Israeli private satellite with state-of-the-art camera launched into orbit

An Israeli commercial observation satellite was successfully launched into orbit by a SpaceX Falcon 9 rocket from the Vandenberg Space Force Base in California on Friday.

The EROS C-3 satellite, developed by Israel Aerospace Industries (IAI) and owned and operated by private Israeli intelligence firm ImageSat International, is capable of producing “very high-resolution images” and will be used for “governmental and business applications,” IAI said in a statement.

The advanced “multispectral” space camera was produced by Israel’s Elbit systems, and enables the satellite to take color photos.

“After launch, the satellite entered its planned orbit around the Earth and
began transmitting data to the ground station,” IAI said in its statement.

“Engineers at Israel Aerospace Industries have begun a series of preplanned calibrations and tests to validate the satellite’s performance, and complete the preplan test prior to full operation soon,” it added.

According to SpaceX, the reusable first stage segment of its Falcon 9 rocket successfully touched back down on a launch pad eight minutes after lift-off.

It was the final launch of the company, owned by billionaire Elon Musk, for 2022.

IAI’s board of directors chairman Amir Peretz hailed the launch as “further proof of the company’s technological leadership as a true path-breaker in space as in other arenas.

“The outputs from the satellite launched today, and the important findings that it will transmit to the ground station, will assist IAI in continuing to improve its advanced capabilities in these areas.”

IAI president and CEO Boaz Levy said: “Today’s launch of the EROS-C3 satellite is a further expression of the advanced technological capabilities of Israel Aerospace Industries, the space house of the State of Israel.”

IAI develops and manufactures advanced systems for air, space, sea, land, cyber and homeland security. Since 1953, the company has provided technology solutions to government and commercial customers worldwide, including satellites, missiles, weapon systems and munitions, unmanned and robotic systems, and radar.

ImageSat International’s CEO Noam Segal hailed the launch, saying it was a “significant milestone” for the company and “will enable us to accelerate the company’s growth.”

Israel’s Defense Ministry previously outsourced ISI’s imagery in the early 2000s, after the failed launch of the military Ofek-4 satellite.

The EROS satellites are widely believed to have been built using commercialized technology from the Ofek series of military reconnaissance satellites.

The Israeli military currently operates the Ofek-16 spy satellite, launched in 2020. It has a planned five-year mission duration.

NASA wants ideas to boost the Hubble Space Telescope into a higher orbit with private spaceships

NASA is looking deeper into the possibility of using a private spacecraft to lift the Hubble Space Telescope to new heights, giving the influential space observatory a new lease on life. 

On Dec. 22, the space agency issued a Request for Information regarding a non-exclusive SpaceX study earlier this year that suggested how the Hubble Space Telescope could be “reboosted” into a higher orbit.

NASA’s request for information, which you can read here, comes as it continues to consider the space telescope’s future and will remain open until Jan. 24, 2023.

Related: The  best Hubble Space Telescope images of all time

Since the start of Hubble’s operations in 1990, the orbit of the space telescope 335 miles (540 kilometers) above Earth has been decaying. Reboosting it to an orbit that is both higher and more stable could add years to Hubble’s operating lifetime delaying the point at which NASA must deorbit or dispose of the telescope.

During its five space shuttle missions to the service Hubble, NASA used the shuttle to reboost the telescope. The last shuttle servicing mission to Hubble was in 2009. NASA retired its shuttle fleet in 2011.

The idea to raise Hubble to a higher orbit using a Dragon spacecraft at no cost to the government was first developed between SpaceX and Polaris Program, a private program of space missions using SpaceX’s Dragon and Starship vehicles funded by billionaire Jared Isaacman. The unfunded agreement between SpaceX and NASA to study the feasibility of reboosting Hubble was then signed in September 2022.

The SpaceX study was designed to help NASA, which currently has no plans to operate or fund a new Hubble servicing mission, determine the commercial possibility of such a mission. The SpaceX study also aimed to lay out the technical challenges of such a servicing endeavor. 

The fact the study is non-exclusive means that other companies are free to propose their own Hubble servicing studies based on the use of different rockets or spacecraft. 

