We’ve been incredibly efficient with our use of propellant on #Artemis I so far. As of Nov. 21, we've used a total of 3.7K lbs of propellant, 76 lbs less than expected. We have 2.1K lbs of margin available over what we planned for use, an increase of 201 lbs from expected values.

Huge Artemis 1 moon rocket blew the doors off its launch tower's elevators (video)

By Elizabeth Howell published about 19 hours ago

NASA's powerful new moon rocket damaged its launch pad and blew away elevator doors in the launch tower during its inaugural liftoff last week.

"The damage that we did see pertains to really, just a couple of areas," emphasized NASA's Mike Sarafin, Artemis mission manager, in a press conference with reporters on Monday (Nov. 21).

Like the space shuttle before it, Artemis 1's launch used a water suppression system to reduce the amount of damage to the launching deck, which worked as expected. Nevertheless, paint was peeled off the deck of Artemis 1's launch tower due to the sheer force of the liftoff, Sarafin said.

The elevators for servicing the launch tower fared less well, with photos showing crooked framing around at least one of the two lifts after the doors were ripped away by the shock wave generated by the SLS.

"The elevator system is not functioning right now," Sarafin explained. "The pressure basically blew the doors off our elevators ... right now, the elevators are inoperable, and we need to get those back into service."

Minor damage was induced to the pneumatic lines associated with gaseous nitrogen and gaseous helium to service the massive SLS tanks, which tricked oxygen sensors on the pad into reading low oxygen levels amid the leaking gas, NASA officials added.

Managers also found two small flight items near the pad that shouldn't have been there: "throat plug material" expelled from the rocket during liftoff (which happens from time to time with rocket launches), and one piece of RTV (insulating caulking) from the base of the Orion capsule.

It is unclear, however, whether the RTV flew off during launch or came off during Tropical Storm Nicole, which ripped off a strip of caulking prior to the launch; mission managers had determined before launch that the RTV issue would not be a risk.

The damage was minor enough that Sarafin characterized SLS as "a very clean system," adding that the rocket exceeded its performance targets and that the team will make some changes for Artemis 2.

Update Cubesats.

Zitat
A tiny NASA moon probe failed to perform a crucial maneuver as planned on Monday (Nov. 21), but the cubesat might still be able to salvage its water-hunting mission.

The LunaH-Map spacecraft is one of 10 cubesats that launched as ride-along payloads last Wednesday (Nov. 16) on NASA's Artemis 1 mission.

LunaH-Map was designed to map the distribution and abundance of hydrogen — and, by extension, water ice — near the moon's south pole. Such data is of great interest to NASA's Artemis program, which aims to build a crewed research outpost in this region.

The cubesat was supposed to perform an engine firing during its flyby of the moon on Monday but failed to do so, likely because of a stuck valve in its propulsion system, NASA officials said.

But all is not necessarily lost. LunaH-Map's other systems appear to be functioning normally, and heating the valve might free it, bringing the propulsion system online as well.

"If the propulsion system is able to achieve thrust within the next few months, the mission may still recover some or all of LunaH-Map's original science mission," NASA officials said in an update on Tuesday (Nov. 22). "On the spacecraft's current path, alternate trajectories are available to achieve lunar orbit — including orbits that could enable low-altitude measurements of the lunar surface."

LunaH-Map, which is led by researchers at Arizona State University, isn't the only Artemis 1 cubesat to suffer problems after being deployed by the mission's Space Launch System rocket. For example, Japan's OMOTENASHI probe experienced communications issues and failed to drop a tiny lander on the moon as a result.

NASA's Near Earth Asteroid (NEA) Scout probe has apparently been silent since the Nov. 16 launch, as has the citizen scientist cubesat Team Miles. And the LunIR spacecraft may be experiencing some trouble as well.

"Eines dieser Raumschiffe ist die Orion. Winziger Teil eines gigantischen Sicherheitssystems, das die Erde vor Bedrohungen aus dem All beschützt. Begleiten wir die Orion und ihre Besatzung bei ihrem Patrouillendienst am Rande der Unendlichkeit."

Der Chronist notiert.

