NASA Welcomes Botswana as 68th Artemis Accords Signatory  

The Republic of Botswana signed the Artemis Accords Thursday during a ceremony hosted by NASA at the agency’s headquarters in Washington, becoming the sixth African nation to join a growing community of nations committed to the peaceful, transparent, and responsible exploration of space.

“It is my privilege to welcome Botswana as the newest signatory of the Artemis Accords,” said NASA Deputy Administrator Matt Anderson. “Today marks an important milestone in our international partnership and in the continued growth of the Artemis community. Botswana joins at an important moment. Earlier this month, we announced the crew of Artemis III and, as we speak, their spacecraft is being assembled as they prepare to play their part in mankind’s greatest adventure.”

Botswana’s Minister of Communications and Innovation David Tshere signed on behalf of the country. U.S. Department of State Senior Advisor for Space Gregory Autry, and Mabedi Ngwenya, acting ambassador of the Republic of Botswana to the United States, also participated in the ceremony.

“Botswana like many countries, we have interest in space exploration, found it important to become a signatory to the Artemis Accords to promote the safe, transparent, and sustainable civil space exploration, and to advance international cooperation, and a shared framework for responsible activities in the space,” said Tshere.

This new chapter builds on Botswana’s long history of collaboration with the United States in space-based Earth observation. In the early 1970s, Botswana participated in the satellite program later known as Landsat, joining dozens of other nations in pioneering satellite-based environmental observation. Botswana marked another milestone with the launch of its first Earth observation satellite, Botswana Satellite 1, in March 2025, aboard a SpaceX Falcon 9. 

In 2020, during the first Trump Administration, the United States, led by NASA and the State Department, joined with seven other founding nations to establish the Artemis Accords, responding to the growing interest in lunar activities by both governments and private companies. The Artemis Accords introduced the first set of practical principles aimed at enhancing the safety and coordination between like-minded nations as they explore the Moon, Mars, and beyond.  

Signing the Artemis Accords means committing to explore peaceably and transparently, to render aid to those in need, to enable access to scientific data that all of humanity can learn from, to ensure activities do not interfere with those of others, and to preserve historically significant sites and artifacts by developing best practices for space exploration for the benefit of all. 

More countries are expected to sign the Artemis Accords in the months and years ahead, as NASA continues its work to establish a safe, peaceful, and prosperous future in space.

NASA Selects Rocket Lab to Launch Sun, Earth Science Missions

NASA has selected Rocket Lab to provide the launch service for both the agency’s PolSIR (Polarized Submillimeter Ice-cloud Radiometer) and Total and Spectral Solar Irradiance Sensor-2 (TSIS-2) missions.

The two selections are part of NASA’s Venture-Class Acquisition of Dedicated and Rideshare (VADR) launch services contract. This contract allows the agency to award fixed-price indefinite-delivery/indefinite-quantity launch service task orders during VADR’s 10-year ordering period, with a maximum total contract value of $300 million.

The PoISIR mission will help provide a better understanding of ice clouds that form at high altitudes throughout tropical and subtropical regions. Rocket Lab will launch PolSIR aboard two of its dedicated Electron rockets no earlier than June 2027 from Launch Complex 1 in Mahia, New Zealand.

Consisting of two small satellites, both of PoISIR’s 16U CubeSats have a scientific instrument designed to measure a specific spectrum of electromagnetic radiation, which will determine how the amount of ice in tropical clouds rises and falls during the day, as well as how the ice changes connect to larger storms. The instruments also will help determine how ice clouds affect sunlight and heat radiation throughout the day. The pair of CubeSats will fly in orbits separated by several hours to observe the pattern of cloud ice content changes over a day. This information will help researchers make more accurate weather predictions.

The PolSIR mission’s principal investigator is Vanderbilt University in Nashville. Science operations will be conducted by the Space Science and Engineering Center at the University of Wisconsin in Madison. The two spacecraft are being built by Blue Canyon Technologies.

The TSIS-2 mission will measure the Sun’s energy input to Earth. The spacecraft will provide critical data for understanding our planet’s ocean currents, seasons, and weather. The mission will continue NASA’s work to study and protect our home planet by providing insights that can only be gathered from space. Rocket Lab will launch TSIS-2 aboard an Electron rocket in early 2027 from Launch Complex 1 in Mahia.

