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.

New NASA Operation IceBridge data shows that summer lakes, that form on the surface of the Greenland Ice Sheet become buried and water persists throughout the winter. Little is known about why some lake on the ice sheet drain and others do not. Much is to be discovered by studying the life cycle of these lakes.
For this project a student will monitor the evolution of select lakes that form on the surface of the Greenland Ice Sheet during the summer. They will track, using visible satellite imagery, when lakes form, drain or freeze over and if the lakes life cycle changes from one year to the next.

In this internship, students will participate in the field testing of a new instrument for measuring methane and carbon dioxide in the atmosphere. This will include both indoor and outdoor work. Duties include monitoring equipment, collecting and analyzing data, and recording project work in a lab notebook with neat handwriting. Position requirements follow:
Position 1 requirements:
- Completion of two or more high school level science courses (such as Chemistry, Physics, Earth Science, Biology).
- Completion of two or more high school level math courses (such as Algebra 1, Algebra 2, Geometry, Trigonometry, Calculus).
- Good communication skills (The intern should be able to learn technical material, speak clearly, and write in complete sentences).
- Programming experience in Labview
Position 2 requirements:
- Completion of two or more high school level science courses (such as Chemistry, Physics, Earth Science, Biology).
- Completion of two or more high school level math courses (such as Algebra 1, Algebra 2, Geometry, Trigonometry, Calculus).

The NASA Earth Observing System Data and Information System (EOSDIS) collects and processes remote sensing data from earth observing satellites, aircraft and ground based measurements, and distributes data products to science users around the world. EOSDIS performs these data functions at 12 data centers across the country led by a project office at the Goddard Space Flight Center. The project office promotes EOSDIS information and capabilities via a web site currently being upgraded with interactive graphics to engage and improve the viewer’s experience. This web site describes the types of Earth science data collected and presents the facilities that store and manage the data. Describing the sources of the Earth science data is important to establishing the context for the data managed in the data system. The intern will assist the project in gathering, assessing and implementing the science missions, instruments, and measurement parameters to display on the web site in newly designed formats.
The intern will research internal and related external web sites and documentation to gather the Earth science information, conduct a review process with project staff, and update the EOSDIS web site with the approved information. A major goal is to ensure up to date information consistent with NASA Earth science program documentation, NASA HQ web sites, and EOSDIS internal consistency. The intern will also be expected to provide feedback on the graphical representations and suggest changes or improvements that, if adopted, will be implemented by the development team. During this activity the intern will learn about the Earth science program at NASA from the data system perspective. The intern will work with computer systems, security processes, and networks necessary for the data system operation.

Project Description
Seeking up to two high school students to join a team of 3-4 college to graduate students to work on formulating a feasible
mission concept and create a baseline design for an Active Debris
Removal (ADR) Mission.
Orbital debris, or space junk, is a threat to satellites, astronauts,
space station, and other space assets. Through ground tracking,
trajectory planning, and debris avoidance maneuver, spacecraft can avoid
conjunction. However, maneuvering is impractical and sometimes
impossible for spacecraft in more densely populated orbits. The
objective of an ADR Mission is to design a spacecraft that will actively
remove space debris by rendezvous & capture and deorbit. The
deorbit phase can be achieved by several methods such as: drag
enhancement devices, electrodynamics tethers, propulsive tugs, Ion Beam
Shepherding, space collector... or others.
The project will work similar to an undergraduate senior design project, where
sub-teams would form and students would take ownership of aspects of the
mission per their background and preferences. Students will be given
top-level mission objectives and requirement, and are expected to seek
creative solution of their own. The group will have a lead mentor and a
team of co-mentors from MESA, whom they can consult and seek guidance.
This is NASA Goddard Engineering organization, Applied Engineering &
Technology Directorate, or AETD's first of many future Summer Intern
Projects. This year's pilot will be hosted by Mission Engineering &
Systems Analysis (MESA) Division, home of Guidance, Navigation, and
Control Branch, Attitude Control Branch, Navigation and Mission Design
Branch, Propulsion Branch, Components Hardware Branch, and System
Engineering Branch.
In order to create a balanced team students **must** indicate their
preference(s)/interest(s) between Guidance, Navigation, and Control
(GN&C), Attitude Control, Flight Dynamics & Mission Design,
Space Propulsion, Robotics, and/or Hardware in their student statement.

This project uses space-craft-derived topogrpahic, crustal thickness and other data to search for previously unknown large impact basins on the Moon and Mars and develop a relative age sequence for them. Large impacts were very important in the development of the crusts of the terrestrial planets, and in either aiding or limiting the start of early life on the Earth (and maybe Mars). The goal is to understand the early bombardment history of these smaller bodies and to use that as a basis to understand the earliest evolution of the Earth.

Selected candidates will work in small teams in a dynamic environment that will cover all aspects of manufacturing support for a micro project. Disciplines that will be introduced will include but not be limited to compute aided design (CAD), computer aided machining (CAM), laser marking, rapid prototype production (RP) in 3 D printers, hands on machining operations, and the integration of hardware produced by their team or others into a higher level assembly. Additional duties may include operation of video cameras, editing of content into presentations for demonstrations, and development of power point presentations.
