ISS-Above lights up when the International Space Station is going to fly over your location.
There’s a coffee shop in Pasadena, California that has a cool little device that lights up whenever the International Space Station is going to passover head, providing a little science lesson for patrons of the cafe. Called “ISS-Above,” the device is the brainchild of Liam Kennedy, a web designer, amateur astronomer and space enthusiast, and there’s a new Kickstarter for the project that will make the device available to anyone.
“It’s both an awareness thing, so more people get to know the Space Station is in their sky,” says Kennedy, “and it’s also to let those who are “up there” know that we know and appreciate what they are doing!”
That’s because not only does it light up when the ISS is nearby, it can also Tweet a message to the Space Station. Plus it has its own built-in web server to give you a ton of information about current and future passes.
It runs on a Raspberry Pi system with a memory card that can be loaded with your location information, so if you are a computer geek, this is totally up your alley! LEDs light up to alert you to the space station’s presence. There are different case options depending on how you’d like your own personal ISS-Above to look, including some colorful 3D-printed options.
But aren’t there already apps available that do this?
“True,” said Kennedy, “and I probably have almost all of them,” talking about the apps that will tell you when the ISS is going to be passing by. ”
“Those are great – BUT – that’s not what ISS-Above is about,” Kennedy said. “I wanted something small; a physical device that can just sit on a window sill or on a shelf beside the TV and light up every time the ISS is making a pass in my sky. Having these in my house for the past few months really has me understand the difference it makes to see just how frequently it passes nearby.”
For this Kickstarter, there are reward options that contain a complete ISS-Above and one of two types of colorful LED display devices, the PiGlow or the Ledborg. The PiGlow is unique with it’s circular/spiral layout while the Ledborg is intensely bright.
A complete ISS-Above device preloaded with your location is available for kicking in to the Kickstarter for $115. If you just want the memory card with your location and custom Twitter login for sending a Tweet to the ISS, then the price is just $42. There are several other options as well. The project has until February 27 to meet its funding goal of $5,000.
The device got its start when Kennedy decided to build his grandkids a device that would alert them when the ISS was going over their own backyards. He brought a sample of ISS-Above to the San Diego Mini Maker’s Faire and people went absolutely crazy for the device. (here’s their writeup about it) Then ISS-Above got noticed by Hackaday and Reddit
Why a Kickstarter? Kennedy said that while the hardware for the device can be assembled by anyone, he still has many people who have asked him to provide a complete package already setup for their location. But he can only do that if there is enough volume. “Volume means I can purchase the components with lower shipping costs and more efficiently configure and assemble complete units,” he said.
His ultimate goal is to have ISS-Above devices in all space/science museums and public observatories around the world, and for that he needs to develop public display versions of ISS-Above utilizing more extensive LED/graphics capabilities. But again, he needs support to make that possible.

We now take it for granted that astronauts on the International Space Station can tweet and post things on Facebook and G+ live from space, but it wasn’t always so. Before January of 2010, any emails, news, or Twitter messages were sent to and from the ISS in uplink and downlink packages, so for example, Twitter messages from the astronauts were downlinked to mission control in Houston, and someone there posted them on the astronauts’ Twitter accounts. But now they have “live” internet. However, as you can imagine, there are no fiberoptic cables hooking up to the ISS, so the internet speeds aren’t blazing fast. Find out how fast in this latest video update from NASA’s Space to Ground, a weekly update on what’s happening aboard the ISS.

What’s it like to be standing at a rocket launch pad? Especially when it’s a private spaceship embarking on a history making flight to the space station that’s blasting the opening salvos of the new ‘commercial space era’ heard round the world?
Thrilling beyond belief!
And what’s it like to be standing at the launch pad when the engines ignite and the bird begins soaring by guzzling hundreds of thousands of pounds of burning fuel, generating intense heat and deadly earsplitting noise?
Well for a first-hand, up-close adventure to hear the deafening sound and feel the overwhelming fury, I’ve collected a gallery of videos from the Jan. 9 blastoff of the privately built Antares rocket from NASA’s Wallops Flight Facility, VA on a historic mission to the International Space Station (ISS).
The videos were created by a team of space journalists from a variety of space websites working together to create the best possible products for everyone’s enjoyment- including Alan Walters, Mike Killian, Matt Travis, Jeff Seibert, Mike Barrett and Ken Kremer representing AmericaSpace, Zero-G News, Wired4Space and Universe Today.

