The SpaceX Dragon CRS-12 resupply ship successfully splashed down in the Pacific Ocean at approximately 10:14 a.m. EDT, 7:14 a.m. PDT, 1414 GMT Sunday, southwest of Long Beach, California, under a trio of main parachutes.
The parachute assisted splashdown marked the end of the company’s twelfth contracted cargo resupply mission to the orbiting outpost for NASA.
The capsule returned with more than 3,800 pounds (1,700 kg) of cargo and research and 20 live mice.
“Good splashdown of Dragon confirmed, completing its 12th mission to and from the @Space_Station,” SpaceX confirmed via twitter.
Liftoff of the SpaceX Falcon 9 carrying Dragon CRS-12 to orbit took place from seaside pad 39A at NASA’s Kennedy Space Center in Florida on Aug. 14 at 12:31 p.m. EDT (1631 GMT).
Dragon’s departure began early Sunday morning when Expedition 53 Flight Engineer Paolo Nespoli of ESA (European Space Agency) and ISS Commander Randy Bresnik of NASA released the Dragon spacecraft from the grips of the Canadarm2 robotic arm at 4:40 a.m. EDT, 1:40 a.m. PDT, 840 GMT.
The departure events were carried live on NASA TV. There was no live broadcast of the Pacific Ocean landing.
Working from a robotics work station inside the seven windowed domed Cupola module Nespoli and Bresnik used the station’s 57.7-foot-long (17.6 meter-long) Canadian-built robotic arm to detach Dragon from the Earth-facing port of the Harmony module and release it into space.
“We would like to give a big thanks to all the operational teams around the world that keep our presence in space possible – to the scientists and engineers that provide the outstanding research and equipment that we have in space, to NASA and all the space agencies that contribute to the space station. And to SpaceX for giving us this outstanding vehicle,” Nespoli radioed.
Dragon then backed away slowly via a trio of thruster firings.
“The three departure burns to move Dragon away from the @Space_Station are complete,” SpaceX confirmed.
The final de-orbit burn took place as planned around 9 a.m. EDT some four and a half hours after leaving the station and setting Dragon up for the scorching reentry into the Earth’s atmosphere.
“Dragon’s de-orbit burn is complete and trunk has been jettisoned. Pacific Ocean splashdown in ~30 minutes,” said SpaceX.
All the drogue and main parachutes deployed as planned during the descent to Earth.
“Dragon’s three main parachutes have been deployed.”
SpaceX commercial naval ships were on standby to retrieve the spacecraft from the ocean and sail it back to port in Long Beach, California.
Some time critical research specimens will be removed immediately for return to NASA. The remainder will be transported back with Dragon to SpaceX’s test facility in McGregor, Texas, for final post flight processing and handover to NASA.
“A variety of technological and biological studies are returning in Dragon. NASA and the Center for the Advancement of Science in Space (CASIS), the non-profit organization that manages research aboard the U.S. national laboratory portion of the space station, will receive time-sensitive samples and begin working with researchers to process and distribute them within 48 hours,” said NASA in a statement.
The Dragon resupply ship dubbed Dragon CRS-12 counts as SpaceX’s twelfth contracted commercial resupply services (CRS) mission to the International Space Station for NASA since 2012.
SpaceX holds a NASA commercial resupply services (CRS) contract that includes up to 20 missions under the original CRS-1 contract.
The 20-foot high, 12-foot-diameter Dragon CRS-12 vessel carried more than 6,400 pounds ( 2,900 kg) of science experiments and research instruments, crew supplies, food water, clothing, hardware, gear and spare parts to the million pound orbiting laboratory complex when it launched Aug. 14 from KSC pad 39A.
20 mice were also onboard and were returned alive on the round trip flight.
This mission supported dozens of the 250 research investigations and experiments being conducted by Expedition 52 and 53 crew members – including NASA’s space endurance record breaking astronaut Peggy Whitson.
Whitson returned to Earth in a Soyuz capsule earlier this month following a 10 month mission and carried out research included in the samples returned by Dragon CRS-12.
Here’s a NASA science summary:
The Lung Tissue experiment used the microgravity environment of space to test strategies for growing new lung tissue. The ultimate goal of this investigation is to produce bioengineered human lung tissue that can be used as a predictive model of human responses allowing for the study of lung development, lung physiology or disease pathology.
Samples from the CASIS PCG 7 study used the orbiting laboratory’s microgravity environment to grow larger versions of an important protein implicated in Parkinson’s disease. Developed by the Michael J. Fox Foundation, Anatrace and Com-Pac International, researchers will look to take advantage of the station’s microgravity environment which allows protein crystals to grow larger and in more perfect shapes than earth-grown crystals, allowing them to be better analyzed on Earth. Defining the exact shape and morphology of LRRK2 would help scientists to better understand the pathology of Parkinson’s and aid in the development of therapies against this target.