These studies will collect data from Hubble itself and from SpaceX’s Dragon spacecraft to assess the possibility of safely rendezvousing and docking with the space telescope before shunting it to a higher stable orbit. The studies are expected to take around 6 months to complete. 

“This study is an exciting example of the innovative approaches NASA is exploring through private-public partnerships,” associate administrator for the Science Mission Directorate at NASA Headquarters in Washington, Thomas Zurbuchen, said in a statement. (opens in new tab) “As our fleet grows, we want to explore a wide range of opportunities to support the most robust, superlative science missions possible.”

The operation to reboost Hubble would demonstrate how older satellites and spacecraft could be given extended operating lives, especially those in near-Earth orbits like the space telescope. 

“SpaceX and the Polaris Program want to expand the boundaries of current technology and explore how commercial partnerships can creatively solve challenging complex problems,” said Jessica Jensen, vice president of Customer Operations & Integration at SpaceX. “Missions such as servicing Hubble would help us expand space capabilities to ultimately help all of us achieve our goals of becoming a space-faring, multiplanetary civilization.”

South Korea’s 1st moon probe Danuri begins to enter lunar orbit

Danuri, South Korea’s first deep-space exploration mission, is finally arriving at the moon after a four-month voyage. 

The Danuri spacecraft was expected to begin entering lunar orbit at on Friday (Dec. 17) at 2:45 p.m. EST (1945 GMT, 2:45 a.m. Dec. 17 in South Korea), according to a statement (opens in new tab) from the Korea Aerospace Research Institute (KARI). The maneuver, the first of five planned engine burns through Dec. 28 to refine Danuri’s orbit around the moon, will clear the way for the probe to get started on its lunar science objectives.

Danuri, also known as the Korea Pathfinder Lunar Orbiter (KPLO), began its long and circuitous journey to the moon on Aug. 4, launching on a SpaceX Falcon 9 rocket from Florida’s Cape Canaveral Space Force Station. The moon probe has traveled over 3.3 million miles (5.4 million kilometers) on its journey so far, KARI officials have said.

Related: Every mission to the moon (reference)

The successful launch put Danuri into a ballistic lunar transfer orbit, which took the probe on a 134-day-long, looping, fuel-efficient voyage through Earth-moon space. It finally entered a polar lunar orbit with a target average altitude of 60 miles (100 kilometers) above the lunar surface. 

The 1,495-pound (678 kilograms) KPLO is South Korea’s first exploration mission to go beyond Earth orbit. That $180 million mission is ambitious; Danuri packs six separate science payloads designed to gather data for a range of science objectives. Five of those instruments — a terrain imager, a Wide-Angle Polarimetric Camera, magnetometer, gamma-ray spectrometer and a new networking technology test payload — were developed by Korean universities and research organizations. 

NASA also has a presence on board in the form of the sixth payload: a highly sensitive camera named ShadowCam that’s designed to scope out permanently shadowed regions at the lunar poles for hints of water-ice deposits. Data from the instrument could be helpful for NASA’s Artemis program, which aims to create a sustainable human presence on the moon.

After its first maneuver to enter orbit, Danuri is expected to follow it up with four more during moon approaches on Dec. 21, Dec. 23, Dec. 26 and Dec. 28 before settling into a final orbit on Dec. 29, KARI wrote in a statement (opens in new tab). All of those dates are in local time for South Korea.

KPLO is part of growing international interest in and activity at the moon. For example, Danuri reached the moon a month after the arrival of NASA’s CAPSTONE cubesat. The agency’s Artemis 1 mission successfully launched to lunar orbit and saw the Orion spacecraft return to Earth during the time Danuri was en route to the moon.

Danuri also marks the first step toward even grander lunar ambitions for South Korea, which also envisions a robotic moon landing around 2032 (opens in new tab) and a mission to Mars in 2045.

SpaceX sends 2 telecom satellites into orbit on 200th launch

SpaceX carried out its milestone 200th orbital mission on Friday (Dec. 16), sending up a pair of powerful new communications satellites.

A Falcon 9 rocket lifted off Friday from Space Launch Complex 40 at Florida’s Cape Canaveral Space Force Station at 5:48 p.m. EST (2248 GMT).  

