A former SpaceX employee gives a fascinating account of what it is like to work there

Link here. The account is everything you would expect. The work culture is open, efficient, and aggressive. You need to provide value and be self-motivated or you will not survive.

This one story reveals a lot:

[I]f I was in a meeting and it was adding value to what I did daily, stay, or if I was adding value based on my expertise, stay — but if neither of those things were happening, you should get up and respectfully walk out.

In one instance, a government customer came in with a 50-slide deck. Six slides into the presentation, 75% of the room had walked out. I had to tell him that if he didn’t get to the point, I’d be the only person left in the room — and only because I had to walk him out. He skipped ahead to his last five slides. That kind of environment makes you much more efficient.

I bet there are a lot of corporate workers reading this that fervently wish they had the right to walk out of a meeting that was wasting their time. Furthermore, consider that government customer: He or she brought a slide deck where 90% of the slides were fluff. That indicates the kind of work atmosphere he or she comes from.

For smart people who want to be creative, it would be an incredible pleasure to work in such an environment. No wonder SpaceX produces such good products.

Redwire developing a satellite designed to fly in extremely low orbits

The orbital manufacturing company Redwire is now developing a satellite, dubbed SabreSat, to fly for long periods in extremely low orbits where the atmosphere would normally cause the orbit to quickly decay.

SabreSat, Redwire Space’s satellite for very low Earth orbit, looks more like a dart than a traditional spacecraft. “As you think about aerodynamics, you want the dart to be skinny and long, not stubby and fat,” Spence Wise, Redwire senior vice president for missions and platforms, told SpaceNews.

Redwire is designing SabreSat for government intelligence, surveillance and reconnaissance missions.

The satellite would fly in orbits from 55 to 200 miles altitude. By flying so low it will get far better images and ground data than spacecraft in higher orbits. It will also be less vulnerable to attack compared to high altitude aerial reconnaissance balloons or airplanes.

Its dart-like shape will meanwhile reduce friction so that less fuel will be required to maintain its orbit.

Orbital tug startup Starfish Space wins $37.5 million contract from Space Force

Even though problems with another company’s deployment system prevented a docking test in orbit last month of its Otter Pup tug, the orbital tug startup Starfish Space has won a $37.5 million contract from Space Force to further develop its autonomous rendezvous and docking system.

The newly announced $37.5 million Space Force contract will support the development of an Otter demonstration spacecraft over the course of the next four years. In its announcement of the fixed-price contract — which was awarded through the Strategic Funding Increase program, or STRATFI — the Department of Defense said the project’s goal is to “improve maneuverability on-orbit and enable dynamic space operations docking and maneuvering of Department of Defense assets on-orbit.”

Though the docking test was prevented when the tug deploying Otter Pup (owned by a different tug company, Launcher) went into an unplanned spin, Otter Pup was deployed and brought under control. Those maneuvers however used up most of its fuel. Engineers were still able to work with another orbital tug company, D-Orbit, to maneuver and rendezvous with that company’s ION tug and thus succeed in demonstrating Pup’s rendezvous technolgoy.

Chang’e-6 enters lunar orbit

Chang'e-6 landing zone

China’s Chang’e-6 sample return spacecraft successfully entered lunar orbit today, in preparation for its mission to land and bring back material from the the far side of the Moon. The landing zone is indicated by the red box on the map to the right, on the southern rim of Apollo Crater in the southern hemisphere. That crater is inside South Aitkin Basin, one the Moon’s largest impact basins.

The spacecraft will next adjust its orbit to prepare for sending its lander-ascender sections down to the surface. If the landing goes well, it will drill into the surface, place some material into the ascender section, which will then lift-off and dock with the orbiter-return section in orbit. The material will be transferred into the return section, which will separate and bring the material back to Earth, sometime in late June.

Launch of first manned flight of Starliner rescheduled for May 17, 2024

Because ULA engineers have decided they need to replace the valve that forced a launch scrub on May 8th, the first manned launch of Boeing’s Starliner capsule to ISS has now been rescheduled to May 17, 2024.

The oscillating behavior of the valve during prelaunch operations, ultimately resulted in mission teams calling a launch scrub on May 6. After the ground crews and astronauts Butch Wilmore and Suni Williams safely exited from Space Launch Complex-41, the ULA team successfully commanded the valve closed and the oscillations were temporarily dampened. The oscillations then re-occurred twice during fuel removal operations. After evaluating the valve history, data signatures from the launch attempt, and assessing the risks relative to continued use, the ULA team determined the valve exceeded its qualification and mission managers agreed to remove and replace the valve.

Replacing the valve is a somewhat routine procedure, but it will take a few days, causing the two-week delay.

Sweden’s Esrange spaceport gets its first orbital customer

Proposed spaceports surrounding Norwegian Sea
Proposed spaceports surrounding Norwegian Sea

Sweden’s Esrange spaceport today announced it has signed its firs orbital rocket customer, Perigee Aerospace from South Korea.

In its 7 May announcement, SSC explained that Perigee Aerospace expected to launch the first Blue Whale 1 mission from Esrange no earlier than 2025 following a successful maiden flight from South Korean soil.

…Blue Whale 1 is a two-stage rocket that will stand approximately 21 metres tall and feature a reusable first stage.

Esrange was originally built by an earlier version of the European Space Agency in 1964, then transferred to Sweden in 1972. Until until a orbital launchpad was installed 2023 it was solely dedicated to suborbital flights. It now is attempting to attract the new commercial rocket industry, as well as compete with the other new nearby spaceports, as shown on the map.

