NASA has announced that astronaut Nick Hague and Roscosmos cosmonaut Aleksandr Gorbunov will be launching on the SpaceX Crew-9 mission to the International Space Station (ISS) no earlier than Tuesday, September 24, 2024. This update comes after changes to the mission’s crew composition. Originally, NASA astronauts Zena Cardman and Stephanie Wilson were also part of the Crew-9 team, but they are now eligible for reassignment to future missions.

Updated Crew and Mission Adjustments

The upcoming SpaceX Crew-9 mission will now be flown with a two-person crew aboard a SpaceX Dragon spacecraft. Nick Hague will serve as the mission commander, while Aleksandr Gorbunov will take on the role of mission specialist. This adjustment follows NASA’s decision to return the agency’s Boeing Crew Flight Test uncrewed, resulting in two vacant seats on Crew-9. NASA’s decision was made by Joe Acaba, Chief Astronaut at NASA’s Johnson Space Center, who needed to ensure a balanced crew with essential experience and integration for the mission.

Joe Acaba explained that the decision to reduce the crew size was challenging. The crew had trained as a team of four, and adjusting to a smaller crew presented its own set of difficulties. Despite this, Acaba expressed confidence in the crew’s capabilities, noting that Zena Cardman and Stephanie Wilson would continue to support their colleagues in preparation for the mission. Both Cardman and Wilson remain committed to the mission‘s success and look forward to participating in future spaceflights.

Crew Profiles and Upcoming Mission

Nick Hague is set to undertake his third spaceflight. His previous missions include a challenging launch in October 2018, which involved an emergency landing following a rocket failure, and a subsequent successful mission in March 2019. During his time on the ISS, Hague conducted three spacewalks focused on upgrading the space station’s power systems and installing a docking adapter for commercial spacecraft. Hague, an active-duty Colonel in the U.S. Space Force, will be returning to NASA after contributing to the Boeing Starliner Programme.

Aleksandr Gorbunov will be embarking on his first space mission. Gorbunov, a native of Zheleznogorsk, Russia, has a background in spacecraft engineering and aircraft maintenance from his studies at the Moscow Aviation Institute and his work with Rocket Space Corp. Energia. His experience includes supporting cargo spacecraft launches from the Baikonur Cosmodrome before his selection as a cosmonaut in 2018.

Once in space, Hague and Gorbunov will join Expedition 72 aboard the ISS. They will work alongside Butch Wilmore, Suni Williams, NASA astronaut Don Pettit, and Roscosmos cosmonauts Alexey Ovchinin and Ivan Vagner. Their mission will focus on scientific research and maintenance as the ISS continues its 24-year history of continuous human habitation.

SpaceX Successfully Deploys 21 Starlink Satellites, Loses Falcon 9 Booster

SpaceX Successfully Deploys 21 Starlink Satellites, Loses Falcon 9 Booster

A Falcon 9 rocket carrying 21 Starlink satellites was launched by SpaceX from Cape Canaveral Space Force Station on March 2. Liftoff took place at 9:24 p.m. ET on March 3, with the mission including 13 satellites equipped with direct-to-cell capabilities. The first stage of the rocket successfully landed on the droneship “Just Read the Instructions” stationed approximately 400 kilometres off Florida’s coast. However, the booster, designated B1086, was lost shortly after landing due to damage sustained by one of its landing legs.

Booster Loss After Landing

According to SpaceX, a fire at the aft end of the booster resulted in structural damage, leading to its collapse. The incident occurred after the rocket had completed its return to Earth and made contact with the landing platform. Data from this failure will be examined to improve the reliability of future Falcon 9 missions, as stated in SpaceX’s official mission description.

Mission Details and Starlink Expansion

The deployment of the 21 satellites took place approximately 65 minutes after launch, marking another step in the expansion of SpaceX’s Starlink constellation. More than 7,000 operational Starlink satellites are currently in orbit, contributing to global broadband coverage.

