What we perceive to be the edge of our universe is not the actual edge of the universe, with most scientists in agreement that more space lies hidden beyond what we’re able to see. Last time out, we travelled to the very edge of our observable universe. But today, we will be going even farther, as we wade out into the darkness of the unobservable universe.

SpaceX’s Super Heavy Booster 9 prototype has rolled out to the launch site in preparation for a repeat of its pre-launch static fire test. This follows roughly two weeks after its first static fire attempt that ended prematurely at only half the expected duration. Work continues in parallel at Starbase to prepare Ship 25 for flight, which could occur in the next week or two, pending regulatory approval.

Future vehicles for Starship flights deep into next year are also in production. SpaceX is also in the midst of a major upgrade to its Starship production factory that will change the future look of the South Texas facility.

The International Space Station (ISS) is a large spacecraft in orbit around the Earth that serves as a research laboratory and spaceport for international collaboration in space exploration. It was launched in 1998 and has been continuously occupied by rotating crews of astronauts and cosmonauts from around the world since 2000. The ISS is a joint project of five space agencies: NASA (USA), Roscosmos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada). It orbits the Earth at an altitude of approximately 400 kilometers (250 miles), and provides a unique platform for scientific research, technological development, and human space exploration.

The race to space exploration has been heating up, with Elon Musk’s SpaceX making significant strides in the sector. The private company is valued at approximately $150 billion after a recent share sale by investors. Musk is speculated to own roughly 44% of the company.

The company reached an agreement with both new and existing investors to offer up to $750 million in stock from insiders at a price of $81 per share last month, valuing it at approximately $140 billion, according to a document sent by SpaceX Chief Financial Officer Bret Johnsen.

The latest share price reflects a rise of approximately 5% compared to its previous secondary sale at $77 per share. But Musk does not “anticipate needing to raise funding in the near future” and is expected to opt for secondary sales to bolster and incentivize employee and insider ownership in the company.

Following the Flight Readiness Review (FRR), NASA and SpaceX gave the go for Crew 7. The launch is scheduled for August 25th at 3:49 a.m. ET (07:49 UTC).

This mission will bring three astronauts and one cosmonaut to the International Space Station for a stay of around six months to perform experiments and conduct maintenance aboard the orbiting outpost.

After the FRR was complete, a full launch day rehearsal was carried out in which the crew was fully suited and driven to Launch Complex 39A, where they boarded Crew Dragon Endurance. The crew and mission control simulated a full countdown in order to familiarize themselves one last time before launch day.

After Russia’s Luna-25 spacecraft crashed, all eyes are on Chandrayaan-3 as India attempts to become the first nation to land on the moon’s south pole.

The robotic Luna-25 spacecraft appeared to have “ceased its existence” after a failed orbital adjustment, the space agency Roscosmos said.

A US Coast Guard notice gives the first possible date window for the next SpaceX Starship orbital launch attempt.

Page 4 out of 88 pages has a coast guard notice to mariners that starting August 31, 2023 there could be dangerous rocket operations.

SpaceX recently installed the new hot staging ring atop Booster 9 that will attempt this new stage separation method.

The hot staging ring has gone through its own test campaign, including being connected to the “can crusher,” which simulates stresses on the rocket during liftoff and, having passed that test, was then installed.

Hot staging is when the 2nd stage, in this case, Starship, ignites its engines while still connected to then pull away from Booster 9, which will also still be firing some of its own engines but with those throttled down. The hot staging method isn’t a new idea, as it has been used by Russian rockets for years now and also by older American rockets such as the Titan II.
