The ultraviolet (UV) portion of the electromagnetic spectrum provides some of the most powerful diagnostics to shape our understanding of stars, planets, galaxies, and all the material in-between, but it has long been one of the most difficult regions to explore. The principal go-to observatory for astronomers is the venerable Hubble Space Telescope—the most sensitive ultraviolet eyes into the universe we have ever known. NASA is now studying a behemoth space observatory as a potential successor to Hubble to answer the pressing questions of the future, the Large UltraViolet/Optical/InfraRed Observatory (LUVOIR). At a massive 50 feet in diameter, LUVOIR would be more than 40 times larger than Hubble and 150 times more sensitive, but it’s more than a decade from being built.
Recent advances in technology have opened up a new and perhaps unexpected dimension in UV space astronomy that will fill the gap between Hubble and a possible LUVOIR: small satellites. At sizes ranging from a shoebox to a mini-fridge, these tiny spacecraft have the potential to do science that is exceedingly difficult even for Hubble, and outside the capabilities of other space astronomy missions.
In this talk, Dr. Brian Fleming will tell us what has changed to make a shoebox satellite suddenly have outsized potential, and highlight some exciting science that will be carried out by LASP scientists with the first batch of astrophysics CubeSats in the coming years.
NASA’s Global-scale Observations of the Limb and Disk (GOLD) mission has observed dramatic and unexplained shifts in the location of features in the Earth’s ionosphere surrounding the equator. Unanticipated changes in the nighttime ionosphere can lead to disruptions in communication and navigation that depend on satellites, such as GPS.
GOLD is an ultraviolet imaging spectrograph that was designed and built at LASP and is hosted on the SES-14 communications satellite. The latest discoveries from the mission are challenging mission scientists and were published last week in Geophysical Research Letters.
Since reaching orbit in October 2018, GOLD has been making observations of the Equatorial Ionization Anomaly (EIA), regions of the ionosphere with enhanced electron density north and south of the magnetic equator. One of the primary goals of the mission is to better understand the behavior of the EIA and the instabilities within it. GOLD presents a new ability to image the variability of ionospheric plasma and, ultimately, to understand its causes.
For Nick Schneider, teaching isn’t just something that he has to do—it’s his passion. And one that’s being recognized by the Astronomical Society of the Pacific (ASP) with this year’s Richard H. Emmons award.
This award, which recognizes extraordinary teaching in astronomy, is the only such award given at the national level, and Schneider is the first recipient to focus on planetary science, rather than astrophysics, since the award’s inception in 2006.
A first-of-its-kind camera developed in partnership between CU Boulder and Ball Aerospace will soon be landing on the moon.
NASA announced today that it has selected a scientific instrument, called the Lunar Compact Infrared Imaging System (L-CIRiS), for its Commercial Lunar Payload Services program. The camera will ride along with one of three robotic landers that will touch down on the lunar surface in the next several years—a key step in NASA’s goal of sending people back to the moon by 2024.
LASP planetary scientist Paul Hayne, who is leading the development of the instrument, said that the goal is to collect better maps of the lunar surface to understand how it formed and its geologic history. L-CIRiS will use infrared technology to map the temperatures of the shadows and boulders that dot the lunar surface in greater detail than any images to date.
