Approval to Exceed GSA Lodging for LPSC 2026

Approval to Exceed GSA Lodging for LPSC 2026

This letter from SARA is to issue a waiver for NASA grantees attending LPSC2026, allowing them to be reimbursed out of their grants for their actual lodging, although it’s expected to be above the approved GSA amount. This waiver does not supersede the travel policy of your institution if it is more restrictive. Note: I have specified grants (including cooperative agreements). This may also apply to those traveling on NASA contracts, but they should communicate with their contracting officers.

The host hotel for the 57th Lunar and Planetary Science Conference on March 16–20, 2026, is The Woodlands Waterway Marriott Hotel and Convention Center. Hotel information for this conference may be found at https://www.hou.usra.edu/meetings/lpsc2026/plan/

The GSA-allowed daily lodging expense for March 2026 for zip code 77380 (for The Woodlands Waterway Marriott Hotel and Convention Center) is $128 per night. Many of the hotels may be significantly higher than the GSA allowed rate of $128. Grantee travelers may need a waiver to cover lodging in excess of the GSA value, depending on the travel policy of your organization. This waiver does not supersede the travel policy of your institution if it is more restrictive.

By the power vested in me by the NSSC to issue approval of the actual lodging costs for a conference in “bulk” instead of individual approvals, I hereby affirm that for the 57th Lunar and Planetary Science Conference NASA, SMD grants may be charged up to $276/night plus taxes and fees, consistent with the average actual cost of the conference hotel, even though this exceeds the $128 allotted for lodging by GSA for The Woodlands for March 2026.

Thank you

SARA

NASA AI Model That Found 370 Exoplanets Now Digs Into TESS Data

A bright red-orange star burns in the center of the image, with red flames burning off it in all directions. Two dark gray spheres orbit in front of the star, one on the far left (partially in front of the star, partially off the side), and the other at the bottom center.
This artist’s impression shows the star TRAPPIST-1 with two planets transiting across it. ExoMiner++, a recently updated open-source software package developed by NASA, uses artificial intelligence to help find new transiting exoplanets in data collected by NASA’s missions.

Scientists have discovered over 6,000 planets that orbit stars other than our Sun, known as exoplanets. More than half of these planets were discovered thanks to data from NASA’s retired Kepler mission and NASA’s current TESS (Transiting Exoplanet Survey Satellite) mission. However, the enormous treasure trove of data from these missions still contains many yet-to-be-discovered planets. All of the data from both missions is publicly available in NASA archives, and many teams around the world have used that data to find new planets using a number of techniques.

In 2021, a team from NASA’s Ames Research Center in California’s Silicon Valley created ExoMiner, a piece of open-source software that used artificial intelligence (AI) to validate 370 new exoplanets from Kepler data. Now, the team has created a new version of the model trained on both Kepler and TESS data, called ExoMiner++.

The new algorithm, which is discussed in a recent paper published in the Astronomical Journal, identified 7,000 targets as exoplanet candidates from TESS on an initial run. An exoplanet candidate is a signal that is likely to be a planet but requires follow-up observations from additional telescopes to confirm.

ExoMiner++ can be freely downloaded from GitHub, allowing any researcher to use the tool to hunt for planets in TESS’s growing public data archive.

“Open-source software like ExoMiner accelerates scientific discovery,” said Kevin Murphy, NASA’s chief science data officer at NASA Headquarters in Washington. “When researchers freely share the tools they’ve developed, it lets others replicate the results and dig deeper into the data, which is why open data and code are important pillars of gold-standard science.”

ExoMiner++ sifts through observations of possible transits to predict which ones are caused by exoplanets and which ones are caused by other astronomical events, such as eclipsing binary stars. “When you have hundreds of thousands of signals, like in this case, it’s the ideal place to deploy these deep learning technologies,” said Miguel Martinho, a KBR employee at NASA Ames who serves as the co-investigator for ExoMiner++.

This animation shows a graph of the tiny amount of dimming that takes place when a planet passes in front of its host star. NASA’s Kepler and TESS missions spot exoplanets by looking for these transits. ExoMiner++ uses artificial intelligence to help separate real planet transits from other, similar-looking astronomical phenomena.

Kepler and TESS operate differently — TESS is surveying nearly the whole sky, mainly looking for planets transiting nearby stars, while Kepler looked at a small patch of sky more deeply than TESS. Despite these different observing strategies, the two missions produce compatible datasets, allowing ExoMiner++ to train on data from both telescopes and deliver strong results. “With not many resources, we can make a lot of returns,” said Hamed Valizadegan, the project lead for ExoMiner and a KBR employee at NASA Ames.

