Observing Notes From Hubble and Non-Visible
Wavelengths
- Hubble Space Telescope
- On 26 and 27 August the team of James Bell (Cornell University) and
Michael Wolff (Space Science Institute) imaged Mars using the
Wide Field and Planetary Camera 2 instrument on HST.
These images have the best resolution ever seen from Earth and show
great details. Quite distinct are the caldera of the Tharsis volcanoes,
especially that of Olympus Mons. The North Polar Hood is quite visible
on the northern limb; this appears to be the only prominant condensate
cloud activity. There is also some dust activity over the South Polar Cap.
Results of their image analysis will appear in the peer-reviewed journals.
- Ultraviolet Observations
- For several weeks in August and September
Michael Snowden observed Mars
from the CASLEO
0.6-m Hogg telescope in Argentina. He collected images in the Johnson
bands of U, B, V, R, and I. The images presented here are some of
his U-band images with some I-band images to give some sense of
geography. The surface of Mars is almost non-reflective in U and
shows little to no variation which dramatically increases the contrast
between it and ices in clouds and on the surface.
- Near-Infrared Observations
- The team of David Klassen
(Rowan University), David Glenar (NASA Goddard Space Flight Center),
Diana Blaney (NASA Jet Propulsion Laboratory), Gordon Bjoraker
(NASA Goddard Space Flight Center), and James Bell (Cornell University)
have been working on a program of
observations using the
NASA Infrared Telescope Facility
at Mauna Kea, Hawaii. The program uses two faciltiy instruments
(NSFCAM and
SpeX)
to perform imaging spectroscopy at 1.5–4.1 µm. They had a
series of 2–3 night runs, one each month from July through November.
Their project includes measuring the water abundances
in ice clouds and trying to characterize the spectral signature of
the Martian surface and airborne dust. In the images, some interesting
features are readily apparent: from 1.925–2.250 µm the
volcano peaks of Olympus and Elysium can be seen as bright spots (at
these wavelengths, the CO2 atmosphere is a strong absorber
and since there is less atmosphere over the moutains, there is less
absorption); the south polar cap disappers in the 3–4 µm
wavelength region due to the apsorption of CO2 ices;
there do not appear to be many extensive cloud formations at least
in the basic images—more work is being done to assess the
amount of cloud cover, so stay tuned!
- Sub-Millimeter Observations
- Observers R. Todd Clancy (Space Science Institute), Brand Sandor (Space
Science Institute) and Gerald Moriarty-Schieven (James Clerk Maxwell
Telescope) have made observations using the James Clerk Maxwell Telescope
(JCMT) atop the summit of Mauna Kea, Hawaii.
They observerd at several submillimeter spectral lines on Aug 28 and Sep 4,5.
These observations include disk center measurements at 362 GHz for
H2O2
and mapping measurements of 12CO and
13CO to help study atmospheric winds.
Mapping is done at 5 points: north, south, east, and west limbs, and disk
center. Preliminary analysis of these data were presented at the
2003 Division for Planetary Sciences conference and show good zonal wind
measurements over the 20–70 km altitude range. Forthcoming
results will be published in the peer-reviewed journals.
- Radio Observations
- 22 GHz mapping of water vapor limb emission from the Very Large Array
(VLA) near Socorro, New Mexico are being made, and are being analyzed,
by the team of R. Todd Clancy (Space Science Institute), Mark Gurwell
(Harvard/Smithsonian Astrophysical Observatory), and Bryan Butler
(National Radio Astronomy Observatory/VLA). These data will help
them measure the water vapor abundances in the Mars atmosphere as a function
of altitude.