This new rocket from South Korea is also news, as it indicates that the fever for capitalism in space has even reached that country.

Musk: SpaceX and Starlink don’t use artificial intelligence

During an interview at a recent conference Elon Musk admitted that both SpaceX and Starlink have found artificial intelligence (AI) lacking, and don’t use it at all.

The irony was that prior to this admission, Musk had been extolling AI’s potential, predicting it would someday do wonderful things.

Musk, who answered questions during 27th annual Milken Institute Global Conference on Monday, spent a sizable portion of his talk extolling the benefits of artificial intelligence. At one point, he said a “truth-seeking” AI could “foster human civilization” when asked about the role the technology would play in human’s everyday lives.

But when asked whether AI could “accelerate” his efforts in space exploration, he seemed less excited about the technology. …”I mean, oddly enough, one of the areas where there’s almost no AI used is space exploration,” Musk replied. “So SpaceX uses basically no AI, Starlink does not use AI. I’m not against using it. We haven’t seen a use for it.”

Musk continued, saying that he’s been testing improved AI language models by asking them questions about space — and the results have been disappointing. “With any given variant of or improvements in AI, I mean, I’ll ask it questions about the Fermi paradox, about rocket engine design, about electrochemistry — and so far, the AI has been terrible at all those questions,” Musk said.

Here we see the visionary meet the practical engineer/businessman. Musk always looks to the future with grand visions, but when it comes time to build those visions, he never allows his vision to interfere with practicality. AI is still essentially garbage-in-garbage-out. The rush by businesses and tech-firms to blindly use has resulted in more than a few disasters.

Musk doesn’t do anything blindly. He tested AI first, found it wanting, and thus put it aside, despite believing it will someday do wonderful things.

If only more companies used this approach. If they had, they might not have blindly pushed DEI and ESG requirements that have done nothing but harm to their companies, their work forces, and their bottom lines.

SpaceX unveils the spacesuit Jared Isaacman will use to do the first private spacewalk

SpaceX this past weekend unveiled the spacesuit that Jared Isaacman will use on his Polaris Dawn mission, presently scheduled for this coming summer, to do the first spacewalk by a private citizen.

This spacewalk suit is based on SpaceX’s flight suits that astronauts presently wear when inside Dragon, but is much more capable. From SpaceX’s webpage:

Developed with mobility in mind, SpaceX teams incorporated new materials, fabrication processes, and novel joint designs to provide greater flexibility to astronauts in pressurized scenarios while retaining comfort for unpressurized scenarios. The 3D-printed helmet incorporates a new visor to reduce glare during the EVA in addition to the new Heads-Up Display (HUD) and camera that provide information on the suit’s pressure, temperature, and relative humidity. The suit also incorporates enhancements for reliability and redundancy during a spacewalk, adding seals and pressure valves to help ensure the suit remains pressurized and the crew remains safe.

Creating this suit was the main reason Isaacman’s five day orbital Polaris Dawn mission was delayed by almost two years.

I wonder what it cost SpaceX to develop this new suit. I strongly suspect it was much cheaper than the spacesuits NASA has hired Axiom and Collins Aerospace to create. It certainly has been built faster.

Rocket Lab delays first launch of new Neutron rocket

Rocket Lab has delayed the first launch of its new larger Neutron rocket from late 2024 to mid-2025 in order to complete the testing of that rocket’s new methane-fueled Archimedes engine.

Many component, subsystem, and all-up system tests will be conducted throughout the test campaign. These tests will validate Archimedes’ transient start-up, steady-state, and shut down performance. The engine test and development campaign is a key driver of the schedule for Neutron’s first launch, which the Company today confirmed is now expected to take place no earlier than mid-2025.

That testing will also certify it for use in as many as twenty flights, as the Neutron rocket is being designed from the get-go to be reusable.

China successfully completes first launch of new Long March 6C rocket

China today successfully completed the first launch of its new Long March 6C rocket, lifting off from its Taiyuan spaceport in the north interior of China.

The rocket uses kerosene as its fuel, rather than the toxic hypergolic fuels used in its older rockets, and is part of an effort to replace all those older rockets. Thus, when its lower stage crashes inside China, the risks of it harming anyone is reduced somewhat. China released no information on where that first stage crashed on this first launch.

The rocket placed four satellites in orbit.

The leaders in the 2024 launch race:

47 SpaceX
19 China
6 Russia
5 Rocket Lab

American private enterprise still leads the world combined in successful launches, 54 to 31, with SpaceX by itself leading the rest of the world, including other American companies, 47 to 38.

Starliner launch scrubbed due to valve issue

Yesterday’s Starliner launch was scrubbed before launch because ULA had detected an issue with a valve on the Atlas-5’s Centaur upper stage, causing that valve to flutter because it had not closed in the proper position.

At the press conference that followed, ULA’s CEO Tory Bruno explained that during an unmanned launch, engineers would have simply cycled the valve, which almost always works to get it to seat properly. ULA launch rules however forbids it from doing so on a manned launch, because that would be the equivalent of fueling the tank with people on board the rocket. The Atlas-5 was initially not built for manned flights, and though it has been upgraded to man-rate it, those upgrades did not permit ULA this capability, unlike SpaceX’s Falcon 9, which get fueled entirely after the crew boards Dragon.

They are reviewing the data to see if the valve will need to be replaced. If not, the launch could happen quickly. If it does, the launch will be delayed slightly longer, but not significantly. Right now ULA, NASA, and Boeing are targeting a May 10th launch.

It is worth listening to Tory Bruno’s explanation of the situation because of its clarity. I have embedded his comments below, time-stamped to when he began speaking.
