TL;DR: The MAVEN spacecraft has eight science instruments (with nine sensors) that measure the energy and particle input from the Sun into the Mars upper atmosphere, the response of the upper atmosphere to that input, and the resulting escape of gas to space as mentioned in this paper.

TL;DR: The Wide Field Planetary Camera 2 (WFPC2) was installed in the Hubble Space Telescope (HST) in 1993 December and has been providing high-quality images as mentioned in this paper.
Journal ArticleDOI
Hubble Space Telescope Observations of the Disk and Jet of HH 30
Christopher J. Burrows,Christopher J. Burrows,Karl R. Stapelfeldt,Alan M. Watson,John Krist,Gilda E. Ballester,John Clarke,David Crisp,John S. Gallagher,Richard E. Griffiths,J. Jeff Hester,John G. Hoessel,Jon A. Holtzman,Jeremy Mould,Paul A. Scowen,John T. Trauger,James A. Westphal +16 more
TL;DR: In this paper, the authors show that a flared disk with a radius of about 250 AU obscures the star H 30 in Taurus has been imaged with the Hubble Space Telescope WFPC2.
Journal ArticleDOI
Flicker (1f) noise: Equilibrium temperature and resistance fluctuations
TL;DR: In this article, the authors measured the voltage noise in continuous metal films and showed that the noise arises from equilibrium temperature fluctuations modulating the resistance to give a power spectrum proportional to the mean voltage across the sample.
Journal ArticleDOI
Detection of H 3 + on Jupiter

TL;DR: In this paper, the authors presented high-resolution spectra at a wavelength of 2 μm, recorded at the Canada-France-Hawaii Telescope (CFHT), which they believe to be the first astronomical spectroscopic detection of H3+.
