The Lunar Orbiter image of Copernicus Crater, taken forty-six years ago, has been re-released after significant refurbishing..
Reboot: The Lunar Orbiter image of Copernicus Crater, taken forty-six years ago, has been re-released after significant refurbishing.
By adding modern computer interfaces and data handling techniques, the LOIRP was able to scan and record the data in ways that simply could not have been accomplished in the 1960s. As a result the images that were obtained had a much higher resolution and dynamic range than had been seen to date. Indeed, in many cases, these images often rival or exceed images taken by the Lunar Reconnaissance Orbiter which is currently surveying the Moon.
You should definitely check it out, as it is a breathtaking image. Historic too, as it was the first image from the Moon that truly made the place understandable.

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.

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.

A rocket launch pushes Congress towards free enterprise
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:

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.

Bridge Day rappel
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.
The world’s most dangerous bridge?
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.
SpaceX has reported that they have found the cause of the Falcon 9 launch abort this morning.
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.

Some thoughts on the scrub
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.

Falcon 9 aborted its launch tonight at 4:55 am (Eastern) at T minus zero seconds.
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.

LightSquared has filed for bankruptcy
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.