Wallops is located along the eastern shore of Virginia at America’s newest space port.
And the pad sits almost directly on the Atlantic Ocean, so you can hear the waves constantly crashing on shore.
Well we always want to be as close as possible. But as you’ll see, it’s really not a very good idea to be right there.

Virtually every camera on the south side got creamed and was blown over by the approaching fiery exhaust fury seen in the videos.
Amazingly they continued taking pictures of the exhaust as they were violently hit and flung backwards.
Luckily, as they were knocked over and fell to the ground, the lenses were still facing skyward and snapping away showing the sky and exhaust plume swirling around and eventually dissipating.
Our cameras capture the experience realistically.
We’ve set them up around the north and side sides at NASA’s Wallops Launch Pad 0A on the Mid-Atlantic Regional Spaceport (MARS).

How do the cameras, called remotes, collect the imagery?
They are activated either by sound triggers or timers.
It takes a lot of hard work and equipment and doesn’t always work out as planned.
But the payoff when it does is absolutely extraordinary.

Following a two day orbital chase and an intricate series of orbit raising maneuvers, the Cygnus vessel reached the station on Sunday, Jan. 12, and was berthed by astronauts maneuvering the robot arm at an Earth-facing port on the massive orbiting lab complex.
The Orbital -1 spaceship is conducting the first of 8 operational cargo logistics flights scheduled under Orbital Sciences’ multi-year $1.9 Billion Commercial Resupply Services contract (CRS) with NASA that runs through 2016.
SpaceX likewise has a contract with NASA to deliver cargo to the ISS via their Dragon spaceship. The next SpaceX launch is slated for Feb. 22.
Stay tuned here for Ken’s continuing Orbital Sciences, SpaceX, commercial space, Chang’e-3, LADEE, Mars and more news.

We can dream, right? … because we’d all love to have a space station on the Moon. But this is as close as we’re going to get for the foreseeable future, anyway. Juan Gonzalez-Alicea of Sociedad de Astronomia del Caribe in Puerto Rico captured this great image of the International Space Station crossing in front of the crescent Moon on Dec. 6, 2013. He used a Canon 7D with a 300 mm lens, and actually got a fair amount of detail. A shot like this is tricky, as from our vantage point on Earth, it takes just a half second for the International Space Station to fly across the face of the Moon, so timing is everything!

WALLOPS ISLAND, VA – The Cygnus commercial resupply freighter is hurtling towards the International Space Station (ISS) at 17,500 MPH following the flawless Jan. 9 blastoff from NASA Wallops Island, Va., atop the Orbital Sciences Corp. Antares rocket.
Cygnus is bound for the ISS on its historic first operational mission to deliver over 1.5 tons of science experiments, provisions and belated Christmas presents to the six man crew aboard the massive orbiting outpost, under Orbital Science’s $1.9 Billion resupply contract with NASA.
See our up close photo and video gallery of the spectacular Jan 9. Launch – above and below.
The privately built Cygnus cargo vessel is in the midst of a two and a half day high speed orbital chase and is scheduled to rendezvous and dock with the station early Sunday morning, Jan 12.
The Orbital-1 ship is named the “SS C. Gordon Fullerton” in honor of NASA space shuttle astronaut C. Gordon Fullerton who later worked at Orbital Sciences and passed away in 2013.
The imagery was shot by remote cameras set up all around the NASA Wallops Launch Pad 0A as well as from the media viewing site some 2 miles away.

“All Cygnus systems are performing as expected with no issues,” said Orbital Sciences in an update.
“The spacecraft has conducted five orbit-raising maneuvers and is on track for rendezvous with the International Space Station tomorrow morning [Sunday, Jan. 12].”
“Cygnus will maneuver to a distance of about 30 feet from the station,” said Frank Culbertson, executive vice president and general manager of Orbital’s advanced spaceflight programs group, and former Space Shuttle commander.

The goal of Orbital Sciences Cygnus – and the Space X Dragon – is to restore America’s cargo delivery capabilities to low Earth orbit and the ISS that was totally lost following the forced retirement of NASA’s Space Shuttles, by utilizing new and privately developed resupply freighters that will cuts costs.
Cygnus is packed with 2,780 pounds (1261 kg) of station supplies and vital research experiments.

Expedition 38 crew members Engineers Mike Hopkins and Koichi Wakata aboard the station will reach out and with the stations 57 foot long Canadarm2 and grapple Cygnus with the robotic arm on Sunday at 6:02 a.m. EDT.
Hopkins and Wakata will then carefully maneuver the robot arm and guide Cygnus to its berthing port on the Earth-facing side of the Harmony node.
The installation begins around 7:20 a.m. EDT. And NASA TV will provide continuous live coverage of Cygnus rendezvous, docking and berthing operations.

