Success: Dragon has been captured and is now docked with ISS.
Dragon’s dress rehearsal rendezvou last night was a success, and the spacecraft has been cleared to proceed with berthing tomorrow morning.
Dragon’s test rendezvous with ISS tonight has begun.
The rendezvous won’t be completed until 6:30 am (Eastern), with two orbital engine burns scheduled for 3 and 4 am. For further updates you can go here. Or you can watch everything on NASA TV.
Dragon has been approved to approach within 1.5 miles of ISS tonight in its first rendezvous test. More information here.
If this goes well tonight, Dragon will next attempt to approach the station close enough for its robot arm to grab it.
Not surprisingly, last night’s successful launch of Falcon 9 has produced a large number of news articles. Rather than list them all, go to spacetoday.net for the links.
However, I think Clark Lindsey, in describing Elon Musk’s reaction to the successful launch, captured the most important aspect of last night’s success:

Falcon 9 has cleared the tower and is “looking good.”
First stage has completed its job and has been released. The second stage is firing as planned.
Dragon has separated from the second stage and is now in orbit. Now comes the real test of this mission: Can Dragon maneuver and rendezvous with ISS?
The best moment for the entire launch sequence was when Dragon’s solar arrays deployed. The camera link was still working, so that everyone could see it. When the arrays locked open, there was a gigantic roar from the crowd of people watching at SpaceX’s mission control. Dragon was in orbit and operational!
Tonight’s Falcon 9 launch: The countdown has begun, and the weather conditions have improved.
SpaceX will begin its own webcast at 3 am (Eastern), which is midnight here in Arizona.
An aside: The ashes of actor James Doohan, who played Scotty on the 1960s television show Star Trek, will be among 308 other cremated remains launched into space by Falcon 9 tonight. As one commenter for the above article noted quite appropriately,
You haven’t really covered any of the important questions here.
i.e. Are there enough dilithium crystals in the engine room to get Scotty up there? And are they using photon torpedoes to blast him out into space? And when they launch, will someone say, “Take her out, Mr. Sulu. Warp factor one.”?
Godspeed, Scotty old bean.
The Falcon 9 launch tonight is a go, with weather 80 percent favorable.
In an email update, SpaceX reports that they have found the cause of the Falcon 9 launch abort this morning.
During rigorous inspections of the engine, SpaceX engineers discovered a faulty check valve on the Merlin engine. We are now in the process of replacing the failed valve. Those repairs should be complete tonight. We will continue to review data on Sunday. If things look good, we will be ready to attempt to launch on Tuesday, May 22nd at 3:44 AM Eastern.
If this is true, than this entire exercise is an unqualified success and illustrates a certain robustness to SpaceX’s engineering on Falcon 9. Their control computer during the launch process spotted the problem before it caused a complete loss of the vehicle and payload. They can now locate the problem, fix it, and proceed with launch.
The Soyuz spacecraft with three astronauts has docked successfully with ISS.
Barring weather or another launch scrub, it looks like Saturday will be launch day for Falcon 9 and Dragon
An overview of what will happen on Dragon’s first flight to ISS next week.
Hitching a ride: The Russians last night launched a new crew to ISS.
Next up: the launch of Falcon 9/Dragon on Saturday.
The SpaceX test launch of Dragon to ISS has now been rescheduled for May 19.
The test flight of Falcon 9/Dragon to ISS will almost certainly not launch on May 7.
It appears they need more time to assess the results of the static engine test on Monday.
In closing down its ATV cargo freighter assembly line, Europe considers its next manned space project.
ESA and NASA have been discussing how ESA might compensate NASA for Europe’s 8.3 percent share of the international space station’s future operating charges. Until about 2017, the agency is repaying NASA, as the station’s general contractor, through launches of European Automated Transfer Vehicle (ATV) cargo ships to the station. But with the station partners now all but committed to operating the station at least through 2020, ESA is searching for another “barter element” to succeed ATV.
NASA has said a propulsion module for the Orion Multi-Purpose Crew Vehicle would fill ESA’s obligations to NASA, which have been estimated at about 450 million euros ($600 million) over three years.
But several ESA members, notably France and Italy, have argued that the Orion module, which would use ATV-derived technologies, does not provide sufficient technology interest or public impact. Instead, these governments have proposed development of a vehicle that would perform multiple tasks in low Earth orbit, including debris removal.
