To see one shorn shuttle is bad enough. Seeing two NASA space shuttles edged together and voluntarily gutted of their spaceflight capability for lack of Federal Government funding in the prime of their lives is beyond sad.

Two of NASA’s trio of space shuttle orbiters – Discovery & Endeavour – switched locations at the Kennedy Space Center (KSC) on August 11, moving them further down the path to eternal retirement and public exhibit at their future homes in museums. That’s far afield from their intended purpose to soar as spaceships of exploration to the High Frontier.

Discovery and Endeavour briefly met in a matchless nose-to-nose configuration for a roadside photo opportunity between the humongous Vehicle Assembly Building (VAB) and the processing hanger – dubbed the Orbiter Processing Facility – where the orbiters are prepared for flight.

Space Shuttle’s Discovery and Endeavour swapped places at KSC so that technicians could resume preparations towards the transition and retirement of shuttle Discovery – the first of NASA’s orbiters to be officially withdrawn from active duty spaceflight service.

First, Discovery was backed out of temporary storage from a high bay inside the VAB. Then Endeavour was towed out of Orbiter Processing Facility-1. Technicians then maneuvered the orbiters to a rendezvous point in between on the ground. Just imagine how grand this vista would have appeared in space.

At last Discovery and Endeavour met for the truly sad nosy encounter of gaping holes where the forward reaction control thrusters once fired to meticulously maneuver the shuttles in orbit. Protective plastic sheeting meant to shield the empty thruster bay from FOD – or Foreign Object Debris – was in tatters and whipping wildly in the wind almost from the moment Discovery emerged from the VAB.

The rear ends of both orbiters looked like the main engines had been sawed off. Both orbiters have been stripped of their trio of mighty space shuttle main engines (SSME’s) and duo of bulbous Orbital Maneuvering System (OMS’s) pods for months of decommissioning work.

Discovery was then pulled into the Orbiter Processing Facility-1 (OPF-1) where the next step is to extract even more of her guts, namely the Auxiliary Power Units (APU’s) and associated systems for “safing” over the coming months. In April 2012, Discovery is scheduled to depart KSC forever and be flown off for permanent public display at the Smithsonian’s National Air and Space Museum Steven F. Udvar-Hazy Center in Virginia.

Endeavour was towed into the VAB for storage until October, when she will be moved into OPF-2 for further work to ready her for public display at the California Science Center in Los Angles sometime next summer.

Atlantis is next on the chopping block. And America retains zero indigenous capability for human spaceflight.

The situation likely won’t change for at least several years until one of the commercial providers launches a human rated “space taxi” to low earth orbit.

CAPE CANAVERAL, Fla. – NASA is experiencing what could be dubbed a “summer of planetary exploration.” With the Juno mission to Jupiter on its way as of Aug. 5, NASA is prepping not one but two more missions – this time to terrestrial bodies – specifically the Moon and Mars.

On Sept. 8 NASA is planning to launch GRAIL (Gravity Recovery And Interior Laboratory). This mirror image spacecraft consists of two elements that will fly in tandem with one another and scan the Moon from its core to its crust. This mission will serve to expand our understanding of the mechanics of how terrestrial bodies are formed. GRAIL will provide the most accurate gravitational map of the Moon to date.

When it comes to upcoming projects that have “celebrity” status – few can compete with the Mars Science Laboratory (MSL) or Curiosity. The six-wheeled rover was part of a media event Friday Aug. 12 that included the “Sky-Crane” jetpack that is hoped will safely deliver the car-sized rover the Martian surface. Also on display was the back half of the rover’s aeroshell which will keep the robot safe as in enters the red planet’s atmosphere.

Numerous engineers were available for interview, one expert on hand to explain the intricacies of how Curiosity works was the Rover Integration Lead on the project, Peter Illsley.

One fascinating aspect of MSL is how the rover will land. As it pops free of the aeroshell, a jet pack will conduct a powered descent to Mars’ surface. From there the rover will be lowered to the ground via wires, making Curiosity look like an alien spider descending from its web. Once the rover makes contact with the ground, the wires will be severed and the “Sky-Crane” will fly off to conduct a controlled crash. Ben Thoma, the mechanical lead on this aspect of the project, described how he felt about what it is like to work on MSL.

