“Trying to do stellar observations from Earth is like trying to do birdwatching from the bottom of a lake.” James B. Odom, Hubble Program Manager 1983-1990.
The third servicing mission to the Hubble Space Telescope, placed in orbit in 1990, occurred during the STS-103 mission in December 1999. During the mission, originally planned for June 2000 but accelerated by six months following unexpected failures of the telescope’s attitude control gyroscopes, the astronauts restored the facility to full functionality. During their eight-day mission that featured the first space shuttle crew to spend Christmas in space, the seven-member U.S. and European crew rendezvoused with and captured Hubble, and four astronauts in rotating teams of two conducted three lengthy and complex spacewalks to service and upgrade the telescope. They redeployed the telescope with greater capabilities than ever before to continue its mission to help scientists unlock the secrets of the universe.

Astronauts release the Hubble Space Telescope in April 1990 during the STS-31 mission. The discovery after the Hubble Space Telescope’s launch in 1990 that its primary mirror suffered from a flaw called spherical aberration disappointed scientists who could not obtain the sharp images they had expected. But thanks to the Hubble’s built-in feature of on-orbit servicing, NASA devised a plan to correct the telescope’s optics during the first planned repair mission in 1993. A second servicing mission in 1997 upgraded the telescope’s capabilities until the next mission planned for three years later. But after three of the telescope’s six gyroscopes failed in 1997, 1998, and 1999, mission rules dictated a call up mission in case additional gyroscope failures sent Hubble into a safe mode. NASA elected to move up some of the servicing tasks from the third mission, splitting it into missions 3A and 3B, planning to fly 3A in October 1999 on Discovery’s STS-103 mission primarily to replace the failed gyroscopes. Delays to the shuttle fleet resulting from anomalies during the launch of STS-93 in July 1993 slipped STS-103 first into November and ultimately into December. Technical issues with Discovery itself pushed the launch date to mid-December, and raised concerns about having a shuttle in orbit during the Y2K transition. Once the launch had slipped to Dec. 19, mission planners cut the mission from 10 to eight days, deleting one of the four spacewalks, to ensure a return before the end of the calendar year. The servicing mission couldn’t come soon enough, as a fourth gyroscope failed aboard Hubble in mid-November, with Discovery already poised on the launch pad to prepare for STS-103. Controllers placed Hubble in a safe mode until the astronauts arrived.

The mission patch for the Hubble Servicing Mission-3A. To execute the third Hubble Servicing Mission, in July 1998 NASA selected an experienced four-person team to carry out a record-breaking six spacewalks on the flight then planned for June 2000. The spacewalkers included Mission Specialists Steven L. Smith serving as payload commander, John M. Grunsfeld, C. Michael Foale, and European Space Agency (ESA) astronaut Claude Nicollier from Switzerland. The addition in March 1999 of Commander Curtis L. Brown, Pilot Scott J. Kelly, and Mission Specialist ESA astronaut Jean-François A. Clervoy of France rounded out the highly experienced crew with 18 previous spaceflights among them. Brown earned the distinction as only the fifth person to fly in space six times. For Kelly, STS-103 marked his first spaceflight. Smith, Clervoy, and Grunsfeld each had flown two previous missions, Foale four including a long-duration mission aboard Mir, and Nicollier three. Smith participated in three spacewalks during the second Hubble Servicing Mission and Nicollier served as the Remote Manipulator System (RMS) or robotic arm operator during the first.

Discovery arrived back to KSC at the end of the STS-96 mission on June 6, 1999, and workers towed it to the Orbiter Processing Facility the same day to begin readying it for STS-103. The vehicle rolled over to the Vehicle Assembly Building on Nov. 4, where workers mated it with its external tank and twin solid rocket boosters, before rolling the stack out to Launch Pad 39B on Nov. 13.

Two days later, Brown and Kelly maneuvered Discovery to within range of Hubble so Clervoy operating the 50-foot-long RMS could grapple the telescope and berth it into the payload bay.

