NASA Targets Monday for Earliest Launch Attempt of Endeavour
NASA To Work Issue Over the Weekend and Targets Monday for Launch of Endeavour, SpaceRef
"It will be 24 hours from the scrub time before technicians can access Endeavour's aft cabin Load Control Assembly (LCA). The LCA, a switchbox, is now where engineers think the problem is. By dinner time Saturday managers feel they will be able to start troubleshooting the problem after they've gained access to the LCA. Managers will meet Saturday night and Sunday morning to discuss progress on the issue. If they are to launch on Monday NASA will have to make that call no later than early Sunday afternoon so that by around 3 pm EDT they can begin preparations for launch."
Endeavour Launch Scrubbed for at Least 72 Hours
Space Shuttle Endeavour on Track for a 3:47 Launch
This morning at 6:22 p.m. EDT the loading of the space shuttle's external tank with 500,000 gallons of liquid oxygen and hydrogen began and the topping off of the tank's propellants will continue until launch time. All systems onboard Endeavour are functioning normally. There is a 70 percent chance of favorable weather for launch. The primary weather concern is for low cloud ceilings and crosswinds at the Shuttle Landing Facility.
8:53 am EDT Update: There is an issue which the KSC team is working with the pressure in the fuel tank in the right OMS pod, but they believe it can be corrected. They are trying a crossfeed between the OMS tanks.
9:40 am EDT Update: KSC is reporting that the OMS pressure issue has been resolved. Both left & right tanks are balanced & below pressure limits.
10:25 am EDT Update: The President is scheduled to arrive at KSC at 2:00 pm today.
12:30 pm EDT Update: We have a 48 hour scrub due to the failure of both heaters for Auxiliary Power Unit 1. A press briefing will be held later this afternoon to discuss the issue.
1:00 pm EDT Update: We NOW have a 72 hour scrub. NASA believes it has a problem in one of the load control assembly boxes, most like a short in that box or in the electrical lines to that box but won't know for sure until they can access the area and do detailed troubleshooting. They have to get into the aft of the orbiter and they'll first put in a platform set but the location is such that it will take some time to get to the load control assembly.
1:05 pm EDT Update:According to James Dean of Florida Today, President Obama will still visit KSC today.
1:30 pm EDT Update:The next launch attempt will be no earlier than
Monday at 2:33 p.m. EDT.
NASA Scrubs Space Shuttle Endeavour Launch at Least 72 Hours
"During today's countdown, engineers detected a failure in one of two heater circuits associated with Auxiliary Power Unit (APU) 1. Heaters are required to keep the APUs' hydrazine from freezing on orbit. Attempts to activate the heater were not successful and engineers now believe the problem might be associated with a Load Control Assembly, which is a switchbox, located in the aft end of Endeavour, or an electrical short in the wires leading into or out of the switchbox."
The shuttle crew left for the pad just minutes before the launch was scrubbed.
And minutes later before they reached the pad the crew turned around and head back to the Operations and Checkout Building.
Watching Endeavour From The Edge of Space
Space Shuttle Endeavour's Final Launch Inspires Hands-on Public Engagement
"When Space Shuttle Endeavour makes its final trip into space it will be under the watchful eye of a high altitude balloon built and flown by students and volunteers from across the U.S. This will be the second flight of a camera-equipped payload, the first having been successfully flown during in February 2011 when images were obtained of Space Shuttle Discovery's launch from a vantage point of over 100,000 feet. This balloon mission will be conducted by Quest for Stars, a non profit educational organization, in coordination with the Challenger Center for Space Science Education and the Coalition for Space Exploration."

As President Obama Marks Final Launch of Endeavour, Nation Looks to Commercial Space for the Future, Commercial Spaceflight Federation
"John Gedmark concluded, "We'll finally be able to realize the sci-fi future people have been dreaming about, one that inspired an entire generation of dreamers and innovators. People are again imagining a future like we saw in the landmark film '2001: A Space Odyssey', where private spacecraft offered frequent flights into space. This is going to be one of the most exciting stories of the 21st century, and we are just at the beginning of that story."

