Engineers Are Racing to Salvage Cubesat for Moon Mission
A mission to measure lunar water-ice on the Moon is in jeopardy after the cubesat failed to fire its engines shortly after launch. Time is now running out, as the team has until mid-January to fix the spacecraft’s thrusters and give it a second chance to enter lunar orbit.
NASA’s LunaH-Map, manufactured by Arizona State University, was one of 10 cubesats launched on November 16, 2022 as secondary payloads aboard the Artemis 1 mission. The tiny probe was one of six cubesats cable of sending radio signal to ground teams, in what was an upsetting rate of attrition.
Things were looking good for LunaH-Map until the following day, when mission controllers tried to engage the cubesat’s propulsion system and execute a crucial course correction maneuver. Despite several attempts, the spacecraft failed to fire its engines, preventing it from performing its intended lunar flyby on November 21. LunaH-Map was supposed to use this propulsive maneuver to direct it towards its orbit around the Moon.
Engineers are hoping to fire LunaH-Map’s thrusters in the coming weeks such that the spacecraft can take an alternate route to the Moon, Craig Hardgrove, principal investigator for LunaH-Map at Arizona State University, said during a presentation about the mission at the Fall Meeting of the American Geophysical Union in December, SpaceNews reported. The team has until mid-January to do so, otherwise the probe will never reach any kind of orbit around the Moon.
G/O Media may get a commission
Data collected so far suggests that a valve within the spacecraft’s thrusters is partially stuck. Engineers are attempting to use heaters in the propulsion system to free the valve. Should the spacecraft miss its second shot at entering lunar orbit, the mission team will consider sending LunaH-Map towards a near-Earth asteroid, according to Hardgrove.
While NASA’s Artemis 1 mission was a success, its secondary payload has not been so lucky, with the majority of cubesats packed for the lunar mission failing at some point after launch. The mission suffered several delays and engineers were only able to recharge four out of 10 cubesats already packed inside the Space Launch System (SLS) rocket. NASA was worried that its LunaH-Map cubesat would not have enough power to endure the journey to the Moon and complete its mission of measuring water-ice in the shadowed regions of the lunar surface, but this proved to not be a problem. The jammed valve is another story.
It won’t be long before we find out LunaH-Map’s fate once and for all, but hopefully this tiny probe can make it all the way to the Moon.

Russian engineers assessing leak from Soyuz crew spacecraft – Spaceflight Now
A Russian Soyuz crew ferry ship docked to the International Space Station spewed particles of an unknown substance, presumably coolant fluid, into space Wednesday night, forcing two Russian cosmonauts to call off a planned spacewalk as engineers on the ground scrambled to determine the source and the effects of the leak.
Mission controllers first observed the leak around 7:45 p.m. EST Wednesday (0045 GMT Thursday), according to Rob Navias, a NASA spokesperson providing commentary on NASA TV. The leak occurred as Russian cosmonauts Sergey Prokopyev and Dmitri Petelin prepared for a spacewalk to help relocate a radiator from outside of the Russian Rassvet module to the Nauka science module on the space station.
But before the cosmonauts could head outside, Russian ground controllers near Moscow noticed “significant leaking of an unknown substance from the aft portion of the Soyuz MS-22 spacecraft docked to the Rassvet module on the International Space Station,” NASA said in a brief statement Wednesday night.
Navias said Russian ground teams noticed a warning tone indicating a drop in pressure in an external cooling loop on the Soyuz spacecraft when the spray of snow-like particles were first observed streaming away from the capsule.
The Soyuz MS-22 spacecraft has been leaking apparent coolant fluid more than three hours. International Space Station managers are discussing the situation.

