Swarm of Tiny Swimming Robots Could Look for Life on Distant Worlds
In the Sensing With Independent Micro-Swimmers (SWIM) concept, illustrated here, dozens of small robots would descend through the icy shell of a distant moon via a cryobot – depicted at left – to the ocean below. The project has received funding from the NASA Innovative Advanced Concepts program. (Credits: NASA/JPL-Caltech)

A concept in development at NASA’s Jet Propulsion Laboratory would allow potential planetary missions to chase interesting clues in subsurface oceans.

PASADENA, Calif. (NASA PR) — Someday, a swarm of cellphone-size robots could whisk through the water beneath the miles-thick icy shell of Jupiter’s moon Europa or Saturn’s moon Enceladus, looking for signs of alien life. Packed inside a narrow ice-melting probe that would tunnel through the frozen crust, the tiny robots would be released underwater, swimming far from their mothercraft to take the measure of a new world.

NASA Begins Assembly of Europa Clipper Spacecraft

Science instruments and other hardware for the spacecraft will come together in the mission’s final phase before a launch to Jupiter’s icy moon Europa in 2024.

PASADENA, Calif. (NASA PR) — When it’s fully assembled, NASA’s Europa Clipper will be as large as an SUV with solar arrays long enough to span a basketball court – all the better to help power the spacecraft during its journey to Jupiter’s icy moon Europa. And just about every detail of the spacecraft will have been hand-crafted.

NASA Selects Futuristic Space Technology Concepts for Early Study

WASHINGTON (NASA PR) — An astronaut steps into a body scanner and, hours later, walks on Mars in a custom-made spacesuit, breathing oxygen that was extracted from Mars’ carbon dioxide-rich atmosphere. On Venus, an inflatable bird-like drone swoops through the sky, studying the planet’s atmosphere and weather patterns. Ideas like these are currently science fiction, but they could one day become reality, thanks to a new round of grants awarded by NASA.

Hubble Finds Evidence of Persistent Water Vapor in One Hemisphere of Europa
This photograph of the Jovian moon Europa was taken in June 1997 at a range of 776,700 miles by NASA’s Galileo spacecraft. Slightly smaller than Earth’s moon, Europa has a very smooth surface and the solid ice crust has the appearance of a cracked eggshell. The interior has a global ocean with more water than found on Earth. It could possibly harbor life as we know it. Hubble Space Telescope observations of Europa have revealed the presence of persistent water vapor in its very tenuous atmosphere. Hubble observations, spanning 1999 to 2015, find that water vapor is constantly being replenished throughout one hemisphere of the moon. This is a different finding from Hubble’s 2013 observations that found localized water vapor from geysers venting from its subsurface ocean. This water vapor comes from a different process entirely. Sunlight causes the surface ice to sublimate, transitioning directly into gas. This color composite Galileo view combines violet, green, and infrared images. The view of the moon is shown in natural color (left) and in enhanced color designed to bring out subtle color differences in the surface (right). The bright white and bluish part of Europa’s surface is composed mostly of water ice, with very few non-ice materials. Long, dark lines are fractures in the crust, some of which are more than 1,850 miles long. The Galileo mission ended on Sept. 21, 2003, when the spacecraft was intentionally commanded to dive into Jupiter’s atmosphere, where it was destroyed. However, to this day scientists continue to study the data it collected. The Jet Propulsion Laboratory (JPL) in Pasadena, California managed the Galileo mission for NASA’s Office of Space Science, Washington, DC. JPL is an operating division of California Institute of Technology (Caltech). This image and other images and data received from Galileo are posted on the Galileo mission home page. Background information and educational context are also available for the images. (Credits: NASA, NASA-JPL, University of Arizona)

GREENBELT, Md. (NASA PR) — NASA’s Hubble Space Telescope observations of Jupiter’s icy moon Europa have revealed the presence of persistent water vapor – but, mysteriously, only in one hemisphere.

A Few Steps Closer to Europa: Spacecraft Hardware Makes Headway
Contamination control engineers in a clean room at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, evaluate a propellant tank before it is installed in NASA’s Europa Clipper spacecraft. The tank is one of two that will be used to hold the spacecraft’s propellant. It will be inserted into the cylinder seen at left in the background, one of two cylinders that make up the propulsion module. (Credit: NASA/GSFC Denny Henry)

Take a closer look at the complex choreography involved in building NASA’s Europa Clipper as the mission to explore Jupiter’s moon Europa approaches its 2024 launch date.

PASADENA, Calif. (NASA PR) – The hardware that makes up NASA’s Europa Clipper spacecraft is rapidly taking shape, as engineering components and instruments are prepared for delivery to the main clean room at the agency’s Jet Propulsion Laboratory in Southern California. In workshops and labs across the country and in Europe, teams are crafting the complex pieces that make up the whole as mission leaders direct the elaborate choreography of building a flagship mission.

Surface of Jupiter’s Moon Europa Churned by Small Impacts

Jupiter’s moon Europa and its global ocean may currently have conditions suitable for life. Scientists are studying processes on the icy surface as they prepare to explore.

PASADENA, Calif. (NASA PR) — It’s easy to see the impact of space debris on our Moon, where the ancient, battered surface is covered with craters and scars. Jupiter’s icy moon Europa withstands a similar trouncing – along with a punch of super-intense radiation. As the uppermost surface of the icy moon churns, material brought to the surface is zapped by high-energy electron radiation accelerated by Jupiter.

NASA FACT SHEET
FY 2022 Budget Request
Science
($ Millions)

NASA’s Science budget, managed by the Science Mission Directorate, includes five major science areas as well as the James Webb Space Telescope which is funded separately from Astrophysics. These areas include:

  • Earth Science to enhance understanding of Earth systems and to observe the effects of climate change. The Budget invests heavily in climate and applications research, begins formulation of the first four Designated Observable missions, and initiates the Earth System Explorers program (consistent with Decadal Survey recommendations). The Budget also supports the ongoing development of the Earth System Observatory including PACE, CLARREO Pathfinder, NISAR, SWOT, and Landsat 9.
