    American Museum Of Natural History

    Explore The Arthur Ross Hall Of Meteorites

    Published 9th November 2019

    As the Earth rotates around the Sun, rock fragments enter our atmosphere and fall to the surface where we can collect them as meteorites. What can we learn from these space rocks? They hold data about the formation of the solar system and planets. Curator in the Division of Physical Sciences Denton Ebel takes us on a tour of the Arthur Ross Hall of Meteorites at the American Museum of Natural History where we can explore the origins of the solar system and planets, learn about sample-return missions, and delve into hazards posed by meteorite impacts.

    Space-Grade CPUs: How Do You Send More Computing Power Into Space?

    Published 11th November 2019



    Phobos-Grunt, perhaps the most ambitious deep space mission ever attempted by Russia, crashed down into the ocean at the beginning of 2012. The spacecraft was supposed to land on the battered Martian moon Phobos, gather soil samples, and get them back to Earth. Instead, it ended up helplessly drifting in Low Earth Orbit (LEO) for a few weeks because its onboard computer crashed just before it could fire the engines to send the spacecraft on its way to Mars.

    In the ensuing report, Russian authorities blamed heavy charged particles in galactic cosmic rays that hit the SRAM chips and led to a latch-up, a chip failure resulting from excessive current passing through. To deal with this latch-up, two processors working in the Phobos-Grunt’s TsVM22 computer initiated a reboot. After rebooting, the probe then went into a safe mode and awaited instructions from ground control. Unfortunately, those instructions never arrived.

    Stingray-Inspired Spacecraft Aims To Explore Dark Side Of Venus

    Published 11th November 2019



    Venus is Earth’s neighbor, yet scientists’ understanding of the planet is relatively limited, especially on the so-called “dark side.”

    That knowledge gap may eventually be filled because University at Buffalo researchers are designing a unique spacecraft for NASA that might explore the planet like no previous probe.

    The Bio-inspired Ray for Extreme Environments and Zonal Explorations (BREEZE) project is one of 12 revolutionary concepts selected by NASA for its Innovative Advanced Concepts (NIAC) program, which funds early-stage technologies that could change what’s possible in space. (Six other projects chosen in previous years received additional funding.)

    Proposed by the university’s Crashworthiness for Aerospace Structures and Hybrids (CRASH) Laboratory, researchers envision a morphing spacecraft with wings that flap like a stingray’s pectoral fins. The design could make efficient use of high winds in the planet’s upper atmosphere while providing scientists unparalleled control of the vehicle.

    Does Life Need A Multiverse To Exist?

    Published 11th November 2019

    Life exists in our universe. There we go - one hopefully uncontroversial statement. Therefore our universe is capable of producing and supporting life. How am I going? Two for two? Let’s try for three: therefore there are countless universes. Hmmm. Did I break my streak?

    Our universe seems to operate according to a set of fundamental rules that we try to understand and model with the equations of our laws of physics. Those equations always include one or more fundamental constants - simple numbers that set the scale for the equation. We can’t determine the values of these constants from pure theory - we have to measure them in the real universe. These are things like the speed of light, the Planck constant, the masses of the elementary particles, and the constants defining the relative strengths of the fundamental forces - the so-called coupling constants.

    With Mars Methane Mystery Unsolved, Curiosity Serves Scientists a New One: Oxygen

    For the first time in the history of space exploration, scientists have measured the seasonal changes in the gases that fill the air directly above the surface of Gale Crater on Mars. As a result, they noticed something baffling: oxygen, the gas many Earth creatures use to breathe, behaves in a way that so far scientists cannot explain through any known chemical processes.

    How Close Are We To Terraforming Mars?

    Published 13th November 2019



    There have been some wild proposals about how to make Mars more suitable for humans—but how close are we to actually terraforming the Red Planet?

    A term originally coined in science fiction, terraforming, in basic terms, is changing the atmosphere and climate of a planet so it can support human life without the need for equipment like spacesuits.

