SpaceX Successfully Launches Cargo Ship to Station and Hard Lands Rocket on “Drone Ship”

SpaceX successfully launched their commercial Falcon 9 rocket and Dragon cargo ship on a critical mission for NASA bound for the space station this morning, Jan. 10, while simultaneously accomplishing a hard landing of the boosters first stage on an ocean-floating “drone ship” platform in a very good first step towards the bold company goal of recovery and re-usability in the future.

The spectacular night time launch of the private SpaceX Falcon 9 rocket lit up the skies all around the Florida Space Coast and beyond following a flawless on time liftoff at 4:47 a.m. EST from Cape Canaveral Air Force Station.

The nine Merlin 1D engines of the 208 foot-tall Falcon 9 generated 1.3 million pounds of liftoff thrust as the rocket climbed to orbit on the first SpaceX launch of 2015.

The Dragon CRS-5 mission is on its way to a Monday-morning rendezvous with the International Space Station (ISS).

It is loaded with more than two tons of supplies and NASA science investigations for the six person crew aboard the massive orbiting outpost.

A secondary goal of SpaceX was to conduct a history-making attempt at recovering the 14 story tall Falcon 9 first stage via a precision landing on an ocean-going landing platform known as the “autonomous spaceport drone ship.”

SpaceX CEO Elon Musk quickly tweeted that good progress was made, and as expected, more work needs to be done.

This was an experiment involving re-lighting one of the first stage Merlin engines three times to act as a retro rocket to slow the stages descent and aim for the drone ship.

“Rocket made it to drone spaceport ship, but landed hard. Close, but no cigar this time. Bodes well for the future tho,” Musk tweeted soon after the launch and recovery attempt.

“Ship itself is fine. Some of the support equipment on the deck will need to be replaced…”

“Didn’t get good landing/impact video. Pitch dark and foggy. Will piece it together from telemetry and … actual pieces.”

Musk’s daring vision is to recover, refurbish and reuse the first stage and dramatically reduce the high cost of access to space, by introducing airline like operational concepts.

The ‘autonomous spaceport drone ship’ was positioned some 200 to 250 miles offshore of the launch site in the Atlantic Ocean along the rockets flight path, flying along the US Northeast coast to match that of the ISS.

The autonomous spaceport drone ship measure only 300 by 100 feet, with wings that extend its width to 170 feet. That’s tiny compared to the Atlantic Ocean.

Therefore the SpaceX team was successful in accomplishing a rocket assisted descent and pinpoint landing in the middle of a vast ocean, albeit not as slow as hoped.

No one has ever tried such a landing attempt before in the ocean says SpaceX. The company has conducted numerous successful soft landing tests on land. And several soft touchdowns on the ocean’s surface. But never before on a barge in the ocean.

So they will learn and move forward to the next experimental landing.

CRS-5 marks the company’s fifth resupply mission to the ISS under a $1.6 Billion contract with NASA to deliver 20,000 kg (44,000 pounds) of cargo to the station during a dozen Dragon cargo spacecraft flights through 2016 under NASA’s Commercial Resupply Services (CRS) contract.

“We are delighted to kick off 2015 with our first commercial cargo launch of the year,” said NASA Administrator Charles Bolden in a statement.

“Thanks to our private sector partners, we’ve returned space station resupply launches to U.S. soil and are poised to do the same with the transport of our astronauts in the very near future.”

“Today’s launch not only resupplies the station, but also delivers important science experiments and increases the station’s unique capabilities as a platform for Earth science with delivery of the Cloud-Aerosol Transport System, or CATS instrument. I congratulate the SpaceX and NASA teams who have made today’s success possible. We look forward to extending our efforts in commercial space to include commercial crew by 2017 and to more significant milestones this year on our journey to Mars.”

The Dragon CRS-5 spacecraft is loaded with over 5108 pounds (2317 kg) of scientific experiments, technology demonstrations, crew supplies, spare parts, food, water, clothing, and assorted research gear for the six person crew serving aboard the ISS.

The launch marked the first US commercial resupply launch since the catastrophic destruction of an Orbital Sciences Antares rocket and Cygnus Orb-3 spacecraft bound for the ISS exploded unexpectedly after launch from NASA Wallops, VA, on Oct. 28, 2014.

The US supply train to the ISS is now wholly dependent on SpaceX until Cygnus flights are resumed hopefully by late 2015 on an alternate rocket, the Atlas V.

    Straight up and down. Just like God and Robert Heinlein intended.

    This is the first article about this launch I’ve read today that doesn’t start with the word ‘failure.’ Every other news outlet I’ve read this morning called it a failure in the first sentence if not the headline, adding a small by-the-way the ISS cargo is on it’s way too. In the week leading up to today’s launch, many news sites had already decided the primary mission was to land on a barge, instead of it being an interesting secondary goal worth watching. This flight is a success on so many levels. So thanks to the author and Universe Today for publishing this story the way you did.

    launch delays – check; safety first
    successful launch – check
    cargo enroute to ISS – check
    falcon 1st stage return to ocean landing barge – check
    intact landing – no joy; observe, learn, try again

      Depends on the word “Hardlands”.

      I guess a lot of people were anxious about the landing, making it more of a opener about its succes or failure.
      When it becomes the norm, the landing will become just secondary info. Although …it will still be value loss …

  3. Congratulations on the successful launch! (if they got good data from the first stage, then the landing was a success as well)
    My daughter Heather wanted to know when watching the live feed on SpaceX TV, what was that shot of what looked like bubbled liquid floating in near zero gravity? Was that the inside of the fuel tank?

    • Robert says:

      I also wondered if it was the inside of a fuel tank. ? SpaceX ???

      • Jim E says:

        Looks like a fuel (or possibly liquid oxygen) tank on the second stage, looking down from the top. You could see it was approaching empty when the second stage shut down, then the remaining fuel (O2?) floated around as blobs. When rockets need to restart in weightless conditions, it’s usual to run the thrusters for a few seconds to get the fuel back to the bottom of the tanks before the restart.

      • Thanks Jim (and Robert) I’ll let her know. I was wondering about the “blobs” myself.
        She also said (and I agree) that “That would make a cool screen saver!”

  4. Aqua4U says:

    I find it hard to believe they didn’t get video of the landing attempt. You’d think they’d have had IR or night vision camera’s everywhere? Regardless… “If at first you don’t succeed… try, try again!”

    Je suis charlie!

    • Robert says:

      The night vision stuff might present difficulties when dealing with the rocket’s very hot + bright exhaust plume in close proximity to what ever else you wanted to observe.
