Splashdown! The SpaceX Dragon has returned home safely, splashing down in the Pacific Ocean at 16:36 UTC (12:36 p.m. EDT) on Tuesday, March 26, 2013. “Recovery ship has secured Dragon,” Tweeted SpaceX CEO Elon Musk. “Powering down all secondary systems. Cargo looks A-OK.”
A team of SpaceX engineers, technicians and divers will recover the vehicle off the coast of Baja, California, for the journey back to shore, which NASA said will take 30-48 hours.
The big job will be unloading the 3,000- plus pounds (1,360 kg) of ISS cargo and packaging inside the spacecraft. The Dragon is currently the only vehicle capable of returning cargo and important scientific experiments back to Earth.
“The scientific research delivered and being returned by Dragon enables advances in every aspect of NASA’s diverse space station science portfolio, including human research, biology and physical sciences,” said Julie Robinson, International Space Station Program
scientist. “There are more than 200 active investigations underway aboard our orbiting laboratory in space. The scientific community has
eagerly awaited the return of today’s Dragon to see what new insights the returned samples and investigations it carries will unveil.”
See more images below of Dragon’s return and mission to the ISS; we’ll be adding more as the SpaceX team supplies them!

Among the the scientific experiment returned on Dragon was the Coarsening in Solid-Liquid Mixtures (CSLM-3) experiment, which also launched to space aboard this Dragon. CLSM-3 studies how crystals known as dendrites form as a metal alloy becomes solid. The research could help engineers develop stronger materials for use in automobile, aircraft and spacecraft parts.
Dragon also is returning several human research samples that will help scientists continue to examine how the human body reacts to long-term spaceflight. The results will have implications for future space exploration and direct benefits here on Earth.
The mission was the second of at least 12 cargo resupply trips SpaceX plans to make to the space station through 2016 under NASA’s
Commercial Resupply Services contract.

The SpaceX Dragon commercially developed cargo craft loaded with thousands of pounds of precious science samples has departed from the International Space Station at 6:56 a.m EDT this morning (March 26) and is heading back to Earth today for a splashdown in the Pacific Ocean at around 12:34 p.m EDT.
The ISS crew commanded the Dragon’s release by a trigger at the robotic work station inside the Cupola as they were soaring some 250 miles over the northeast coast of Australia after Mission Control gave the “GO for release”.
A video of the unberthing is below:
Cameras aboard both the ISS and Dragon transmitted breathtaking views of the departure maneuver. The entire ISS filled the video screen as Dragon slowly pulled away.

The private Dragon was unberthed from a docking port on the Harmony node at 4:10 a.m. EDT in anticipation of today’s return to Earth.
The capsule had been docked at the orbiting outpost for three weeks since arriving on March 3.

A series of three short departure burns executed in rapid succession took Dragon safely away from the ISS and beyond the imaginary 656-foot (200-meter) “Keep Out Sphere” around the station for the journey back to Earth.
Everything with Dragon happened as expected said NASA.
“All looks beautiful and nominal as expected,” radioed the ISS crew.
The Dragon capsule is the first private ship ever to dock at the ISS.

Dragon will fire its engines for the last time for the 10 minute long deorbit burn at 11:42 a.m. EDT sending it through the Earth’s atmosphere for a fiery reentry and splashdown in the Pacific Ocean around 12:34 p.m.
“Sad to see the Dragon go,” said Marshburn. “She performed her job beautifully and is heading back to her lair. Wish her all the best for the splashdown today.”
A team of SpaceX engineers, technicians and divers will recover the vehicle after splashdown about 214 miles off the coast of Baja, California.
SpaceX recovery crews will pluck the capsule from the Pacific Ocean for the journey back to shore which will take about 30 hours.
Dragon had been scheduled to return yesterday on Monday, March 25, but was postponed due to inclement weather developing near its targeted splashdown site in the Pacific Ocean.
There was no affect on the return of the science samples and gear weighing a hefty 2668 pounds. Dragon is the only vehicle that can safely return significant amounts of science cargo and gear from the ISS following the retirement of NASA’s space shuttle orbiters.
A thruster failure shortly after liftoff nearly doomed the mission. But fast acting SpaceX engineers saved the day and restarted the engines a few hours later – read my earlier story here.

