SpaceX has released a cool video (above) recapping the mission highlights of the historic May 22 blastoff of the firm’s Falcon 9 rocket with the Dragon spacecraft that went on to become the first privately developed vehicle in history to successfully dock to the International Space Station (ISS) on May 25, 2012.
Dragon was captured with a robotic arm operated by astronauts Don Pettit and Andre Kuipers working in tandem aboard the ISS as it approached the massive orbiting lab complex and was then berthed at an Earth facing port.
Dragon was the first US spacecraft to attach to the ISS since the retirement of NASA’s Space Shuttle program last July 2011 following the STS-135 mission of shuttle Atlantis. The 14.4 ft (4.4 meter) long resupply vehicle delivered over 1000 pounds of non-critical gear, food, clothing and science equipment to the ISS.
After spending six days at the ISS, the Dragon undocked and splashed down in the Pacific Ocean some 560 miles off the coast of California on May 31, 2012.

The Falcon 9 rocket and Dragon cargo carrier were designed, developed and built by Hawthorne, Calif., based SpaceX Corporation, founded in 2002 by CEO and Chief Designer Elon Musk.
SpaceX signed a contract with NASA in 2006 to conduct twelve Falcon 9/Dragon resupply missions to carry about 44,000 pounds of cargo to the ISS at a cost of some $1.6 Billion over the next few years. The first operational Dragon CRS mission is slated to blast off around October 2012.

On the 37th anniversary of the Apollo-Soyuz docking, a new international crew of three arrived at the International Space Station. Veteran Russian cosmonaut Yuri Malenchenko, NASA astronaut Suni Williams, and JAXA astronaut Aki Hoshide and joined their Expedition 32 crewmates early Tuesday, bringing the crew compliment on the station back to six.
At 9:40 p.m. CDT a Soyuz TMA-05M rocket lifted off from the Baikonur Cosmodrome in Kazakhstan carrying Expedition 32 Commander Yuri Malenchenko, NASA Flight Engineer Sunita “Suni” Williams and JAXA Flight Engineer Akihiko Hoshide to the International Space Station. It was a beautiful launch on a hot summer day at the Cosmodrome — watch the video after the jump:
(My favorite part was when the Soyuz punched a hole in the clouds!)
Exact time of the launch was 9:40:3.91 CDT, docking with the ISS will occur on Monday at 11:52 p.m. CDT. Read more about the crew of Expedition 32 here.
Of historical note, the Expedition 32 launch occurred on the same day that the Apollo-Soyuz Test Project launched in 1975. Designed to test the compatibility of rendezvous and docking systems and the possibility of an international space rescue, the nine-day Apollo-Soyuz mission brought together two former spaceflight rivals: the United States and the Soviet Union. Without the success of that project, we might not have had an International Space Station in orbit today.

Making its debut at the TEDxISU (International Space University) event on July 6, the video above is an inspirational call-to-arms for anyone who’s ever looked to the stars and dreamed of a day when the sky was, in fact, not the limit. From Sputnik to Space Station, from Vostok to Virgin Galactic, the video reminds us of the spirit of adventure that unites us, regardless of time or place or politics. Dreaming, after all, is universal.

After completing 193 days in space as a member of the Expedition 30 and 31 crews, astronaut Don Pettit returned to Earth on July 1, 2012. Don is not your average, ordinary, fighter-pilot astronaut: he’s got a penchant for science, with a unique way of looking at things. He spent his expedition performing crazy zero-gravity experiments, grappling the first commercial spacecraft to visit the ISS, and blogging as his alter-ego, a zuchinni plant, among other things. Universe Today had the chance to talk with Pettit this morning about his experiences:
Nancy: Good morning Don. It’s an honor to talk with you. Congratulations on such a successful expedition.
Don Pettit: It’s great to talk with you!
Nancy: You did a lot of science experiments during your stay in space, both the official ISS program experiments and also your own “Science off the Sphere” experiments. Of the official ones, which was the most interesting and engaging or perhaps what you felt was the most important experiment that you did?
Don Pettit: There were two categories of experiments that really captivated me. One is the human life science experiments that we do on ourselves, where we poke and prod ourselves and take blood and other samples, trying to figure out how this thing called the human being operates in a weightless environment. The other category of experiment that I thought was really fascinating was combustion. That’s a fancy way of saying ‘fire’ which of course is what is required to power our current civilization.

