APL’s Near Earth Asteroid Rendezvous project lands the first spacecraft on an asteroid. 

2004
APL’s Messenger spacecraft

APL’s Messenger spacecraft launches on its quest to become the first spacecraft to orbit Mercury.  

2011
Adam Riess

JHU astrophysicist Adam Riess wins the Nobel Prize in physics for his leading role in dark energy research. 

2014

JHU bioethicist Jeffrey Kahn leads a committee that issues ethical guidelines for long duration spaceflight in a report commissioned by NASA.

"Astronauts put their lives and health at great risk for their country and humankind. Our report builds on NASA's work and confirms the ethical imperative to protect astronauts' health while fulfilling the agency's mission of exploration." - Jeffrey Kahn, Director of the JHU Berman Institute of Bioethics Learn More
2015
Members of the New Horizons science team react to seeing the spacecraft's last and sharpest image of Pluto at the Johns Hopkins University Applied Physics Laboratory.

APL designs, builds, and operates the New Horizons spacecraft, which completes a flyby of Pluto, providing images from the outer reaches of the solar system.

2018
Parker Solar Probe is mounted atop its third-stage rocket motor with half of the 62.7-foot fairing that will encapsulate it.

APL launches the Parker Solar Probe, a NASA spacecraft that provides humanity’s closest encounter with the sun. 

2021
This landscape of mountains and valleys speckled with glittering stars is actually the edge of a nearby, young, star-forming region called NGC 3324 in the Carina Nebula. Captured in infrared light by NASA’s James Webb Space Telescope, this image reveals for the first time previously invisible areas of star birth.

The James Webb Space Telescope launches, 20 years after the Space Telescope Science Institute is selected to oversee its science and mission operations. 

2022
NASA's Dart spacecraft

APL builds and operates NASA’s DART spacecraft, which successfully alters an asteroid’s orbit. 

2025

JHU’s Applied Physics Laboratory prepares to launch IMAP, a spacecraft that aims to understand the outer edges of our solar system.  

"We'll get an unprecedented look at the charged and uncharged particles of different energies streaming from the sun near Earth and far, far away, at the outer edges of the heliosphere." - Matina Gkioulidou, space physicist at the Johns Hopkins Applied Physics Laboratory Learn More

Looking Forward

In 2027, with the help of Johns Hopkins Applied Physics Laboratory, NASA’s Artemis III mission will return humans to the moon for the first time in 50 years. They will build a lunar science and industrial basecamp on the far side of the moon, later using the basecamp as a launchpad for exploring Mars—and establishing human colonies beyond Earth in our solar system.

And, estimated to launch in 2028, the Dragonfly robotic rotorcraft will explore the surface and subsurface of Titan, the largest moon orbiting the planet Saturn. APL will build and operate the vehicle which is equipped with cameras, sensors, and samplers to investigate the complex chemistry which is the precursor to life. It will examine areas of Titan known to contain organic materials that may have previously mixed with liquid water now frozen on the icy surface.
