Here’s every key spacesuit NASA astronauts have worn since the 1960s — and the new moon suit it just unveiled

  • NASA unveiled the suit astronauts will wear during the 2025 Artemis III moon mission.
  • The new Extravehicular Mobility Unit spacesuit was developed by private company Axiom Space.
  • NASA gave astronauts their first operational spacesuits in the early 1960s.

Space may be the final frontier, but it’s wildly inaccessible and downright deadly to any plucky human without a great spacesuit.

Astronauts are scheduled to return to the moon for the first time in 50 years in 2025 with NASA’s Artemis III mission. The space agency just unveiled a new fit for the occasion, developed by private company Axiom Space.

NASA hired Axiom to build its latest spacesuits in June 2022, after it spent years and millions trying to develop its own. In August 2021, the agency reported that despite spending $420 million since 2017, its own suits wouldn’t be ready for space before April 2025 “at the earliest.”

Axiom’s new Extravehicular Mobility Unit leverages NASA’s own exploration version, introduced in 2019.

But the very first operational spacesuits were introduced in the early 1960s to protect high-flying astronauts as they risk their lives in the name of space exploration.

From the silvery suits of the Mercury program to Elon Musk’s sleek Crew Dragon suits, here’s how astronauts’ spacesuits have evolved over six decades.

Mercury Suit (1961-1963)

Project Mercury marked the first time US citizens ventured into orbit around Earth.

To protect the first astronauts from sudden pressure loss, NASA modified high-altitude jet-aircraft pressure suits from the US Navy. Each space suit had a layer of neoprene-coated nylon on the inside and aluminized nylon on the outside (to keep the suit’s inner temperature as stable as possible).

Six astronauts flew into space wearing the suit before NASA retired it from service.

Gemini Suit (1965-1966)

Gemini was NASA’s second space program — and one with more ambitious goals. The Gemini capsule carried a two-astronaut crew into space, and had one (uncomfortable) mission that lasted two weeks.

The David Clark Company designed Gemini suits to be flexible when pressurized, and took extra steps to make them more comfortable than Mercury suits. For example, they could be connected to a portable air conditioner to keep the astronauts cool until they could hook up to the spacecraft’s lines. These suits weighed 16-34 pounds.

Gemini Spacewalk Suit (1965-1966)

One type of Gemini suit, called G4C, was designed with NASA’s first spacewalks in mind. Astronauts would open the hatch during these ventures and leave the safety of their vehicle to work in the vacuum of space.

To withstand the harsh space environment, the suit connected the astronauts to the spacecraft via a hose, which supplied them with oxygen. In case there was a problem, though, some variants of the suit provided up to 30 minutes of backup life support. The heaviest variant weighed about 34 pounds.

Apollo Spacewalk Suit (1967-1975)

The Apollo program brought astronauts to the moon, and it was no walk in the park. The astronauts needed more protection than either the Gemini or Mercury suits could offer.

The first people to walk the moon required a shield against fine regolith (dust as sharp as glass); protection from wild temperature swings from sun to shade; the flexibility to install gear and pick up moon rocks; and the ability to last for hours away from a spacecraft.

The suit came with a dozen layers of fabric, thick boots, and a robust life-support system. Each weighed more than 180 pounds on Earth, but just one-sixth as much in the moon’s weaker gravity field.

First Space Shuttle Flight Suit (1981)

A mission called STS-1 — short for Space Transportation System-1 — was the first orbital spaceflight of NASA’s space shuttle program.

Columbia, the first 100-ton orbiter, carried a two-astronaut crew into space and orbited Earth 37 times before reentering the atmosphere and gliding back to a runway. Astronauts weren’t venturing outside, so they only wore an emergency ejection escape suit, which (like the Mercury suit) was a modified version of a US Air Force high-altitude pressure suit.

Extravehicular Mobility Unit (1979-present)

Astronauts of the space-shuttle era would work regularly in space to maintain satellites as well as construct and maintain the International Space Station (ISS).

They needed a workhorse spacewalk suit for such tasks, so NASA created the Extravehicular Mobility Unit. This 14-layer pressurized suit could withstand the harsh void of space and keep astronauts alive for more than eight hours. Fully loaded with gear and supplies, it could weigh nearly 320 pounds on Earth.

NASA also tested a jetpack-like device for the EMU, called a Manned Maneuvering Unit, that allowed astronauts to fly around free and untethered. People on board the ISS today use an advanced version of EMUs to maintain the space station.

Space Shuttle Flight Suit (1988-2011)

The suit that astronauts wore during the Space Shuttle program is sometimes called a “pumpkin suit” for its bright orange color. The suit is equipped with gloves on disconnecting lock rings on the wrist, liquid cooling, improved ventilation, and extra layers of insulation.

The sharp, blue-lined spacesuit you see many astronauts wearing today is actually a Russian suit called the Sokol or “Falcon” spacesuit.

The 22-pound suit is pretty similar to the space shuttle flight suit, though it’s used to protect people who fly inside Russia’s Soyuz spacecraft.