The resupply mission carried aloft some 1200 pounds of food, water and science experiments for the station crew.
After a two day flight, Marshburn captured the Dragon just 32 feet away from the station with the Canadarm2 on March 3. Ground controllers then took over Canadarm2 operations and berthed Dragon to the Harmony node.
SpaceX is under contract to NASA to deliver about 44,000 pounds of cargo to the ISS during a dozen flights over the next few years at a cost of about $1.6 Billion.
SpaceX and Orbital Sciences Corp are partnered with NASA’s Commercial Resupply Services program to replace the cargo up mass capability the US lost following the retirement of NASA’s space shuttle orbiters in 2011.
The maiden launch of Orbital’s Antares/Cygnus ISS cargo resupply program is now slated to occur on April 16-18 from NASA Wallops Flight Facility in Virginia – read my onsite photo report here.
The inaugural Antares launch will be a test flight with a simulated Cygnus.
The next SpaceX Dragon flight – dubbed CRS-3 – is slated to blast off in late November 2013.

Sunday was a big day in space, and astronaut Chris Hadfield captured the excitement in photos, and shared them via Twitter. “What a day!” Hadfield tweeted. “Reached & grabbed a Dragon, berthed her to Station & opened the hatch to find fresh fruit, notes from friends, and peanut butter.”
SpaceX’s Dragon spacecraft overcame a problem with its thrusters after reaching orbit on Friday, and on Sunday Dragon successfully approached the Station, where it was captured by Expedition 34 Commander Kevin Ford and crewmate Tom Marshburn using the station’s Canadarm2 robotic arm. Dragon was grappled at 5:31 a.m. EST, and was berthed to the Earth-facing port of the Harmony module at approximately 8:56 a.m. EST on March 3.

SpaceX’s Dragon spacecraft has arrived at the International Space Station! After overcoming a problem with its thrusters after reaching orbit on on Friday, today, Dragon successfully approached the Station, where it was captured by Expedition 34 Commander Kevin Ford and crewmate Tom Marshburn using the station’s Canadarm2 robotic arm. Dragon was grappled at 5:31 a.m. EST, and was berthed to the Earth-facing port of the Harmony module at approximately 8:56 a.m. EST on March 3.
Below, Canadian astronaut Chris Hadfield snapped a photo of Dragon as it approached the station over sub-Saharan Africa. “A surreal juxtaposition,” Hadfied said via Twitter.

