KENNEDY SPACE CENTER, FL – Following a flawless post midnight blastoff two mornings ago, a pair of NASA astronauts executed a flawless capture of the newest SpaceX Dragon supply ship at the International Space Station early this morning, July 20, carrying 2.5 tons of priceless research equipment and gear for the resident astronauts and cosmonauts.

As the orbiting outpost was traveling 252 statute miles over the Great Lakes, NASA’s veteran Expedition 48 Commander Jeff Williams and newly arrived NASA Flight Engineer Kate Rubins used the station’s 57.7-foot (17.6-meter) Canadian-built robotic arm to reach out and capture the Dragon CRS-9 spacecraft at 6:56 a.m. EDT.

“Good capture confirmed after a two day rendezvous,” said Houston Mission Control at NASA’s Johnson Space Center, as Dragon was approximately 30 feet (10 meters) away from the station.

“We’ve captured us a Dragon,” radioed Williams.

“Congratulations to the entire team that put this thing together, launched it, and successfully rendezvoused it to the International Space Station. We look forward to the work that it brings.”

The events unfolded live on a NASA TV webcast for all to follow along.

Furthermore, today’s dramatic Dragon arrival coincides with a renowned day in the annuls of space history. Today coincides with the 40th anniversary of humanity’s first successful touchdown on the surface of Mars by NASA’s Viking 1 lander on July 20, 1976. It paved the way for many future missions.

And Neil Armstrong and Buzz Aldrin were the first humans to land on another celestial body – the Moon – on July 20, 1969 during NASA’s Apollo 11 lunar landing mission.

Williams was working from a robotics work station in the station’s domed cupola. Rubins was Williams backup. She just arrived at the station on July 9 for a minimum 4 month stay, after launching to orbit on a Russian Soyuz on July 6 with two additional crew mates.

Ground controllers then used the robotic arm to maneuver the Dragon cargo spacecraft closer to its berthing port on the Earth facing side of the Harmony module, located at the front of the station.

Some three hours after the successful grappling, Dragon was joined to the station and bolted into place for initial berthing on the Harmony module at 10:03 a.m. EDT as the station flew about 252 statute miles over the California and Oregon border.

Controllers then activated four gangs of four bolts in the common berthing mechanism (CBM) to complete the second stage capture of the latching and berthing of Dragon to the station with a total of 16 bolts to ensure a snug connection, safety and no pressure leaks.

Crew members Williams and Rubins along with Japanese astronaut Takuya Onishi are now working to install power and data cables from the station to Dragon. They plan to open the hatch tomorrow after pressurizing the vestibule in the forward bulkhead between the station and Dragon.

Dragon reached the station after a carefully choreographed orbital chase and series of multiple thruster firings to propel the cargo ship from its preliminary post launch orbit up to the massive million pound science outpost with six resident crew members from the US, Russia and Japan.

Among the 5000 pounds of equipment on board is the first of two identical docking adapters essential for enabling station dockings next year by NASA’s new commercial astronaut taxis. This mission is all about supporting NASA’s ‘Journey to Mars’ by humans in the 2030s.

Liftoff of the SpaceX Falcon 9 rocket in its upgraded, full thrust version and the Dragon CRS-9 resupply ship took place barely 48 hours ago at 12:45 a.m. EDT Monday, July 18, from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.

Dragon reached its preliminary orbit about 10 minutes after launch and then deployed a pair of solar arrays.

SpaceX also successfully executed a spellbinding ground landing of the Falcon 9 first stage back at Cape Canaveral Air Force Station’s Landing Zone 1, located a few miles south of launch pad 40.

The dramatic ground landing of the 156 foot tall Falcon 9 first stage at LZ -1 took place about 9 minutes after liftoff. It marks only the second time a spent orbit class booster has touched down intact and upright on land.

Among the wealth of over 3900 pounds (1790 kg) of research investigations loaded on board Dragon is an off the shelf instrument designed to perform the first-ever DNA sequencing in space and the first international docking adapter (IDA) that is absolutely essential for docking of the SpaceX and Boeing built human spaceflight taxis that will ferry our astronauts to the International Space Station (ISS) in some 18 months.

Other science experiments on board include OsteoOmics to test if magnetic levitation can accurately simulate microgravity to study different types of bone cells and contribute to treatments for diseases like osteoporosis, a Phase Change Heat Exchanger to test temperature control technology in space, the Heart Cells experiments that will culture heart cells on the station to study how microgravity changes the human heart, new and more efficient three-dimensional solar cells, and new marine vessel tracking hardware known as the Automatic Identification System (AIS) that will aid in locating and identifying commercial ships across the globe.

The ring shaped IDA-2 unit is stowed in the Dragon’s unpressurized truck section. It weighs 1029 lbs (467 kg), measures about 42 inches tall and sports an inside diameter of 63 inches in diameter – so astronauts and cargo can easily float through. The outer diameter measures about 94 inches.

