Credit: NASA NASA has selected SpaceX of Starbase, Texas, to provide launch services for the Near-Earth Object (NEO) Surveyor mission, which will detect and observe asteroids and comets that could potentially pose an impact threat to Earth.
The firm fixed price launch service task order is being awarded under the indefinite delivery/indefinite quantity NASA Launch Services II contract. The total cost to NASA for the launch service is approximately $100 million, which includes the launch service and other mission related costs. The NEO Surveyor mission is targeted to launch no earlier than September 2027 on a SpaceX Falcon 9 rocket from Florida.
The NEO Surveyor mission consists of a single scientific instrument: an almost 20-inch (50-centimeter) diameter telescope that will operate in two heat-sensing infrared wavelengths. It will be capable of detecting both bright and dark asteroids, the latter being the most difficult type to find with existing assets. The space telescope is designed to help advance NASA’s planetary defense efforts to discover and characterize most of the potentially hazardous asteroids and comets that come within 30 million miles of Earth’s orbit. These are collectively known as near-Earth objects, or NEOs.
The mission will carry out a five-year baseline survey to find at least two-thirds of the unknown NEOs larger than 140 meters (460 feet). These are the objects large enough to cause major regional damage in the event of an Earth impact. By using two heat-sensitive infrared imaging channels, the telescope can also make more accurate measurements of the sizes of NEOs and gain information about their composition, shapes, rotational states, and orbits.
The mission is tasked by NASA’s Planetary Science Division within the agency’s Science Mission Directorate at NASA Headquarters in Washington. Program oversight is provided by NASA’s Planetary Defense Coordination Office, which was established in 2016 to manage the agency’s ongoing efforts in planetary defense. NASA’s Planetary Missions Program Office at the agency’s Marshall Space Flight Center in Huntsville, Alabama, provides program management for NEO Surveyor. The project is being developed by NASA’s Jet Propulsion Laboratory in Southern California.
Multiple aerospace and engineering companies are contracted to build the spacecraft and its instrumentation, including BAE Systems SMS (Space & Mission Systems), Space Dynamics Laboratory, and Teledyne. The Laboratory for Atmospheric and Space Physics at the University of Colorado, Boulder, will support operations, and the Infrared Processing and Analysis Center at the California Institute of Technology (Caltech) in Pasadena, California, is responsible for processing survey data and producing the mission’s data products. Caltech manages JPL for NASA. Mission team leadership includes the University of California, Los Angeles. NASA’s Launch Services Program at the agency’s Kennedy Space Center in Florida is responsible for managing the launch service.

4 Min Read Heart Health

February was first proclaimed as American Heart Month in 1964. Since then, its 28 (or 29) days have served as an opportunity to encourage people to focus on their cardiovascular health.
The International Space Station serves as a platform for a variety of ongoing research on human health, including how different body systems adapt to weightlessness. This research includes assessing cardiovascular health in astronauts during and after spaceflight and other studies using models of the cardiovascular system, such as tissue cultures. The goal of this work is to help promote heart health for humans in space and everyone on Earth. For this Heart Month, here is a look at some of this spaceflight research
Building a better heart model
Media exchange in the tissue chambers for the Engineered Heart Tissue investigation.NASA Microgravity exposure is known to cause changes in cardiovascular function. Engineered Heart Tissues assessed these changes using 3D cultured cardiac tissues that model the behavior of actual heart tissues better than traditional cell cultures. When exposed to weightlessness, these “heart-on-a-chip” cells behaved in a manner similar to aging on Earth. This finding suggests that these engineered tissues can be used to investigate the effects of space radiation and long-duration spaceflight on cardiac function. Engineered tissues also could support development of measures to help protect crew members during a mission to Mars. Advanced 3D culture methodology may inform development of strategies to prevent and treat cardiac diseases on Earth as well.
Private astronaut heart health
In April 2022, the 11-person station crew included (clockwise on the outside from bottom right) NASA astronaut Tom Marshburn; Roscomos cosmonauts Oleg Artemyev, Denis Matveev, and Sergey Korsakov; NASA astronauts Raja Chari, Kayla Barron, and Matthias Maurer; and Ax-1 astronauts (center row from left) Mark Pathy, Eytan Stibbe, Larry Conner, and Michael López-Alegría.-Alegria.NASA For decades, human research in space has focused on professional and government-agency astronauts, but commercial spaceflight opportunities now allow more people to participate in microgravity research. Cardioprotection Ax-1 analyzed cardiovascular and general health in private astronauts on the 17-day Axiom-1 mission.
The study found that 14 health biomarkers related to cardiac, liver, and kidney health remained within normal ranges during the mission, suggesting that spaceflight did not significantly affect the health of the astronaut subjects. This study paves the way for monitoring and studying the effects of spaceflight on private astronauts and developing health management plans for commercial space providers.
Better measurements for better health
ESA astronaut Tim Peake conducts operations for the Vascular Echo experiment. NASA Vascular Echo, an investigation from CSA (Canadian Space Agency), examined blood vessels and the heart using a variety of tools, including ultrasound. A published study suggests that 3D imaging technology might better measure cardiac and vascular anatomy than the 2D system routinely used on the space station. The research team also developed a probe for the ultrasound device that better directs the beam, making it possible for someone who is not an expert in sonography to take precise measurements. This technology could help astronauts monitor heart health and treat cardiovascular issues on a long-duration mission to the Moon or Mars. The technology also could help patients on Earth who live in remote locations, where an ultrasound operator may not always be available.
Long-term heart health in space
As part of exploring ways to keep astronauts healthy on missions to the Moon and Mars, NASA is conducting a suite of space station studies called CIPHER that looks at the effects of spaceflight lasting up to a year. One CIPHER study, Vascular Calcium, examines whether calcium lost from bone during spaceflight might deposit in the arteries, increasing vessel stiffness and contributing to increased risk of future cardiovascular disease. Astronaut volunteers provide blood and urine samples and undergo ultrasound and high-resolution scans of their bones and arteries for this investigation. Another CIPHER study, Coronary Responses, uses advanced imaging tests to measure heart and artery response to spaceflight.
These studies will help scientists determine whether spaceflight accelerates narrowing and stiffening of the arteries, known as atherosclerosis, or increases the risk of atrial fibrillation, a rapid and irregular heartbeat seen in middle-aged adults. This work also could help identify potential biomarkers and early warning indicators of cardiovascular disease.
