A new spacecraft is set to launch on a journey to the Sun. It’s goal: to snap the first pictures of the Sun’s north and south poles.

Dubbed Solar Orbiter, the spacecraft is a collaboration between the European Space Agency (ESA) and NASA. The 3,970-lb. (1,320 kg) spacecraft will launch atop United Launch Alliance (ULA) Atlas V rocket on Feb. 7, 2020, during a two-hour launch window that opens at 11:15 p.m. EST (0415 GMT Feb. 8).

It’s launching at night because the spacecraft is on a path to Venus where it will use the planet’s gravity to slingshot itself out of the ecliptic plane — the area of space where all planets orbit.

From that vantage point, Solar Orbiter’s on-board cameras will capture the first-ever view of the Sun’s poles.

“Up until Solar Orbiter, all solar imaging instruments have been within the ecliptic plane or very close to it,” Russell Howard, space scientist at the Naval Research Lab in Washington, D.C. and principal investigator for one of Solar Orbiter’s ten instruments said in a mission update. “Now, we’ll be able to look down on the Sun from above.”

“It will be terra incognita,” added Daniel Müller, ESA project scientist for the mission at the European Space Research and Technology Centre in the Netherlands. “This is really exploratory science.”

Launched in 2018, Parker has now completed its first few close passes of the sun. The spacecraft is already making discoveries, showing that despite appearance, the sun is anything but quiet.

It plays a central role in shaping space around us. As a magnetically active star, the sun unleashes powerful bursts of light and a slew of charged particles (racing at near light-speed) across the solar system. This violent activity has been happening throughout the sun’s 5.5 billion-year lifespan and affects our planet daily.

The sun has a massive magnetic field, which stretches far beyond Pluto, and creates the boundary between our solar system and interstellar space. It also creates a path for charged particles to whiz across the solar system.

The barrage of energetic particles, known as the solar wind, can damage spacecraft, satellites, and is harmful to our astronauts. It can disrupt navigation signals, and during extreme flares, can even trigger power outages.

But we can prepare for these things by monitoring the sun’s activity and magnetic field. However, our view from Earth is limited and leaves us with incomplete data. Scientists are hoping that by observing the sun’s polar regions, Solar Orbiter will be able to fill in the gaps in our knowledge.

“The poles are particularly important for us to be able to model more accurately,” Holly Gilbert, NASA project scientist for the mission at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “For forecasting space weather events, we need a pretty accurate model of the global magnetic field of the Sun.”

Solar Orbiter will take seven years to reach a viewpoint 24 degrees above the Sun’s equator, increasing to 33 degrees if the mission is extended an additional three years. That will provide the best views ever of the poles.

Additionally, the poles may be able to shed some light on the driving force behind sun spots — dark spots on the sun’s surface that mark strong magnetic fields. In 1843, German astronomer, Samuel Heinrich Schwabe, discovered that the spots increase and decrease during the solar cycle in a repeating pattern.

There are an abundance of sunspots during solar maximum (when the sun is active and turbulent) and fewer during solar minimum (when the sun is calmer). But scientists don’t understand why the cycle lasts 11 years, or why some solar maximums are stronger than others.

They hope to find the answer by observing the changing magnetic fields at the poles.

There’s only been one other spacecraft to fly over the sun’s polar regions: another joint ESA/NASA venture called Ulysses. It made three passes around the sun before being decommissioned in 2009. However, unlike Solar Orbiter, Ulysses did not have an imager on board to take pictures of the poles.

That spacecraft also did not get nearly as close as Solar Orbiter will. That’s because it lacked the technology required to keep it cool. Scientists have been waiting more than 60 years for missions like Parker Solar Probe and Solar Orbiter to come online.

It’s takes a lot of technology development to be able to design and build a spacecraft that will survive a close encounter with the sun.

Solar Orbiter is outfitted with a custom-designed titanium heat shield, topped with a calcium phosphate coating that withstands temperatures over 900 degrees Fahrenheit (482 degrees Celsius). That’s thirteen times the amount of heat that spacecraft in Earth-orbit are subjected to.

Axiom Space’s Ax-4 mission is set to launch on a SpaceX Falcon 9 rocket. Ax-4 will advance diabetes research in microgravity, marking a milestone for astronaut health.

Axiom Space’s fourth crewed mission is scheduled to launch with SpaceX on May 29 from NASA’s Kennedy Space Center in Florida. The Ax-4 mission will carry a diverse crew and a record-breaking scientific payload to the International Space Station (ISS).

The Ax-4 crew is led by Axiom’s Peggy Whitson and includes Shubhanshu Shukla from India, Sławosz Uznański from the European Space Agency, and Tibor Kapu from Hungary. The mission represents firsts for India, Hungary, and Poland, with Uznański being Poland’s first astronaut in over 40 years.

Ax-4 will conduct nearly 60 science investigations from 31 countries during its two-week ISS stay. A key focus is the “Suite Ride” initiative, a collaboration with Burjeel Holdings to study diabetes management in microgravity.

“The effort marks a significant milestone in the long-term goal of supporting future astronauts with insulin-dependent diabetes (IDDM), a condition historically deemed disqualifying for spaceflight,” Axiom noted. The mission will test Continuous Glucose Monitors (CGMs) and insulin stability to assess their performance in space.

