The SRM Space Probe project aims to launch an unmanned high altitude balloon by November 28th, 2013 to photograph and study comet ISON from 30km altitude. The key aspects of the project include developing a payload consisting of a telescope, camera, and other instruments to observe and record data on ISON. A critical component is the high altitude balloon assembly, which will carry the payload capsule to the target altitude. The project team has designed the payload capsule and balloon assembly, and plans to conduct a test flight before the November launch to photograph the sungrazing comet ISON as it passes close to the sun.

1. SRM SPACE PROBE
CHASING THE INCOMING SUNGRAZER...

2. INTRODUCTION
SRM SPACE PROBE is a research project under the
department of Aerospace (SRM University,
Kattankulathur).
We are sponsored by Maple Software. Our task is to
Launch an unmanned high altitude balloon till 28th
november
2013 and accomplish all the mission objectives

3. RESEARCH SUBJECT (ISON)
Comet ISON will make an appearance in Earth's
sky in 2013. While it's hard to predict just how
bright the comet will be when it arrives, some
astronomers are saying that it could be as bright
as the full moon or perhaps, even visible in daylight.
ISON is considered a "sungrazer," meaning that it
will pass very close to the sun when it gets into
the inner solar system in November 2013.
Our mission is to take photograph of this comet from an altitude of 30 km and use it for
Estimating the composition of ISON comet.

10. PLAN OF THE PROJECT
1) Selection of students
2) Purchasing of required materials
3) Design and Build Flight System
4) Test Flight System
5) Develop Payload
6) Launch
7) Recover
8) Study of observed / Stored Data

11. DESIGN
We choose to have
capsule shaped module
to resist shear forces
and for stability factor
as drag is also low for
uniform bodies