Smith gives a thumbs up with his image reflected in the Hubble Space Telescope. Smith and Grunsfeld conducted the mission’s first spacewalk on Dec. 22, the flight’s fourth day in space. The duo, aided by Clervoy operating the RMS from inside Discovery, completed two of mission’s highest priority objectives. They replaced the failed gyroscopes, installing three new Rate Sensor Units, each containing two gyroscopes, to return control to the ailing telescope. They also installed six Voltage/Temperature Improvement Kits to prevent the telescope’s batteries from overheating as they aged. The excursion lasted eight hours 15 minutes, at the time the second longest spacewalk.
During the second spacewalk, astronauts C. Michael Foale, left, and Claude Nicollier during the changeout of the fine guidance sensor. Foale at the end of the Remote Manipulator System services the Hubble Space Telescope. The next day, Nicollier and Foale conducted the mission’s second spacewalk. The main task for this excursion involved installing a new computer aboard Hubble, replacing the original 1970s vintage unit. The new radiation-hardened system ran 20 times faster and carried six times more memory while using one-third the electrical power. They also installed a fine guidance sensor before concluding the eight-hour 10-minute spacewalk.
Astronauts Steven L. Smith, left, and John M. Grunsfeld begin their servicing activities during the third spacewalk. At the end of the third and final spacewalk, Grunsfeld, left, and Smith provide closing comments about the work the mission accomplished to service the Hubble Space Telescope. Smith and Grunsfeld ventured outside for a second time to complete the flight’s third and final spacewalk on Dec. 24, the first spacewalk conducted on Christmas Eve day. First, they replaced an old reel-to-reel tape recorder with a solid state unit providing a 10-fold increase in recording capability and replaced a failed data transmitter. They installed seven new covers on Hubble’s electronics bay doors for added protection of the telescope’s insulation. This third spacewalk lasted eight hours eight minutes.

The next day, the STS-103 astronauts earned the distinction as the first space shuttle crew to spend Christmas Day in space. Clervoy grappled Hubble, lifted it out of the payload bay and released it to continue its mission. Hubble Space Telescope Program Manager John H. Campbell said after the release, “The spacecraft is being guided by its new gyros under the control of its brand new computer. [It] is now orbiting freely and is in fantastic shape.” After deploying Hubble, the astronauts enjoyed a well-deserved Christmas dinner, with Clervoy providing French delicacies. The crew spent Dec. 26 readying Discovery for its return to Earth, including testing its reaction control system thrusters and aerodynamic surfaces and stowing unneeded gear.