Just after 10 am Eastern time, the SpaceX successfully launched their Dragon capsule on a second resupply mission to the International Space Station. The launch, rocket stage and spacecraft separations went perfectly, but the Dragon experienced an anomaly at about the time the solar arrays should have deployed. The SpaceX webcast announced that the spacecraft experienced a problem and then ended the webcast. NASA TV has not offered information either. We’ll provide more information as soon it becomes available.
Update: (10:44 EST) Elon Musk, SpaceX CEO just tweeted: “Issue with Dragon thruster pods. System inhibiting 3 of 4 from initializing. About to inhibit override.” Then minutes later he added, “Holding on solar array deployment until at least two thruster pods are active.”
See below for a continuation of our live-blogging of the Dragon anomaly, as it happened..
Also, here’s the launch video from launch to separation (note, the separation video is spectacular!):
Dragon carries 18 Draco thrusters for attitude control and maneuvering, so there may be an issue with those. Dragon’s thruster problem may be preventing the spacecraft from going into array deploy attitude, thus preventing array deploy.
Only time will tell if this is a software or hardware problem. The SpaceX press kit describes what needs to happen for solar array deploy:
Dragon separates from Falcon 9’s second stage, and seconds later, Dragon will reach its preliminary orbit. It then deploys its solar arrays and begins a carefully choreographed series of Draco thruster firings to reach the space station.
If Dragon can’t make it to the ISS, then it would need to be decided if and how it can return back to Earth on a good trajectory with limited thruster control.
The SpaceX controllers are obviously working to try and resolve the problem.
Update: 11:10 EST An update from NASA TV at about 11:10 am, said that part of response to problem with Dragon may be reorganizing the burn sequences in order for the spacecraft to be able to approach to the ISS. Musk just tweeted: “About to pass over Australia ground station and command inhibit override.”
Update: 11:25 EST: A statement from SpaceX says that “One thruster pod is running. Two are preferred to take the next step which is to deploy the solar arrays. We are working to bring up the other two in order to plan the next series of burns to get to station.”
Update: 11:42 EST: Elon Musk just tweeted: “Thruster pod 3 tank pressure trending positive. Preparing to deploy solar arrays.” That is good news.
Update: 11:50 EST: Another Tweet from Musk, with some short but sweet news: “Solar array deployment successful” That means they were abe to get at least two of the four thruster pods working, per the minimum requirement. Now, to see if the thruster problem causes any issues with getting to the ISS.
Update: 12:05 EST: Elon Musk continues to be the best source of info. He’s just tweeted, “Attempting bring up of thruster pods 2 and 4.”
We’re assuming that means 1 and 3 are already working, since it was going to take at least 2 pods thrusting to enable solar array deploy.
Update: 12:14 EST: The latest statement from SpaceX : “After Dragon achieved orbit, the spacecraft experienced an issue with a propellant valve. One thruster pod is running. We are trying to bring up the remaining three. We did go ahead and get the solar arrays deployed. Once we get at least 2 pods running, we will begin a series of burns to get to station.”
So, they were able to deploy the arrays with just one thruster pod working, and they are now working to get at least one more working. One question to consider is if the spacecraft and arrays were able to be in the right position to gather sunlight and produce power.
Update: 12:42 EST: According to reports on Twitter, a NASA official has said that three Dragon thruster pods are needed to fly to the ISS, and at this point, only one pod is working.

Update: 2:00 EST: This update from SpaceX: “SpaceX is still working through issues in Dragon’s propulsion system. The mission’s first rendezvous burn was delayed at least one orbit to about 2 p.m. EST.” (which is now)….stay tuned for updates. There will be a press conference sometime today, NASA has said, but has not yet set a specific time.
Update: 2:28 EST: NASA says the Dragon capsule Dragon will no longer be able to make its scheduled rendezvous with the station tomorrow. SpaceX indicated the rendezvous with the ISS will now not happen until at least Sunday morning. There will be a news briefing at 3pm EST.
Communication between the ISS crew and mission control confirms the delay for the rendezvous: “They are making progress recovering their prop system, but it’s not going to be in time to support the rendezvous and capture for tomorrow,” NASA’s spacecraft communicator told the crew. “So that is not going to happen tomorrow.”
“OK, copy, sounds like another off-duty day for us,” said ISS commander Kevin Ford. “We don’t wish that. We wish it gets fixed and gets up here to us. That’s really awesome they’re working their way through the problems. That’s what it’s all about.”
Update: 2:58 EST: Latest Tweet from Elon Musk has good news: “Pods 1 and 4 now online and thrusters engaged. Dragon transitioned from free drift to active control. Yes!!”
Update: 4:11 EST: Here’s a brief synopsis of the press briefing:
During the press conference, Elon Musk indicated there was a blockage in the helium line leading to the oxidizer pressurization system, or perhaps a stuck valve, and the pressure was not high enough to turn on the thrusters. The engineering team cycled the valves several times, using pressure hammering to loosen up and debris that might be stuck in the valves. And now, the pressure is nominal, with all the oxidizer tanks holding the target pressure on all 4 pods, and so Musk said he is hopeful that all the thrusters will be able to work.
Musk said they decided to deploy Dragon arrays before two thrusters were online because the temperature of the array actuators was dropping rapidly. But they also deployed solar arrays partly to mitigate Dragon’s attitude rotation “like a skater extending arms during a spin,” he said.
Musk mentioned the batteries on board had 12-14 hours of life, so deploying the arrays early was not a question of running out of power, but making sure solar arrays didn’t get so cold that they couldn’t deploy later.
NASA’s Mike Suffredini said that at least 3 of the 4 pods have to be operational in order to make an approach to the ISS.
They will make a decision on when to make the rendezvous when they’ve ascertained if the thrusters are working.
Ken Kremer will provide a more detailed update later.

