In new Starship details, Musk reveals a more practical approach

For example, Musk said, “Initially making one 200 metric ton thrust engine common across ship & booster to reach the Moon as fast as possible. Next versions will split to vacuum-optimized (380+ sec Isp) & sea-level thrust optimized (~250 ton).”

This comment is notable for a couple of reasons. First of all, the company appears to have decided to streamline the Raptor engine to a single design that will power both the rocket at liftoff, and the spaceship in the upper atmosphere and outer space. It will take less time to develop, test, and qualify a single engine. It will also cost less money.

Additionally, Musk notes that the goal is “to reach the Moon as fast as possible.” The company still appears to be focused on lunar orbital flights, such as the #dearMoon project for Japanese businessman Yusaku Maezawa, as the first missions for Starship.

Blue Origin breaks ground for BE-4 factory

WASHINGTON — As Blue Origin breaks ground on a new factory for producing rocket engines, the company says development of its BE-4 engine will be completed later this year.

Blue Origin held a groundbreaking ceremony in Huntsville, Alabama, Jan. 25 to formally mark the start of construction of a factory that will be used for building BE-4 engines. The company announced plans to build the factory there in June 2017, contingent on the selection of the engine by United Launch Alliance for its Vulcan rocket. ULA picked the BE-4 in September 2018.

The factory, scheduled for completion in March 2020, will build dozens of BE-4 engines a year for both Vulcan as well as Blue Origin’s own New Glenn vehicle. Both rockets are scheduled to make first launches in 2021. Vulcan will use two BE-4 engines in its first stage while New Glenn’s reusable first stage will be powered by seven BE-4 engines.

NASA: Astronaut immune system cells affected by long-term trips

NK-cell function appears to be impaired during spaceflights over long durations according to a new study published this week. This means that immune systems could be broken down somewhat during the long trips NASA hopes to take with astronauts in the distant future. The research here was done by a team of researchers at the University of Arizona, the University of Houston, Louisiana State University, and NASA-Johnson Space Center.

Trump reportedly offered NASA ‘all the money you could ever need’ to land on Mars during his presidency

Some people on his communications staff at the time were not pleased.

Sims writes that he was “getting antsy” in the room due to Trump’s abrupt question shortly before a televised phone call with the Space Station. NASA officials were believed to have gone to great lengths to coordinate with the Space Station, which could only be reached during a certain time due to “orbital mechanics.”

“All I could think about was that we had to be on camera in three minutes … And yet we’re in here casually chatting about shaving a full decade off NASA’s timetable for sending a manned flight to Mars,” Sims reportedly wrote. “And seemingly out of nowhere.”

Trump, who appeared “distracted,” reportedly asked Lightfoot: “But what if I gave you all the money you could ever need to do it?”