Zitat von November 23, 2022 9:58 am
NASA’s Mission Control Center at the agency’s Johnson Space Center in Houston unexpectedly lost data to and from the spacecraft at 12:09 a.m. CST for 47 minutes while reconfiguring the communication link between Orion and Deep Space Network overnight. The reconfiguration has been conducted successfully several times in the last few days, and the team is investigating the cause of the loss of signal. The team resolved the issue with a reconfiguration on the ground side. Engineers are examining data from the event to help determine what happened, and the command and data handling officer will be downlinking data recorded onboard Orion during the outage to include in that assessment. There was no impact to Orion, and the spacecraft remains in a healthy configuration.

First Emirati mission to the Moon will now launch on November 30

The UAE has announced a new date for the launch of its first mission to the surface of the Moon.

The new launch date of the mission has been set to November 30 at 12.39pm local time, two days after the original date, the Mohammed bin Rashid Space Centre (MBRSC) has announced.

MBRSC had signed an agreement with Japan’s ispace in 2021, enabling the latter to provide payload delivery services to the Emirates Lunar Mission.

Upon landing, the Rashid rover will explore the characteristics of the lunar soil, the petrography and geology of the Moon, dust movement, surface plasma conditions, and the Moon’s photoelectron sheath.

Meanwhile, the integrated spacecraft will take a low-energy route to the moon rather than a direct approach, taking about five months to launch, in March 2023, according to ispace.

The mission by MBRSC plans to send a lunar rover named Rashid to the Moon in November 2022 aboard ispace's Hakuto-R lander.[3][4] The rover will land in Atlas crater.[5]

Rashid will be equipped with two high-resolution cameras, a microscopic camera to capture small details, and a thermal imaging camera. The rover will also carry a Langmuir probe, designed to study the Moon's plasma and will attempt to explain why Moon dust is so sticky.[6] The rover will study the lunar surface, mobility on the Moon’s surface and how different surfaces interact with lunar particles.[7][8]

Zitat von Artemis I – Flight Day Nine
Orion is now about one day away from entering into a distant retrograde orbit around the Moon. The orbit is “distant” in the sense that it’s at a high altitude approximately 50,000 miles from the surface of the Moon. Due to the distance, the orbit is so large that it will take the spacecraft six days to complete half of a revolution around the Moon before exiting the orbit for the return journey back to Earth.

The spacecraft completed its sixth outbound trajectory correction burn at 3:52 p.m. CST, firing the European Service Module’s auxiliary engines for 17 seconds. This is the final trajectory correction before entering distant retrograde orbit. When in lunar orbit, Orion will perform three orbital maintenance burns to keep the spacecraft on course.

Just after 1:42 p.m. CST on Nov. 24, Orion was traveling 222,993 miles from Earth and 55,819 miles from the Moon, cruising at 2,610 miles per hour.

NASA Television coverage of the distant retrograde orbit insertion burn, scheduled for 4:30 p.m. EST on Friday, Nov. 25. The burn is scheduled to take place at 4:52 p.m.

Images are sent down to Earth, and uploaded to NASA’s Johnson Space Center Flickr account and Image and Video Library. When bandwidth allows, views of the mission will be available in real-time via video stream.

Ich werd' nicht mehr. Der Kommandant des schnellen Raumkreuzers "Orion", vor 56 Jahren zum ersten Mal ins All gestartet; am 8. September 1966 (genau 9 Tage vor dem ersten Flug der NGC-1701 Enterprise unter James Tiberius Kirk) hieß bekanntlich Cliff McLane, gespielt von Dietmar Schönherr.

Cliff Allister McLane ist Major der Schnellen Raumverbände (SRV), die unter dem Kommando von General Lydia van Dyke stehen. Er ist dafür bekannt, häufiger befehlswidrig zu handeln, doch haben seine Extratouren in der Regel den Hintergrund, dass die Schreibtischhengste der Obersten Raumbehörde (ORB) allzu wenig von der praktischen Arbeit in den Weiten des Weltraums verstehen. Seine außerplanmäßigen Aktionen haben zudem zu Erfolgen geführt, die bei befehlsgemäßem Handeln mit aller Wahrscheinlichkeit nicht eingetreten wären - als da wären der Durchbruch zur Saturnbasis im Zweiten Galaktischen Krieg oder ein eigenmächtiges Eingreifen auf Alpha Centauri.

