Videos: Dragon Capsule Now Successfully Attached to ISS

Screen capture from NASA TV of the SpaceX Dragon capsule berthed to the International Space Station.

This day will go down in history as the first time a commercial company has their own spacecraft attached to the International Space Station.

After Don Pettit grappled SpaceX’s Dragon capsule with the CanadArm2, Andre Kuipers later installed the capsule on the nadir port of the station’s Harmony node at 15:02 UTC/11:52 a.m. EDT. NASA astronaut Joe Acaba completed berthing operations by bolting the Dragon to Harmony at 16:02 UTC/12:02 p.m. EDT to the space station Friday.

Congratulations on a wonderful capture,” astronaut Megan Behnken radioed to the station crew from Mission Control. “You’ve made a lot of folks happy down here, over in Hawthorne and right here in Houston. Great job, guys.”

More videos, including the post-docking press conference with a jubilant Elon Musk and his SpaceX team.

“Today marks another critical step in the future of American spaceflight,” NASA Administrator Charles Bolden said. “Now that a U.S. company has proven its ability to resupply the space station, it opens a new frontier for commercial opportunities in space — and new job creation opportunities right here in the U.S. By handing off space station transportation to the private sector, NASA is freed up to carry out the really hard work of sending astronauts farther into the solar system than ever before.”

The plan is to wait until Saturday to open hatches. The spacecraft is carrying nearly 460 kg (1,150) pounds of equipment and supplies: 674 pounds of food and crew provisions; 46 pounds of science hardware and equipment; 271 pounds of cargo bags needed for future flights; and 22 pounds of computer equipment.

“The crew is pretty excited so don’t be surprised if they want to open the hatches a little early,” said ISS Flight Director Holly Ridings at a press conference.

The schedule has Dragon remaining berthed to the ISS until May 31. The CanadArm2 will unberth the capsule and then release it. Dragon is the only cargo ship designed to return to Earth with experiments and equipment; others ships such as the Russian Progress, the European ATV and the Japanese HTV all burn up in the atmosphere. The Russian Soyuz crew craft can bring home limited equipment.

Tally Ho Dragon!

Early today, SpaceX’s Dragon capsule successfully flew near the International Space Station and completed two big tests of its in-space capabilities, all critical tests for tomorrow’s big event: the first berthing of a commercial spacecraft to the ISS. As Dragon approached, astronaut Don Pettit spied the spacecraft first. “I think I can see it now,” he said, and Mission Control in Houston radioed back, “Copy that. Tally ho Dragon!”

With the successes today, NASA has given SpaceX a “go” for berthing activities on Friday, May 25.

Dragon initially appeared as a spot of light against the blackness of space, and later the outline of the capsule and its solar arrays became visible. It came within 2.4 km from the ISS.

Dragon communicated with the ISS and demonstrated its relative GPS, and the astronauts on the ISS successfully communicated back with Dragon by turning on its outside strobe light. The vehicle demonstrated both a pulsed and a full abort, as well as free drift, floating freely in orbit as it will when grappled by the space station’s robotic arm. And its proximity operations sensors and SpaceX’s COTS UHF Communication Unit (CUCU) all worked well during tests today.

Finally, Dragon completed a final height adjustment burn at 12:09 UTC/7:09 a.m. CDT to depart the close vicinity of the Space Station, and then began a “racetrack” trajectory to re-approach the station for grapple and berthing attempts on Friday.

“It went very close to how we had trained for it,” said ISS Flight Director Holly Ridings at a press briefing following Dragon’s maneuvers. The only glitch was a computer monitor on the space station that froze and had to be re-booted.

“Right now our mission is looking just like our simulations,” said John Couluris from SpaceX, lead mission director for the COTS 2 flight. “Today was a big confidence boost. It’s exciting being an American and putting an American spacecraft into orbit.”

Friday’s berthing will be the big test, as Dragon will do a series of burns to bring it closer to the ISS. As Dragon flies around the ISS, there are several decision points where NASA and SpaceX will check the health of the spacecraft. Each point has a “go” sequence if all is going well. When Dragon is about 10 meters away from the Station, all conditions will be assessed in order to give the final “go” for berthing. Both vehicles will be put in free drift so that no thrusters fire, and Kuipers and Pettit will use the Space Station’s Canadarm2 to grab the Dragon and berth it to the complex. Once attached, the crew will have a week to unload the supplies and then put contents in that is scheduled to return to Earth.

Dragon is the only cargo ship designed to return to Earth with experiments and equipment; others ships such as the Russian Progress, the European ATV and the Japanese HTV all burn up in the atmosphere. The Russian Soyuz crew craft can bring home limited equipment.

