At a joint press conference with NASA earlier today, SpaceX CEO Elon Musk said the company will try a water landing of its Falcon 9 first stage later year.
The landing will be the start of a series of flight tests that could culminate with an attempted propulsive landing of a first stage back at its launch site in the middle of 2014, Musk said.
During the initial test, the first stage will continue on a ballistic arc and execute a velocity reduction burn to cushion its re-entry into the atmosphere, the SpaceX chief said. Just before splashdown, the rocket will light up its engines again.
Musk said he expected to lose first stages during the initial recovery attempts. The company is looking to gain the experience and data needed to bring a first stage back to the launch site next year for a propulsive landing using retractable legs. He said that attempt could occur in mid-2014.
SpaceX also plans to unveil upgraded versions of the Falcon 9 and its Dragon freighter later this year. The improved rocket includes more powerful engines, longer fuel tanks and a number of significant upgrades that will improve its capability by 60 to 70 percent, Musk said.
Dragon version 2 will be able to carry more cargo and include larger windows for use in later crewed versions of the vehicle. The upgraded Dragon also will feature powerful, side-mounted thruster pods as well as retractable landing legs that will allow for propulsive touchdowns on land.
Musk expects that water landings will become a thing of the past, and that touching down on land will allow the company to conduct missions at a more rapid pace. He did not give any timetable for the first ground landing attempt.
The SpaceX CEO made his remarks during a post-mission press conference for the recently completed Dragon resupply mission to the International Space Station. Joining Musk at the event were SpaceX President Gwynne Shotwell, NASA Administrator Charles Bolden, and International Space Station Program Scientist Julie Robinson.
A full synopsis of the press conference is below.
Opening Remarks
Bolden: •We’re really pleased at working together that SpaceX and NASA teams were able to berth at station and return safely
•Importance of the commercial cargo program and how critical it is for the ISS program
•Orbital Sciences is other COTS partner – set for a test flight of Antares rocket in April
Shotwell:
•Three successful missions in three months –
•First operational mission with Dragon trunk – grapple bars
•A number of technological demonstrations on this mission
•Dragon back in port in Long Beach last night at about 7 p.m.
•All systems remain powered and NASA received all critical cargo
•Returned 3,256 lbs. of cargo – 200 lbs. more than originally planned
Musk:
•Had an issue with Dragon spacecraft briefly
•Slight issue with propellant test valve
•Fixed within four or five hours
•No further issues after that point
•We don’t expect to see that issue again
Robinson:
•Over 200 scientific investigations ongoing on ISS
•Variety of different types of experiments
•300 tubes of blood – studying interaction between nutrition and bone loss — applications for osteoporosis treatment
•Experiment looking at alloy mixtures – launched on Dragon and returned
•Agriculture education, commercial activities
•Samples are on the ground, researchers are beginning to look at them
Q&A Session
Q. When is next CRS launch?
Shotwell: CRS 3 launch late this fall. A number of upgrades to the Dragon configuration that will enable better critical cargo to be sent and returned.
Musk: Will include upgraded Falcon 9. Could increase the useful payload of Dragon by several tons. As much as you could pack into Dragon.
Will attempt to recover the first stage.
“As I said before, I think it will take us several flights before we are successful in that.”
Q. Fairing test status at NASA Plum Brook?
Musk: NASA Plum Brook is an “really, epic super cool” facility
Prepping to do separate tests. Will be releasing information on it in the next few weeks.
Q. Are you optimistic about Orbital Sciences tests going on as scheduled?
Bolden: “Yes”
Q. When will Dragon be ready for human spaceflight and are they still on track for 2015?
Musk: “Things seem to be going very well.” Hitting milestones and hope to do pad abort tests later this year. “It’s coming along really well.” Partnership with NASA is going very well.
Bolden: All of our partners are making very good progress and making their milestones under CCiCAP agreements. The partners are also involved in developing certification process and showing they meet the requirements that are laid out.
NASA is the long pole in the tent. Hope to put out an RFP next spring with down select for providers in Fall 2014. Depends upon how generous Congress is with funding the program.
Q. What was the problem with the thrusters on Dragon?
Musk: There was a “very tiny change” to three of the check valves on the oxidizer tank. Different from the previous ones that flew, and they got stuck. Was able to write some new software in real time that was uploaded with Dragon to increase pressure upstream from check valve and release it. The spacecraft version of the Heimlich maneuver. Once they got unstuck, they worked very well.
Had difficulty communicating with the spacecraft because it was drifting. Worked with the Air Force to get higher powered dishes to communicate with Dragon and upload the software.
Q. How will sequestration affect commercial crew?
Bolden: As we projected, sequestration has a detrimental impact on the commercial crew program by reducing the amount of money available for partners. Don’t see an impact for the rest of this fiscal year (ends September 30), but it will have an impact down the road unless NASA gets more funding.
Q. What is long-term solution for Dragon thruster problem?
Musk: The software uploaded was to get the valve unstuck. We need to fix this tiny little issue with the valve, reverting it to was it used to be. Will do some checks to make sure it doesn’t happen again.
Q. What is strategy on booster recover?
Musk: Initial recovery test will be a water landing. First stage continue in ballistic arc and execute a velocity reduction burn before it enters atmosphere to lessen impact. Right before splashdown, will light up the engine again. Emphasizes that we don’t expect success in the first several attempts. Hopefully next year with more experience and data, we should be able to return the first stage to the launch site and do a propulsion landing on land using legs.
Q. Is there a flight identified for return to launch site of the booster?
Musk: No. Will probably be the middle of next year.
Q. What are long term effects of sequestration?
Bolden: We don’t see an impact for the rest of 2013 calendar year because we ended up with more money than expected in commercial crew. Already discussing delays in commercial crew milestones with partners. Sequestration is a 10-year program that was never supposed to be executed.
