SpaceX (general discussion)

According to what’s been posted on NSF the ISS deorbit vehicle will need to be launched with 15 tons of fuel, will be based on Dragon heritage and is a specialised one off vehicle that though built by Space X will be operated by NASA.
 
As the search on here doesn’t appear to be working at the moment and therefore I cannot find the Axiom thread I will post this here.

Axiom plans to test orbital-based data center on ISS this year:

Later this year, Axiom Space is set to launch a prototype of the Axiom Data Center Unit (AxDCU) to the International Space Station (ISS). This prototype will be instrumental in laying the foundation for a future orbital data center infrastructure for Axiom Station. Learn more: https://bit.ly/3VlXPbV.

Does a suitable upper stage exist? If Dragon 2 can carry 7,000lb payload what if they just expanded the tanks on a Dragon 2 capsule? Would 7,000lbs be enough? Would it even be able to dock in a suitable location?

IIRC the ship that boosts (or deorbits) the station has to be berthed, not docked, because of the spot it does this from. SpaceX Dragon 1 capsules (the older commercial cargo vehicle) are all berthed, so they have the knowhow and parts available for this.

Dragon design is a bit weird in that all the thrusters, their tanks and plumbing are outside the primary primary pressure vessel, distributed around the docking port/tunnel. This makes expanding tanks a bit difficult (they are volume limited), but given that the deorbit tug won't need to have habitable interior, I suspect that the solution is basically to cut a hole in the pressure vessel and put a tank inside Dragon.

No, it will from the main docking port at the end of the station, where Starliner is currently located

No, it will be adding tankage to the trunk and it won't be a standard Dragon since the thrusters are not located properly for the task. And likely not even use the Dragon pressure vessel.
 
Why a relatively small space telescope is being launched on a Falcon 9.

COSI is a relatively small spacecraft, built by Northrop Grumman and weighing less than a ton, but it will ride alone into orbit on top of a Falcon 9 rocket. That's because COSI will operate in an unusual orbit about 340 miles (550 kilometers) over the equator, an orbit chosen to avoid interference from radiation over the South Atlantic Anomaly, the region where the inner Van Allen radiation belt comes closest to Earth’s surface.

SpaceX's Falcon 9 will deliver COSI directly into its operational orbit after taking off from Cape Canaveral, Florida, then will fire its upper stage in a sideways maneuver to make a turn at the equator. This type of maneuver, called a plane change, takes a lot of energy, or delta-V, on par with the delta-V required to put a heavier satellite into a much higher orbit.

NASA selects SpaceX to launch a gamma-ray telescope into an unusual orbit

The Falcon 9 rocket is pretty much the only rocket available to launch this mission.

The Space Bucket has video out about SpaceX's construction activities at LC-39A in Florida and how some space companies (Blue Origin, ULA) are reacting to this:


With SpaceX quickly building necessary infrastructure at sites like LC-39A in Florida, eventual Starship launches are not far away. SpaceX and Elon have expressed in the past that while Boca Chica is a great test site and facility, the future of the vehicle likely lies in Florida. Even new reports suggest that SpaceX wants the capability to launch Starship 120 times a year from that state.

With this being said, some companies in the area are not too fond of what this could mean. Both Blue Origin and United Launch Alliance have submitted comments on the FAA’s EIS of Starship in the area. Their comments include concern about Starship’s impact on their employees, general operations, noise, health, etc. Here I will go more in-depth into what both companies had to say, the significance of these comments, future plans, and more.

DoD is eager to diversify its rocket portfolio and will likely throw money at BO, since it is another large most reusable rocket outside the F9 near monopoly.

NSS learned its lesson from EELV and ULA, that why when I was at the SPO we wrote the New Entrants Certification Guide, of which I was a reviewer.

Not really.the DOD isn't going waste money when BO is throwing its own money and the DOD has ULA.
 
Booster 12 is moved to Launch site

while Falcon 9 B1076 made it 15th launch and landing
bring a Turkish communications satellite into GTO

five launches until SpaceX reach the total launch number of Titan Rockets (368).
this could either Polaris Dawn 2 or ASBM 1 end July

Composites looked to be the initial idea.

Remember, Musk has the old Beal facility---and Beal had one of the largest filament winding machines ever made. I don't know what happened to that---but the composite tank that failed was said to come from Japan---so who knows?

Now, might some ablative recipes also allow them to serve as tile adhesives?

If so, there is only a need to “spackle” missing tiles—not a whole tear down.

Longer tankage and additional propellant will make up for the mass, I trust.

I would like to see Elon look at new tesselations. One known as “the hat” may be of use:

Convair study for NEXUS a diameter of 36 to 61 meter, they consider it feasible to handle.
Also Martin for there NOVA rocket with diameter 30 meter
They look into Hybrid assembly/launch tower

Oh by the way
SpaceX use a Hybrid assembly/launch tower
and second Launch tower start stacking