We selected an initial team of NASA astronauts – the Artemis Team – to help pave the way for the next lunar missions including sending the first woman and next man to walk on the lunar surface in 2024.

And we are not doing this alone. International partnerships are key to long-term exploration and some of their astronauts will join the Artemis Team later. Together, we will define this incredible Artemis Generation of science and lunar exploration that doesn’t stop at the Moon, rather, prepares humanity for our next giant leap, Mars.

Now, let's meet the Artemis Team!

NASA’s Lunar Flashlight SmallSat Readies for Launch
Nov. 23, 2022

Editor’s note: The Lunar Flashlight launch date has been updated to no earlier than Nov. 30.

The small satellite will search for water ice in permanently shadowed craters at the Moon’s South Pole, using an orbit only one other spacecraft has employed.

When NASA’s Lunar Flashlight launches no earlier than Nov. 30, the tiny satellite will begin a three-month journey, with mission navigators guiding the spacecraft far past the Moon. It will then be slowly pulled back by gravity from Earth and the Sun before settling into a wide science-gathering orbit to hunt for surface water ice inside dark regions on the Moon that haven’t seen sunlight in billions of years.

No larger than a briefcase, Lunar Flashlight will use a reflectometer equipped with four lasers that emit near-infrared light in wavelengths readily absorbed by surface water ice. This is the first time that multiple colored lasers will be used to seek out ice inside these dark craters. Should the lasers hit bare rock or regolith (broken rock and dust), the light will reflect back to the spacecraft. But if the target absorbs the light, that would indicate the presence of water ice. The greater the absorption, the more ice there may be.

We are bringing a literal flashlight to the Moon – shining lasers into these dark craters to look for definitive signs of water ice covering the upper layer of lunar regolith,” said Barbara Cohen, Lunar Flashlight principal investigator at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “I’m excited to see our mission contribute to our scientific understanding of where water ice is on the Moon and how it got to be there.”

The spacecraft’s orbit – called a near-rectilinear halo orbit – will take it 43,000 miles (70,000 kilometers) from the Moon at its most distant point; at its closest approach, the satellite will graze the surface of the Moon, coming within 9 miles (15 kilometers) above the lunar South Pole.

Lunar Flashlight will use a new kind of “green” propellant that is safer to transport and store than the commonly used in-space propellants such as hydrazine. In fact, Lunar Flashlight will be the first interplanetary spacecraft to use this propellant, and one of the mission’s primary goals is to test this technology for future use. The propellant was successfully tested on a previous NASA technology demonstration mission in Earth orbit.

NASA’s Green Propellant Infusion Mission Nears Completion

NASA just validated a new type of propellant, or fuel, for spacecraft of all sizes. Instead of toxic hydrazine, space missions can use a less toxic, "green" propellant and the compatible technologies designed to go along with it. In a little over a year since launch, NASA's Green Propellant Infusion Mission (GPIM) successfully proved a never-before-used propellant and propulsion system work as intended, demonstrating both are practical options for future missions.

GPIM set out to test a monopropellant – a chemical propellant that can burn by itself without a separate oxidizer – called Advanced Spacecraft Energetic Non-Toxic (ASCENT). Formerly known as AF-M315E, the U.S. Air Force Research Laboratory invented the propellant at Edwards Air Force Base in California. It is an alternative to the monopropellant hydrazine.

“This is the first time in 50 years NASA tested a new, high-performing monopropellant in space,” said Tim Smith, GPIM mission manager at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “It has the potential to supplement or even replace hydrazine, which spacecraft have used since the 1960s.” Based at Marshall, NASA’s Technology Demonstration Mission (TDM) program manages the mission.

