The latest launch for Rocket Lab failed as their Electron Rocket exploded after it entered its second stage. This resulted in the destruction of several satellites onboard which were due to be inserted into orbit. The company has had numerous successful launches and is trying to maintain frequent launches of its 3-D printed rockets.
Research on the exoplanet WASP-76b revealed that the planet can reach temperatures of 2,400 C during the day. Due to this, scientists theorized that iron could melt in these temperatures and that the wind could blow the iron to the cooler part of the planet where it could turn to rain. Thus, iron rain could be possible.
A new exoplanet, AU Mic b, has been discovered around a nearby star, AU Microscopii. The planet is about the size of Neptune but instead of being far away from the star it is so close that it only takes 8.5 days to orbit the star. For our Sun it takes Earth 365.25 days to make a full orbit and Neptune takes 164.8 years (yes years) or 60,182 days. AU Microscopii is a bit different from our Sun. It is 32 light years away but still very young and a red dwarf which is much smaller than our sun. Since it is so close it could be a hot Jupiter, a gas giant that forms too close to its sun and have their atmospheres blown away. This is a gradual process though so since AU Microscopii and AU Mic b however the development of AU Mic b will be exciting for astronomers to study and gain insights into.
20 new moons were discovered around Saturn causing it to be the planet in the Solar System with the most moons, surpassing Jupiter. Most are fairly small with differing orbits but the discovery now increases the future possibilities for missions to Saturn, new targets for exploration and a bunch of names from mythology we don’t really understand but have heard somehow before.
Firefly Aerospace is aiming for late October to begin testing their Firefly Alpha rocket. They are a contractor to NASA via the Commercial Lunar Payload Services (CLPS) program which is developing landers and rovers for the Moon. They haven’t sold anything yet but can keep pitching designs for future projects. They are working up to a space plane design, similar to the old Space Shuttle.
Blue Origin has delivered their BE-4 rocket engine to the United Launch Alliance for use in their Vulcan Centaur rocket. Origin is playing catch-up to SpaceX’s great success and real world tests of their technology will begin giving them the data they need to further develop their space travelling ambitions.
Aerojet Rocketdyne has managed to successfully test a 3-D printed rocket. The use of 3-D printing in spaceflight has been studied before and is being pursued by others as a way to reduce the number of parts the rockets require and to lower some costs. The company Relativity Space is trying to fully 3-D print their rockets in order to launch them faster and lower costs to extreme lows compared to the $500 million price tag on some of the past rockets. As the testing continues we will see whether the printing continues or shuts down.

The United Kingdom has purchased the bankrupt company OneWeb. This company wanted to compete with SpaceX’s Starlink program which is a network of satellites in space that can provide internet access. The U.K. will maintain a large equity share in the company and are hoping to use it for Positioning, Navigation and Timing (PNT). They are leaving the EU and are no longer able to use the shared satellite network. OneWeb is currently based in Florida but will later move to the U.K.
