Race back to space: Nations want a piece of the moon pie – CTech
The Artemis rocket, NASA’s behemoth Space Launch System (SLS) designed to take humanity back to the moon is scheduled for its first test launch on August 29th. Leading up to that launch, the megarocket began rolling out to its designated launchpad, 39B, earlier this week at an incredible speed of 1km/h. The launch, which will send an unmanned Orion space capsule into lunar orbit, is a test run for ultimately sending astronauts back for a lunar flyby in 2024 and a lunar landing as early as 2025.
That test launch, which is slated to last up to 42 days and should reach within 100 km of the lunar surface, will end only months before the 50th anniversary of the last time man was on the moon. The Apollo 17’s twelve-day mission returned home in mid-December 1972. In Greek mythology, Artemis is the twin sister of Apollo.
There will also be a Snoopy doll. Snoopy has long been associated with NASA’s space efforts, and this doll and other toys will be used as zero-gravity indicators to let researchers know when the rocket has entered zero gravity. Four Lego minifigures will also be on the flight in a nod to the longstanding relationship between NASA and Lego and as part of an effort to promote STEM education.
In addition to the scientific efforts of the Orion capsule, the ship will also carry over fifty kilograms of mementos, including a space time capsule, seeds, and an Amazon Alexa embedded in a device called Callisto, who in keeping with NASA’s Greek mythology inclinations, was Artemis’ hunting attendant.
In spite of this memento laden crewless Orion capsule, NASA claims that once it gets figuratively off the ground, its new Artemis program will, in contrast to the earlier Apollo missions, be less focused on ‘flags and footprints’ and more on science research and getting humanity ready for longer term habitats on the moon and ultimately Mars.
Notably, Israel isn’t the only country collaborating with the United States on its return to the moon. The Artemis program is a multinational effort of which Israeli is a recent member. Saudi Arabia just signed on as the 21st nation to the Artemis Accords during US President Joe Biden’s recent middle east trip. Canada is another collaborator on the Artemis project. The Canadian government will be providing a third iteration of its famous robotic Canadarm, as well as a moon rover for the project. A Canadian astronaut will also fill one of the four seats on the first crewed Artemis flight to the moon.
Given its interest in mankind’s return to the moon, Canada is keen on having its astronauts on their best behavior. As such, there was a recommendation to amend Canada’s criminal laws to specifically include the possibility of prosecution for misdemeanors committed on the moon by Canadians. Crimes committed on the International Space Station by Canadians already fall within the long-arm of the Canadian justice system.
While the US has not yet followed suit with similar legislation, US Vice President Kamala Harris recently announced an interest in revising other aspects of US space regulations so that they are more in-line with the current state of commercial space exploration. A follow-up tweet announced that this will be explored in greater detail next month, around the same time that the Artemis rocket will be sitting in Lunar orbit
However, expanding Canadian, or any other jurisdiction for that matter, onto the moon might come in conflict with what NASA administrator Bill Nelson claims is China’s goal of claiming the moon as its own: “We must be very concerned that China is landing on the moon and saying: It’s ours now and you stay out.” In their defense, China rejects that assertion.

Of course, China isn’t the only national player that might lay claim to some or all of the moon. The Artemis Accords to which Israel is a signatory, allow for national efforts to mine and extract valuable resources from the moon and other celestial bodies — a potentially, hugely profitable endeavor. In spite of non-appropriation and ‘province of all mankind’ language within the universally accepted Outer Space Treaty.
All these lunar land claims could create some interesting legal precedent. The last time NASA had a legal tussle with putative private property proprietors in space. they won against the pro se claimant on a technicality (Nemitz v. NASA, 126 Fed. Appx. 343 (2005). Hopefully with so many potential claimants and the possibility of a manned lunar base, the next time NASA is sued for landing on someone’s lunar claim, the outcome will be more interesting.

If last week’s solar eclipse piqued your interest in astronomy, the Royal Astronomical Society of Canada’s Windsor Chapter plans to show off some of the more dramatic photos and videos members took of the event.
They were stationed along the path of totality along the northern shore of Lake Erie and in the U.S.
“People did take some nice photos with their cellphones, but we have members who took photos and videos with their telescopes,” said member Tom Sobocan. “You’ll see some pretty impressive shots.”
About 100 members are in the local chapter, which meets every third Tuesday of every month.
Thursday’s meeting is at the Ojibway Nature Centre on Matchette Road. It starts at 7:30, and it’s open to the public. Seating is limited, so Sobocan recommends arriving early.
Astronomers are looking ahead to new wonders in the heavens. Right now, the Pons-Brooks Comet, another once-in-a-lifetime opportunity, is approaching Jupiter in the constellation of Aries.
“If you’re in a dark-sky location, you can see it with the naked eye, and from inside the city, you can see it with binoculars,” said Sobocan. “It may get a little bit brighter going towards the fall, but our members have already photographed it with their telescopes.”
It’s a periodic comet which appears in the night sky once every 71 years.
Sobocan said once-in-a-lifetime events, like last week’s eclipse, inspired many of its existing members, but he hopes some new ones will join the group.
“I hope it inspires them to look up at the sky a little bit more often and realize that everything’s in motion in the sky,” he said. “It’s not stationary.”