The majestic blastoff of Orbital Science’s two stage Antares rocket took place from a beachside pad at NASA’s Wallop’s Flight Facility along the eastern shore of Virginia, Thursday, at 1:07 p.m. EST.
The station was flying about 260 miles over the Atlantic Ocean just off the coast of Brazil as Antares soared aloft.
Following the 10 minute ascent to orbit, Cygnus separated as planned from the ATK built upper stage about 30 minutes after launch. The Ukrainian supplied first stage fired for approximately four and one half minutes
The solar arrays deployed as planned once Cygnus was in Earth orbit to provide life giving energy required to command the spacecraft.
The picture perfect launch of the 133 foot tall Antares put on a spectacular sky show following a trio of delays since mid- December 2013.
The first postponement was forced when spacewalking astronauts were called on to conduct urgent repairs to fix an unexpected malfunction in the critical cooling system on board the station.
Then, unprecedented frigid weather caused by the ‘polar vortex’ forced a one day from Jan. 7 to Jan. 8.
Finally, an unexpected blast of solar radiation from the Earth’s Sun on Tuesday (Jan. 7) caused another 24 postponement because the highly energetic solar particles could have fried the delicate electronics controlling the rockets ascent with disastrous consequences.
Cygnus is loaded with science experiments, computer supplies, spacewalk tools, food, water, clothing and experimental hardware.
“The crew will unload Cygnus starting probably the next day after it docks at station,” said Culbertson.
Among the research items packed aboard the Cygnus flight are an experiment to study the effectiveness of antibiotics in space and a batch of 23 student experiments involving life sciences topics ranging from amoeba reproduction to calcium in the bones to salamanders.
The student experiments selected are from 6 middle school and high school teams from Michigan, Texas, Colorado, and Washington, DC.

Phone booths. You know, those things that Superman used to change into his cape and tights. According to news reports, the last phone booths in use in the US will be decommissioned and hauled away sometime this year. If you’ve ever had the chance to actually use one of these communication relics, you know how cramped they are inside. But they provide a good size comparison to the tiny crew quarters on board the International Space Station.
In this new video, Japanese astronaut and Expedition 38 Flight Engineer Koichi Wakata provides a tour of the crew quarters inside the International Space Station’s Harmony node where there are four individual living spaces. They include a sleeping bag, laptop computers and gear for communicating with family members.

UPDATE: The launch of Cygnus has been delayed until no earlier than January 7, 2014 due to the coolant leak at the International Space Station and necessary spacewalks to fix the problem. You can read more about the issue here and here.
WALLOPS ISLAND, VA – Orbital Sciences Corp. is marching forward with plans for a spectacular night blastoff of the firms privately developed Antares rocket and Cygnus cargo spacecraft on Thursday, Dec. 19 from a seaside pad at Wallops Island, Virginia on a mission for NASA that’s bound for the International Space Station (ISS).
The nighttime Antares liftoff is currently scheduled for prime time – at 9:19 p.m. EST from Launch Pad 0A at the Mid-Atlantic Regional Spaceport (MARS) at NASA Wallops Island, Virginia. It should be easily visible to tens of millions of residents along a wide swath of the US East Coast spanning from South Carolina to southern Maine – weather permitting.
Here’s our guide on “How to See the Antares/Cygnus Dec. 19 Night Launch” – with your own eyes – complete with viewing maps and trajectory graphics from a variety of prime viewing locations; including Philadelphia, NYC, Baltimore and historic landmarks in Washington, DC.
Update: launch postponed to mid-January 2014 to allow NASA astronauts to conduct 3 EVA’s to swap out the ammonia pump module and restore full cooling capacity to the ISS
It will be visible to spectators inland as well, stretching possibly into portions of West Virginia and western Pennsylvania.
For example; Here’s the expected view from Rocky’s famous workout on the steps of the Philadelphia Art Museum.

Up top is the map showing the maximum elevation the rocket will reach in the eastern United States. Capitol-East-Front-Steps
The flight is designated the Orbital-1, or Orb-1 mission.
Orb-1 is the first of eight commercial cargo resupply missions to the ISS by Orbital according to its Commercial Resupply Services (CRS) contract with NASA.
Of course you can still view the launch live via the NASA TV webcast.
This marks the maiden night launch of the two stage Antares rocket following a pair of daytime test and demonstration launches earlier this year, in April and September.
It’s important to note that the Dec. 19 liftoff is still dependent on NASA engineers resolving the significant issue with the ammonia cooling system that popped up late last week when a critical flow control valve malfunctioned.
If the pump valve can’t be brought back online, two American astronauts may make two or three unscheduled spacewalks starting later this week.
So in the event spacewalks are required, Antares launch could still slip a few days to the end of the launch window around Dec. 21 or Dec. 22. Thereafter the launch would be postponed until January 2014.