The initial maneuvers will start at about 06:00 UTC on May 25 (1 am CDT), with capture now scheduled for 12:00 UTC/7 am CDT, and berthing scheduled for about 15:30 UTC/10:30 am CDT. “The timing may move back or forth depending on how much time we need to evaluate the spacecraft as it sits below station in that R-bar location,” said Ridings.

Dragon is the first US-made ship to come to the ISS since about a year ago when the last space shuttle flew.

All systems are functioning nominally aboard the Earth orbiting Dragon cargo carrier launched yesterday, May 22, atop the SpaceX Falcon 9 rocket from Cape Canaveral, Florida.

SpaceX has released the picture above of the Earth as seen by a thermal imager that Dragon will use in its upcoming approach to the International Space Station.

The Falcon 9/Dragon duo thundered to space at 3:44 a.m. on May 22 from Space Launch Complex-40 at Cape Canaveral Air Force Station on a historic mission to be the first private spacecraft to dock at the International Space Station (ISS).

Docking is expected on Friday morning May 25 after an intricate series of maneuvering tests are conducted to prove that the Dragon spacecraft can safely approach and dock at the ISS.

Dragon is loaded with about 1200 pounds of supplies on a test flight aimed at showing it can partially replace the cargo carrying duties of the now retired NASA space shuttles.

A Look Inside the Dragon Capsule, Now in Orbit

SpaceX has released this automated image, a first look inside the Dragon spacecraft in orbit after the successful launch early this morning. What is all on board the Dragon? The payload includes over 300 kilograms of food, crew clothing and pantry items, a NanoRacks Module of student experiments, and a laptop computer. On board the second stage, and not on board Dragon as reported earlier, was a canister from the Celestis company that included the cremated remains of more than 300 people, including Mercury astronaut Gordon “Gordo” Cooper and the actor James Doohan, famous for playing Scotty in the “Star Trek,” series.

You can see a pdf of the entire payload here, which also includes what Dragon will be taking back home from the ISS. This capability, being able to bring experiments, used parts and other items back to Earth, can currently only be done by the Soyuz spacecraft, and so this added capability that Dragon provides is a big.

What is next for Dragon? Here’s what will be happening the next few days:

May 23: Dragon orbits Earth as it travels toward the International Space Station.

May 24: Dragon’s sensors and flight systems are subjected to a series of complicated tests to determine if the vehicle is ready to berth with the space station; these tests include maneuvers and systems checks in which the vehicle comes within 1.5 miles of the station.

May 25: NASA decides if Dragon is allowed to attempt berthing with the station. If so, Dragon approaches. It is captured by station’s robotic arm and attached to the station, a feat that requires extreme precision.

May 25 – 31: Astronauts open Dragon’s hatch, unload supplies and fill Dragon with return cargo.

May 31: After approximately two weeks, Dragon is detached from the station and returns to Earth, landing in the Pacific, hundreds of miles west of Southern California.

Today, the big events (besides launch) included the successful deploy of the solar arrays, ensuring the capsule would have power to do all the on-orbit maneuvers and berthing to the ISS.

The next big event was the opening of the Guidance, Navigation and Control (GNC) door on the spacecraft, which allows Dragon to navigate in space with its Light Detection and Ranging, or LIDAR, and a star tracker GPS system. During the press conference this morning, SpaceX CEO Elon Musk referred to this as important as “opening the payload doors, much like in the movie 2001.”

Spectacular SpaceX Launch Opens Historic New Era in Spaceflight

[/caption]Following this morning’s (May 22) spectacular nighttime blastoff of the SpaceX Falcon 9 rocket, human exploration of the cosmos embarked on a radical new course that will never be the same again.

The long awaited liftoff of the SpaceX Falcon 9 rocket at 3:44 a.m. lit up the Florida Space Coast for miles around as it roared off Pad 40 at Cape Canaveral, Florida on a history making mission bound for the International Space Station (ISS).

In a split second the page was turned to open a new era in humankinds exploration and exploitation of space that promises adventures to come that will one day be viewed as building a bridge from the dawn of the space age and the first human steps on the moon to starships that will one day ply the shores of interstellar space.

The SpaceX Falcon 9 rocket topped by the Dragon cargo capsule thundered to space from Space Launch Complex-40 at Cape Canaveral Air Force Station at 3:44 am (May 22) and is now safely in orbit with solar arrays deployed and is chasing the ISS flying some 249 miles overhead.

