Dennis Wingo has written a detailed report on the engineering analysis of ISEE-3, including what they plan to do on Wednesday to troubleshoot the problem and possible fix it.
The bottom line is that there is still a good chance they can get the spacecraft thrusters to fire and change the spacecraft’s trajectory. We will know more tomorrow.
The ISEE-3 team will attempt a plumbing repair on ISEE-3 on Wednesday.
They say that further details will follow. If it works, however, they will immediately try to fire the spacecraft’s thrusters to get it into the right orbit for future science operations.
The competition heats up: DARPA has announced contract awards to three companies for the construction of its experimental XS-1 spaceplane, designed to take off and land like a airplane.
The contracts go to Boeing, Northrop Grumman, and Masten Space Systems, and have them each respectively partnered with Blue Origin, XCOR, and Virgin Galactic. More details on the Boeing contract can be found here.
The description of the XS program is quite exciting:

The competition heats up: More information was released today describing Great Britain’s suggested spaceport locations.
These spaceports are specifically aimed at the suborbital space tourism market, for American companies like Virgin Galactic or XCOR, or for the developing British company Skylon.
It is interesting that 6 of 8 are located in Scotland, which might very well not be part of the United Kingdom after a vote on separation this fall.
The competition heats up: Russia has set September 28 as the next launch date for its troubled Proton rocket.
The most interesting detail gleaned from this article however is this:
The Proton-M carrier rocket previously launched on May 16 from Baikonur space center collided with communications satellite Express ΠΠ4R and burned up in the atmosphere above China, leaving Russia without its most powerful telecommunications satellite.
Previous reports had not been very clear about the causes of the May launch failure. All they would say is that “a failed bearing in the steering engineβs turbo pump” had caused the failure about nine minutes into the flight. This report suggests that this failure occurred after separation of the payload and that it then caused the upper stage to collide with the satellite.
Russia is also about to ship its new Angara 5 rocket to the launch site for a planned December launch. This will be the first launch of the Angara configuration that is expected to replace the Proton rocket, and is expected to place a dummy payload into geosynchronous orbit.

The competition heats up: SpaceX’s Falcon 9 has successfully launched six Orbcomm commercial satellites into orbit.
The six satellites still must be deployed. We will know if this is successful sometime in the next hour or so. Also, no news yet on SpaceX’s effort to recover the rocket’s first stage after a soft splashdown in the ocean.
Update: All 6 Orbcomm satellites have successfully deployed.
Update 2: From Elon Musk as to the first stage recovery: “Rocket booster reentry, landing burn & leg deploy were good, but lost hull integrity right after splashdown (aka kaboom).”
The competition heats up: The government of the United Kingdom today outlined its intention to build its first spaceport by 2018.
The announcement listed eight potential sites, six of which were in Scotland, which is presently threatening to break away from the United Kingdom. This announcement I suspect is less a call for British space exploration and instead a political effort to encourage Scotland to remain in the UK.
All is go for a 12:52 pm launch of Cygnus’s second operational cargo flight to ISS.
If you live on the east coast of the U.S. you should be able to see some part of this launch when it happens.
Cygnus has lifted off.
The main engine has cut off and the first stage has successfully separated.
The second stage has ignited successfully. It has now completed its burn and has separated from the spacecraft. Cygnus is in orbit.
The competition heats up: The Air Force today certified that SpaceX’s Falcon 9 rocket had completed three successful flights.
This certification is a preliminary okay before the official certification. What it means is that the Air Force is agreeing that the Falcon 9 is capable of launching its satellites, which also means that the official certification is almost certain.
The competition heats up: The new budget of India’s new conservative government under Narendra Modi has given its space program a 50 percent increase.
It appears that there were increases across the board, including a gigantic increase for their GSLV rocket as well as their manned program.
It also appears that Modi is following in the path of George Bush, at least when it comes to space. He might be a conservative, pro private enterprise and anti-big government, but his approach to building a space industry is decidedly Soviet in style, pumping funds into government agencies so that they can build the rockets and spacecraft. For the moment at least, private companies will be the servants to India’s government space program, not the masters.
In the U.S. and Russia this approach worked for the first generation of rockets and spacecraft, but then ended up a lead weight for later generations. I suspect we shall see the same history play out in India.
The competition heats up: A Soyuz rocket successfully launched four communications satellites from French Guiana yesterday.
I know that I repeatedly pound Arianespace for its high costs and lack of profits, but anyone who thinks this European company, in partnership with the Russians, is going to let its competition grab its customers easily is in for a surprise. They are going to fight back, and have the resources to do it.
The battle is on! It should be a lot of fun to watch over the next decade.
Because the severe weather conditions at Wallops Island have interfered with preparing Antares and Cygnus for launch, Orbital Sciences announced today another 24 hour launch delay, rescheduling it now for Sunday, July 13, at 12:52 pm (Eastern).
