Complex organosulfur molecules on comet 67P: Evidence from Rosetta orbiter and the lab
Updated: 2023-06-30 14:20:01
The Rosetta orbiter spectrometer for ion and neutral analysis (ROSINA) instrument orbited comet 67P to revolutionize our understanding of cometary material composition. A key finding of the satellite was to explore the composition of comet 67P/Churyumov-Gerasimenko. In a new report published in Science Advances, Ahmed Mahjoub and a team of planetary scientists in the Jet Propulsion Lab at CalTech, the Space Science Institute Colorado, and the University of Bern in Switzerland, used the ROSINA data to study dust particles volatilized during a dust event in September 2016.

But Why Study Them NASA recently used its powerful High Resolution Imaging Experiment HiRISE camera onboard the Mars Reconnaissance Orbiter to take a breathtaking image of a dust devil traversing Syria Planum on Mars . One unique aspect of dust devils is their shadows can be used to estimate their height , which have been estimated to reach 20 km 12 miles into the Martian sky . Studying dust devils on Mars is a regular

Using the 4.3-m Lowell Discovery Telescope (LDT), astronomers Kathryn F. Neugent and Philip Massey, have observed the nearby Andromeda galaxy. In result, they detected 19 new Wolf-Rayet stars in this galaxy. The finding was reported in a paper published June 22 on the pre-print server arXiv.
Although technically challenging, space experiments are a scientifically important aspect of astrobiology and astrochemistry investigations. The international space station (ISS) offers an excellent example of a long-term research platform orbiting the Earth, with highly successful advances to implement experiments in space, which has contributed to a wealth of scientific data in the past few decades. Future space platforms present additional opportunities for experiments in astrobiology and astrochemistry.
