NASA's plans for 2003 were abruptly changed February 1 with the sudden and tragic loss of the Space Shuttle Columbia and the brave crew of STS-107.

Even while mourning the loss of our courageous astronauts, NASA's civil service and contract workforce began the challenging task of finding the problem, fixing the problem, and preparing to return Space Shuttles to safe flight. With the Columbia Accident Investigation Board's report and NASA's Implementation Plan for Space Shuttle Return to Flight and Beyond as guides, the agency is striving to return to safe and efficient human space exploration.

The tragic Columbia accident did not disrupt NASA's quest for discovery. In the pursuit of our mission goals, we will continue to expand the International Space Station's remarkable capabilities, send robotic spacecraft to explore fascinating places throughout the solar system, use telescopes to find Earthlike planets orbiting nearby stars, and use satellites to help us better understand Earth's dynamic climate.

"The NASA family faced many tough challenges in 2003," said NASA Administrator Sean O'Keefe. "The loss of Columbia's crew, and two pilots involved in debris recovery efforts in East Texas, deeply affected each of us. I can't express how proud and grateful I am for the efforts of NASA employees, our contractors, and the thousands of others involved in helping us recover from the accident. It has been even more impressive to witness the efforts of all involved, as we move forward toward return to flight," he said.

NASA is energetically approaching return to Shuttle flight operations, completion of the International Space Station and scientific exploration in a safe, milestone driven manner. NASA continues to strive to understand and protect the Earth; explore the universe; search for life; and inspire the next generation of explorers, as only NASA can. We are facing the most critical and exciting time in NASA's 45 year history. The technical and cultural challenges, and changes the agency makes will guide the organization for the next decade. We will succeed and continue to lead the efforts to explore the universe through space-based research, " Administrator O'Keefe concluded.

Huge effort for Columbia debris recovery

The first rover, Spirit, is preparing to land on the mysterious and dangerous Martian surface on Jan. 3, 2004. Its twin, Opportunity, is schedule to land January 24. The Stardust spacecraft is on track for its rendezvous with comet Wild 2. Stardust will gather comet dust and debris and bring it back to Earth in January 2006.

Best 'baby picture of the universe'
In one of the most important scientific discoveries of recent years, NASA released the best "baby picture" of the universe ever taken. The image contains stunning detail of the universe just after the big bang. Scientists using NASA's Wilkinson Microwave Anisotropy Probe, captured the afterglow of the big bang, called the cosmic microwave background. One of the biggest surprises revealed is the first generation of stars to shine in the universe ignited only 200 million years after the big bang, much earlier than many scientists expected.

NASA helps celebrate 100 years of powered flight
NASA exhibits toured American cities creating an awareness of the 100th anniversary of the Wright Brothers historic flight on Dec. 17, 1903 near Kitty Hawk, N.C. Exhibits traced the history of powered flight, and the evolution of aircraft.

Voyager approaching solar system final frontier
NASA's Voyager 1 spacecraft is about to make history again. It is the first spacecraft to enter the solar system's final frontier, a wide boundary region, where wind from the sun blows hot against thin gas between the stars: interstellar space.

Valuable science data gained during Columbia's final mission
Approximately 30 percent of the data collected during Columbia's last mission was recovered and have already yielded exciting and novel findings. While nothing can compensate for the tragic loss of the crew, the devotion of the teams of investigators, students, and researchers to obtain the maximum amount of knowledge from their experiments serves as an enduring tribute to the research and crew of STS-107.

Black holes reveal surprises
NASA's Chandra X-ray Observatory detected sound waves, for the first time, from a super-massive black hole. The note was the deepest ever detected from an object in the universe. Using satellite and other observatories, scientists viewing the scene of a gamma ray burst, just after the explosion, witnessed the death of a gigantic star and the birth of something monstrous in its place, quite possibly a brand-new, spinning black hole. The burst was the most detailed ever observed.

Mars Odyssey points to cause of gullies
Images from the visible light camera on NASA's Mars Odyssey spacecraft, combined with images from the Mars Global Surveyor, suggest melting snow is the likely cause of the numerous eroded Martian gullies. The findings suggest the gullies may have been created by trickling water from melting snow packs, not underground springs or pressurized flows.

Educator Astronaut Program debuts
NASA created a unique program for teachers to join the agency's Educator Astronaut (EA) Program. EAs will serve as Mission Specialists on Space Shuttle and Space Station missions. They will also provide a direct connection between educators and students. The first EA class will be announced in February 2004.

Hubble continues amazing career
NASA's Hubble Space Telescope measured the mass of the oldest known planet and closed a decade of speculation about the nature of this ancient world, which is 2.5 times the mass of Jupiter. Hubble snapped a stunning portrait of Mars within minutes of the planet's closest approach to Earth in nearly 60,000 years. The sharp, natural-color view revealed several prominent features, including the largest volcano in the solar system, a system of canyons and the southern polar ice cap. Hubble is seeing the conclusion of the cosmic epoch called the "Dark Ages," which occurred about a billion years after the big bang. Scientists can see back to when stars in young galaxies began to shine in significant numbers, concluding the cosmic "dark ages" about 13 billion years ago.