Axiom explained that testing the behavior of CGMs and insulin delivery technologies in microgravity and observing circadian rhythm disruption could help diabetes experts understand how CGMs and insulin pens can improve diabetes monitoring and care in remote or underserved areas on Earth. The research could benefit diabetes management in isolated regions like oil rigs or rural areas.

The mission’s findings on insulin exposure and CGM performance could pave the way for astronauts with diabetes to safely participate in spaceflight. As Axiom and SpaceX push boundaries, Ax-4’s diabetes research underscores the potential for space-based innovations to transform healthcare on Earth and beyond.

EU considers SES to augment Starlink services

The EU considers funding SES to support Starlink. With MEO satellites already serving NATO, SES could be key in Europe’s space autonomy push.

European satellite company SES is negotiating with the European Union (EU) and other governments to complement SpaceX’s Starlink, as Europe seeks home-grown space-based communication solutions. The talks aim to bolster regional resilience amid growing concerns over reliance on foreign providers.

In March, the European Commission contacted SES and France’s Eutelsat to assess their potential role if American-based Starlink access for Ukraine was disrupted. The European Commission proposed funding EU-based satellite operators to support Kyiv. Ukraine is considering alternatives to Starlink over concerns about Elon Musk’s reliability.

Arthur De Liedekerke of Rasmussen Global warned, “Elon Musk is, in fact, the guardian of Ukraine’s connectivity on the battlefield. And that’s a strategic vulnerability.” However, SpaceX’s Starlink constellation is leagues ahead of any competition in the EU.

“Now the discussions are much more strategic in nature. They’re much more mid-term, long-term. And what we’re seeing is all of the European governments are serious about increasing their defense spending. There are alternatives, not to completely replace Starlink, that’s not possible, but to augment and complement Starlink,” SES CEO Adel Al-Saleh told Reuters.

SES operates about 70 satellites, including over 20 medium Earth orbit (MEO) units at 8,000 km. The company provides high-speed internet for government, military, and underserved areas. It plans to expand its MEO fleet to 100, enhancing secure communications for NATO and the Pentagon.

“The most significant demand (for us) is European nations investing in space, much more than what they did before,” Al-Saleh said.

Competition from Starlink, Amazon’s Kuiper, and China’s SpaceSail, with their extensive low-Earth orbit constellations, underscores Europe’s push for independence.

“It is not right to say they just want to avoid Starlink or the Chinese. They want to avoid being dependent on one or two providers. They want to have flexibility,” Al-Saleh noted.

SES’s discussions reflect Europe’s strategic shift toward diversified satellite networks, balancing reliance on Starlink with regional capabilities. As governments ramp up defense spending, SES aims to play a pivotal role in complementing global providers, ensuring robust connectivity for military and civilian needs across the continent.

Amazon launches Kuiper satellites; Can it rival Starlink?

With 27 satellites in orbit, Amazon kicks off its $10B plan to deliver global broadband. Can Bezos’ Kuiper take on Musk’s Starlink?

Amazon’s Project Kuiper launched its first 27 satellites on Monday, marking the start of a $10 billion effort that could compete with SpaceX’s Starlink with a global broadband internet network.

Amazon’s Kuiper satellites launched aboard a United Launch Alliance Atlas V rocket from Cape Canaveral, Florida. Project Kuiper’s recent launch is the initial step toward deploying Amazon’s 3,236 satellites for low-Earth orbit connectivity. Amazon’s satellite launch was initially set for April 9 but was delayed due to bad weather.  

Now that the Kuiper satellites have been launched, Amazon is expected to publicly confirm contact with the satellites from its mission operations center in Redmond, Washington. The company aims to start offering Kuiper services to customers later this year. Project Kuiper was unveiled in 2019 and targets consumers, businesses, and governments who need reliable internet service, similar to Starlink.

Amazon has a deadline from the U.S. Federal Communications Commission to deploy 1,618 satellites by mid-2026. Analysts suggest the company may require an extension to its Kuiper satellite deployment deadline due to the project’s year-long delay from its planned 2024 start.

United Launch Alliance could conduct up to five more Kuiper missions this year, according to ULA CEO Tory Bruno. Amazon noted in a 2020 FCC filing that Kuiper services could begin with 578 satellites, initially covering northern and southern regions.

Kuiper’s launch pits Amazon against SpaceX’s Starlink and telecom giants like AT&T and T-Mobile, with a focus on underserved rural areas.

“There’s an insatiable demand for the internet,” Amazon Executive Chairman Jeff Bezos told Reuters in January. “There’s room for lots of winners there. I predict Starlink will continue to be successful, and I predict Kuiper will be successful as well.”

Global interest in satellite alternatives is rising. Ukraine is exploring Starlink alternatives with the European Union (EU), driven by concerns over Elon Musk. Germany’s military, Bundeswehr, also plans its own constellation to ensure independent communications. However, like Amazon’s Kuiper Project, EU options lag behind Starlink.

Amazon’s consumer expertise and cloud computing infrastructure give Kuiper a competitive edge despite Starlink’s market lead. As Kuiper ramps up launches, its success could reshape broadband access while challenging SpaceX’s dominance in the satellite internet race.
