Who Are We?

SPACETIME ARCHIVES is run by a team of prior NASA and SSP interns and  Texas Astronomical Society members. We specialize in astrophysical research, but also dabble in aerospace engineering, earth sciences, quantum mechanics, and other scientific fields. We love to learn, but we love to teach even more.

About Rishika Porandla

Now a rising sophomore at Princeton University studying Astrophysics with intended minors in Statistics & Machine Learning and Engineering Physics, Rishika is an aspiring experimentalist and loves the intersection of heliophysics, laboratory astrophysics, and space plasma instrumentation. This summer, Rishika is engaged in dual research positions. At the Princeton Space Physics Laboratory, she is leading NASA-funded investigations comparing graphene and amorphous carbon foils for use in Electrostatic Analyzers (ESAs), aiming to optimize angular scattering and beam transmission properties in heliospheric particle detection. In parallel, at the Princeton Plasma Physics Laboratory, she is contributing to the redesign of a hemispherical Electron Energy Analyzer for the FLARE experiment, refining energy resolution and detector integration for reconnection-driven plasma diagnostics. Her research has also tackled environmental data science and planetary mission leadership analysis for NASA Headquarters and USAID.

Rishika is a recipient of the USAID Science Champion Award, a CERN BL4S Global Finalist, and an Honorable Mention awardee for the AAS Chambliss Astronomy Achievement Award.  Looking ahead, Rishika aspires to pursue a Ph.D. in Astrophysics and lead instrumentation development for heliophysics and astrophysical plasma missions. She hopes to combine laboratory precision with space-based exploration to better understand the energetic particles, turbulent fields, and dynamic processes that shape our solar system and beyond.

About Spacetime Archives

Organization overview

Spacetime Archives (STA) is an informal education nonprofit organization located in Dallas, Texas dedicated to unique space science education involving free, public-access STEM outreach to underserved demographics (women, racial/ethnic minority groups, low-income youth, and students with disabilities). In 2023, STA reached over 50,000 students nationally through career seminars, research mentorship, NASA ASTRO CAMP®, and our educational magazine distribution. STA additionally supports 10+ global partnerships that has enabled STA programs to reach over 6,000 international students. STA continues to collaborate with NASA through various programs, such as ASTRO CAMP Community Partners as a Texas Astronomical Society partner. STA additionally engages with NASA personnel, including Goddard Space Center Science Writers, for free educational seminars and utilizes NASA telescope and radio imaging data for the Spacetime Archives Student Research Fellowship Program.  

Strategic Goals

Strategic Goal 1.0: Target research and learning opportunities to underserved youth and public schools in regional and international low-income districts.

Objectives: 

  • 1.1 Provide access to the Spacetime Archives comprehensive Astrophysics curriculum to engage youth in NASA mission science.
  • 1.2 Stimulate engagement in lunar exploration and space research through the Spacetime Archives Student Research Fellowship (SASRF).
  • 1.3 Prioritize the exposure of students in low-income districts, students with learning, physical, or cognitive disabilities, and girls to STEM opportunities.


Strategic Goal 2.0: Enable free, online access to career resources, eliminating exclusivity barriers to professional development for students.

Objectives: 

  • 2.1: Diffuse access to career seminars with NASA-employed individuals and interns to public youth, encouraging counseling, tutoring, and further interactions.
  • 2.2: Design intellectually-stimulating workforce opportunities for students, including SASRF, internship acquisition seminars, and content creation for STA, to foster interest in the physical sciences.

Current work

Currently Spacetime Archives boasts an impressive portfolio including seminars with recorded interviews and transcripts that have reached 5,000 students nationwide with NASA Deputy Associate Administrator Casey Swails, NASA Science Writer Mara Johnson-Groh, and an upcoming event with Courtney Black, the International Space Station U.S. Laboratory Education Project Manager. 


Beyond seminars, STA provides career resource guides for Aerospace Engineering, Astrophysics, Medicine, etc., weekly updating news and scientifically minded blog posts garnering about 1,500 views each, presentations, YouTube tutorials, college counseling, tutoring, study materials, and a highly successful research mentorship program: Spacetime Archives Student Research Fellowship (SASRF). Other key projects include STA’s comprehensive, free Astrophysics curriculum for middle and high school students and its 87-page educational magazine (Summer 2023 edition).


SASRF dismisses the traditional exclusivity of most high school research programs, consistently accepting the majority of applicants and connecting them to scientific research databases and resources. Accepted students are paired with an experienced mentor, either individually or within a research group of shared interests. The researchers then identify a research topic or question of interest, and their mentor will facilitate and assign their preliminary assignments, data collection, and data analysis.


STA additionally partners with Texas Astronomical Society to execute the NASA ASTRO CAMP® program throughout the Dallas-Fort Worth Metroplex. The STA ASTRO CAMP targets disadvantaged groups to reinforce basic biology, chemistry, and physics skills in students, while also introducing youth to engineering principles and mathematics that they will employ in their future classwork and careers. With our program material coming straight from NASA-designed initiatives, we provide authentic opportunities for citizens to immerse themselves in engaging, stimulating STEM activities, thus preparing them for potential NASA employment.
