Jeff Bezos Muses About Those Underappreciated Engine Components – Bearings

By Jeff Bezos

Although the BE-4 turbopump is smaller than your refrigerator, it generates 70,000 horsepower from a turbine running at nearly 19,000 revolutions per minute that pumps cryogenic propellants to pressures just under 5,000 pounds per square inch. To react the forces generated by the rotating turbine and impellers inside the pump, production rocket turbopumps to date have used traditional ball and roller bearings. For BE-4, we’re doing something different – we’re using hydrostatic bearings.

Bezos Provides More Details on New Glenn

Jeff Bezos unveiled a video simulation of a New Glenn launch (above) at the Satellite 2017 conference in Washington, DC, this morning. He revealed that Eutelsat is the first customer to sign up for a launch.

The booster is designed to lift 45 tons to low Earth orbit and 13 tons to geosynchronous transfer orbit. The first stage is also designed to be launched 100 times. It will have six landing legs.

I had hoped he would reveal something of his lunar delivery service plan that is circulating among policy makers in Washington, But, Bezos said not a word about it.

Bezos to Reveal Something on Tuesday

Blue Origin’s Jeff Bezos is expected to announce something on Tuesday in a speech at the Satellite 2017 conference in Washington, DC.

I’m guessing it will be an elaboration on the company’s plans for establishing a base at the south pole of the moon. He also will likely provide updates on the testing schedule for the BE-4 engines (pictured above), development of the New Glenn booster, and construction of the company’s manufacturing facility in Florida.

The Year Ahead in Space

It’s going to be busy year in space in 2017. Here’s a look at what we can expect over the next 12 months.

A New Direction for NASA?

NASA’s focus under the Obama Administration has been to try to commercialize Earth orbit while creating a foundation that would allow the space agency to send astronauts to Mars in the 2030’s.

Whether Mars will remain a priority under the incoming Trump Administration remains to be seen. There is a possibility Trump will refocus the space agency on lunar missions instead.

Rep. Jim Bridenstine (R-OK), who is currently viewed as a leading candidate for NASA administrator, has written two blog posts focused on the importance of exploring the moon and developing its resources. Of course, whether Bridenstine will get NASA’s top job is unclear at this time.

President elect Donald Trump has named commercial space backer Charles Miller to the NASA landing team amid reports that similar minded advocates will be added to transition group.

Miller is president of NexGen Space LLC, a company that advises clients on commercial, civil and national security space.  He previously served as NASA’s senior advisor for commercial space.

The Wall Street Journal reports that Trump officials are also working on appointing Alan Stern, chairman of the Commercial Spaceflight Federation, and Alan Lindenmoyer, who formerly managed NASA’s Commercial Crew and Cargo Program. Both nominations are in the process of being vetted for conflicts of interest.

Just a very short note to update you on the 750,000 square-foot New Glenn rocket factory we’re building in Florida. The team has made extraordinary progress—as you can see here, the first steel is now going up.

And again, here’s an image of what it will look like by the end of 2017.

NASA and various commercial companies gave updates on their programs during the International Symposium on Commercial and Personal Spaceflight this week in Las Cruces, NM.

What follows are summaries that include:

  • suborbital programs (Virgin Galactic, Blue Origin)
  • commercial cargo (SpaceX, Sierra Nevada Corporation)
  • commercial crew (NASA, Boeing, ULA).

The summaries are based on Twitter posts from attendees. A big thanks to Thanks to Tanya Harrison (‏@tanyaofmars), Frank Slazer ‏(@FSlazer), Jeff Foust (‏@jeff_foust), Michael Simpson ‏(@SpaceSharer), and Melissa Sampson (‏@DrSampson) for the coverage.
