Space Shuttle - STS 62 A Polar Express high altitude journey
GinGin » Thu Mar 18, 2021 10:46 pm
I decided to go for a long haul mission with saves and resumes to go through all the nominal operations that we can accomplish with the Shuttle.
Seeing the last screens from EatDirt and Thorsten, I wanted to go high both in inclination and in altitude, at the limits of what would have been the Vandenberg Department of Defense missions.
I chosed to try to replicate STS 62 - A, which would have been the first Polar Mission from Vandenberg in 1986.
Part 1: A tough journey began with thorough preparations ....

The Big Business Of Small Space Tech - Are We There Yet - Space


Phantom Space’s Jim Cantrell
Two private space companies developing small launchers made big announcements last week. Rocket Lab said it’s going public and unveiled a new rocket. 3D printing company Relativity Space unveiled plans for a second launch vehicle.
It’s a busy time for the small launch market. We’ll take a dive into the big business of small launchers with Anthony Colangelo, host off the Main Engine Cut Off podcast.
But first, small rockets launch small satellites. Engineer and entrepreneur Jim Cantrell wants to mass manufacture these satellites and build a rocket of his own with his new company Phantom Space. We’ll take a look at the emerging market and growing use cases for small, mass produced satellites and the customers driving the industry’s rapid development. ....

Second prevalve issue delays completion of SLS Core Stage Green Run campaign


Second prevalve issue delays completion of SLS Core Stage Green Run campaign
February 26, 2021
A problem with another one of the eight prevalves in the Artemis 1 Core Stage for NASA’s Space Launch System (SLS) has postponed a second test-firing to wrap up the Green Run campaign. The SLS Program’s first flight article has been installed in the B-2 Test Stand at the Stennis Space Center in southern Mississippi since January 2020.
After a liquid hydrogen prevalve was repaired in November, all the prevalves worked during tanking and firing tests until final preparations for a second Hot-Fire when a liquid oxygen prevalve stopped opening correctly. Engineers are back inside the stage’s engine section to troubleshoot the failure and determine what needs to be fixed; currently, NASA doesn’t expect to be ready to test-fire the stage again until mid-March. ....
