quote:Watch the launch from New Zealand of CAPSTONE, a new pathfinder CubeSat that will explore a unique orbit around the Moon!
The Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment, or CAPSTONE, will be the first spacecraft to fly a near rectilinear halo orbit (NRHO) around the Moon, where the pull of gravity from Earth and the Moon interact to allow for a nearly-stable orbit. CAPSTONE's test of this orbit will lead the way for our future Artemis lunar outpost called Gateway.
CAPSTONE is targeted to launch at 5:55 a.m. EDT (9:55 UTC) Tuesday, June 28 on Rocket Lab’s Electron rocket from the company’s Launch Complex 1 in New Zealand.
Launch is currently slated to take place no earlier than August 29, 2022quote:

Artemis I managers conduct a Flight Readiness Review (FRR) on Aug. 22, 2022, at NASA’s Kennedy Space Center in Florida. The FRR is an in-depth assessment of the readiness of the agency’s Space Launch System and Orion spacecraft to support the uncrewed flight of Artemis I on its mission beyond the Moon and return to Earth. The meeting will conclude later in the day with a poll of all managers. Artemis I is scheduled to launch at 8:33 a.m. EDT on Aug. 29, 2022, from Kennedy’s Launch Complex 39B. The first in a series of increasingly complex missions, Artemis I will provide a foundation for human deep space exploration and demonstrate our commitment and capability to extend human presence to the Moon and beyond. The primary goal of Artemis I is to thoroughly test the integrated systems before crewed missions by operating the spacecraft in a deep space environment, testing Orion’s heat shield, and recovering the crew module after reentry, descent, and splashdown.
The Flight Readiness Review for NASA’s Artemis I mission has concluded, and teams are proceeding toward a two-hour launch window that opens at 8:33 a.m. EDT Monday, August 29, from Kennedy Space Center’s Launch Pad 39B in Florida. NASA will hold a media conference at approximately 8 p.m. to discuss the outcome of the review. Listen live on the agency’s website.

Een straalmotor zuigt lucht op uit de blote buitenlucht. Daar zit 20% zuurstof in. De rest is voornamelijk stikstof en doet weinig met de brandstof. Maar het is wel allemaal propellant!

Een raketmotor is (net als een straalmotor) een reactie-motor. De raket gaat de ene kant op omdat de motor massa de andere kant op jaagt. Die massa zit in propellant (drijfstof). Drijfstof is alles wat de raketmotor in gaat en er heet en hard weer uitkomt. Propellant is dus je brandstof, maar ook je zuurstof. Sterker nog: zuurstof is veel zwaarder dan brandstof. Zuurstof is 80% van je propellant.
Er zijn mensen die denken dat een raket zijn eigen zuurstof mee moet nemen om de brandstof te verbranden, maar eigenlijk is het andersom. Je neemt brandstof mee om de zuurstof te verwarmen, want de zuurstof is je voornaamste propellant.

https://www.theverge.com/(...)ight-launch-nasa-slsquote:NASA has confirmed its next launch attempt for the Artemis I mission will be at night, with a midnight launch scheduled for the early hours of Monday, November 14th. Following a difficult few months attempting to get the Space Launch System rocket off the ground for the first time, including several wet dress rehearsals, two previous launch attempts, a tanking test, and an interruption from a hurricane, the rocket will begin rolling back out to Launch Pad 39B at Kennedy Space Center in Florida just after midnight on Friday, November 4th.
A night launch means lower visibility, and NASA representatives said they would have preferred a daylight launch. However, the team was confident that a night launch could be done safely and meet all the mission requirements, said Jim Free, associate administrator at NASA’s Exploration Systems Development Mission Directorate. As for the public audience, the night launch means the view won’t be as good, but there should still be some visuals available.

