NASA Selects New Crew for Next Simulated Mars Journey

Lee esta historia en español aquí.

NASA has selected a new crew of four volunteers to participate in a simulated mission to Mars within a habitat at the agency’s Johnson Space Center in Houston.

Jason Lee, Stephanie Navarro, Shareef Al Romaithi, and Piyumi Wijesekara will step into the agency’s Human Exploration Research Analog, or HERA, on Friday, May 10. Once inside, the team will live and work like astronauts for 45 days. The crew will exit the facility on June 24 after they “return” to Earth. Jose Baca and Brandon Kent are this mission’s alternate crew members.

Space Force funds $35M institute for versatile propulsion at U-M

This sounds very promising! The researchers are investigating the use of nuclear microreactors to power faster and more efficient electric propulsion systems.☢️🚀

To develop spacecraft that can “maneuver without regret,” the U.S. Space Force is providing $35 million to a national research team led by the University of Michigan. It will be the first to bring fast chemical rockets together with efficient electric propulsion powered by a nuclear microreactor.

The newly formed Space Power and Propulsion for Agility, Responsiveness and Resilience Institute involves eight universities, and 14 industry partners and advisers in one of the nation’s largest efforts to advance space power and propulsion, a critical need for national defense and space exploration.

Right now, most spacecraft propulsion comes in one of two flavors: chemical rockets, which provide a lot of thrust but burn through fuel quickly, or electric propulsion powered by solar panels, which is slow and cumbersome but fuel efficient. Chemical propulsion comes with the highest risk of regret, as fuel is limited. But in some situations, such as when a collision is imminent, speed may be necessary.

Airbus Successfully Completes First Lakota UH-72 Drone Helicopter Demo for US Marine Corps

Airbus U.S. Space & Defense announced on October 15, 2024, the successful completion of the first demonstration of the Lakota UH-72 drone helicopter for the U.S. Marine Corps, conducted at Marine Corps Air Station New River and Camp Lejeune. This demonstration showcased the capabilities of the Aerial Logistics Connector (ALC) system, designed to enhance logistical support in dispersed and challenging environments. As an autonomous platform, the Lakota UH-72 ensures a continuous supply flow without relying on traditional transportation methods, which are often vulnerable or limited.

Crew-8 Awaits Splashdown; Expedition 72 Stays Focused on Science

Four International Space Station crew members continue waiting for their departure date as mission managers monitor weather conditions off the coast of Florida. The rest of the Expedition 72 crew on Monday stayed focused on space biology and lab maintenance aboard the orbital outpost.

NASA and SpaceX mission managers are watching unfavorable weather conditions off the Florida coast right now for the splashdown of the SpaceX Crew-8 mission with NASA astronauts Matthew Dominick, Mike Barratt, and Jeanette Epps, and Roscosmos cosmonaut Alexander Grebenkin. The homebound quartet spent Monday mostly relaxing while also continuing departure preps. In the meantime, mission teams are awaiting the next weather briefing scheduled for Wednesday, Oct. 16, at 11 a.m. EDT, and are currently targeting Dragon Endeavour’s undocking for no earlier than 3:05 a.m. on Friday, Oct. 18. The Crew-8 foursome is in the seventh month of their space research mission that began on March 3.

The other seven orbital residents will stay aboard the orbital outpost until early 2025. NASA astronaut Don Pettit is scheduled to return to Earth first in February with Roscosmos cosmonauts Alexey Ovchinin and Ivan Vagner aboard the Soyuz MS-26 crew ship. Next, station Commander Suni Williams and Flight Engineer Butch Wilmore are targeted to return home aboard SpaceX Dragon Freedom with SpaceX Crew-9 Commander Nick Hague, all three NASA astronauts, and Roscosmos cosmonaut Aleksandr Gorbunov.

What happens to the Climate when Earth Passes Through Interstellar Clouds?

Noctilucent clouds were once thought to be a fairly modern phenomenon. A team of researchers recently calculated that Earth and the entire solar system may well have passed through two dense interstellar clouds, causing global noctilucent clouds that may have driven an ice age.

The event is thought to have happened 7 million years ago and would have compressed the heliosphere, exposing Earth to the interstellar medium.

Interstellar clouds are vast regions of gas and dust between the stars within galaxies. They are mostly made up of hydrogen along with a little helium and trace elements of heavier elements.