Space shuttle Discovery makes a perfect night landing at NASA’s Kennedy Space Center in Florida. The crew welcome home ceremony at Ellington Field in Houston. On Dec. 27, the astronauts donned their launch and entry suits and prepared for the return to Earth. They closed the payload bay doors and fired Discovery’s engines to bring them out of orbit. Just before landing, Kelly lowered the craft’s landing gear and Brown guided Discovery to a smooth night landing at KSC, concluding a flight of seven days, 23 hours, 11 minutes. They circled the Earth 119 times. The flight marked Discovery’s last solo flight as all its subsequent missions docked with the International Space Station. Workers at KSC began readying it for its next mission, STS-92 in October 2000.
The Hubble Space Telescope continues to operate today, far exceeding the five-year life extension expected from the last of the servicing missions in 2009. Joined in space by the James Webb Space Telescope in 2021, the two instruments together continue to image the skies across a broad range of the electromagnetic spectrum to provide scientists with the tools to gain unprecedented insights into the universe and its formation.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
The Orion Environmental Test Article photographed inside the Thermal Vacuum Chamber on April 11, 2024, in the Space Environments Complex at NASA’s Neil Armstrong Test Facility in Sandusky, Ohio. Credit: NASA/Quentin Schwinn Making the voyage 1.4 million miles around the Moon and back — the farthest a spacecraft built for humans has ever gone — the Orion spacecraft has faced a battery of tests over the years. Though Orion successfully proved its capabilities in the harsh environment of space during the Artemis I mission, Orion’s evaluation did not end at splashdown.
The crew module, now known as the Orion Environmental Test Article (ETA), returned to NASA’s Neil Armstrong Test Facility in Sandusky, Ohio, in January 2024 and completed an 11-month test campaign necessary for the safety and success of Artemis II, the first crewed mission under NASA’s Artemis campaign.
Engineers and technicians from NASA and Lockheed Martin subjected the test article to the extreme conditions Orion may experience in a launch abort scenario. In the event of an emergency, Orion — and astronauts inside — will jettison away from the SLS (Space Launch System) rocket for a safe landing in the ocean.
Experts at NASA’s Neil Armstrong Test Facility in Sandusky, Ohio, conducted a lightning test, which simulates the electromagnetic effects of a lightning strike to the vehicle on the launch pad awaiting liftoff. The Feb. 20, 2024 test proved the grounding path of the vehicle is operating as designed and protecting the vehicle from damage to any of its equipment or systems. Credit: NASA/Quentin Schwinn Experts installed NASA’s Launch Abort System, designed to carry the crew to safety in the event of an emergency during launch or ascent. The Orion test article was subjected to acoustic levels simulating both a nominal ascent and a launch abort scenario. The acoustic test chamber at NASA’s Neil Armstrong Test Facility in Sandusky, Ohio, blasted the test article at a volume of almost 164 decibels on Sept. 9, 2024. Credit: NASA/Jordan Salkin On Nov. 11, 2024, experts successfully at NASA’s Neil Armstrong Test Facility completed the docking mechanism jettison test, designed to connect and disconnect the Orion spacecraft to Gateway, a small space station that will orbit the Moon. They also completed the forward bay cover jettison test on Nov. 23, 2024, which is the last piece that must eject right before parachutes deploy, and successfully tested Orion’s uprighting system. Credit: NASA/Jordan Salkin “This event would be the maximum stress and highest load that any of the systems would see,” said Robert Overy, Orion ETA project manager, NASA’s Glenn Research Center in Cleveland. “We’re taking a proven vehicle from a successful flight and pushing it to its limits. The safety of the astronaut crew depends on this test campaign.”
Experts conducted tests that simulated the noise levels of an abort during launch in addition to the electromagnetic effects of lightning strikes. The test campaign also jettisoned the test article’s docking module and parachute covers, as well as the crew module uprighting system, which consists of five airbags on top of the spacecraft that inflate upon splashdown.
“It’s been a successful test campaign,” Overy said. “The data has matched the prediction models, and everything operated as expected after being subjected to nominal and launch abort acoustic levels. We are still analyzing data, but the preliminary results show the vehicle and facility operated as desired.”
On. Nov. 23, 2024, after subjecting the Orion test article to launch abort-level acoustics, experts tested the functionality of the forward bay cover, which is the last piece that must eject before parachutes deploy. Credit: NASA/Jordan Salkin and Quentin Schwinn Testing Orion at such high acoustic levels was a major milestone for Artemis. The Reverberant Acoustic Test Facility, the world’s most powerful spacecraft acoustic test chamber, was built in 2011 in anticipation of this specific test campaign.
“These tests are absolutely critical because we have to complete all of these tests to say the spacecraft design is safe and we’re ready to fly a crew for the first time on Artemis II,” said Michael See, ETA vehicle manager, Orion Program. “This is the first time we’ve been able to test a spacecraft on the ground in such an extreme abort-level acoustic environment.”
The Orion Environmental Test Article with Launch Abort System installed moves to the Reverberant Acoustic Test Facility, the most powerful spacecraft acoustic test chamber in the world, on Sept. 9, 2024, at NASA’s Neil Armstrong Test Facility in Sandusky, Ohio. Credit: NASA/Jordan Salkin and Quentin Schwinn Part of NASA Glenn, Armstrong Test Facility is home to the world’s largest and most powerful space environment simulation chambers capable of testing full-sized spacecraft for all the extreme conditions of launch and spaceflight. The facility not only houses an acoustic test chamber, but also a thermal-vacuum chamber and spacecraft vibration system.
“The facility is unique because there’s no other place in the world capable of testing spacecraft like this,” Overy said. “Armstrong Test Facility is a one-stop-shop for all your testing needs to prepare your spacecraft for the severe and challenging journey to and from space.”
Orion’s Round-Trip Journey to Ohio
This is not the first time Orion has been inside the walls of the Space Environments Complex at Armstrong Test Facility. The spacecraft underwent mission-critical testing in 2019, where it was subjected to extreme temperatures and an electromagnetic environment before it launched on Artemis I in 2022.
“I remember when it first arrived, the gravity of its importance really hit home,” said Joshua Pawlak, test manager, NASA Glenn. “I thought to myself, on future Artemis missions, astronauts will be inside Orion heading to the Moon, and they’ll be depending on it for survival.”
Pawlak was a mechanical test engineer when Orion made its first trip to the Sandusky facility. He participated in planning and coordinating testing of the vehicle and trained personnel. He managed the vehicle from the moment it arrived, through testing, and up until it departed for NASA’s Kennedy Space Center in Florida.
Joshua Pawlak poses in front of the Artemis I Space Launch System rocket on Nov. 16, 2022, in Cape Canaveral, Florida. Credit: Joshua Pawlak “When it returned, I felt like I had a small part in this really big and exciting thing,” Pawlak said. “Seeing it come back blackened and scarred from the harsh environment of space was incredible. Space is not a friendly space, and I felt proud knowing that if there were astronauts on that vehicle, they would have survived.
After the Orion test article departs from Glenn, it will head to Kennedy for additional testing.
“When Artemis II launches and those astronauts are sitting on board, I’ll know that I did everything I could to ensure the vehicle is ready for them and going to perform as expected,” Pawlak said. “That’s why I do what I do.”