Hopelijk is het niet te ernstig, hoewel een lek altijd ernstig klinktquote:NASA fuelled up the Artemis 2 mission's Space Launch System (SLS) rocket on Monday (February 2) as part of a crucial test before Orion lifts off for the Moon. The space agency mission loaded the Space Launch System (SLS) rocket with more than 700,000 gallons (2.65 million litres) of cryogenic liquid hydrogen (LH2) and liquid oxygen (LOX) on Pad 39B at Kennedy Space Center (KSC) in Florida. Artemis 2 is scheduled to lift off not before February 8. However, the test showed a leak. Can this push the launch date forward? The good news is that even though the teams had to stop loading LH2 into the SLS core stage twice to deal with leaks, they were able to fix the problem immediately. The fuelling test ran over two days, starting January 31 and ending with the fuelling of the rocket. The wet dress rehearsal won't be over till 1 am EST, as all the loaded-up fuel will then be drained out. NASA hasn't officially called the test a success, as the test is still going on. It will hold a press conference at 12 pm EST on Tuesday (February 3) and reveal the details of the fuelling test.
quote:NASA said Tuesday it was delaying its mission to send four astronauts on a journey around the moon, after issues arose during a critical test of its enormous rocket.
Mission managers were conducting an elaborate launch day walkthrough, known as a “wet dress rehearsal,” at Kennedy Space Center in Florida when engineers detected leaking hydrogen at the base of the Space Launch System rocket. NASA was forced to end the test a little after midnight ET, with around 5 minutes and 15 seconds remaining in the simulated launch countdown.
Shortly after 2 a.m. ET on Tuesday, NASA announced it would forgo February’s launch window for the Artemis II mission around the moon, which extended from Friday through Feb. 11, to allow teams to review data and conduct another wet dress rehearsal. It said it will now aim for March “as the earliest possible launch opportunity.”
The space agency has said there are available launch opportunities from March 6 through March 9, and on March 11, with additional dates in April, if needed.
NASA’s wet dress rehearsal was essentially an elaborate launch day walkthrough that allowed mission managers to assess the performance and readiness of the rocket. Officials are expected to discuss early results from the test in a briefing on Tuesday at 12 p.m. ET.
“With more than three years between SLS launches, we fully anticipated encountering challenges,” NASA Administrator Jared Isaacman wrote in a post on X. “That is precisely why we conduct a wet dress rehearsal. These tests are designed to surface issues before flight and set up launch day with the highest probability of success.”
The hourslong rehearsal involved filling the Space Launch System rocket with more than 700,000 gallons of cryogenic propellant and simulating each step of the launch countdown as would occur on the actual day.
During the fueling process, which got underway at around 12:30 p.m. ET on Monday, mission managers twice paused proceedings to investigate leaking hydrogen fuel at the tail end of the rocket.
Despite eventually pressing on and conducting tests of the Orion spacecraft, which sits atop the rocket, the hydrogen leaks cropped up again in the final minutes of the simulated launch countdown.
NASA said that systems aboard the rocket that are designed to take over control of the booster in the final minutes before liftoff “automatically stopped the countdown due to a spike in the liquid hydrogen leak rate.”
Additionally, engineers will investigate several audio issues in communications channels used by ground teams that occurred during the wet dress rehearsal.
The four astronauts who were set to fly on the Artemis II flight — NASA astronauts Reid Wiseman, Christina Koch and Victor Glover and Canadian astronaut Jeremy Hansen — were set to arrive at Kennedy Space Center Tuesday afternoon. They had been in quarantine in Houston since Jan. 21 to protect against preflight exposure to germs.
But NASA said the astronauts will now be released from quarantine and will not travel to Florida as planned.
Instead, the crew will enter quarantine again roughly two weeks before the next targeted launch opportunity, according to the agency.
Artemis II will be the second trip to space for NASA’s Space Launch System rocket and Orion capsule, but the first time they carry humans.
The much-anticipated launch is expected to represent a crucial step toward realizing NASA’s goal of returning astronauts to the lunar surface.
A previous uncrewed Artemis I flight around the moon in 2022 was delayed six months because of hydrogen leaks identified during its first wet dress rehearsal.
With humans set to fly aboard the Space Launch System rocket and Orion capsule for the first time, the stakes for the Artemis II flight are high.
“As always, safety remains our top priority, for our astronauts, our workforce, our systems, and the public,” Isaacman said on X, adding that NASA “will only launch when we believe we are ready to undertake this historic mission.”
quote:Engineers ran into problems repressurizing the Artemis 2 moon rocket’s upper stage helium tanks overnight Friday, a problem that will require rolling the huge rocket off the launch pad and back to its processing hangar for troubleshooting. The work will push the already delayed mission from March to at least early April, officials said Saturday.
Pressurized helium is used to push propellants to rocket engines for ignition and to purge various fuel lines to clear them out before propellants flow. It’s not yet known what might be preventing helium to flow back into the SLS rocket’s upper stage following a successful countdown rehearsal test that ended Thursday.
“Regardless of the potential fault, accessing and remediating any of these issues can only be performed in the VAB (Vehicle Assembly Building),” NASA Administrator Jared Isaacman said in a post on the social media platform X. “We will begin preparations for rollback, and this will take the March launch window out of consideration.”
The Artemis 2 mission aims to send four astronauts – Reid Wiseman, Victor Glover, Christina Koch and Canadian astronaut Jeremy Hansen – on a flight around the far side of the moon and back to thoroughly test the agency’s Orion deep space capsule to help clear the way for a lunar landing mission, Artemis 3, in 2028.
Because of the ever-changing positions of the Earth and moon, and associated changes in lighting and other factors, only a handful of launch opportunities are available each month that meet the Artemis 2 mission requirements. The current launch period ends on March 11. The available launch dates next month are April 1, 3, 4, 5 and 6.
Wiseman, Glover, Koch and Hansen originally hoped to launch early this month, but hydrogen leaks detected during an initial “wet dress countdown” rehearsal ultimately pushed the flight to March.
NASA completed a second fueling test and countdown Thursday, loading the Space Launch System rocket with more than 750,000 gallons of liquid oxygen and hydrogen fuel while working through the steps that will be needed to actually launch the huge rocket on the long-awaited mission.
The test went well, there were no fuel leaks like the ones that derailed plans for a launch earlier this month. Managers said Friday the team would press ahead for a launch attempt on March 6 to send Wiseman and his crewmates to the moon.
Hoping for the best, the astronauts went into pre-flight medical quarantine at the Johnson Space Center Friday evening and planned to fly to the Kennedy Space Center on March 1 to prepare for launch. They now will leave quarantine to await developments.
“I understand people are disappointed by this development,” Isaacman said. “That disappointment is felt most by the team at NASA, who have been working tirelessly to prepare for this great endeavor. During the 1960s, when NASA achieved what most thought was impossible, and what has never been repeated since, there were many setbacks.
“There are many differences between the 1960s and today, and expectations should rightfully be high after the time and expense invested in this program.
“I will say again, the President created Artemis as a program that will far surpass what America achieved during Apollo. We will return in the years ahead, we will build a Moon base, and undertake what should be continuous missions to and from the lunar environment. Where we begin with this architecture and flight rate is not where it will end

