** SpaceX launches Falcon 9 with 58 Starlink broadband sats and 3 earth imaging sats for Planet. The first stage booster flying on its 6th flight made a successful landing on an ocean platform. One nosecone fairing was caught in a net (see below) and the other was recovered after setting down on the water.
A fairing from the Starlink 10 launch makes a leisurely return onto a calm summer sea:

Today, the Blue Origin-led Human Landing System (HLS) National Team – comprised of Blue Origin, Lockheed Martin, Northrop Grumman, and Draper – delivered an engineering mockup of a crew lander vehicle that could take American astronauts to the Moon. The lander is set up in the Space Vehicle Mockup Facility (SVMF), NASA Johnson Space Center’s (JSC) iconic Building 9.
The full-scale engineering mockup showcases two elements of the National Team’s multi-element architecture – the Ascent Element (AE) and Descent Element (DE). Standing at more than 40 feet, it is the Blue Origin National Team’s update to Apollo’s Lunar Module (LM) and will be used to validate the National Team’s approaches for getting crew, equipment, supplies, and samples off and on the vehicle. The team will collaborate with NASA organizations including JSC’s Astronaut Office to perform engineering and crew operations tests with astronauts aiming to fly the final system within several years.
“Testing this engineering mockup for crew interaction is a step toward making this historic mission real,” said Brent Sherwood, vice president of Advanced Development Programs, Blue Origin. “The learning we get from full-scale mockups can’t be done any other way. Benefitting from NASA’s expertise and feedback at this early stage allows us to develop a safe commercial system that meets the agency’s needs.”
The National Team HLS design leverages significant prior work, flight heritage, and a modular solution. Modular solutions help to enable faster progress due to the independent development and testing of each element, which permits ongoing improvements and evolution without impacting the full system. This also provides flexibility in the use of different launch vehicles and different concepts of operations.
The Descent Element is based on Blue Origin’s Blue Moon cargo lander and BE-7 LOX/hydrogen engine, both in development for more than three years. The Ascent Element incorporates avionics, software, life support hardware, crew interfaces, and mission operations from Lockheed Martin’s human-rated, deep-space Orion vehicle that will fly on the Artemis I and II missions. A consistent cockpit experience and training from Orion to the AE makes the end-to-end mission safer for Artemis. The Transfer Element, a propulsive stage that starts the lander on its descent trajectory from lunar orbit, is based on Northrop Grumman’s Cygnus vehicle that provides logistics resupply to the International Space Station; and Draper provides descent guidance and avionics to the National Team.

** LinkSpace of China flies RLV-T5 vertical takeoff and landing rocket:
The rocket, named RLV-T5 (NewLine Baby), blasted off at 10:35 am Beijing time at Linkspace’s launch base in Lenghu Town, Mangya City, northwest China’s Qinghai Province.
With a total length of 8.1 meters and a diameter of 65 centimeters, RLV-T5 has a takeoff weight of about 1.5 kilograms.
It reached a new height of 300 meters before landing steadily and accurately at the designated area with little deviation. The whole process lasted for 50 seconds.
Today marked the third successful trial conducted by the company. Before this, RLV-T5 made two quick jumps experiments at a relatively low height in China’s Shandong Province this year.
According to the company, as China’s largest recyclable rocket, RLV-T5 is designed to serve as an initial sample, providing experience for further suborbital reusable rocket and on-orbit reusable rocket development.
Here’s a proposed vehicle for suborbital commercial services:

