The International Space Station's crew and Atlantis' astronauts form a circle in zero-gravity for a portrait: Atlantis' crew consists of NASA astronauts Chris Ferguson, Doug Hurley, Sandy Magnus and Rex Walheim; the space station's crew members are Japanese astronaut Satoshi Furukawa, NASA astronauts Ron Garan and Mike Fossum, and Russian cosmonauts Andrey Borisenko, Alexander Samokutyaev and Sergei Volkov. The U.S. flag pictured was flown on the first space shuttle mission and is being presented to the space station crew.

The astronauts making NASA's last shuttle flight are almost done packing up their gigantic suitcase for the ride home.

The 10 space travelers spent Sunday putting some final items in Raffaello, the Italian-made cargo canister that's the size of a bus.

"Keep going, you are almost done," encouraged Mission Control.

The compartment will be moved from the International Space Station back onto space shuttle Atlantis early Monday. It carried up tons of food, supplies and other household goods. And it will return with dozens of bundles of trash and discarded equipment.

Atlantis will undock from the space station Tuesday, after a visit of more than a week, and aim for a Thursday landing back in Florida to end 30 years of shuttle flight.

The four shuttle astronauts took some time off Sunday to relax before heading home.

In a departure from last week's string of celebrity greetings, Sunday's special message to the crew aboard Atlantis came from workers at NASA's Stennis Space Center near New Orleans. That's where the shuttle main engines were tested over the decades.

"It's time to fire up your engines — laissez les bons temps rouler!" the Stennis crowd shouted.

The wake-up music was Kool and the Gang's "Celebration," chosen by the shuttle crew before the flight.

Astronaut Sandra Magnus said the crew picked the song "to dedicate to the whole shuttle work force in celebration of everything that you've accomplished over the years."

NASA is retiring its three space shuttles, sending them to museums, so it can work on sending astronauts beyond low-Earth orbit. The goals set forth by the Obama administration: an asteroid by 2025 and Mars by the mid-2030s.

  1. Atlantis rising

    The space shuttle Atlantis makes its maiden voyage on Oct. 3, 1985, for the Defense Department's STS-51-J mission. At 176,413 pounds, Atlantis is nearly 3.5 tons lighter than Columbia, which was the heaviest shuttle. Atlantis is the lightest shuttle of the remaining fleet, weighing 3 pounds less than the shuttle Endeavour (with the three main engines). Atlantis is also the last space shuttle to be retired.

    Other statistics:
    Length: 122.17 feet
    Height: 56.58 feet
    Wingspan: 78.06 feet (Phil Sandlin / AP) Back to slideshow navigation
  2. First of its kind

    NASA's Magellan spacecraft is deployed from Atlantis' cargo bay in 1989 during the STS-30 mission. The Venus orbiter was the first interplanetary probe launched from a space shuttle. Later that year, Atlantis launched the Galileo probe to Jupiter. (NASA) Back to slideshow navigation
  3. Mission to Mir

    NASA and the Russian space agency kicked off a new era in international space cooperation during the STS-71 mission in June 1995, when Atlantis docked with Russia's Mir space station for the first time. This historic photo of the linked spacecraft was taken from a Russian Soyuz capsule during a fly-around. (NASA) Back to slideshow navigation
  4. Here's looking at you

    The space shuttle Atlantis begins the slow journey to Launch Pad 39A from the Vehicle Assembly Building at NASA's Kennedy Space Center in preparation for the launch of STS-79 in September 1996. This dramatic view, looking directly down onto the shuttle stack, was taken from the roof of the 525-foot-tall VAB. (NASA) Back to slideshow navigation
  5. Science in orbit

    Astronaut Shannon Lucid floats through the tunnel that connects Spacelab to Atlantis' cabin on Sept. 24, 1996. The Spacelab module rode in the shuttle's cargo bay and provided more space for scientific experiments. During this STS-79 mission, Atlantis linked up with Russia's Mir space station and brought Lucid back to Earth. (NASA) Back to slideshow navigation
  6. Lighting up the night

    Atlantis streaks into the early morning sky from NASA's Kennedy Space Center on May 15, 1997, as seen in this long-exposure photo taken from Veterans Memorial Park in Titusville, Fla. Atlantis' 10-day STS-84 mission featured a docking with Russia's Mir space station and a crew transfer. Atlantis docked with Mir seven times before the space station was deorbited in 2001.

  7. Good as new

    The space shuttle Atlantis went back to its assembly plant in Palmdale, Calif., for 10 months of refurbishment and upgrades in 1997-1998. This aerial photo shows Atlantis taking a piggyback ride back to Kennedy Space Center in Florida atop a modified Boeing 747 jet on Sept. 1, 1998. (NASA) Back to slideshow navigation
  8. Checking it out

    Atlantis' upgraded cockpit gets a once-over in 1999 from engineers and executives, including Roy Bridges, Kennedy Space Center's director (seated at bottom left), as well as Laural Patrick, Joann Morgan and George Selina. The upgrades made Atlantis the most modern orbiter in the shuttle fleet, with a control system as advanced as those found on commercial jet airliners and military aircraft.

    Atlantis' astronauts leave their quarters at Kennedy Space Center and board the "Astrovan" for the ride out to Launch Pad 39B on Sept. 8, 2006, while gun-toting guards keep watch. A faulty fuel gauge grounded the shuttle for an extra day, but on Sept. 9 the shuttle lifted off on its STS-115 mission to the International Space Station. It marked Atlantis' first launch since 2002. (Jeff Haynes / AFP - Getty Images) Back to slideshow navigation

  23. Last rendezvous

    The space shuttle Atlantis docks with the International Space Station for the last time on July 10, 2011. The shuttle delivered more than four tons of food, clothes and other supplies to keep the space station going in the post-shuttle era. NASA figures that this shipment will help keep the space station provisioned at least through the end of 2012. (NASA TV) Back to slideshow navigation
  24. Flight into history

    This poster pays tribute to the shuttle Atlantis' quarter-century of spaceflight: Graphic elements include the International Space Station and Russia's Mir space station, the Hubble Space Telescope (which Atlantis visited during the last servicing mission) and Venus and Jupiter (which were the destinations for probes launched from Atlantis). Threaded through the design are the mission patches for each of Atlantis' flights. A copy of this tribute poster hangs in Firing Room 4 of the Launch Control Center at NASA's Kennedy Space Center in Florida. (Amy Lombardo / NASA) Back to slideshow navigation