The first stage, having done its job, came back down and landed safely on a SpaceX drone ship in the Atlantic Ocean just under nine minutes after liftoff. It was the reusable booster’s eighth touchdown overall.

The second stage, meanwhile, continued carrying the O3b mPower 1 and 2 satellites toward their intended medium Earth orbits (MEO). The satellites were deployed on schedule (opens in new tab) about two hours after launch.

O3b mPower 1 and 2 are owned and operated by SES, a Luxembourgish-French satellite telecommunications network company. The pair of spacecraft are the first of a planned constellation of an initial 11 high-throughput and low-latency satellites to provide multiple terabits of global broadband connectivity from MEO.

Each satellite is based on a Boeing BSS-702X satellite bus and features phased array antennas that can provide up to 5,000 spot beams to distribute hundreds of gigabits of capacity to users on the ground. SES plans to launch six more O3b mPower satellites in 2023 and three in 2024.

The mission marked SpaceX’s 200th orbital launch overall. These began with the Falcon 1, which flew five times between 2006 and 2009, leading to the first liftoff of the Falcon 9 on June 4, 2010. The Falcon 9 first stage is powered by nine Merlin engines, a fact contributing to the rocket’s name. The second stage uses a single, vacuum-optimized Merlin for completing the journey to orbit.

The launch rate of the Falcon 9 has increased dramatically over the years as the rocket has proven its reliability, versatility and reusability, while also evolving into its final Block 5 version. The rocket has now flown 191 missions, including a record 57 in 2022 alone. 

Four SpaceX orbital missions have been flown by the powerful Falcon Heavy, which employs three modified Falcon 9 first stages.

There will be little time for SpaceX to celebrate the 200-mission milestone. The company is scheduled to launch a big batch of its Starlink broadband satellites from NASA’s Kennedy Space Center in Florida on Saturday (Dec. 17).

Editor’s note: This story was updated at 8:30 p.m. EST on Dec. 16 with news of successful satellite deployment.

Watch a SpaceX rocket launch 2 telecom satellites into orbit today (Dec. 16)

Update for 6:31 pm ET: SpaceX successfully launched two SES Satellites into orbit at  5:48 p.m. EST (2221 GMT) for the company’s O3b mPower network, marking the 200th mission of a SpaceX booster and the eight flight for this Falcon 9 rocket. See launch video and read our wrap story.


SpaceX will launch two satellites for the telecom company SES on Friday (Dec. 16), and you can watch the action live.

A Falcon 9 rocket topped with SES’ O3b mPower 1 and 2 satellites is scheduled to lift off from Florida’s Cape Canaveral Space Force Station Friday during an 87-minute window that opens at 4:21 p.m. EST (2121 GMT). 

Watch it live here at Space.com courtesy of SpaceX or directly via the company (opens in new tab). Coverage is expected to begin about 15 minutes before launch.

If all goes according to plan, the Falcon 9’s first stage will come back to Earth for a soft landing on one of SpaceX’s robotic droneships in the Atlantic Ocean just under nine minutes after launch.

It will be the eighth liftoff and touchdown for this particular booster, acccording to a SpaceX mission description (opens in new tab). Four of its previous flights were missions to the International Space Station for NASA — two crewed and two uncrewed.

The Falcon 9’s upper stage will continue hauling the two satellites to orbit. The first is scheduled to be deployed into medium Earth orbit (MEO) one hour and 53 minutes after liftoff, and the second will follow suit seven minutes later.

O3b mPower 1 and 2 are the first two satellites of an 11-spacecraft constellation that SES plans to assemble in MEO. The satellites will provide high-throughput and low-latency communications for customers around the world, according to SES, which is headquartered in Luxembourg and France.

This mission is part of a busy stretch for SpaceX. The company launched the private Japanese Hakuto-R moon lander on Sunday (Dec. 11) and was scheduled to loft the SWOT water-monitoring satellite for NASA early Friday morning. 

SpaceX also plans to launch another big batch of its Starlink internet satellites from NASA’s Kennedy Space Center, which is next door to Cape Canaveral Space Force Station, on Saturday (Dec. 17).

