NASA’s Next-Generation Telescope Arrives in Florida Ahead of Launch (News Release)

NASA’s Nancy Grace Roman Space Telescope arrived at the agency’s Kennedy Space Center in Florida on June 21, marking the start of final prelaunch preparations before liftoff later this summer.

After teams completed integration and testing on the observatory at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, they loaded Roman into a protective and environmentally-controlled transportation container and drove it to the port of Baltimore. There, the agency’s Pegasus barge safely transported the nearly 18,000-pound (8,200-kilogram) spacecraft down the coast of the Atlantic Ocean to its new home in Florida at the Payload Hazardous Servicing Facility, which recently completed upgrades to prepare for Roman’s arrival.

Technicians met the telescope at NASA Kennedy’s turn basin wharf and offloaded the trailer carrying the observatory from the barge, where they connected it to a truck that transported Roman to the servicing facility.

When the spacecraft arrives at the facility, technicians will complete initial cleaning outside the building before moving the shipping container into the facility’s airlock. Once in the airlock, they will perform additional cleaning to reduce any remaining contaminants from the trip. The facility’s air filtration system will also scrub the air until the team can safely open the inner door.

Once inside the facility, technicians will unbox the spacecraft, raise it to a vertical position in the airlock, and move it into the clean room.

On Monday, June 22, technicians plan to remove the cover from the transport container and move Roman into the high bay. Later, technicians will use large cranes to move Roman to its work platform - called the Pantheon. During the observatory’s time at the processing facility, technicians will perform several tasks, including testing the six solar panels and inspecting Roman’s insulation and thermal blankets to ensure that the observatory is fully protected and flight ready.

Specially-trained team members will load about 290 gallons of hydrazine fuel into the spacecraft’s tanks.

NASA is targeting launch no earlier than Sunday, August 30, on a SpaceX Falcon Heavy rocket from Launch Complex 39A at Kennedy. This puts Roman eight months ahead of schedule.

After launch, Roman will travel to the second Sun-Earth Lagrange point, or L2. There, it will make observations that give astronomers the chance to study an incredible number of new objects. Roman’s wide field of view and rapid survey capabilities will reveal billions of galaxies, hundreds of thousands of new exoplanets, hundreds of blackholes, and will provide vast volumes of daily data for astronomers to study.

The observatory will also map how common different kinds of planets are in our galaxy and help answer big questions about the Universe, like what’s causing its rapid expansion and what distant worlds and cosmic objects look like in infrared light. In addition to its main instrument, which features a 300-megapixel camera, Roman will demonstrate technology designed to block starlight to directly image exoplanets and planet-forming disks.

Alongside Roman, the Pegasus barge also carried a weather cover for the Artemis III SLS (Space Launch System) core stage. The cover will protect the stage thermal systems while it sits at Launch Complex 39B in its short stack configuration. Because schedules aligned, the barge was able to transport NASA’s next flagship astrophysics mission together with the Artemis hardware, maximizing resources to support missions across the agency during the Golden Age of innovation and exploration.

Marking a Quarter Century Since the 2001 NBA Championship...

On this day 25 years ago, Kobe Bryant and the Los Angeles Lakers won their second straight NBA title in the Kobe-Shaquille O'Neal era. They went 15-1 in the playoffs that spring...sweeping the Portland Trailblazers, Sacramento Kings and San Antonio Spurs before defeating the Philadelphia 76ers in five games during the NBA Finals.

That was an awesome postseason! We'll see what the Lakers do this summer in their attempt to become the kings of the West again. And then going on to win their 18th NBA championship in franchise history.

On This Day in 1996: Cool Things Happened in High School...

Richard T. Par

Just thought I'd point out that today marks 30 years since I had my final exam that concluded 10th grade at my alma mater, Bishop Amat Memorial High School! The test that I took on June 13, 1996 was for my English II class...which I had for 7th period.

So why was this date memorable, you ask? Because of a girl I had a crush on, of course! I won't divulge her (full) name here, but she was the prettiest Filipina in my class—and probably in all of Amat, truthfully—and I was fortunate enough to have managed to be on speaking terms with her for much of sophomore year.

We hugged after the English II exam ended (she was also in my homeroom and 3rd period World History class, respectively), and that was the last time I saw her for almost the next two years. (She ended up transferring to another high school for 11th and 12th grade, but showed up at a birthday party of one Amat classmate in February of '98, and the graduation party of another classmate four months later.) This hug was so big that my brother's friends (they all graduated from Amat two weeks before) found out about it afterwards...and expressed awe at my lucky moment.