The Dragon is carrying 544 kilograms (1,200 lbs) of scientific experiments and supplies to the space station, and docking was scheduled for Saturday at 6:30 a.m. ET (1100 GMT). That will likely change.
Dragon’s 18 Draco thrusters permit orbital maneuvering and attitude control. They are mounted on four pods: two of the pods contain five thrusters and the other two contain four thrusters. They are powered by nitrogen tetroxide/monomethylhydrazine, and the thrust is used to control the approach to the ISS, power departure from the ISS, and control Dragon’s attitude upon reentry.
As far as the solar arrays, each array is constructed of four panels. Each array measures 6.4 meters (21 feet). The arrays can draw up to 5,000 watts of power, which is about enough power to light about 85 light bulbs. For launch, the arrays are stowed in the unpressurized trunk of the Dragon and are covered by protective fairings. When the fairings jettison, the automated deployment of the arrays is triggered. On the way back to Earth the trunk is jettison and it, along with the arrays, burn up in the atmosphere.
If the arrays do not deploy, battery life on Dragon is only a few hours 12-14 hours, which would not be enough time to keep it alive until it would reach the ISS. It will be about 20 hours from launch until it approaches the ISS, if the mission continues on its scheduled timeline.
You may recall that during the previous mission to the ISS in October 2012 (the second flight to ISS, but first operational SpaceX resupply flight) one of the rocket’s first stage engines suffered an anomaly, where a combustion chamber ruptured. That engine was shut down, and the other engines fired longer to make up for it. The Dragon cargo made it to the correct orbit and continued on the ISS, but a satellite that was launched to orbit as a secondary payload by the Falcon 9 rocket was sent into the wrong orbit as a result of “a pre-imposed safety check required by NASA,” on October 7, and the ORBCOMM OG2 satellite later deorbited and fell back to Earth.
For this launch, all nine engines appeared to work nominally and all stages separated perfectly.
But obviously the SpaceX team saw the thruster problem immediately, as that’s when the webcast was ended.

Kennedy Space Center – All systems are GO and the weather outlook looks spectacular for the March 1 blast off of the privately developed SpaceX Falcon 9 rocket to the International Space Station (ISS).
The Falcon 9 is slated to lift off at 10:10 AM EST with a Dragon capsule loaded with fresh supplies and science gear to continued full up operation and utilization of the ISS.
Right now the weather forecast is at 80% GO on March 1 – with superbly beautiful, clear blue skies here in sunny and comfortably warm Florida from Space Launch Complex 40 at Cape Canaveral Air Force Station.
Large crowds of eager tourists, sightseers and space enthusiasts are already gathering in local hotels – most are sold out including at my hotel where I have been holding well attended ISS star parties during excellent evening viewing opportunities this week.
NASA TV will provide live launch coverage starting at 8 30 AM. SpaceX will also provide a separate feed starting about 40 minutes prior to launch.
The two stage Falcon 9 rocket was rolled out horizontally to the pad late this afternoon (Thursday, Feb. 28) in anticipation of a Friday morning launch. Myself and Dave Dickinson are on-site for Universe Today
The mission dubbed CRS-2 will be only the 2nd commercial resupply mission ever to the ISS.
There are no technical concerns at this time. Saturday March 2 is the back-up launch date in case of a last second scrub. Weather is projected as 80% favorable.
SpaceX President Gwynne Shotwell and NASA officials told me that additional launch opportunities are available Sunday, Monday and Tuesday, if needed, and later until about March 11. After that, the launch team would have to stand down to make way for the next eventual departure of a docked Soyuz and launch of a manned Russian Soyuz capsule with a new three man crew.