mission as agency grapples with delays and glitches
Nasa announces Artemis III mission no longer aims to send humans to moon
Plans to return humans to the moon will come in later mission as agency grapples with delays and glitches
Ed Pilkington
Fri 27 Feb 2026 19.16 CET
Nasa announced on Friday radical changes to its delayed Artemis III mission to land humans back on the moon, as the US space agency grapples with technical glitches and criticism that it is trying to do too much too soon.
The abrupt shift in strategy was laid out by the space agency’s recently confirmed administrator, Jared Isaacman. Announcing the changes on Friday, he said that Nasa would introduce at least one new moon flight before attempting to put humans back on the lunar surface for the first time in more than half a century, in 2028.
The new, more incremental approach would give the Nasa team a chance to test flight and refine its technology. As part of the changes, the Artemis II mission to fly humans around the moon this year, without landing, would also be pushed back from its latest scheduled launch on 6 March to 1 April at the earliest.
“Everybody agrees this is the only way forward,” Isaacman told reporters at a news conference. “I know this is how Nasa changed the world, and this is how Nasa is going to do it again.”
The revised course came as Nasa has been wrestling with a number of delays and technical problems. Earlier this week, the independent body that reviews space safety issued a blunt report sharply criticising the space agency’s current plans as too risky.
The aerospace safety advisory panel recommended that Nasa rethink its objectives for Artemis III, which had been conceived as the first human landing on the moon since the final flight in the Apollo series in December 1972. The panel said that the call for a revision was urgent, “given the demanding mission goals”.
Isaacman said that under the new plan, the eventual moon landing would be achieved through evolutionary steps rather than big leaps in technological procedures. “We’re going to get there in steps, continue to take down risk as we learn more and we roll that information into subsequent designs,” he told CBS News.
He added: “We’ve got to get back to basics.”
Step one in the revised schedule is the launch of the Artemis II moon mission, which has been plagued by delays. The rocket was returned to its hangar at the Kennedy Space Center in Florida earlier this week.
Engineers had discovered a blockage in the rocket’s helium flow in the upper stage of the booster.
The latest delay followed disappointment in February, when Nasa was forced to put off the launch of Artemis II after hydrogen was found leaking from its Space Launch System rocket.
Artemis II will send four astronauts on a 10-day journey around the moon, designed to take people further into space than ever before, beyond the record set by Apollo 13 in 1970.
Isaacman said on Friday that additional missions would then be included in the schedule. He likened the extra steps to the approach taken in Nasa’s original moon landing in which Neil Armstrong and Buzz Aldrin first stepped on to the lunar surface in 20 July 1969.
That legendary event was hazarded only after three separate moon missions had been completed.
The Artemis III mission will no longer aim to land on the moon. Instead, under the revised plans, it will be launched by mid-2027 as a low-Earth orbit designed to test essential technologies.
That extra stage is intended to give Nasa extra flight experience with the massively complex advanced systems and the chance to test its space vehicles before it attempts a human moon landing. Should all that go to plan, then a new Artemis IV mission would set out in 2028 to land on the moon.
The eventual aspiration is to land astronauts near the moon’s south pole. A second moon landing, Artemis V, could be conducted in 2028, followed by a moonshot attempted each year thereafter, Nasa said.

