The first International Space Station component, the Russian Zarya module, was launched 15 years ago today, on November 20, 1998. Since then, a consortium of 15 different nations have constructed a world-class orbiting laboratory, with a continual human presence onboard since 2000. Construction was considered officially complete in 2011, but new modules are still planned.
NASA is celebrating the milestone with an infographic showcasing some of the amazing and surprising facts about humanity’s home away from Earth. See below for the infographic, as well as two videos with highlights from the past 15 years of the ISS:

Tonight, Tuesday, Nov. 19, tens of millions of residents up and down the US East coast have another opportunity to watch a spectacular night launch from NASA’s Wallops Island facility in Virginia – weather permitting.
See a collection of detailed visibility and trajectory viewing maps, as well as streaming video of the launch, courtesy of rocket provider Orbital Sciences and NASA Wallops Flight Facility.
And to top that off, the four stage Minotaur 1 rocket is jam packed with a record setting payload of 29 satellites headed for Earth orbit.
And if that’s not enough to pique your interest, the Virginia seaside launch will also feature the first cubesat built by high school students.
And viewing is open to the public.
Blastoff of the Minotaur I rocket for the Department of Defense’s Operationally Responsive Space Office on the ORS-3 mission is on target for tonight, Nov. 19, from the Mid-Atlantic Regional Spaceport’s Pad-0B at NASA’s Wallops Flight Facility on the eastern shore of Virginia.
The launch window for the 70 foot tall booster opens at 7:30 pm EST and extends until 9:15 pm EST.
The ORS-3 mission is a combined US Air Force and NASA endeavor that follows the flawless Nov. 18 launch of NASA’s MAVEN Mars orbiter from Florida by just 1 day.
However the pair of East coast launch pads are separated by some 800 miles.
According to NASA and Orbital Sciences, the launch may be visible along a wide swatch from northern Florida to southern Canada and well into the Midwest stretching to Indiana – if the clouds are minimal and atmospheric conditions are favorable from your particular viewing site.
The primary payload is the Space Test Program Satellite-3 (STPSat-3), an Air Force technology-demonstration mission, according to NASA.
Also loaded aboard are thirteen small cubesats being provided through NASA’s Cubesat Launch Initiative, NASA said in a statement. Among the cubesats is NASA’s Small Satellite Program PhoneSat 2 second generation smartphone mission and the first ever cubesat assembled by high schooler’s.
Locally, the NASA Visitor Center at Wallops and the Chincoteague National Wildlife Refuge/Assateague Island National Seashore will be open for viewing the launch. Visitors to Assateague need to be on the island by 6 p.m. before the entrance gate closes.
Live coverage of the launch is available via UStream beginning at 6:30 p.m. EST on launch day. Watch below:
For the first time, astronomers are able to accurately simulate galaxies from shortly after the big bang to today by including a realistic treatment of the effects stars have on their host galaxies.
For the past few decades astronomers have simulated galaxies by mixing the basic physical ingredients — gravity, gas chemistry and the evolution of the universe — into their models.
For years their simulations have shown that gas cools off quickly and falls to the center of the galaxy. Eventually all of the gas forms stars. But observations show only “10 percent of the gas in the universe actually does so,” CalTech astronomer Dr. Philip Hopkins explained. “And in very small or very large galaxies, the number can go down to well below a percent.”
Models of galaxies create far too many stars and as a result end up weighing more than real galaxies in the observable universe. But in theory the solution is simple: the missing physics is a process known as stellar feedback.
For that, astronomers have to look at how stars help shape the evolution of the galaxies in which they reside. And what they have found is that stars affect their environments drastically.
When stars are very young they are extremely hot and blast off a high amount of radiation into space. This radiation heats up and pushes on the nearby interstellar gas. Later on stellar winds – particles streaming from the surface of stars — also push on the gas, further disrupting nearby star formation. Finally, explosions as supernovae can push the gas to nearly sonic speeds.
While astronomers have understood the missing physics for quite a while, they have not been able to successfully incorporate it a priori into their models. Despite their efforts their simulated galaxies have always weighed more than observed galaxies actually weigh.
Understanding the missing physics is a completely different question than being able to incorporate the missing physics directly into their models.
Instead, astronomers made big assumptions based on what galaxies should look like. At some point in their simulations, they had to go in by hand and tune certain parameters. They would get rid of so much gas until the results roughly matched the galaxies we observe.