The SpaceX Dragon capsule is carrying about 1,200 pounds of vital supplies and research experiments for the six man international crew living aboard the million pound orbiting outpost.
SpaceX is under contract to NASA to deliver over 44,000 pounds of cargo to the ISS during a dozen flights over the next few years at a cost of about $1.6 Billion.
The capsule is fully loaded Shotwell told me. An upgraded Falcon 9 will be used in the next launch that will allow for a significant increase in the cargo up mass, Shotwell elaborated.
The Dragon is due to dock with the ISS in record time some 20 hours after blast off.

SpaceX’s Dragon spacecraft may be appearing in a backyard sky near you this weekend. Scheduled to launch this Friday on March 1st at 10:10 AM Eastern Standard Time (EST)/15:10 Universal Time (UT), this will be the 3rd resupply flight for the Dragon spacecraft to the International Space Station (ISS). And the great news is, you may just be able to catch the spacecraft as it chases down the ISS worldwide.
The Space Shuttle and the ISS captured by the author as seen from Northern Maine shortly after undocking in June, 2007.
Catching a satellite in low Earth orbit is an unforgettable sight. Satellites appear as moving “stars” against the background sky, shining steadily (unless they’re tumbling!) in the sunlight overhead in the dawn or dusk sky. Occasionally, you may catch a flare in brightness as a reflective panel catches the sunlight just right. The Hubble Space Telescope and the Iridium constellation of satellites can flare in this fashion.
At 109 metres in size, the ISS is the largest object ever constructed in orbit and is easily visible to the naked eye. It has an angular diameter of about 50” when directly overhead (about the visual size of Saturn plus rings near opposition). I can just make out a tiny box-like structure with binoculars when it passes overhead. If the orientation of the station and its solar panels is just right, it looks like a tiny luminous Star Wars TIE fighter as viewed through binoculars!

But what’s even more amazing is to watch a spacecraft rendezvous with the ISS, as diligent observers may witness this weekend. Your best bet will be to use predictions for ISS passes from your location. Heavens-Above, CALSky and Space Weather all have simple trackers for sky watchers. More advanced observers may want to use an application known as Orbitron which allows you to manually load updated Two-Line Element sets (TLEs) from Celestrak or NORAD’s Space-Track website for use in the field sans Internet connection. Note that Space-Track requires permission to access; they welcome amateur sat-spotters and educators, but they also want to assure that no “rogue entities” are accessing the site!

Wouldn’t you love to wake up to this gorgeous view of our home planet as a big hand waves a friendly good morning ?!
Well, having survived high speed wayward Asteroids and Meteors these past few days, the human crew circling Earth aboard the International Space Station (ISS) is game to snatch a flying Space Dragon before too long.
NASA will dispatch astronaut fun to orbit in the form of the privately built SpaceX Dragon in a tad less than two weeks time that the crew will ensnare with that robotic hand from Canada and join to the ISS.
On March 1 at 10:10 AM EST, a Space Exploration Technologies (SpaceX) Falcon 9 rocket is slated to blast off topped by the Dragon cargo vehicle on what will be only the 2nd commercial resupply mission ever to the ISS.
The flight, dubbed CRS-2, will lift off from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida carrying about 1,200 pounds of vital supplies and science experiments for the six man international crew living aboard the million pound orbiting outpost.