Q. What was Bolden’s reaction to SpaceX’s solution to the propulsion problem?
Bolden: Incredible to watch their young, energetic team work through the propulsion anomaly.
Musk: SpaceX and NASA teams are deeply integrated and working closely with each other. It’s great to work with NASA. NASA was so cool, I was far more anxious than NASA was. We have one cool customer.
Q. On the check valve problem, you characterized it as a tiny issue. Was it a manufacturing or a configuration question?
Musk: It was a tiny design revision change from the supplier. The supplier made some mistakes and we didn’t catch those mistakes. Ran system through low pressurization tests, but didn’t run them through the high presssurization functionality tests. Didn’t get stuck in the low pressurization functionality tests. Make sure we don’t repeat that in the future. Need a magnifying glass to see the difference.
Q. How is upgraded Falcon 9 different from the current version?
Musk: Next version is a meaningful upgrade. Has 60 to 70 percent more capability. Improved redundancy, structure, engines, avionics, etc. This version is designed to allow first stage to land propulsively back at the landing site. Will take at least a year to get that right.
Shotwell: Performance changes are more than rocket changes, but translate into an improvement for scientific community. Can bring up more powered cargo, refrigerators, etc.
Musk: Dragon version 2 will be a significant upgrade, with the capability to land propulsively on land. Water landings will become a thing of the past. Will allow for missions at a faster tempo.
Q. Can you provide more details on Dragon Version 2?
Musk: Significant upgrades, powerful side mounted thruster pods. Quite big windows for astronauts to see outside. Landing legs that pop out of the bottom. It look like kind of a real alien spaceship. Started with landing on water because it was the easiest thing to do and we didn’t really know what we were doing. Didn’t want to take any unnecessary risks. Now want to push the envelope on the technology.
Plan to unveil Dragon Version 2 later this year.
Final Comments
Shotwell: Thanks all the SpaceXers for all the hard work they put in. Thanks NASA as both a partner and customer, extraordinary relationship with them. Thanks the Air Force, FAA and FCC.
Robinson: A real consolidation between commercial transport and the use of ISS for commercial research. All these things are going hand in hand, and they’re bringing results back to the U.S. economy.
They already have reached the ISS twice in a row. Since they aren't planning to go to Saturn anytime soon, I'll settle for when they start taking business away from the Europeans, Russians, Indians, and Chinese.
Boeing, Lockheed, Northrup Grumman, Space X. What’s the difference?
What Spacex is doing is cool but at what cost? I strenuously object to the way they are getting funded at the expense of thousands of engineers with a proven record. Of course those engineers just tended to be conservative and from states which don’t support Obama.
Sure NASA has made mistakes, heck they still employ Hansen, but they’ve done and are doing some incredible awe inspiring things.
They barely made orbit twice in a row.
I understand that, but how much have they done that is commercialized?
Doing science, for the sake of science, is great in theory.
“Boeing, Lockheed, Northrup Grumman, Space X. What’s the difference?”
SpaceX is run by an Obama bundler.
” I know the problem with the foam heat shields, that destroyed Columbia, were due to NASA being ordered to be green.”
Those deaths need to be laid at the doorstep of the EPA.
“I understand that, but how much have they done that is commercialized?”
You’re joking right? The technologies developed by NASA and associated commercial organizations effect every aspect of our lives.
How much payload will Musk sacrifice in order to land his rocket? Gravity isn’t cheap. It will take a good bit of fuel to land that first stage. That fuel will come at the expense of payload.
BTW, NASA has been building and launching rockets for 50 years. What they have learned, they turn over to private industry. You know, people like Elon Musk and SpaceX.
Musk rubbed a LOT of people the wrong way by not giving credit to the people who figured out all of this space flight stuff.
All he is doing is refining what was discovered 40-50 years ago.
But he’s doing it in such a cool way
“Musk: It was a tiny design revision change from the supplier. The supplier made some mistakes and we didn’t catch those mistakes. Ran system through low pressurization tests, but didn’t run them through the high presssurization functionality tests. Didn’t get stuck in the low pressurization functionality tests. “
Quality control mistakes and inadequate testing are unacceptable when you have lives and billions of dollars at stake. They’ll be forced to add the same overhead NASA has been forced too.
Yeah, like that cool Tesla?
Musk is a salesman first, engineer second. He has already figured out how to seperate people (the US government) from their money (taxes money).
Everyone hears “SpaceX” and they think “private commercial”. They would be shocked to know how much money he has received in government contracts.
And the others aren't? Are you kidding me? They buy petrolum jelly in 55 gallon drums for use in Washington, DC and surrounding areas.
Difference is SpaceX didn't do a paper spacecraft. They are building hardware that mostly works a whole lot cheaper than all of the above.

You’re ok with Obama cronies getting sweatheart deals while the govt is forced to GIVE him data, designs, and technical support?
Really?
And no, the thousands of engineers in Texas and Florida who have been put out of work by this are not Obama fans.
That kind of crap is the difference between the F-22 and the WWII era warplanes. Fly then fix costs lives. So be it.
Fix then fly means you stay on the ground.
I despise that crap. It's institutionalized thinking.
And even with the billions and billions NASA spent on quality control and testing, they managed to kill a lot more folks than Musk has.
It's a dangerous business.

Instead of reducing payload, they are making the rocket bigger. Notice they are talking about the Falcon 2 upgrade. I think about 1/3 of the fuel in the rocket will be used to return to the pad.
BTW, NASA has been building and launching rockets for 50 years. What they have learned, they turn over to private industry. You know, people like Elon Musk and SpaceX.
Yes, as they should.
You can do it with a spitfire.
With a system more complicated you end up with mission failure.
