NASA’s Psyche spacecraft has now successfully completed its close flyby of Mars on the 15th of May 2026, coming within about 2,864 miles (~4,609 kilometers) of the planet’s surface. The Mars flyby was carried out in order to use the Red Planet’s gravity as a boost mechanism so as to increase the spacecraft’s speed and also alter its orbital plane without making use of onboard propellant. Following the maneuver, the spacecraft is now confirmed to be on the correct trajectory toward the metal-rich 16 Psyche asteroid located between Mars and Jupiter in the main asteroid belt.

Here’s more about it.

NASA’s Psyche Spacecraft Successfully Completes Mars Flyby

After the successful flyby maneuver, NASA’s flight team analyzed radio signals exchanged between the spacecraft and the agency’s NASA Deep Space Network so as to verify that the spacecraft was moving along the planned trajectory. As per Don Han – Psyche’s navigation lead at Jet Propulsion Laboratory, the Mars gravity assist has now provided the spacecraft with a speed boost of around 1,000 miles per hour while also shifting its orbital plane by nearly one degree relative to the Sun. With this, the spacecraft is now expected to arrive at asteroid Psyche in the summer season of 2029.

Ahead of and during the close approach, all scientific instruments onboard the spacecraft were powered up as part of various calibration activities. This included the imagers, magnetometers, and gamma-ray and neutron spectrometer instruments. The Mars encounter also offered a valuable testing opportunity for the mission team before the spacecraft eventually reaches asteroid Psyche. In addition to this, the spacecraft was also able to capture unique images of Mars from a rare viewing angle.

Because the spacecraft approached Mars from a high phase angle, the planet appeared as a thin crescent illuminated by sunlight reflected from its surface. Observations captured using the spacecraft’s multispectral imaging system revealed that the crescent appeared brighter and stretched farther across the planet’s disk than initially expected due to the scattering of sunlight through Mars’ dusty atmosphere. Around the moment of closest approach, the spacecraft also captured a rapid sequence of surface images while transitioning from the nighttime side of Mars toward daylight.

Jim Bell – the Psyche imager instrument lead at Arizona State University, also revealed that thousands of images of Mars and its atmosphere had been captured during the flyby process. As per him, the collected data will help the mission team calibrate the spacecraft cameras and improve image processing tools that are currently being developed for use once the spacecraft reaches asteroid Psyche.

It has also been revealed that several other Mars missions contributed complementary imaging and navigation data during the flyby. These include NASA’s Perseverance rover mission, Mars Reconnaissance Orbiter, 2001 Mars Odyssey, Curiosity rover, along with the European Space Agency missions Mars Express and ExoMars Trace Gas Orbiter.

With Mars now behind it, the spacecraft is expected to resume its solar-electric propulsion journey toward the asteroid belt. Upon arrival in August 2029, the spacecraft will enter orbit around asteroid Psyche, which scientists currently believe could be the exposed metallic core of an ancient planetesimal. Through multiple orbital phases at varying altitudes, the spacecraft will map the asteroid and gather scientific data in detail. If confirmed to be a metallic planetary core, the asteroid may provide researchers with valuable insight into the interiors of rocky planets such as Earth.

Stay tuned for more updates.

The newest investigation will explore how living in microgravity affects blood-making cells, or blood platelets, at the cellular and genetic level. Researchers will observe the cells growing into platelets to understand how weightlessness affects a crew member’s blood clotting and immune function.

Observations from the experiments are said to expand the knowledge of space phenomena and inspire junior high and high school students to consider scientific, technical and engineering careers.

Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergey Mikaev have also collected their blood pressure measurements, helping doctors understand how weightlessness affects a crew member’s blood vessels.

The Expedition 74 Crew explored advanced treatments for cancer and cartilage injuries using the weightless environment to gain new biomedical insights.

NASA flight engineer Chris Williams set up the cancer research hardware inside one of the Kibo laboratory module’s research racks to begin observing microgravity’s effect on an anti-cancer drug and its molecular mechanisms. Results may lead to the development of more effective therapies to treat pancreatic cancer both on  Earth and in microgravity.

NASA flight engineer Jessica Meir is exploring ways to grow cartilage tissue in space using specialised hardware to form more natural structures. Meir processed and preserved cartilage samples—grown on Earth and launched aboard Dragon—inside Kibo’s Life Science Glovebox. The tissue samples will be incubated inside the Space Automated Bioproduct Laboratory to learn how to improve cartilage tissue engineering methods in weightlessness. Insights may provide new fitness regimens to protect astronaut health and promote the development of advanced implants to repair and regenerate injured cartilage in patients on Earth.