The satellite measures Earth’s solar energy input, both the total irradiance, which is the Sun’s overall brightness at the top of Earth’s atmosphere, and the spectral irradiance, or how that energy is distributed across ultraviolet, visible, and infrared wavelengths. The satellite’s two instruments, the Total Irradiance Monitor and the Spectral Irradiance Monitor, are similar to those used for TSIS-1. Together, they cover a wavelength range that includes 96% of the energy in the solar spectrum. While TSIS‑1 works from the International Space Station, TSIS‑2 will operate from a free‑flying spacecraft.

Managed by NASA’s Goddard Space Flight Center in Greenbelt, Maryland, TSIS-2 includes instruments provided by the Laboratory for Atmospheric and Space Physics at the University of Colorado, Boulder, and the spacecraft is provided by General Atomics – Electromagnetic Systems.

NASA’s Launch Services Program, based at the agency’s Kennedy Space Center in Florida, manages the VADR contract.

Millions of Stars in Cigar Galaxy

NASA’s James Webb Space Telescope recently observed edge-on starburst galaxy Messier 82 (M82), nicknamed the Cigar Galaxy. Webb’s new view of M82, added to archival data from NASA’s Hubble Space Telescope, gives us a more complete picture of this starburst galaxy. Because Webb can see infrared light, it is able to peer through clouds of dust and gas to see the shape of this edge-on galaxy, as well as approximately 16.5 million of its stars.

M82’s rapid star formation, thought to be the result of its merger with another galaxy, will only be a (relatively) brief period in its history. Ironically, the extreme star formation is causing plumes of material to be ejected above and below the disk of the galaxy – something that will disrupt future stellar birth.

A Turquoise Tint for the Black Sea

The Black Sea sits at the boundary between Europe and Asia and connects to the Mediterranean Sea via a chain of waterways. Its surface often appears dark, but each spring and summer it transforms into a striking expanse of swirling turquoise. The OCI (Ocean Color Instrument) on NASA’s PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) satellite captured this image (above) of the colorful waters on June 22, 2026. 

The turquoise color is likely caused by coccolithophores, a type of phytoplankton covered with calcium carbonate plates that can give surface waters a milky-blue appearance. These types of phytoplankton tend to dominate in late spring and early summer. Other times of the year, diatoms—a type of microscopic algae with silica shells—can become more prevalent, and they tend to darken the water rather than brighten it.   

The Bosphorus, the narrow strait running through Istanbul that connects the Black Sea with the Sea of Marmara, also turned turquoise. An astronaut aboard the International Space Station photographed the strait on May 27, 2026 (below), about a month before the PACE image, capturing blooming phytoplankton as it traced currents on both sides of the waterway. (Note that north is oriented toward the bottom of the frame.)

Though coccolithophores are microscopic, they become so abundant during a bloom that they become visible from space. This makes remote sensing a useful tool for researchers studying bloom dynamics in regions where direct sampling is limited. Beyond their visibility, these blooms also contribute to the ocean’s carbon cycle. When they die, some of the carbon they’ve taken up sinks to the seafloor, where it can remain stored for long periods of time.

NASA Earth Observatory image by Michala Garrison, using PACE data from NASA EOSDIS LANCE and GIBS/Worldview and the NASA Ocean Biology Distributed Active Archive Center OB.DAAC. Astronaut photograph ISS074-E-619520 was acquired on May 27, 2026, with a Nikon Z9 digital camera using a focal length of 50 millimeters. It is provided by the ISS Crew Earth Observations Facility and the Earth Science and Remote Sensing Unit at NASA Johnson Space Center. The image was taken by a member of the Expedition 74 crew. The image has been cropped and enhanced to improve contrast, and lens artifacts have been removed. The International Space Station Program supports the laboratory as part of the ISS National Lab to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public, and to make those images freely available on the Internet. Additional images taken by astronauts and cosmonauts can be viewed at the NASA/JSC Gateway to Astronaut Photography of Earth. Story by Kathryn Hansen.