“Outfitted with a host of sensors and systems, the adapter is built so spacecraft systems can automatically perform all the steps of rendezvous and dock with the station without input from the astronauts. Manual backup systems will be in place on the spacecraft to allow the crew to take over steering duties, if needed,” says NASA.

“It’s a passive system which means it doesn’t take any action by the crew to allow docking to happen and I think that’s really the key,” said David Clemen Boeing’s director of Development/Modifications for the space station.

“Spacecraft flying to the station will use the sensors on the IDA to track to and help the spacecraft’s navigation system steer the spacecraft to a safe docking without astronaut involvement.”

CRS-9 counts as the company’s ninth scheduled flight to deliver supplies, science experiments and technology demonstrations to the International Space Station (ISS).

The CRS-9 mission is for the crews of Expeditions 48 and 49 to support dozens of the approximately 250 science and research investigations in progress under NASA’s Commercial Resupply Services (CRS) contract.

KENNEDY SPACE CENTER, FL – In a breathtaking feat mesmerizing hordes of thrilled spectators, SpaceX nailed today’s (July 18) back to back post midnight launch and landing of the firms Falcon 9 first stage tasked to carry a cargo Dragon loaded with over two tons of critical science, supplies and a crew docking port to the space station for NASA.

Liftoff of the SpaceX Falcon 9 rocket in its upgraded, full thrust version and the Dragon CRS-9 resupply ship took place right on time at 12:45 a.m. EDT Monday, July 18, from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.

SpaceX simultaneously successfully delivered over 5000 pounds (2200 kg) of research supplies to orbit for NASA in a commercial cargo Dragon ship, as the primary mission goal – and soft landed the approximately 60,000 pound Falcon 9 first stage on land, as the experimental secondary mission goal.

“The Falcon 9 first stage we landed is in excellent shape,” Hans Koenigsmann, SpaceX vice president of Flight Reliability, told Universe Today at the 2 a.m. EDT post launch and landing media briefing early this morning.

See my launch and landing streak shot and photos herein, including deployment of the four landing legs in the final seconds before propulsive touchdown.

The twin accomplishments will have far reaching implications for the exploration and exploitation of space for all humanity.

“Each commercial resupply flight to the space station is a significant event. Everything, from the science to the spare hardware and crew supplies, is vital for sustaining our mission,” said Kirk Shireman, NASA’s International Space Station Program manager.

“With equipment to enable novel experiments never attempted before in space, and an international docking adapter vital to the future of U.S. commercial crew spacecraft, we’re thrilled this Dragon has successfully taken flight.”

The CRS-9 mission is to support the resident six-person crew of men and women currently working on the station from the US, Russia and Japan.

The propulsive soft landing of the 156 foot tall Falcon 9 first stage of the Falcon 9 rocket on land at Cape Canaveral Air Force Station’s Landing Zone 1, located a few miles south of launch pad 40.

The dramatic ground landing at LZ -1 took place about 9 minutes after liftoff.

The first and second stages separated about two and a half minutes after liftoff and were easily visible to any eyewitness watching – backdropped by the sunshine states dark skies.

As the second stage soared to orbit, the first stage reignited a first stage engine for a series of burns targeting a return to the Cape.

We spotted the first engine firing about two mintues before landing, as it descended directly overhead of myself and everyone in the Cape Canaveral region.

For a few moments it looked like it was headed right towards us, but then steered away as planned with engines blazing to slow the boosters descent to make a gentle landing at LZ-1.

Finally the Falcon landed, obscured by a big vapor cloud and sonic booms roaring around the space coast – and waking many local residents. Several folks told me they were suddenly woken by the shocking booms reverberating inside their homes.

Some area residents even called 911 not knowing the true nature of the noises.

Dragon reached its preliminary orbit about 10 minutes after launch. Then it deployed a pair of solar arrays and began a carefully choreographed series of thruster firings to reach the space station.

If all goes well, Dragon is scheduled to arrive at the orbiting outpost on Wednesday, July 20, after a 2 day orbital chase.

NASA astronaut Jeff Williams will then reach out with the station’s 57.7-foot-long Canadian-built robotic arm to grapple and capture the private Dragon cargo ship working from a robotics work station in the station’s cupola. NASA astronaut Kate Rubins will serve as Williams backup. She just arrived at the station last week on July 9 for a minimum 4 month stay, after launching to orbit on a Russian Soyuz on July 6 with two additional crew mates.

Ground commands will be sent from Houston to the station’s arm to install Dragon on the Earth-facing bottom side of the Harmony module for its stay at the space station. The crew expects to open the hatch a day later after pressurizing the vestibule in the forward bulkhead between the station and Dragon.

Live coverage of the rendezvous and capture July 20 will begin at 5:30 a.m. on NASA TV, with installation coverage set to begin at 9:45 a.m.

CRS-9 marks only the second time SpaceX has attempted a land landing of the 15 story tall first stage booster.