Nancy: What was your favorite Science off the Sphere experiment that you did?
Don Pettit: Oh, probably the one that has to do with the knitting needles and looking at charged droplets in a stable orbit around the knitting needles. That was really fun and simple and a fun demonstration of what you can do when you remove gravitational forces and replace them with small forces like charged forces.
Nancy: I think that was my favorite one too!
I want to say thank you on behalf of everyone, I think, on planet Earth, for the amazing images you took during your mission– the star trails, the aurorae, the transit of Venus are just a few examples — your images were just spectacular. How important is the photography that the astronauts do as far as documenting your expedition and being able to share your experiences with the public?
Don Pettit: If a picture is worth a thousand words and we take thousands of pictures that certainly says something in terms of the magnitude of communication we can have in conveying this amazing environment to people on Earth, who are of course, the ones collectively who makes this happen, and we are the lucky ones that get to go into space.
Part of any explorations, when you are going into the frontier and you come back you need to explain to people what the frontier is like, you need to share the stories and experience. Images now are one of the prime ways of doing that. I think the taking of both still images and video in space is not only an important pastime for the astronauts to do, but important to convey to the public that ultimately funds the space program, what is going on up there and how wonderful an environment this is. And eventually our technology will move to the point where people, wholesale, can jump in their rockets and go into this frontier.
Caption: Petit left his camera shutter open for long periods of time to capture star trails and trails of lights on Earth.
Nancy: We sure hope so!
You were an integral part of the SpaceX Dragon grapple and berth, the first commercial spaceship to visit the ISS. After being a part of that, what are your thoughts about the private industry becoming perhaps a vital part of human spaceflight, and in particular for space station operations?
Don Pettit: The commercial space is a natural flow for going into a frontier environment like space. You can see analogs of the wild west in the United States getting settled with a combination of both government programs and government sponsored commercial programs and I think we are going to see the same thing going into space. It’s an important aspect of opening the frontier so that more than just a few government-born programs can operate in this environment.
Nancy: Thanks Don, great to talk with you!
Don Pettit: It’s a pleasure.
I also wanted to ask him a few other questions, but ran out of time. At a reader’s suggestion I was going to ask him about the eggs on the Angry Birds Space video, and how he got them into space. Robert Pearlman from collectSPACE later asked him that question, however, and Pettit replied coyly that all astronauts has some personal items they can bring up, but as to how they got up there, Pettit said he’d leave that one unanswered.
I loved Pettit’s analogy about being an explorer of the frontier and in later interviews he had a great comment about Tweeting and exploring:
Don Pettit: Part of any exploration, like when the Antarctic was explored, they’d return home and tell their stories, spread their experience with those who didn’t have the good fortune get to go, and we are using what is available to us now. If Shackleton had the ability to Tweet, I’m sure he would have Tweeted during his expeditions to Antarctica. On station we have limited time and bandwidth and have help from people on the ground who will help get our information out.
I do get feedback (from his social media posts) and some of the comments will get condensed and sent up to me in an email message, and I take the time to read those. Some bring a pretty big smile to my face. And it is neat to see that you are having an effect, that people are following what you are doing and listening to some of the stories you have to tell.
Pettit talked more about his opportunity for photographing unique astronomical events in space:
Don Pettit: One of the most amazing things is to be able to see something like a comet. We saw a comet, saw a solar eclipse and the transit of Venus, so had a number of fairly rare natural astronomical phenomena. When you see it from space, the vantage point is slightly different and allows you to see the physics of the situation– the shadow of the Moon appears as a dark spot on Earth, and lets you know that, gosh, the guys who wrote the textbooks about this figured all this out without seeing it from this vantage point.
Pettit added that the Transit of Venus was an amazing opportunity, and he brought a full-aperture solar telescope just for the occasion. He said he hopes the images they were able to collect hopefully will be useful in the whole ensemble of images that people took from Earth of the event.
Pettit has now spent a total of 370 days in space, more than a year of his life, and he was asked if he would like to go back:
Don Pettit: I would love to fly back to station again, but there is a bunch of folks standing in line, and everyone needs to wait their turn — there is certain fairness on how this happens. I will throw my name in the hat and get back in line and see what happens. The assignments now go out to about 2015, so if space station has a lifetime to about 2020, about half of all the people going to station have already been assigned.
Later Pettit said: I would go back to space in a nano-second. That’s what I do for a living and give me a few days to get my feet on the ground and I’m ready to go again.
And then he was asked if he would go on a mission away from Earth:
Don Pettit: I’d be willing to immigrate into space and not come back as long as we would have the technology to survive. Going one way to Mars and then running out of air to die is not in the cards. If you went to Mars like people went from continental Europe to the New World, I’d load my family up in the next rocket and we’d immigrate into space.
Caption: Another star-trail image by Pettit.
Another question was if being in space ever gets routine.
Don Pettit: It can be both special and routine. Take your breakfast for example. I found that humans like to have a routine for breakfast, and that gives you certain amount of comfort. But it doesn’t get routine as far as living and working in space. Every day has another eye-opening piece of excitement and you learn something new and that is part of being on a frontier.
About his blogging from the perspective of a zucchini plant in space:
Don Pettit: I wanted to write from the equivalent of a potted plant in the corner, and I wanted to write about it because the technology associated with it is not necessarily straightforward, and I could make it like a gardening manual in space. I decided to write the story of how you grow plants in space from the eyes of a zucchini.
Pettit was asked which transition is harder: going to space or coming back to Earth:
Don Pettit: The adjustment going to space is easier than coming back down to Earth. It takes a while to get rid of this heavy feeling.
Later he said that his first thoughts on landing were, “Welcome back to gravity this is really tough,” and then “when do I get to hug my boys?”
What does the ISS smell like?
Don Pettit: Part machine shop, engine room, laboratory and then when you are cooking dinner and rip open a pouch of stew you can smell a little roast beef.

