Astronauts uncover long line of nicks on shuttle

Tuesday, May 12th, 2009

CAPE CANAVERAL, Fla. — The Atlantis astronauts have uncovered a long stretch of nicks on their space shuttle, the result of launch debris.

They were inspecting their ship Tuesday for signs of launch damage when they came across the nicks. Mission Control informed the crew that it’s a 21-inch stretch of nicks over four to five thermal tiles on the right side of Atlantis. The damage is where the right wing joins the fuselage.

Mission Control says it could be related to debris that came off the fuel tank almost two minutes after liftoff.

NASA says the damage does not appear to be serious, but more analysis is needed.

Atlantis blasted off Monday on a risky repair mission to the Hubble Space Telescope. Endeavour is on standby in case a rescue is needed.

Cold front could thwart Friday’s shuttle launch

Wednesday, November 12th, 2008

CAPE CANAVERAL, Fla. – An approaching cold front could thwart NASA’s plans to launch space shuttle Endeavour on Friday on a flight to the international space station.

But the seven astronauts arrived Tuesday ahead of the countdown start and hopeful for an on-time liftoff.

“This mission is all about home improvement, home improvement both inside and outside,” shuttle commander Christopher Ferguson said after flying in Houston with his crew.

During the 15-day mission, the astronauts will deliver a new bathroom, kitchenette, two bedrooms and exercise machine, as well as a water recycling system — and a new resident for the space station. A new astronaut will replace one of the three space station residents.

The plan is to expand the living quarters of the space station so the crew can be doubled to six by next June.

“On the inside of the space station, the walls are largely up,” Ferguson said. “… Well, it’s moving day. It’s time to fill them up.”

Ferguson also noted the never-before-attempted repairs that are planned for outside the space station. Three of the crew will take turns going outside to clean and lubricate a clogged joint that is preventing one set of solar wings from turning automatically toward the sun, and they’ll replace its bearings.

Six hours after the astronauts’ arrival, the countdown clocks began ticking late Tuesday night.

This will be NASA’s first shuttle launch since the end of May.

“We haven’t had a launch for a while, so we’re really excited to be back in the saddle again,” said test director Jeff Spaulding.

The threatening cold front was moving across the central part of the nation Tuesday and was expected to bring rain and thick clouds to the launch site by week’s end.

Shuttle weather officer Kathy Winters said there was a 60 percent chance of acceptable conditions at the 7:55 p.m. Friday liftoff time and only a 40 percent chance on Saturday.

“The timing of the front will be critical,” she said.

NASA has a shuttle launch window until Nov. 25.

Shuttle mission complete; astronauts ready to head home

Tuesday, June 10th, 2008

CAPE CANAVERAL, Fla. – Astronaut Garrett Reisman is in hot water with his wife.

When asked Monday what he was looking forward to most about returning to Earth this weekend after three months in space, he summed it up in two words: Simone Francis.

“She was furious with me for embarrassing her like that,” Reisman said with a laugh Tuesday. “But the truth is that when I look out the window at the planet and I look down at all the people down there, I’m usually just thinking about just one of all those billions of people. And that’s definitely what I’m looking forward to seeing the most.”

A few minutes later, a TV interviewer told Reisman it was “the most romantic answer I think I’ve ever heard about what you miss most on Earth.”

Reisman was going to be on the shuttle side of the hatches later Tuesday, following their closing at the international space station. He moved into the space station in March and was replaced by astronaut Gregory Chamitoff, who flew up on Discovery for a six-month stay.

“This is a hand-over between one Jewish astronaut and another, so we’re pretty excited about that,” Chamitoff said.

Chamitoff, 45, an aeronautics researcher, took up some bagels to share with Reisman — they were made by Chamitoff’s family in Montreal — as well as a few mezuzahs that he’s flying for friends. He said he can’t install the mezuzahs, religious objects attached to the entrances of Jewish homes, because “we can’t decorate the space station as we like.”