5 Min Read NASA DAVINCI Mission’s Many ‘Firsts’ to Unlock Venus’ Hidden Secrets
The surface of Venus is an inferno with temperatures hot enough to melt lead. This image is a composite of data from NASA’s Magellan spacecraft and Pioneer Venus Orbiter. Credits:
NASA/JPL-Caltech NASA’s DAVINCI — Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging — mission embodies the spirit of innovation and exploration that its namesake, Leonardo da Vinci, was famous for.
Scheduled to launch in the early 2030s, DAVINCI will explore Venus with both a spacecraft and a descent probe. DAVINCI’s probe will be the first in the 21st century to brave Venus’ atmosphere as it descends from above the planet’s clouds down to its surface. Two other missions, NASA’s VERITAS and ESA’s (European Space Agency) Envision, will also explore Venus in the 2030s from the planet’s orbit.
The DAVINCI spacecraft will study Venus’ clouds and highlands during two flybys. It also will release a spherical probe, about 3 feet wide, that will plunge through the planet’s thick atmosphere and corrosive clouds, taking measurements and capturing high-resolution images of the Venusian surface as it descends below the clouds.
Here are some of DAVINCI’s coming “firsts” in Venus exploration:
Exploring Solar System’s One-of-a-Kind Terrain
The DAVINCI mission will be the first to closely explore Alpha Regio, a region known as a “tessera.” So far found only on Venus, where they make up about 8% of the surface, tesserae are highland regions similar in appearance to rugged mountains on Earth. Previous missions discovered these features using radar instruments, but of the many international spacecraft that dove through Venus’ atmosphere between 1966 and 1985, none studied or photographed tesserae.
Thought to be ancient continents, tesserae like Alpha Regio may be among the oldest surfaces on the planet, offering scientists access to rocks that are billions of years old.
By studying these rocks from above Alpha Regio, DAVINCI scientists may learn whether ancient Venus had continents and oceans, and how water may have influenced the surface.
Photographing One of the Oldest Surfaces on Venus
The DAVINCI probe will capture the first close-up views of Alpha Regio with its infrared and optical cameras; these will also be the first photos of the planet’s surface taken in more than 40 years.
With surface temperatures reaching 900° F and air pressure 90 times that of Earth’s, Venus’ harsh environment makes exploration challenging, while its opaque atmosphere obscures direct views. Typically, scientists rely on radar instruments from Earth or Venus-orbiting spacecraft to study its terrain.
But DAVINCI’s probe will descend through the atmosphere and below the clouds for a clear view of the mountains and plains. It will capture images comparable to an airplane’s landing view of Earth’s surface. Scientists will use the photos to compile 3D maps of Alpha Regio that will provide more detail than ever of Venus’ terrain, helping them look for rocks that are usually only made in association with water.
Unveiling Secrets of Venus’ Mysterious Lower Atmosphere
The DAVINCI mission will be the first to analyze the chemical composition of Venus’ lower atmosphere through measurements taken at regular intervals, starting from approximately 90,000 feet above the surface and continuing until just before impact.
This region is critical because it contains gases and chemical compounds that may originate from Venus’ lower clouds, surface, or even subsurface.
For example, sulfur compounds detected here could indicate whether Venusian volcanoes are currently active or were active in the recent past. Noble gases (like helium or xenon), on the other hand, remain chemically inert and maintain stable concentrations, offering invaluable clues about Venus’ ancient history, such as the planet’s past water inventory.
By comparing Venus’ noble gas composition with that of Earth and Mars, scientists can better understand why these planets — despite forming from similar starting materials — evolved into dramatically different worlds.
Moreover, DAVINCI’s measurements of isotopes and trace gases in the lower atmosphere will shed light on Venus’ water history, from ancient times to the present, and the processes that triggered the planet’s extreme greenhouse effect.
State-of-the-Art Technology to Study Venus in Detail
Thanks to modern technology, the DAVINCI probe will be able to do things 1980s-era spacecraft couldn’t.
The descent probe will be better equipped than previous probes to protect the sensitive electronics inside of it, as it will be lined on the inside with high-temperature, multi-layer insulation — layers of advanced ceramic and silica fabrics separated by aluminum sheets.
Venus’ super thick atmosphere will slow the probe’s descent, but a parachute will also be released to slow it down further. Most Earth-friendly parachute fabrics, like nylon, would dissolve in Venus’ sulfuric acid clouds, so DAVINCI will have to use a different type of material than previous Venus missions did: one that’s resistant to acids and five times stronger than steel.

