Astronauts can't return to moon by 2024 because spacesuits aren't ready, NASA watchdog – CTV News
NASA’s goal of returning American astronauts to the moon by 2024 isn’t feasible because of significant delays in developing spacesuits, NASA Inspector General Paul K. Martin said in a new report.
Even though NASA will have spent more than a billion dollars on the next-generation spacesuits, Martin concluded that the “suits would not be ready for flight until April 2025 at the earliest” and are “years away from completion.”
The report attributes the delays to funding shortfalls, COVID-19 impacts and technical challenges. Currently, there are 27 different companies supplying various components for the suits. SpaceX’s Elon Musk said on Twitter that the report makes it seem “like too many cooks in the kitchen,” adding that “SpaceX could do it if need be.”
SpaceX won a US$2.9 billion contract from NASA in April to develop the lunar lander for the Artemis program. But the awarding of that contract was delayed due to a protest from two competitors, Blue Origin and Dynetics. The inspector general said those protests, combined with delays to NASA’s Space Launch System and Orion Capsule, also contributed to NASA’s inability to meet its goal of a 2024 landing. The issues have resulted in approximately 20 months of delay to the flight suit delivery schedule, according to the report.
Current NASA Administrator Bill Nelson addressed the 2024 readiness question during a recent interview with CNN’s Rachel Crane.
“I’m soberly realistic. The goal is 2024, but space is hard. And we know when you are pushing the edge of the envelope, often there are delays. There’s a No. 1 factor and that’s safety, and it’s involving humans. There might be a delay, but the goal is late 2024.”
Former NASA Deputy Administrator Lori Garver has previously criticized the 2024 time line and compared the Artemis program to the parable of the emperor with no clothes.
In response to the release of the report, Garver told CNN, “Unfortunately, I don’t think the emperor has many clothes left on under the spacesuit either.”
An audit was carried out between August 2020 and July 2021 to examine the development of NASA’s next-generation spacesuits required for the International Space Station and Artemis missions that will return humans to the moon later this decade.
The development of new spacesuits is critical for “returning humans to the Moon, continuing safe operations on the International Space Station, and exploring Mars and other deep space locations,” according to the report.
These Extravehicular Mobility Units, or EMUs, include the spacesuit and hardware that astronauts use to connect to the ISS and other spacecraft.
“Currently, astronauts use EMUs designed 45 years ago for the Space Shuttle Program and rely on these refurbished and partially redesigned spacesuits for extravehicular activities on the ISS,” according to the report.
The development of new spacesuit technology has been ongoing at NASA for the last 14 years. Five years ago, work began on the Exploration Extravehicular Mobility Units, or xEMU project. Two flight-ready xEMUs, as well as a test suit and a demo suit for the ISS, are also needed ahead of this historic lunar landing.
The report noted that the failure to complete the suits ahead of the November 2024 planned mission, known as Artemis III, isn’t the only factor impacting the schedule.
Recommendations to get back on track
To make sure the xEMUs are completed, the report made four recommendations including adjusting the schedule to reduce development risks and creating a master schedule that brings hardware and training needs together.
The document also suggests “ensuring technical requirements for the next-generation suits are solidified before selecting the acquisition strategy to procure suits for the ISS and Artemis programs” and making sure that strategy meets the needs of both programs.
“The lunar landing relies on the HLS Program, which is early in the design phase, but has specific requirements for the technical capability, functionality, and overall size of the suits,” according to the report. “However, the suits are also needed as soon as possible by the ISS Program to replace aging suits that have exceeded their design life by more than 25 years, necessitating costly maintenance to ensure astronaut safety. Thus far, NASA has struggled to align these schedules with mission needs.”
After receiving a draft of the report, NASA management agreed with the recommendations and has plans to address them.
“NASA intends to perform a demonstration prior to the first Artemis crewed mission” by June 2022, according a letter from Kathryn Lueders, NASA’s Associate Administrator of the Human Exploration and Operations Mission Directorate, that was included in the report.
The agency released a statement on Tuesday addressing the report.
“Sending the first woman and first person of color to the lunar surface and establishing a long-term presence at the Moon under Artemis is a priority for NASA. The agency is evaluating the current budget and schedule for Artemis missions and will provide an update later this year,” according to the statement.
The goal to land the first woman and the next man on the moon was established by the Trump administration originally for 2028, then moved up to November 2024. In addition to adopting the goal, the Biden administration added seeking to land the first person of color on the moon to the program’s goal.

