Establishing a VTE Risk Score for Astronauts Algorithm

2026-07-17 21:01

In April 2026, NASA’s Office of the Chief Health and Medical Officer (OCHMO) initiated a working group to review updated VTE case information, additional data gathered revealing altered blood flow status within a cohort of astronauts, and discuss progress of research and clinical activities intended to mitigate the risk of VTE during spaceflight with new evidence-based clinical practice recommendations.

Recommendations

The following is a summary of the working group’s recommendations:

  • The working group’s conclusions emphasized that stasis in the left internal jugular vein (IJV) is consistently viewed as a dominant risk factor for VTE in microgravity, though there is active debate regarding the relative contributions of slow qualitative flow, endothelial factors and/or retrograde flow.
  • Limitations of current in-flight ultrasound capabilities to accurately measure stasis/slow flow was cited as a concern, especially if using only stasis as a factor for indicating the need for prophylaxis.
  • Additional review of assessing stasis with ultrasound in-flight was recommended.
  • After reviewing the risk factors, additional discussions following the working group led to the majority of the panel agreeing that stasis and retrograde flow warranted use of prophylaxis.
  • The working group also recommended assessing all other risk factors other than stasis to also determine when prophylaxis is warranted.
  • Based on a literature review and summary of the panel contributions, a VTE Risk Score for Astronauts Algorithm was developed, which includes providing anticoagulation prophylaxis for stasis alone, or a combination of other thrombosis risk factors that are weighted by terrestrial literature.

Risk of Venous Thromboembolism During Spaceflight

NASA initially formed a working group in October 2024 after diagnosing venous thromboembolisms (VTEs) in astronauts during ISS missions. Experts reviewed case data, updated Clinical Practice Guidelines, and examined possible causes.

NASA’s Chandra and IXPE Study Pulsar in Lighthouse Nebula

2026-07-17 20:05

This composite multiwavelength image captures the turbulent environment surrounding the Lighthouse pulsar, set against a vast, black background speckled with twinkling white and faint green stars. In the upper-left quadrant, a massive, cloud-like nebula glows in a textured, vibrant purple hue, anchored by a prominent four-pointed star shining brightly near its center. Moving toward the lower-right quadrant, the pulsar itself is located at the lower tip of a concentrated, brilliant whitish-blue elongated point of light. Extending outward from its core is a long, narrow, and slightly curved jet of purple and blue emission that streaks upward and to the right. This jet represents a massive 37-light-year tail of high-energy particles trailing behind the rapidly spinning star as it plow through interstellar space. This composite image contains X-ray data from NASA's Chandra X-ray Observatory in purple, additional X-ray from NASA's IXPE in blue, and radio data from CSIRO in green. The starfield is optical data from the 2MASS survey.
Scientists using NASA’s IXPE (Imaging X-ray Polarimetry Explorer) directly measured the magnetic fields of PSR J1101−6101, a pulsar located within what is often referred to as the “Lighthouse” Nebula, for the first time.

This composite image, released on July 9, 2026, shows the region around a pulsar – a neutron star with a strong magnetic field that spins incredibly fast – within the Lighthouse nebula. The image contains X-ray data from NASA’s Chandra X-ray Observatory in purple, X-rays from NASA’s IXPE (Imaging X-ray Polarimetry Explorer) in blue, and radio emission captured by the Australia Compact Telescope Array in green.

Scientists used IXPE – for the first time ever – to directly measure the magnetic fields of the pulsar. The results provide new insight into the structure of some of the most extreme objects in the cosmos, as NASA continues to explore the secrets of how the universe works. A paper describing the results published July 9 in the Astrophysical Journal.

Media accreditation now is open for the launch of NASA’s Nancy Grace Roman Space Telescope and the agency’s SpaceX Crew-13 missions, both targeting launch in the coming months.

The Roman telescope is slated to launch no earlier than 7:20 a.m. EDT Sunday, Aug. 30, aboard a SpaceX Falcon Heavy rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. The observatory, named after NASA’s first chief astronomer, will have a deep, panoramic view of the cosmos, generating never-before-seen pictures that will revolutionize our understanding of the universe.

NASA’s Nancy Grace Roman Space Telescope is seen here in the clean room at the agency’s Goddard Space Flight Center in Greenbelt, Maryland, where the observatory was built and tested. Roman’s vast, deep surveys will explore dark matter, dark energy, exoplanets, and almost anything from our own solar system to galaxies at the edge of the observable universe.

Crew-13 is scheduled to launch no earlier than mid-September from Space Launch Complex 40 at Cape Canaveral Space Force Station. The mission will carry NASA astronauts Jessica Watkins and Luke Delaney, CSA (Canadian Space Agency) astronaut Joshua Kutryk, and Roscosmos cosmonaut Sergey Teteryatnikov to the International Space Station for a science and research expedition. This will be NASA’s 13th commercial crew rotation mission with SpaceX’s Falcon 9 rocket and Dragon spacecraft.