The ISS would plummet from the sky like a flaming, exploding meteor and disintegrate without periodic and critical cargo and fueling resupply flights from the ISS partner nations.
There will be some heightened anticipation for the March 1 SpaceX launch following the premature shutdown of a 1st stage Merlin engine during the last Falcon 9 launch in 2012.
The solar powered Dragon capsule will rendezvous with the ISS a day later on March 2, when NASA astronauts Kevin Ford and Tom Marshburn will reach out with the Canadian built robotic marvel, grab the Dragon by the proverbial “tail” and attach it to the Earth-facing port of the station’s Harmony module.
The Dragon will remain docked to the ISS for about three weeks while the crew unloads all manner of supplies including food, water, clothing, spare parts and gear and new science experiments.
Then the astronauts will replace all that cargo load with numerous critical experiment samples they have stored during ongoing research activities, as well as no longer needed equipment and trash totaling about 2300 pounds, for the return trip to Earth and a Pacific Ocean splashdown set for March 25 – as things stand now.

SpaceX is under contract to NASA to deliver about 44,000 pounds of cargo to the ISS during a dozen flights over the next few years at a cost of about $1.6 Billion.
SpaceX comprises one half of NASA’s Commercial Resupply Services program to replace the cargo up mass capability the US lost following the retirement of NASA’s space shuttle orbiters in 2011.
SpaceX also won a NASA contract to develop a manned version of the Dragon capsule and aims for the first crewed test flight in about 2 to 3 years – sometime during 2015 depending on the funding available from NASA.
The US is now totally dependent on the Russians to loft American astronauts to the ISS on their Soyuz capsules for at least the next 3 to 5 years directly as a result of the shuttle shutdown.
Along with SpaceX, Orbital Sciences Corp also won a $1.9 Billion cargo resupply contract from NASA to deliver some 44,000 pounds of cargo to the ISS using the firm’s new Antares rocket and Cygnus capsule – launching 8 times from a newly constructed pad at NASA’s Wallops Island Facility in Virginia.
The maiden launch of Orbital’s Antares/Cygnus system has repeatedly been delayed – like SpaceX before them.
NASA hopes the first Antares/Cygnus demonstration test flight will now occur in March or April. However, the Antares 1st stage hot fire test scheduled for earlier this week on Feb. 13 had to be aborted at the last second due to a technical glitch caused by a low nitrogen purge pressurization.
For the SpaceX launch, NASA has invited 50 lucky social media users to apply for credentials for the March 1 launch

Dragon captured by the ISS’s CanadArm2. Via NASA TV.
Running ahead of time, the International Space Station Expedition 33 crew successfully captured and installed the SpaceX Dragon capsule onto the Earth-facing port of the ISS’s Harmony module. Commander Suni Williams and astronaut Akihiko Hoshide captured the commercial spacecraft with the station’s CanadArm2 robotic arm at 6:56 a.m. EDT, and Dragon was officially berthed at 9:03 am EDT.
“Looks like we’ve tamed the Dragon,” radioed Williams. “We’re happy she’s on board with us. Thanks to everybody at SpaceX and NASA for bringing her here to us. And the ice cream.”
“This is a big moment in the course of this mission and for commercial spaceflight,” said SpaceX CEO and Chief Technical Officer Elon Musk. “We are pleased that Dragon is now ready to deliver its cargo to the International Space Station.”
The hatch will be opened tomorrow was opened earlier than expected, today at 1:40 pm EDT and Dragon will be unloaded over the next several days. Later, they will be re-packing it full of items that will be coming back to Earth, as this spacecraft has the ability to return intact, instead of burning up in the atmosphere like the other resupply ships that come to the station. Dragon will spend 18 days attached to the ISS.

