SpaceX launches

Didn’t someone shoot themselves in the foot with an eerily similar concept a while back?

I suppose it might just work this time.

New technology!

If you read Arthur C Clarke he predicted a lot of this about 70 years ago.

Jules Verne predicted a lot more than this.

Nice start and booster landing in fog. Total mission success.

SpaceX’s 10th mission of the year was the first with no planned landing, carrying the AMOS-17 satellite to GTO. This mission is provided by SpaceX to Spacecom for free due to the AMOS-6 static fire failure, which destroyed the satellite and precluded the launch. This mission was launched from SLC-40 at Cape Canaveral AFS on a Falcon 9, and the first-stage booster was expended.

This was SpaceX’s tenth mission of 2019, the third GTO launch of the year and the seventy-fourth Falcon 9 launch overall. It re-used the Block 5 booster flown on the Telstar 19V and Es’hail 2 missions for its final flight.

For this launch SpaceX will attempt it’s second untethered hop of the prototype launch vehicle colloquially known as Starhopper from their Boca Chica facility in Texas. The vehicle is expected to ascend using it’s single Raptor engine to an altitude of 200m 150m before performing a controlled landing. The primary aim of the mission is to test the flight dynamics of both the vehicle and the Raptor engine to better inform decisions concerning their next generation launch vehicle Starship. The vehicle has also been outfitted with a sample of hexagonal TPS (thermal protection system) tiles, whilst this flight will not approach the alititudes and velocities needed to test their thermal properties during re-entry, it does offer an opportunity to subject the tiles to some rigorous shaking to check that they wont fall off. Previously, Starhopper performed a short tethered hop and a 20m untethered hop - this will be the final flight for the vehicle before it is retired and superseded by the Mk.1 and Mk.2 orbital prototype Starships under construction in Boca Chica (Tx.) and Cocoa (Fl.).


Next week (11.11) another set of 60 Starlink satellites are planned to be launched into space.

Starlink-1 mission

SpaceX is going to launch its second batch of next-generation communication satellites. This mission will fly on a booster which already has flown 3 times. It is also going to be the first time that payload fairings will be reused.

Liftoff currently scheduled for: 10:56:00 pm CST, November 11, 2019 (9:56 AM local)
Past flights of this core: 3
Payload mass: 60 * 260kg = 15 400kg
Payload: 60 Starlink version 1 satellites
Core: B1048


SpaceX designed Starlink to connect end users with low latency, high bandwidth broadband services by providing continual coverage around the world using a network of thousands of satellites in low Earth orbit.

Lot of facts

Awesome, the first stage came back from space and landed for the 4th time!

SpaceX’s 19th Commercial Resupply Services mission out of a total of 20 such contracted flights for NASA, this launch will deliver essential supplies to the International Space Station using the reusable Dragon 1 cargo spacecraft. The external payload for this mission is Japan’s Hyperspectral Imager Suite (HISUI). This mission will launch from SLC-40 at Cape Canaveral AFS on a Falcon 9, with first stage landing prospects currently unknown.

This is SpaceX’s 12th mission of 2019, the 3rd and final CRS flight of the year and the 76th Falcon 9 launch overall. It will use a brand new Block 5 booster, B1059, and re-use a twice-flown Dragon 1 spacecraft, C106.


Name Type Operator Orbit Mass Mission
Internal Cargo Resupply NASA ISS LEO (≈400 x ≈400 km, 51.66°) 1693 kg Deliver supplies, equipment and experiments to support ISS science and operations.
HISUI Remote Sensing Japan ISS LEO (≈400 x ≈400 km, 51.66°) 550 kg Hyperspectral remote sensing instrument for resource discovery and management.
Li-Ion Battery ISS Maintenance NASA ISS LEO (≈400 x ≈400 km, 51.66°) 370 kg Li-Ion battery for the station’s power system to replace a older, degraded unit.
ELaNa 25B and ELaNa 28 Cubesats NASA/Various LEO (Approx 400 x 400 km, 51.7°) 10-20 kg Various cubesats by a variety of universities and research groups. Will be deployed separately from ISS.

Mission success criteria

  • successful separation and deployment of Dragon into the target orbit
  • berthing to the ISS
  • unberthing from the ISS
  • reentry, splashdown and recovery of Dragon.

A+ report


There are studies saying micro-gravity could eliminate cancer cells. I think SpaceX is about to get very profitable.

SpaceX will make tons of money with space internet (StarLink). Imagine you can get fast internet anywhere in the world for a reasonable price! No more dealing with local internet provider bullshit.
They have the rockets and the funds to achieve it.

There is an interesting kurzgesagt video on cancer. It is only available in German, use subtitles auto translate.

I get your enthusiasm. However our near earth space being full of thousands of satellites doesn’t seem that great.

This will significantly improve lives of many people. Think about how GPS changed our lives.
Of course there are dangers. But near earth satellites will stay in orbit much shorter time if they stop working. They even have procedures to actively de-orbit them.