“Basically, they (astronomers) said ‘we need there to be winds to explain the observations, so we’re going to insert those winds by hand into our models, and adjust the parameters until it looks like what’s observed,’ ” Hopkins told Universe Today.
At the time tuning their models in this way was the best astronomers could do and their models did help improve our understanding of galaxy evolution. But Hopkins and a team of astronomers from across North America have found a way to incorporate the missing physics — stellar feedback — directly into their models.
The research team is creating simulations that draw from stellar feedback explicitly. The FIRE (Feedback in Realistic Environments) project is a multi-year, multi-institution effort.
While it was no easy task, they incorporated the necessary and dare I say messy physics into their models, allowing for unprecedented accuracy. They tracked the affects radiation and stellar winds have on their environments and included a realistic supernovae rate.
“The result is that we see these stars pushing on the gas, and supernovae explosions sweeping up and ‘blowing out’ large amounts of material from galaxies,” Hopkins explained. “When you follow all of this, the story holds together, and indeed we can explain the observed masses of galaxies just from the input of stars.”
The results have been rewarding — providing some pretty cool videos of galaxies forming across the observable universe — and surprising.
It has become clear that the different types of stellar feedback don’t work alone. While the energy given off by stellar winds can push away interstellar gas, it cannot launch the gas out of the galaxy entirely. The necessary propulsion occurs, instead, when a supernova explosion happens nearby.
But this isn’t to say that supernova explosions play a larger role than stellar winds. If the authors left out any stellar feedback mechanism (the radiation from hot young stars, stellar winds, or supernova explosions) the results were equally poor — with too many stars and masses much too large.
“We’ve just begun to explore these new surprises, but we hope that these new tools will enable us to study a whole host of open questions in the field.”
The paper has been submitted for publication in the Monthly Notices of the Royal Astronomical Society and is available for download here.
Hopkins discusses the “Cosmological zoom-in simulation using new stellar feedback” at at workshop at the University of California, Santa Cruz earlier this year:
During that heady time when NASA was sending people to the moon, Apollo astronaut Al Shepard — so the story goes — was showing comedian Bob Hope around a NASA center. Hope went into a simulator for the lighter lunar gravity and swung a golf club around (a habit of his) as he bounced around.
“That was the inspiration, I guess,” said Michael Trostel, the curator and historian at the United States Golf Association Museum in Far Hills, New Jersey. In other words, the inspiration for Al Shepard to bring a golf club to the moon and hit a couple of balls. The golf club, in fact, is at the USGA Museum today.
Of course, it wasn’t so easy just to bring a six-iron on board — there were science experiments and other payloads for the Apollo 14 crew. According to the Smithsonian National Air and Space Museum, the golf club was actually “a contingency sample extension handle with a No. 6 iron golf club head attached.”
Unusually, as space artifacts tend to head over to the Smithsonian after missions, this particular one ended up at the USGA Museum itself. In 1972, when singer Bing Crosby (also a friend of Hope’s and Shepard’s) was a member of the board, he wrote to Shepard on behalf of the museum and asked for the club. Shepard agreed and handed it over during a special ceremony in 1974.
“The reason that it’s not in this museum was that it was personal property of Alan Shepherd. In other words, he took it to space, he brought it back, it was still his personal property he donated it and it was his. That’s the reason,” said Claire Brown, the Smithsonian National Air and Space Museum’s communications director.
“Things were a little different back then. You could take a certain amount of personal property. There are different rules now, but at the time that he did it, he was able to bring his own personal club.”
Extreme conditions surround the International Space Station’s scientific work, to say the least. It takes a rocketship to get there. Construction required more than 1,000 hours of people using spacesuits. Astronauts must balance their scientific work with the need to repair stuff when it breaks (like an ammonia coolant leak this past spring.)
But amid these conditions, despite what could have been show-stoppers to construction such as the Columbia shuttle tragedy of 2003, and in the face of changing political priorities and funding from the many nations building the station, there the ISS orbits. Fully built, although more is being added every year. The first module (Zarya) launched into space 15 years ago tomorrow. Humans have been on board continuously since November 2000, an incredible 13 years.
The bulk of construction wrapped up in 2011, but the station is still growing and changing and producing science for the researchers sending experiments up there. Below are some of the milestones of construction in the past couple of decades. Did we miss something important? Let us know in the comments.