The flight will be the 12^th overall for Starship but the first of the bigger and more powerful “Version 3” (V3) iteration of the vehicle.

The Starship spacecraft of SpaceX, as already known, is the largest and most powerful rocket made by humanity, and its primary goal is to help in colonising Mars. It stands 122 meters tall, and is made out of stainless steel with two major parts: the upper stage spacecraft – ‘Spaceship’ or simply referred to as the ‘Ship’, and the booster that is called ‘Super Heavy’.

It is said that Starship will be able to carry up to 100 people on long-duration, interplanetary flights. It will also help enable satellite delivery, the development of a Moon base, and point-to-point transport here on Earth.

Reportedly, Starship has 11 suborbital test flights under its belt, five of which occurred last year. Last year, Musk also announced that Starship will depart for Mars carrying Optimus at the end of 2026, and if those landings go well, then human landings may start as soon as 2029, although 2031 is more likely.

A few days back, four crew members of NASA’s SpaceX Crew-12 mission launched from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida for a science expedition aboard the International Space Station. A SpaceX Falcon 9 rocket propelled a Dragon spacecraft into orbit carrying NASA astronauts.

On February 14, NASA updated that the astronauts had arrived at the International Space Station as the SpaceX Dragon spacecraft docked with the orbiting complex. Later, it was revealed that NASA astronauts Jessica Meir and Jack Hathaway, ESA (European Space Agency) astronaut Sophie Adenot, and Roscosmos cosmonaut Andrey Fedyaev had entered the International Space Station after opening the hatches between the space station and the SpaceX Dragon spacecraft.

These members have now joined the Expedition 74 crew, including NASA astronaut Chris Williams and Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev already aboard the orbiting laboratory.

It was revealed that during its mission, Crew-12 will conduct scientific research to prepare for human exploration beyond low Earth orbit and to benefit humanity on Earth. Participating crew members will study pneumonia-causing bacteria to improve cardiovascular treatments, on-demand intravenous fluid generation for future space missions, and research on how physical characteristics may affect blood flow during spaceflight.

Other experiments include automated plant health monitoring and investigations of plant and nitrogen-fixing microbe interactions to enhance food production in space.

This Crew-12 mission is part of NASA’s Commercial Crew Program, which provides reliable access to space, maximising the use of the station for research and development, and supporting future missions beyond low Earth Orbit by partnering with private companies to transport astronauts to and from the International Space Station.

Space Situational Awareness System- Stargaze

According to the company, practices such as leaving rocket bodies in low Earth orbit, operators maneuvering their satellites without sharing trajectory predictions or coordinating with other active satellites, and countries conducting anti-satellite tests have heightened the risk of collisions, increasing the need for improvements in space-traffic coordination.

To work on this issue, Stargaze delivers a several-order-of-magnitude increase in detection capability compared to conventional ground-based systems. This system is said to use data collected from nearly 30,000 star trackers, each of which makes continuous observations of nearby objects, resulting in approximately 30 million transits detected daily across the fleet.

SpaceX has developed this system to provide conjunction screening results within minutes, compared to the current industry standard of several hours.

It is revealed that in late 2025, a Starlink satellite encountered a conjunction with a third-party satellite that was performing maneuvers, but whose operator was not sharing ephemeris. Until five hours before the conjunction, the close approach was anticipated to be ~9,000 meters—considered a safe miss-distance with zero probability of collision. With just five hours to go, the third-party satellite performed a manoeuvre that changed its trajectory and collapsed the anticipated miss distance to just ~60 meters. Stargaze quickly detected this maneuver and published an updated trajectory to the screening platform, generating new CDMs which were immediately distributed to relevant satellites. Ultimately, the Starlink satellite was able to react within an hour of the maneuver being detected, planning an avoidance maneuver to reduce collision risk back down to zero.

The company has mentioned that the Starlink ephemeris is updated and shared publicly every hour, and all other operators should do the same.

Availability

SpaceX will be making Stargaze conjunction data available to all operators, free of charge, via its space-traffic management system. This platform has been in a closed beta with over a dozen participating satellite operators, allowing low-latency ephemeris sharing and conjunction screening.

