The student will receive hands-on experience in space environment testing with this opportunity to plan and execute thermal vacuum tests for the Magnetospheric Multi-Scale (MMS), a 4-spacecraft mission that will explore magnetic reconnection through studying the Earth's magnetosphere. Magnetic reconnection is a little-understood process by which magnetic energy is released in the form of heat and charged particle kinetic energy when magnetic fields cross and reconnect. Through studying this process in space, scientists will gain a better understanding of solar flares, coronal mass ejections, and other phenomena that affect Earth-orbiting spacecrafts and power grids on Earth.
Thermal vacuum testing is critical to ensuring a successful mission. The student will learn about how deep space flight hardware is qualified under simulated space conditions in thermal vacuum chambers. They will understand the facility capabilities, including the use of the chamber shrouds, gaseous and liquid nitrogen, heater circuits, cryopanels, temperature sensors, and thermoelectric quartz crystal microbalances (TQCMs) to create and monitor the environment to which the hardware is exposed. They will apply this knowledge to develop the thermal vacuum tests for MMS, which will require gathering the test requirements and formulating detailed test procedures used for carrying out the tests in the lab.
The student will take ownership of creating tests that will (1) cycle flight hardware at the hot and cold temperature extremes that the MMS spacecraft will experience in orbit, and (2) bake-out the hardware to achieve cleanliness requirements.

The Space Technology 5 mission consisted of 3 spinning spacecraft in a formation measuring changes in the Earth's magnetic field over short time intervals. With assistance of their mentor, students will put together a spacecraft dynamics simulator which will model spacecraft attitude (orientation), rate, orbit, magnetic field, and sensors. The results will then be compared to actual performance of the spacecraft.

StarCamp is a 10-week summer engineering apprenticeship program at Goddard Space Flight Center for students of all levels to come together as teams to address projects of interest to NASA. Student teams will be coached by an experienced project manager and mentored by NASA experts from all areas applicable to the project at hand. Project concepts are initially discussed and students are guided to create requirements and develop a plan for implementation with milestones and deliverables. Weekly meetings address the progress of the project and correct the development path as appropriate to meet the project goals. The main objective is to provide students with an opportunity to work as a team in a professional environment while creating engineering solutions that will be used by NASA.
The StarCamp engages a team of high school students in documenting the projects with photographs and video recording, and preparing slide presentations and posters to showcase the projects. The StarCamp also requires website development and content management as well as online social networking coordination. Students applying for this position shall be familiar with the technologies used for media production, website creation, and online social networking, as well as project presentation tools such as PowerPoint.

We are currently developing several laser communication testbeds to support the Laser Communications Relay Demonstration (LCRD program). The objective of the LCRD program is to demonstrate the feasibility of high data rate communication using laser beam from the geosynchronous orbit to Earth. One of the testbeds we are pursuing is to demonstrate laser power scaling using fiber laser amplifiers for space applications. During this testbed development we will require autonomous testing of the these amplifiers with computer controlled test setup. The objective of this project is to develop a computer program that will be used for testing the performance of these amplifiers.

Correlations between space weather effects (geomagnetic storms, plasma injections on the nightside of Earth, etc) and the north-south component of the interplanetary magnetic field (IMF) have been well studied. Correlations with other orientations of the IMF have not been examined as well. Our group uses a combination of simulations and observations to understand how orientation of the IMF other than north-south might affect the inner magnetosphere of Earth. An intern might be asked to: (1) identify and analyze satellite data during a period of non-north-south oriented IMF; (2) simulate the inner magnetosphere environment when the IMF is in different orientations using our models and programs; and, (3) write a summary of the results of their research. We are looking for students who are curious, hard-working, and have a desire to learn both research skills and programming. We will teach all the skills necessary to complete this project, though previous knowledge is good. Any student interested in space physics and space weather is encouraged to apply.

Tidal heating is a universal phenomenon in space,
and is the cause of the extremely high rate of volcanism on Jupiter’s
moon Io. Meanwhile, the number of known extrasolar planets is rapidly
increasing, and the size of planets discovered now spans from gas
giants larger than Jupiter down to rocky bodies as small as the Earth.
The tidal heating of Io is caused by a particular orbital arrangement
in the moon system of Jupiter, and it is possible that known
exoplanets, or exoplanet candidates, may experience similar conditions
as Io, and thus may experience extreme tidal heating. This project
would seek to search among recently discovered exoplanets and
exoplanet candidates for cases where tidal heating may be strong, and
if so, to explore what level of heating and subsequent volcanism may
result on those worlds.

Laser altimeters measure the distance from the spacecraft to the planet surface and provide a surface topography map by subtracting the spacecraft to surface distance from the spacecraft orbit height above a reference point. NASA Goddard Space Flight Center has built several laser altimeters that have successfully mapped Mars, Moon, Earth, and Mercury. Laser altimeters not only provide distance measurements but also surface reflectance measurement to the laser light. We have also found that the noise monitor outputs from these laser altimeters can be used to infer the scene brightness under solar illumination, like a single pixel camera. The map is unique because of its narrow spectral range and precise geo-location from the laser altimetry measurements. We have successfully mapped Mars surface reflectance using the noise monitoring data from the Mars Orbiter Laser Altimeter. We are hoping the summer interns can help us to process the recent noise monitoring data from the Lunar Orbiter Laser Altimeter and the Mercury Laser Altimeter, which are still in orbits today, to construct a similar map for the Moon and Mercury.
