WIND Petal Orbit
WIND Petal Orbit
WIND Spacecraft to Begin Petal
After returning from several months at the L1 Langrangian
point--the point where the gravitational and centrifugal pull of
the Sun and Earth cancel each other--ISTP's Wind spacecraft will
soon make two passes by the Moon. Having spent the past few months
cross-calibrating its instruments with those from the ACE
spacecraft, Wind will now begin a six-month series of “petal”
orbits that will take it out of the ecliptic plane.
Starting in October 1998, Wind will fly in an orbit that brings it
as close as 10 Earth radii (about 63,000 km) and as far as 80 Earth
radii from our planet. More importantly, the orbit will take Wind
at an angle of 60 degrees from the ecliptic plane--the plane of
Earth and most of the planets. Wind's trips above and below the
ecliptic will allow the spacecraft to sample regions of
interplanetary space and of the magnetosphere that have never
before been studied.
ISTP Conducts Successful Workshop
- Latest ISTP workshop -- held April 7-9 at GSFC -- attracted 187
participants from at least 15 countries.
- Included interactive panels on the highlights of ISTP and the
future of the mission. Science team suggested that time has come
for an ISTP monograph.
- Workshop included a preview of some of the 200+ ISTP-related
papers to be presented next month at AGU.
- Highlights included evidence for reconnection in Earth’s
magnetic tail and plans for Wind’s exploration of high-latitude
- Outreach session showcased a dozen efforts being made to share
space physics with students and the public.
|New Poster Conveys Excitement,
Relevance of the Sun-Earth Connection
ISTP has created a new 22" by 34" poster for high school students
and adult science buffs. The poster highlights the dynamic,
electric connection between Sun and Earth by using more than two
dozen images (front & back), a magazine-length article on space
weather, and a CME tracking exercise. 28,000 copies of "Storms
from the Sun" are now being produced for distribution at the April
meeting of the National Science Teachers Association and other meetings.
It will also be available through NASA Educator Resource Centers.
A Spanish-language version of the poster will be produced later
