What is the Fluidic Telescope?
FLUTE aims to find out if giant lenses and mirrors – the high-quality optical components needed for future large-aperture space telescopes – can be created from liquids in space. The Fluidic Telescope (FLUTE) project team, jointly led by NASA and…
Shrinking Reservoirs in Catalonia
Heat and drought have parched reservoirs in northeastern Spain.
New Transient Finite Energy Shock Prediction Methodology
In a major departure from prior methodologies, a physics-based shock prediction method has been created, executed, and compared against test results. Traditionally, shock response spectra (SRS) prediction has been extremely challenging.
NDE Survey Examines the Origin of Detectable Flaw Sizes Used in Spacecraft Hardware
The NDE and structures communities rely on NASA Standard 5009B, where the NDE detection capability requirements can be found for NASA systems or components that are considered fracture critical.
The 2022 GNC Discipline Year in Review
The NESC GNC Technical Discipline Team (TDT) conducted numerous activities in the course of 2022 in support of the NASA Mission Directorates. Discussed below are three noteworthy highlights and a look into the future of the GNC discipline at NASA.
Re-Architecting the NASA Wire Derating Approach
Exceeding the wire temperature rating can result in electrical, physical, and/or chemical degradation of the wiring insulation and conductor, which could lead to a catastrophic failure.
I Am Artemis: Mark Wagner
As Gateway’s baseline verification, assembly, and integration team lead, Wagner and his group test the core functions of Gateway’s I-Hab (International Habitation Module), one of two modules where Artemis crew will live and work, to ensure that I-Hab is equipped…
NESC Helps Fill Gaps in Propulsion Knowledge
After 22 years, Dr. Daniel Dorney, the NASA Technical Fellow for Propulsion, retired in August. Before he left, he reflected on a few of the more than 30 propulsion-related activities he led for the NESC and how expanding NASA’s propulsion…
How Do We Sustain Human Exploration in the Artemis Era?
Planning is underway at NASA for returning humans to the Moon, followed by human missions to Mars. Astronauts will again venture outside the protective shield of the Earth’s magnetosphere, this time for durations of months to years, where they will…
55 Years Ago: NASA Administrator Webb OKs Flying a Crew on the Third Saturn V
April 1968. With the end-of-the-decade deadline set by President John F. Kennedy during his May 25, 1961, address to Congress of landing a man on the Moon and returning him safely to the Earth, fast approaching, senior NASA managers needed…
NASA’s Quesst: Reassessing a 50-Year Supersonic Speed Limit
NASA will deliver the results to U.S. and international regulators, who will consider new rules that would lift the ban that has been in place for so long.
Amendment 20: E.6 Fundamental Physics Not Solicited This Year
1 min read Amendment 20: E.6 Fundamental Physics Not Solicited This Year When it is solicited, E.6 Fundamental Physics identifies and develops concepts for transformative applications of the space environment to advance the boundaries of experimental physics via experiments uniquely…
Amendment 19: B.5 Living with a Star Science Final Text and Due Dates
1 min read Amendment 19: B.5 Living with a Star Science Final Text and Due Dates The goal B.5 Living with a Star Science (LWS) is to provide advances in scientific understanding of the coupled Sun-Earth system that can lead…
Ensuring Robotic Arm Safety During Abrasions
This past week, the Perseverance rover has driven to a rock outcrop called Echo Creek, situating itself just west of the Belva crater rim peppered with large flagstone rocks suitable for its next task: abrasion.
Nearly 23,000 Acres Designated for NASA Satellite Calibration
The Bureau of Land Management has approved NASA’s request to withdraw 22,634 acres of land in Railroad Valley (RRV), Nevada, from public and private use, preserving the land for a 20-year period for calibrating Earth-observing satellites.
NASA Tests Critical In-Flight Capability During RS-25 Engine Hot Fire
NASA carried out a critical hot fire of the redesigned RS-25 engine April 26 at NASA’s Stennis Space Center in Bay St. Louis, Mississippi, demonstrating the gimbaling, or pivoting, capabilities needed to stabilize a rocket during a launch and flight…