China’s Pioneering Methane-Fueled Rocket Fails to Reach Orbit

An illustration of the Zhuque-2 rocket.
Illustration: Landspace

The Zhuque-2 rocket lifted off from the Jiuquan Satellite Launch Center in the Gobi Desert on Wednesday, leaving behind an unusual purplish trail—a product of its unique methane fuel. The rocket managed to take flight, but it failed to reach orbit and deliver the 14 satellites that were on board.

China’s private aerospace company Landspace was hoping to lead the way in utilizing methane—the next-generation rocket fuel—which is considered to be cleaner and safer than liquid hydrogen, kerosene, and other propellants currently in use. Liquid methane is also a good choice in terms of rocket reusability, a coveted capability for space companies.

The Beijing-based Landspace launched the doomed Zhuque-2 at 3:30 a.m. ET on December 14, in what was supposed to be the rocket’s first orbital mission. Following liftoff, the rocket’s second stage suffered an engine malfunction, resulting in mission failure, Landspace announced on Wednesday. Outside observers had already speculated that the mission was a failure before the company announced it.

Telemetry data suggests the rocket reached a speed of 11,000 miles per hour (5 kilometers per second), when it needed to reach around 17,500 miles per hour (7.8 kilometers per second) to maintain a stable orbit, according to Everyday Astronaut. The rocket was carrying a commercial payload of 14 satellites, all of them lost (not sure why the company thought it was a good idea to launch so many satellites on an unproven rocket, but whatever).

Despite its failure, the orbital test flight was still lauded as a major milestone for China, and its private space industry as a whole. The Chinese startup had attempted to launch a three-stage Zhuque-1 rocket, which used solid propellant, back in 2018. Zhuque-1 also failed to reach orbit, but the company is now set on switching to liquid methane as propellant instead.

Had Landspace been successful in launching the rocket to orbit, the company would’ve beat Elon Musk’s SpaceX in achieving this vaunted goal. SpaceX is also hoping to use liquid methane fuel to power its next generation Starship rockets, which are yet to fly. The company’s Falcon 9 and Super Heavy rockets use kerosene for fuel.

Even before its first orbital test flight, Landspace was already preparing for the second attempted launch of Zhuque-2, SpaceNews reported. The rocket’s second and third models are already in development, but Landspace is aiming to eventually make the rocket reusable, according to SpaceNews.

China is making significant headway with its spaceflight industry, both on the private and public front. In October, China launched the final module for its own space station in low Earth orbit, completing the ambitious project to rival the International Space Station. China also has some big plans for the Moon, setting up future launches that could compete with NASA’s Artemis program.

Launching the first ever methane-fueled rocket to Earth orbit would certainly give China a major advantage over other space programs. Of course, that all depends on how well the second launch attempt goes.

Star may have drawn scorching ‘hell planet’ into close orbit

You thought Venus was hot? 

While the planet does have an average surface temperature of nearly 900 degrees Fahrenheit (500 degrees Celsius), there’s an exoplanet just 40 light-years away from Earth that has a surface temperature a scorching three times hotter: 3,600 degrees Fahrenheit (2,000 degrees Celsius). Now, new data has led scientists to develop a theory of how this “hell planet” came to be. 

With a mass about eight times that of our planet, the rocky exoplanet 55 Cancri e (shortened to 55 Cnc e and formally called Janssen) is considered a super-Earth, but its surface conditions couldn’t be more different from those we enjoy. Janssen orbits its star, called 55 Cancri or Copernicus, at a distance of just 1.4 million miles (2.4 million kilometers), making the planet’s year just 18 hours long. By comparison, Mercury orbits about 36 million miles (58 million km) away from the sun. That proximity, of course, is what makes 55 Cancri e so hot — hot enough that the surface of the planet is an ocean of lava and its interior may be filled with diamonds.

Related: 7 ways to discover alien planets

Because of Janssen’s tight orbit, astronomers have had difficulty studying the planet. But using data from the new Extreme Precision Spectrometer (EXPRES) at the Lowell Observatory’s Lowell Discovery Telescope in Arizona, astronomers have for the first time been able to determine the planet’s orbital plane, influencing their theory for how the planet formed.