Reisman, 40, a mechanical engineer, spent the past week showing Chamitoff the ropes and gave him his phone number in case he needed to ask something. “He’s probably going to change his number,” Chamitoff said, laughing.

Discovery is scheduled to pull away from the space station on Wednesday, ending a nine-day visit that was highlighted by the installation of a brand new Japanese lab.

The shuttle is due back on Earth on Saturday.

Shuttle Endeavour blasts off to begin longest space station mission ever

Tuesday, March 11th, 2008

CAPE CANAVERAL, Fla. – Shuttle Endeavour and a crew of seven blasted into orbit Tuesday on what was to be the longest space station mission ever, a 16-day voyage to build a gangly robot and add a new room that will serve as a closet for a future lab.

The space shuttle roared from its seaside pad at 11:28 p.m. Tucson time, lighting up the sky for miles around as it took off on a multinational flight involving Canada and Japan.

It was a rare treat: The last time NASA launched a shuttle at nighttime was in 2006. Only about a quarter of shuttle flights have begun in darkness.

“Good luck and Godspeed, and we’ll see you back here in 16 days,” launch director Mike Leinbach radioed to the astronauts right before liftoff.

“Banzai,” replied Endeavour’s commander, Dominic Gorie, using a Japanese exclamation of joy. “God truly has blessed us with a beautiful night here, Mike, to launch, so let’s light ‘em up and give ‘em a show.”

They did. The shuttle took flight with a flash of light, giving a peach-yellow glow to the low clouds just offshore before disappearing into the darkness.

Gorie and his crew face a daunting job once they reach the international space station late Wednesday night. The astronauts will perform five spacewalks, the most ever planned during a shuttle visit.

The launching site was jammed with Canadians and Japanese representing two of the major partners in the international space station. The Canadian Space Agency supplied Dextre, the two-armed robot that was hitching a ride aboard Endeavour, while the Japanese Space Agency sent up the first part of its massive Kibo lab, a storage compartment for experiments, tools and spare parts.

Also on hand for the liftoff was a 19-member congressional delegation led by Rep. Nick Lampson, D-Texas, whose district includes Johnson Space Center in Houston. He is pushing for increased NASA funding.

For the first time since space station construction began nearly 10 years ago, all five major partners were about to own a piece of the orbiting real estate. The launch of the first section of Kibo, or Hope, finally propelled Japan into the space station action.

“With this flight I believe that we finally became a real partner of the (space station) project, not just one of the members on the list, after 20 some years of effort in the project,” said Keiji Tachikawa, head of the Japanese Space agency.

Work on the space station project began in the mid-1980s, with preliminary design work for Kibo (pronounced KEE’-boh) starting in 1990. Space station construction, however, was stalled over the years for various reasons, most recently the 2003 Columbia tragedy.

The main part of the Kibo lab will fly on the next shuttle mission in May, with the final installment, a porch for outdoor experiments, going up next year.

Altogether, the Japanese Space Agency has invested about $6.7 billion in the space station program, including a Kibo control center near Tokyo.

Canada’s $200 million-plus Dextre, meanwhile, is designed to eventually take over some of the more routine outdoor maintenance chores from spacewalking astronauts. Dextre, short for dexterous and pronounced like Dexter, will join the space station’s Canadian-built robot arm, already in orbit for seven years.

In addition to working with their international payloads, Endeavour’s astronauts will try out a caulking gun and high-tech goo on deliberately damaged shuttle thermal tile samples. The test — part of NASA’s ongoing post-Columbia safety effort — should have been performed last year, but was put off because of emergency space station repairs.

Astronaut Garrett Reisman will stay behind on the space station until June, swapping places with a Frenchman who accompanied Europe’s Columbus lab into orbit in February.

A Japanese astronaut is also part of Endeavour’s all-male crew.

Endeavour’s countdown was the smoothest in years, officials said. Shortly after liftoff, however, the astronauts had to deal with a couple of problems that ended up being minor. They got alert messages for some of their ship’s steering thrusters, but it turned out to be a bad electronics card. Then the primary cooling system failed, and they had to switch to the backup.

