NASA launched the most powerful rocket ever built on a journey to the Moon on Wednesday, in a spectacular blaze of light and sound that marked the start of the space agency’s new flagship program, Artemis. The 32-story tall Space Launch System (SLS) blasted off from the storied Kennedy Space Center in Florida at 01:47 am (12:17pm IST).

“We are going,” tweeted the space agency.

Fixed to its top was the uncrewed Orion spaceship that will later separate and complete an orbit-and-a-half of Earth’s nearest neighbor, in a test run for later flights that should see the first woman and first person of color touch down on lunar soil by the mid-2020s.

America last sent astronauts to the Moon during the Apollo era, from 1969-1972. This time it hopes to build a sustained presence — including a lunar space station — to help prepare for an eventual mission to Mars.

The launch came despite technical issues that ate into the two-hour launch window that opened at 1:04 am (11:34am IST).

Engineers were forced to pause the flow of liquid hydrogen into the core stage Tuesday night because of a valve leak, though a team sent to the launch pad resolved the problem after an hour.

Later, the space agency reported that a radar site monitoring the rocket’s flight path was experiencing problems due to a faulty ethernet switch that had to be replaced.

It was third time lucky for NASA after two previous launch attempts were canceled for technical reasons. Launch was also delayed due to weather setbacks, including Hurricane Ian that battered Florida in late September.

‘Extremely excited’

About 100,000 people were expected on the coast to watch the launch, with the rocket promising to light up the night sky.

Andrew Trombley, a space enthusiast from St. Louis, Missouri, was anxiously hoping for a successful liftoff after several futile trips made for the launch.

“I’ve been down here a couple of times already to watch this thing go up and have it canceled, so, this is like, whatever, the third trip down here for this, so I’m excited to see it go,” said the network engineer.

“I was too little for the Apollo missions, so … I wanted to be here in person.”

Kerry Warner, 59, a grandmother and semi-retired educator who lives in Florida, was fired up for liftoff, which she said was “part of America and what America is all about.”

“Third time’s the charm. We’re hoping for it.”

Far side of Moon

The Orion crew capsule was being lifted by two boosters and four powerful engines under the core stage, which detached after only a few minutes.

After a final push from the upper stage, the capsule will be well on its way, taking several days to reach its destination.

Rather than landing on the Moon, it will assume a distant orbit, venturing 40,000 miles (64,000 kilometers) beyond the far side — further than any other habitable spacecraft so far.

Finally, Orion will embark on the return leg of its journey. When passing through the atmosphere, the capsule’s heat shield will need to withstand a temperature half as hot as the Sun’s surface.

The mission will last 25 and a half days, with a splashdown in the Pacific Ocean on December 11.

NASA is banking on a successful mission after developing the SLS rocket for more than a decade. It will have invested more than $90 billion in its new lunar program by the end of 2025, according to a public audit.

Artemis 2 will involve a flyby of the Moon with astronauts in 2024, while Artemis 3 will see boots on lunar soil, no sooner than 2025.

NASA has named its Moon mission after the Greek goddess of the hunt, and the program aims to send humans back to the Moon by 2025. The last time astronauts walked the surface of the Moon was in 1972, as part of NASA’s Apollo mission. The Artemis mission eventually plans to set up a base for astronauts on the Moon, ahead of long-term plans to send humans to Mars.

Massive Steam Plume Spotted at Alaska’s Mount Spurr as Volcano May Erupt Soon

A large steam plume has been seen emerging from Mount Spurr in Alaska, signalling increased volcanic activity. Images shared by the Alaska Volcano Observatory (AVO) on March 28 confirmed steam and gas emissions visible from the volcano’s summit and a northern vent. The volcano is located around 80 miles west of Anchorage and stands at 11,070 feet high. The experts have revealed that there could be a possible eruption in the coming weeks or months. However, nothing is certain yet.

Increased Signs of Unrest Reported

According to the latest update by the Alaska Volcano Observatory steam was observed rising from the summit on March 26. A smaller plume was also recorded from a fumarole on the volcano’s northern flank. No immediate changes in seismic activity or gas levels were detected during these observations as per the AVO statement.

