NASA may have sidelined the Lunar Gateway for a return mission to the Moon, but it is not stopping the momentum. NASA has awarded several contracts for the Lunar Gateway including the most recent one to SpaceX. This demonstrates the growing capabilities of New Space companies to capture contracts and complete missions.

This contract award is another critical piece of our plan to return to the Moon sustainably. The Gateway is the cornerstone of the long-term Artemis architecture and this deep space commercial cargo capability integrates yet another American industry partner into our plans for human exploration at the Moon in preparation for a future mission to Mars.NASA Administrator Jim Bridenstine in a press release statement about the award to SpaceX.

NASA Awarded SpaceX the first Artemis Gateway Logistics Services (GLS) contract. The award for resupply services to the Gateway will require delivery of goods to a Near Rectilinear Halo Orbit (NRHO). Not sure what a NRHO orbit is? A NRHO is a highly elliptical orbit that takes about 7 days for each orbit. Want some more details, just click here: Near Rectilinear Halo Orbit (NRHO). There are a few options for NRHO orbits, but NASA is leaning towards the L2 9:2 lunar synodic resonant southerly Near-Rectilinear Halo Orbit (NRHO) which would be the likely location of the lunar Gateway. A simplification of the orbit is shown below.

Part 2 of the Life in Space with COVID19 we will delve into Crew demo-2 where NASA and SpaceX are planning a launch within two months. There are a lot of pre-launch milestones and activities to cover to ensure a safe flight for the Astronauts. If anything goes wrong, there are lives at stake. Now NASA and SpaceX have to contend with another potential setback, COVID19 pandemic. (Click here for part I)

In Part I of why COVID19 pandemic is bad timing for the Space industry, we covered that issues happen because the relationship between complexity, risk, schedule and cost for space missions was not balanced.

SpaceX just launched a Hyperloop pod-racing competition By Sean O’Kane | The Verge

Posted by in categories: business, sustainability, transportation

“SpaceX just announced an official contest open to university students and independent engineering teams. The company will release detailed rules, criteria, and tube specifications in August. … The challenge will be to build “human-scale pods” to be tested on the Hawthorne, California test track that will be built next to the SpaceX headquarters, but the company is careful to note that no humans will ride in the pods. All the designs submitted must be open source.”

SpaceX’s Success

Posted by in categories: complex systems, disruptive technology, engineering, innovation, space, space travel

I read all the news about SpaceX’s Falcon 9 latest “failure” to land on an autonomous spaceport drone ship aka barge. I view these as trials to success. Here’s why.

1. Grasshopper Successes: The two videos below show that the early landing trials aka Grasshopper from several heights between 250m and 1,000m.

The lessons here are:

a) Pinpoint landing of a 1st stage rocket is technologically feasible.

The Realistic Cost Of The Next Space Race

Posted by in categories: business, economics, engineering, finance, hardware, innovation, policy, space, space travel

Based on the Bloomberg TV program “The Next Space Race” and other reliable sources, I determine the realistic payload costs goals for the next generation of private space companies.

I review NASA’s Space Shuttle Program costs and compare these with SpaceX costs, and then extrapolate to Planetary Resources, Inc.‘s cost structure.

Three important conclusions are derived. And for those viewing this video at my blog postings, the link to the Excel Spreadsheet is here (.xlsx file).

The Next Space Race

Posted by in categories: engineering, finance, innovation, physics, science, space, space travel

Yesterday’s program, The Next Space Race, on Bloomberg TV was an excellent introduction to the commercial aerospace companies, SpaceX, the Sierra Nevada Company (SNC), and Boeing. The following are important points, at the stated times, in the program:

0.33 mins: The cost of space travel has clipped our wings.
5:18 mins: How many people knew Google before they started?
7:40 mins: SpaceX costs, full compliment, 4x per year at $20 million per astronaut.
11:59 mins: Noisy rocket launch, notice also the length of the hot exhaust is several times the length of the rocket.
12:31 mins: One small step for man, one giant leap for mankind.
12:37 mins: Noisy shuttle launch, notice also the length of the hot exhaust is several times the length of the rocket.
13:47 mins: OPF-3, at one time the largest building in the world at 129 million cubic feet.
16:04 mins: States are luring private companies to start up in their states.
16:32 mins: NASA should be spending its money on exploration and missions and not maintenance and operations.
17:12 mins: The fair market value of OPF-3 is about $13.5 million.
17:19 mins: Maintenance cost is $100,000 per month
17:47 mins: Why Florida?
18:55 mins: International Space Station (ISS) cost $60B and if including the Shuttle program, it cost $150B.
19:17 mins: The size of the commercial space launch business.
21:04 mins: Elon Musk has put $100 million of his own money into SpaceX.
21:23 mins: The goals of NASA and private space do not conflict.

Summary:
1. Cost of ISS is $60B, total cost including the Shuttle program is $150B.

2. SpaceX cost is $20M per astronaut (for 7 astronauts) or a launch cost of $140 million per launch at $560 million per year for 4 launches per year.