A cursory look at the initial launch images — fewer than usual because of the nighttime launch — showed only one significant loss of debris from the external fuel tank 83 seconds into the flight. But it appeared to miss the right wing.

In any event, Endeavour will be checked thoroughly in orbit for any potential damage, standard procedure ever since the loss of Columbia because of a foam strike.

“This is just a wonderful beginning to what’s going to be a long and challenging mission for us,” said LeRoy Cain, a shuttle manager who gave the final “go” for launch. “But we’re really looking forward to it and we’re ready to go, ready to get to work on orbit.”

It is the second of six planned shuttle missions this year, all but one to the space station. NASA faces a 2010 deadline for finishing the station and retiring its shuttles.

Shuttle ready to leave station; astronaut has been there 4 months

Monday, February 18th, 2008

CAPE CANAVERAL, Fla. – The crews of the space shuttle and International Space Station said a teary farewell, then sealed the hatches between them Sunday after more than a week of working tirelessly together to build a bigger and better scientific outpost in orbit.

Atlantis was scheduled to undock early Monday, its load considerably lighter than when it arrived Feb. 9 with Europe’s Columbus space laboratory.

Astronaut Daniel Tani was especially emotional as he left the International Space Station, his home for the past four months.

Before floating into Atlantis for his long-overdue ride home, Tani paid tribute to his mother, Rose, who was killed in a car accident while he was in space – “my inspiration” – and his wife, Jane, who “had the hard work while I was having fun.”

“I can’t wait to get back to her and my two little girls,” he said.

He also saluted his two female commanders, the space station’s Peggy Whitson and Pamela Melroy, who delivered him to the orbiting complex back in October.

“If we were toasting, if we were in Russia, this would be the third toast,” Tani said, “the toast for the women in our lives.”

Just before the seven shuttle crewmen departed, Whitson said: “All right, you guys, it’s been great having you here.” The astronauts hugged one another and wiped away tears.

NASA aims to wrap up Atlantis’ successful 13-day mission with a landing Wednesday.

Backup readied for spacewalk

CAPE CANAVERAL, Fla. – Shuttle Atlantis’ sick German astronaut looked and sounded well Sunday as he helped a crewmate prepare for a spacewalk that should have been his.

In an extremely unusual move, NASA pulled Hans Schlegel off the spacewalk to help install the European lab Columbus at the International Space Station, and delayed the work until Monday, one day later than planned.

Schlegel, 56, a physicist and former paratrooper who has seven children, was fine for Thursday’s liftoff and became ill in orbit, European Space Agency officials said, adding that the condition was neither life-threatening nor contagious.

The hope is that Schlegel will be well enough to take part in Wednesday’s spacewalk, the second of three planned for Atlantis’ space station visit. He was sidelined Saturday, shortly after the shuttle reached the station.

“We’re all keeping our fingers crossed for him to get better soon,” radioed Europe’s Mission Control near Munich, Germany.

NASA refused to give additional details, citing medical privacy. But it’s common knowledge that a majority of astronauts suffer from space motion sickness during their first few days in orbit.

Schlegel huddled Sunday with his replacement, American Stanley Love, and the other spacewalker, American Rex Walheim, as the men got their equipment ready for Monday’s 6 1/2-hour outing.

Love had trained as a backup for the spacewalk and already was assigned to the mission’s third outing.

Spacing out: Once again, NASA ignores whistle-blowers

Astronaut drinking, flight surgeons’ brushoff shows NASA is broken

CAPE CANAVERAL, Fla. – At NASA, once again, the problem is its culture – a habit of dismissing the concerns of knowledgeable underlings.

Four years ago, it involved higher-ups ignoring engineers who feared possible catastrophic damage to the shuttle Columbia. The engineers were right.

This time, it’s NASA doctors and even astronauts getting the brushoff when voicing worries that some astronauts have had too much alcohol before flying.

