NASA Celebrates Ames’s Legacy of Research on National Aviation Day

NASA works every day to improve air travel – and has been doing so since its creation decades ago. On National Aviation Day, NASA and all fans of aviation get the chance to celebrate the innovative research and development the agency has produced to improve capability and safety in flight.

NASA’s Ames Research Center in California’s Silicon Valley has a historic legacy in aeronautics research. When the center was founded in 1939 by the National Advisory Committee for Aeronautics (NACA), its early research included working to reduce icing on aircraft wings.

When ice coats the wings of an airplane, it reduces lift and increases drag, which can cause the aircraft to lose altitude and control. Ames researchers developed different approaches to solve the icing challenge, including a “hot wing” thermal anti-icing system. The system worked by running hot engine exhaust along the leading edges of aircraft wings, warming them and preventing ice buildup. Ames researchers modified aircraft and tested them before traveling to Minnesota, where they were flown in icy conditions.

Today, many turbine-powered aircraft, like passenger jets, use “bleed air” anti-icing systems, which warm the leading edges of aircraft wings using compressed air from their engines. These systems are built upon the early research and testing done at Ames.

The legacy of aviation innovation continues at Ames, through aeroscience research like wind tunnel testing, air traffic management, and advanced aircraft systems.

Station Science Top News: August 16, 2024

Locations designed as a maintenance work area and an exercise area on the International Space Station are commonly used by crew members for stowage and body maintenance activities, respectively. These differences between intended and actual use demonstrate that systematic observation of material culture can help researchers identify how astronauts adapt to life in microgravity and support better design of future spacecraft and habitats.

The first archaeological fieldwork in space, SQuARE examined the space station’s material culture – objects and built spaces and their symbolic and social meanings – and how these objects and spaces are used over time. Results suggest that more flexible definitions of use of spaces could improve crew autonomy and enable broader use of all areas by the entire crew. The researchers also found a significant number of adhesives and ties are used to keep objects from floating away, suggesting this is a critical adaptation crews must make in microgravity and that these gravity surrogates could be optimized for future space habitats.

Analysis of XMM-Newton, Chandra, and NICER (Neutron star Interior Composition Explorer) observations of seven thermally emitting isolated neutron stars (XINS) in the constellation Canis Major showed erratic spin behavior in one of them (RX J0720.4−3125).  This behavior hints at complex surface heat distribution, a feature usually associated with a strongly magnetized atmospheric layer. The finding could lead to an improved understanding of the neutron star population in our galaxy and of neutron star evolution.

NICER makes high-precision measurements of X-ray astrophysics phenomena such as neutron stars, the ultra-dense matter created when massive stars explode as supernovas. XINSs likely represent a significant fraction of all neutron stars, but their origin and evolutionary history are uncertain. Researchers plan to use detailed modeling of the extensive NICER dataset to fully map temperature distribution on the surface of these stars, which could reveal the underlying physical processes responsible for their peculiar properties.

Researchers demonstrated the feasibility of using an engineered human tissue model to screen drugs for treating impaired muscle regeneration in astronauts and patients on Earth.

Muscle mass diminishes with age on Earth and astronauts experience similar but accelerated loss of muscle mass during spaceflight. Cardinal Muscle evaluated engineered human muscle cells cultured in microgravity as a model for studying muscle loss and treatment.

Researchers found that the model mimicked impaired muscle regeneration after just seven days in microgravity and that two drugs, insulin-like growth factor-1 (IGF-1) and a 15-hydroxyprostaglandin dehydrogenase inhibitor (15-PGDH-i), partially inhibited microgravity’s effects on the engineered tissue.

Sols 4277-4279: Getting Ready To Say Goodbye to the King!

Earth planning date: Friday, Aug. 16, 2024

It’s time to move on from our “Kings Canyon” drill site, so today’s plan focused on our usual tidy up routine after a drill campaign. First we need to dump out any material in the drill chambers, in an action called “RAGE” – this sounds aggressive but stands for “Rotation to Agitate Granules for Expulsion,” so it’s more of a gentle turning than an angry shaking. This ensures that the drill chambers won’t spill later and we are ready for the next drill campaign – whenever we find a worthy target! Mastcam will document the entire process, and then image the drill bit that was used, making sure it is still in good condition.

