This photo shows the Wide Field Instrument for NASA’s Nancy Grace Roman Space Telescope arriving at the big clean room at NASA’s Goddard Space Flight Center. About the size of a commercial refrigerator, this instrument will help astronomers explore the universe’s evolution and the characteristics of worlds outside our solar system. Unlocking these cosmic mysteries and more will offer a better understanding of the nature of the universe and our place within it.NASA/Chris Gunn The primary instrument for NASA’s Nancy Grace Roman Space Telescope is a sophisticated camera that will survey the cosmos from the outskirts of our solar system all the way out to the edge of the observable universe. Called the Wide Field Instrument, it was recently delivered to the agency’s Goddard Space Flight Center in Greenbelt, Maryland.
The camera’s large field of view, sharp resolution, and sensitivity from visible to near-infrared wavelengths will give Roman a deep, panoramic view of the universe. Scanning much larger portions of the sky than astronomers can with NASA’s Hubble or James Webb space telescopes will open new avenues of cosmic exploration. Roman is designed to study dark energy (a mysterious cosmic pressure thought to accelerate the universe’s expansion), dark matter (invisible matter seen only via its gravitational influence), and exoplanets (worlds beyond our solar system).
“This instrument will turn signals from space into a new understanding of how our universe works,” said Julie McEnery, the Roman senior project scientist at Goddard. “To achieve its main goals, the mission will precisely measure hundreds of millions of galaxies. That’s quite a dataset for all kinds of researchers to pull from, so there will be a flood of results on a vast array of science.”

The WFI’s design was a collaborative effort between Goddard and BAE Systems in Boulder, Colorado. Teledyne Imaging Sensors, Hawaii Aerospace Corporation, Applied Aerospace Structures Corporation, Northrop Grumman, Honeybee Robotics, CDA Intercorp, Alluxa, and JenOptik provided critical components. Those parts and many more, made by other vendors, were delivered to Goddard and BAE Systems, where they were assembled and tested prior to the instrument’s delivery to Goddard this month.
“I am so happy to be delivering this amazing instrument,” said Mary Walker, Roman’s Wide Field Instrument manager at Goddard. “All the years of hard work and the team’s dedication have brought us to this exciting moment.”
NASA’s Nancy Grace Roman Space Telescope is a next-generation observatory that will survey the infrared universe from beyond the orbit of the Moon. The spacecraft’s giant camera, the Wide Field Instrument, will be fundamental to this exploration. Data it gathers will enable scientists to discover new and uniquely detailed information about planetary systems around other stars. The instrument will also map how matter is structured and distributed throughout the cosmos, which could ultimately allow scientists to discover the fate of the universe. Watch this video to see a simplified version of how the Wide Field Instrument works.
NASA’s Goddard Space Flight Center Seeing the Bigger Picture
After Roman launches by May 2027, each of the Wide Field Instrument’s 300-million-pixel images will capture a patch of the sky bigger than the apparent size of a full moon. The instrument’s large field of view will enable sweeping celestial surveys, revealing billions of cosmic objects across vast stretches of time and space. Astronomers will conduct research that could take hundreds of years using other telescopes.
And by observing from space, Roman’s camera will be very sensitive to infrared light –– light with longer wavelengths than our eyes can see –– from far across the cosmos. This ancient cosmic light will help scientists address some of the biggest cosmic mysteries, one of which is how the universe evolved to its present state.
From the telescope, light’s path through the instrument begins by passing through one of several optical elements in a large wheel. These elements include filters, which allow specific wavelengths of light to pass through, and a grism and prism, which split light into all of its individual colors. These detailed patterns, called spectra, reveal information about the object that emitted the light.
Then, the light travels on toward the camera’s set of 18 detectors, which each contain 16 million pixels. The large number of detectors and pixels gives Roman its large field of view. The instrument is designed for accurate, stable images and exquisite precision in measuring the exact amount of light in every pixel of every image, giving Roman unprecedented power to study dark energy. The detectors will be held at about minus 300 degrees Fahrenheit (minus 184 degrees Celsius) to increase sensitivity to the infrared universe.
“When the light reaches the detectors, that marks the end of what may have been a 10-billion-year journey through space,” said Art Whipple, an aerospace engineer at Goddard who has contributed to the Wide Field Instrument’s design and construction for more than a decade.
Once Roman begins observing, its rapid data delivery will require new analysis techniques.
“If we had every astronomer on Earth working on Roman data, there still wouldn’t be nearly enough people to go through it all,” McEnery said. “We’re looking at modern techniques like machine learning and artificial intelligence to help sift through Roman’s observations and find where the most exciting things are.”
Now that the Wide Field Instrument is at Goddard, it will be tested to ensure everything is operating as expected. It will be integrated onto the instrument carrier and mated to the telescope this fall, bringing scientists one step closer to making groundbreaking discoveries for decades to come.

