Oblique image of Copernicus taken in 1966

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.

At a conference in Washington DC yesterday both Russia and Japan announced the Moon as their next primary space exploration goal.

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.

Falcon 9 has cleared the tower

12:46 am

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!

The countdown has begun

9:37 pm

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.

SpaceX has reported that they have found the cause of the Falcon 9 launch abort this morning.

4:46 pm

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.

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.

An engineer has proposed in great detail building the USS Enterprise for the purpose of exploring the solar system.

8:58 am

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.

The website is Build the Enterprise.

The assembly of the first test vehicle of XCOR Aerospace’s Lynx suborbital craft has begun.

The competition heats up: The assembly of the first test vehicle of XCOR Aerospace’s Lynx suborbital craft has begun.

I will admit to great deal of skepticism about this particular space company. Somehow XCOR always manages to get a great deal of coverage in the space community press, despite what I see as lack of any actual space-related results.

I could be wrong however, and if so, I will be the first to celebrate. This article suggests they might finally start test flights by the end of this year.

SpaceShipTwo to resume flight tests in June after a nine month hiatus.

SpaceShipTwo to resume flight tests in June after a nine month hiatus.

The long pause in flight tests, as well as the apparent delays in flying the ship with its rocket engine, suggest that there have been engineering issues with the ship and engine that Scaled Composites hasn’t revealed. Hopefully the resumption of testing is an indication that these issues have been overcome.

ATK today announced that it is building its own manned capsule for its Liberty solid rocket.

6:58 pm

The competition continues to heat up: ATK today announced that it is building its own manned capsule for its Liberty launch system.

The capsule’s first two flights are scheduled in 2014, both abort tests, followed in 2015 by an orbital flight and, finally, a crewed orbital flight. The spacecraft is designed for ten flights each, and ATK plans to build a minimum of four capsules. All flights will be launched by the Liberty launcher, and ATK is not actively exploring adapting the capsule for other [launch vehicles].

Liberty is based on the upgraded shuttle solid rocket boosters that were developed for the Ares rocket, now cancelled.
