![]() ![]() What is this going to be like?,” he says. “We had never been on a zero-G flight before, so it was the usual nervousness going in. Ron Stephens stood on the tarmac in Ottawa alongside NASA researchers, trying to pretend like he wasn’t nervous about boarding a test aircraft that would repeatedly climb high into the sky and then nosedive towards earth, creating the zero-gravity conditions he needed to test his space printer. #NO GRAVITY ROOM SOFTWARE#The facility was designated a National Historic Landmark in 1985 for its role in the early space program.Artificial Intelligence (802) Auto Tech (31) Blockchain (149) CanadianCIO (81) Careers & Education (4411) Channel Strategy (22) Cloud (1994) Communications & Telecom (329) Companies (648) Data & Analytics (1244) Development (639) Digital Transformation (1149) Distribution (123) Diversity & Inclusion (39) Ecommerce (81) Emerging Tech (24132) End User Hardware (28) Engineering (79) Financial (104) FinTech (78) Future of Work (312) Governance (92) Government & Public Sector (5979) Human Resources (800) Infrastructure (8488) IoT (6164) ITWC Morning Briefing (107) Leadership (4254) Legal (110) Legislation (120) Managed Services & Outsourcing (4302) Marketing (53) MarTech (3) Medical (18) Mobility (3415) Not For Profit (13) Open Source (24) Operations (67) People (95) Podcasts (1898) Privacy (575) Project Management (1099) Security (7482) Service (38) Smart Home (15) SMB (49) smb-leadership (1) Social Networks (142) Software (4125) Supply Chain (107) Sustainability (71) Tech in Sports (4) Women in Tech (167) In order to ensure proper firing and functioning of upper-stage rockets, NASA needed to understand the behavior of fluids (importantly, the liquid gases fueling the rockets), in the reduced gravity where they would fire. The Zero Gravity Research Facility was built in 1966 as part of NASA's Centaur upper-stage rocket development program. Tests are conducted from the control room, which contains controls for the "pump down" of the vacuum chamber, the experiment vehicle pre-drop checkout, release and the data retrieval system. Assembly, servicing, and balancing of the experiment vehicle are accomplished in the shop area. The service building at the top of the shaft contains a shop area, control room, and a clean room. ![]() Equipment dropped in the chamber experiences microgravity for about 5.15 seconds before landing in a deceleration cart filled with expanded styrofoam beads it typically experiences 32g during deceleration, but may range up to 65g. Test equipment is typically mounted in a cylindrical container, and has a maximum weight of 2,500 pounds (1,100 kg). The pressure in this vacuum chamber is reduced to 13.3 pascals (1.3 ×10 −4 atm) before use. ![]() A steel vacuum chamber, 20 feet (6.1 m) in diameter and 470 feet (140 m) high, is contained within the concrete shaft. The facility consists of a concrete-lined shaft, 28 feet (8.5 m) in diameter, that extends 510 feet (160 m) below ground level. The facility uses vertical drop tests in a vacuum chamber to investigate the behavior of components, systems, liquids, gases, and combustion in such circumstances. ![]() It has successfully supported research for the United States crewed spacecraft programs and numerous uncrewed projects. The Zero Gravity Research Facility at the NASA Glenn Research Center in Cleveland, Ohio is a unique facility designed to perform tests in a reduced gravity environment. ![]()