There are all sorts of details to take into consideration when traveling in deep space, such as where to go, what to do, and how to get back. Since starry-eyed dreamers often don’t take into account the practical realities of putting a human into such an environment, steely-eyed engineers are left to decide the gritty details of such a mission, such as how many pairs of socks are needed. Fortunately, NASA employs engineers who are both steely-eyed and starry-eyed, and their work has just produced an interesting report discussing the human side of deep-space exploration.
The paper, written by Michelle Rucker and Shelby Thompson of Johnson Space Center, focuses on the requirements of a ship that will take the first wave of deep-space human explorers to a near Earth asteroid (NEA), hopefully in the near future. The team stressed that they were only looking at very basic requirements and the paper only provides a basis to work from for more specialized teams that will design individual sub-systems.
To develop the basics, the team had to make some assumptions, and these assumptions are revealing for anyone interested in NASA’s future human exploration plans. The team assumed a 380 day round-trip mission to a NEA, crewed by 4 people, with just 30 days of the mission spent at the asteroid. They assumed the availability of a variety of mission-specific vehicles as well as the ability to perform extra-vehicular activities and dock with the Orion crew module, still under development at NASA. Nevertheless, such assumptions could lead to an exciting mission if they hold throughout the design process.

In addition to the assumptions, the team took advantage of knowledge gained from years of working on the International Space Station, and helped in considering details like how many packets of powdered drinks are needed for the duration of the trip as well as how much toothpaste a person uses daily in space. All of these numbers were crunched to derive overall dimensions for the craft.
Although, the sum of these volumes produced an over-sized spacecraft, the team evaluated activity frequency and duration to identify functions that could share a common volume without conflict, reducing the total volume by 24%. After adding 10% for growth, the resulting functional pressurized volume was calculated to be a minimum of 268 cu m (9,464 cu ft) distributed over the functions.
Those dimensions resulted in a 4 story structure totaling almost 280 cubic meters (10,000 cubic feet) of pressurized space that looks like it could have come right off the set of Prometheus.

The various subsystems can be broken into seven different categories. The largest is the equipment section, which takes up 22% of the spacecraft. This space would include things like the environmental control panel and navigation and communications equipment. However, the designers thought that the propulsion system, most likely a solar electric propulsion system, and all required control equipment would be part of an attachable module and would not make up part of the main living space of the habitat.
Mission Operations and Spacecraft Operations make up the next largest chunks of the habitable space, each clocking in at 20%. These areas are reserved for mission specific tasks that are not yet defined and general tasks that are necessary no matter what type of mission the habitat is launched on, such as basic maintenance and repair.
Much consideration was given to the psychological and privacy needs of the inhabitants of the ship and as such about 30% of the total habitable space is devoted to the care of the people on board, with 18% going to “individual” care and 12% going to “group” care.

