Elon Musk’s SpaceX is gearing up to send a crew of astronauts to the International Space Station for the fourth time.
The mission, dubbed Crew-3, will carry NASA astronauts Raja Chari, Tom Marshburn and Kayla Barron, along with European Space Agency astronaut Matthias Maurer, to the ISS for a six-month stay in orbit.
The spaceflight, moved to Wednesday from Sunday because of weather, will be the first for three of the four crew members.
The veteran on the mission is Marshburn. The doctor and former NASA flight surgeon, making his third trip to space, said this research could one day answer bigger questions about human existence.
“It’s every one of us who has looked into the night sky and wondered, ‘How does the universe work, and how did life come to our planet Earth?'” Marshburn told ABC News.
Barron, an astronaut who has experience on submarines, said her time in Navy has helped prepare her for this moment — and that she made a playlist for the ride out.
“There are some strong millennial favorites on my playlist and throwbacks to the ’90s,” she joked.
They will launch aboard SpaceX’s Crew Dragon spacecraft and Falcon 9 rocket.
The crew is scheduled to spend 22 hours in the capsule before docking with the ISS. The team decided to call the new capsule “Endurance” — a tribute to the human spirit and a historic sailing vessel used by Antarctic explorer Ernest Shackleton.
SpaceX launched two NASA astronauts to the ISS successfully for the first time in June 2020, which cleared them to continue conducting flights with their rocket and Crew Dragon. It was the first crewed launch to depart from American soil in nearly a decade.
Last month SpaceX’s Inspiration4 mission made history as civilians traveled the greatest distance away from Earth — 367 miles — even farther than the International Space Station.
But on that flight they discovered an issue with the toilet inside the Crew Dragon that almost hampered the Crew-3 launch. A tube became unglued and spilled urine onto fans beneath the floor.
“It had no impact on Inspiration4 at all,” William Gerstenmair, SpaceX’s vice president, said during a press conference. “We didn’t really even notice it, the crew didn’t notice it, until we got the vehicle back and we looked under the floor and we saw the fact that there was contamination.”
Engineers eventually fixed the problem.
SpaceX is contracted to launch up to six crewed flights for NASA, with two more scheduled for 2022.
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.
