Nasa has delayed putting astronauts back on the moon until 2025 at the earliest, missing the deadline set by the Trump administration.
The space agency had been aiming for 2024 for the first moon landing by astronauts in a half century.
In announcing the delay on Tuesday, the Nasa administrator, Bill Nelson, said Congress had not provided enough money to develop a landing system for its Artemis moon program and more money was needed for its Orion capsule. In addition, a legal challenge by Jeff Bezos’s rocket company, Blue Origin, stalled work for months on the Starship lunar landing system under development by Elon Musk’s SpaceX.
International isolation experiment SIRIUS-21 to simulate the flight and landing on the moon started on Thursday in Moscow, a Sputnik correspondent reported from the Institute of Biomedical Problems (IBMP) of the Russian Academy of Sciences.
Six people went on a conditional trip to the moon: Oleg Blinov, an instructor of the Cosmonaut Training Center; Viktoria Kirichenko, a surgeon at the IBMP; Ekaterina Kariakina, ex-flight attendant of the Nordwind airline, and now a junior researcher at the Institute of International Biological Problems; William Brown, a US bachelor of Russian Language and Literature; Ashley Kowalski, a representative of the command US space systems; and UAE test astronaut Saleh Omar Al Ameri.
They will have to live together for 240 days in a simulator of a spacecraft - a ground-based test complex in Moscow. The task of the "crew" is to simulate the flight, landing on the Moon and work on its surface.
The SIRIUS project (Scientific International Research In Unique Terrestrial Station) is carried out jointly by IBMP and NASA in cooperation with space agencies of Russia, ESA, Germany, France, the United Arab Emirates, space industry enterprises with the participation of experts from Russia, the US, Germany, France, Italy, Belgium, Japan, Canada and other countries.
SIRIUS includes a series of isolation experiments. Experiments have already been carried out with a duration of 17 days in November 2017 and four months in 2018-2019. Until 2028, it is planned to conduct three year-long experiments. The first of them will take place in 2022-2023.
NASA's Mars helicopter Ingenuity has flown for the 15th time on Mars, starting a journey back to its starting point for future missions in a new direction.
The latest flight, over the weekend, was relatively short -- at just 128 seconds -- and was designed in part to further test flight conditions at Jezero Crater now that summer has arrived.
"Ingenuity opportunistically took images of science interest and they'll be processed soon," NASA posted on Twitter.
Flight controllers plan a series of flights in coming weeks to send the Mars helicopter Ingenuity back to where it began its adventure near the Perseverance rover's landing site.
"Ingenuity is ready to begin the journey back to the Wright Brothers Field at the Octavia E. Butler landing site, before venturing beyond," NASA Ingenuity team leader Teddy Tzanetos said earlier in a blog post on NASA's website.
Wright Brothers Field is what NASA named the location of Ingenuity's first five flights that demonstrated such a craft could fly in the thin Martian atmosphere.
Since then, NASA has used Ingenuity to scout for its big buddy on Mars, the Perseverance rover. Both robotic explorers were launched together from Florida n July 2020.
The helicopter generally has flown ahead of the rover to photograph routes and interesting rocks Perseverance could sample with its drill.
Ingenuity's total flight distance is approaching 10,000 feet, or close to 2 miles, but sometimes it has flown a circuitous route to capture images, so the journey back to the starting point will be far less distance than the trip out.
The rover and helicopter went south from their landing site to investigate some outcrops, but NASA now wants to explore north and west of the starting point. The mission is focused on finding possible signs of ancient life.
Once Ingenuity and Perseverance return to their landing site, the tiny, 4-pound drone will "join Perseverance in the trek north ... before traveling west to reach the Jezero ancient river delta."
NASA also is preparing a flight software upgrade which "will potentially enable new navigation capabilities onboard," according to Tzanetos' blog post.
Mielenkiintoinen uusi laukaisujärjestelmä josta 1. testi on nyt tehty. Voisi olla hyödyllinen myös kuun pinnalta toimittaessa missä ilmakehä ei aiheuta ongelmia.

Eikös sellaisen roinan pitäisi pikkuhiljaa laskeutua lähemmäs maata? Jos ohjuksella on osuttu vanhaan satelliittiin luulisi että räjähdyksessä sirpaleita lentelisi vähän joka suuntaan.

Muita ongelmia tuosta romusta saattaa toki syntyä.
Kyllähän se laskeutuu, ja lisää tietoa radasta kaivattaisiin. Nopea arvioni vaan oli että radat ovat niin kaukana toisistaan että riski avaruusasemalle on mitätön. Se kuitenkin jossain määrin perustui tuon Kosmos 1408:n ilmoitettuun rataan, ja se todennäköisesti oli vanhaa tietoa. Inklinaatiot poikkeavat edelleen niin paljon että törmäys on äärimmäisen epätodennäköinen.Eikös sellaisen roinan pitäisi pikkuhiljaa laskeutua lähemmäs maata?