    In order to survive on Mars, we would need to be able to do a few basic things: breathe, stay conscious, not freeze to death, and over time grow food.

    Right now, if humans were to step outside while on Mars, we’d pass out instantly and die pretty soon after as a result of the low pressure pulling oxygen out of solution in our blood.

    Doesn’t sound too habitable, huh?

    But if we could find a way to thicken the atmosphere by adding mass to it, the result might be kickstarting a greenhouse effect that would stabilize the temperature, staving off some radiation, too.

    To achieve this level of climate alteration, we would need to build hundreds of factories on Mars’ surface…and that is no small task.

    But with interest in space exploration and tourism on the rise, we might get the tools and tech we need sooner than we’d imagined.

    Find out more about what we would need to do to make Mars habitable for humans and how close we are to terraforming the planet on this episode of How Close Are We?

    As an alternative, what Wordsworth et al. suggest is a kind of localized 'farming' approach. Silica aerogel is extremely low density and porous, but it can also produce a solid-state greenhouse effect because it's fairly opaque to infrared radiation (and doesn't conduct heat well) but is partially transparent to visible and shorter wavelength light.

    The absence of water makes the temperature on Mars change a lot. The Mars exploration rovers (Spirit at Gusev Crater and Opportunity at Meridiani Planun) experienced temperatures ranging from a few degrees Celsius above zero to minus 80℃ at night: every single Martian day, known as sol.

    High Altitude Observatory

    Dana Lacatus | Spectroscopic Investigation Of The Solar Atmosphere

    Recorded & Published 13th November 2019

    The solar chromosphere plays a critical role in most of the open questions of solar physics, from coronal heating to the acceleration of the solar wind. It spans only 2000 km, but nine pressure scale heights, while the temperature increases by some two orders of magnitude. This layer is the location of most of the solar radiative losses, with the emission dominated by singly ionized ions. Despite its modest dimensions, the plasma properties make interpretation challenging, because most lines originating here are optically thick and formed in non-LTE.

    We present an exploration of the chromospheric emission, from quiet to flaring solar conditions, using spectroscopic data from the IRIS instrument. The main focus of this study is the variability of the Mg II resonance lines, investigating how their profiles change based on the emitting solar structure. The extraction of the different spectral features from the observed emission profile is detailed and general trends are discussed.

    Using quiet sun datasets we investigate potential characteristics that provide better contrast for distinguishing Coronal Holes from quiet sun in chromospheric emission. Thus we explore if any profile feature is more sensitive to the slightly different magnetic morphology, given that coronal holes are dominated by open field lines contributing to the solar wind acceleration.

    We also explore the enhanced emission and wide variation of profiles in more active conditions leading up, during, and after a strong solar flare. For a complete picture of the flaring event, we also include information covering the surrounding solar atmosphere, using data from IRIS, SDO, and RHESSI. The slow rise and eventual destabilization of a filament is found to be preceding the flare. In the descending phase of the flare, we identified an extended coronal rain episode that persisted for more than an hour and was characterized by peculiarly wide profiles in both chromospheric and TR emission lines.

    On 12 November 2014 Philae became the first spacecraft to land on a comet as part of the successful Rosetta mission to study comet 67P. Five years later, and after the mission’s official end in 2016, Rosetta is continuing to provide insights into the origins of our Solar System.

    Rosetta’s instruments have already discovered that the comet contained oxygen, organic molecules, noble gases and ’heavy’ or deuterated water different to that found on Earth.
    As scientists continue to analyse data from Rosetta’s instruments, including the ionised gas or plasma, the results are improving our understanding of comets. Mission data is also being delivered to an archive as a future resource.

    Rosetta orbits the Sun every 6.5 years and will pass the Earth again, visible from ground-based telescopes, in 2021. ESA’s future Comet Interceptor mission will build on Rosetta’s success when it performs a flyby of a comet. But, unlike Rosetta, the comet will be new to our Solar System.