“I congratulate SpaceX for just an absolutely amazing countdown, launch and orbit insertion today, said Bill Gerstenmaier, Associate Administrator for Human Exploration and Operations Mission Directorate at NASA headquarters in Washington. “I’ve had the pleasure of working down here at the Cape with a lot of fantastic teams that have put together a lot of quality rockets and launched a lot of amazing things. I tell you, the SpaceX team, there is none better than this team that has really done a phenomenal job today.”

The on time Falcon 9 blastoff came three days after the first launch attempt was aborted a T Minus 0 when a computer automatically shutdown the already firing engines as it detected a high chamber pressure in one of the nine first stage Merlin 1 C engines.

“Every bit of adrenaline in my body released at that moment,” said Elon Musk to reporters at the post launch media briefing about the moment the rocket lifted off the pad. Musk is the founder, CEO and chief designer of SpaceX. “People were really giving it their all. For us, it was like winning the Super Bowl.”

Dragon will be the first private spacecraft that will rendezvous and dock with the ISS. After conducting a complicated series of rendezvous tests and maneuvers, docking is expected on day 4 of the mission on Friday morning EDT, May 26.

“There’s still a thousand things that have to go right, but we are looking forward to this exciting mission,” said Alan Lindenmoyer, manager of NASA’s Commercial Crew and Cargo Program.

Dragon will fly within range of the robotic arm. NASA Astronaut Don Pettit will grapple it and berth the Dragon on the earth facing side of the Harmony module.

Do you believe in Dragons? In a spectacular night launch, SpaceX’s Falcon 9 rocket carrying the Dragon capsule is now heading for the first commercial rendezvous at the International Space Station. With an official launch time of 07:44:38 UTC/3:44:38 a.m. EDT, the Dragon capsule is now safely in orbit with its solar array wings deployed, and the mission begins for the COTS-2/3 cargo delivery demonstration mission.

“Falcon flew perfectly!! Dragon in orbit, comm locked and solar arrays active!! Feels like a giant weight just came off my back :),” Tweeted Elon Musk, SpaceX CEO.

“Today marks the beginning of a new era in exploration,” said NASA Administrator Charles Bolden, following the launch. “A private company has launched a spacecraft to the International Space Station that will attempt to dock there for the first time. And while there is a lot of work ahead to successfully complete this mission, we are certainly off to good start… This demonstrates the future of American space exploration, to have private industry provide for access to low Earth orbit while NASA goes off and does what it does best in exploring beyond in our solar system. It’s a great day for America, a great day for the world because there were people who thought that we were going away. We are not going away at all. The SpaceX/NASA team came through with flying colors.”

[/caption]
“The entire team at SpaceX and at NASA should be commended for their success on this third test flight of the Falcon 9 rocket,” said former astronaut Michael Lopez-Alegria, who is now the President of the Commercial Spaceflight Federation. “The preparations and precautions taken by SpaceX and NASA in months past have contributed to their exemplary performance today. After seeing the smooth launch SpaceX just executed, it is easy to forget that this is indeed rocket science.”

The Falcon 9 appeared to fly flawlessly, and after the crucial moment of solar array deploy, there were hugs and cheers all around in SpaceX’s mission control room.

The rendezvous at the ISS will happen on May 25, with the Canadarm2 grapple occurring at 12:06 GMT (8:06 a.m. EDT) on the 25th.

NASA has updated their Satellite Sightings page to include when the Dragon will be visible in the night skies.

The White House issued a statement from John Holdren, Assistant to the President for Science and Technology: “Congratulations to the teams at SpaceX and NASA for this morning’s successful launch of the Falcon 9 rocket from Cape Canaveral Air Force Station in Florida. Every launch into space is a thrilling event, but this one is especially exciting because it represents the potential of a new era in American spaceflight. Partnering with U.S. companies such as SpaceX to provide cargo and eventually crew service to the International Space Station is a cornerstone of the President’s plan for maintaining America’s leadership in space. This expanded role for the private sector will free up more of NASA’s resources to do what NASA does best — tackle the most demanding technological challenges in space, including those of human space flight beyond low Earth orbit. I could not be more proud of our NASA and SpaceX scientists and engineers, and I look forward to following this and many more missions like it.”

We’ll have more details and images from Ken Kremer and our group of photographers, live from Kennedy Space Center.

T-0 Launch Abort for Dragon

Screenshot from NASA TV of the Falcon 9 rocket after a final-second launch abort.

[/caption]

SpaceX’s attempt to launch their Falcon 9 rocket with the Dragon spacecraft was aborted by the computer at T-0 due to a high pressure reading on engine 5 of the first stage. The rocket’s nine main engines were ignited, but were automaticalaly shut down before liftoff. The vehicle was safed with no apparent other issues. SpaceX and NASA are now looking at the next launch window, which is on Tuesday, May 22 at 0744 UTC, 3:44 EDT. Computer checks all launch components just prior to launch, which is an extra safety feature of the Falcon 9, so the good part of the abort is knowing that all the systems worked as designed to prevent a liftoff that wasn’t within the designed parameters. Since this is a test flight, the SpaceX team likely thinks of this a successful launch abort as opposed to a failed launch.

