Speaker: Richard Campbell
- Talked about the billionaires going to space vanity projects
- Can do freefall for less money
- New Sheppard went off path and ignored request to go back on track
- Will launch majority of commercial payloads this year.
- Drives down price be recovering a stage
- New contracts incentives traveling often
- Blue Origin working on Blue Glenn – longer rocket. Nobody has seen anything yet. Like a bigger version of Falcon. But a big jump from New Sheppard.
- SLS (Space Launch System) attempts to make a rocket out of other parts. Might fly this year. Targets the moon. Congress keeps paying for.
- Starship (from Elon Musk). Pieces of it exists. Does R&D in public with youtube watching. Bigger than Saturn V, but both stages recoverable
- In an airplane, 60% is airplane. In spaceship, only 2%. Most is payload and fuel.
- That’s why it hasn’t been as bad to “fly it once and throw away the airplane”
- If Starship is successful, reduces cost because fully reusable. Paying for fuel and maintenance. But speculative because doesn’t exist yet. If can do it, costs about the same as a first class airline ticket to go to space.
- ISS (international space station) – mismatch of things. Old. Will end sometime in our lifetime. Originally planned to end in 2020. Now proposals through 2030.
- Bigalow Aerospace working on inflatable materials to create durable materials and assemble in space. Can connect modules together to build a space station. Three modules would be larger in volume than ISS. Proposed replacing oldest module (Russian one) with inflatable one.
- Axiom – group of former space station technicians that want to build own space station. Have contract with NASA to build tourism attachments to ISS. Need more money, but raising more.
- Apollo was a military mission (competition between US and Soviet Union)
- Were supposed to be 20 missions but cancelled because dangerous
- Sent one geologist on Apollo 17 (rest military)
- NASA wants to build an autonomous space station in orbit around the moon.
- Can’t leave pieces of the craft each time land.
- Can’t kneel in a space shoot
- All solutions require some assembly in orbit
- Margin of error for landings on the moon is 1km.
- Moon gravity is irregular – up to 2% distortion. (an inch a second faster or slower.) Think based on craters/impact
Problem in space
- Fluid builds in face because no gravity. Need glasses even if perfect vision because eye shape changes
- Get weak even if exercise
- Bottom of feet hurt from lack of use
- Need centrifuge
- Need giant centrifuge for 1G because need gravity and feet to be similar so don’t get sick
- Can do an experiment with extended lower gravity on moon to see what need to travel to Mars
- Everything to date has been camping trip where bring everything yu need and take everything back with you
This was a fun end to the day! Excellent pictures and stories.