Mice from NASA’s Rodent Research-9 study also will return live to Earth for additional study. The investigation combined three studies into one mission, with two looking at how microgravity affects blood vessels in the brain and in the eyes and the third looking at cartilage loss in hip and knee joints. For humans on Earth, research related to limited mobility and degrading joints can help scientists understand how arthritis develops, and a better understanding of the visual impairments experienced by astronauts can help identify causes and treatments for eye disorders.
The next SpaceX Dragon is due to blastoff around December from KSC.
An Orbital ATK Cygnus cargo ship is slated to launch in November from NASA Wallops in Virginia.

KENNEDY SPACE CENTER, FL – A triad of August liftoffs from the Florida Space Coast inaugurates Monday, Aug. 14 with a science laden commercial SpaceXDragon bound for the International Space Station (ISS) – loaded with over 3 tons of NASA science, hardware and supplies including a cosmic ray detector, medical research experiments dealing with Parkinson’s disease and lung tissue, vegetable seeds, mice and much more, following a successful engine test firing of the Falcon 9 booster on Thursday.
“Static fire test of Falcon 9 complete,” SpaceX confirmed via Twitter soon after completion of the test at 9:10 a.m. EDT, Aug 10. (1310 GMT) “—targeting August 14 launch from Pad 39A for Dragon’s next resupply mission to the @Space_Station.”
Check out our photos & videos herein of the Aug. 10 static first test of the Falcon 9 first stage that paves the path to blastoff – as witnessed live by Ken Kremer and Jeff Seibert.
The triple headed sunshine state space spectacular kicks off with Monday’s lunchtime launch of the next unmanned SpaceX Dragon cargo freighter to the ISS from seaside pad 39A at NASA’s Kennedy Space Center in Florida, now targeted for Aug. 14 at 12:31 p.m. EDT (1631 GMT).
Lastly, a week after TDRS-M and just 11 days after the SpaceX Dragon an Orbital ATK Minotaur 4 rocket is due to blastoff just before midnight Aug. 25 and carry the ORS 5 mission to orbit for the U.S. military’s Operationally Responsive Space program. The Minotaur IV utilizes three stages from decommissioned Peacekeeper ICBMs formerly aimed at the Russians.
Of course getting 3 rockets off the ground from 3 different companies is all highly dependent on Florida’s hugely fickle hurricane season weather and the ever present reality of potential technical glitches, errant boaters and more – possibly resulting in a domino effect of cascading launch scrubs.
And sandwiched in between the Florida Space Coast blastoffs is the Total Solar ‘Eclipse Across America’ on Monday, Aug. 21 – for the first time in 99 years!
Although KSC and central Florida are not within the path of totality, the sun will still be about 85% obscured by the Moon.
So if you’re looking for bang for the space buck, the next two weeks have a lot to offer space and astronomy enthusiasts.
The Dragon resupply ship dubbed Dragon CRS-12 counts as SpaceX’s twelfth contracted commercial resupply services (CRS) mission to the International Space Station for NASA since 2012.
Watch this video of the Aug. 10 static hotfire test:

The 20-foot high, 12-foot-diameter Dragon CRS-12 vessel is carrying more than 6,400 pounds ( 2,900 kg) of science experiments and research instruments, crew supplies, food water, clothing, hardware, gear and spare parts to the million pound orbiting laboratory complex. 20 mice are also onboard. This will support dozens of the 250 research investigations and experiments being conducted by Expedition 52 and 53 crew members.
If you can’t personally be here to witness the launch in Florida, you can always watch NASA’s live coverage on NASA Television and the agency’s website.
The SpaceX/Dragon CRS-12 launch coverage will be broadcast on NASA TV beginning noon on Aug. 14 with additional commentary on the NASA launch blog.
SpaceX will also offer their own live webcast beginning approximately 15 minutes before launch at about 12:16 p.m. EDT.
You can watch the launch live at NASA TV at – http://www.nasa.gov/nasatv
You can also watch the launch live at SpaceX hosted Webcast at – spacex.com/webcast
In the event of delay for any reason, the next launch opportunity is Tuesday, Aug. 15 with NASA TV coverage starting about 11:30 a.m. EDT.
The weather looks decent at this time with a 70% chance of favorable conditions at launch time according to U.S. Air Force meteorologists with the 45th Space Wing Weather Squadron at Patrick Air Force Base. The primary concerns on Aug. 14 are cumulus clouds and the potential for precipitation in the flight path.
The odds remain at 70% favorable for the 24 hour scrub turnaround day on Aug. 15.
Everything is currently on track for Monday’s noontime launch of the 230 foot tall SpaceX Falcon 9 on the NASA contracted SpaceX CRS-12 resupply mission to the million pound orbiting lab complex.
