It is time to end the shuttles. They cannot seem to get off the ground without damage to the vehicle. I wonder why this seems to be such an issue over the last few years and not so much in the previous decades. Good thing a spare is ready to go. Just a scratch boys pretty sure you will make it ????????
It is too bad that they did not think much ahead and it will be at least five years before the Orion class is ready.
Reminds me of my GM car with its broken window motors and electrical malfunctions. No wonder they are going out of business. American engineering at its best.

You hit the nail directly on the head. Why all of the issues now? I understand the increased awareness since the two tragedies, but all-of-a-sudden [ or so it seems ], each mission is thrice as risky as the last.
As regards the new 'fleet', it is long overdue. Look at the technological advancements, in general, since the current fleet was developed, let-alone launched.
My biggest gripe is the fact that the government, in all probabilty, has enough advanced [and covert] technology to make all of this crap unnecessary. Are you seriously trying to tell me that we could put men on the moon in the sixties, yet today we don't have the technology to get them safely off of the ground, put in orbit, and returned to earth?
NASA, today, is nothing more than a joke cover for the hidden technology that the government is in posession of, and that it is unwilling to let the public [ and other world parties ] be aware of. In the meantime, America's astronauts [including CIVILIANS], the one's down-range on the firing line, are at risk to keep the secrets from view.
Disgusting...

Did I miss something? Is this a set up mission? God I hope not but after reading this forum and information that is leaked through various sources I do tend to always question the seemingly circumstantial events that lead to something larger. I hope my gut is wrong on this.
Just imagine this scenario, the shuttle is stranded in space, the only way they can be rescued is by the backup shuttle. Unfortunately there is a technical problem with this one too. The situation is hopeless until an alien spacecraft come to the rescue, bringing the astrnauts to earth. There's your disclosure!

Heat Shield Survey Complete Tue, 12 May 2009 08:51:28 PM GMT Atlantis’ crew completed a planned survey of the shuttle heat shielding today, noting a few dings in tiles that experts will continue to analyze. Flight Director Tony Ceccacci said that upon an initial look, damage found during the inspection appeared to be minor and likely not a concern, but he said experts would analyze it as is normal to be certain the shuttle’s heat shielding is in good shape. The damage included small dings along an area of about 21 inches spanning four of the shuttle’s thermal tiles located on the starboard side of the spacecraft where the wing blends into the forward fuselage.
On their third and final spacewalk on July 12, Sellers and Fossum used a "space-certified" caulking gun and a variety of spatulas and tools to test materials on samples of pre-damaged reinforced carbon-carbon panels. "We're getting some good stuff done here, mate," Sellers told Fossum during the spacewalk.
Two of the crew of seven astronauts participated in practicing with the caulking guns and putty-knives in the open cargo bay for seven hours
Development of repair method
NASA is attempting to develop a method to repair the critical RCC panels. Scientists have developed a pre-ceramic polymer sealant impregnated with silicon carbide that is referred to as Non-Oxide Adhesive eXperimental (NOAX). Damage in the protective outer silicon-carbide coating of the RCC may be repaired with NOAX, which converts to silicon carbide during re-entry. They have also designed a special space caulking gun that astronauts will use to apply a small amount of repair material to the damage site. They will work the material with a putty knife and use it to fill in cracks and holes in the RCC panels. If this procedure should ever be required on an actual shuttle mission, the lives of the crew will depend on the integrity of the repair. So NASA has embarked on an extensive testing program during which it has planned several arc jet tests (re-entry simulation) as well as thermal-vacuum tests prior to certifying the new material for use in an actual flight. Most of these development and verification tests have been performed on the ground, either in a laboratory setting or in vacuum chambers, but astronauts Piers Sellers and Mike Fossum conducted repairs of arc jet samples during a spacewalk on STS-121 in July 2006. All of the arc jet samples repaired during the on-orbit evaluation were tested in the arc jet and successfully completed the entry simulation without
Atlantis continues to close in on the Hubble Space Telescope, heading toward a rendezvous and capture of the observatory at 12:54 p.m. EDT Wednesday. The crew members plan to check out the equipment they will use for the final phase of the rendezvous today while telescope controllers plan to close the aperture door of the instrument in preparation for the shuttle’s arrival.

Does anyone know if they have arrived at the Hubble yet,
and when will the first walk be?