GPIM’s effective demonstration of the propellant paved the way for NASA’s acceptance of ASCENT in new missions. The next NASA mission to use ASCENT will be Lunar Flashlight. The small spacecraft, which aims to provide clear-cut information about the presence of water deposits inside craters on the Moon, will launch as a secondary payload on Artemis I, the first integrated flight test of NASA's Orion spacecraft and Space Launch System (SLS) rocket.

Despite being pink in color, ASCENT is considered “green” for its significantly reduced toxicity compared to hydrazine, which requires protective suits and rigorous propellant loading processing procedures. It is safer to store and use, requiring minimal personal protective equipment such as lab coats, goggles, and gloves. Besides being easier and less expensive to handle here on Earth, when loading a spacecraft with propellant, for example, ASCENT will allow spacecraft to travel farther or operate longer with less propellant in their tank, given its higher performance.

South Korean leader eyes “landing on moon in 2032, Mars in 2045” - by Park Si-soo — November 29, 2022

SEOUL, South Korea — President Yoon Suk-yeol of South Korea said Nov. 28 that the country will land a robotic spacecraft on the moon in 2032 and on Mars in 2045, when the nation will mark the 100th anniversary of liberation from 35 years of Japanese colonial rule.

This was part of a set of broader space exploration goals the president unveiled during a keynote speech at the Korea Space Forum 2022 here. To reach the ambitious goals, he promised to double the government’s space development budget in the next five years and funnel at least 100 trillion won ($74.7 billion) into the space sector by 2045. South Korea’s space budget for 2022 is 734 billion won ($553 million).
...
Yoon didn’t elaborate on the next-generation engine, which he said will be developed in five years. A science ministry official managing the engine development was not immediately available for comment. The kerosene and liquid oxygen-fueled KRE-075 engine, used to launch South Korea’s first homegrown space rocket KSLV-2, is the most advanced rocket engine the country has developed. And the Korea Aerospace Research Institute (KARI) started developing liquid-fueled 100-ton thrust engines this year for future missions.

The president didn’t explain why the target year for moon landing was pushed back to 2032 from 2030, set by his predecessor. Chang Dong-soo, a science ministry official involved in the moon landing project, told SpaceNews that the longer-than-expected time to develop a lander and a carrier rocket could be blamed for the delay.

Landing on Mars is a new objective for South Korea. Details are expected to be included in the 4th revision of the Basic Plan for Promotion of Space Development, a five-year plan that covers through 2027.

“By 2045, we will be able to plant our national flag on Mars,” Yoon said. “To make this happen, we will develop unimaginable technologies and explore uncharted areas.”

Nov 29, 2022 RELEASE 22-124 "NASA, ICON Advance Lunar Construction Technology for Moon Missions"

NASA has awarded ICON, located in Austin, a contract to develop construction technologies that could help build infrastructure such as landing pads, habitats, and roads on the lunar surface.

"In order to explore other worlds, we need innovative new technologies adapted to those environments and our exploration needs," said Niki Werkheiser, director of technology maturation in NASA's Space Technology Mission Directorate (STMD). "Pushing this development forward with our commercial partners will create the capabilities we need for future missions."

The award is a continuation of ICON's work under a Small Business Innovation Research (SBIR) dual-use contract with the U.S. Air Force, partly funded by NASA. The new NASA SBIR Phase III award will support the development of ICON's Olympus construction system, which is designed to use local resources on the Moon and Mars as building materials. The contract runs through 2028 and has a value of $57.2 million.

ICON will work with NASA’s Marshall Space Flight Center in Huntsville, Alabama, under STMD’s Moon to Mars Planetary Autonomous Construction Technologies (MMPACT) project. NASA is partnering with industry, government, and academic institutions under the MMPACT project.

The award will build on ICON’s commercial activities and other work with NASA.

ICON 3D printed a 1,700-square-foot simulated Martian habitat, called Mars Dune Alpha, that will be used during NASA's Crew Health and Performance Analog, or CHAPEA, analog mission starting in 2023.

ICON also competed in NASA's 3D Printed Habitat Challenge. The company partnered with the Colorado School of Mines in Golden, and the team won a prize for 3D printing a structure sample that was tested for its ability to hold a seal, for strength, and for durability in temperature extremes.
