SpaceX is set to launch Fram2 on Monday, March 31, at 9:46 p.m. ET from Launch Complex 39A at NASAâs Kennedy Space Center. If needed, additional opportunities extend through the early hours of April 1. This mission is unlike any beforeâit will take humanity to a polar orbit (90° inclination) for the first time! đâš
đ°ïž What Makes Fram2 Special?
đ„ First-ever human spaceflight to a true polar orbit.
đšâđ All four astronautsâWang, Mikkelsen, Rogge, and Philipsâare first-time space travelers.
đ©» First medical X-ray taken in space.
đ Microgravity experiments, including mushroom cultivation.
đȘ Independent crew exit post-splashdownâpushing the limits of astronaut endurance.
đ Falcon 9 and Dragonâs Role.
This mission will push the boundaries of Falcon 9 and Dragonâs ascent profile, showcasing the precision and power of SpaceXâs GNC (Guidance, Navigation, and Control) systems. After liftoff, the first stage booster will return to the droneship A Shortfall of Gravitas in the Atlantic Ocean. The Dragon capsule has a rich history, having previously flown on Crew-1, Inspiration4, and Polaris Dawn.
Fram2 is more than just a missionâitâs a bold step toward the future of space exploration. With 22 research experiments, including studies on human health in space, exercise physiology, and radiation exposure, this flight will pave the way for long-duration missions beyond Earth orbit.

Without the ability to control infrared light waves, autonomous vehicles wouldnât be able to quickly map their environment and keep âeyesâ on the cars and pedestrians around them; augmented reality couldnât display realistic 3D displays; doctors would lose an important tool for early cancer detection. Dynamic light control allows for upgrades to many existing systems, but complexities associated with fabricating programmable thermal devices hinder availability.
A new active metasurface, the electrically-programmable graphene field effect transistor (Gr-FET), from the labs of Sheng Shen and Xu Zhang in Carnegie Mellon Universityâs College of Engineering, enables the control of mid-infrared states across a wide range of wavelengths, directions, and polarizations. This enhanced control enables advancements in applications ranging from infrared camouflage to personalized health monitoring.
âFor the first time, our active metasurface devices exhibited the monolithic integration of the rapidly modulated temperature, addressable pixelated imaging, and resonant infrared spectrum,â said Xiu Liu, postdoctoral associate in mechanical engineering and lead author of the paper published in Nature Communications. âThis breakthrough will be of great interest to a wide range of infrared photonics, materials science, biophysics, and thermal engineering audiences.â
The last time a new class of antibiotics reached the market was nearly three decades agoâbut that could soon change, thanks to a discovery by researchers at McMaster University.
A team led by researcher Gerry Wright has identified a strong candidate to challenge even some of the most drug-resistant bacteria on the planet: a new molecule called lariocidin. The findings were published in the journal Nature on March 26, 2025.
The discovery of the all-new class of antibiotics responds to a critical need for new antimicrobial medicines, as bacteria and other microorganisms evolve new ways to withstand existing drugs. This phenomenon is called antimicrobial resistanceâor AMRâand itâs one of the top global public health threats, according to the World Health Organization.
Leveraging Preexisting Cardiovascular Data to Improve the Detection and Treatment of Hypertension: The NOTIFY-LVH Randomized Clinical Trial

From JAMA Cardiol ogy: A centralized, population health coordinator-led notification and clinical support pathway improved the initiation of antihypertensive therapy in patients with left ventricular hypertrophy.
Despite the recognition that poorly controlled hypertension leads to adverse cardiovascular events, there are often barriers in care systems that contribute to substandard recognition and treatment.19 Notably, prior work employing trained nonphysicians focused on closing gaps in cardiovascular disease management has yielded significant improvements in disease-specific metrics using remote, centralized interventions.20-25 Similarly, there is a growing body of evidence demonstrating the effectiveness of clinician-directed support systemsâoften in the form of ânudgesââthat have made meaningful advances in a variety of clinical outcomes.26,27 Whether a methodologic approach combining clinician nudges with the support of trained nonphysicians can be applied to LVH-associated diseasesâincluding hypertensionâis unknown.
Accordingly, the NOTIFY-LVH pragmatic randomized clinical trial28 sought to determine whether potentially underutilized echocardiogram data could be leveraged to improve patient care by augmenting the traditional ambulatory care framework. Specifically, this study tested whether a centralized clinical support pathway targeting clinicians of patients with LVH on their prior echocardiograms would increase the rate of treatment for hypertension and the earlier diagnosis of LVH-associated diseases.
Cases of the fungal infection Candida auris are rising rapidly and coming from more sources too, a new US study reveals.
C. auris was first reported in the US in 2016 and is considered an âurgent antimicrobial resistance threatâ in hospitals, according to the Centers for Disease Control and Prevention (CDC).
Focusing on a large health system in Miami, Florida, the new research found that reported clinical cases had risen from 5 in 2019 to 115 in 2023 â a considerable jump of 2,200 percent in four years.
NASAâs BioNutrients series of experiments is testing ways to use microorganisms to make nutrients that will be needed for human health during future long-duration deep space exploration missions.
Some vital nutrients lack the shelf-life needed to span multi-year human missions, such as a mission to Mars, and may need to be produced in space to support astronaut health. To meet this need, the BioNutrients project uses a biomanufacturing approach similar to making familiar fermented foods, such as yogurt. But these foods will also include specific types and amounts of nutrients that crews will be able to consume in the future.
The first experiment in the series, BioNutrients-1, set out to assess the five-year stability and performance of a hand-held systemâcalled a production packâthat uses an engineered microorganism, yeast, to manufacture fresh vitamins on-demand and in space.

Many Americans are deficient in vitamin D, vitamin B12 and omega-3 fatty acids, all of which affect energy levels.