A new American human-rated spacecraft made its first foray into space on Dec. 5, 2014. Under contract to NASA, Lockheed Martin builds Orion as the vehicle to take American astronauts back to the Moon and eventually beyond. Orion’s overall shape harkens back to the Apollo Command and Service Modules, but using today’s technology is a larger and far more capable vehicle for NASA’s Artemis Program.
Orion’s first mission, called Engineering Flight Test-1 (EFT-1), used a Delta-IV Heavy booster, at the time the most powerful operational rocket. The 4.5-hour mission demonstrated Orion’s space-worthiness, tested the spacecraft’s heat shield during reentry into the Earth’s atmosphere, and proved the capsule’s recovery systems. Although the EFT-1 mission didn’t include a crew, the Orion capsule flew higher and faster than any human-rated spacecraft in more than 40 years.
The United Launch Alliance Delta IV Heavy rocket with NASA’s Orion spacecraft mounted atop, lifts off from Cape Canaveral Air Force Station’s Space Launch Complex 37B in Florida.NASA/Bill Ingalls At 7:05 a.m. EST on Dec. 5, 2014, the three-core first stage of the Delta-IV Heavy rocket ignited, lifting the Orion spacecraft off from Launch Complex 37B at Cape Canaveral Air Force, now Space Force, Station (CCAFS) in Florida to begin the EFT-1 mission. Three minutes and fifty-eight seconds after liftoff, the two side boosters separated as the center core continued firing for another 93 seconds. The second stage ignited thirteen seconds after separation to begin the first of three planned burns. During the first burn, the Service Module’s protective fairing separated, followed by the Launch Abort System. Lasting about 11 and a half minutes, this first burn of the second stage placed the spacecraft into a preliminary 115-by-552-mile parking orbit. While completing one revolution around the Earth, controllers in Mission Control at NASA’s Johnson Space Center in Houston, led by Flight Director Michael L. Sarafin, verified the functioning of the spacecraft’s systems. The second stage ignited a second time, firing for 4 minutes and 42 seconds to raise Orion’s apogee or high point above the Earth to 3,600 miles. During the coast to apogee, Orion remained attached to the second stage and completed its first crossing through the inner Van Allen radiation belt.
Mission Control at NASA’s Johnson Space Center in Houston, Texas during the EFT-1 mission.NASA/Mark Sowa Three hours and five minutes after launch, Orion reached its apogee and began its descent back toward Earth, separating from the second stage about 18 minutes later. The second stage conducted a one-minute disposal burn to ensure it didn’t interfere with the spacecraft’s trajectory. During the passage back through the Van Allen belt, Orion fired its thrusters for 10 seconds to adjust its course for reentry. At an altitude of 400,000 feet, the spacecraft encountered the first tendrils of the Earth’s atmosphere at a point called Entry Interface, traveling at 20,000 miles per hour (mph). A buildup of ionized gases caused by the reentry heating resulted in a communications blackout with Orion for about two and a half minutes. The spacecraft experienced maximum heating of about 4,000 degrees Fahrenheit, proving the worthiness of the heat shield. After release of Orion’s forward bay cover, two drogue parachutes deployed to slow and stabilize the spacecraft. Next followed deployment of the three main parachutes that slowed the spacecraft to 20 mph. Splashdown occurred 4 hours and 24 minutes after launch about 600 miles southwest of San Diego, California. A video of the Orion EFT-1 mission can be viewed here.

