NASA astronauts have donned a lot of different spacesuits over the decades.Dragan Radovanovic/Business Insider
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.
Sokol Launch and Entry Suit (present)

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.
NAIROBI, Kenya (AP) — The body of Ugandan Olympic athlete Rebecca Cheptegei — who died after being set on fire by her partner in Kenya — was received Friday by family and anti-femicide crusaders, ahead of her burial a day later.
Cheptegei’s family met with dozens of activists Friday who had marched to the Moi Teaching and Referral Hospital’s morgue in the western city of Eldoret while chanting anti-femicide slogans.
She is the fourth female athlete to have been killed by her partner in Kenya in yet another case of gender-based violence in recent years.
Viola Cheptoo, the founder of Tirop Angels – an organization that was formed in honor of athlete Agnes Tirop, who was stabbed to death in 2021, said stakeholders need to ensure this is the last death of an athlete due to gender-based violence.
“We are here to say that enough is enough, we are tired of burying our sisters due to GBV,” she said.
It was a somber mood at the morgue as athletes and family members viewed Cheptegei’s body which sustained 80% of burns after she was doused with gasoline by her partner Dickson Ndiema. Ndiema sustained 30% burns on his body and later succumbed.
Ndiema and Cheptegei were said to have quarreled over a piece of land that the athlete bought in Kenya, according to a report filed by the local chief.
Cheptegei competed in the women’s marathon at the Paris Olympics less than a month before the attack. She finished in 44th place.
Cheptegei’s father, Joseph, said that the body will make a brief stop at their home in the Endebess area before proceeding to Bukwo in eastern Uganda for a night vigil and burial on Saturday.
“We are in the final part of giving my daughter the last respect,” a visibly distraught Joseph said.
He told reporters last week that Ndiema was stalking and threatening Cheptegei and the family had informed police.
Four in 10 women or an estimated 41% of dating or married Kenyan women have experienced physical or sexual violence perpetrated by their current or most recent partner, according to the Kenya Demographic and Health Survey 2022.
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.”
VICTORIA – The British Columbia government is partnering with a bear welfare group to reduce the number of bears being euthanized in the province.
Nicholas Scapillati, executive director of Grizzly Bear Foundation, said Monday that it comes after months-long discussions with the province on how to protect bears, with the goal to give the animals a “better and second chance at life in the wild.”
Scapillati said what’s exciting about the project is that the government is open to working with outside experts and the public.
“So, they’ll be working through Indigenous knowledge and scientific understanding, bringing in the latest techniques and training expertise from leading experts,” he said in an interview.
B.C. government data show conservation officers destroyed 603 black bears and 23 grizzly bears in 2023, while 154 black bears were killed by officers in the first six months of this year.
Scapillati said the group will publish a report with recommendations by next spring, while an independent oversight committee will be set up to review all bear encounters with conservation officers to provide advice to the government.
Environment Minister George Heyman said in a statement that they are looking for new ways to ensure conservation officers “have the trust of the communities they serve,” and the panel will make recommendations to enhance officer training and improve policies.
Lesley Fox, with the wildlife protection group The Fur-Bearers, said they’ve been calling for such a committee for decades.
“This move demonstrates the government is listening,” said Fox. “I suspect, because of the impending election, their listening skills are potentially a little sharper than they normally are.”
Fox said the partnership came from “a place of long frustration” as provincial conservation officers kill more than 500 black bears every year on average, and the public is “no longer tolerating this kind of approach.”
“I think that the conservation officer service and the B.C. government are aware they need to change, and certainly the public has been asking for it,” said Fox.
Fox said there’s a lot of optimism about the new partnership, but, as with any government, there will likely be a lot of red tape to get through.
“I think speed is going to be important, whether or not the committee has the ability to make change and make change relatively quickly without having to study an issue to death, ” said Fox.
This report by The Canadian Press was first published Sept. 9, 2024.