NASA’s website (www.nasa.gov/trackartemis)quote:As NASA invites the public to follow the Artemis II mission as a crew of four astronauts venture around the Moon inside the agency's Orion spacecraft, people around the world can pinpoint Orion during its journey using the Artemis Real-time Orbit Website (AROW).
During the approximately 10-day mission, NASA will test how the spacecraft's systems operate as designed with crew aboard in the deep space environment. Using AROW, anyone with internet access can track where Orion and the crew are, including their distance from Earth, distance from the Moon, mission duration, and more. Access to AROW is available on:
quote:Using AROW, the public can visualize data that is collected by sensors on Orion and then sent to the Mission Control Center at NASA's Johnson Space Center in Houston during its flight. It will provide constant information using this real-time data beginning about one minute after liftoff through Orion's atmospheric reentry to Earth at the end of the mission.
Online, users can follow AROW to see where Orion and the crew are in relation to the Earth and the Moon and follow Orion's path during the mission. Users can view key mission milestones and characteristics on the Moon, including information about landing sites from the Apollo program.
The mobile app includes similar features to the website, with the addition of augmented reality tracker. After a brief calibration sequence, on-screen indicators will direct users where to move their phone to see where Orion currently is relative to their position on Earth. Mobile app tracking will be available once Orion separates from the rocket's upper stage, approximately three hours into the mission.
State vectors, or data that describes precisely where Orion is located and how it moves, also will be provided by AROW, following a proximity operations demonstration to evaluate the manual handling qualities of Orion.
These vectors can be used for data lovers, artists, and creatives to make their own tracking app or data visualization. Also available for download will be trajectory data from the flight, called an ephemeris, found at the bottom of this page, after the mission begins. The ephemeris data can be used to track Orion with your own spaceflight software application or telescope, or to create projects such as a physics model, animation, visualization, or tracking application.
Artemis II, the agency's first crewed mission in the Artemis campaign, is a key step in NASA's path toward establishing a long-term presence at the Moon and confirming the systems needed to support future lunar surface exploration and paving the way for the first crewed mission to Mars.