However since the launch window is instantaneous there is no margin for error. In case any delays arise during the countdown due to technical or weather issues a 24 hour scrub to Tuesday will result.
The lunchtime launch coincidently offers a convenient and spectacular opportunity for fun for the whole family as space enthusiasts flock in from around the globe.
Plus SpaceX will attempt a land landing of the 156 foot tall first stage back at the Cape at Landing Zone 1 some 8 minutes after liftoff – thus a double whammy of space action !!– punctuated by multiple loud sonic booms at booster landing time that will figuratively knock your socks off.
To date SpaceX has successfully recovered 13 boosters; 5 by land and 8 by sea, over the past 18 months. It’s a feat straight out of science fiction but aimed at drastically slashing the high cost of access to space.
The recent BulgariaSat-1 and Iridium-2 missions counted as the eighth and ninth SpaceX launches of 2017.
CRS-12 marks the eleventh SpaceX launch of 2017 and will establish a new single year record.
In contrast to the prior CRS-11 mission which flew a recycled Dragon, the CRS-12 Dragon is newly built.
The CRS-12 Dragon will be the last newly built one, says NASA. The remaining SpaceX CRS mission will utilize reused spaceships.
The Falcon 9 is also new and will attempt a land landing back at the Cape at Landing Zone-1 (LZ-1).
If the Aug. 14 launch occurs as scheduled, the Dragon will reach its preliminary orbit about 10 minutes later and deploy its life giving solar arrays. Dragon then begins a 2 day orbital chase of the station via a carefully choreographed series of thruster firings that bring the commercial spacecraft to rendezvous with the space station on Aug. 16.
Dragon will be grappled with the station’s Canadian built robotic arm at approximately 7 a.m. EDT on Aug. 16 by astronauts Jack Fischer of NASA and Paolo Nespoli of ESA (European Space Agency). It then will be installed on the Harmony module.
The Dragon spacecraft will spend approximately one month attached to the space station, returning to Earth in mid-September with results of earlier experiments.
Dragon CRS-12 is SpaceX’s third contracted resupply mission to launch this year for NASA.
The prior SpaceX cargo ships launched on Feb 19 and June 3, 2017 on the CRS-10 and CRS-11 missions to the space station. CRS-10 is further noteworthy as being the first SpaceX launch of a Falcon 9 from NASA’s historic pad 39A.
SpaceX leased pad 39A from NASA in 2014 and after refurbishments placed the pad back in service this year for the first time since the retirement of the space shuttles in 2011.
Previous launches include 11 Apollo flights, the launch of the unmanned Skylab in 1973, 82 shuttle flights and five SpaceX launches.
Cargo Manifest for CRS-12:
TOTAL CARGO: 6415.4 lbs. / 2910 kg
TOTAL PRESSURIZED CARGO WITH PACKAGING: 3642 lbs. / 1652 kg
• Science Investigations 2019.4 lbs. / 916 kg
• Crew Supplies 485 lbs. / 220 kg
• Vehicle Hardware 747.4 lbs. / 339 kg
• Spacewalk Equipment 66.1 lbs. / 30 kg
• Computer Resources 116.8 lbs. / 53 kg
UNPRESSURIZED 2773.4 lbs. / 1258 kg
• Cosmic-Ray Energetics and Mass (CREAM) 2773.4 lbs. / 1258 kg
The CREAM instrument from the University of Maryland will be stowed for launch inside the Dragon’s unpressurized trunk. Astronauts will use the stations robotic arm to pluck it from the trunk and attach it to the exposed porch of the Japanese Experiment Module (JEM).
Here is a NASA description of CREAM:
The Cosmic Ray Energetics and Mass (CREAM) instrument, attached to the Japanese Experiment Module Exposed Facility, measures the charges of cosmic rays ranging from hydrogen to iron nuclei. The data collected from the CREAM instrument will be used to address fundamental science questions on the origins and history of cosmic rays. CREAM’s three-year mission will help the scientific community build a stronger understanding of the fundamental structure of the universe.
The LRRK2 experiment seeks to grow larger crystals of the protein to investigate Parkinson’s disease and help develop new therapies:
Here is a NASA description of LRRK2:
Crystallization of Leucine-rich repeat kinase 2 (LRRK2) under Microgravity Conditions (CASIS PCG 7) will use the orbiting laboratory’s microgravity environment to grow larger versions of this important protein, implicated in Parkinson’s disease. Developed by the Michael J. Fox Foundation, Anatrace and Com-Pac International, researchers will look to take advantage of the station’s microgravity environment which allows protein crystals to grow larger and in more perfect shapes than earth-grown crystals, allowing them to be better analyzed on Earth. Defining the exact shape and morphology of LRRK2 would help scientists to better understand the pathology of Parkinson’s and aid in the development of therapies against this target.
Watch this Michael J. Fox video describing the LRRK2 crystallization experiment:
