LPUSAT - A Satellite to Study Universe


Our mission is to bring together students from various disciplines and practitioners from
the University for enhancing systems approach and encourage space technology among
students by giving room for interdisciplinary research, sharing the knowledge of engineering
skills and collectively work to design, launch and operate Nano-satellite systems and
encourage system engineering among the them. Our team has reiterated its commitment in
encouraging and putting in place frameworks geared towards encouraging our university students
and young minds in the space sector to exhibit their skills in the multidisciplinary research.Our final
goal is to successfully launch and operate Nano satellite with minimal or no complications and have
it performed as per our expectations and commands which in turn helps us in building the nation.

The mission objective of LPUSAT are as follows:
 To design, develop, and launch a payload to study the structure, origin, and
evolution of the Universe by Diffuse X Ray Background.
 Using the payload data for scientific study on the Universe and its chemical
composition, Study about the atmosphere with X Rays.
 To gain expertise in design, development, testing, maintain a satellite on orbit
 To gain experience in design, fabricate, test, and operate satellite
 To gain experience in design various detectors and sensors
 To gain experience in system engineering and team work

Payload : X Ray Astronomy

X-ray astronomy detectors are instruments that detect X-rays for use in the study of
astronomy. X-ray astronomy looks at high energy, short wavelength light, over 40 times smaller
than the shortest wavelength our eyes can detect. This light, emitted by gas heated to millions
of degrees, provides a glimpse into extreme environments like black holes, neutron stars, and
colliding galaxies.
Million-degree gas can be found throughout the universe. In x-ray binary systems, a neutron
star or black hole – the very dense remnant of a deceased massive star – is orbiting another star
and stealing gas from its companion. The stolen gas gets caught up in a disk that spirals around
the stellar remnant. The intense gravity of a neutron star or black hole accelerates the
spiralling gas to high speeds, heating the material in the disk to extreme temperatures, and
causing it to glow in x-ray light.
Any time interstellar gas is rapidly compressed, it can be heated enough to emit x-rays. The
shock front from a supernova can send a wave of x-ray emission rippling through space. X-rays
also permeate galactic clusters – the largest structures in the universe. In a galactic cluster,
thousands of galaxies dance around one another, drawn together by their mutual gravitational
attraction. Collisions between member galaxies are common. The energy released in these
titanic clashes is enough to heat the tenuous gas that permeates the cluster.
A principal question with selecting a detector for a given application is to determine what our
science goals are. One detector might be better at making an image of a source, recording
detailed position information of the incoming light. Another detector might be better at
measuring the spectrum of a source, which requires getting a very accurate measurement of
the energy of each incoming X-ray. Still another detector might be better at recording timing
information, measuring the exact time of arrival for each of the incoming X-ray photons. Ideally,
a detector would be able to do all three of these: positional information, energy resolution, and
timing information. In practice, detectors are optimized for one and are less capable of the
others.
X-ray detectors, then, must be made of materials that X-rays will interact with. Those materials
might be a gas that high energy photons will cause to "glow" or solid materials that will stop a
high energy photon in its tracks. The detector size and materials must be designed so X-rays
that enter are completely absorbed, producing some sort of signal in the process that you can
measure.