MSL is slated to launch this November atop a United Launch Alliance (ULA) Atlas V 541 rocket. If everything goes according to plan the rover will begin exploring Mars’ Gale Crater for a period of approximately two years. In every way Curiosity is an upgraded, super-charged version of the rovers that have preceded her. The Pathfinder rover tested out many of the concepts that led to the Mars Exploration Rovers Spirit and Opportunity and now MSL has incorporated lessons learned to take more robust scientific explorations of the Martian surface.

[/caption]

NASA’s GRAIL twins – dubbed GRAIL-A & GRAIL-B – are ready to embark on America’s next science expedition to the moon in less than 1 month’s time from Cape Canaveral Air Force Station, Fla.

The twin Gravity Recovery and Interior Laboratory (GRAIL) spacecraft have been exhaustively tested, fueled for flight and mounted side-by-side on a specially designed payload adapter inside the controlled environment of a clean room at the Astrotech Space Operations facility in nearby Titusville, Fla.

The next processing step is to encapsulate the lunar probes inside their protective payload fairing. The duo are set to be shipped from Astrotech to their Cape Canaveral launch pad next week on Aug. 16, where they will be mated to an already assembled Delta II booster.

Liftoff of the GRAIL twins is slated for Sept. 8 at 8:37 a.m. EDT by a Delta II Heavy rocket from Launch Complex 17 at Cape Canaveral for a nearly four month voyage to the moon.

After entering lunar orbit, the two GRAIL spacecraft will fly in a tandam formation just 50 kilometers above the lunar surface with an average separation of 200 km during the 90 day science phase.

GRAIL’s mission goal is to map the moon’s gravity field to high precision and thereby deduce the structure of the lunar interior from crust to core. This will also lead to a better understanding of the composition of the moon’s interior, according to Sami Asmar, GRAIL co-investigator from NASA’s Jet Propulsion Laboratory in Pasasdena, Calif., during an interview inside the Astrotech clean room at a photo opportunity for the media. A gravity experiment is also aboard the just launched Jupiter bound Juno spacecraft.

In Their Own Words: Experts Talk Juno

Several scientists and experts discussed the Juno mission to Jupiter with Universe Today. Photo Credit: Alan Walters/awaltersphoto.com

CAPE CANAVERAL Fla. – Many experts took time out of their hectic schedules to talk with Universe Today in the day leading up to the launch of the Juno spacecraft. Some even took the time to talk to us just minutes before the probe was scheduled to be launched on its mission. Check out what they had to say below:

Juno Project Scientist Steve Levin was at Kennedy Space Center to watch the Juno probe begin its five-year journey to Jupiter. He took a few minutes of his time to talk about what his expectations are for this mission.

Levin has been with JPL since 1990, one of the previous projects he worked on is the Planck mission which launched in 2009.

Levin believes that Juno could fundamentally change the way we view Jupiter. He was one of many VIPs that descended on Kennedy Space Center to watch as Juno thundered to orbit atop at Atlas V rocket.

Sami Asmar is part of the science team that is working on the Juno project. He was at the rollout of the Atlas rocket to the pad. Here is what he had to say about the mission (note the Atlas rocket moving out behind him).

Bill Nye the Science Guy was a very busy man while at Kennedy Space Center. He still took the time to chat with Universe Today about his views on this mission. Unfortunately, with little time to spare, we had to conduct the interview within minutes of the first launch attempt. A good chunk of Nye’s interview – was drowned out by the lead up to the countdown!

The usual launch of an Atlas consists of the launch team coming in, pushing a button and going home – the launch vehicle is that reliable. This day, things occurred quite differently. A technical issue coupled with a wayward boat that had drifted too close to the launch pad saw the launch time slip from 11:34 a.m. EDT to 12:25 p.m. When the rocket did take off however it was a spectacular sight to behold, faster than other iterations of the Atlas, it roared off the pad, sending Juno on its way to Jupiter.

SpaceX: Mars Is Our Future

Could an image similar to this be in our near future? If Elon Musk has his way - the answer is yes. Falcon 9 Image Courtesy of SpaceX - Mars Image Courtesy of NASA

[/caption]Elon Musk is not one to rest on prior accomplishments; he likes to continue to push forward – his plans for the future of commercial space flight reflect that philosophy. He has stated his plans to begin crewed flights to Mars. Musk thinks that humans can set foot on the red planet within the next 10 to 20 years. He stated that the rationale behind mankind becoming a multi-planet species should be obvious to all.

