LASP began in 1948, initially operating at CU Boulder as the Upper Air Laboratory. Since those early days launching payloads on V-2 rockets in the deserts of White Sands, New Mexico, LASP has grown to become the world’s only research institute to have sent instruments to every planet in the solar system, and to Pluto.
Come celebrate 70 years of exploring the Earth, our solar system, and beyond.
We’ll have tours of all our facilities and LASP Director Daniel Baker will present a colloquium on the history of LASP at 4 p.m. in the SPSC building.
On its last orbits in 2017, the long-running Cassini spacecraft dove between Saturn’s rings and its upper atmosphere and bathed in a downpour of dust that astronomers call “ring rain.”
In research published today in Science, LASP research associate Hsiang-Wen (Sean) Hsu and his colleagues report that they successfully collected microscopic material streaming from the planet’s rings.
The findings, which were made with Cassini’s Cosmic Dust Analyzer and Radio and Plasma Wave Science instruments, come a little more than a year after the spacecraft burned up in Saturn’s atmosphere. They stem from the mission’s “grand finale,” in which Cassini completed a series of risky maneuvers to zip under the planet’s rings at speeds of 75,000 miles per hour.
Today, NASA’s MAVEN spacecraft celebrates four years in orbit studying the upper atmosphere of the Red Planet and how it interacts with the Sun and the solar wind. To mark the occasion, the team has released a selfie image of the spacecraft at Mars.
MAVEN’s selfie was made by looking at ultraviolet wavelengths of sunlight reflected off of components of the spacecraft. The image was obtained with the Imaging Ultraviolet Spectrograph (IUVS) instrument, built at LASP, that normally looks at ultraviolet emissions from the Martian upper atmosphere. The IUVS instrument is mounted on a platform at the end of a 1.2-m boom (its own “selfie stick”), and by rotating around the boom can look back at the spacecraft. The selfie was made from 21 different images, obtained with the IUVS in different orientations, that have been stitched together.
NASA’s Global-scale Observations of the Limb and Disk, or GOLD, instrument powered on and opened its cover to scan the Earth for the first time, resulting in a “first light” image of the Western Hemisphere in the ultraviolet. GOLD will provide unprecedented global-scale imaging of the temperature and composition at the dynamic boundary between Earth’s atmosphere and space.
The instrument was launched from Kourou, French Guiana, on Jan. 25, 2018, onboard the SES-14 satellite and reached geostationary orbit in June 2018. After checkout of the satellite and communications payload, GOLD commissioning—the period during which the instrument performance is assessed—began on Sept. 4.
Team scientists conducted one day of observations on Sept. 11, during instrument checkout, enabling them to produce GOLD’s “first light” image. Commissioning will run through early October, as the team continues to prepare the instrument for its planned two-year science mission.