This launch marked the Falcon 9 booster’s fifth and final flight. The B1086 had previously been used for three Starlink missions, as well as the GOES-U and Maxar 3 missions. SpaceX has completed 26 Falcon 9 missions in 2025, with 19 dedicated to Starlink. The company continues to advance its satellite network despite the loss of the booster in this mission.

Primordial Helium-3 May Be Locked in Earth’s Core, Study Finds

Primordial Helium-3 May Be Locked in Earth’s Core, Study Finds

Helium-3, a rare isotope formed during the early solar system, may be locked within Earth’s solid core, as indicated by recent research. This discovery could provide insights into how quickly the planet was formed. Unlike helium-4, which is commonly produced through radioactive decay, helium-3 originates from the primordial gas cloud that shaped the solar system. While traces of this isotope have been detected in volcanic hotspots and mid-ocean ridges, the mechanism behind its retention for billions of years remains uncertain. Given helium’s volatile nature, most of it was expected to escape Earth’s mantle due to tectonic activity or the giant impact that led to the formation of the Moon.

Helium and Iron Interaction at Core Conditions

According to the study published in Physical Review Letters, researchers at the University of Tokyo led by Kei Hirose examined whether helium could mix with iron under conditions mimicking Earth’s core. Using a diamond-tipped anvil, the team subjected iron and helium to extreme pressures ranging from 50,000 to 550,000 times the atmospheric pressure at Earth’s surface. As per reports, the samples were heated to temperatures between 727 and 2,727 degrees Celsius before being depressurised and analysed at cryogenic temperatures to prevent helium escape. Findings indicated that solid iron could incorporate up to 3.3 percent helium, suggesting the isotope may remain trapped in the core over long periods.

Potential Impact on Earth’s Formation Timeline

Peter Olson, a geophysicist at the University of New Mexico, told that these results confirm helium’s compatibility with Earth’s solid core. However, he noted that only 4 percent of the core is solid, with the majority existing in a liquid state. Further research is needed to determine whether helium-3 could be similarly retained in the liquid portion. Olson also highlighted the significance of this discovery in dating Earth’s formation. If helium-3 was incorporated into the core, it suggests the planet formed rapidly within a few million years. A slower formation process spanning 100 million years would likely have resulted in minimal helium retention.

SpaceX Delays Starship Flight 8 Launch After Technical Glitches

The scheduled test flight of SpaceX’s Starship Flight 8, which was expected to take off from the company’s Starbase facility in Texas on March 3, has been postponed due to last-minute technical issues. The launch was planned within a window starting at 6:30 p.m. ET with a mission to test various aspects of the rocket’s performance, including booster recovery and satellite deployment. SpaceX has not yet announced a new launch date, but updates are expected soon. The flight was set to be the eighth major test for Starship, which is designed to be the most powerful rocket ever built.

Starship’s Mission and Test Objectives

As per reports, the flight plan, Starship was expected to launch atop its Super Heavy booster, which was intended to return to the launch pad and be caught by the “chopstick” arms of the tower. The upper stage of the rocket was set to release four mock versions of SpaceX’s Starlink satellites on a suborbital trajectory before splashing down in the Indian Ocean approximately 66 minutes after liftoff. A similar test conducted on January 16 with Flight 7 saw the successful recovery of the booster, but the upper stage failed due to a propellant leak, leading to an explosion before it could complete its mission.

NASA’s Interest and Future Developments

NASA has selected Starship as the lunar lander for the Artemis program, which aims to return astronauts to the Moon in the coming years. The vehicle is also being developed for deep-space missions, including potential crewed journeys to Mars. Elon Musk, CEO of SpaceX, has indicated that future iterations of Starship may be even larger than the current model, which stands at 123 metres. The Federal Aviation Administration (FAA) is expected to grant approval for up to 25 Starship launches in 2025, marking a significant step toward the rocket’s operational use.