Giant, 82-foot lizard fish discovered on UK beach could be largest marine reptile ever found – Livescience.com
Scientists have unearthed the remains of a gigantic, 200 million-year-old sea monster that may be the largest marine reptile ever discovered.
The newfound creature is a member of a group called ichthyosaurs, which were among the dominant sea predators during the Mesozoic era (251.9 million to 66 million years ago). The newly described species lived during the end of the Triassic period (251.9 million to 201.4 million years ago).
Ichthyosaurs had already attained massive sizes by the early portion of the Mesozoic, but it was not until the late Triassic that the largest species emerged.
While the Mesozoic is known as the age of the dinosaurs, ichthyosaurs were not themselves dinosaurs. Instead, they evolved from another group of reptiles. Their evolutionary path closely mirrors that of whales, which evolved from terrestrial mammals that later returned to the sea. And like whales, they breathed air and gave birth to live young.
The newly discovered ichthyosaur species was unearthed in pieces between 2020 and 2022 at Blue Anchor, Somerset in the United Kingdom. The first chunk of the fossil was noticed atop a rock on the beach, indicating that a passerby had found it and set it there for others to examine, the researchers explained in the paper. The researchers published their findings April 17 in the journal PLOS One.
The reptile’s remains are made up of a series of 12 fragments from a surangular bone, which is found in the upper portion of the lower jaw. The researchers estimate the bone was 6.5 feet (2 meters) long and that the living animal was about 82 feet (25 m) long.
The researchers named the sea monster Ichthyotitan severnensis, meaning giant lizard fish of the Severn, after the Severn Estuary where it was found. The team believes it is not only a new species but an entirely new genus of ichthyosaur. More than 100 species are already known.

A number of rib fragments and a coprolite, or fossilized feces, were found in the area as well, but they were not definitively attributed to the same animal.
The sediments in which these specimens were found contained rocks that indicated earthquakes and tsunamis occurred during that time, which suggests that this species lived during a time of intense volcanic activity that may have led to a massive extinction event at the end of the Triassic according to the researchers.
A similar specimen was discovered in Lilstock, Somerset in 2016 and described in 2018. Both were found in what is known at the Westbury Mudstone Formation, within 6 miles (10 kilometers) of each other. This ichthyosaur was estimated to have been as much as 85 feet (26 m) long, although the authors of the latest study believe it was slightly smaller.
The previous contender for the largest marine reptile was another ichthyosaur, Shonisaurus sikanniensis, which was up to 69 feet (21 m) long. S. sikanniensis appeared 13 million years earlier than I. severnensis and was found in British Columbia, making it unlikely that the new discovery represents another specimen of the previously known species.
A similarly massive ichthyosaur called Himalayasaurus tibetensis, which may have reached lengths of 49 feet (15 m), was discovered in Tibet and described in 1972. It dates to the same period, meaning that it probably is not the same species as the new discovery either.
I. severnensis was likely among the last of the giant ichthyosaurs, the researchers claim. Ichthyosaurs persisted into the Cenomanian Age (100.5 million to 93.9 million years ago) of the late Cretaceous period (100.5 million to 66 million years ago). They were eventually supplanted by plesiosaurs — long-necked marine reptiles that went extinct at the end of the Cretaceous, alongside all non-avian dinosaurs.

The Canadian Space Agency also received a proposed $8.6 million for its lunar program
Nicole Mortillaro (new window) · CBC News
Canada’s space sector received a boost from the federal government in its budget, both in terms of money and vision.
The 2024 budget (new window) included a proposal for $8.6 million in 2024-25 to the Canadian Space Agency (CSA) for the Lunar Exploration Accelerator Program (new window) (LEAP), which invests in technologies for humanity’s return to the moon and beyond.
In addition to the funding, the federal government also announced the creation of a National Space Council, which will be a new whole-of-government approach to space exploration, technology development, and research.
For Space Canada (new window), an organization comprised of roughly 80 space sector companies including some of Canada’s largest, such as Magellan Aerospace (new window), Maritime Launch (new window) and MDA Space (new window), it was a welcome announcement.
We’ve been advocating for it since the inception of our organization, and we were really very happy, and we applaud the federal government’s commitment announced in the budget,
said Brian Gallant, CEO of Space Canada.
Gallant said that investment in space is an investment in Canada.
Two-thirds of space sector jobs are STEM jobs. These are good paying solid jobs for Canadians. And on top of that, we have approximately $2.8 billion that is injected into the Canadian economy because of the space sector,
he said.
The U.S. formed its National Space Council in 1989, but it was disbanded in 1992 and reestablished in 2017.
In the 2023 budget (new window), the government announced proposed spending of $1.2 billion over 13 years, that was to begin in 2024-25, to the CSA’s contribution of a lunar utility (new window) vehicle that would assist astronauts on the moon. The as–yet–developed vehicle could help astronauts move cargo from landing sites to habitats, perform science investigations or support them during spacewalks on the surface of the moon.
It also proposed to invest $150 million over five years for the LEAP program.
MDA Space, the company behind Canadarm, was also pleased with the announcement.
Canada has an enviable global competitive advantage in space and the creation of a National Space Council is critical to Canada maintaining that leadership position,
CEO Mike Greenley said in an email to CBC News.
Space is now a rapidly growing, highly strategic and competitive domain, and there is a real and urgent need to recognize its importance to the lives of Canadians and to our economy and national security.
The next project for MDA is Canadarm3, which will be part of Lunar Gateway, a international space station that will orbit the moon. It will serve as a sort of jumping-off point for astronauts heading to the moon and eventually beyond.
The Lunar Gateway is a great opportunity for Canada and for MDA Space to not only provide the next generation of Canadarm robotics but to clearly plant our flag as a core national and industry participant in the Artemis era,
Greenley said.
Lunar Gateway is set to begin construction no earlier than 2025 (new window), according to NASA.