“Ultimately, it is vital that we are on a path to becoming a multi-planet species,” said Musk. “If we don’t then our future isn’t very bright, we’ll simply be hanging out on Earth until some calamity claims us.”

Musk made the announcement of his intent during this month’s meeting of the American Institute of Aeronautics and Astronautics (AIAA) that was held in San Diego, California.

SpaceX would presumably utilize the Falcon Heavy rocket, which is slated to conduct its first launch either at the end of 2012 or the beginning of 2013. Whereas the Falcon 9 features nine engines in its first stage, the Falcon Heavy, being a triple-body design similar of the Delta IV Heavy – would utilize 27 Merlin engines. It is estimated that the Falcon Heavy could send 12 to 15 metric tons to orbit.

The proposed Falcon Heavy is scheduled to launch either some time next year or in the early part of 2013. Image Credit: SpaceX

The spacecraft that would fly any mission to the red planet would theoretically be an offshoot of the vehicle that SpaceX sent to orbit last December, the Dragon. In fact the craft/project has already been dubbed the “Red Dragon.”

NASA currently plans to send astronauts to an asteroid by 2025 and to Mars sometime in the 2030s. If SpaceX is successful, this would be far faster than what the space agency has stated it is capable of accomplishing.

SpaceX has had a number of successes lately. It has successfully launched two of its heavy-lift Falcon 9 rockets, the second of which carried the first of the company’s Dragon spacecraft to orbit. Shortly thereafter the company recovered the vehicle as it bobbed safely in the Pacific Ocean after returning safely to Earth. The feat of sending spacecraft to and from orbit had only been accomplished by nations before this.

The NewSpace firm is working to speed up the timeline of the Commercial Orbital Transportation Services (COTS) contract, worth an estimated $1.6 billion, that the company has with NASA. SpaceX has requested and technically received permission to send the next Dragon spacecraft to the International Space Station (ISS) this December. Originally this flight would have been a flyby of the orbiting laboratory to test out several of the spacecraft’s key operating systems. However, one of the ISS partners, Russia, has yet to sign off on this plan however.

The California-based company was also tapped to participate in NASA’s Crew Commercial Development contract (phase 2) – more commonly known as CCDev-02. SpaceX was selected along with Boeing, Sierra Nevada Corporation and Blue Origin. Each firm was awarded a different cash sum to accomplish the proposals that they had set forth.

SpaceX is a company whose scope appears to be rapidly expanding. The announcement at the AIAA by Musk appears to highlight this fact. Mars has long been the destination of choice for many within the space community. Funding and logistics woes have delayed the first manned mission from ever taking place. It remains to be explained how the mission will be flown, will it be unilateral, multi-national or some other mixture? Will private industry take the lead? For his part Musk has thrown down the gauntlet – “Red Dragon” could fly as early as 2018.

Juno Spacecraft Honors Those Who Started It All

Juno begins its five-year journey to the planet Jupiter. On board are several artifacts meant to honor the history of the gas giant. Photo Credit: Alan Walters/awaltersphoto.com

[/caption]
The Juno spacecraft, now safely on its way to the planet Jupiter, is carrying along with it several artifacts in honor of its voyage. Onboard the probe are three, tiny figurines of key players in the mythological and historical background of the gas giant. LEGO figurines of the Roman god Jupiter, his wife Juno and Italian astronomer Galileo Galilei have had their 1.5-inch likenesses added to the voyage.

In Roman mythology Jupiter had cast a veil of clouds over himself to hide his activities. Undeterred, his wife, Juno, peered through the clouds to see Jupiter’s true nature. Hence, her representation onboard the Juno spacecraft – is holding a spyglass. The last member of this odd ‘crew’ is Galileo, the man who made a number of important discoveries regarding the Jovian system.

The inclusion of these three figures is part of a joint effort between NASA and the LEGO group to spark interest in Science, Technology, Engineering and Math or STEM in children. NASA went one step further in acknowledging the accomplishments of the man that made so many discoveries about this massive world. It has included a plaque in honor or Galileo.

During his life, Galileo contributed greatly to mankind’s understanding of the solar system. He discovered in 1610 what have since been dubbed the “Galilean moons” – Io, Europa, Ganymede and Callisto.