Starting this Spring, operators that submit ephemeris (trajectory predictions) to the platform will also receive Conjunction Data Messages (CDMs) against Stargaze data, in addition to ephemeris from other participating operators.

After the injection of EOS-N1 and 14 satellites, the PS4 stage was supposed to be restarted to de-boost and enter a re-entry trajectory, followed by KID capsule separation. This was a commercial mission undertaken by NewSpace India Limited (NSIL).

Well, ISRO’s first mission of 2026 has now faced a hurdle as it is revealed that the PSLV-C62 mission encountered an anomaly during the end of the PS3 stage, causing it to deviate from its flight path. ISRO has initiated a detailed analysis to find the root cause of this setback.

The PSLV is a four-stage vehicle with two solid stages and two liquid stages. It is revealed that the first two stages were completed successfully, but close to the end of the third stage (PS3), there was a disturbance seen in the vehicle roll rates, and then there was a deviation observed in the flight path.

The primary objective of this mission was to deploy satellites into a Sun-Synchronous Orbit at an altitude of approximately 511km. Scientists are now going through telemetry data to understand why the roll rates fluctuated, preventing the PSLV-C62 from achieving its objective.

NASA made an announcement on January 7th that it has postponed a scheduled spacewalk that was planned to take place on Thursday, January 8, outside the International Space Station. The decision followed a medical concern involving a crew member aboard the orbital laboratory.

In an official update, NASA confirmed that the medical situation arose on Wednesday afternoon. While the agency did not disclose further details, citing medical privacy, it stated that the affected crew member is stable. NASA added that it continues to monitor the situation closely.

“The situation is stable,” the agency said, noting that additional details — including a revised date for the postponed spacewalk — will be shared at a later time.

Further clarification was provided in a subsequent International Space Station status update. NASA confirmed that the medical matter involved a single crew member and reiterated that crew safety remains its highest priority. The agency also stated that it is actively evaluating all available options, including the possibility of an earlier-than-planned conclusion to the Crew-11 mission if required.

“These are the situations NASA and our partners train for and prepare to execute safely,” the agency said, adding that further updates will be issued within the next 24 hours.

The Crew-11 team currently aboard the ISS consists of American astronauts Zena Cardman and Mike Fincke, Japan Aerospace Exploration Agency (JAXA) astronaut Kimiya Yui, and Roscosmos cosmonaut Oleg Platonov.

The four-member crew launched to the International Space Station on August 1, 2025. Their mission was originally scheduled to conclude in late February 2026, following the arrival of a replacement crew.

NASA has not indicated whether the medical situation will impact the overall mission timeline, beyond confirming that all operational decisions will be guided by crew health and safety considerations.

Thanks to the ongoing Experimental Advanced Superconducting Tokamak (EAST) experimental project, which is also being called as China’s Artificial Sun experiment, researchers have been able to identify a way to surpass the plasma density limit. Notably, the results of this experiment have provided a crucial physical basis for the high density operation in magnetic confinement fusion devices.

Read more about it below.

Chinese Researchers Find a Way to Surpass the Plasma Density Limit

The Experimental Advanced Superconducting Tokamak (EAST) or the Artificial Sun experiment is being conducted under the collaborative efforts from the Chinese Academy of Sciences (CAS), Huazhong University of Science and Technology (HUST), Aix-Marseille University (amU) in France, and more at the Institute of Plasma Physics, Hefei Institutes of Physical Sciences, and researchers associated with this experimental project has found a way to surpass the plasma density limit.

Speaking more, the tokamak that resembles a helical-shaped magnetic racetrack, is a toroidal device which makes use of magnetic confinement in order to achieve controlled nuclear fusion, and plasma density is considered to be a crucial factor that affects the performance of the tokamak. Researchers have already identified that there is an upper limit for the plasma density, and once it hits this limit, the plasma escapes the magnetic confinement by becoming unstable. Additionally, it has also been understood with long-term research that the physical reasons triggering the plasma density limit occur at the plasma-wall boundary region, however the reasons to why this happens have remained unclear until recently.

A self-organized plasma-wall interaction theoretical model has been developed by the Chinese researchers, and they have identified the critical role of radiation instability. With the help of this insight, researchers were able to surpass the plasma density limit, bringing it to a density-free zone, thus providing a confirmation of this zone in tokamaks.