The AVO had earlier mentioned in a March 11 update that a noticeable rise in gas emissions indicates fresh magma has moved into the crust beneath Mount Spurr. This has led scientists to assess the chance of an eruption in the near future. The observatory clarified that the exact timing of any eruption cannot be predicted yet.

Hazards and Possible Alerts

The observatory has cautioned that the volcano’s alert level might be raised if there are further signs of escalation. According to AVO, this may include persistent seismic tremors, increased gas emissions or visible surface changes. If an eruption occurs, possible hazards include ash clouds impacting flights, ashfall across nearby areas, pyroclastic flows and mudflows known as lahars.

The volcano last erupted in 1992. That eruption resulted in heavy ashfall and affected air travel in the region. AVO has advised residents and visitors to stay informed and follow safety instructions if alerts are raised.

Study Identifies Plasma Formation as a Pseudostreamer

A towering spiral of plasma has been recorded extending millions of kilometres from the Sun. The video was taken by the European Space Agency’s Solar Orbiter during an eight-hour period on October 12, 2022. A coronal mass ejection caused the plasma to rise from the Sun’s surface. The footage captured something which was never observed before. It showed a swirling motion in the solar wind. As per the latest report, scientists also recorded bright streaks that were moving across the frame. Researchers also revealed that these streaks appeared as pixelated lines, which might also ressemble like UFOs. Scientists later confirmed they were distant stars visible due to the imaging process.

Study Identifies Plasma Formation as a Pseudostreamer

The study published in The Astrophysical Journal revealed that the massive structure that appeared in the photos was a large pseudostreamer. It was formed near the Sun’s north pole after a solar flare erupted. The report further highlighted that the plasma reached 1.5 times the Sun’s width and remained visible for three hours. Scientists believes the twisting movement of the plasma was due to Alfvénic fluctuations. These fluctuations happen when waves of charged particles respond to magnetic disturbances. Scientists says the pseudostreamer’s location influenced its unique shape. Magnetic fields at the Sun’s poles are stronger than those near the equator.

Unusual Streaks Explained

The video also showed bright, half-dark lines crossing the screen. These lines appeared to move in a pattern similar to arcade game graphics. ESA confirmed that these were distant stars. The video’s editing technique made them appear as streaks rather than points of light. The Solar Orbiter’s movement against the background created this effect.

Solar Activity Expected to Intensify

The Sun is currently experiencing solar maximum. Flares and solar winds have increased since early 2024. The pseudostreamer in the video formed before this peak. Scientists were surprised by its early appearance. ESA’s Solar Orbiter continues to capture detailed images of solar wind. NASA’s Parker Solar Probe and ESA’s Proba-3 mission are also studying these phenomena. More extreme solar winds are expected in the coming years.

SpaceX Launches 27 Starlink Satellites on Falcon 9 Rocket, Booster Lands Safely

SpaceX has sent another batch of satellites into orbit. On April 3, a Falcon 9 rocket launched 27 Starlink satellites from Vandenberg Space Force Base in California. The rocket lifted off at 9.02 p.m. Eastern Time and was followed by a successful landing of the first-stage booster on a drone ship stationed in the Pacific Ocean. This booster had already been used on four earlier flights. The satellites are expected to be deployed nearly an hour after takeoff if mission steps proceed as planned. The launch formed part of SpaceX’s continued effort to expand its low Earth orbit network.

Details from the Launch Mission Description

According to the mission information provided by SpaceX, the launch marked the fifth use of the same Falcon 9 booster. The drone ship used for recovery was named “Of Course I Still Love You”. This reusable system has become a routine part of SpaceX operations. The booster’s return was completed around eight minutes after liftoff. The launch contributed to the growing total of Starlink satellites which is aimed at building a global broadband network.

Launch Activity in 2025

This latest mission has brought the number of Falcon 9 launches in 2025 to 38. About two-thirds of those have supported the expansion of the Starlink constellation. Earlier this week, two separate launches were also completed. One of them included the Fram2 private astronaut mission, which carried crew members into orbit over Earth’s poles. That mission marked a new milestone in human spaceflight.

Starlink Satellite Network

Over 7100 satellites are now part of the Starlink constellation. The system is already the largest of its kind. SpaceX continues to work on expanding its coverage by launching more satellites regularly. The objective remains to provide consistent internet access worldwide, especially in regions with limited connectivity options.