This plaque is affixed to the Juno probe bound for Jupiter. It shows an illustration of Galileo as well as an inscription he made regarding the gas giant. Photo Credit: NASA

The plaque was donated by the Italian Space Agency and it measures 2.8 by 2 inches (71 by 51 millimeters). The plaque is manufactured from flight grade aluminum and weighs six grams or about 0.2 ounces. The plaque includes an illustration of the famous astronomer along with an inscription – in his own hand – a passage he made in 1610 concerning his observations of Jupiter. The inscription reads:

“On the 11th it was in this formation — and the star closest to Jupiter was half the size than the other and very close to the other so that during the previous nights all of the three observed stars looked of the same dimension and among them equally afar; so that it is evident that around Jupiter there are three moving stars invisible till this time to everyone.”

Juno successfully lifted off from Cape Canaveral Air Force Station’s Space Launch Complex 41 at 12:25 p.m. EDT on Friday, August 5. It will take the probe about five years to reach Jupiter. Once there it will enter in a polar orbit around the world where it will use its suite of instruments to peer beneath the veil of Jupiter’s clouds to study the planet’s gravity, magnetosphere and whether-or-not the planet has a rocky core.

NASA’s Jet Propulsion Laboratory (JPL) manages the Juno mission for the principal investigator, Scott Bolton, from the Southwest Research Institute in San Antonio. The Juno mission is part of the New Frontiers Program managed at NASA’s Marshall Space Flight Center in Huntsville, Ala. Lockheed Martin Space Systems, Denver, built the Juno spacecraft.

Opportunity Snaps Gorgeous Vistas nearing the Foothills of Giant Endeavour Crater

Martian Vista from Opportunity nearing Endeavour Crater on Sol 2678 - August 2011. Large ejecta blocks from the nearby, small Odyssey crater are visible in the middle, foreground and are Opportunity’s next science target in this photo mosaic taken 2 martian days ago on Sol 2678 (Aug. 6). Opportunity is now less than 400 feet from the foothills of Endeavour Crater and will soon make first landfall at Spirit Point - off to the left. At Endeavour, Opportunity will investigate the oldest minerals deposits she has ever visited from billions of years ago and which may hold clues to environments that were potentially habitable for microbial life.

[/caption]

The epic multi-year trek of NASA’s Opportunity Mars rover to the gigantic Endeavour crater is nearly complete as the plucky rover blazes to within a football fields distance and first landfall at a spot dubbed “Spirit Point” – named in honor of her long lived twin sister “Spirit”. Endeavour beckons because it may hold clues to a time billions and billions of years ago when Mars was warmer and wetter and harbored an environment that was far more conducive to the formation of life beyond Earth.

Opportunity is racing towards the western foothills of Endeavour’s rim and is at long last transmitting stunningly clear images of portions of the crater ridges, revealing gorgeous vistas and intriguing details up the sloped walls. See our new photo mosaics above and below.

As of today, Aug. 8 on Sol 2680 of the mission, the Martian robot is less than 400 feet (150 m) away from Endeavour’s rim at Spirit Point – which lies at the southern tip of one of the ridges known as “Cape York,” on the western side of Endeavour (see map and photo below). The humongous crater is 14 miles (22 km) in diameter.

“Our primary goal is to get onto the older material at Cape York with the phyllosilicate signatures in CRISM,” said Dr. Matt Golembek in an interview with Universe Today. Golembek is a Senior Research Scientist with the Mars Exploration Program at the Jet Propulsion Laboratory (JPL) in Pasadena, Calif.

The phyllosilicate signatures are based on observations by the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) aboard NASA’s Mars Reconnaissance Orbiter (MRO). Phyllosilicates are clay minerals that form in the presence of neutral water and that are more far more hospitable to the possible genesis of life compared to the rocks studied from the more highly acidic aqueous environments examined by the rover thus far.

Opportunity is now transmitting highly detailed and clear images of Endeavour’s rim.

In mid- 2008, Endeavour crater was chosen as the long term destination for Opportunity by the rover science team because it offers access to older geological deposits than any Opportunity has visited and investigated before. These mineral deposits include phyllosilicates.

Opportunity has been sprinting across the plains of Meridiani since departing her last major science stop at Santa Maria crater in March 2011. See our APOD here.