Dragon is carrying nearly 400 kg (882 pounds) of supplies to the orbiting laboratory, including 117 kg (260 pounds) of crew supplies, 176 kg (390 pounds) of scientific research, 102 kg (225 pounds) of hardware and several kg/pounds of other supplies, such as food, water and Space Station parts. There are also 23 student experiments from the Student Spaceflight Experiments Program (SSEP) involving 7,420 pre-college students engaged in formal microgravity experiment design, according to SSEP director Dr. Jeff Goldstein.
The special treat that Williams mentioned is on board a new freezer called GLACIER (General Laboratory Active Cryogenic ISS Experiment Refrigerator): Blue Bell ice cream, a brand that is a favorite of astronauts training at the Johnson Space Center. The freezer will hold experiments that need to be returned to Earth for further examination.
Dragon will return a total of 758 kg (1,673 pounds), including 74 kg (163 pounds) of crew supplies, 392 kg (866 pounds) of scientific research, and 235 kg (518 pounds) of vehicle hardware and other hardware.

SpaceX has successfully launched the first official Cargo Resupply Services (CRS) mission to the International Space Station. The commercial company’s Falcon 9 rumbled rocket to life at 8:35 EDT on Oct 7 (00:35 UTC Oct. 8) in a picture perfect launch, sending the Dragon capsule on its way in the first of a dozen operational missions to deliver supplies to the orbiting laboratory. The launch took place at Launch Complex 40 at Cape Canaveral Air Force Station in Florida, just a few miles south of the space shuttle launch pads.
“This was a critical event for NASA and the nation tonight,” said NASA Administrator Charlie Bolden after the launch. “We are once again launching spacecraft from American soil with supplies that the ISS astronauts need.”
Watch the launch video below:
All the major milestones of the launch ticked off in perfect timing and execution, and the Dragon capsule is now in orbit with its solar arrays deployed. The Dragon capsule separated from the Falcon 9 about 10 minutes and 24 seconds after liftoff. Dragon should arrive at the ISS on Oct. 10 and the crew will begin berthing operations after everything checks out.
All three members of the current ISS crew were able to watch the launch live via a NASA uplink to the ISS, and Commander Suni Williams passed on her congratulations to the SpaceX team, saying “We are ready to grab Dragon!”
Williams and astronaut Akihiko Hoshide will use the CanadArm 2 to grapple the Dragon capsule around 7:22 a.m. EDT (11:22 UTC) Wednesday, moving it to a berthing at the Earth-facing port of the forward Harmony module.
Even though SpaceX sent the Dragon to the ISS in May, that was considered a demonstration flight and this flight is considered the first operational mission.
“No question, we are very excited,” said SpaceX President Gwynne Shotwell just before the launch. “Everyone was very excited in May and we are very much looking forward to moving forward with the operational missions.”
Dragon is carrying approximately 450 kg (1,000 pounds) of supplies, including food, water, scientific experiments and Space Station parts. There are also 23 student experiments from the Student Spaceflight Experiments Program (SSEP) involving 7,420 pre-college students engaged in formal microgravity experiment design, according to SSEP director Dr. Jeff Goldstein.
SpaceX and NASA revealed this weekend a special treat is on board a new freezer called GLACIER (General Laboratory Active Cryogenic ISS Experiment Refrigerator): Blue Bell ice cream, a brand that is a favorite of astronauts training at the Johnson Space Center in Houston. The freezer will be used to return frozen science experiments to Earth.
In the next three days, Dragon will perform systems checks, and start a series of Draco thruster firings to reach the International Space Station.
Dragon will return a total of 750 kg (1,673 pounds) of supplies and hardware to the ground. NASA says Dragon’s capability to return cargo from the station “is critical for supporting scientific research in the orbiting laboratory’s unique microgravity environment, which enables important benefits for humanity and vastly increases understanding of how humans can safely work, live and thrive in space for long periods. The ability to return frozen samples is a first for this flight and will be tremendously beneficial to the station’s research community. Not since the space shuttle have NASA and its international partners been able to return considerable amounts of research and samples for analysis.”
Dragon is currently scheduled to return to Earth at the end of the month, splashing down in the Pacific Ocean on October 29.
