Announcements of Opportunity
Special Note for SURF@JPL 2024
JPL is operating under a continuing resolution (meaning they are waiting for approval from Congress of NASA's 2024 budget). Additionally, due to other factors, JPL is concerned about a potential budget decrease. This will impact the number of summer internships available. We are working closely with JPL leadership to minimize the impact, but you can expect that AOs will likely not get posted until later this term. To accommodate this later timeline we will offer a second SURF@JPL application deadline. (This extension is for SURF@JPL only.)
- Students who find a JPL mentor early are encouraged to apply by the regular February 22 deadline. For applicants who meet this deadline, awards will be announced on April 1.
- Students who find a JPL mentor later will need to apply by April 19. Awards for this round of applications will be announced on May 6.
Students are also encouraged to apply to the JPL SIP program, which has an application deadline of March 29. For more information about SIP, visit: https://www.jpl.nasa.gov/edu/intern/apply/summer-internship-program
SURF@JPL: Announcements of Opportunity
Announcements of Opportunity are posted by JPL technical staff for the SURF@JPL program. Each AO indicates whether or not it is open to non-Caltech students. If an AO is NOT open to non-Caltech students, please DO NOT contact the mentor.
Announcements of Opportunity are posted as they are received. Please check back regularly for new AO submissions!
**Students applying for JPL projects should complete a SURF@JPL application instead of a "regular" SURF application.
**Students pursuing opportunities at JPL must be U.S. citizens or U.S. permanent residents.

Excalibur: Exoplanet data reduction pipeline for ARIEL/CASE. Data reduction methodoly impact on the transit spectrum using JWST NIRISS and NIRspec datasets.

Background: | Excalibur is the data reduction pipeline for the ESA/NASA M4 ARIEL/CASE, designed to ingest survey type mission datasets and provide reduced products to the Exoplanet community. With ARIEL/CASE launch date approaching, Excalibur escalates its efforts to not only answer the needs of large datasets (about a thousand targets) in terms of data reduction facility, but to also provide alternative software solutions and performance assessment across key intermediate products. The core structure was stressed tested with HST data and now opens its gate to JWST data, where wavelength coverage is similar to ARIEL/CASE. | ||||||||
Description: |
The successful candidate is expected to - familiarize with light curve parameter retrieval and produce the exoplanet spectrum of selected JWST targets using Excalibur data reduction codes - perform code comparison outputs with alternative system parameters, in particular stellar characteristics leading to limb darkening coefficients. - [OPT] assess the influence of the choice of stellar parameters for all selected targets onto the reduced exoplanet spectrum |
