The Intuitive Machines Odysseus lunar lander carries precursor instruments of the International Lunar Observatory Association (ILOA Hawai’i), dedicated to a long-term goal of permanent astronomy from the Moon.
While the lander is apparently tipped over, there are two ILO-X precursor imagers mounted near the top of the lander. Team members of the ILOA remain hopeful to receive images from the Moon.

Cautiously optimistic
In a statement from ILOA director Steve Durst: “We remain cautiously optimistic that ILO-X and our fellow passenger payloads aboard Intuitive Machines’ lander are able to gather as much science and data as possible during this time.”
ILOA is an interglobal enterprise to help realize the multifunctional ILO for long-term astronomy, science and exploration at the Moon’s south pole, and to participate in human lunar base build-out, the group’s statement adds.
“These flagship ILOA Missions will be designed for strategic lunar locations on Malapert Mountain and Shackleton Crater Rim,” Durst noted in an earlier press statement.

Pre-launch aim
As noted in the IM-1 press kit, ILO-X is a precursor to the ILOA Hawai’i flagship lunar south pole Observatory (ILO-1).
The roughly 0.6 kilogram ILO-X instruments, built for ILOA by Toronto-based Canadensys Aerospace, include a miniaturized dual-camera lunar imaging suite: one wide field and one narrow field.
The aim of ILO-X is to capture some of the first images of the Milky Way Galaxy Center from the surface of the Moon, as well as perform other /Earth/local lunar environment observations and exploration technology validations – including functionality and survivability on the Moon.

EagleCam deployment
In other developments, Odysseus ground teams are upbeat on launching from the lander the EagleCam, a camera system from Embry‑Riddle’s Space Technologies Lab.
It was intended to be ejected from the lander on approach to the Moon. While the lander is likely on its side, EagleCam’s deployment is not obstructed for launch.
The EagleCam team at Embry-Riddle is currently running simulations of a deployment. Their current, but tentative estimate, is that the camera gear could land somewhere between 10 to 16 feet (3-5 meters) from the lander. When EagleCam deployment will occur is not known at this time.

EagleCam could capture imagery of the lander on the Moon. Once ejected, the device may observe the lander and help gauge its overall condition upon the lunar surface.
Meanwhile, NASA’s Lunar Reconnaissance Orbiter (LRO) will be flying over the target area on February 24th. Using LRO’s high-powered camera system, the true-whereabouts of Odysseus may be determined.
Also, India’s Chandrayaan-3 lunar orbiter should be able to train its sharp-eyed, camera-toting capability on the Odysseus landing site.

The Intuitive Machines Moon lander carried EagleCam, a camera system from Embry‑Riddle’s Space Technologies Lab, that was to be ejected from the lander on approach to the Moon.
EagleCam was billed and able to capture the first-ever third-person picture of a spacecraft making an extraterrestrial landing.

Power down
New information from Troy Henderson, faculty lead of the EagleCam team, points out that due to complications with Odysseus’ internal navigation system, meant to ensure a soft landing, the “decision was made to power down EagleCam during landing and not deploy the device during Odysseus’ final descent.”
However, Henderson added that both the Intuitive Machines and EagleCam teams still plan to deploy EagleCam “and capture images of the lander on the surface as the mission continues.”
That complication with Odysseus’ navigation system specifically involved a software patch to navigation data to include NASA’s NDL (navigation doppler lidar) payload to make sure a soft landing on the Moon occurs.

The prolonged wait for the true status of the private Moon lander, Odysseus, is indeed a nail-bitter blended in with the sounds of silence
According to Intuitive Machines, the status of the recent arrival on the Moon is that the lander is “alive and well.” At this posting, no surface imagery has been released.
Reportedly, flight controllers are communicating and commanding the vehicle to download science data.
“The lander has good telemetry and solar charging,” according to Intuitive Machines.

