From the iconic image of Earthrise taken by Apollo 8 crew, to the famous Pale Blue Dot image of Earth snapped by Voyager I spacecraft, to state-of-the-art observations of our planet by new satellites such as PACE (Plankton, Aerosol, Cloud, ocean Ecosystem), NASA has given us novel ways to see our home. This Earth Day, NASA is sharing how — by building on decades of innovation—we use the unique vantage point of space to observe and understand our dynamic planet in ways that we cannot from the ground.

NASA has been observing Earth from space for more than 60 years, with cutting-edge scientific technology that can revolutionize our understanding of our home planet and provide benefits to all humanity. NASA observations include land data that helps farmers improve crop production, research on the air we breathe, and studies of atmospheric layers high above us that protect every living thing on the planet.

“NASA Science delivers every second of every day for the benefit all, and it begins with how we observe our home planet from the unique vantage point of space,” said Nicky Fox, associate administrator, Science Mission Directorate at NASA Headquarters in Washington. “Our satellites, Mars rovers, astronauts and other NASA Science missions send back beautiful images of our planet, from the smallest of plankton to the pale blue dot, to help give us a comprehensive, detailed view of our home that we especially celebrate each Earth Day.”

NASA data and tools are vital to federal, state, local, and international governments to monitor and manage land, air, and water resources. From mapping the ocean floor to finding critical mineral deposits to alerting land managers when fire risk is high, NASA’s data and information informs nearly every aspect of our economy and our lives.

“Another way NASA celebrates Earth Day is by sharing information about how our science benefits the entire nation, such as by providing U.S. farmers and ranchers with ongoing measurements of water, crop health, wildfire predictions, and knowledge of what is being grown around the world,” said Karen St. Germain, director of NASA’s Earth Science Division at the agency’s headquarters in Washington. “This data informs field level farming and ranching decisions with impact felt as far as the commodity-trading floor and our grocery stores.”

Next up for NASA’s work to help mitigate natural disasters is a mission called NISAR (NASA-ISRO Synthetic Aperture Radar) which is a partnership between NASA and ISRO (India Space Research Organization). NISAR, which is targeted to launch later this year, will measure land changes from earthquakes, landslides, and volcanos, producing more NASA science data to aid in disaster response. The mission’s radar will detect movements of the planet’s surface as small as 0.4 inches over areas about the size of half a tennis court. By tracking subtle changes in Earth’s surface, it will spot warning signs of imminent volcanic eruptions, help to monitor groundwater supplies, track the melt rate of ice sheets tied to sea level rise, and observe shifts in the distribution of vegetation around the world. 

From our oceans to our skies, to our ice caps, to our mountains, and to our rivers and streams, NASA’s Earth observations enhance our understanding of the world around us and celebrate the incredible planet we call home.

Earth planning date: Friday, April 18, 2025

As the APXS operations person today, I was hopeful that we could plan a compositional measurement after brushing one of the bedrock blocks in front of the rover. However, it soon became clear that the rover was not on stable enough ground to safely unstow the arm and place APXS and MAHLI. Silver linings though; by not having any arm movement in this plan, which requires significant energy, we were able to conserve power for what we hope will be a busy week of upcoming science activities as we drive towards our next high priority area of interest – the so-called boxwork formations. These are large resistant ridges identified from orbit, which may be the result of fracturing, fluid flow and alteration within the sulfate unit that we are traversing through. We plan to image them on approach to gain insights into their context.

Despite the loss of arm activities, we still have plenty of interesting observations planned for this 3-sol weekend. ChemCam will fire its laser at two separate rock targets, “Santa Ynez” and “Cahuilla”, which will also be captured with Mastcam documentation images. The targets are on two different bedrock blocks with the “Cahuilla” raster focused on a thin resistant layer. ChemCam will also use its remote imaging capabilities to obtain mosaics of the “Texoli” butte and another interesting feature, “Torote Bowl”. Mastcam will capture mosaics of “San Gabriel River” (an apparent angular contact) and of some sand troughs surrounding many of the bedrock blocks in this region. An image will also be acquired of a small, grey float pebble, “Piru Creek.”

The environmental science group was also able to plan a number of activities to catch up on their regular cadence, which has been impacted by the recent power constraints. We are acquiring Navcam line of sight observations (x2), suprahorizon movies (x2), a zenith movie and a 360 degree sky survey, as well as a Mastcam sky survey. Coordinated ChemCam passive sky and APXS atmospheric observations are also planned.

There is a ~19 m drive planned through this tricky terrain that will hopefully set us up for arm activities (APXS and MAHLI) in our new workspace next week. The plan is completed with standard RAD, DAN and REMS activities, as well as two MARDI images to record the terrain beneath the rover in the current and new workspace.

NASA’s SpaceX CRS-32: Dragon Launches at 4:15 a.m. EDT

NASA’s SpaceX CRS-32: Dragon Launches at 4:15 a.m. EDT

The SpaceX Falcon 9 rocket carrying the Dragon spacecraft lifts off from Launch Complex 39A at NASA’s Kennedy Space Center in Florida on Monday, April 21, on the company’s 32nd commercial resupply services mission for the agency to the International Space Station. Liftoff was at 4:15 a.m. EDT.
NASA

At 4:15 a.m. EDT, about 6,700 pounds of scientific investigations and cargo launched to the International Space Station on the SpaceX Dragon spacecraft for the company’s 32nd commercial resupply services mission for NASA. The spacecraft lifted off on a SpaceX Falcon 9 rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. 
 
About 9 minutes after launch, Dragon will separate from the rocket’s second stage, open its nosecone, and begin a carefully choreographed series of thruster firings to reach the space station. 
 

Dragon will arrive at the orbiting outpost at 8:20 a.m. Tuesday, April 22, and dock autonomously to the zenith, space-facing port of the space station’s Harmony module. 

NASA will provide live coverage of the spacecraft’s arrival beginning at 6:45 a.m. April 22 on NASA+. Learn how to watch NASA content through a variety of platforms.

Following the successful launch of NASA’s SpaceX 32nd Commercial Resupply Services mission, new scientific experiments and supplies are bound for the International Space Station.

The SpaceX Dragon spacecraft, carrying approximately 6,700 pounds of cargo to the orbiting laboratory for NASA, lifted off at 4:15 a.m. EDT Monday, on the company’s Falcon 9 rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida.

Live coverage of the spacecraft’s arrival will begin at 6:45 a.m., Tuesday, April 22, on NASA+. Learn how to watch NASA content through a variety of platforms.

The spacecraft is scheduled to autonomously dock at approximately 8:20 a.m. to the zenith, or space-facing, port of the space station’s Harmony module.

The resupply mission will support dozens of research experiments during Expedition 73. Along with food and essential equipment for the crew, Dragon is delivering a variety of science experiments, including a demonstration of refined maneuvers for free-floating robots. Dragon also carries an enhanced air quality monitoring system that could help protect crew members on exploration missions to the Moon and Mars, and two atomic clocks to examine fundamental physics concepts, such as relativity, and test global synchronization of precision timepieces.

These are just a sample of the hundreds of investigations conducted aboard the orbiting laboratory each year in the areas of biology and biotechnology, physical sciences, and Earth and space science. Such research benefits humanity and helps lay the groundwork for future human exploration through the agency’s Artemis campaign, which will send astronauts to the Moon to prepare for future missions to Mars.

The Dragon spacecraft is scheduled to remain at the orbiting laboratory until May, when it will depart and return to Earth with time-sensitive research and cargo, splashing down off the coast of California.
