The Moon and Mars are the next big topics for exploration in the coming years. The USA is preparing the next steps towards the Moon and Mars with its Artemis programme. In order to become part of this important stage in space history, on 14 September 2023, Member of the DLR Executive Board and Director General of the German Space Agency at the German Aerospace Center, Walther Pelzer signed the A New clues to the nature of elusive dark matter

A team of international researchers, led by experts at the University of Adelaide, has uncovered further clues in the quest for insights into the nature of dark matter.
"Dark matter makes up 84 per cent of the matter in the universe but we know very little about it," said Professor Anthony Thomas, Elder Professor of Physics, University of Adelaide.

SpaceX test fires a Raptor engine, simulating a lunar landing
Monday, 18 September 2023 18:28 Write a comment
When NASA astronauts return to the surface of the moon in the Artemis III mission, the plan is to use a modified SpaceX Starship as their lunar lander. NASA announced last week that SpaceX has now demonstrated an important capability of the vacuum-optimized Raptor engine that will be used for the lander: an extreme cold start.
A test last month successfully confirmed the engine can be started in the frigid conditions of space, even when the vehicle has spent an extended time in space, where temperatures will drop lower than a shorter low-Earth orbit mission. The Raptor vacuum engine was chilled to mimic conditions after a long coast period in space, and then was successfully fired.
SpaceX has a video on X (formerly Twitter) showing the test firing.
NASA said that one challenge that differentiates Artemis missions from those in low Earth orbit is that the landers may sit in space without firing for an extended period of time, "causing the temperature of the hardware to drop to a level below what they would experience on a much shorter low Earth orbit mission.
Q&A: Decadal survey sets agenda for biological, physical sciences in space
Monday, 18 September 2023 18:04 Write a comment
The National Academies' latest decadal survey, "Thriving in Space," released Sept. 12, provides a roadmap for biological and physical sciences research, from the low orbit of Earth to the surface of Mars, through 2033.
Krystyn Van Vliet, vice president for research and innovation and a self-confessed "space geek," served as co-chair of the steering committee that produced the survey.
Van Vliet spoke with the Chronicle about her work on the project and its potential impact.
For the uninitiated, what is the decadal survey and why is it important?
Van Vliet: There are really two purposes. First, it's to give periodic input from the research community to the government as a signal for research priorities in the coming years. So it's a very science-driven effort where you gather input from people who have all kinds of interests and expertise and you say, "These are the big shots on goal that we should take as a country in the coming 10 years."
The second purpose is to develop a consensus report of a subset of that community, the steering committee that I co-chaired with Rob Ferl from the University of Florida, with input from hundreds of researchers who contributed input papers and dozens of people on the panels that worked on the report with us.
UFOs: What we will learn from the NASA panel investigating sightings
Monday, 18 September 2023 15:35 Write a comment
A committee set up by NASA has examined about 800 reports of unidentified anomalous phenomena (UAPs), or what most of us would call UFOs (unidentified flying objects). NASA defines these events as sightings "that cannot be identified as aircraft or known natural phenomena from a scientific perspective".
The creation of this committee shows that NASA is taking potential extraterrestrial events very seriously. On Wednesday, May 31 2023, the committee held its first public meeting to discuss what it is doing and what it has found so far, ahead of a full report later this year.
It revealed some reports are easy to explain as boats, planes or weather, some had comical, lunch-based origins, and only a few remain a mystery.
The committee is led by astrophysicist David Spergel and is made up of a team of experts ranging from university professors to a former astronaut. The study has been using declassified reports and images to try to explain some of the mysterious reports, which come from all sorts of sources including military personnel and commercial airline pilots.

Engineered compound shows promise in preventing bone loss in space
Monday, 18 September 2023 13:32 Write a comment
A study published in npj Microgravity, finds an engineered compound given to mice aboard the International Space Station (ISS) largely prevented the bone loss associated with time spent in space.
The study, led by a transdisciplinary team of professors at the University of California at Los Angeles (UCLA) and the Forsyth Institute in Cambridge, Massachusetts, highlight a promising therapy to mitigate extreme bone loss from long-duration space travel as well as musculoskeletal degeneration on Earth.
Microgravity-induced bone loss has long been a critical concern for long-term space missions. Decreased mechanical loading due to microgravity induces bone loss at a rate 12-times greater than on Earth. Astronauts in low Earth orbit may experience bone loss up to 1% per month, endangering astronaut skeletal health and increasing risk for fractures during long-duration spaceflight and later in life.
The current mitigation strategy for bone loss relies on exercise-induced mechanical loading to promote bone formation but is far from perfect for crew members spending up to six months in microgravity.
Exercise does not always prevent bone loss, takes up valuable crew time, and may be contraindicated for certain types of injuries.
