The European Space Agency’s (ESA) Solar Orbiter spacecraft is traveling through the cosmos. Its destination: the inner solar system. The 3,900-lb. (1,800-kg) spacecraft will work in tandem with NASA’s Parker Solar Probe to unravel solar mysteries that have puzzled scientists for decades.

The probe will spend the next two years cruising towards the sun and using both Venus and the Earth to slingshot itself out of the ecliptic plane — the area of space where all planets orbit. This vantage point will allow the spacecraft to eventually look down upon the sun’s polar regions and snap the very first images of this crucial area.

“We believe this area holds the keys to unraveling the mysteries of the sun’s activity cycle,” Daniel Müller, the mission’s ESA project scientist, said in a prelaunch science briefing on Feb. 7.

The Solar Orbiter and its suite of 10 specialized instruments will act as a mobile laboratory in space, tracking eruptions of solar materials from their origin on the surface of the sun, out into space, and all the way down to Earth.

“Our entire solar system is governed by the activity that comes from the sun,” Nicky Fox, director of NASA’s Heliophysics Division said during the mission’s science briefing. “There’s a continually streaming kind of soup of energetic particles that moves away from the sun and bathes all the planets. We call that the solar wind.”

Together, the solar wind and the sun’s magnetic field create a huge bubble known as the heliosphere, which shields the Earth from powerful interstellar radiation called cosmic rays.

Coronal mass ejections (CMEs) are energetic eruptions of solar material and when they make it to Earth, the solar particles can interact with our planet’s magnetic field to produce powerful electromagnetic fluctuations. Known as geomagnetic storms, they are troublesome because they’re known to disrupt technologies like communications systems and even power grids.

Additionally, they can also be dangerous to astronauts and satellites in space.  Solar Orbiter will help mitigate damages from these types of storms by helping scientists better predict when they might happen.

Solar Orbiter launched atop an Atlas V rocket on Feb. 9 at 11:03 p.m. EST (0403 GMT on Feb. 10). About an hour after liftoff, the spacecraft separated from the rocket’s upper stage as planned, extended its solar arrays and sent a signal back to Earth that it had power.

The spacecraft then spent the next several days deploying its communication antennas as well as its instrument boom.

Its first three months are what’s known as a commissioning phase, during which ground controllers will check out the onboard instruments to make sure everything is in working order. Two years from now, the spacecraft will be close enough to take its first detailed measurements of the sun, but we didn’t have to wait that long for the first bits of science data to come in.

Solar Orbiter carries ten scientific instruments, four in situ (meaning they measure the environment around the spacecraft) and six remote-sensing imagers (which will measure the sun’s properties). The majority of the in situ instruments are located on a 4.4-m-long extendable boom. They study the electromagnetic characteristics of the solar wind, as well as the stream of charged particles flowing from the Sun.

“We measure magnetic fields thousands of times smaller than those we are familiar with on Earth,” Tim Horbury, principal investigator for the magnetometer (MAG) instrument on the Solar Orbiter, said in the statement. “Even currents in electrical wires make magnetic fields far larger than what we need to measure. That’s why our sensors are on a boom, to keep them away from all the electrical activity inside the spacecraft.”

Designed to measure the strength and direction of the magnetic field, the MAG (which is composed of two sensors) was the first instrument to send back data.

“The data we received shows how the magnetic field decreases from the vicinity of the spacecraft to where the instruments are actually deployed,” Horbury said in the same statement. “This is an independent confirmation that the boom actually deployed and that the instruments will, indeed, provide accurate scientific measurements in the future.”

The boom is a pole made constructed out of titanium and carbon-fiber that houses three instruments, which are so sensitive that they need to be kept away from the main body of the spacecraft to avoid potential electromagnetic disturbances.

“Measuring before, during, and after the boom deployment helps us to identify and characterize signals that are not linked to the solar wind, such as perturbations coming from the spacecraft platform and other instruments,” Matthieu Kretzschmar, lead co-investigator of the high-frequency magnetometer of the Radio and Plasma Waves instrument (RPW) instrument, which is also located on the boom and will study properties of the solar wind.

The team will continue to calibrate the spacecraft’s suite of instruments and will begin collecting official science data as early as May.

NASA’s first human outpost on the Moon starts now – SpaceX on deck

NASA named the rovers, landers, and vendors that will build America’s first Moon Base.

Published

NASA has laid out its most detailed Moon Base plan to date, describing a permanent outpost near the Moon’s south pole that the agency intends to build over the coming decade as a direct stepping stone to Mars. “The Moon Base will be America’s and humanity’s first outpost on another celestial world,” NASA Administrator Jared Isaacman said, adding that every mission crewed and uncrewed “will be a learning opportunity as we return to the lunar surface, build the infrastructure to stay, and master the skills required to live and operate in one of the most demanding and dangerous environments imaginable.”

The plan is structured in three phases involving both uncrewed and crewed missions to deliver equipment, vehicles, and infrastructure to the surface, with the first three moon base missions targeted to launch before the end of 2026.

Moon Base I, targeting fall 2026, will use Blue Origin’s Blue Moon Mark 1 lander to deliver scientific instruments to the Shackleton Connecting Ridge, the same region where Artemis astronauts will land. Moon Base II will send Astrobotic’s Griffin lander carrying more than 1,100 pounds of cargo including Astrolab’s FLIP rover to begin developing mobility systems on the surface. Moon Base III will carry the Lunar Vertex science mission on Intuitive Machines’ Nova-C Trinity lander to study lunar swirls near the south pole, with ESA and Korean science payloads aboard.