Unlike the other planets in the system, Janssen orbits around Copernicus’ equator. Researchers now believe the planet initially formed in a more distant — and thus cooler — location, then was later pulled into its current orbit by Copernicus’ gravity.

“We’ve learned about how this multi-planet system — one of the systems with the most planets that we’ve found — got into its current state,” Lily Zhao, an astrophysicist at the Flatiron Institute in New York and lead author of a new study on the observations, said in a statement.

The research into Janssen could unveil new discoveries about the formation and movement of planetary systems, which in turn could help scientists determine whether or not life might exist elsewhere in the universe. And that’s exactly what the team plans to study next.

“We’re hoping to find planetary systems similar to ours and to better understand the systems that we do know about,” said Zhao.

A study describing the team’s research was published Thursday (Dec. 8) in the journal Nature Astronomy (opens in new tab).

Rocket Report: SpaceX launch delayed indefinitely; Virgin Orbit cancels funding round

Enlarge / The Terran 1 rocket is shown in Relativity Space’s hangar in Florida.

Trevor Mahlmann

Welcome to Edition 5.19 of the Rocket Report! Back from the Thanksgiving holiday, there is a lot of news to get to this week, including a report card on the SLS rocket’s performance (excellent) and some wild and woolly news from north of the US border. Read on for more.

As always, we welcome reader submissions, and if you don’t want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets as well as a quick look ahead at the next three launches on the calendar.

Virgin Orbit ends security offering. The US-based launch company announced on the evening before Thanksgiving a “cessation” of a securities offering. “Due to current market conditions, the company has elected not to proceed with an offering,” Virgin Orbit said in a statement. “Any future capital raising transactions will depend upon future market conditions.” Previously, in October, Virgin Orbit CEO Dan Hart said the company was seeking to raise additional capital after going public as a special purpose acquisition company, or SPAC.

That’s not great, but … As part of the SPAC process, the company set a target to raise $483 million. However, the company only raised $228 million a year ago. Virgin Orbit has an excellent record of technical achievement, with four consecutive successes of its LauncherOne system. But there have long been questions about its financial viability, given the limited potential for growth with an air-launched rocket. This is certainly not the end of the road for Virgin Orbit, which is nearing a historic launch from Cornwall in the United Kingdom. Financially, it also has a hedge fund commitment to fall back on that is valued at $250 million.

ABL debut launch attempt is scrubbed. The first test flight of ABL Space Systems’ new small satellite launcher from Alaska has been delayed until no earlier than December after technical issues cut short a series of launch attempts in mid-November, Spaceflight Now reports. ABL conducted three countdowns during a week-long launch period at the Pacific Spaceport Complex on Kodiak Island, Alaska, to try to send aloft the company’s first RS1 rocket, which is capable of lifting 1 metric ton to low-Earth orbit.

Try again before Christmas … A November 14 launch attempt was scrubbed about 30 minutes before liftoff due to unexpected data during propellant loading on the RS1’s first stage, later found to be caused by a leaking valve in the pressurization system. A second launch attempt on November 17 was aborted at T-minus 1.8 seconds during ignition of its nine kerosene-fueled E2 first-stage engines. Another countdown on November 21 was also aborted during the engine startup sequence. That was the final launch attempt available to ABL until the company’s next series of launch dates begins on December 7. (submitted by EllPeaTea)

The easiest way to keep up with Eric Berger’s space reporting is to sign up for his newsletter, we’ll collect his stories in your inbox.

Electron picks up TROPICS launch contract. NASA said it selected Rocket Lab to provide the launch service for the agency’s Time-Resolved Observations of Precipitation Structure and Storm Intensity with a Constellation of Smallsats, or TROPICS, mission. Rocket Lab will launch four CubeSats for NASA on two Electron rockets, targeted for no earlier than May 1.

