Because this message is distributed through several mailing lists, we
apologize if you receive more than one copy of this announcement.
Please forward this information to colleagues that may not have
obtained this email.

Hope to hear from you soon.

Ionospheric Sounding with GPS

There is an old adage in science and engineering: One person’s signal
is another person’s noise. Most Global Positioning System (GPS)
users consider the delay or advance of signals by the ionosphere to
be noise, as their presence reduces positioning accuracy. On the
other hand, one can take advantage of these errors to characterize
the ionosphere. The session will review (1) the latest modeling
techniques, methods, applications and results for ionospheric total
electron content (TEC) modeling using ground-based GPS networks
including e.g., the International GPS Service (IGS), Continuously
Operating Reference Stations (CORS) and the Wide Area Augmentation
System’s Reference Stations; (2) the current spaceborne missions such
as CHAMP, SAC-C, IOX, GPS/MET, GRACE, etc., which observe electron
density profiles using occultation techniques; (3) future GPS
occultation satellite missions such as COSMIC, ICESAT, FEDSAT and
e-POP. We particularly welcome contributions related to NASA’s Living
with a Star research program. The growing networks of ground-based
continuously operating GPS receivers and new constellations of GPS
occultation satellites represent a major new data source for space
weather analysis and prediction. We encourage contributions related
to the impact of these new techniques in the areas of space weather
analysis and prediction.

5. Job Announcement – Research Scientist-National Virtual Observatory at
the Universities Space Research Association (USRA)
From: Ginny Peles

The Universities Space Research Association (USRA), in conjunction with the
NASA/Goddard Space Flight Center’s Laboratory for High Energy Astrophysics
(LHEA), is seeking a research scientist to work on-site at GSFC, with
NASA’s developing National Virtual Observatory (NVO) project.

The successful candidate will be responsible for the development of
interfaces to astronomical archives at the HEASARC in coordination with the
NVO collaboration. This position requires the application of new
information technologies, especially in the data grid area, to science
research activities in high-energy astronomy.

The successful candidate should possess a Ph.D., or at minimum, a Master’s
degree, in astrophysics or information sciences. Experience in using
science data archives for research, and familiarity with emerging
technologies including the data grid, web services, and metadata standards
is highly desired. Good communications skills and the ability to work in a
distributed collaborative environment are essential.

USRA is a non-profit university consortium, chartered to broaden
opportunities for collaboration between university and government space
research communities. EOE. Applications received by 17 January 2003 will
receive full consideration. Apply on-line at: and/or mail letter describing
research interests, complete CV and publication list, and contacts (include
e-mail addresses) for at least three references to:

From: Ginny Peles

Summer Student Research Opportunities (SSRO)

Sponsored by Universities Space Research Association (USRA) and the
NASA Goddard Space Flight Center’s (GSFC) Space Sciences Directorate
Greenbelt, Maryland

June 9 – August 15, 2003

The Program

A limited number of paid positions are available to undergraduate and
graduate students to encourage an interest in physics, solar physics,
extraterrestrial physics, astronomy, astrophysics, and computer science/
information technology. Selected students will be teamed with a scientist
mentor having parallel scientific interests, to jointly develop and carry
out a research-related project at GSFC over the 10-week period.

In addition to the primary research project, participants will be expected
to attend scientific colloquia, participate in lunchtime brown bag
seminars, and visit other GSFC laboratories. Participants will receive a
tour of the Goddard campus conducted by a representative of the GSFC Public
Affairs Office. At the conclusion of the 10-week period, participants will
present oral and written reports on their projects to their fellow summer
students, their mentors, and other members of the Space Sciences
Directorate. On a case-by-case basis, participants may be granted
incentives to continue collaborative projects during the next academic year.


The Space Science Directorate is comprised of the Laboratories for High
Energy Astrophysics, Astronomy and Solar Physics, Extraterrestrial Physics
as well as the Space Science Data Operations Office. Scientific research
within the laboratories is directed toward both experimental and
theoretical activities in the following areas: x-ray, gamma-ray, and
cosmic-ray astrophysics; UV/optical astronomy; solar physics; infrared
astrophysics; astrochemistry; interplanetary physics; planetary systems;
planetary magnetospheres; and, electrodynamics.

A sampling of past and possible future projects includes the following:

* Cosmic rays: investigating the processes of cosmic ray propagation and
acceleration, characterizing the cosmic ray composition and sources.

* Detectors: development of high-energy resolution calorimeters for x-ray
spectroscopy (Constellation-X), and scalable, large area micro-well arrays
for all sky monitoring (ISS-Lobster).

* Galactic binaries: the study of the spectral variation of x-ray bursts.

* Gamma-ray bursts: using Bayesian analysis algorithms to characterize
pulse distributions in gamma-ray burst (GRB) temporal profiles.

* Ionospheric response: investigation of global ionization, heating, and
flow of ionospheric plasma in response to solar and magnetospheric energy
inputs, using POLAR/TIDE, FAST, and DMSP spacecraft.

* Interplanetary gas and dust: exploration using a combination of direct
and indirect observations of interstellar atoms and neutralized solar wind
ions from the IMAGE/LENA imager, and energetic “pickup” ions in the solar
wind from Wind, ACE, and Ulysses.

* Interstellar matter and molecular clouds: studying the diffuse gamma-ray
emission observed by the Energetic Gamma Ray Experiment Telescope (EGRET)
to evaluate the coupling of cosmic rays to interstellar gas in the outer

* Magnetospheric response: the coupling of energy and plasma from the
solar wind into magnetospheres, creating space weather, is studied using
observations from WIND, POLAR, FAST, and IMAGE missions, in comparison with
relevant theories and global simulations.

* Particle analyzers and imagers: development of innovative particle and
plasma velocity analysis and detection systems, including imaging systems
for electrons, ions, and neutral atoms.

* Solar wind acceleration and dynamics: observations from several
spacecraft are compared with theories of the solar wind to investigate the
processes that heat the corona, accelerate the wind, and influence its

* Stars: continuous monitoring of the x-ray variations from the extremely
massive star Eta Carinae using the Rossi X-ray Timing Explorer (RXTE).

* Supernovae and supernova remnants: analyzing the x-ray emission from SNR
G21.5-0.98 to better understand the x-ray emission from composite type
supernova remnants.

* Black holes: mapping the accretion history of super-massive black holes.

* Mechanical design and analysis: modifications and additions to existing
project instruments.

* Space data systems: development of autonomous flight and ground systems
for command and data handling and flow.

Compensation and Support

Selected students will be placed on USRA’s payroll as Student Assistants
and compensated at the rate of $10 per hour for undergraduates and $12 per
hour for graduate students for 40 hours per week for 10 weeks. USRA will
reimburse reasonable roundtrip domestic travel expenses for non-local
participants. A variety of local housing arrangements are available and
will be funded for program participants only (no family members).

Eligibility and Selection Criteria

The program is open to students enrolled in, or accepted to, accredited U.
S. undergraduate and graduate programs in physics, astronomy, astrophysics,
engineering, computer science, or related disciplines. Students will be
selected based on the following:
* academic record (official transcripts required)
* motivation and career interests
* preparation to contribute toward research in astronomy, astrophysics,
solar/magnetospheric physics, and space data and information sciences
* relevance of career goals and experiences to USRA and GSFC scientists