Talk about tiny technology. The NASA PhoneSat 2.4, which is set to launch today (Nov. 19), is so small that the satellite can easy fit in just one of your hands. The agency is quite excited about this second in the series of PhoneSat launches; the first, in April, saw three “smartphone satellites” working in orbit for a week.
PhoneSat is scheduled to launch as a hitchhiker aboard a rocket that will carry the U.S. Air Force Office of Responsive Space ORS-3 mission. The payloads will lift off from the Mid Atlantic Regional Spaceport at NASA’s Wallops Flight Facility in Virginia.
“It’s tabletop technology,” stated Andrew Petro, program executive for small spacecraft technology at NASA Headquarters in Washington.
“The size of a PhoneSat makes a big difference. You don’t need a building, just a room. Everything you need to do becomes easier and more portable. The scale of things just makes everything, in many ways, easier. It really unleashes a lot of opportunity for innovation.”
PhoneSat will be at a higher altitude than its predecessors, NASA added, allowing controllers to gather information on the radiation environment to see how well vital electronics would be affected. In the long run, the agency hopes these tiny machines can be used for Earth science or communications, among other things.
“For example, work is already underway on the Edison Demonstration of Smallsat Networks (EDSN) mission,” NASA stated. “The EDSN effort consists of a loose formation of eight identical cubesats in orbit, each able to cross-link communicate with each other to perform space weather monitoring duties.”
The launch is expected at 7:30 pm EST (12:30 a.m. UTC) and you can follow it on NASA TV.
KENNEDY SPACE CENTER, FL – NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) space probe thundered to space today (Nov. 18) following a flawless blastoff from Cape Canaveral Air Force Station’s Space Launch Complex 41 at 1:28 p.m. EST atop a powerful Atlas V rocket.
“Hey Guys we’re going to Mars!” gushed Bruce Jakosky, MAVEN’s Principal Investigator at a post launch briefing for reporters.
“Now I am a Martian,” beamed Jakosky gleefully, as well as is everyone else who has worked on MAVEN since the project was conceived some ten years ago, he noted.
Today’s countdown was absolutely perfect culminating in a spectacular and on time lift off that rumbled across the Florida Space Coast to the delight of cheering crowds assembled for the historic launch aimed at discovering the history of water and habitability stretching back over billions of years on Mars.
“I take great pride in the entire team,” said Jakosky.
“Everyone was absolutely committed to making this work.”
The $671 Million MAVEN spacecraft separated from the Atlas Centaur upper stage some 52 minutes after liftoff, unfurled its wing like solar panels to produce life giving power and thus began a 10 month interplanetary voyage to the Red Planet.
“We’re currently about 14,000 miles away from Earth and heading out to the Red Planet right now,” said MAVEN Project Manager David Mitchell of NASA’s Goddard Space Flight Center at the briefing, after the 5,400-pound spacecraft had been soaring through space for barely two and a half hours.
“The first trajectory correction maneuver (TCM) is set for Dec. 3,” added Mitchell. There are a minimum of four TCM’s to ensure that the majestic probe remains precisely on course for Mars.
“Safe travels MAVEN!” said Mitchell. “We’re with you all the way.”
It will take the spacecraft 10 months to reach the Red Planet, with arrival scheduled for Sept. 22, 2014.
Jakosky noted that while the launch is a big milestone, it’s just the beginning.
MAVEN’s purpose is to accomplish world class science after arriving at Mars and completing a check-out period before it can finally begin collecting science data.
MAVEN will answer key questions about the evolution of Mars, its geology and the potential for the evolution of life.
“MAVEN is an astrobiology mission,” says Jakosky.
Mars was once wet billions of years ago, but no longer. Now it’s a cold arid world, not exactly hospitable to life.
“We want to determine what were the drivers of that change?” said Jakosky. “What is the history of Martian habitability, climate change and the potential for life?”
MAVEN will study Mars upper atmosphere to explore how the Red Planet may have lost its atmosphere over billions of years. It will measure current rates of atmospheric loss to determine how and when Mars lost its atmosphere and water.
The MAVEN probe carries nine sensors in three instrument suites.
