Preparations for Next Moonwalk Simulations Underway (and Underwater)
Ahead of launch, NASA’s SPHEREx is enclosed in a payload fairing at Vandenberg Space Force Base on March 2. The observatory is stacked atop the four small satellites that make up the agency’s PUNCH mission.NASA/BAE Systems/Benjamin Fry NASA’s latest space observatory is targeting a March 8 liftoff, and the agency’s PUNCH heliophysics mission is sharing a ride. Here’s what to expect during launch and beyond.
In a little over a day, NASA’s SPHEREx space telescope is slated to launch from Vandenberg Space Force Base in California aboard a SpaceX Falcon 9 rocket. The observatory will map the entire celestial sky four times in two years, creating a 3D map of over 450 million galaxies. In doing so, the mission will provide insight into what happened a fraction of a second after the big bang, in addition to searching interstellar dust for the ingredients of life, and measuring the collective glow from all galaxies, including ones that other telescopes cannot easily detect.
The launch window opens at 7:09:56 p.m. PST on Saturday, March 8, with a target launch time of 7:10:12 p.m. PST. Additional opportunities occur in the following days.
Launching together into low Earth orbit, NASA’s SPHEREx and PUNCH missions will study a range of topics from the early universe to our nearest star. NASA/JPL-Caltech Sharing a ride with SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) is NASA’s PUNCH (Polarimeter to Unify the Corona and Heliosphere), a constellation of four small satellites that will map the region where the Sun’s outer atmosphere, the corona, transitions to the solar wind, the constant outflow of material from the Sun.

What SPHEREx Will Do
The SPHEREx observatory detects infrared light — wavelengths slightly longer than what the human eye can see that are emitted by warm objects including stars and galaxies. Using a technique called spectroscopy, SPHEREx will separate the infrared light emitted by hundreds of millions of stars and galaxies into 102 individual colors — the same way a prism splits sunlight into a rainbow. Observing those colors separately can reveal various properties of objects, including their composition and, in the case of galaxies, their distance from Earth. No other all-sky survey has performed spectroscopy in so many wavelengths and on so many sources.
The mission’s all-sky spectroscopic map can be used for a wide variety of science investigations. In particular, SPHEREx has its sights set on a phenomenon called inflation, which caused the universe to expand a trillion-trillionfold in a fraction of a second after the big bang. This nearly instantaneous event left an impression on the large-scale distribution of matter in the universe. The mission will map the distribution of more than 450 million galaxies to improve scientists’ understanding of the physics behind this extreme cosmic event.
SPHEREx Fact Sheet Additionally, the space telescope will measure the total glow from all galaxies, including ones that other telescopes cannot easily detect. When combined with studies of individual galaxies by other telescopes, the measurement of this overall glow will provide a more complete picture of how the light output from galaxies has changed over the universe’s history.
At the same time, spectroscopy will allow SPHEREx to seek out frozen water, carbon dioxide, and other key ingredients for life. The mission will provide an unprecedented survey of the location and abundance of these icy compounds in our galaxy, giving researchers better insight into the interstellar chemistry that set the stage for life.
Launch Sequence
But, first, SPHEREx has to get into space. Prelaunch testing is complete on the spacecraft’s various systems, and it’s been encapsulated in the protective nose cone, or payload fairing, atop the SpaceX Falcon 9 rocket that will get it there from Vandenberg’s Space Launch Complex-4 East.
NASA’s SPHEREx mission will lift off from Space Launch Complex-4 East at Vanden-berg Space Force Base in California aboard a SpaceX Falcon 9 rocket, just as the Sur-face Water and Ocean Topography mission, shown here, did in December 2022. NASA/Keegan Barber A little more than two minutes after the Falcon 9 lifts off, the main engine will cut off. Shortly after, the rocket’s first and second stages will separate, followed by second-stage engine start. The reusable first stage will then begin its automated boost-back burn to the launch site for a propulsive landing.
Once the rocket is out of Earth’s atmosphere, about three minutes after launch, the payload fairing that surrounds the spacecraft will separate into two halves and fall back to Earth, landing in the ocean. Roughly 41 minutes after launch, SPHEREx will separate from the rocket and start its internal systems so that it can point its solar panel to the Sun. After this happens, the spacecraft can establish communications with ground controllers at NASA’s Jet Propulsion Laboratory in Southern California, which manages the mission for the agency. This milestone, called acquisition of signal, should happen about three minutes after separation.
About 52 minutes after liftoff, PUNCH should separate as well from the Falcon 9.
Both spacecraft will be in a Sun-synchronous low Earth orbit, where their position relative to the Sun remains the same throughout the year. Each approximately 98-minute orbit allows the SPHEREx telescope to view a 360-degree strip of the celestial sky. As Earth’s orbit around the Sun progresses, that strip slowly advances, enabling SPHEREx to image almost the entire sky in six months. For PUNCH, the orbit provides a clear view in all directions around the Sun.
About four days after launch, SPHEREx should eject the protective cover over its telescope lens. The observatory will begin science operations a little over a month after launch, once the telescope has cooled down to its operating temperature and the mission team has completed a series of checks.
NASA’s Launch Services Program, based out of the agency’s Kennedy Space Center in Florida, is providing the launch service for SPHEREx and PUNCH.