The history making first time successfully took place at Landing Zone 1 (LZ 1) on Dec. 22, 2015 as part of the ORBCOMM-2 mission. Landing Zone 1 is built on the former site of Space Launch Complex 13, a U.S. Air Force rocket and missile testing range.

SpaceX also successfully recovered first stages three times in a row at sea this year on an ocean going drone ship barge using the company’s OCISLY Autonomous Spaceport Drone Ship (ASDS) on April 8, May 6 and May 27.

Altogether SpaceX has successfully landed and recovered 5 first stage booster intact and upright.

KENNEDY SPACE CENTER, FL – The outlook is outstanding for a dramatic midnight blastoff of the next SpaceX commercial cargo Dragon jam packed with some 5000 pounds of critical payloads and research supplies for NASA and heading to the space station on Monday, July 18 – that also simultaneously features an experimental land landing that promises to rock loudly across the Florida space coast and one day slash launch costs.

Dragon is carrying a crucial crew docking port absolutely essential for conducting future human space missions to the orbiting outpost as well as a host of wide ranging science experiments essential for NASA exploiting the space environment for research in low earth orbit and deep space exploration.

Liftoff of the SpaceX Falcon 9 rocket in its upgraded, full thrust version and the Dragon CRS-9 resupply ship is targeted for 12:45 a.m. EDT Monday, July 18, from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.

The CRS-9 mission is to support the resident six-person crew of men and women currently working on the station from the US, Russia and Japan.

Spectators are filling local area hotels in anticipation of a spectacular double whammy sky show comprising a thunderous nighttime launch streaking to orbit – followed minutes later by a brilliant rocket flash and night landing back at the Cape of the Falcon first stage that will send sonic booms roaring all around the coast and surrounding inland areas.

SpaceX has confirmed they are attempting the secondary mission of landing the 156 foot tall first stage of the Falcon 9 rocket on land at Cape Canaveral Air Force Station’s Landing Zone 1, located a few miles south of launch pad 40.

The weather and technical outlook for the 229 foot-tall (70 meter) Falcon 9 looks fantastic at this time, a day before liftoff.

The official weather forecast from Air Force meteorologists with the 45th Space Wing calls for a 90 percent chance of “GO” with extremely favorable conditions at launch time for liftoff of this upgraded, SpaceX Falcon 9.

The only concerns are for Cumulus clouds building up and a chance of precipitation.

And for added stargazers delight the night sky features a full moon.

The SpaceX/Dragon CRS-9 launch coverage will be broadcast on NASA TV beginning at 11:30 p.m. EDT Sunday, July 17, with additional commentary on the NASA launch blog.

SpaceX will also feature their own live webcast beginning approximately 20 minutes before launch at 12:25 a.m. EDT Monday, July 18

You can watch the launch live at NASA TV at – http://www.nasa.gov/nasatv

You can watch the launch live at SpaceX Webcast at – spacex.com/webcast

The launch window is instantaneous, meaning that any delays due to weather or technical issues will results in a minimum 2 day postponement.

If the launch does not occur Monday, a backup launch opportunity exists on 12 a.m. Wednesday, July 20, just seconds after midnight, with NASA TV coverage starting at 10:45 p.m. EDT Tuesday, July 19.

SpaceX issued a statement describing how local area residents could hear sonic booms – similar to those heard during landings of NASA’s space shuttles.

“There is the possibility that residents of northern and central Brevard County, Fla. may hear one or more sonic booms during landing. A sonic boom is a brief thunder-like noise a person on the ground hears when an aircraft or other vehicle flies overhead faster than the speed of sound,” said SpaceX.

Who could be affected?

“Residents of the communities of Cape Canaveral, Cocoa, Cocoa Beach, Courtenay, Merritt Island, Mims, Port Canaveral, Port St. John, Rockledge, Scottsmoor, Sharpes, and Titusville in Brevard County, Fla. are most likely to hear a sonic boom, although what residents experience will depend on weather conditions and other factors.”

The sights and sound are certain to be thrilling- so catch it if you can!

CRS-9 counts as the company’s ninth scheduled flight to deliver supplies, science experiments and technology demonstrations to the International Space Station (ISS).

The CRS-9 mission is for the crews of Expeditions 48 and 49 to support dozens of the approximately 250 science and research investigations in progress under NASA’s Commercial Resupply Services (CRS) contract.

SpaceX engineers conducted their standard static fire hold down test of the first stages Merlin 1D engines with the rocket erect at pad 40, this morning Saturday, July 16.

The customary test lasts a few seconds and was conducted with the Dragon bolted on top at about 9:30 a.m. I saw the test while visiting atop neighboring Launch Complex 39B at the Kennedy Space Center – see photo.

“All looks good,” reported Hans Koenigsmann, SpaceX vice president of Flight Reliability, at a media briefing this afternoon.

“We expect a GO for launch.”

Dragon will reach its preliminary orbit about 10 minutes after launch. Then it will deploy its solar arrays and begin a carefully choreographed series of thruster firings to reach the space station.
