A giant 10-sided wave is emerging around Saturn’s south pole, giving scientists a rare chance to watch a planetary weather pattern take shape. NASA’s Hubble Space Telescope has detected a huge, evolving atmospheric wave with 10 sides wrapped around Saturn’s south pole. It is the first time scientists have seen a large, regular-sided jet pattern [...]The NSSC provides travel reimbursement services for all authorized Agency travel including: domestic, foreign, local, ETDY, and Change of Station (COS).

NASA Domestic Travel: Day that Travel Ends
For the day travel ends (the day a traveler returns to the PDS, home, or other authorized point), the per diem allowance is 75% of M&IE.
NASA Domestic Travel Rental Car Liability
When making a reservation for a rental car, please remember the Government is only responsible to pay for rental car charges for official travel time. If a traveler decides to take annual leave in conjunction with official travel and keeps the rental car during annual leave, the portion of the rental rate applicable to annual leave is the responsibility of the traveler. Please refer to 41 CFR 301-10.453
What is my liability for unauthorized use of a rental automobile obtained with Government funds?
You are responsible for any additional cost resulting from the unauthorized use of a commercial rental automobile for other than official travel-related purposes.
NASA Domestic Travel: Tax Exemption
Prior to traveling, refer to the GSA State Tax Information webpage: https://smartpay.gsa.gov/smarttax. Select your State/US territory of interest to see the exemption status and download the appropriate form, if required.
Reduced Per Diem rate
NASA’s standard reduced per diem rate for ETDY travel is 65 percent under the current policy as defined in the NASA Procedural Requirements (NPR) 9750.1-3.1.2.
a. Consistent with 41 CFR 301-11.200, an ETDY authorization can include reasonable further reductions from this standard rate or limitations on approved lodging for unique circumstances, to the extent it can be determined in advance that such will substantially lower costs without mission impact. For example, if lodging is obtained at 50 percent per diem, the ETDY authorization should be adjusted to authorize a lower rate.
b. The reduced rate of reimbursement begins on the first day of travel regardless of the mode of transportation, except as noted in 3.1.3. Allowances are covered by the reduced per diem rate; therefore, NASA will authorize the employee a per diem rate (up to 65 percent) to reasonably cover expenses for a one bedroom furnished apartment. For ETDY greater than 90 days, first consideration should be given to long-term lodging facilities. Long-term lodging facilities are available on the GSA schedule at http://www.gsa.gov. If a long-term facility is not selected, proper justification should be provided.
Find more about Allowable ETDY Expenses Included in Reduced Per Diem Rate, please see the following document:
Allowable ETDY Expenses Included in Reduced Per Diem Rate
GSA Long-term Lodging (Schedule 48)
GSA’s Schedule 48 is designed for lodging needs of 30 days or more. This program provides housing accommodations for temporary or permanent relocation. Typical facilities include apartment or condominium type properties that may be furnished with all the amenities of a regular home. The current list of vendors is available by clicking on the link above. Most of these properties will accommodate NASA Extended TDY travelers within the 65% reduce per diem rate and will allow use of the government charge card.
Please consult the Code of Federal Regulations (CFR), NPR 9710.1, and NPR 9750.1. Please call the NSSC Contact Center using this form for additional information.
In August 2026, a series of powerful winter storms transformed parts of northern Chile’s Atacama Desert, covering the famously dry landscape in an unusual layer of snow. Snow is not unheard of in the Atacama. Significant falls occurred in 2025 and, before that, in 2011. But one of the August 2026 storms stood out because [...]Puerto Rico went from no drought to widespread extreme drought in just months as rainfall collapsed and water shortages spread. Puerto Rico usually enters its wet season in May. In 2026, however, the expected rains largely failed to arrive through late August, leaving much of the U.S. territory in drought. The prolonged dry spell has [...]A giant 29-square-mile iceberg broke from Greenland’s Petermann Glacier and survived a collision with Joe Island that might have shattered a more fragile berg. Summer is the busiest time of year for iceberg activity in Greenland’s glacier-fed fjords, and 2026 brought another dramatic example. In August, a huge iceberg separated from Petermann Glacier on Greenland’s [...]New Mexico’s largest reservoir plunged to just 1.4 percent capacity in July 2026, revealing the dramatic impact of prolonged drought and record early snowmelt. NASA is using satellite data to help water managers understand the shrinking supply and prepare for future shortages. When astronaut John Glenn remarked on the landscape below him while orbiting Earth [...]NASA’s Neil Gehrels Swift Observatory is back to studying the universe, even as the aging spacecraft continues to lose altitude and a planned mission to raise its orbit has been scaled back. Two of Swift’s three science instruments are operating again after months of conservation measures designed to reduce atmospheric drag and keep the observatory [...]Webb found a hidden giant planet by detecting its atmospheric chemistry through a bright debris disk. For years, a third giant planet remained concealed within the bright dust surrounding Beta Pictoris, one of the most closely observed planetary systems in the Milky Way. NASA’s James Webb Space Telescope has now exposed the hidden world by [...]

NASA is teaming up with 37 companies to develop the next generation of technologies that could make long-term exploration of the Moon and Mars possible. NASA has chosen 41 proposals from 37 U.S. companies to help develop technologies needed for a sustained human presence on the Moon and eventual crewed missions to Mars. The companies [...]NASA is taking another major step toward a permanent Moon base with four new commercial missions that will test technology, deliver science, and help prepare for humanity’s future beyond Earth. NASA has selected three commercial space companies to carry out four new lunar missions in late 2028 through the agency’s Moon Base Program. Astrobotic, Firefly [...]A new NASA orbital image captures Perseverance after completing a marathon across the surface of Mars. NASA’s Perseverance rover has completed the equivalent of a full marathon on Mars, reaching 26.2 miles (42.195 kilometers) after five years and four months of driving across the Red Planet. The milestone came on the 1,890th Martian day, or [...]Nature, Published online: 08 July 2026; doi:10.1038/s41586-026-10725-y

NASA’s newly announced Artemis III crew is preparing for one of the most complex space missions ever attempted on the road back to the Moon. NASA has unveiled the crew for Artemis III and shared new details about what could become one of the most challenging human spaceflight missions ever attempted. Scheduled for 2027, the [...]Sentinel-6 satellite data shows strengthening warm-water waves in the Pacific, pointing to the likely arrival of El Niño and its global weather impacts later in 2026. Several months before an El Niño develops, large waves of warmer, elevated water travel eastward across the Pacific Ocean. Satellite observations in 2026 have detected several of these waves. [...]NASA just demonstrated a technology that lets spacecraft communicate across multiple networks, paving the way for a more flexible and reliable space internet. NASA’s experimental Polylingual Experimental Terminal (PExT) has successfully completed its primary technology demonstration, marking an important step toward more flexible communications in space. Because the project met its original goals and continues [...]NASA has released a new update on a long-running air leak aboard the International Space Station, detailing recent developments involving a troubled section of the orbiting laboratory and precautionary measures taken to protect the crew. The issue involves the PrK transfer tunnel inside Russia’s Zvezda service module, where cracks have been causing small atmosphere leaks [...]