At that point, we are free to use the arm instruments again (no turret movements allowed while there is sample in the drill chamber). So our contact science focuses today on the drill tailings, the pile of ground up rock generated by the drill action. That pile has been sitting there for over two weeks, but luckily it’s not too windy right now and the pile remained more or less intact. MAHLI will image the drill hole and the tailings pile on the first afternoon, APXS will integrate on the tailings on the first night and then MAHLI will image the tailings again on the second day. This post-retract image is just to confirm that APXS did not hit the pile of loose drill fines. As APXS Science Planner today, I worked with RPs to pick out the spot we will focus on and to make sure that we are using the correct sequences to ensure safety of the instrument – but it’s always nice to confirm that we didn’t hit the pile!

ChemCam has a suite of activities, from LIBS activities close to the rover, to “passive” (non destructive) activities and RMI images (which can be relatively near field or long distance). LIBS on the bedrock target “Marck Lake” will be used to compared with the nearby Kings Canyon target and assess homogeneity across the drill block, while the passive observation of “Red Slate Mountain” will examine a large light toned block about 10 metres away from the rover. ChemCam will also acquire a long distance RMI of loose blocks and boulders about 85 metres away, looking towards “Milestone Peak” (shown in the accompanying image).

APXS will acquire an overnight “atmospheric” measurement, looking at levels of argon as part of an ongoing campaign. This is paired with ChemCam’s second passive measurement, this time of the sky. We also have monitoring of dust levels, with Mastcam taus of the atmosphere (which atmospheric scientist Alex Innanen talked about here), and a whole host of Navcam dust devil movies, and suprahorizon and zenith movies (which target different parts of the horizon). All of these … and DAN and REMS activities too – our environmental monitoring team is working hard as usual!

ChemCam has spent the last two weeks or so getting LIBS and passive measurements on “Sam Mack Meadow” – an area of darker toned, sometimes broken up rocks just outside of the current workspace. In fact, ChemCam is getting LIBS on two further targets there in this plan: “Horse Creek Spire” and the somewhat nodular “Kearsarge Pinnacles.” Mastcam will image all of the LIBS targets too. There are some interesting textures here that APXS and MAHLI are keen to sample too, so our next drive is more of a bump to get close enough to allow contact science here too. We will still be able to gaze on the King (Canyon) for another while, so I guess it’s not really goodbye just yet!

Hubble Spots Billowing Bubbles of Stellar Floss

A bubbling region of stars both old and new lies some 160,000 light-years away in the constellation Dorado. This complex cluster of emission nebulae is known as N11, and was discovered by American astronomer and NASA astronaut Karl Gordon Henize in 1956. NASA’s Hubble Space Telescope brings a new image of the cluster in the Large Magellanic Cloud (LMC), a nearby dwarf galaxy orbiting the Milky Way.

About 1,000 light-years across, N11’s sprawling filaments weave stellar matter in and out of each other like sparkling candy floss. These cotton-spun clouds of gas are ionized by a burgeoning host of young and massive stars, giving the complex a cherry-pink appearance. Throughout N11, colossal cavities burst from the fog. These bubbles formed as a result of the vigorous emergence and death of stars contained in the nebulae. Their stellar winds and supernovae carved the surrounding area into shells of gas and dust.

N11’s stellar activity caught the attention of many astronomers, as it is one of the largest and most energetic regions in the LMC. To investigate the distribution of stars in N11, scientists used Hubble’s Advanced Camera for Surveys, taking advantage of its sensitivity and excellent wide-field resolution. The cluster houses a wide array of stars for Hubble to examine, including one area that has stopped forming stars, and another that continues to form them. Hubble’s unique capabilities allowed astronomers to comprehensively study the diversity of stars in the N11 complex, and map the differences between each region.
