A selection of recent items related to space access:
** ISRO flew the latest version of the PSLV (Polar Satellite Launch Vehicle) launched on Thursday and put a military spysat (Microsat-R) and a student developed technology demo spacecraft (Kalamsat-V2) successfully into orbit:
- PSLV-C44 successfully launched Microsat-R and Kalamsat-V2 – ISRO

- PSLV launches debut orbital platform use of the fourth stage – NASASpaceFlight.com
** Scott Manley gives a
round up of big space news stories, with Blue Origin flying its first commercial mission while Elon Musk Starship Hopper falls over in high winds. We also got the details on why building the Super Heavy Booster from stainless steel was ‘counter intuitive. Stratolaunch’s Roc looks like it’s becoming the modern equivalent of the Spruce Goose and Vector Space Systems gears up for a test launch.
** Blue Origin released these videos following this week’s successful New Shepard flight:
We have a lean and mighty team in mission control on launch day – about 30 people who operate New Shepard. Meet our teammate Laura who, like all of us at Blue, is focused on lowering the cost of access to space.
New Shepard’s reusability is lowering launch costs and creating routine access to space. Lowering the cost of microgravity research increases the opportunities for universities, government researchers and entrepreneurs to test payloads and technologies in space.
When we delivered New Shepard PM 4 to our West Texas launch site in December, it was the first time we had two rockets in the barn in Texas. We’re building our fleet of versatile reusable launch vehicles step-by-step as we move towards operations.
Blue Origin demonstrated the versatility of the New Shepard system by taking 8 NASA-sponsored research and technology payloads into space today.
** SpaceX:
*** A pad test firing was carried out at Cape Kennedy on Jan.24th of the Falcon 9 that is to send the first Dragon-2 vehicle to dock with the ISS. The demo mission, which will have no astronauts on board, is currently expected to happen sometime in the second half of February.

** Tom Mueller, head of SpaceX propulsion since the founding of the company, reviews the history of the Merlin engine, which powers both stages of the Falcon 9 rocket. He was accepting an award from the National Space Society at the NSS’s annual ISDC meeting last May. (Mueller’s comments start at 5:25):