Creating a golden streak in the night sky, a SpaceX Falcon 9 rocket carrying Intuitive Machines’ Nova-C lunar lander (IM-2) and NASA’s Lunar Trailblazer soars upward after liftoff from Launch Complex 39A at NASA’s Kennedy Space Center in Florida at 7:16 p.m. EST, Wednesday, Feb. 26. The IM-2 launch, which is part of NASA’s CLPS (Commercial Lunar Payload Services) initiative, is carrying NASA technology and science demonstrations, and other commercial payloads to Mons Mouton, a lunar plateau to advance our understanding of the Moon and planetary processes, while paving the way for future crewed missions. (Credit: NASA) The next set of NASA science and technology demonstrations is on its way to the lunar surface, where they will gather data about Earth’s nearest neighbor and help pave the way for American astronauts to explore the Moon and beyond, for the benefit of all.
Carrying NASA instruments as part of the agency’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign, Intuitive Machines’ IM-2 mission launched at 7:16 p.m. EST, Feb. 26, aboard a SpaceX Falcon 9 rocket from Launch Complex 39A at the agency’s Kennedy Space Center in Florida. Intuitive Machines’ lunar lander is scheduled to touch down on Thursday, March 6, in Mons Mouton, a plateau in the Moon’s South Pole.
“With each CLPS mission, the United States is leading the way in expanding our reach and refining our capabilities, turning what was once dreams into reality,” said NASA acting Administrator Janet Petro. “These science and technology demonstrations are more than payloads – they represent the foundation for future explorers who will live and work on the Moon. By partnering with American industry, we are driving innovation, strengthening our leadership in space, and preparing for sending humans farther into the solar system, including Mars.”

Credit: Intuitive Machines Once on the Moon, the NASA CLPS investigations will aim to measure the potential presence of volatiles or gases from lunar soil – one of the first on-site demonstrations of resource use on the Moon. In addition, a passive Laser Retroreflector Array on the top deck of the lander will bounce laser light back at any future orbiting or incoming spacecraft to give them a permanent reference point on the lunar surface. Other technology instruments on this delivery will demonstrate a robust surface communications system and deploy a propulsive drone designed to hop across the lunar surface.
NASA’s Lunar Trailblazer spacecraft, which launched as a rideshare with the IM-2 mission, also began its journey to lunar orbit, where it will map the distribution of the different forms of water on the Moon. Lunar Trailblazer will discover where the Moon’s water is, what form it is in, and how it changes over time. Observations gathered during its two-year prime mission will contribute to the understanding of water cycles on airless bodies throughout the solar system while also supporting future human and robotic missions to the Moon by identifying where water is located.
NASA’s Artemis campaign includes conducting more science to better understand planetary processes and evolution, to search for evidence of water and other resources, and support long-term, sustainable human exploration.
The NASA science and technology instruments that launched aboard the IM-2 mission are:
Polar Resources Ice Mining Experiment-1 (PRIME-1): This experiment will explore the Moon’s subsurface and analyze where lunar resources may reside. The experiment’s two key instruments will demonstrate the ability to extract and analyze lunar soil to detect volatile chemical compounds that turn into gas. The two instruments will work in tandem: The Regolith and Ice Drill for Exploring New Terrains will drill into the Moon’s surface to collect samples, while the Mass Spectrometer Observing Lunar Operations will analyze these samples to determine the gas composition released across the sampling depth. The PRIME-1 technology will provide valuable data to better understand the Moon’s surface and how to work with and on it. Laser Retroreflector Array (LRA): This collection of eight retroreflectors will enable precision laser ranging, which is a measurement of the distance between the orbiting or landing spacecraft to the reflector on the lander. The LRA is a passive optical instrument and will function as a permanent location marker on the Moon for decades to come. Micro Nova Hopper: Funded by NASA’s Space Technology Mission Directorate Tipping Point initiative, Intuitive Machines’ Micro Nova hopper, Grace, is designed to enable high-resolution surveying of the lunar surface under its flight path. This autonomous propulsive drone aims to deploy to the surface and hop into a nearby crater to survey the lunar surface and send science data back to the lander. It’s designed to hop in and out of a permanently shadowed region, providing a first look into undiscovered regions that may provide critical information to sustain a human presence on the Moon. Nokia Lunar Surface Communications System (LSCS): Also developed with funding from NASA’s Tipping Point initiative, Nokia’s LSCS 4G/LTE communications system will demonstrate cellular communications between the Intuitive Machines lander, a Lunar Outpost rover, and the Micro Nova hopper. Engineered to transmit high-definition video, command-and-control messages, and sensor and telemetry data, the LSCS aims to demonstrate an ultra-compact advanced communication solution for future infrastructure on the Moon and beyond.