There are two manifolds in the Soyuz spacecraft’s single cooling loop, Navias said. It wasn’t immediately clear what impact the apparent coolant leak might have on the performance of the Soyuz spacecraft, which launched Sept. 21 from the Baikonur Cosmodrome in Kazakhstan with Prokopyev, Petelin, and NASA astronaut Frank Rubio.
“The spacewalk has been canceled, and ground teams in Moscow are evaluating the nature of the fluid and potential impacts to the integrity of the Soyuz spacecraft,” NASA said in a statement.
“The experts in Moscow are going to be taking a look at their systems and responding to the leak according to their procedures and policies,” said Emily Nelson, NASA’s lead flight director at the Johnson Space Center in Houston. “Once they have a good understanding of the final status of the Soyuz tonight, we will then jointly make a decision about where to go forward from here.”
Navias said there is no danger to the crew from the apparent coolant leak, but officials will need to sort out the condition of the Soyuz MS-22 spacecraft, which is the lifeboat and the ride home for three of the crew members on the International Space Station.
“The best plan of action tonight was to focus all of our attention, all of our Moscow team’s attention, to sort out what’s going on exactly with the Soyuz spacecraft, and we’ll regroup tomorrow,” Nelson said Wednesday night.
Russian engineers were also assessing whether the leak might have been caused by an impact with space junk or a micrometeoroid, or whether it could have been triggered by a problem on the Soyuz spacecraft.
The Soyuz MS-22 spacecraft is scheduled to return to Earth with Prokopyev, Petelin, and Rubio on March 28. Until then, the spacecraft serves as the emergency lifeboat for the three-man crew that launched aboard it in September. If Russian officials determine the Soyuz MS-22 spaceship is unable to bring the crew home, a replacement Soyuz could be launched from Baikonur without anyone on-board to automatically dock with the station.
But it’s unclear when the next Soyuz in line, Soyuz MS-23, could be ready for launch. It is currently scheduled to take off March 16 with Russian cosmonauts Oleg Kononenko, Nikolai Chub, and NASA astronaut Loral O’Hara to begin a six-month expedition.
Russian ground controllers instructed cosmonauts on the Russian segment of the station to take zoomed-in photos of the instrumentation and propulsion module on the Soyuz MS-22 spacecraft, the apparent origin of the leak.
There are currently seven crew members on the International Space Station. A SpaceX Crew Dragon spacecraft is also docked to the U.S. segment of the outpost after arriving Oct. 6 with NASA astronauts Nicole Mann, Josh Cassada, Japanese astronaut Koichi Wakata, and Russian cosmonaut Anna Kikina.
Working from a control panel inside the station, Kikina extended the European robotic arm to survey the Soyuz MS-22 spacecraft after the leak.
The next SpaceX Crew Dragon mission is scheduled for launch Feb. 19 from Kennedy Space Center in Florida with two NASA astronauts, an astronaut from the United Arab Emirates, and a Russian cosmonaut.
Two Russian Progress resupply ships and a Northrop Grumman Cygnus cargo freighter are also attached to the space station.

NASA engineers added more Orion tests to mission (video)
Artemis 1 is almost home, and NASA is readying for the next stages already.
The Orion spacecraft of Artemis 1 is expected to splash down in the Pacific Ocean on Sunday (Dec. 11), and the agency is already looking ahead to future missions of the Artemis program.
“Artemis 1 and Orion have been phenomenal,” Nujoud Merancy, chief of the exploration mission planning office at NASA’s Johnson Space Center, told Space.com in a video interview. Orion was tasked with flying around the moon to collect data for future crewed missions and so the mission has been performing so well, with only minor glitches, that NASA felt comfortable adding more tasks to the manifest.
“The whole point [and] purpose of this mission was to validate that we designed the rocket and the spacecraft right, and it’s exceeding expectations to the point we were actually adding objectives with Orion,” Merancy added.

The primary objective of the Artemis 1 mission will be completing the high-speed re-entry and splashdown, which is so far on track for Sunday (Dec. 11). The mission also achieved other key objectives, such as testing the unflown Space Launch System and flying in a distant retrograde orbit around the moon to assess readiness for human occupancy of the Orion spacecraft.
More analysis will come after splashdown to see how well Orion did, Merancy said. “All of the data recorded during the mission, the engineers and the teams will be going back through it to make sure that it matched our predictions. That’s really the forward plan.”
When Artemis 2 flies around the moon with astronauts in about 2024, it will be a test of Orion’s life support systems as those were not included in Artemis 1. The crew has not yet been announced, but the mission design is already completed, Merancy said.
Following that will be the first crewed landing of the moon, which is expected to be in 2025 or so with Artemis 3, which will begin a series of excursions to the south pole of the moon along with NASA’s planned Gateway space station in orbit.
“There’s just so much to do,” Merancy added of the mission planning, but added that the Artemis team will be taking some time to celebrate the success of Artemis 1 during the splashdown.
“There’s going be a viewing party here at Johnson, on Sunday, to watch it happen,” Merancy said. “I’ll be bringing the family, and we’ll be here to celebrate like everyone else.”

Day After 1,200 Twitter Employees Resign, Elon Musk’s SOS To Engineers
Twitter closed its offices yesterday after hundreds of employees resigned.
New Delhi:
A day after hundreds of Twitter employees decided to resign, owner Elon Musk sent an SOS to the staff: Anyone who writes software, please report to the 10th floor at 2 pm today. Musk, in an email, asked software engineers to fly to San Francisco and be at the Twitter office in person.
Musk added that only those who can’t physically get to the Bay Area or have family emergencies will be excused from attending, reports Bloomberg.
The Twitter owner asked the engineers to send a bullet-point summary of their coding accomplishments in the last six months, along with as many as 10 screenshots of the most salient lines of code. Musk said the meetings will be short, and are being held to help him “understand the Twitter tech stack.”
The mail came hours after Twitter was forced to close its office after a mass exodus over Musk’s ultimatum to commit to an “extremely hardcore” work environment. Musk had asked the staff to choose between working intense long hours, or losing their jobs.
At least 1,200 employees resigned yesterday creating a cloud of confusion over which people should still have access to company property, reports New York Times.
Musk, the world’s richest man, has come under fire for radical changes at the social media company, which he bought for $44 billion late last month.
He had already fired half of the company’s 7,500 staff, scrapped a work-from-home policy, and imposed long hours, all while his attempts to overhaul Twitter have faced chaos and delays.