“I think things have changed, but some things remain the same,” said Douglas Osheroff, a Nobel Prize-winning physicist who investigated the Columbia disaster in 2003.

An independent health panel disclosed Friday that, at least twice, astronauts were cleared to fly despite warnings from flight surgeons and other astronauts about their heavy drinking.

One intoxicated astronaut flew into orbit on a Russian spacecraft; the other ended up with a shuttle launch delay for mechanical reasons but later tried to take off in a training jet while still under the influence.

In both cases, the doctors and other astronauts were ignored by higher-ranking officials. Flight surgeons feel so disregarded, in general, that they told the panel they are demoralized and less likely to report concerns of impaired performance.

All NASA’s leadership wants, several senior flight surgeons told the panel, is to hear that all medical systems are “go” for space flight operations. They do not want to hear doctors’ doubts about an astronauts’ fitness for duty or behavioral problems, the panel was told.

That was the same perception low-level engineers had during Columbia’s final flight: Their bosses only wanted to hear positive news about the fuel-tank insulating foam that broke off and turned into deadly shrapnel that punctured Columbia’s wing. Seven astronauts died.

“NASA has had a history of ignoring indications that something is wrong, and even though the odds were with NASA, they have lost,” Osheroff said, referring to recurring foam problems before Columbia’s doomed mission.

It always seems to come down to schedule pressure, which contributed in large part to Columbia’s demise, Osheroff noted.

“I think part of it is still this pressure to launch, and launch on time,” he said. “I don’t know what it costs NASA to delay a launch. But there are two costs. One is a political cost and the other is an economic cost.”

Besides tales of drunken astronauts, the health panel heard anecdotes about other risky behavior – unspecified in the report – that was well known to their colleagues, who were too afraid to speak up for fear of ostracism.

With no formal code of astronaut conduct in place and no official, written ban on alcohol within 12 hours of a space launch – two things that are quickly changing – poor behavior was simply overlooked.

That won’t be the case for NASA’s next shuttle launch, set for Aug. 7. The commander, Scott Kelly, and the crew’s lead flight surgeon have already been notified of the space agency’s expectations for their behavior on launch day. They’ve also been urged to bring up any safety concerns.

To further break down any communication barriers, NASA plans an anonymous survey of its astronauts and flight surgeons.

“We want to make sure that there is an open culture here and people are empowered to raise any safety-related concerns,” said Shana Dale, NASA’s deputy administrator.

As a sign of successful culture shift, NASA officials point to the flight readiness review conducted before every shuttle launch, where dissent is encouraged and anyone with a safety concern can speak up. That wasn’t the way it always was – the Columbia accident forced changes.

“It’s troubling to realize that there are still folks who feel there is a problem” communicating concerns, said astronaut Ellen Ochoa, director of flight crew operations.

As for overindulging in liquor, Osheroff finds it mind-boggling that NASA could have cleared intoxicated astronauts for flight.

“Launch and re-entry are the two times when the astronauts have to really be sharp because that is when most of the danger is,” he said. “So the idea of being drunk when you’re going up, you might as well go up in a casket.”

NASA is up against almost 50 years of tradition when it comes to astronaut high jinks. Ever since the seven original Mercury fliers were selected in 1959, the stereotype has been a cocky but competent pilot who works and lives hard – a flyboy.

The panel assessing astronaut health was appointed this year after the risky actions of another astronaut, Lisa Nowak, who is accused of a pepper-spray attack on the girlfriend of a fellow astronaut. Nowak has pleaded not guilty to charges of attempted kidnapping, battery and burglary with assault.

The panel – of eight medical experts with government ties – acknowledged that many of the cultural issues have been around since the beginning of the astronaut program and will be hard to fix.

“Cultural changes such as these will and must disrupt the status quo,” the panel concluded. “While cultural changes are the most difficult to achieve, they are also the most significant and pose the highest risk of human failure if not adequately addressed.”

Osheroff notes that in the corporate world, complete culture change often comes only after enough new people are hired and the old guard is gone.

At NASA, that could take a while.