Ready to go for next year … This timeframe will enable NASA to provide observations during the 2023 Atlantic hurricane season, which begins June 1. The TROPICS constellation targets the formation and evolution of tropical cyclones, including hurricanes, and will provide rapidly updating observations of storm intensity. The launch of the first two TROPICS satellites, earlier this year on an Astra rocket, failed. (submitted by EllPeaTea and Ken the Bin)

Skyroot makes successful suborbital debut. Skyroot Aerospace successfully launched its small suborbital Vikram-S rocket on November 18, TechCrunch reports. The 6-meter-tall rocket reached an altitude of 89.5 km, as planned by the company, officials with the Indian startup said. The company is part of India’s nascent commercial space sector.

Orbit up next … Founded in 2018 by former ISRO scientists Pawan Kumar Chandana and Naga Bharath Daka, Skyroot has raised $68 million in total, including $51 million in a Series B round led by Singapore-based GIC in September. It has plans to develop a series of increasingly capable orbital “Vikram” rockets in the coming years. (submitted by Ken the Bin)

Relativity completes Terran 1 stacking. The company said it has successfully mated the first and second stages of the Terran 1 rocket ahead of a debut launch. “The next time Terran 1 is out on the pad, it will be stacked and vertical. Upcoming milestones to track: rollout, static fire, and launch,” the company said in its newsletter. The company also said it completed thrust vector control testing.

Slipping into the new year … Given that Relativity has yet to roll the Terran 1 out to the pad for its static fire test, it looks increasingly unlikely that the rocket will make its debut in 2022. However, the company is in good position to test its additively manufactured rocket early in 2023, perhaps even in January.

Phantom Space gets a NASA launch contract. Phantom Space—yes, the Phantom Space co-founded by Jim Cantrell—has received a “task order” from NASA to launch four CubeSats on the company’s Daytona rocket. The CubeSats will launch no earlier than 2024, NASA said, as part of the agency’s Venture-class Acquisition of Dedicated and Rideshare (VADR) program. This is NASA’s program to on-ramp a greater diversity of US rockets for government launch contracts.

Tolerating some higher risks … NASA will not launch any high-value satellites through VADR, which the agency says allows it to procure “commercial launch services for payloads that can tolerate higher risk.” There are currently 13 companies eligible to bid on VADR launch contracts, including established firms such as SpaceX and ULA, and less-established firms such as L2 Solutions in Houston. It will be interesting to see if Phantom Space can succeed in lofting the CubeSats for NASA. (submitted by Ken the Bin)

Australian launch facility raises environmental concerns. Conservationists say planned rocket launches on the Eyre Peninsula in South Australia pose an extinction-level threat to the wren, one of Australia’s smallest birds, The Guardian reports. The subspecies of southern emu-wren at the site is listed as endangered under existing law but as vulnerable nationally. Australia’s environment minister, Tanya Plibersek, is considering lifting the national status to endangered. That change would matter for project approvals and funding decisions for the Southern Launch spaceport.

Regulatory approval is pending … The Nature Conservation Society of SA says land clearance, disturbance by humans, including noise, vibrations and cars, as well as an increased risk of bushfire, put the bird at extreme risk. The Southern Launch chief executive, Lloyd Damp, said the company had engaged “pre-eminent independent experts” as part of its environmental impact statement. “The outcomes show we will have a very positive effect on their habitat through environmental management such as feral animal eradication programs,” he said.

This Canadian company has ambitions, baby! I confess to not having heard of Edmonton-based Space Engine Systems until a spaceQ story crossed my desk this week. There’s a lot going on here, but if I may try to summarize, the company is working on a) a single-stage-to-orbit space plane, b) a hypersonic vehicle for point-to-point transport of body organs for medical transplants, c) a Moon-capable spacecraft, and d) a hypersonic drone named “Sexbomb” for defense applications.

That’s a full plate … Like I said, a lot is happening here. And it’s difficult to divine whether any of this is real. I suspect the answer is no, it’s not. But it makes for fun reading. Make sure you check out the image at the top of the article, which appears to be a comically low-fidelity rendering of a “high temperature wing bending test facility.” Something is bent, that’s for sure.

Artemis 1 Orion spacecraft leaves moon’s orbit to head home

NASA’s Artemis 1 Orion spacecraft is coming home.

The uncrewed Orion spacecraft successfully completed a lunar departure burn on Thursday (Dec. 1) to begin heading home after successful moon orbits. The burn began at 4:54 p.m. EST (2154 GMT) and lasted just under two minutes, according to NASA Television commentator Shaneequa Vereen. 