A coronal mass ejection, an explosion of magnetic fields and plasma from the sun’s atmosphere, hit Earth early Friday with more force than initially forecast. These events can disrupt Earth’s magnetic field causing auroral displays, as well as disrupting satellites, communication and electric grids.

The US Space Weather Prediction Center had originally expected a G2 level storm Friday on its five-step scale, the event measured in at G4, one of the strongest triggered on Earth since 2017.
The impacts from the coronal mass ejection have trailed off, but energy coming from what scientists call a “coronal hole” will continue at least through Saturday and that could mean the aurora could be seen by viewers across Europe, Asia and North America through Sunday, the UK Met Office said on its website.
There are currently eight sunspot clusters visible on the side of the sun facing Earth, however another coronal mass ejection blasting toward us isn’t forecast, the UK Met Office said.

An asteroid dubbed “city killer” for its size will pass harmlessly between the moon and the Earth Saturday evening.
The asteroid 2023 DZ2 will pass at a distance of over 100,000 miles, less than half the distance between the Earth and the moon. It’s about 160 feet long — about the size of an airliner. An asteroid that size could cause significant damage if it hit a populated area, hence its nickname.
“While close approaches are a regular occurrence, one by an asteroid of this size (140-310 ft) happens only about once per decade, providing a unique opportunity for science,” NASA Asteroid Watch tweeted.
Astronomers from the International Asteroid Warning Network, established about 10 years ago to coordinate international responses to potential near-Earth object impact threats, will be monitoring and learning from this asteroid.
NASA Asteroid Watch called the opportunity “good practice” in case “a potential asteroid threat were ever discovered.”
Near-Earth objects are asteroids or comets that pass close to the Earth’s orbit, and they generally come from objects that are affected by other planets’ gravity, moving them into orbits that push them close to Earth, according to the United Nations Office for Outer Space Affairs.
The European Space Agency maintains a risk list of 1,460 objects, which catalogs every object with a non-zero chance of hitting Earth over the next 100 years. Asteroid 2023 DZ2, which is in orbit around the sun, is not on the risk list.

On Saturday, the 2023DZ2 will come within a third of the distance from the Earth to the Moon.
A large asteroid will safely zoom between Earth and the Moon on Saturday, a once-in-a-decade event that will be used as a training exercise for planetary defence efforts, according to the European Space Agency.
The asteroid, named 2023 DZ2, is estimated to be 40 to 70 metres (130 to 230 feet) wide, roughly the size of the Parthenon, and big enough to wipe out a large city if it hit our planet.
At 19:49 GMT on Saturday, it will come within a third of the distance from the Earth to the Moon, said Richard Moissl, the head of the ESA’s planetary defence office.
Though that is “very close”, there is nothing to worry about, he told AFP news agency.
Small asteroids fly past every day, but one of this size coming so close to Earth only happens about once every 10 years, he added.
The asteroid will pass 175,000km (109,000 miles) from Earth at a speed of 28,000 kilometres per hour (17,400 miles per hour). The Moon is roughly 385,000km (239,228 miles) away.
An observatory in La Palma, one of Spain’s Canary Islands, first spotted the asteroid on February 27.
Last week, the United Nations-endorsed International Asteroid Warning Network decided it would take advantage of the close look, carrying out a “rapid characterisation” of 2023 DZ2, Moissl said. That means astronomers around the world will analyse the asteroid with a range of instruments such as spectrometers and radars.
The goal is to find out just how much we can learn about such an asteroid in only a week, Moissl said. It will also serve as training for how the network “would react to a threat” possibly heading our way in the future, he added.
The asteroid will again swing past Earth in 2026, but poses no threat of impact for at least the next 100 years – which is how far out its trajectory has been calculated.