SpaceX Crew Dragon Flight Suit (2020 – present)

The sleek white spacesuits were designed by Elon Musk’s company SpaceX. Musk unveiled them during a press conference in 2017, and NASA astronauts Bob Nehnken and Doug Hurley first used them when they flew into space in a SpaceX capsule in May 2020 with the Crew Dragon mission.

Jose Fernandez, a Hollywood costume designer that has worked on movies like X-Men: Dark Phoenix, Aquaman, and Thor: Ragnarok, came up with the design. While elegant and futuristic, the suits were only made for the Crew Dragon capsule and are not suitable for taking a space walk.

Crew Dragons are used to transport NASA astronauts to and from the International Space Station, as well as for commercial flights.

Boeing CST-100 Starliner Flight Suit (2022 – present)

First expected in 2019, Boeing unveiled its bright blue Starliner flight suit in June 2022. It is designed to be used on the CST-100 Starliner capsules, which are expected to take their first crew to space imminently.

The suit includes a helmet attached with a thick, air-tight zipper (no heavy or bulky neck ring required).

The Axiom Extravehicular Mobility Unit suits, or AxEMUs, will be delivered to NASA by the summer. The dark gray and orange version unveiled in March 2023 is a prototype, and the final version will be white.

Astronauts have to wear white when on the moon to reflect heat and protect themselves from high temperatures.

Here’s how Helene and other storms dumped a whopping 40 trillion gallons of rain on the South

Published

 on

 

More than 40 trillion gallons of rain drenched the Southeast United States in the last week from Hurricane Helene and a run-of-the-mill rainstorm that sloshed in ahead of it — an unheard of amount of water that has stunned experts.

That’s enough to fill the Dallas Cowboys’ stadium 51,000 times, or Lake Tahoe just once. If it was concentrated just on the state of North Carolina that much water would be 3.5 feet deep (more than 1 meter). It’s enough to fill more than 60 million Olympic-size swimming pools.

“That’s an astronomical amount of precipitation,” said Ed Clark, head of the National Oceanic and Atmospheric Administration’s National Water Center in Tuscaloosa, Alabama. “I have not seen something in my 25 years of working at the weather service that is this geographically large of an extent and the sheer volume of water that fell from the sky.”

The flood damage from the rain is apocalyptic, meteorologists said. More than 100 people are dead, according to officials.

Private meteorologist Ryan Maue, a former NOAA chief scientist, calculated the amount of rain, using precipitation measurements made in 2.5-mile-by-2.5 mile grids as measured by satellites and ground observations. He came up with 40 trillion gallons through Sunday for the eastern United States, with 20 trillion gallons of that hitting just Georgia, Tennessee, the Carolinas and Florida from Hurricane Helene.

Clark did the calculations independently and said the 40 trillion gallon figure (151 trillion liters) is about right and, if anything, conservative. Maue said maybe 1 to 2 trillion more gallons of rain had fallen, much if it in Virginia, since his calculations.

Clark, who spends much of his work on issues of shrinking western water supplies, said to put the amount of rain in perspective, it’s more than twice the combined amount of water stored by two key Colorado River basin reservoirs: Lake Powell and Lake Mead.

Several meteorologists said this was a combination of two, maybe three storm systems. Before Helene struck, rain had fallen heavily for days because a low pressure system had “cut off” from the jet stream — which moves weather systems along west to east — and stalled over the Southeast. That funneled plenty of warm water from the Gulf of Mexico. And a storm that fell just short of named status parked along North Carolina’s Atlantic coast, dumping as much as 20 inches of rain, said North Carolina state climatologist Kathie Dello.

Then add Helene, one of the largest storms in the last couple decades and one that held plenty of rain because it was young and moved fast before it hit the Appalachians, said University of Albany hurricane expert Kristen Corbosiero.

“It was not just a perfect storm, but it was a combination of multiple storms that that led to the enormous amount of rain,” Maue said. “That collected at high elevation, we’re talking 3,000 to 6000 feet. And when you drop trillions of gallons on a mountain, that has to go down.”

The fact that these storms hit the mountains made everything worse, and not just because of runoff. The interaction between the mountains and the storm systems wrings more moisture out of the air, Clark, Maue and Corbosiero said.

North Carolina weather officials said their top measurement total was 31.33 inches in the tiny town of Busick. Mount Mitchell also got more than 2 feet of rainfall.

Before 2017’s Hurricane Harvey, “I said to our colleagues, you know, I never thought in my career that we would measure rainfall in feet,” Clark said. “And after Harvey, Florence, the more isolated events in eastern Kentucky, portions of South Dakota. We’re seeing events year in and year out where we are measuring rainfall in feet.”

Storms are getting wetter as the climate change s, said Corbosiero and Dello. A basic law of physics says the air holds nearly 4% more moisture for every degree Fahrenheit warmer (7% for every degree Celsius) and the world has warmed more than 2 degrees (1.2 degrees Celsius) since pre-industrial times.

Corbosiero said meteorologists are vigorously debating how much of Helene is due to worsening climate change and how much is random.