On March 24, 1979, space shuttle Columbia arrived at NASA’s Kennedy Space Center (KSC) for the very first time. Following Presidential direction to build the space shuttle in 1972, Congress quickly approved and funded the program later that year. Construction of the first orbital vehicle, later named Columbia, began in 1975. Four years later, Columbia completed its first transcontinental flight, arriving at KSC to begin preparations for its first mission. The first shuttle flight in April 1981 ushered in an era of reusable space transportation.
Left: NASA Administrator James C. Fletcher, left, presents a model of the space shuttle to President Richard M. Nixon in January 1972. Right: Apollo 16 astronauts John W. Young, left, and Charles M. Duke on the Moon in April 1972.
On Jan. 5, 1972, President Richard M. Nixon directed NASA to build the space shuttle, formally called the Space Transportation System (STS), stating that “it would revolutionize transportation into near space.” NASA Administrator James C. Fletcher hailed the President’s decision as “an historic step in the nation’s space program,” adding that it would change what humans can accomplish in space. Apollo 16 astronauts John W. Young and Charles M. Duke learned of the space shuttle’s approval while exploring the Moon in April 1972. Mission Control informed them that Congress had authorized the development of the space shuttle. Young and Duke both enthusiastically responded to the positive news with “Beautiful! Wonderful! Beautiful!” Young added with some foresight, “The country needs that shuttle mighty bad. You’ll see.” He had no way of knowing that nine years later, he would command the first ship of the space shuttle fleet, Columbia, on its maiden voyage.

Once Congress authorized the funds, on July 26, 1972, NASA awarded the contract to the North American Rockwell Corporation of Downey, California, to begin construction of the first orbital vehicle. Officially known as Orbital Vehicle-102 (OV-102), in January 1979 NASA named it Columbia after Captain Robert Gary’s sloop that explored the Pacific Northwest in the 1790s and took the honor as the first American ship to circumnavigate the globe, as well as after the Apollo 11 Command Module. Construction of Columbia’s first components at Rockwell’s Palmdale, California, plant began on March 25, 1975.
Left: Workers roll Columbia out from its hangar at Rockwell’s Palmdale, California, plant. Middle: Workers transport Columbia from Rockwell’s Palmdale facility to NASA’s Dryden, now Armstrong, Flight Research Center. Right: Columbia atop the Shuttle Carrier Aircraft takes off from Dryden to begin the cross-country ferry flight.
Nearly four years later, on March 8, 1979, Columbia rolled out of the Palmdale facility to begin its multi-day transcontinental journey to KSC. For the first step of the journey, workers towed Columbia from Palmdale overland to NASA’s Dryden, now Armstrong, Flight Research Center at Edwards Air Force Base (AFB) 36 miles away. Two days later, workers there hoisted Columbia onto the Shuttle Carrier Aircraft (SCA), a Boeing 747 aircraft modified to transport space shuttle orbiters. During a test flight, thousands of the orbiter’s thermal protection system tiles fell off. Workers returned Columbia to a hangar where over 100 men and women worked for nine days reapplying the tiles. Weather then delayed Columbia’s departure until March 20, when the SCA/shuttle duo flew from Dryden to Biggs AFB in El Paso, Texas.

Right: Tina Aguilar, age nine, an aspiring young reporter, interviews astronaut Donald K. “Deke” Slayton in front of Columbia and the SCA at Kelly AFB.
Weather delayed Columbia’s departure for the planned refueling stop at Kelly AFB in San Antonio, until the next day. About 200,000 people went to view the shuttle during its overnight layover in San Antonio prior to its departure on March 23.

Frosch addresses the crowd assembled to welcome Columbia to KSC, as other dignitaries listen.
After another overnight stop at Eglin AFB in Florida, Columbia atop the SCA touched down at KSC’s Shuttle Landing Facility (SLF) on March 24, a crowd of about 3,000 cheering its arrival. Dignitaries in attendance at a brief welcoming ceremony at the SLF included NASA Administrator Robert A. Frosch, KSC Director Lee R. Scherer, SCA pilots Joseph S. Algranti and Fitzhugh L. Fulton, program manager for Shuttle Flight Test Operations NASA astronaut Donald K. “Deke” Slayton, and astronauts John W. Young and Robert L. Crippen, designated as the commander and pilot for STS-1, the first space shuttle mission. Also in attendance, U.S. Congressman C. William “Bill” Nelson whose district included KSC and now serves as NASA’s 14th administrator, and Florida Lieutenant Governor J. Wayne Mixson.

The next day, after removing Columbia from the back of the SCA, workers towed it into the Orbiter Processing Facility, where the orbiter spent the next 19 months preparing for its first flight. Rollover to the Vehicle Assembly Building (VAB) for mating with its External Tank and the two Solid Rocket Boosters took place Nov. 24, 1980. After a series of integrated tests, the shuttle stack rolled out of the VAB and made the 3.5-mile trip to Launch Pad 39A on Dec. 29, 1980. Young and Crippen flew Columbia’s historic first mission, STS-1, in April 1981, ushering in an era of reusable space transportation.

Video: 00:02:10 The largest components for the first flight model of Europe’s new rocket Ariane 6 arrived at the port of Pariacabo in Kourou, French Guiana on 21 February 2024 via the novel ship, Canopée (canopy in French).
The Ariane 6 stages and components are all manufactured across Europe. On this trip, Canopée brought the central core for Ariane 6’s first flight. The main engine and the main stage were integrated in Les Mureaux, France, while the upper stage and insulation for the rocket’s exterior were built up in Bremen, Germany.
The various Ariane 6 components are then offloaded and transported by road to the new Ariane 6 launch vehicle assembly building just a few kilometres away. Here, the launcher stages are unpacked and installed on the assembly line for integration, and finally, liftoff.
The Ariane 6 boosters are already in Europe’s Spaceport after their production in Italy, they are the same P120C solid propulsion boosters as used for Europe’s Vega-C rocket.
First the central core will be assembled horizontally after which it is transported to the launchpad. Here it will be lifted into the upright position after which Boosters and the upper stage will be added inside the mobile gantry.
This summer Flight Model-1 will be ready to let its engine rumble and fly.
