Welcome to Astronomy Daily, your daily dose of space and astronomy news. I'm

your host Anna. In today's episode, we'll cover the latest updates about the

Hubble Space Telescope and how it's shifting into one gyroscope mode. We'll also delve

into SpaceX's recent milestones, including the Starlink eight five satellite launch and the FAA's

approval for Starship Flight four. Plus, we'll highlight several other noteworthy events happening

in the ever evolving realm of space exploration. Thank you for joining us.

Thanks Autonomy Daly Podcast. The Hubble Space Telescope has once again shown signs of

aging, requiring a shift into what's known as one gyroscope mode. This transition

was necessitated by a malfunction in one of the gyroscopes responsible for maintaining Hubble's precise

orientation towards its celestial targets. NASA officials have explained that the telescope, which

originally housed six gyros, now has only two operational ones, with an announcement

today confirming the transition to utilizing just one of them. The remaining functional gyro

will be kept in reserve for future use. Despite this adjustment. NASA has

assured us that this does not mark the end of Hubble's illustrious career. There

is confidence that Hubble will continue its groundbreaking work well into the next decade.

Mark Lampin, director of NASA's Astrophysics Division, underlined that this strategy is the

best approach to extend Hubble's operational life. The shift to one gyro mode will

have minimal impact on the majority of its observations. Hubble's pointing control system typically

utilizes three gyros, but it has demonstrated effective operation in two gyro mode in

the past, making one gyro mode a viable long term option. This change

does come with some operational limitations. For example, transitioning from one science target

to another will take slightly longer, and there will be a reduction in scheduling

efficiency approximately twelve percent, according to Hubble project manager Patrick Krauss. Additionally,

Hubble will have less flexibility in its observational scope and will be unable to track

moving targets closer than Mars, though such targets have historically been rare. Looking

ahead, the telescope is expected to resume its work in mid June under the

new operational configuration. NASA's updated reliability assessments suggest a high probability of at least

one gyro remaining functional through twenty thirty five, which should ensure that Hubble continues

to illuminate our understanding of the universe for years to come. So, while

Hubble may have lost a bit of its precision, its ability to offer groundbreaking

insights into the Cosmos remains largely intact. The Telescope's storied history of servicing missions

and technological upgrades gives hope that it will continue to contribute valuable scientific data,

reinforcing its legacy as one of the most important observatories in astronomical history. Stay

tuned to Astronomy Daily for more updates on Hubble and other exciting space missions.

Now, let's turn our attention to SpaceX and their latest achievement. SpaceX recently

completed the Starlink eight five mission, adding another success to their remarkable track record.

This mission saw the Falcon nine rocket lift off from Pad forty at Cape

Canaveral Space Force Station, deploying twenty Starlink V two mini satellites. Among these,

thirteen satellites notably featured direct to cell phone capabilities, a significant advancement for

global communication. The Falcon nine's first stage booster, known in the SpaceX fleet

as B one thousand sixty seven, reached its twentieth flight during this mission,

a testament to SpaceX's pioneering advancements in rocket reusability. This particular booster had a

storied past, having supported two crew Dragon astronaut missions, two cargo Dragon resupply

missions to the International Space Station, and ten prior Starlink delivery runs. After

its latest feat, B one thousand sixty seven successfully landed on the drone ship

read the instructions stationed in the Atlantic Ocean. This marked the eighty third landing

for the specific drone ship and the three hundred and sixteenth overall booster landing for

SpaceX. SpaceX founder Elon Musk recently highlighted the achievements of the Starlink network,

revealing a new internal median latency record of twenty eight milliseconds for their Internet service.

Musk further noted that the median latency for Starlink Internet in the United States

could soon dip below twenty milliseconds, a promising development for users. This launch

not only underscores SpaceX's capability to execute frequent and precise missions, but also moves

them closer to their goal of providing widespread, high speed Internet access. With

each successful mission, SpaceX continues to redefine the parameters of spaceflight and satellite communications.

In other SpaceX news, their ambitious plans for interplanetary travel took another significant

step forward as the FAA recently granted approof for Starship Flight four, scheduled to

lift off from the Starbase facility in South Texas. This mission is crucial for

testing the capabilities of both the Starship and its super heavy booster. These tests

are aimed at ultimately fulfilling SpaceX's longer term goals of lunar and martian missions.

The FAA's approval comes with a license that includes certain test induced damage scenarios.