The next version of ExoMiner++ will improve the usefulness of the model and inform future exoplanet detection efforts. While ExoMiner++ can currently flag planet candidates when given a list of possible transit signals, the team is also working on giving the model the ability to identify the signals themselves from the raw data.

Open-source science and open-source software are why the exoplanet field is advancing as quickly as it is.

In addition to the ongoing stream of data from TESS, future exoplanet-hunting missions will give ExoMiner users plenty more data to work with. NASA’s upcoming Nancy Grace Roman Space Telescope will capture tens of thousands of exoplanet transits — and, like TESS data, Roman data will be freely available in line with NASA’s commitment to Gold Standard Science and sharing data with the public. The advances made with the ExoMiner models could help hunt for exoplanets in Roman data, too.

“The open science initiative out of NASA is going to lead to not just better science, but also better software,” said Jon Jenkins, an exoplanet scientist at NASA Ames. “Open-source science and open-source software are why the exoplanet field is advancing as quickly as it is.”

Snow Buries Kamchatka

Snow Buries Kamchatka

A thick layer of white snow blankets the Kamchatka Peninsula. Layers of clouds surround the peninsula, framing it but leaving its coastlines and a narrow portion of ocean visible around it. On land, several large, circular volcanoes dot the rugged landscape.
January 17, 2026

It has been an eventful few months for the Northern Hemisphere atmosphere. An unusually early sudden stratospheric warming episode in late November appears to have factored into a weakened and distorted polar vortex at times in December, likely causing extra waviness in the polar jet stream. This helped fuel extensive intrusions of frigid air into the mid-latitudes, contributing to cold snaps in North America, Europe, and Asia, and priming the atmosphere for disruptive winter storms in January.

Russia’s Kamchatka Peninsula has been among the areas hit hard by cold and snowy weather in December and January. More than 2 meters (7 feet) of snow fell in the first two weeks of January, following 3.7 meters in December, according to news reports. Together, these totals make it one of the snowiest periods the peninsula has seen since the 1970s, according to Kamchatka’s Hydrometeorology Center. The onslaught brought Petropavlovsk-Kamchatsky, the regional capital, to a standstill, with reports of large snowdrifts burying cars and blocking access to buildings and infrastructure.

This image, acquired by the MODIS (Moderate Resolution Imaging Spectroradiometer) instrument on NASA’s Aqua satellite, shows fresh snow blanketing the peninsula’s rugged terrain on January 17, 2026. Several circular, snow-covered volcanic peaks are visible across the peninsula, one of the most volcanically active areas in the world. Petropavlovsk-Kamchatsky, home to more than 160,000 people, sits along Avacha Bay—a deep, sheltered bay formed by a combination of tectonic, volcanic, and glacial activity.

As America approaches its 250th anniversary of declaring independence, NASA’s Artemis II mission will carry a host of mementos that reflect the nation’s long tradition of exploration, innovation, and leadership in its official flight kit. The items will fly aboard the Orion spacecraft, launched on top of the Space Launch System (SLS) rocket, as it carries four astronauts around the Moon on the first crewed test flight of the agency’s Artemis campaign.

“Historical artifacts flying aboard Artemis II reflect the long arc of American exploration and the generations of innovators who made this moment possible,” said NASA Administrator Jared Isaacman. “This mission will bring together pieces of our earliest achievements in aviation, defining moments from human spaceflight, and symbols of where we’re headed next. During America’s 250th anniversary, Orion will carry astronauts around the Moon while also carrying our history forward into the next chapter beyond Earth.”

Selected to honor America’s historic achievements in space, inspire the next generation of explorers, and reinforce U.S. leadership through international cooperation in science and education, the mementos continue a proud tradition carried forward from Artemis I and earlier human spaceflight missions. Together, they highlight the freedom and innovation that have unlocked the Golden Age of human space exploration.

A 1-inch by-1-inch swatch of muslin fabric from the original Wright Flyer the Wright Brothers used to make the first powered flight in 1903 will be flying aboard Artemis II, lent by the Smithsonian’s National Air and Space Museum. A smaller square cut of the swatch previously flew aboard space shuttle Discovery on STS-51D in 1985 and will make its second journey into space. After the mission, the fabric will be reunited with two other 1903 Wright Flyer swatches at the museum, celebrating the nation’s history and innovation in aviation.

