Agency experts will preview NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) mission, which will help scientists better understand the structure of the universe, how galaxies form and evolve, and the origins and abundance of water. Launch is targeted for no earlier than Thursday, Feb. 27.
The news conference will be hosted at the agency’s Jet Propulsion Laboratory in Southern California. Watch live on NASA+, as well as JPL’s X and YouTube channels. Learn how to watch NASA content through a variety of platforms, including social media.
Laurie Leshin, director, NASA JPL, will provide opening remarks. Additional briefing participants include:
Shawn Domagal-Goldman, acting director, Astrophysics Division, NASA Headquarters James Fanson, project manager, SPHEREx, NASA JPL Beth Fabinsky, deputy project manager, SPHEREx, NASA JPL Jamie Bock, principal investigator, SPHEREx, Caltech Cesar Marin, SPHEREx integration engineer, Launch Services Program, NASA’s Kennedy Space Center in Florida To ask questions by phone, members of the media must RSVP no later than two hours before the start of the event to: rexana.v.vizza@jpl.nasa.gov. NASA’s media accreditation policy is available online. Questions also can be asked on social media during the briefing using #AskNASA.
The SPHEREx observatory will survey the entire celestial sky in near-infrared light to help answer cosmic questions involving the birth of the universe, and the subsequent development of galaxies. It also will search for ices of water and organic molecules — essentials for life as we know it — in regions where stars are born from gas and dust, as well as disks around stars where new planets could be forming. Astronomers will use the mission to gather data on more than 450 million galaxies, as well as more than 100 million stars in our own Milky Way galaxy.
The space observatory will share its ride on a SpaceX Falcon 9 rocket with NASA’s PUNCH (Polarimeter to Unify the Corona and Heliosphere) mission, which will lift off from Launch Complex 4E at Vandenberg Space Force Base in Central California.
The SPHEREx mission is managed by NASA JPL for the agency’s Astrophysics Division within the Science Mission Directorate at NASA Headquarters in Washington. The principal investigator is based at Caltech in Pasadena, California, which manages NASA JPL for the agency.
The spacecraft is supplied by BAE Systems. The Korea Astronomy and Space Science Institute contributed the non-flight cryogenic test chamber. Mission data will be publicly available through IPAC at Caltech.

4 Min Read NASA 3D-Printed Antenna Takes Additive Manufacturing to New Heights
The 3D-printed antenna mounted to a ladder prior to testing at NASA's Columbia Scientific Balloon Facility in Palestine, Texas. Credits: NASA/Peter Moschetti In fall 2024, NASA developed and tested a 3D-printed antenna to demonstrate a low-cost capability to communicate science data to Earth. The antenna, tested in flight using an atmospheric weather balloon, could open the door for using 3D printing as a cost-effective development solution for the ever-increasing number of science and exploration missions.

NASA developed and tested a 3D-printed antenna to demonstrate a low-cost capability to communicate science data to Earth.NASA/Kasey Dillahay Printing
For this technology demonstration, engineers from NASA’s Near Space Network designed and built a 3D-printed antenna, tested it with the network’s relay satellites, and then flew it on a weather balloon.
The 3D printing process, also known as additive manufacturing, creates a physical object from a digital model by adding multiple layers of material on top of each other, usually as a liquid, powder, or filament. The bulk of the 3D-printed antenna uses a low electrical resistance, tunable, ceramic-filled polymer material.
Using a printer supplied by Fortify, the team had full control over several of the electromagnetic and mechanical properties that standard 3D printing processes do not. Once NASA acquired the printer, this technology enabled the team to design and print an antenna for the balloon in a matter of hours. Teams printed the conductive part of the antenna with one of several different conductive ink printers used during the experiment.
For this technology demonstration, the network team designed and built a 3D-printed magneto-electric dipole antenna and flew it on a weather balloon. [JF1] A dipole antenna is commonly used in radio and telecommunications. The antenna has two “poles,” creating a radiation pattern similar to a donut shape.
Testing
The antenna, a collaboration between engineers within NASA’s Scientific Balloon Program and the agency’s Space Communications and Navigation (SCaN) program, was created to showcase the capabilities of low-cost design and manufacturing.
Following manufacturing, the antenna was assembled and tested at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, in the center’s electromagnetic anechoic chamber.
The anechoic chamber is the quietest room at Goddard — a shielded space designed and constructed to both resist intrusive electromagnetic waves and suppress their emission to the outside world. This chamber eliminates echoes and reflections of electromagnetic waves to simulate the relative “quiet” of space.
To prepare for testing, NASA intern Alex Moricette installed the antenna onto the mast of the anechoic chamber. The antenna development team used the chamber to test its performance in a space-like environment and ensure it functioned as intended.

The team coordinated links with the Near Space Network’s relay fleet to test the 3D-printed antenna’s ability to send and receive data.
The team monitored performance by sending signals to and from the 3D-printed antenna and the balloon’s planned communications system, a standard satellite antenna. Both antennas were tested at various angles and elevations. By comparing the 3D-printed antenna with the standard antenna, they established a baseline for optimal performance.

During flight, the weather balloon and hosted 3D-printed antenna were tested for environmental survivability at 100,000 feet and were safely recovered.
For decades, NASA’s Scientific Balloon Program, managed by NASA’s Wallops Flight Facility in Virginia, has used balloons to carry science payloads into the atmosphere. Weather balloons carry instruments that measure atmospheric pressure, temperature, humidity, wind speed, and direction. The information gathered is transmitted back to a ground station for mission use.
The demonstration revealed the team’s anticipated results: that with rapid prototyping and production capabilities of 3D printing technology, NASA can create high-performance communication antennas tailored to mission specifications faster than ever before.
Implementing these modern technological advancements is vital for NASA, not only to reduce costs for legacy platforms but also to enable future missions.
The Near Space Network is funded by NASA’s SCaN (Space Communications and Navigation) program office at NASA Headquarters in Washington. The network is operated out of NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
