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.
No more banging that ketchup bottle: Engineers at MIT have developed a coating for the insides of food containers that will allow all the food to flow out.
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.
The new colonial movement: At a conference in Washington DC yesterday both Russia and Japan announced the Moon as their next primary space exploration goal.
If the U.S. gets a competitive private aerospace industry going — which seems increasingly likely — I’m willing to bet those companies will get to the Moon before either of these governments.

Several key elected officials who have generally been hostile to commercial space have commented positively to the successful launch of the Dragon capsule last night.
First, Senator Kay Bailey Hutchison (R-Texas) released this short statement:

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:

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.
The competition heats up: Boeing has unveiled a design to put small satellites into orbit for as little as $300,000 per launch.
SpaceX is set to begin the countdown tonight for a 3:44 am (Eastern) May 22nd launch of Falcon 9/Dragon.
An evening pause: Bridge Day 2011: An 800+ foot rappel from the New River Gorge Bridge in West Virginia. The event is held each fall, when they close the bridge to vehicles so pedestrians, base jumpers, and rappellers can enjoy it. I’ve done this rappel four times, twice as part of the safety team.
On the clip below, the rappel itself begins at 3:40. As this was this guy’s first rappel on the bridge, he takes it very slow, which is okay as it gives him time to enjoy the view.
An evening pause: A different kind of bridge, located in Russia and one that I wouldn’t speed across. Built originally as a railroad bridge to cross the Vitim River, it is 1870 feet long and about 50 feet above the water. Note how many of the cross planks are not attached.
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.
Last night Falcon 9’s computers shut the launch down at T minus zero seconds after sensing a high chamber pressure in one first stage engine.
Two thoughts, one good, one not so good.

No go: Falcon 9 aborted its launch tonight at 4:55 am (Eastern) at T minus zero seconds.
Just after ignition there was a shutdown. They were able to make the vehicle safe, and are trying to figure out what happened. It appears there was a high pressure reading in one engine.
The next opportunity to launch is three days hence, though whether they will go for it then depends on whether they can figure out what caused the shutdown.
Update: More details here.
The competition heats up: WhiteKnightTwo made its 80th flight yesterday.
Falcon 9 is now upright on launchpad for tomorrow morning’s 4:55 am (Eastern) launch. For continual updates, go here.
The competition heats up: Japan today launched its first commercial satellite.

Another Obama tech wonder company dies: LightSquared has filed for bankruptcy.
From the beginning engineers were saying that LightSquared’s system would interfere with GPS. The only reason the company lasted as long as it did was because it had the political backing of the Obama administration. And the reason it had that backing is because the company’s CEO was a big supporter of Obama.
Senator Bill Nelson (D-Florida) on Monday attacked the House version of NASA’s budget that required the agency to make a quick decision on its commercial manned launch company.
Nelson faces a difficult election campaign from the right. Thus, I suspect he has realized that he is better off promoting free enterprise than local pork. It is unfortunate that the Republicans in the House haven’t yet realized this.
Competition wins again: Faced with high prices and a near monopoly by China, the mining of rare Earth metals is once again rising worldwide.
How the predictions for the year 2000 changed throughout the 20th century.
Not surprisingly, Arthur Clarke’s predictions were generally the best.
If you build it they will come: An engineer has proposed using the USS Enterprise from Star Trek as a model for building an interplanetary spaceship for exploring the solar system.
Though similar in scale and appearance to the USS Enterprise (“it ends up that this ship configuration is quite functional,” Dan writes), the “Gen1 Enterprise” would be functionally very different. Firstly, the main nuclear-powered ion engine (boasting 1.5 GW of power) would strictly limit the Enterprise to intra-solar system missions, being incapable of anything approaching faster-than-light speeds. However, Dan claims that the Gen1 would be capable of reaching Mars from Earth within ninety days, and reaching the Moon in three.