Engineers assessing hurricane-damaged insulation before Artemis launch Wednesday – Spaceflight Now
STORY WRITTEN FOR CBS NEWS & USED WITH PERMISSION
NASA managers cleared the agency’s leak-bedeviled Artemis moon rocket for the start of another countdown early Monday, but engineers must resolve questions about hurricane-damaged insulation before the huge booster can be cleared for blastoff on an unpiloted moonshot.
After multiple delays due to hydrogen fuel leaks and other glitches, along with the rocket’s nail-biting brush with Hurricane Nicole last week, NASA managers met Sunday to review launch preparations and agreed to start a 47-hour 10-minute countdown at 1:54 a.m. EST Monday. Launch is planned for 1:04 a.m. Wednesday.
But high winds from Nicole caused a thin strip of caulk-like material known as RTV to delaminate and pull away from the base of the Orion crew capsule’s protective nose cone at the top of the rocket.
The material is used to fill in a slight indentation where the fairing attaches to the capsule, minimizing aerodynamic heating during ascent. The fairing fits over the Orion capsule and is jettisoned once the rocket is out of the dense lower atmosphere.
“It was an area that was about 10 feet in length (on the) windward side where the storm blew through,” said mission manager Mike Sarafin. “It is a very, very thin layer of RTV, it’s about point-two inches or less … in thickness.”
Engineers do not have access for repairs at the pad and must develop “flight rationale,” that is, a justification for flying despite the delaminated RTV, in order to proceed with the launch. Managers want to make sure any additional material that pulls away in flight will not impact and damage downstream components.
The issue is reminiscent of a debate following a foam debris incident in October 2002 that dented an electronics assembly at the base of a shuttle booster. In that case, NASA opted to continue flying while engineers developed a fix. Two flights later, another foam impact fatally damaged the shuttle Columbia’s left wing.
Sarafin said the SLS rocket, making an unpiloted test flight, “is a fundamentally different vehicle design.”
“The vehicle in this case is taller, and we do need to take that into account,” he said. “But in terms of hitting critical components … the physics are the same, the analysis is very similar, but where critical components are located (is) just fundamentally different.”
In any case, NASA’s mission management team plans to meet again Monday to review the flight rationale and determine if the countdown can proceed to launch.
If all goes well, the launch team will begin pumping 750,000 gallons of supercold liquid oxygen and hydrogen fuel back into the huge rocket’s tanks starting just before 4 p.m. Tuesday, using revised “kindler, gentler” techniques to control temperatures and minimize sharp pressure jumps to prevent leaks in critical seals.
If any problems do show up, engineers will have two hours to resolve them before the launch window closes.
But the weather is 90 percent “go” and if the fueling procedures work as intended, the 322-foot-tall Space Launch System rocket’s four shuttle main engines and extended strap-on solid-fuel boosters should finally roar to life at 1:04 a.m. Wednesday, opening a new era in American space flight.
Briefly turning night into day as it climbs away atop 8.8 million pounds of thrust, the 5.7-million-pound SLS will quickly accelerate as it consumes propellants and loses weight, passing through the speed of sound in less than one minute.
The two strap-on boosters, which provide the lion’s share of the rocket’s initial thrust, will burn out and fall away about two minutes and 10 seconds after liftoff. The four hydrogen-fueled engines powering the core stage will shut down six minutes later, putting the Orion capsule and the SLS second stage into an initial elliptical orbit.
After raising the low point of the orbit, the single engine powering the Interim Cryogenic Propulsion Stage, or ICPS, will fire again about 90 minutes after launch to break out of Earth orbit and head for the moon. The Orion capsule and its service module will separate a few minutes later to continue the rest of the trip on their own.
The goal of the Artemis 1 mission is to send the Orion spacecraft on a looping trajectory beyond the moon in a critical test of the vehicle’s propulsion, navigation and solar power systems before returning to Earth for a 5,000-degree re-entry and splashdown in the Pacific Ocean west of San Diego.
If the Artemis 1 flight goes well, NASA plans to launch four astronauts atop a second SLS for a lunar shakedown mission — Artemis 2 — in late 2024, followed by an astronaut landing mission in the 2025-26 timeframe.
But that assumes the Artemis 1 flight goes well. As Jim Free, director of exploration systems at NASA Headquarters, put it Friday, “we’re never going to get to Artemis 2 if Artemis 1 isn’t successful.”