Anchorage (LPD-23) stepped into action, first placing a flotation collar around the spacecraft. After securing a tow line to the capsule, the sailors towed it aboard the amphibious well deck of Anchorage, which set sail for Naval Base San Diego arriving there on Dec 8. Engineers from NASA and Lockheed Martin conducted a preliminary inspection of the spacecraft during the cruise to San Diego and found that it survived its trip into space in excellent condition.

U.S. Navy The Orion EFT-1 mission met all its objectives and received many accolades. “Today was a great day for America,” said Flight Director Sarafin from his console at Mission Control. “It is hard to have a better day than today,” said Mark S. Geyer, Orion program manager. “We’re already working on the next capsule,” said W. Michael “Mike” Hawes, Lockheed Martin’s Orion program manager, adding, “We’ll learn a tremendous amount from what we did today.” NASA Associate Administrator for Human Exploration and Operations William H. Gerstenmaier praised all personnel involved with the EFT-1 mission, “What a tremendous team effort.” NASA Administrator Charles F. Bolden summarized his thoughts about the mission, “Today’s flight test of Orion is a huge step for NASA and a really critical part of our work to pioneer deep space.”

Bolden inspects Orion EFT-1 capsule at NASA’s Kennedy Space Center in Florida.NASA After its arrival at Naval Base San Diego, workers placed the Orion capsule aboard a truck that delivered it to NASA’s Kennedy Space Center (KSC) in Florida on Dec. 18. After engineers conducted a thorough inspection of the spacecraft at KSC, workers trucked it to the Lockheed Martin facility in Littleton, Colorado, where it arrived on Sept. 1, 2015. Engineers completed final inspections and decontamination of the vehicle. The KSC Visitor Complex has the capsule on display.

NASA The next time an Orion spacecraft flew in space during the Artemis I mission, the Space Launch System (SLS) carried it into orbit after launch from KSC’s Launch Complex 39B. The thunderous night launch took place on Nov. 16, 2022. The first in a series of increasingly complex missions, Artemis I provided a foundation for human deep space exploration and demonstrated our commitment and capability to extend human existence to the Moon and beyond. The uncrewed Orion spacecraft spent 25.5 days in space, including 6 days in a retrograde orbit around the Moon, concluding with a splashdown in the Pacific Ocean on Dec. 11, exactly 50 years after the Apollo 17 Moon landing.
The Artemis II crew poses in front of the Orion capsule at NASA’s Kennedy Space Center in Florida.NASA/Kim Shiflett On April 3, 2023, NASA named the four-person crew for the Artemis II mission, the first flight to take humans beyond low Earth orbit since Apollo 17 in December 1972. The crew includes NASA astronauts G. Reid Wiseman as commander, Victor J. Glover as pilot, and Christina H. Koch as a mission specialist as well as Canadian Space Agency astronaut Jeremy R. Hansen as the other mission specialist. The four will take an Orion spacecraft on a 10-day journey around the Moon to human rate the spacecraft and SLS.
