Blue Origin founder Jeff Bezos hinted that tests of the company’s BE-4 engine will start soon.

Bezos, in an email update Monday on the company’s work on the engine, said he’ll provide more news as the testing of the BE-4 “progresses in the coming weeks.”

The company released images earlier this month of the first completed engine, which Bezos said was being prepared for shipment to the company’s West Texas test site.

Bezos, in the email update, primarily discussed the design of hydrostatic bearings used in the engine’s turbopump. [GeekWire]

North Korea says it has tested a new rocket engine it claims could be used to support its space program. State media announced over the weekend the successful test of the engine, saying it supports the development of future satellite launch vehicles. While many Western observers believe the test is linked to the country’s development of long-range ballistic missiles, at least one expert notes the engine doesn’t appear to be a good fit for any known North Korea missile programs, and instead may be for the second stage of a proposed launch vehicle.

NASA is not tweeting as much about its “Journey to Mars” these days. In the first two months of the Trump administration, NASA used the #JourneyToMars hashtag just once in its tweets from its flagship @NASA account, compared to an average of six times a month in the last half-year of the Obama administration. A NASA spokesman said the lack of use of the hashtag was not a deliberate decision reflecting a change in policy, noting that other NASA social media accounts have used it and that, in general, hashtags are not as effective in social media as they once were.
