Whose Vacuum Chamber is Bigger: JSC or GRC? (Update)

NASA Plum Brook vacuum chamber in Sandusky is the largest in the world, despite what NASA folks in Texas claim, Cleveland.com

"The vacuum chamber at Plum Brook, called the Space Power Facility, measures 863,000 cubic feet. To get an idea of its vastness, check out the opening minutes of "The Avengers" movie, filmed inside the chamber. The one at Johnson, called Chamber A, is 400,000 cubic feet."

NASA Invites Media Inside World's Largest Vacuum Chamber, JSC

"The world's largest thermal-vacuum chamber will be open to news media at NASA's Johnson Space Center in Houston on Thursday, April 4."

Keith's 9 April update: The JSC Vs GRC competition claiming that they both host "the world's largest thermal vacuum chamber" continues despite the fact that GRC's has a volume twice the size of JSC's. According to This week at NASA, 8 April 2013 at 5:20 into the video JSC has "...the world's largets thermal vacuum chamber ..." I guess facts are irrelevant to JSC PAO. Odd that this video still makes this claim when NASA PAO quietly modified its original release to say something else (see below).

NASA audit says test facilities in Cleveland, Sandusky may be expendable, Cleveland.com

"K-Site Cryogenic Propellant Tank Research Facility (vacuum chamber)
Location: NASA Plum Brook
Year built: 1958
Last year used: 2004
Yearly operating and maintenance cost: $0 (inactive)
Reason for declining use: Poor condition
Future plans: Demolish by 2014"

Keith's 1 April note: Whoa ... NASA has done some quiet updating to a media advisory without bothering to send a revised press release to the media. If you go to the archived version of this release at NASA.gov it is now titled "NASA Invites Media Inside One of the World's Largest Vacuum Chambers" it opens with "HOUSTON -- One of the two largest vacuum chambers in the world will be open to news media at NASA's Johnson Space Center in Houston on Thursday, April 4.". Yet the original version that I posted on SpaceRef (I have archived the version of what JSC sent out) - was different i.e. "NASA Invites Media Inside World's Largest Vacuum Chamber 03/21/2013 12:00 AM EDT The world's largest thermal-vacuum chamber will be open to news media at NASA's Johnson Space Center in Houston on Thursday, April 4."

When they first issued this release, it was fine to brag about big stuff at JSC. But when it became clear to them that they were wrong, well, why mention GRC eh? Its just another NASA center. JSC made a mistake and now they are afraid to even admit it - and quietly change the original and hope no one will notice. How pathetic.