Opportunity is now heading to a spot called “Odyssey crater” on the way to Spirit Point. See JPL route map below.

“In the end of drive Navcams [navigation camera] from Sols 2678-9, large ejecta blocks on the rim of Odyssey crater are clearly visible and that is our next target to see what those blocks are made of,” Golembek told me.

“After that we will travel north into Cape York to better understand the older rocks in Cape York.”

The rover team is being very careful to not over plan the science activities to far in advance and are keeping their options open.

Eventually, Opportunity will scale the ridge and become the 2nd Martian mountain climber. Spirit was the first Earthly emissary to climb to the summit of a mountain on Mars.

“As we explore we will make more specific plans depending on what we see,” Golembek added.

Measurements from orbiting spacecraft like MRO allowed the science team to target Opportunity more precisely toward those ridges of older exposures of rock outcrops and phyllosilicates observed along Endeavour’s western rim.

Given Opportunity’s rapid progress, it’s now almost certain that she will reach the phyllosiliocates before the Curiosity rover is even launched in Nov. 2011.

Endeavour’s crater rim is discontinuous and divided into a series of segmented mountainous ridges – making it all the more beautiful and a bonanza for science. See the new photo mosaics above and below stitched together by Marco Di Lorenzo and Ken Kremer, illustrating Opportunity’s current vistas.

The Spirit rover succumbed to the bitter Martian arctic-like cold weather during her 4th winter on Mars after roving nearly seven years across Gusev crater. In May 2011, NASA declared Spirit’s mission had concluded after no further communications were received.

Opportunity remains healthy, generates sufficient solar power and has traversed an unbelievable 20.6 miles or 33.2 km since landing on Jan. 24, 2004.

Juno Blasts off on Science Trek to Discover Jupiter’s Genesis

JUNO blasts off for Jupiter on Aug. 5 from Cape Canaveral Air Force Station at 12:25 p.m. EDT. Credit: Alan Walters (awaltersphoto.com)

[/caption]

NASA’s solar powered Juno spacecraft blasted off today (Aug.5)from Cape Canaveral today to begin a 2.8 billion kilometer science trek to discover the genesis of Jupiter hidden deep inside the planet’s interior.

Upon arrival at Jupiter in July 2016, JUNO will fire its braking rockets and go into polar orbit and circle the planet 33 times over about one year. The goal is to find out more about the planets origins, interior structure and atmosphere, observe the aurora, map the intense magnetic field and investigate the existence of a solid planetary core.

The spacecraft is healthy and the solar panels successfully deployed.

Check out the photo album of Juno’s launch from the Universe Today team of Alan Walters and Ken Kremer.

“Jupiter is the Rosetta Stone of our solar system,” said Scott Bolton, Juno’s principal investigator from the Southwest Research Institute in San Antonio. “It is by far the oldest planet, contains more material than all the other planets, asteroids and comets combined and carries deep inside it the story of not only the solar system but of us. Juno is going there as our emissary — to interpret what Jupiter has to say.”

[/caption]

The Atlas V rocket that will power NASA’s new Juno science probe to Jupiter was rolled out to the launch pad at Space Launch Complex 41 and now sits poised for blastoff on Friday, Aug. 5 at 15:34 UT (11:34 a.m. EDT) from Cape Canaveral Air Force Station in Florida.

The Atlas V booster rocket was pushed out of its protective hanger, known as the Vertical Integration Facility, and towards Pad 41 this morning starting at 8:01 a.m. and took about 40 minutes to reach its destination.

Weather forecasters continues to call for a 70 percent chance of favorable conditions at launch time, but the approach of Tropical Storm Emily could throw a wrench in NASA’s plans depending on the track following by the storm over the remaining prelaunch period.

According to continuing weather updates, Emily is dissipating.

Managers approved Juno for flight at this morning’s Launch Readiness Review. The 4 ton Juno spacecraft will embark on a five year trek to Jupiter, our solar system’s largest planet and seek to understand the ingredients necessary for planetary formations.

Juno is perched inside a 5 meter diameter payload fairing and mated to the most powerful version of the Atlas V rocket – an Atlas 551 – with 2.4 million pounds of liftoff thrust. The 20 story tall Atlas 551 uses a standard Atlas booster with five solid rocket boosters in the first stage and a single engine Centaur in the second stage.

The launch window extends for 69 minutes.

