines – as the first and only private company to launch a spacecraft that successfully docked at the International Space Station (ISS).

Indeed SpaceX just concluded its 3rd flight to the ISS lofting thousands of pounds (kg) of critically needed supplies to the ISS to keep it functioning – and numerous science experiments to keep the 6 person crew of astronauts busy conducting over 200 active science investigations and fulfill the stations purpose.
Orbital Sciences aims to match and perhaps even exceed the SpaceX Falcon 9 /Dragon architecture with its own ambitious space station resupply system comprising the medium class Antares rocket and Cygnus cargo resupply vehicle.
“The Cygnus can remain docked to the ISS for 30 to 90 days,” said former station astronaut and now Orbital Sciences manager Frank Culbertson at the briefing.
“Cygnus could be upgraded to stay longer perhaps up to a year in orbit,” Culbertson told Universe Today.
“Cygnus is based on the proven MPLM design. It could possibly be converted to a permanent habitation module for the ISS with added shielding and plumbing, if funding is available and if NASA wants to pursue that possibility,” Culbertson told me.
“This is a big event for this area and our country,” said Culbertson.
During the test flight Antares will boost a simulated Cygnus – known as a mass simulator – into a target orbit of 250 x 300 kilometers and inclined 51.6 degrees.
Antares rocket configuration – privately developed by Orbital Sciences Corp.
The Antares first stage is powered by dual liquid fueled AJ26 first stage rocket engines that generate a combined total thrust of some 750,000 lbs. The upper stage features a Castor 30 solid rocket motor with thrust vectoring. Antares can loft payloads weighing over 5000 kg to LEO.
Dozens of technicians were working at the pad during my photoshoot today.
The Antares/Cygnus system was developed by Orbital Sciences Corp under NASA’s Commercial Orbital Transportation Services (COTS) program to replace the ISS cargo resupply capability previously tasked to NASA’s now retired Space Shuttle fleet.
Over the next 3 to 4 years, eight Cygnus carriers will loft 20,000 kg of supplies, food, water, clothing , replacement parts and science gear to the ISS under a NASA contract valued at $1.9 Billion.
“This represents a new way of doing business for NASA,” said NASA’s commercial crew program manager Alan Lindenmoyer.
NASA Wallops Director Jay Wrobel has granted the formal Authority to Proceed for Orbital Science Corporation’s test launch of its Antares rocket.
Following today’s Flight Readiness review, Orbital managers gave a “GO” to proceed toward launch.
NASA TV launch coverage begins at 4 p.m. EDT on April 17.
Watch for my continuing on-site reports through liftoff of the Antares A-One Test flight.