That's how significant it was that I was on good terms with Des during the 1995-'96 school year!

America's Newest X-Plane Has Finally Broken the Sound Barrier!

NASA’s X-59 Aircraft Flies Supersonic for First Time (News Release)

NASA’s experimental X-59 aircraft marked a major milestone on Friday, June 5, when it flew faster than the speed of sound for the first time, setting the stage for demonstrating its quiet supersonic capabilities later this year.

NASA test pilot Jim “Clue” Less took off and landed at Edwards Air Force Base in California, reaching a top speed of approximately Mach 1.1 (713 mph) and altitude of 43,400 feet. The X-59’s flight began at 11:08 a.m. PDT and lasted 81 minutes, with the team focusing on flying qualities at both subsonic and then supersonic speeds.

”X-59 is getting ready for its quiet supersonic debut. Since the aircraft’s first flight on October 28, 2025, the team has made tremendous progress, flying 16 times in the last 90 days and getting into a steady test rhythm. In the coming days, we expect to take the next step and push to Mach 1.4,” said NASA Administrator Jared Isaacman. “I’m grateful to the NASA team and Lockheed Martin Skunk Works for their help getting us to this point, and I hope this is the first of many collaborations as we rebuild NASA’s X-plane portfolio.”

The X-59 is designed to fly at supersonic speeds while creating only a quiet thump instead of a loud sonic boom. For this flight, a NASA F‑15 chase plane flew nearby to monitor the X‑59. The loud sonic booms from the F-15 obscured any sound made by the X-59.

This first supersonic flight is a significant milestone, but an event even more critical to the mission is upcoming. In just days, the aircraft is expected to make its first “mission conditions” flight, reaching a cruising speed of Mach 1.4 (925 mph) and altitude of approximately 55,000 feet. The X-59 will also be accompanied by a chase plane for this flight.

This speed and altitude are the base conditions for the X-59 when it will eventually fly over several U.S. communities, enabling NASA to gather data about how people may perceive its quiet thump. NASA will share this data with U.S. and international regulators to help establish new data-driven noise standards to enable a future viable market for supersonic commercial flight over land.

For the last several months, the X-59 has been participating in an ongoing series of flights where the plane has been flying at a wide range of speeds and altitudes – a process known as envelope expansion. These tests are the first phase of the X-59’s flight testing. They are focused on performance and involve chase plane monitoring.

When the X-59 completes this phase it will enter another, focused on its sound profile in order to verify its quiet thump capability.

The X-59 is the centerpiece of NASA’s QueSST mission, which aims to demonstrate quiet supersonic flight and help enable commercial supersonic flight over land worldwide. These advancements will help travelers reach their preferred destinations faster, spending less time in the air.

Through QueSST’s development of the X-59, NASA will also deliver design tools and technology for quiet supersonic airliners that will achieve the high speeds desired by commercial operators without disturbing people on the ground. NASA will validate design tools through ground and flight testing, providing U.S. aircraft manufacturers the ability to explore new quiet supersonic concepts, and provide them with confidence that their resulting designs will meet quiet flight requirements.

Hello, World! NASA Shares New Home for Roman Space Telescope Updates (News Release)

We’re kicking off the inaugural Roman blog post with a launch update: NASA’s Nancy Grace Roman Space Telescope is officially slated to launch on August 30, eight months ahead of schedule and even earlier than previously targeted.

With less than three months to go, the Roman team is now finishing up final tasks. Engineers are currently packing Roman up for a voyage from NASA’s Goddard Space Flight Center in Greenbelt, Maryland, down to the agency’s Kennedy Space Center in Florida later this month.

Once at Kennedy, Roman will move into the Payload Hazardous Servicing Facility, where it will undergo a thorough inspection to verify that all of the observatory’s components traveled well. In the weeks leading up to launch, engineers will perform powered testing and launch rehearsals, load about 290 gallons (roughly 1,100 liters) of hydrazine fuel into the tanks, and install the observatory on the adapter for the SpaceX Falcon Heavy rocket that will propel it to its destination in space: the second Sun-Earth Lagrange point, or L2, which is about four times farther away than the Moon is from Earth.

Next, Roman will be encapsulated in a protective fairing, or nose cone, which will shield the telescope during liftoff and its journey through the atmosphere. Roman will then move to a hangar for integration with the SpaceX Falcon Heavy rocket before rolling out to Launch Complex 39A at NASA Kennedy.