Individual care includes basics such as beds, full body cleansing and toilets. Group care is more for multi-person activities, such as a dining hall, food prep and meeting areas. The last 2% of the area on board was allotted to “contingency” planning. It fits its namesake well, as the design team hopes never to have to use the space whose primary purpose is to deal with cabin depressurization, crew fatality or other unforeseeable disaster. There is also a shielded area in the interior of the habitat for refuge for the crew during a solar radiation event.
With the basics laid out, it is now up to the specialist teams to develop the next set of requirements for the sub-systems. The final design will only be completed after a long and iterative process of calculation and re-calculation, design and re-design. Assuming the teams persevere, and the space agency receives adequate funding for developing a deep space mission to an asteroid, NASA’s detail-oriented engineers will have developed a very flexible habitat module to use on the next step of human space exploration that dreamers everywhere can get excited about.

“NASA’s Dawn mission to Asteroid Vesta is going exceptionally well”, Dr. Marc Rayman, the mission’s Chief Engineer, told Universe Today in an exclusive interview as the revolutionary spacecraft nears the end of its more than 1 year long super science survey orbiting the giant space rock.
“The Dawn mission is not only going better than we had expected but even better than we had hoped.”
Dawn is Earth’s first mission ever to orbit and explore Vesta up close.
“We have acquired so much more data than we had planned even in late 2011! We have conducted a tremendous exploration of Vesta – the second most massive body between Mars and Jupiter, a giant of the main asteroid belt.”
“Now we are in our second high altitude mapping orbit (HAMO2), which is the final intensive campaign of the Vesta mission,” Rayman told me.

Indeed Dawn’s science and maneuvering endeavour’s at Vesta have proceeded so flawlessly that NASA has granted the science team a bonus of 40 days additional time in orbit split between the lower and higher science orbits known as LAMO and HAMO or the Low Altitude Mapping Orbit and the High Altitude Mapping Orbit respectively.
“Our original Vesta departure date was July 17, and now it is about August 26.” Rayman explained.
The bonus time at LAMO has already been completed. Now the team is about to begin the bonus time at HAMO – consisting of two additional mapping cycles beyond the four originally planned.
Each mapping cycle in HAMO2 consists of 10 orbits. Each orbit is about 12.5 hours.
“On July 14, we will complete mapping cycle 4 and begin 5 (of 6). On July 25 we will leave HAMO2 and escape from orbit on August 26. We will stop thrusting several times before escape to take more neat pictures, mostly of the northern hemisphere,” Rayman told me.
“As Dawn revolves, Vesta rotates on its axis beneath it, turning once every 5.3 hours.”
When Dawn arrived in orbit at Vesta in July 2011 the northern polar region was in darkness as the southern hemisphere basked in summer’s glow. Now as Dawn departs Vesta in August, virtually all of the previously unseen and unphotographed northern polar region is illuminated and will be mapped in exquisite detail.
Coincidentally on July 13/14 as HAMO2 Cycle 4 ends, I’ll be presenting a free public lecture about Dawn and NASA’s Planetary and Human Spaceflight programs at the Adirondack Public Observatory.

This view shows impact craters of various sizes and mysterious grooves parallel to the equator. The resolution of this image is about 500 meters per pixel. Credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA
Why has Dawn been granted an extended mission ?
“Dawn has gone so well that we had consumed not even one day of our 40 days of operations margin,” Rayman stated .
“That allowed us to spend more time in LAMO. We had had some unexpected events to be sure, but we managed to deal with all of them so expeditiously that the entire margin remained intact. Then we received the (entirely unrelated) 40 day extension, which allowed us to leave Vesta later. That came about because of our being able to shorten the flight from Vesta to Ceres, so we could still reach Ceres on schedule in 2015.”
“That 40 days allowed us to spend still ~ 30 more days in LAMO and increase HAMO2 by 10 days to a total of six cycles. We got still more time by finding ways to make the trip from HAMO2 to escape a little more efficiently, and that’s what allowed HAMO2 to be even longer, with the additional eight days of VIR-only observations I described in my most recent Dawn Journal.”
“The summary is that every investigation has been more productive than we could have imagined, and because the exploration of Vesta has gone so well, we have been able to apply our unused margin to get even more out of the mission. It is very very gratifying and exciting.”
So we have a few more weeks to enjoy the wondrous sights of Vesta before Dawn fires up her revolutionary ion thrusters to escape the gravitational tug of Vesta and head off to the dwarf planet Ceres, the largest asteroid in the main belt of our Solar System – and which some have speculated may hold vast caches of water and perhaps even liquid oceans suitable for sustaining life.