This means that the agency has identified specific conditions under which vehicle loss would not

delay subsequent missions, expediting the test and evaluation process. By outlining these scenarios

ahead of time, SpaceX and the FAA can focus on streamlining the steps necessary

to safely and efficiently move forward with future flights. Starship and its super heavy

booster are pivotal components of SpaceX's vision standing nearly four hundred feet tall, they

represent the most powerful rocket ever built to date. The company has tested Starship

on three previous flights, all of which have provided key data, bite not

achieving complete mission success, each test has been a learning opportunity, improving the

design and operational procedures of the rocket system. This fourth flight aims to achieve

high orbital velocity, followed by intricate re entry and splash down maneuvers. SpaceX's

focus this time is not only on reaching orbital speed, but also on demonstrating

reusability features core to making future missions to the Moon and Mars economically viable.

The super heavy booster will attempt a controlled splash down into the Gulf of Mexico,

while the Starship vehicle will aim for re entry over the Indian Ocean.

As SpaceX progresses, the importance of efficient regulatory processes and robust testing frameworks cannot

be overstated. The collaborative approach between SpaceX and the FAA in modifying the launch

license to include pre approved damage scenarios is a testament to this. It reflects

a mutual commitment to advancing space exploration while maintaining stringent safety protocols. The aerospace

community and space enthusiasts alike will be keenly watching Starship Flight four, anticipating its

contributions to the future of human spaceflight and the new frontier it aims to open.

This mission is more than a test flight. It is a significant milestone

toward realizing the dream of making space travel more accessible and sustainable. NASA,

Boeing and United Launch Alliance are gearing up for a third attempt to launch the

Boeing Starliner on its inaugural crude flight. This follows previous setbacks due to a

failed power distribution source and issues with the launch vehicle. United Launch Alliance engineers

have since rectified the electrical problem, and mission management has given the green light

for a launch attempt on June fifth. The crew for this mission, astronauts

Butch Wilmore and Sunny Williams, are set to embark on a journey to the

International Space Station. Isss a significant milestone in Boeing's efforts to provide NASA with

reliable crew transportation capabilities under the Commercial Crew Program. The launch window is precisely

timed, with liftoff scheduled for ten fifty two am EDT aiming to align the

spacecraft's trajectory with the orbit of the ISS. If successful, the Starliner will

dock with the ISS approximately twenty four hours after launch. This mission will not

only transport the two astronauts, but also a variety of scientific experiments and supplies.

The teams stay on the ISS will allow them to conduct essential research and

collaborate with current crew members before their planned return to Earth, landing in White

Sands, New Mexico on June fourteenth. This endeavor follows a series of delays

and adjustments, including a scrapped launch attempt in early May due to technical issues.

Despite these challenges, the teams at NASA, Boeing and ULA have worked

tirelessly to resolve the problems to ensure the mission's success. As we approach the

launch time, weather forecasts indicate a ninety percent chance of favorable conditions, with

only some cumulus clouds posing a potential concern. In addition, solar activity,

which has been elevated recently, will be monitored closely to ensure safe flight conditions.

The upcoming mission represents a crucial step towards certifying the Starliner for regular crew

rotation missions to the ISS, potentially beginning as soon as spring twenty twenty five.

This achievement will mark a significant advancement in NASA's goal of having multiple domestic

providers for transporting astronauts to space, enhancing the robustness and capabilities of human spaceflight

operations. Russian cosmonaut Oleg Kononenko has etched his name into the annals of space

history by becoming the first person to reach an astounding one thousand cumulative days in

space. This extraordinary milestone was reached during his fifth mission aboard the International Space

Station ISS, where he is currently serving as commander. Kononenko, who launched

on the Soyuz MS twenty four spacecraft last September, has not only demonstrated the

incredible human capability to an endure long term space missions, but also provided scientists

with a unique opportunity to study the effects of prolonged exposure to the space environment.

Renowned aerospace medicine expert Immanual Urkieta underscores the significance of Cononenko's achievement. According

to Urkieta, this milestone allows researchers to gather invaluable data on the physiological and

psychological impacts of long duration space flights. Key areas of study include radiation exposure,

bone density loss, muscle atrophy, and mental well being in isolated and

confined environments. Such research is crucial for planning future missions to the Moon,

Mars, and beyond. As humanity prepares for longer and more distant space expeditions,

the data collected from Cononenko's time and space will be instrumental. It helps

establish a clearer understanding of what astronauts will face on missions that could span several

years. Moreover, this knowledge could lead to advancements in medical treatments and health

monitoring technologies that benefit not only future space travelers, but also those on Earth,

especially in remote or medically underserved areas. So as we celebrate Conenenko's remarkable

journey, we also look forward to the scientific advancements his experience will bring,

paving the way for humanity's next giant leap. Stay tuned for more updates as

we continue to explore the frontiers of space. A recent solar storm gifted us

with an awe inspiring display of auroras lighting up the skies with vibrant curtains of

pink and green. This dazzling spectacle marks the beginning of what promises to be

a particularly active period for our sun as it nears the peak of its eleven