The Atlas V is built by United Launch Alliance (ULA).

Juno will orbit Jupiter 33 times and search for the existence of a solid planetary core, map Jupiter’s intense magnetic field, measure the amount of water and ammonia in the deep atmosphere, and observe the planet’s auroras. Each orbit lasts 11 days

The spacecraft will provide the first detailed glimpse of Jupiter’s poles via a specially designed camera. The elliptical orbit will allow Juno to avoid most of Jupiter’s harsh radiation regions that can severely damage the spacecraft systems.

Atlantis Final Crew and NASA thank Shuttle Workforce with space flown Tribute Banner

To The Shuttle Workforce – Thanks for 30 Years of Adventures. Commemorative banner flown to the ISS and back by the STS-135 shuttle crew, in thanks for more than 30 years of hard work and dedication by the Space Shuttle workforce preparing the space shuttles for 135 missions to space.

Following the majestic predawn touchdown of Space Shuttle Atlantis at the Kennedy Space Center (KSC) to close out the Space Shuttle Era, the final crew of Atlantis, NASA Administrator Charles Bolden and KSC Director Bob Cabana thanked the Space Shuttle workforce for their dedication and hard work at an employee appreciation event held outside the processing hangers where the orbiters were prepared for the 135 shuttle missions flown by NASA over more than thirty years.

The four person crew of Atlantis on the STS-135 mission flew a special commemorative banner millions of miles to the International Space Station and back in honor of the thousands of workers who processed, launched and landed America’s five space shuttles. They unfurled the banner at the employee event at KSC in tribute to the shuttle workers.

“It’s great to be here in sunny Florida,” said STS 135 Commander Chris Ferguson. “Mike Leinbach [ the Space Shuttle Launch Director] said there was no way he’d let us land in California.”

“We want to express our gratitude on behalf of the astronaut office for everything you have done here at KSC, the safety you have built into the vehicles, the meticulous care that you take of the orbiter. As soon as we got on orbit, I was absolutely amazed that everything in Atlantis works so well. Everything looks beautiful on the inside.”

“I hope you all believe that every time we go, we take a little bit of every one of you with us,” Ferguson emphasized.

Atlantis was parked at the event as a backdrop for photo opportunities with the thousands of shuttle workers in attendance – along with over a hundred journalists including the Universe Today team of Alan Walters and Ken Kremer.

“Like Chris said, our one landing option was getting back to Florida and you all rather than anywhere else. It felt like being home again. Thank you for everything you have all done over the last 30+ years,” said Doug Hurley.

“We treated Atlantis with the utmost respect because we see firsthand how you process this vehicle and it is your baby,” said Rex Waldheim. “It is clean and well cared for. We did that for you because you all did such a great job preparing it for us.”

“You are such a special work force,” added Sandy Magnus. “There is no workforce like the space program workforce anywhere in the world. The pride, care, dedication and passion you take in your work is what makes it possible to have these very challenging missions and to succeed. You have to do everything right all of the time. And you DO. And you make it look easy!! Congratulations!”

The STS-135 crew then unfurled the colorful banner taken to the ISS aboard Atlantis to commemorate NASA’s Space Shuttle Era.

“We took this banner with us to space and this is our way of telling you that you guys rock ! We will present this to Mike Leinbach and Bob Cabana as just a small token of our appreciation for all the work you’ve done for us. Thank you for such a wonderful vehicle,” Ferguson summed up.

The crew then waved good bye to the thousands of shuttle workers, posed with Atlantis one last time and departed with their families for a homecoming celebration at their training base at the Johnson Space Center in Houston, Texas.

Atlantis was then towed a few hundred yards (meters) and came to rest inside the Orbiter Processing Facility to conclude her final spaceflight journey as the last of NASA’s flight worthy Space Shuttle Orbiters. She has began decommissioning activities due to last several months to prepare for her future retirement home at the Kennedy Space Center Visitor Complex (KSCVC) just a few miles (km) away.

Atlantis permanent new abode at KSCVC is set to open in 2013 where she will be genuinely displayed bearing scorch marks from reentry and as though “In Flight” with payload bays doors wide open for the general public to experience reality up close.

For some 1500 shuttle workers, the day’s proceedings were both joyous and bittersweet – as their last full day of employment and last chance to bask in the glow of the triumphant conclusion of the Shuttle Era.