Sometime this summer, Austrian skydiver Felix Baumgartner will leap from the edge of space, attempting to not only break the sound barrier with his body, but also break the record for the longest freefall. As no one has successfully jumped from this height before, it’s uncertain what the highest supersonic freefall in history will look or feel like. This animated video put out by the Red Bull Stratos team provides a sense of what to expect during the attempt.
“After years of training with my team of dedicated Red Bull Stratos experts, I’ll be going on a journey that no one has ever done,” Baumgartner told Universe Today in 2010 in an email message. “If I succeed, I will be the first person to break the sound barrier, alone. That will be a record for all eternity. As such, a piece of me will become immortal. That excites me.”
42-year-old Baumgartner is hoping to jump from nearly 37 km (23 miles, 120,000 feet) to break the current jump record held by Joe Kittinger a retired Air Force officer, who jumped from 31,500 meters (31.5 km, 19.5 miles, 102,000 ft) in 1960. Now 83, Kittinger is assisting Baumgartner in preparations for the jump.
There have been several attempts to surpass Kittinger’s record, but none have succeeded, and people have given their lives for the quest. Kittinger’s jump contributed valuable data that provided ground work for spacesuit technology and knowledge about human physiology for the US space program.
Image caption: Felix Baumgartner and life support engineer Mike Todd celebrate after landing of the first manned test flight for the Red Bull Stratos in Roswell, New Mexico on March 15, 2012. Credit: Red Bull Stratos.
If Baumgartner is successful, the Red Bull Stratos mission will break four world records: the altitude record for freefall, the distance record for longest freefall, the speed record for fastest freefall by breaking the speed of sound with the human body, and the altitude record for the highest manned balloon flight.
How fast will Baumgarter need to go to beat the speed of sound? Sound travels at different speeds through the atmosphere (as well as through different mediums), depending on atmospheric density and temperature. For example, at sea level, in average conditions of about 15 degrees C (59 degrees F), sound travels at around 1,223 kph (760 mph). But at higher altitudes, where the air is colder, sound travels more slowly.
Researchers with the Red Bull Stratos mission anticipate Baumgartner could break the sound barrier at about 30,480 meters (100,000 feet) above sea level, in temperatures of -23 to -40 C (-10 to -40 F) where sound travels at about 1,110 kph (690 mph) or roughly 304 meters per second (1,000 feet per second).
So, he’ll have to go faster than those speeds – or Mach 1 — to be supersonic.
While there is no literal “barrier,” the transition to supersonic speeds can cause problems for aircraft as transonic air movement creates disruptive shock waves and turbulence. Data obtained from Chuck Yeager’s first supersonic flight in 1947 allowed for changes in design of supersonic aircraft to avoid problems. Still, some aircraft do experience problems at that point, and going supersonic has been attributed to some air disasters.
And the human body isn’t designed for supersonic speeds.
“Our biggest concern is that we don’t know how a human unencumbered by aircraft is going to transition through this,” said the project’s Medical Director Dr. Jonathan Clark, a flight surgeon for six space shuttle missions (and husband of astronaut Laurel Clark who died in the Columbia disaster in 2003), who has researched numerous aerospace disasters. “But it’s also exactly what we’re hoping to learn, for the benefit of future space flights.”
Documents provided by the Red Bull Stratos mission say that the data obtained from the mission will be shared with the scientific community, and Clark noted that he expects long-awaited medical protocols to be established as a result.
We’re not sure how we missed this when it came out last year, but this incredible video shows all 135 launches of the space shuttle program at once. Creator McLean Fahnestock calls it “The Grand Finale” and rightly so. A great display of “fireworks” and a wonderful homage to the legacy of the space shuttles.
The one launch failure, Challenger on STS-51-L does stand out in this video and the words “obviously a major malfunction” will always linger. But the drive to keep striving for the heavens will always be there.