See the video below:

“I have watched and participated in more scrubs of the shuttle than I would have liked, but it’s just part of the launch business,” said Michael Lopez-Alegria, former shuttle and ISS astronaut and President of the Commercial Space Federation. “I was extremely impressed with professionalism displayed by the SpaceX launch team in the moments after the scrub to safe the vehicle. We will have to wait for the team to perform the technical analysis of what caused the apparent high pressure in one of the engine’s combustion chambers and for SpaceX and NASA to decide when the next attempt will occur. This is not the outcome we were hoping for, but far better to detect and react to the problem while still in the pad than to have to deal with it in flight.”

When launched, Dragon will be the first commercial spacecraft to go to the International Space Station for cargo resupply.

We’ll have more details later, as SpaceX and NASA will have a press briefing later this morning.

Launch Day Timeline for SpaceX’s Dragon

Saturday morning’s launch window for SpaceX’s historic test flight to the International Space Station lasts just one second. Company President Gwynne Shotwell predicted they have “better than a 50-50 shot on whether we lift off tomorrow,” she said at a press conference today, adding, “If we lift off, we’ll get to orbit.”

Shotwell and NASA officials outlined a myriad of systems and activities that have to go perfectly for the launch take place, and then it will be non-stop action for the duration of the flight to orbit and ultimately the berthing of Dragon to the ISS.

Launch is set for 08:55 UTC on May 19 (4:55 AM Eastern/1:15 AM Pacific.) Here’s a timeline of activities so you can follow along while you watch the launch:

08:45 UTC: The Terminal Count begins at T-10 minutes before launch

08:52:30 (T-00:02:30) SpaceX Launch Director verifies GO

T-00:00:03 Engine controller commands engine ignition sequence to start

08:55: Liftoff

T+0:02:58 1st Stage Shut Down (Main Engine Cut Off)
T+0:03:02 1st Stage Separates
T+0:03:09 2nd Stage Engine Start
T+0:09:00 2nd Stage Engine Cutoff

09:04:34 (T+0:09:35) Dragon separates from Falcon 9 and initializes its propulsion system.

09:06:30 (T+0:11:30) Deploy solar array

09:08 (T+0:13) On-Orbit Operations begin

Shotwell said that 2 hours and 26 minutes into the flight is the Guidance Navigation and Control (GNC) door is opened on the exterior of the capsule. “This is a key new feature for this mission, which basically exposes the Proximity Operations Sensors to space so we can see the ISS as we are approaching and allow us to get close enough to berth,” Shotwell explained. “Our star trackers also get a view of space at this time, so this is a very critical operation”

The first 24 hours into the flight, Dragon will be catching up or phasing with the ISS. On Flight Day 2 at about 40 hours into the flight, Dragon will the ISS and do a “flyunder” of the station and for about 10 hours, do some maneuvers to demonstrate the ability to stationkeep and fly about the ISS, all the while in contact with the space station and Mission Control. There will be a relative GPS demonstration, and the “critical operations and tests we need to execute and show NASA the data so that we can show them everything is working,” Shotwell said.

Then, Dragon will perform a re-rendezvous with a flyunder of about 2.5 kilometers below the station, then maniever in front of the station, raise up and go back around.

Don Pettit and Andre Kuipers will be working Canadarm2 on the station, and will grapple Dragon on May 22, berthing it to the Harmony node.

If there are any problems, NASA, SpaceX and the crew on the ISS has the ability to call an abort, or Dragon could autonomously abort.

But everyone is hoping for smooth sailing.

“By hour 75, if all is going well, we should be berthed to the station, which should be really great,” Shotwell said. “I know everyone at SpaceX is excited for this mission.”

The SpaceX launch webcast is scheduled for 1:15 AM Pacific / 4:15 AM Eastern / 08:15 UTC on May 19 at the SpaceX website, or you can watch on NASA TV starting at 08:30 UTC.

Right now the weather looks favorable for launch. If SpaceX can’t launch on the 19th, they can try again On May 22, 25th and 29th, which provide good launch opportunities. Other less than optimal dates for launch are the 23rd, 26th, and then the ISS enters into a period of high beta angle of the Sun, where there would be excessive heat surrounding the station, so the 29th of May is last date for awhile that SpaceX could launch Dragon.