Want to watch the launch of Falcon 9/Dragon? Here’s the low down.
Three astronauts have returned safely to Earth in their Soyuz capsule after spending 165 days on ISS.
SpaceX and NASA have now set May 7 as the planned launch date for the Dragon test flight to ISS.
SpaceX has delayed the launch of its Dragon test mission to ISS, with the launch now scheduled sometime between May 3 and May 7.
“After reviewing our recent progress, it was clear that we needed more time to finish hardware-in-the-loop testing and properly review and follow up on all data,” SpaceX spokeswoman Kirstin Brost Grantham wrote in an email. “While it is still possible that we could launch on May 3rd, it would be wise to add a few more days of margin in case things take longer than expected. As a result, our launch is likely to be pushed back by one week, pending coordination with NASA.”
Orbital Sciences has released an updated launch schedule for its Antares rocket and Cygnus capsule.
The significance?

ISS’s robot arm has now been moved into position in preparation for the Dragon berthing flight, scheduled for April 30.
The article also gives a nice outline of the entire Falcon 9/Dragon test flight.
Mark your calendar: Decision day for the SpaceX Falcon 9/Dragon test flight on April 30 will be April 16.
The universe as seen by astronauts on ISS.
Is this good or bad news? Europe has shut down the production line producing their ATV cargo craft for ISS.
Confronted by parts obsolescence and waning political support, the European Space Agency has shut down subsystem production lines for the Automated Transfer Vehicle as member states debate how they will contribute to future international space exploration efforts, according to top spaceflight officials.
ESA has launched three of the five ATVs it agreed to launch, with the remaining two scheduled in 2013 and 2014. What happens after that remains unclear. It seems from the article the European partners don’t seem interested in upgrading the ATV, and instead seem willing to let the as-yet untried U.S. commercial companies carry the load.
Commercial flights by U.S. spacecraft will make up the rest of the lost capacity with the end of the ATV program.
The pressure continues to build on a successful Falcon 9/Dragon flight on April 30.
The NASA administrator, Charles Bolden, has balked at the Europe-China negotiations for docking a Chinese manned craft at ISS.
I don’t know what Bolden can do about this, however, as we don’t have the ability to get to our own space station, while Europe and the Chinese do.
Europe’s ATV freighter has successfully docked with ISS.
The story describes how Boeing is considering upgrading the X-37B to become a manned ferry to ISS, thus putting it in direct competition with the company’s other manned capsule, the CST-100.
At the American Institute of Aeronautics and Astronautics’s Space 2011 conference in November, Boeing’s Arthur Grantz revealed that the company is studying a new derivative of the Boeing/USAF X-37B. The new X-37C would be 65-80% larger than the current B version. Launched by an Atlas V rocket, X-37C could carry pressurized or unpressurized cargo or 5-6 astronauts. Grantz is chief engineer in charge of X-37 at the Boeing Space and Intelligence Systems Experimental Systems Group .
Hat tip to Clark Lindsey.
The six astronauts on ISS will take shelter in the two Soyuz capsules tonight because a piece of space junk will to pass close to the station at around 2:30 am (Eastern).
In discussions the last two days, managers for the space programs of Europe and China began laying the groundwork for a Chinese docking at ISS.
The United States, which paid for and built the bulk of ISS, has no way of getting its own astronauts to the station. The United States at present also has no way to bring cargo up to the station.
The result: We no longer own our own space station. Though the U.S. has strict laws on the books to prevent the transfer of technology to the Chinese, restricting communications by government officials with China, the Europeans do not. And since they can send cargo to ISS while we cannot, they feel free to negotiation with the Chinese for the use of our space station. Moreover, the Russians I am sure will heartily endorse these negotiations.
And what can the U.S. government do? Nothing.
Instead of focusing on a solution to this situation, the members of Congress tasked with supervising NASA want NASA to build a giant heavy-lift rocket (SLS) to use with the Orion capsule, neither of which is designed to go to ISS. Moreover, neither will be capable of flying humans into space until 2021, one year after ISS is presently scheduled to be shut down. Even then a single flight will cost billions, which makes this system useless for resupplying ISS.
And people wonder why I consider these elected officials stupid. And if they aren’t stupid, they surely are irresponsible and incompetent, at least when it comes to the American space program.