Overall health
What’s ahead is trying to figure out more about the Odysseus vehicle’s latitude and longitude, overall health, and attitude (orientation).
Intuitive Machines CEO Steve Altemus will participate in a press conference later today, hopefully filling in the blanks.
Facing Earth
But from master satellite tracker, Scott Tilley in an X (Twitter) posting:
“Yes, imagine you are a box. Only one side of you (a box) has a mouth and your voice will only carry for a very limited angular cone and your mouth can’t move much to re-aim. So if you landed in the wrong location or with the wrong side of your box facing Earth…No one hears you.”

Following lunar orbit insertion on February 21st, Intuitive Machines notes its lander is in excellent shape for Odysseus’ “hardest challenge yet” – an expected 1630 Central Standard Time (5:30 p.m. Eastern Time) landing opportunity.
Odysseus is orbiting approximately 57 miles (92 kilometers) above the lunar surface.

The European Space Agency has issued what may be the final update prior to the uncontrolled fiery finale and destruction of the European ERS-2 spacecraft.
Using data acquired in the last few hours, ESA’s Space Debris Office predicts that the reentry of ESA’s ERS-2 satellite will take place today, on Feb. 21 at 15:41 UTC (16:41 CET) .
The uncertainty in this prediction is +/- 1.44 hours.

A European Space Agency spacecraft is making an uncontrolled nosedive into Earth’s atmosphere – with elements of the 2.3-ton spent satellite likely to survive the plunge into purgatory.
The exact time and place above Earth that the radar-scanning ESA European Remote Sensing (ERS-2) augers in is unknown, but a new prediction of the spacecraft’s demise has been issued.

Using data acquired on February 20, ESA’s Space Debris Office currently predicts that the reentry of ESA’s ERS-2 satellite will take place at 20:53 UTC (21:53 Central European Time) February 21.
The uncertainty in this prediction is now just (+/- 7.48 hours), according to an ESA statement.
“This uncertainty is due primarily to the influence of unpredictable solar activity, which affects the density of Earth’s atmosphere and therefore the drag experienced by the satellite,” ESA adds.

Leftovers
As for the ERS-2 re-entry itself, there’s likely to be post-re-entry spacecraft leftovers.
“It is likely that some parts survive the re-entry, as on average between 10 and 20 percent of the mass for large objects does,” says Simona-Elena Nichiteanu, a media relations officer in the communication department at the European Space Operations Centre (ESOC).
ESOC serves as the main mission control center for ESA in Darmstadt, Germany.

Component survival
As for the ERS-2 component survival to Earth’s surface, Nichiteanu told Inside Outer Space that the biggest and heaviest fragments that might survive reentry into the atmosphere are the 4 tanks (heaviest), the 3 internal panels supporting instruments (largest cross section) and the Synthetic Aperture Radar (SAR) antenna structure (largest fragment assuming it does not fragment at all).
A vast majority of ERS-2 will “burn up” in the atmosphere, ESA experts explain. Furthermore, given that the Earth is largely ocean water-rich, chances are for splash down of any remaining spacecraft components.
Orbital debris regulation
The fall of ERS-2 can be viewed both as a calling card from space and a wake-up call.
“While the ESA should be lauded for its efforts to de-orbit the ERS-2, it should be unsurprising that a 2.3-ton satellite launched into Earth orbit without any enforceable orbital debris regulation will then return to Earth’s atmosphere as orbital debris in an explosive uncontrolled reentry,” said Michael Runnels, an assistant professor of business law at California State University, Los Angeles.
“Indeed, these events highlight the continuing need for enforceable orbital debris regulation to support the sustainable exploration and scientific investigation of outer space,” Runnels told Inside Outer Space.

That incoming European Remote Sensing (ERS-2) is closing in on a nose-dive into Earth’s atmosphere.
Tipping the scales at an estimated 2.3 tons (2,294 kilograms), when and where the defunct spacecraft completes its final orbit is an unknown. ERS-2 was launched on April 21, 1995.
Meanwhile, the European Space Agency’s (ESA) latest prediction is that ERS-2’s demise is now heading toward re-entry on February 21 at 15:19 UTC (16:19 Central European Time).

