SpaceX achieved another milestone this week as the Starship and Super Heavy prototype were stacked and fully-integrated for the first time!
Once again, things are gearing up at SpaceX’s South Texas Launch Facility, located just outside the village of Boca Chica, Texas. In recent weeks, the aerospace community has been abuzz about the rollout and Static Fire test of the Super Heavy Booster 3 (B3) prototype. This was the first time a booster was tested, which will be responsible for launching the Starship to space in the near future. Since then, things have only ramped up some more.
First, there was the announcement on Aug. 2nd that the fourth Super Heavy prototype (the BN4) received a full complement of 29 Raptor engines and grid fins. This was followed on Aug. 3rd with news that BN4 was being moved to the launch pad and that the SN20 Starship prototype received a full six Raptor engines. On Aug. 6th, the denouement came with the stacking of both prototypes together, which resulted in the tallest rocket in the history of spaceflight!
Together, the integrated Starship stood around 120 meters (390 feet) tall, while the addition of the orbital launch stand increased that to 145 m (475 feet) – which is taller than the Pyramid of Giza (138.5 m; 454 ft). The stacking was the first time that the Starship and Super Heavy were fully integrated, a major milestone for the company that puts them one step closer to making an orbital flight test.

NASA’s Perseverance Mars rover recently attempted its first-ever sample collection of the Martian surface on August 6. However, data shows that while the rover’s drill successfully drilled into the surface, no regolith was collected in the sample tube.
Meanwhile, as Perseverance was preparing for the sample collection event, a team of researchers using ESA’s Mars Express orbiter found evidence that previously thought of lakes of water underneath Mars’ south pole might actually be made of clay.
Perseverance’s sample collection failure
On August 6 Perseverance’s 2-meter robotic arm lowered to the Martian surface, where a drill located at the end of the arm began carving into the local rock.
Wind farms certainly allow for the production of clean energy. Although they are 100% renewable, they still have problems. They have high costs, disfigure the landscape, produce noise pollution, and above all, have a heavy impact on fauna, and in particular on birds.
The Spanish startup Vortex Bladeless has developed a bladeless turbine that can revolutionize wind energy, especially at the household level, and become the alternative to solar panels. The design of the Spanish firm has already received the approval of Norway’s state energy company, Equinor.
The new turbine, which has also been called the “Skybrator” due to its phallic shape, is capable of harnessing energy from winds without the sweeping white blades everyone associates with wind power. It generates wind energy thanks to vibration and without generating the environmental and visual impact on the fauna of the large wind farms.
A new study on thin films of glass shows how they can be fabricated to be denser and more stable, providing a framework for new applications and devices through better design.

NASA’s Perseverance drilled into the surface of Mars but failed in its initial attempt to collect rock samples that would be picked up by future missions for analysis by scientists on Earth.