“Orion has had a successful and nominal, 1 minute and 45 second, distant retrograde orbit departure burn,” Vereen announced during the agency’s broadcast of the burn. The spacecraft’s solar panels could be seen gently rocking back and forth on NASA Television’s live broadcast as a “tiny Earth” glowed in the background.

Orion now begins its ten-day trek home. If all goes according to plan, the capsule will splash down in the Pacific Ocean off the coast of California on Dec. 11. NASA and the United States Navy have already begun training for the recovery operation that will mark the end of the Artemis 1 mission.

Live updates: NASA’s Artemis 1 moon mission

Orion launched atop NASA’s massive Space Launch System (SLS) rocket in a fiery display on Nov. 16, kicking off the space agency’s highly-anticipated Artemis 1 moon mission.

The mission is the first in the agency’s Artemis program, which is aimed at establishing a sustainable crewed lunar outpost near the moon’s south pole by the end of the decade.

The first Artemis mission was intended as a test for both the SLS vehicle and Orion spacecraft to ensure that both are flightworthy and safe to carry human crews into deep space. If Artemis 1 goes as planned, the next mission, Artemis 2, will launch astronauts into orbit around the moon in 2024. NASA will then return astronauts to the moon no earlier than 2025 with Artemis 3

So far, Artemis 1 has met its benchmarks, according to NASA. Mission managers announced on Wednesday (Nov. 30) that the Nov. 16 launch of SLS showed the vehicle performed exactly as intended.

“The first launch of the Space Launch System rocket was simply eye-watering,” Artemis mission manager Mike Sarafin said. “While our mission with Orion is still underway and we continue to learn over the course of our flight, the rocket’s systems performed as designed and as expected in every case,” he added.

Orion, meanwhile, has been likewise performing wonderfully by all indications. A major milestone, the spacecraft’s insertion into a distant retrograde orbit around the moon, was achieved on Nov. 25

With today’s burn, Orion now has a long and lonely journey home, and will no doubt be sending home gorgeous images and footage as it has throughout its flight so far.

Orion successfully entered into distant retrograde orbit (DRO) on November 25, but now the spacecraft will move to a trajectory that will take it back to Earth. The requisite departure burn is scheduled for today at 4:53 p.m. ET, with NASA coverage starting at 4:30 p.m. ET. You can follow along at NASA TV, YouTube, or at the live stream below.

The DRO departure burn will send Orion on a trajectory that will take it to within 80 miles (128 kilometers) of the lunar surface, which will happen on December 5, or day 20 of the Artemis 1 mission. During this close lunar approach, Orion will perform another course correction burn at 11:43 a.m. ET. NASA expects to gather more detailed images of the Moon during the flyby, similar to Orion’s first lunar flyby on November 21.

Orion made history earlier this week when it reached its maximum distance from Earth. At approximately 268,558 miles (432,194 km) from home, it’s the farthest that any crew-rated vehicle has ventured away from our home planet.

Orion launched to space atop NASA’s Space Launch System (SLS) rocket on November 16. The purpose of this, the debut mission of the Artemis era, is for NASA to demonstrate the new rocket and an uncrewed Orion spacecraft. For Artemis 2, currently scheduled for 2024, NASA will perform a repeat of this mission but with four astronauts along for the ride. This is all prelude to the ultimate goal: landing a man and a woman on the lunar surface later this decade.

Artemis 1 appears to be going exceptionally well, with both SLS and Orion doing exactly what they’re supposed to do. The mission management team met yesterday, giving the “go” to proceed with today’s DRO departure burn.

“We are continuing to collect flight test data and buy down risk for crewed flight,” Mike Sarafin, Artemis mission manager, said in a statement. “We continue to learn how the system is performing, where our margins are, and how to operate and work with the vehicle as an integrated team.”

Orion will reach Earth on December 11 and perform a splashdown in the Pacific Ocean at 12:42 p.m. ET. Well, assuming the spacecraft survives atmospheric reentry, in which Orion’s heat shield must endure temperatures in excess of 5,000 degrees Fahrenheit.