Also flying aboard the Artemis II mission will be a 13-by-8-inch American flag, which flew with the first shuttle mission, STS-1, the final shuttle mission, STS-135, and NASA’s first crewed test flight of SpaceX’s Crew Dragon spacecraft, SpaceX Demo-2.

A flag that was set to fly on NASA’s Apollo 18 mission is included in the flight kit and will make its premiere flight with Orion. The flag serves as a powerful emblem of America’s renewed commitment to human exploration of the Moon, while honoring the legacy of the Apollo pioneers who first blazed the trail.

Orion also will carry a copy of a 4-by-5-inch negative of a photo from the Ranger 7 mission, the first U.S. mission to successfully make contact with the lunar surface. NASA’s Jet Propulsion Laboratory in California managed the Ranger series of spacecraft, built to help identify safe Moon landing sites for Apollo astronauts. The photo represents a major turning point in the race to the Moon that will be echoed today through the success of Artemis.

On Artemis I, a variety of tree seeds flew and were distributed to educational organizations and teachers after the mission, following in the footsteps of tree seeds flown aboard the Apollo 14 mission sprouted into “Moon Trees” after being returned to Earth. The seeds have since taken root at 236 locations across the U.S. to become their own Artemis I Moon Trees. Soil samples collected from the base of established Artemis I Moon Trees planted at NASA’s 10 centers will fly aboard Artemis II, representing the full cycle of exploration: launch, flight, growth, and return to space again. The CSA (Canadian Space Agency) will fly various tree seeds in the kit with the intention of distributing them after the mission.

Also included in the kit will be an SD card including the millions of names of those who participated in the “Send Your Name to Space” campaign, bringing the public along on this journey. The kit will include a variety of flags, patches, and pins to be distributed after the mission to stakeholders and employees who contributed to the flight. 

Additionally, NASA has included items from several of its partners in the kit. Stickers and patches from CSA will fly, and ESA (European Space Agency) will fly a flag in the kit for distribution after the mission, marking NASA’s international collaboration with other space agencies through Artemis. Orion’s European Service Module, the powerhouse of the spacecraft, is provided by ESA.

Carrying mementos on the NASA spacecraft has been a tradition since the 1960s, one that was continued on Artemis I, the first uncrewed test flight of Orion and the SLS. During this mission, Orion carried a symbolic flight kit including historical artifacts, from Apollo missions STEM, or science, technology, engineering, and math, items, digitized student essays and teacher pledges, and more.

The official flight kit for Artemis II, which contains about 10 pounds of mementos in total, augments important scientific research  aboard Orion.

Sound and hearing studies as well as Earth observations kept the Expedition 74 trio busy on Wednesday. The International Space Station residents also worked on cargo transfers, downloaded radiation data, and kept up lab maintenance.

NASA Flight Engineer Chris Williams began his day inside the Columbus laboratory module exploring how sound and shockwaves travel through small, solid particles, also called granular materials. Sensors measured the speed of sound and how the waves weaken and change shape as they move through the loose collection of tiny beads. Results may show how lunar or Martial soils behave as construction materials or during resource extraction. Insights could also lead to a better understanding of soil mechanics on Earth helping prevent landslides and sinkholes.

Williams also took turns with cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev, station Commander and Flight Engineer respectively, taking a regularly scheduled hearing test. Using a quiet area in the orbital outpost, such as the Quest airlock, the crew wore a headset connected to a laptop computer and responded to a series of beeps and tones to check the health of the eardrum and inner ear in microgravity.

Williams spent the second half of his shift organizing cargo inside a SpaceX Dragon spacecraft due to return to Earth this spring. Dragon will bring back a variety completed experiments for analysis including material samples exposed to the external space environment, liquid crystal films developed in microgravity, and stem cells programmed to turn into brain and cardiac cells. Dragon will also fire its engines one more time, while docked to the Harmony module’s forward port, boosting the station’s orbit at the end of the week.

Mikaev continued his Earth observations at the beginning of his shift pointing a camera out windows on the Zvezda and Nauka modules and photographing African landmarks including the Nile Delta, Mount Kilimanjaro, and Lake Malawi. He also performed a monthly collection of radiation detectors and downloaded radiation dosages for review by mission controllers on the ground.

Kud-Sverchkov worked the first half of his shift on electronics and communications maintenance in the Rassvet module. During the second half of his day, the two-time station resident inspected and inventoried electrodes that help maintain muscle health in microgravity then finally replaced expired gas masks with new gas masks inside Nauka.
