A Russian cargo spacecraft, Progress 94, launched toward the International Space Station on Sunday, March 22, carrying approximately 3 tons of food, propellant, and other essential supplies. The spacecraft is expected to dock with the ISS on Tuesday, March 24, and will spend about six months attached to the orbiting laboratory.
The Pentagon has awarded Rocket Lab a $190 million contract for 20 hypersonic test flights using its HASTE vehicle, with the goal of reaching speeds above Mach 5. This contract is part of the MACH-TB 2.0 program and will run over the next four years.
NASA"s Artemis II mission is on track to launch as early as April 1, with the crew set to arrive at Kennedy Space Center (KSC) for pre-launch quarantine. The mission marks a significant step towards returning humans to the lunar surface.
As NASA prepares to launch its Artemis 2 mission, nations participating in the Artemis Accords are working to establish key rules for operating on the moon, including emergency response protocols and addressing harmful interference. The unresolved issues highlight the complexity of international cooperation in space exploration.
The US Space Force has decided to launch the GPS III-8 satellite on a SpaceX Falcon 9 rocket instead of the originally planned United Launch Alliance Vulcan Centaur due to technical issues with the latter's solid rocket boosters. This change is significant as it affects the final mission in the GPS III line and highlights ongoing challenges with the Vulcan Centaur program.
Astronomers have discovered four new moons of Jupiter and 11 new moons of Saturn, bringing the total number of known moons in our solar system to 442. These small celestial bodies, with diameters averaging about 1.9 miles, were detected using large ground-based telescopes.
The US Department of Defense has awarded Rocket Lab a $190 million contract for 20 launches of its HASTE vehicle, a suborbital variant of the Electron rocket, to test hypersonic technologies. This partnership aims to accelerate the development of advanced aerospace capabilities through the TRMC MACH-TB program.
NASA"s Space Launch System (SLS) rocket has been transported to the launch pad at Kennedy Space Center in preparation for the upcoming Artemis 2 mission, which will send a crew of four astronauts on a lunar flyby. The mission is scheduled to launch no earlier than April 1, marking a significant milestone in NASA"s plans to return humans to the moon.
The Artemis 2 rocket has arrived back at the launch pad after addressing technical issues, with NASA aiming to launch the mission in less than two weeks. The mission will send astronauts around the moon, marking a significant step towards establishing a sustainable human presence on the lunar surface.
The NASA Artemis II mission is set to launch on April 1, 2026, sending four astronauts on a 10-day journey around the moon. The Space Launch System (SLS) rocket and Orion crew capsule are currently undergoing preparations for launch at the Kennedy Space Center.
NASA has lost contact with its MAVEN Mars spacecraft and is attempting to reestablish communication, with no signal detected since January 16. The agency remains hopeful in locating the spacecraft, deploying additional assets and utilizing the Curiosity rover to aid in the search.
The European Space Agency's Smile mission launched successfully on a Vega-C rocket from Europe's Spaceport in French Guiana, aiming to study Earth's response to solar wind and radiation. The mission will collect data on the planet's magnetic field and northern lights using advanced cameras.
The US Space Command will participate in a classified wargame with nearly 50 commercial space companies on March 23, 2026, in Colorado Springs, aiming to discuss threats and defense strategies in space. The exercise will focus on aligning military and commercial planning in space defense, particularly regarding the threat of weapons of mass destruction in space.
NASA"s Space Launch System (SLS) rocket and Orion spacecraft are set to return to the launch pad after repairs, with a planned launch attempt for the Artemis 2 mission scheduled for no earlier than April 1. The mission will see NASA astronauts fly around the Moon and splashdown in the Pacific Ocean, serving as a critical test flight for the Orion spacecraft.
Astronomers have discovered that exoplanet Kepler-51d, located 2,615 light years away, has an ultra-low density similar to cotton candy and is shrouded in a thick haze, making it difficult to study. The planet's unique characteristics have significant implications for our understanding of planetary formation and the search for life beyond Earth.
The European Space Agency (ESA) has reestablished contact with its Proba-3 Coronagraph spacecraft after a month of silence, marking a significant recovery in the mission to study the sun"s corona. The successful reconnection ensures the continuation of the Proba-3 mission, which relies on precise formation flying between the Coronagraph and Occulter satellites.
NASA's OSIRIS-REx mission has successfully analyzed samples of asteroid Bennu, revealing extensive networks of cracks within the rock particles, providing valuable insights into the asteroid's composition and thermal properties. This discovery sheds light on the asteroid's low thermal inertia and has significant implications for our understanding of asteroids and their behavior.