The Particles and Fields Package, provided by the University of California at Berkeley with support from CU/LASP and NASA’s Goddard Space Flight Center in Greenbelt, Md., contains six instruments to characterize the solar wind and the ionosphere of Mars. The Remote Sensing Package, built by CU/LASP, will determine global characteristics of the upper atmosphere and ionosphere. The Neutral Gas and Ion Mass Spectrometer, built by Goddard, will measure the composition of Mars’ upper atmosphere.
“We need to know everything we can before we can send people to Mars,” said Dr. Jim Green, NASA’s Director of Planetary Science at NASA HQ in Washington, DC.
“MAVEN is a key step along the way. And the team did it under budget!” Green elaborated. “It is so exciting!”
Over the course of its one-Earth-year primary mission, MAVEN will observe all of Mars’ latitudes at altitudes ranging from 93 miles to more than 3,800 miles.
MAVEN will execute five deep dip maneuvers during the first year, descending to an altitude of 78 miles. This marks the lower boundary of the planet’s upper atmosphere.

If you can’t attend a rocket launch live, the next best thing might be watching it on a big screen, surrounded by fellow space fans. Today, as the Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft sat atop an Atlas V rocket at Cape Canaveral, space lovers from southern California collected at the Crawford Family Forum in Pasadena California to watch the launch together.
Our friends at the Planetary Society, along with Southern California Public Radio, hosted the free event, and an excited crowd of space enthusiasts of all ages attended the “launch party.”
Mat Kaplan and Bruce Betts brought the witty banter that listeners of Planetary Radio are familiar with, while Emily Lakdawalla kept the entire forum current with up-to-the-minute updates of MAVEN in her pre-launch.
Portions of Planetary Radio were recorded during the live broadcast, which gave the audience a treat, actually seeing how the radio program is created for special events such as the launch of a spacecraft.
As the timer counted down to 20 minutes before launch, Casey Dreier called in over the big-screen.
Casey, who’s the Advocacy and Outreach Coordinator of the Planetary Society, was on location at Cape Canaveral with the society’s president, Jim Bell. They both shared their experience leading up to the launch and stressed the need to continue planetary exploration in all of its forms.
Moments after Bell ended the call, Bill Nye, The Science Guy himself, called in to the Crawford Family Forum.
Replying to Kaplan’s question about excitement of ‘yet another’ Mars mission, Nye exclaimed, “What? How could there be such a thing as just another Mars mission?!” Nye continued on with a fever pitch about just how amazing it is that humans are able to have a presence on another planet, leaving any mission to Mars being nothing short of extraordinary.
As the clock ticked down and the conversation with The Science Guy ended, the official NASA video feed was brought up on the large projection screen for the excited viewers inside the forum.
Even with seconds remaining on the countdown to ignition, Emily — a seasoned Twitter user — remained dedicated to her Twitter followers while up on stage, keeping everyone in the loop about MAVEN’s upcoming explosive boost from the surface of Earth in the direction of the red planet.

At the Atlas V rocket lifts off, starting MAVEN’s journey to Mars, the room erupted in applause. Mat Kaplan commented “Always exciting. Always scary as hell,” as nearly all eyes were fixed on the video footage of the rocket soaring through the sky or their digital devices, getting new information on the rocket’s fate.
While waiting for official word on how the launch was going, the audience was treated to a live version of a Planetary Radio regular segment: Random Space Facts.
Amazingly enough, Bruce wasn’t able to find anything that happened this week in spaceflight history.
Bruce: “In this week in space history… nothing happened.” Mat: “I don’t believe that.” Bruce: “Well, this week MAVEN launched.”
The floor was opened to questions and comments from the audience, allowing children to ask their many questions about the rockets, the spacecraft and what else can be done in Universe. Jim Burke, who worked at Jet Propulsion Laboratory on the Mariner missions commented, “You’re never bored when when you watch a big rocket take off!”
While MAVEN has her scientific and communication mission ahead of her, it’s easy to conclude that her launch, just like the many that came before her, will inspire people of all ages to at least be more curious as to what’s going on in the Cosmos.
What better way to ensure a better future than to host “launch parties” like this one? The technology is available to allow people from nearly every location on the planet to gather and watch something leave it.
Coming together as a species and residents of this pale blue dot, we can send off our latest mechanical representatives into the Solar System while simultaneously inspiring the youth to embrace their curiosity, creating the future engineers and scientists that bring humanity further into the Universe.