Big Brush Fire at KSC (Update)
Brush Fire at KSC Near Media Center, SpaceRef
A small brush fire started shortly before 1:00 pm near the Kennedy Space Center media center. At present KSC fire personnel have responded to the fire and a NASA PAO representative has said they expect to have it under control soon. As you can see by these pictures fire personnel have been stationed near the media center. Inside the media center a Lego demo was ongoing and activity is normal.
Keith's note: According to Marc Boucher this brush fire is clearly spreading and flames are visible from locations near the press site. Here's a new photo taken moments ago from the press site.
SpaceflightNow is streaming live video of the fire.
Not an everyday site at the KSC countdown clock.
Smoke billows past just east of the media center.
White House Logo Use Update
White House Threatens Science Blog Over Use of Logo, Electronic Frontier Foundation
"When Keith Cowing made an innocuous post about a meeting of the President's Council of Advisors on Science and Technology on his long-running science policy blog, Space Ref, he didn't imagine that it would trigger a phone call from the White House. But that is exactly what happened, and the White House was not calling to congratulate him on his excellent science policy coverage. Cowing's offense? Including an image of the seal of the Executive Office of the President of the United States in his blog post. According to Cowing, White House staffer Rick Weiss objected to the seal's placement in proximity to an ad, which White House lawyers worried might be construed as an endorsement of the product."
White House bullies science blog over use of logo, TG Daily
"Cowing's use of a government logo isn't deceptive either. The seal is clearly used in relation with the news article and the ad is no closer on his blog than ads are on news websites and in most newspapers and magazines. In actuality, the seal of the Executive Office of the President of the United States is widely used all over the internet. Sometimes it's even used in close proximity to advertising. The threatening calls from the White House seem more like attempts to curb free speech than anything else. It's quite pathetic actually. It raises the question; doesn't the White House have better things to do than bully bloggers who are involved in free speech? Sadly we live in a world where the White House needs more training on how the First Amendment works."
White House Threatens Blog For Accurately Using White House Logo, Techdirt
"The latest involves the White House, who apparently got upset that blogger Keith Cowing (of SpaceRef.com -- a blog about science/space policy) included the White House logo in his post about a meeting of the President's Council of Advisors on Science and Technology. In response, the White House actually called Cowing and demanded he take down the logo."
Weißes Haus: Anruf nach Verwendung ihres Logos, gulli
"Blogger Keith Cowing staunte nicht schlecht, als er vor ein paar Tagen einen Mitarbeiter des Weißen Hauses am Telefon hatte. Der rief ihn nicht etwa an, um ihm für seinen Eintrag zu gratulieren. Er wurde vielmehr aufgefordert, das offizielle Siegel des Weißen Hauses aus seinem Blog zu entfernen. Die verwendete Grafik sei einer Anzeige gefährlich nahe, so die Erklärung der Rechtsabteilung."
Endeavour Is Good to Go
It's a Unanimous "Go" for Endeavour
"The Space Shuttle Program Mission Management Team voted unanimously to proceed toward Endeavour's scheduled liftoff at 3:47 p.m. EDT Friday. Mike Moses, chair of the Prelaunch Mission Management team, reported that it was a very short meeting and everything is in great shape and ready to go."

Shuttles and Museums: Thinking Outside The Box
Making Do With a Plywood Spaceship, New York Times
"Q. What was your response when NASA announced its decision?
A. A shuttle would have been our first choice. I won't pretend we're not disappointed, but we're moving forward.
Q. What are the plans for the Space Gallery?
A. We will have a full-size mockup of the space shuttle -- a full fuselage shuttle trainer. It looks exactly like the shuttle except that it doesn't have wings. One advantage is that because it is not a priceless artifact like the shuttle, we'll be able to use it for educational purposes. Some people, but not everyone, will be able to go inside. They won't be able to do that with the shuttles. The trainer is about the size of a 747. The tail is 56 feet high. From the outside it will look exactly like the shuttle except for the wings."
Keith's note: I predict that the Seattle folks will create an experience for visitors that will eclipse all others - even those that use real orbiters. Imagination can often trump reality. Seattle has that. Houston: take note.
Six Reasons Why Physics Is Critical To Contract Machining
Great question came in the other day.
