** SpaceX Falcon 9 launches S. Korean ANASIS-II milcomm sat with same booster used for ISS crew mission. The booster landed safely on an ocean platform. The 51 day turnaround time was the fastest so far for reusing the Falcon boosters and faster than the best Space Shuttle turnaround of 54 days.
Both of the nosecone fairings were also captured in nets on two ships for the first dual catch on the same flight. While SpaceX has re-flown fairings recovered after landing in the ocean, it’s obviously better for reuse if they can avoid dealing with the effects of seawater and impacting the surface of the sea.

** Russian Soyuz rocket set to launch Progress cargo carrier to the ISS on Thursday: Soyuz rocket raised on Baikonur launch pad for space station resupply flight – Spaceflight Now
A Russian Soyuz rocket rolled out to a launch pad Monday at the Baikonur Cosmodrome in Kazakhstan, ready for final inspections, checkouts and fueling before liftoff Thursday with a Progress supply ship bound for the International Space Station.
The Soyuz-2.1a launcher emerged from a hangar at the Baikonur Cosmodrome just after sunrise Monday, riding a mobile railcar across the Kazakh steppe to Launch Pad No. 31. A hydraulic lift raised the launcher vertical on pad 31, and gantry arms rotated into position around the rocket to allow workers access to the vehicle for final pre-launch preparations.
Launch is scheduled for 10:26:22 a.m. EDT (1426:22 GMT; 7:26:22 p.m. Baikonur time) Thursday to kick off a three-hour pursuit of the space station. The launch time is set to occur around the time the research outpost flies over Baikonur.
The Progress will catch up with the ISS for docking in less than 3 hours after liftoff:
Russian ground teams loaded 3,351 pounds (1,520 kilograms) of dry cargo into the cargo freighter’s pressurized compartment, according to Roscosmos, the Russian space agency. Roscosmos says there’s around 1,322 pounds (600 kilograms) of propellant aboard the Progress MS-15 spacecraft for transfer into the space station’s tanks, along with 926 pounds (420 kilograms) of water and 101 pounds (46 kilograms) of compressed gas to replenish the space station’s breathing air.

** Virgin Orbit to use Japanese airport as base for some LauncherOne missions: Virgin sets up Japan spaceport to lure Asian satellite builders – Nikkei Asian Review
Asia’s first [commercial] spaceport, located at Oita Airport on the Japanese island of Kyushu, is readying support for Virgin Orbit as the company looks to fire off its LauncherOne rocket in 2022.
Virgin Orbit — a space venture of the Virgin Group — will use a modified Boeing 747, christened “Cosmic Girl,” as the launch platform for LauncherOne, which carries small commercial satellites into either a sun-synchronous or low-Earth orbit, depending on customer requirements.
In addition to its prime Oita location, the U.S.-based company has chosen four airports in the U.S. and Europe for launching satellites, including Mojave Air and Space Port in California and the U.K.’s Spaceport Cornwall at Cornwall Airport Newquay.
** An update on the Southern Launch commercial spaceport facility on the southern coast of Australia: Southern Launch prepares for lift off In South Australia – Spacedaily.com
Historically, launch sites have been constructed closer to the equator to support large satellites launches into equatorial orbit. However, direct launch to polar orbit is achieved most efficiently from launch sites nearer the poles, which have minimal interference from aviation and maritime traffic.
Southern Launch, founded in 2017, is developing a multi-user launch complex at the tip of the Eyre Peninsula in South Australia, offering a turn-key launch service solution to polar and sun-synchronous orbit.
In addition to providing the complete launch infrastructure, Southern Launch has the ability to undertake flight and range safety, vehicle design, avionics componentry and assist with launch permitting and other support services. The year-round temperate weather coupled with the highly skilled local workforce and a robust logistics supply network enables a launch site that offers high cadence launch operations at cost competitive prices.
The growing global demand for launch services and a world class launch location has attracted several early investors, with Southern Launch running an oversubscribed seed funding round at the end of 2019 with a larger Series A round to be finalised in coming months.
The first orbital rocket launch from the facility is expected in 2021.

- Space Elevators Are the Transportation Story of the 21st Century, P.Swan et al, ISEC Position Paper #2020-2 (pdf)
- Studies — International Space Elevator Consortium
From the abstract:
A new paradigm has emerged:
-
-
- space elevators can be accomplished because we now have a material
- space elevators enable interplanetary missions
- fast transit to Mars (as short as 61 days, with variations out to 400+)
- can release towards Mars EVERY day (no 26 month wait)o Can move massive amounts of cargo (180,000 MTs/year to GEO-beyond)
- space Elevators are Earth friendly
- space solar power replaces 100s of coal power plants
- no rocket exhaust to contribute to global warming
- no additional space debris
- opens up remarkable commercial enterprises at Earth Port, GEO Region +
- offer to all future scientists: any size science experiment, any solar system destination, releases every day towards multiple scientific destinations

SpaceX has carried out cryogenic pressure testing the propellant tanks of the Starship SN5 prototype currently mounted on a launch fixture at Boca Chica. If the subsequent fueling and engine tests go well, then a hop of about 150 meters will come soon after:
Will attempt to fly later this week
— Elon Musk (@elonmusk) July 21, 2020
SN5 is using a less advanced steel alloy than what is planned for operational vehicles. The SN8 prototype currently in construction is believed to be using the alloy labeled 304L – SpaceX begins building upgraded Starship prototype – Teslarati. However, Elon says the formulation of the final alloy for the Starships may not follow the standard recipe for 304L:
We’re rapidly changing alloy constituents & forming methods, so traditional names like 304L will become more of an approximation
