Fifty years ago, Apollo 15 lifted off from
Kennedy Space Center, sending Commander David R. Scott, Command Module Pilot
Alfred M. Worden, and Lunar Module Pilot James B. Irwin on the first of
three Apollo “J” missions. These missions gave
astronauts the opportunity to explore the Moon for longer periods using
upgraded and more plentiful scientific instruments than ever before. Apollo 15
was the first mission where astronauts used the Apollo Lunar Surface Drill (ALSD) and the Lunar Roving Vehicle
(LRV).
Scott and Irwin would land on the Moon and use the ALSD at the site where they set up
several scientific instruments during the nearly 67 hours they were on the
surface of the Moon. The tool was a rotary-percussive drill that used a
combined motion that hammered a rotating drill bit into the surface to make a
hole. The overall purpose of gathering core samples was part of NASA’s lunar
geology studies to learn more about the composition of the Moon and discover
more about its history by looking at different kinds of rocks, including some
from below the surface.
Now, NASA is going back to the Moon as part of the agency’s Artemis missions and has a
new drill headed to the lunar surface as a commercially delivered payload via
the Commercial Lunar
Payload Services initiative. The Regolith and Ice
Drill for Exploring New Terrain (TRIDENT) is key to locating ice and other
resources on the Moon.
“Honeybee Robotics designed the TRIDENT drill for NASA to sample lunar
regolith,” said Amy Eichenbaum, the Polar Resources Ice Mining Experiment-1
(PRIME-1) deputy project manager. “TRIDENT will help understand the physical
properties of the lunar regolith while also allowing analysis of the resources
present in samples taken from various depths.”
TRIDENT is also a rotary-percussive drill, but one major difference between
it and its Apollo counterpart is that TRIDENT does not need astronauts to
operate it manually. Honeybee Robotics originally partnered with NASA through
the Small Business Innovation
Research program, a highly competitive program that
encourages small businesses to engage in federal research.
Polar Resources Ice
Mining Experiment-1 (PRIME-1) will be the first
in-situ resource utilization demonstration on the Moon. For the first time,
NASA will robotically sample and analyze for ice from below the surface.
PRIME-1 will use TRIDENT to drill in a single location at a site with a high
likelihood of having water – whether in liquid or ice form. It will drill down
about 3 feet (1 meter) below the surface, each time bringing up samples that
NASA will analyze with a scientific instrument – the Mass Spectrometer observing lunar operations (MSolo).

“MSolo will measure water ice and other volatiles released from the
sample brought to the surface by the TRIDENT drill,” said Dr. Janine Captain,
the principal investigator for MSolo. “These measurements will help us start to
understand the distribution of resources on the lunar surface, a key to
enabling a long-term presence on the Moon.”
Apollo 15 landed near the Hadley Rille, a long, deep channel-like gorge
in the Moon’s surface, which was at the base of the Apennines Mountains to the
north of the Moon’s equator. PRIME-1’s destination is the Moon’s South Pole -
new territory far from all the Apollo landing sites – a location very
interesting because NASA has previously detected water there from space.
However, gathering more accurate data requires PRIME-1, like ALSD, to land and
drill into the surface to examine what is there.

What PRIME-1 discovers will help to update resource models for where
explorers are most likely to find water on the Moon. About a year after the
PRIME-1 mission, NASA will send an exploratory rover – Volatiles Investigating Polar Exploration Rover, or
VIPER – to the surface. VIPER is NASA’s first mobile
robotic mission to the Moon, and will carry a TRIDENT drill and scientific
instruments that enable it to directly analyze water ice on the surface and
subsurface of the Moon at varying depths and temperature conditions. VIPER will
explore multiple sites on the lunar South Pole for about 100 days.
PRIME-1 and VIPER will build upon the legacy of Apollo 15 by using drills
and rovers, allowing NASA the chance to look below the surface and detect what
is there. Much like Apollo 15, NASA is preparing to send new capabilities to
the Moon that will enable people to stay there for longer than ever before,
because learning how to find and use water is a key to living and working on
the Moon and other deep space destinations.
“The Apollo missions first introduced the concept of drilling to provide
subsurface understanding of a foreign world,” said Dan Andrews, VIPER Project
Manager. “PRIME-1 and VIPER will expand the state of the art as we look to a
future of sustainable exploration and learning how to live off the land.”