“The uncertainty in this prediction is now less than one day (+/- 18.82 hours),” ESA satellite trackers add. “Please note that all predictions are still affected by significant uncertainties.”
Breaking up – easy to do?
ERS-2 will break up into fragments as it plunges through Earth’s atmosphere.
A vast majority of these will “burn up” in the atmosphere, ESA experts explain, although some fragments could reach Earth’s surface. Given that the Earth is largely ocean water-rich, chances are for splash down of any remaining spacecraft components.

“No intervention can be made from the ground, so ERS-2 will return entirely naturally – now a common occurrence as on average one spacecraft reenters Earth’s atmosphere per month,” an ESA statement explains.
Entirely naturally
However, there are those that see the fall of ERS-2 as a calling card from space that doubles as a wake-up call – and on several fronts.

ERS-2 is a three decade old Earth Observation satellite with a mass about that of a Ford F-150, Wright said. “ERS-2 won’t burn up entirely when it reenters the atmosphere, so there is a chance that debris will hit someone on the ground, or disrupt air traffic.”
Uncontrolled re-entry
Wright told Inside Outer Space that, fortunately, the probability of someone getting hit is small. “But if we keep doing this again and again, someone someday will get hurt.”
Last year, 30 satellites larger than 500 kilograms uncontrollably reentered the atmosphere.
In total, in 2023, about 55 tons of satellite reentered randomly, Wright stated. ESA was responsible in lowering ERS-2’s orbit to make sure it didn’t become permanent space debris, he said.

“But in the future, all large satellites should do controlled reentries. Operators should control them to reenter over the oceans, away from people, aircraft and ships,” Wright concluded.
Hot topic
The incoming ERS-2 is something that happens quite regularly with defunct satellites, said Leonard Schulz, a researcher at the Technische Universität Braunschweig’s Institute of Geophysics and Extraterrestrial Physics in Braunschweig, Germany.
Such falls will only increase in the future, Schulz added, due to the growing number of objects brought into low Earth orbit.
Schulz said that there’s need to consider the effects on the atmosphere from spacecraft re-entry, a hot topic that ESA is evaluating.
“Today, we are lacking information on many aspects when it comes to materials released and subsequent effects on the atmosphere,” Schulz pointed out to Inside Outer Space.
Satellite reentries are a good opportunity to gather observational data with measurement campaigns, Schulz advised. However, such uncontrolled reentries as with ERS-2 are extremely difficult to observe, he said, as the uncertainty of where the satellite reenters is so high.

“But controlled reentries provide great measurement opportunities,” Schulz concluded, “which should be a focus in the future!”
Long-term impact
ESA organized a dedicated event in January 2024 to address the topic of satellite leftovers and pollution within Earth’s atmosphere.
ESA also carried out two studies on the atmospheric impact of spacecraft reentries in 2019. They concluded that the short-term impact on the atmosphere due to the burn up of a single spacecraft is modest, primarily because the particles created during a reentry are generally too large to react chemically with the atmosphere.

On the other hand, what about long-term impact?
In a recent study issued last year, a research team led by the U.S. National Oceanic and Atmospheric Administration (NOAA) detected in Earth’s stratosphere more than 20 elements that mirror those used in spacecraft-building alloys.
Given projected launch rates from countries around the world, the NOAA research team calculated that in the next few decades, up to half of stratospheric sulfuric acid particles would contain metals from reentry.
Difficult to study, complex to understand
But what impact these space junk-laden particles could have on the atmosphere, the ozone layer and life on Earth is yet to be evaluated.