For Dello, the “fingerprints of climate change” were clear.

“We’ve seen tropical storm impacts in western North Carolina. But these storms are wetter and these storms are warmer. And there would have been a time when a tropical storm would have been heading toward North Carolina and would have caused some rain and some damage, but not apocalyptic destruction. ”

‘Big Sam’: Paleontologists unearth giant skull of Pachyrhinosaurus in Alberta

Published

 on

 

It’s a dinosaur that roamed Alberta’s badlands more than 70 million years ago, sporting a big, bumpy, bony head the size of a baby elephant.

On Wednesday, paleontologists near Grande Prairie pulled its 272-kilogram skull from the ground.

They call it “Big Sam.”

The adult Pachyrhinosaurus is the second plant-eating dinosaur to be unearthed from a dense bonebed belonging to a herd that died together on the edge of a valley that now sits 450 kilometres northwest of Edmonton.

It didn’t die alone.

“We have hundreds of juvenile bones in the bonebed, so we know that there are many babies and some adults among all of the big adults,” Emily Bamforth, a paleontologist with the nearby Philip J. Currie Dinosaur Museum, said in an interview on the way to the dig site.

She described the horned Pachyrhinosaurus as “the smaller, older cousin of the triceratops.”

“This species of dinosaur is endemic to the Grand Prairie area, so it’s found here and nowhere else in the world. They are … kind of about the size of an Indian elephant and a rhino,” she added.

The head alone, she said, is about the size of a baby elephant.

The discovery was a long time coming.

The bonebed was first discovered by a high school teacher out for a walk about 50 years ago. It took the teacher a decade to get anyone from southern Alberta to come to take a look.

“At the time, sort of in the ’70s and ’80s, paleontology in northern Alberta was virtually unknown,” said Bamforth.

When paleontogists eventually got to the site, Bamforth said, they learned “it’s actually one of the densest dinosaur bonebeds in North America.”

“It contains about 100 to 300 bones per square metre,” she said.

Paleontologists have been at the site sporadically ever since, combing through bones belonging to turtles, dinosaurs and lizards. Sixteen years ago, they discovered a large skull of an approximately 30-year-old Pachyrhinosaurus, which is now at the museum.

About a year ago, they found the second adult: Big Sam.

Bamforth said both dinosaurs are believed to have been the elders in the herd.

“Their distinguishing feature is that, instead of having a horn on their nose like a triceratops, they had this big, bony bump called a boss. And they have big, bony bumps over their eyes as well,” she said.

“It makes them look a little strange. It’s the one dinosaur that if you find it, it’s the only possible thing it can be.”

The genders of the two adults are unknown.

Bamforth said the extraction was difficult because Big Sam was intertwined in a cluster of about 300 other bones.

The skull was found upside down, “as if the animal was lying on its back,” but was well preserved, she said.

She said the excavation process involved putting plaster on the skull and wooden planks around if for stability. From there, it was lifted out — very carefully — with a crane, and was to be shipped on a trolley to the museum for study.

“I have extracted skulls in the past. This is probably the biggest one I’ve ever done though,” said Bamforth.

“It’s pretty exciting.”

The ancient jar smashed by a 4-year-old is back on display at an Israeli museum after repair

Published

 on

 

TEL AVIV, Israel (AP) — A rare Bronze-Era jar accidentally smashed by a 4-year-old visiting a museum was back on display Wednesday after restoration experts were able to carefully piece the artifact back together.

Last month, a family from northern Israel was visiting the museum when their youngest son tipped over the jar, which smashed into pieces.

Alex Geller, the boy’s father, said his son — the youngest of three — is exceptionally curious, and that the moment he heard the crash, “please let that not be my child” was the first thought that raced through his head.

The jar has been on display at the Hecht Museum in Haifa for 35 years. It was one of the only containers of its size and from that period still complete when it was discovered.

The Bronze Age jar is one of many artifacts exhibited out in the open, part of the Hecht Museum’s vision of letting visitors explore history without glass barriers, said Inbal Rivlin, the director of the museum, which is associated with Haifa University in northern Israel.

It was likely used to hold wine or oil, and dates back to between 2200 and 1500 B.C.

Rivlin and the museum decided to turn the moment, which captured international attention, into a teaching moment, inviting the Geller family back for a special visit and hands-on activity to illustrate the restoration process.

Rivlin added that the incident provided a welcome distraction from the ongoing war in Gaza. “Well, he’s just a kid. So I think that somehow it touches the heart of the people in Israel and around the world,“ said Rivlin.

Roee Shafir, a restoration expert at the museum, said the repairs would be fairly simple, as the pieces were from a single, complete jar. Archaeologists often face the more daunting task of sifting through piles of shards from multiple objects and trying to piece them together.

Experts used 3D technology, hi-resolution videos, and special glue to painstakingly reconstruct the large jar.

Less than two weeks after it broke, the jar went back on display at the museum. The gluing process left small hairline cracks, and a few pieces are missing, but the jar’s impressive size remains.

The only noticeable difference in the exhibit was a new sign reading “please don’t touch.”