Skyrora has successfully launched its two-stage, four-metre tall sub-orbital rocket, Skylark Micro from the company’s mobile launch complex set up within a few days at Langanes Peninsula, Iceland. The rocket climbed to 26.86km in altitude before both stages were parachuted back down to sea.
The launch is part of Skyrora’s de-risking program leading up to the building and launching of its orbital vehicle, Skyrora XL, scheduled for 2023. The launch of Skylark Micro was to test onboard electronics and communications that will also be used in the larger Skylark-L and Skyrora XL launch vehicles. Before launch, the team undertook a number of weather procedures to learn more about the mid and upper-level wind speeds and altitudes. In addition, the mobile launch complex allowed the team to collect a large amount of data of telemetry, GPS tracking, and weather conditions during the flight to which they are currently analysing. The test also allowed the Skyrora crew to practice launch procedures and marine recovery operations.
Despite the ongoing heroic efforts of the Langanes Search and Rescue and Skyrora Recovery teams, Skyrora has unfortunately been unsuccessful in their efforts of locating the Skylark Micro booster and sustainer stages. However, they are still continuing search operations for the next few days as well as learning how to improve future recovery operations. Creating another test of our suborbital mobile launch complex in a different location demonstrates the immense speed and flexibility of Skyrora for launching its test rockets.
Here’s footage of Skyrora launching its Skylark Micro rocket from Iceland on Sunday, reaching 26.86km – the company’s highest altitude yet by about 20km. pic.twitter.com/jTWzW8Ekfa
A startup formed by rocket engineers from the German space agency DLR is targeting late 2022 for the first flight of a small launch vehicle designed around hybrid engines.
HyImpulse is developing a three-stage rocket capable of sending 500 kilograms to a 400-kilometer low Earth orbit. The 40-person company is bankrolled by Rudolf Schwarz, chairman of German technology company IABG, and has a 2.5 million-euro ($3 million) grant from the European Commission to advance its launcher technology, Christian Schmierer HyImpulse co-CEO, said in an interview.
HyImpulse is seeking to differentiate itself by using hybrid engines that run on a paraffin-based fuel and liquid oxygen. The combination of fuels should result in a rocket with simpler hardware than a liquid-fueled system and greater safety than solid fuels, Schmierer said.
** Firefly testing booster of Alpha rocket that is to launch this autumn:
** Reusing the Falcon 9 booster fairings pays off in just 2 to 3 flights according to Elon Musk:
Payload reduction due to reusability of booster & fairing is <40% for F9 & recovery & refurb is <10%, so you’re roughly even with 2 flights, definitely ahead with 3
This refutes the long held claims of ULA managers and many others in the space industry that numerous re-flights are required to make reusable launch vehicles pay off financially. The RLV skeptics believe, in turn, that they cannot justify investment in RLVs without first seeing a demand from customers for high numbers of launches.
However, without a drop in launch prices by a factor of 10 to 100 (i.e. to low $100s per kg rather than several $1000s), which is only feasible with reusability, high-launch rate markets such as orbital space tourism cannot emerge. This chicken and egg dilemma has been a persistent impediment to progress in space development.
SpaceX took advantage of expendable flights for paying customers to enable the testing of returning a stage from high altitudes and hypersonic speeds and executing a powered landing. This cost-saving approach plus a willingness to learn from multiple failures and persist with the effort, let SpaceX break through this impediment.
Elon also refutes the belief inspired by the Space Shuttles that recovery/refurbishment must necessarily be tremendously costly. The Shuttle program employed a standing army of about 10,000 people who toiled for at least two months to return an orbiter to the launch pad. Although the shortest time between re-flights of an F9 booster so far is 51 days, the 10% cost number from Elon implies that there is a fairly limited number of people involved with the turnaround activities. The current turnaround times may have as much to do with scheduling and logistics issues as they do with the degree of refurbishment work required.
Elon has long claimed that a turnaround of a day or two could eventually be achieved with the F9 boosters. However, with the emphasis now on the fully reusable, fast turnaround Starship/Heavy Booster system, we are unlikely ever to see a super-short turnaround of a F9 booster.
*** Merlin engine refurbishment is the most difficult challenge to flying F9 stages multiple times:
I don’t want be cavalier, but there isn’t an obvious limit. 100+ flights are possible. Some parts will need to be replaced or upgraded. Cleaning all 9 Merlin turbines is difficult. Raptor is way easier in this regard, despite being a far more complex engine.
On July 14, just two weeks after the successful SpaceX Falcon 9 launch of the Lockheed Martin-built GPS III Space Vehicle 03 (SV03) satellite for the United States Space Force, Cape Canaveral Air Force Station took delivery of the GPS III Space Vehicle 04 (SV04) GPS satellite from The U.S. Space Force Space and Missile Systems Center (SMC). The GPS III SV04 satellite, like its predecessor GPS III SV03, is scheduled to launch aboard a SpaceX Falcon 9 no earlier than September.
In a statement provided by the U.S. Air Force, SMC’s Medium Earth Orbit Space Systems Division chief, Col. Edward Byrne, said that “the delivery of SV04 marks the start of our third GPS III launch campaign on a SpaceX Falcon 9 rocket and brings us another step closer in advancing the GPS constellation with more capable satellites.” The SpaceX Falcon 9 previously lifted the GPS III SV01 and SV03 satellites to orbit in December 2018 and June 2020 respectively.
The nearly $2 billion in fresh capital was oversubscribed and is the largest fundraising round yet for SpaceX, according to PitchBook.
News of the funding was first reported by Bloomberg, which said that the private company will now have a valuation of $46 billion, citing people familiar with the matter.
**** Starship
The SN6 prototype Starship passed its pressure tests last weekend and since then a Raptor engine has been installed. A test firing of the Raptor is expected early next week. If that goes well, a hop to 150 meter or so, similar to the one flown by SN5, could soon follow. The goal is to do many short flights to debug the hardware and software, and become adept at operational tasks.
The SN8 prototype is rapidly coming together. It is expected to be fully fitted out with nosecone section and body flaps. Here is a current sketch of the state of its assembly:
Update! SN8’s forward dome stack has been stack on top of the common dome stack. Now only 4 pieces left, plus fins, until we have a full 20km worthy Starship!
The SN8 could be the first prototype Starship to go on a high altitude flight like the one simulated in this animation:
Very impressive render. Note, legs will be bigger & there’ll be way more stuff in engine bay. Main engines actually do majority of work in turning ship vertical before landing.
Max demonstrated Raptor thrust is ~225 tons & min is ~90 tons, so they’re actually quite similar. Both Merlin & Raptor could throttle way lower with added design complexity. Raptor preburner & Merlin gas generator flameout are what limit lower bound.
SN40 is about to be tested & has several upgrades over 330 bar engine. For reference, 330 bar on Raptor produces ~225 tons (half a million pounds) of force.