“Changes to the atmosphere can be difficult to study and complex to understand,” explains Purdue University’s Daniel Cziczo, professor and department head of Earth, Atmospheric, and Planetary Sciences. He took part in the NOAA-issued report.
“But what this research shows us is that the impact of human occupation and human spaceflight on the planet may be significant,” Cziczo adds, “perhaps more significant than we have yet imagined. Understanding our planet is one of the most urgent research priorities there is.”

The reentry of Varda Space Industries’ in-space manufacturing capsule, named Winnebago-1 (W-1), is set for February 21.
The FAA has granted a world-first reentry license for the mission, enabling Rocket Lab to conduct a targeted reentry of the capsule and subsequent landing in the Utah Desert.
Rocket Lab built and is operating the spacecraft currently hosting the capsule on orbit.
Varda’s W-1 mission was lofted on SpaceX’s Transporter 8 flight last June.

However, Varda’s initial plan to reenter the capsule back in September of last year was curtailed due to both Air Force and FAA approval issues.
Engine burns
In the coming days, Rocket Lab will conduct a series of maneuvers to bring the capsule, named Winnebago-1, back to Earth.
The Varda capsule is approximately 3 feet in diameter, 2.5 feet tall, and weighs less than 200 pounds. It is slated to parachute into the Utah Test and Training Range (UTTR) – a remote area in which NASA’s OSIRIS-REx asteroid return capsule also landed last year.
In the evening of February 18, Pacific Time (PT) there will be an initial burn of the Curie engine on Rocket Lab’s spacecraft that places Winnebago-1 in its first staging orbit.
On February 20, PT, a second engine burn places Winnebago-1 in its second staging orbit.

Afternoon of February 21, PT, the spacecraft’s third and fourth final engine burns to de-orbit and set Winnebago-1 on its atmospheric reentry trajectory.
First of four
The Varda capsule was lofted to grow Ritonavir crystals, a drug commonly used as an antiviral medication for HIV and hepatitis C.
According to a Rocket Lab statement, this mission is the first of four which will use identical Rocket Lab spacecraft to support Varda’s in-space manufacturing.
“The second spacecraft has completed assembly, integration, and testing at Rocket Lab’s spacecraft production facility in Long Beach, California, and is scheduled to launch in the coming months,” adds the statement.

The Intuitive Machines (IM-1) Moon lander has transmitted its mission images to Earth on February 16th.
The lunar lander images were captured shortly after separation from the SpaceX’s second stage.
The IM-1 mission Nova-C class lunar lander called “Odysseus” continues to be “in excellent health, in a stable orientation and remains on schedule for a lunar landing opportunity on the afternoon of February 22,” according to an earlier IM-1 posting from the private group.
Intuitive Machines flight controllers have successfully fired the first liquid methane and liquid oxygen engine in space, completing the IM-1 mission engine commissioning.
This engine firing included a full thrust main stage engine burn and throttle down-profile necessary to land on the Moon, the company reports.
Commission maneuver
There was a delay in a spacecraft Commission Maneuver burn on February 15.
“This approach provided flexibility in the mission’s engine burn schedule to allow for learning as we operate the lander in the vacuum of space,” the private company explains. Adjusting for this learning process is why the team chose to delay the burn.

While preparing for the CM burn, flight controllers experienced intermittent uplink and downlink data communications between the Nova-C lander and ground stations, potentially impacting our ability to collect the critical information required to support the CM burn and follow-on performance analysis.
“As we prepared for the first-ever in-space ignition of a liquid methane and liquid oxygen engine, we reviewed our Earth-based test data against the data we’ve accumulated in space,” the communiqué from Intuitive Machines explains.

Chill out
“The in-space performance demonstrated that it takes longer to chill the liquid oxygen feed line than the Earth-based testing. After understanding the in-space liquid oxygen feedline requirements, we adjusted and uploaded the CM burn preparation timeline and increased the onboard event sequence timer.”
The IM-1 mission Nova-C class lunar lander “is in excellent health, and we expect to continue to provide mission updates at least once a day,” explains the posting.
