The sixth test flight of SpaceX’s Starship, the world’s largest rocket, was successfully conducted on November 19. The 400-foot (122 metres) rocket, developed by Elon Musk’s private space company, lifted off at 5:00 pm EST from the Starbase facility in South Texas. Despite high anticipation for a repeat of its previous booster catch using the launch tower’s “chopstick” arms, the Super Heavy booster was instead directed to a controlled splashdown in the Gulf of Mexico due to a safety parameter being triggered.

Booster Catch Attempt Deferred

The planned booster recovery had to be cancelled as per data assessed mid-flight, confirmed Dan Huot, a SpaceX representative during the live webcast. The booster splashed into the Gulf seven minutes after launch. A previous flight in October demonstrated a successful tower catch, marking a significant milestone for reusable rocket technology.

Milestones Achieved in Starship’s Upper Stage

The upper stage of Starship, known simply as “Ship,” followed a semi-orbital trajectory similar to that of the fifth flight. For the first time, the spacecraft carried a payload – a banana serving as a zero-gravity indicator. This flight tested modifications to its heat shield and new thermal protection materials while also performing an engine re-light during flight to validate re-entry manoeuvres critical for future orbital missions.

Enhanced Observations of Re-Entry

Unlike previous flights, this mission was timed for better visibility of the Ship’s descent. The spacecraft survived the intense re-entry process and executed a vertical splashdown in the Indian Ocean near Australia. Observers noted the craft’s resilience despite testing a less advanced heat shield.

Jessica Anderson, a SpaceX manufacturing engineering manager, described the results as remarkable during the live webcast. Co-host Kate Tice, a senior quality engineering manager, also acknowledged the significance of the successful descent amidst these challenges.

Political Attendance Highlights Interest

President-elect Donald Trump was among those present at the event, underlining his growing rapport with Elon Musk. Trump, who has recently appointed Musk to co-lead a government efficiency group, showed visible support for the Starship programme during this high-profile launch.

Glaciers Speed Up in Summer and Slow in Winter, New Global Map Reveals

Published

By

A new global map of glacier speeds, built from nearly a decade of satellite observations, shows that glaciers consistently move faster in summer and slower in winter. Meltwater acts as a natural lubricant, accelerating flow during warm months. Scientists warn that glaciers with strong seasonal shifts are likely to speed up long-term, adding to future sea-level rise.

Engineers Turn Lobster Shells Into Robot Parts That Lift, Grip and Swim

Published

Engineers have transformed discarded crustacean shells into functional biohybrid robots by softening the shell segments, adding elastomers, and attaching motors. These recycled structures can lift weight, grasp delicate items, and even propel small swimmers. The project demonstrates how food waste can become a sustainable robotics resource, though challenges remain wi…