Here’s your chance to witness a mighty rocket launch – from the comfort of your home and nearby locations along the east coast.
And its smack dab in the middle of the Christmas and holiday season resplendent with shining bright lights.
Weather outlook appears rather promising at this time – 95% favorable chance of lift off.

Time to pull out your 3-D glasses (the red-blue kind works the best) and take a virtual spacewalk with this new video from ESA. It gives you that “Gravity”-type experience — without the spinning. But as you travel around on your jetpack, this VR video gives you a good appreciation for the size of the ISS. You also get to watch a Soyuz spacecraft undock and the docking of an Automated Transfer Vehicle.

Since the beginning of the space age, radio waves have been used for communication with spacecraft. But last month, NASA’s Lunar Laser Communication Demonstration (LLCD) made history by using a pulsed laser beam to transmit data over the 385,000 km (239,000 miles) between the Moon and Earth at a record-breaking download rate of 622 megabits per second (Mbps). This was NASA’s first system for two-way communication using a laser instead of radio waves. In our previous article today, we described how NASA will test out the Optical PAyload for Lasercomm Science (OPALS) on the International Space Station to demonstrate how videos can be beamed to Earth via laser beam.
What are the challenges in testing out an entirely new way of doing communications and other systems like navigation using lasers in space?
Don Cornwell, LLCD manager, discusses the challenges and successes they’ve had so far in this new video:
“The big change is the ability to do it by light, because the data rates that we’ve now done are just the opening shot, so to speak,” Cornwell said. “Radio communications systems have served us very well for the past 50 years but they are starting to run out of bandwidth, so in other words because of the frequency they use you can only modulate a certain portion of that frequencies and unless you move to higher frequencies – and light is a higher frequency than radio waves– you can’t squeeze a lot more bandwidth out, but the light systems in space, … we’ve now opened up a whole new field where we’re getting started , but the sky’s the limit regarding how much we can do there.”
Using lasers will allow for increased bandwidth for image resolution and 3-D video transmission from deep space, as well as allowing for tele-operation for long distances, such as from the Earth to the Moon.
LLCD is a short-duration experiment and the precursor to NASA’s long-duration demonstration, the Laser Communications Relay Demonstration (LCRD). LCRD is a part of the agency’s Technology Demonstration Missions Program, which is working to develop crosscutting technology capable of operating in the rigors of space. It is scheduled to launch in 2017.
Meanwhile, NASA has three other laser technology demonstration missions in the offing, likely launching in 2015 and 2016. One is a solar sail demonstration will enable propellantless laser in-space navigation for missions such as advanced geostorm warning, economic orbital debris removal, and deep space exploration.

Videos will beam to Earth on a laser beam in a technology demonstration coming to the International Space Station soon, says NASA’s Jet Propulsion Laboratory.
The Optical PAyload for Lasercomm Science (OPALS) plans to move videos from space to an Optical Communications Telescope Laboratory in Wrightwood, Calif. Each demonstration test will last about 100 seconds, while the station and the ground receiver can “see” each other.
While the experiment sounds awesome for sending back “home videos” from space, NASA is more touting it as a boon for transferring loads of scientific data back to Earth.
“The scientific instruments in near-Earth and deep-space missions increasingly require higher communication rates to transmit their gathered data back to Earth or to support high-data-rate applications (e.g., high-definition video streams),” stated the OPALS webpage at NASA’s Jet Propulsion Laboratory.
“Optical communications (also referred to as ‘lasercomm’) is an emerging technology wherein data is modulated onto laser beams, which offers the promise of much higher data rates than what is achievable with radio-frequency (RF) transmissions.”

The experiment page (last updated in May) says it is intended to work for about a year, with the current Expedition 37/38 and forthcoming 39/40 crews. That said, it appears the payload is not aboard station yet.
A July update from NASA said the SpaceX Dragon spacecraft is supposed to ferry OPALS to space. There hasn’t been a Dragon flight since that time, but SpaceX is listing one more for 2013 on its launch manifest.

Laser communication hit headlines earlier this fall when the NASA Lunar Atmosphere and Dust Environment Explorer (LADEE) sent a packet of information by laser from the moon, breaking records in terms of download rate (622 megabits per second).