On the rover side, NASA awarded Astrolab $219 million and Lunar Outpost $220 million to build the first phase of Lunar Terrain Vehicles, with both rovers targeted for deployment to the lunar surface by 2028. Astrolab’s crewed rover weighs roughly 2,000 pounds and can reach over 6 mph. Lunar Outpost’s Pegasus rover can operate autonomously or via remote control at over 9 mph. Blue Origin separately received $188 million with an option worth $280.4 million to deliver cargo landers for rover transport.

NASA also confirmed that MoonFall, a mission deploying four survey drones to scout Artemis landing sites, has selected Firefly Aerospace to build the transport spacecraft, with a 2028 launch target.

SpaceX sits at the center of that commercial layer. SpaceX holds the NASA Human Landing System contract for the Starship-derived lander that will put astronauts on the surface under Artemis IV, currently targeting 2028. Before that can happen, SpaceX must demonstrate in-orbit propellant transfer at scale, a process requiring multiple Starship tanker launches to fuel a single mission. Water ice at the lunar south pole is central to the base’s long-term viability, as it can be converted into drinking water, breathable oxygen, and rocket fuel, directly reducing dependence on Earth resupply. That resource loop becomes far more practical if Starship can land and be refueled on or near the Moon itself.

Elon Musk has publicly stated that Starship V3, which recently completed its first flight, should be capable enough for initial Mars missions. The Moon Base plan announced Tuesday is the infrastructure layer that connects everything between those two ambitions, and SpaceX is the only American company currently contracted to build the rocket that gets humans to either destination.

SpaceX’s Starlink product has just gotten its latest airline adoptee, and the move marks the successful partnership of three of the “Big Four” U.S. airlines.

American Airlines announced on Tuesday that it would utilize Starlink in more than 500 narrowbody aircraft beginning in the first quarter of 2027. These include the Airbus aircraft in its fleet, including the new A321XLR and A321neo.

With the new partnership with American Airlines, Starlink is now present on three of the largest airlines in the country: American, United, and Southwest.

Starlink’s VP of Enterprise Sales, Jason Fritch, said:

“We are proud to bring Starlink on board American Airlines, delivering fast and reliable internet to passengers and crew. Whether traveling for leisure or business, Starlink enables a fully connected experience gate to gate, making every flight smoother and more enjoyable.”

Additionally, American Airlines Chief Customer Officer, Heather Garboden, said:

“As a premium global airline, we are continuously seeking out world-class partners like Starlink to deliver what our customers need and want. The addition of Starlink solidifies American as a leading airline in keeping passengers connected in flight.”

Starlink has been on a tear over the past year, as it has continued to be adopted by a wide variety of airlines as a more consistent and reliable way to provide WiFi to its passengers. It has already gained a great reputation among residential users, but its biggest commercial application appears to be how it is being used in the air.

The only airline of the Big Four not to adopt Starlink thus far is Delta, which chose to opt for the alternative, which is Amazon Leo. CEO Ed Bastian said to Bloomberg that Delta chose Amazon’s product over Starlink’s because “the opportunities, in terms of the improved bandwidth with a much lower price point than what we’ve ever seen from Starlink, will make a big difference.”

Delta will not start installing Amazon Leo until 2028.

“Of course, we expect Starlink will be warning people that we’re going to go with an inferior product,” Bastian said. “But I’m not too worried about partnering with Amazon.”

NASA just gave SpaceX more crew missions because Boeing can’t certify

Published

on

By

NASA has filed a procurement notice announcing its intent to add six post-certification missions to SpaceX’s existing Commercial Crew Transportation Capability contract. The agency said it would order up to three of those missions immediately upon adding them to the contract, with the remaining three available as needed through the end of the International Space Station’s planned operations in 2030.

The reason for the expansion is straightforward. NASA cited recently shortened ISS mission durations, technical issues and schedule delays encountered by Boeing, the allocation of missions between Boeing and SpaceX, and the ongoing technical challenges of maintaining a reliable crew transportation capability as the driving factors behind the decision. Boeing’s CST-100 Starliner has still not been certified for crewed flights, and a cargo-only Starliner mission was not included on NASA’s most recent mission manifest. With Boeing effectively sidelined for the foreseeable future, SpaceX is the only American company capable of rotating crews to the station.

SpaceX Board has set a Mars bonus for Elon Musk

The history behind this contract tells the fuller story of how SpaceX got here. NASA originally awarded SpaceX its Commercial Crew contract in 2014 for $2.6 billion. In 2022 NASA modified the contract to add five missions covering Crew-10 through Crew-14, worth $1.436 billion, bringing the total contract value at that point to $4.9 billion. The recent May 18 filing by NASA extends that runway further, with Crew-12 currently docked at the station and Crew-13 assigned and targeting a mid-September 2026 launch.

According to a report by SpaceNews, NASA stated in its filing: “It is necessary to award additional PCMs to SpaceX given the recently shortened ISS mission durations, technical issues and schedule delays encountered by Boeing, the allocation of missions between Boeing and SpaceX, NASA’s projections for when an alternative crew transportation system may become available, and the ongoing technical challenges of maintaining a reliable capability for crewed flights to ISS.”

No dollar value for the new six missions has been publicly confirmed yet, but based on the 2022 precedent of roughly $287 million per mission, the new block could represent close to $1.7 billion in additional contract value. With SpaceX simultaneously preparing Starship as NASA’s Artemis lunar lander, filing its S-1 for a June IPO, and now absorbing more ISS crew rotation work, the company’s role as the primary contractor for American human spaceflight is no longer a matter of circumstance. It is NASA policy.