All this work will culminate in Roman delivering never-before seen views of the Universe. The observatory will pair a large field of view with crisp infrared vision to survey deep, vast swaths of sky. While the mission was designed with dark energy, dark matter, and planets outside our Solar System in mind, Roman’s unprecedented observational capability will offer practically limitless opportunities for astronomers to explore a broad range of cosmic phenomena.

NASA’s Dragonfly Flight System Faces Heat (News Release)

In preparation for the journey to reach the surface of Saturn’s largest moon, Titan, the heat shield for NASA’s Dragonfly mission completed thermal-structural testing in the New Mexico desert. Dragonfly team members, including those from NASA’s Ames Research Center in California’s Silicon Valley, the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, and Lockheed Martin in Littleton, Colorado, collaborated with personnel at Sandia National Laboratories’ National Solar Thermal Test Facility in Albuquerque, New Mexico, to stress-test Dragonfly’s heat shield materials, ensuring that the rotorcraft will be safely delivered through Titan’s dense atmosphere.

Dragonfly’s thermal protection material, made from carbon fiber and a lightweight resin, performed as expected in combined mechanical and thermal testing, even in cases when it was intentionally marred with defects.

Sandia’s Solar Tower test facility houses an array of hundreds of calibrated mirror-like systems to focus energy from the Sun onto a tower holding the test unit. Operators generated temperatures around 4,500° Fahrenheit (nearly 2,500° Celsius) on segments of Dragonfly’s heat shield material. Tests examined tolerance to thermal radiation as well as the rapid change in temperature that researchers expect Dragonfly to experience.

The Sandia test series involved multiple iterations in conditions like those expected during Dragonfly’s entry into Titan’s atmosphere. Additional testing subjected large samples of the heat-shield material to mechanical and thermal stress to simultaneously simulate the pressure of high-speed atmospheric entry and intense thermal conditions. Thermal testing of the heat-shield’s curved shoulder units was also performed.

“We were pleased to see the heat shield material pass these tests, even with the flaws we intentionally included, like those that might naturally occur during fabrication and integration,” said Milad Mahzari, the Dragonfly entry vehicle thermal protection system lead at NASA Ames.

Dragonfly’s heat shield uses a variation of a NASA-invented material called PICA, or Phenolic Impregnated Carbon Ablator. The original PICA material was used to deliver NASA’s Curiosity and Perseverance rovers to Mars. PICA-D, a new variant of PICA, is planned for flight on Dragonfly and was the focus of this test series.

“We tested the heat shield as a complete system, including the primary PICA-D material, gap fillers, and potential manufacturing defects,” Mahzari said, adding that researchers plan to conduct additional analysis of PICA-D before final construction of the heat shield begins.

Dragonfly rotorcraft integration and testing continues at APL, which designed Dragonfly and leads the mission for NASA. Dragonfly is scheduled to launch in 2028 and reach Titan in 2034 to conduct science across multiple locations, sample surface materials to measure their detailed compositions, and observe geology and meteorology on the only moon in the Solar System known to have a substantial atmosphere.

Communications on board

Work continues to test and integrate Dragonfly’s communications system, including the antennas that will link the rotorcraft to operators back on Earth.

The team recently measured the signal patterns coming from Dragonfly’s largest antenna – its high-gain antenna, or HGA – in an APL test chamber that simulates the space environment. The HGA is a 34.4-inch diameter radial line slot antenna, which uses many small slots working together to create a narrow, focused radio beam.

The technology for this antenna was originally developed for NASA’s DART mission and is also flying on NASA’s twin ESCAPADE spacecraft.

“A simple way to picture the antenna is as a large flat showerhead: energy enters near the center and spreads out through the slots in a controlled pattern,” said Matt Bray, Dragonfly lead antenna designer at APL. “This design provides a low-cost, durable and compact approach to high-efficiency communications in extreme space environments and also provides aerodynamic benefits.”

The HGA, Dragonfly’s primary antenna for transmitting science data, will be attached to the top deck of the lander on a gimbal that allows it to track Earth from various locations on Titan’s surface. It will be covered with Kapton, a thermal insulator, for protection from Titan’s weather and crafted to operate in the moon’s frigid environment, where ambient temperatures are 290° below zero Fahrenheit (179° below zero Celsius).

The HGA will be one of three antennas on Dragonfly designed for operations at Titan. The lander will also fly a medium-gain antenna, primarily as a backup to the HGA, and a low-gain antenna, primarily to transmit status tones during flight as well as for emergency communications.
